This video of a prototype, which uses an algorithm and solenoid valves for mixing CMYKW colors, has won me over though: It's unclear whether the colors are mixed on the fly as the colors are chosen and you write.

Features that make this a more professional machine are the 1600 watts of power (equivalent to the Breville Barista Express, our favorite espresso machine in our full guide), a three-way solenoid valve that prevents pressure from building up in the group head, which makes things a lot cleaner, and even less dangerous.

The solenoid type switching timers contain a solenoid that relieves pressure on a diaphragm in the water-flow tube or moves a stopper into the water flow area to regulate flow. The solenoid type uses no gears and makes a tapping sound when the solenoid is activated. Battery powered garden hose timers are the most commonly seen water timers and are seen in two types, the ball valve timer that is actuated by a motor with gears, and the diaphragm timer that is actuated by a solenoid. The solenoid/diaphragm timer uses more battery power throughout the "on" cycle because the solenoid must be actuated the entire time that the water flow is "on".

A solenoid bolt is a type of electronic-mechanical locking mechanism. This type of lock is characterized by the use of a solenoid to throw the bolt. Pawl & solenoid locking mechanism, Inventor(s): BUTTERWECK DIETER [DE]; PHILLIPS PETER J [US]; GARTNER KLAUS W [US] Sophisticated solenoid bolt locks may use microprocessors to perform voltage regulation, reduce power consumption, and/or provide access control. Depending on the strength of the solenoid, some models can provide a holding force on the order of 1000 kg.

A solenoid brake is an electrically controlled brake. The brake is turned on and off by an electrical solenoid. Typically a spring engages the brake when unpowered, and the solenoid releases it when powered. These are used along with a mechanical brake to manage the load on a cargo winch.
|
|
These interactions are important for solenoid formation. Histone variants can affect solenoid formation, for example H2A.Z is a histone variant of H2A, and it has a more acidic patch than the one on H2A, so H2A.Z would have a stronger interaction with histone H4 tails and probably contribute to solenoid formation.
|
|
In the context of meteorology, a solenoid is a tube-shaped region in the atmosphere where isobaric (constant pressure) and isopycnal (constant density) surfaces intersect, causing vertical circulation. They are so-named because they are driven by the solenoid term of the vorticity equation. Examples of solenoids include the sea breeze circulation and the mountain–plains solenoid.
|
|
The solenoid operation is fully controlled by the engine ECU.
|
|
These systems use an electrical switch to de-energise the solenoid valve and use an electrical relay attached to the actuator to re-energise the solenoid coil when the desired PST point is reached.
|
|
A 3-port pneumatic solenoid. This solenoid allows interrupt or blocking of the boost pressure rather than just bleed type control. Electronic boost control adds an air control solenoid and/or a stepper motor controlled by an electronic control unit. The same general principle of a manual controller is present, which is to control the air pressure presented to the wastegate actuator.
|
|
The pneumatic timer consists of a timing disk, filter, diaphragm, solenoid coil, operating spring and a solenoid core. When the pneumatic timer is energized, the solenoid core moves up into the coil. When this occurs, the core applies pressure on the diaphragm. This moves the diaphragm into the top chamber, air trapped in the chamber is expelled through the needle valve timing disk.
|
|
The solenoid tape was then folded over, so that it wrapped the twistor sheet, producing a series of U-shaped solenoids. Now another layer of the solenoid tape is laid over the first, the twistor tape folded over so it now runs along the negative Y axis across the top of the new solenoid tape, and then the solenoid tape is folded over to form a second set of loops. This process continues until the twistor strip is "used up", forming a compact cube of memory. Along one side of the memory, connected to each of the solenoid loops, was a series of small cores used solely for switching (their original purpose, development as a memory came later).

For a loop: So that the phase a charged particle gets when going in a loop is the magnetic flux through the loop. When a small solenoid has a magnetic flux, there are interference fringes for charged particles which go around the solenoid, or around different sides of the solenoid, which reveal its presence. But if all particle charges are integer multiples of , solenoids with a flux of have no interference fringes, because the phase factor for any charged particle is . Such a solenoid, if thin enough, is quantum-mechanically invisible.

In contrast to multimeters, solenoid voltmeters have no other built-in functions (such as the ability to act as an ammeter, ohmmeter, or capacitance meter); they are just simple, easy-to-use power voltmeters. Solenoid voltmeters are useless on low-voltage circuits (for example, 12 volt circuits). The basic range of the voltmeter starts at around 90V (AC or DC). Solenoid voltmeters are not precise.
|
|
Magnetic circuit breakers use a solenoid (electromagnet) whose pulling force increases with the current. Certain designs utilize electromagnetic forces in addition to those of the solenoid. The circuit breaker contacts are held closed by a latch. As the current in the solenoid increases beyond the rating of the circuit breaker, the solenoid's pull releases the latch, which lets the contacts open by spring action.

Examples of alpha solenoid structures binding RNA and lipids have also been described.
|
|
Each flap plate has its own pneumatically operated cylinder and solenoid valve. The timing of the valve is controlled by an electronic signal sent to the solenoid valves. This method of operation is the most expensive and allows for accurate timing of the valve.

|
Due to their propensity for forming large interaction surfaces well-suited to protein-protein interactions, and their flexible surfaces permitting binding of various cargo molecules, alpha solenoid proteins commonly function as transport proteins, particularly in transport between the nucleus and the cytoplasm. For example, the beta-karyopherin superfamily consists of alpha solenoid proteins formed from HEAT repeats; importin beta is a member of this family, and its adaptor protein importin alpha is an alpha solenoid formed from Armadillo repeats. Transporters of other molecules, such as RNA, can also be of alpha solenoid architecture, as in exportin-5 or pentatricopeptide-repeat-containing RNA- binding proteins, which are particularly common in plants.
|
|
The solenoid and stepper motors also need to be installed in such a way to maximize the advantages of failure modes. For instance, if a solenoid is installed to control boost electronically, it should be installed such that if the solenoid fails in the most common failure mode (probably non-energized position) the boost control falls back to simple wastegate actuator boost levels. It is possible a solenoid or stepper motor could get stuck in a position that lets no boost pressure reach the wastegate, causing boost to quickly rise out of control. The electronic systems, extra hoses, solenoids and soforth add complexity to the turbocharger system.

Freezer milling is a type of cryogenic milling that uses a solenoid to mill samples. The solenoid moves the grinding media back and forth inside the vial, grinding the sample down to analytical fineness. This type of milling is especially useful in milling temperature sensitive samples, as samples are milled at liquid nitrogen temperatures. The idea behind using a solenoid is that the only "moving part" in the system is the grinding media inside the vial.

|
The solenoid magnet surrounds both the COT and the silicon detector. The purpose of the solenoid is to bend the trajectory of charged particles in the COT and silicon detector by creating a magnetic field parallel to the beam. The solenoid has a radius of r=1.5 m and is 4.8 m in length. The curvature of the trajectory of the particles in the magnet field allows physicists to calculate the momentum of each of the particles.

|
Low sequence similarity among alpha solenoid proteins of similar structure has impeded their identification using bioinformatics methods, since the repeats are often not well defined in sequence. A large number of different computational methods have been developed to identify candidate alpha solenoid proteins based on their amino acid sequence.
|
|
Alpha solenoid proteins are found in all domains of life; however, their frequencies in different proteomes vary significantly. They are rare in viruses and bacteria, somewhat more common in archaea, and quite common in eukaryotes. Many of the eukaryotic alpha solenoid proteins have detectable homologs only in other eukaryotes and are often restricted even further, to the chordates. Prokaryotic alpha solenoid proteins are concentrated in particular taxa, notably the cyanobacteria and planctomycetes, which have unusually complex intracellular compartmentalization relative to most prokaryotes.
|
|
The boost control solenoid contains a needle valve that can open and close very quickly. By varying the pulse width to the solenoid, the solenoid valve can be commanded to be open a certain percentage of the time. This effectively alters the flow rate of air pressure through the valve, changing the rate at which air bleeds out of the T in the manifold pressure reference line to the wastegate. This effectively changes the air pressure as seen by the wastegate actuator diaphragm.

Starter motor diagram The electric starter motor or cranking motor is the most common type used on gasoline engines and small diesel engines. The modern starter motor is either a permanent-magnet or a series-parallel wound direct current electric motor with a starter solenoid (similar to a relay) mounted on it. When DC power from the starting battery is applied to the solenoid, usually through a key- operated switch (the "ignition switch"), the solenoid engages a lever that pushes out the drive pinion on the starter driveshaft and meshes the pinion with the starter ring gear on the flywheel of the engine. The solenoid also closes high-current contacts for the starter motor, which begins to turn.

Internally, the Ion features a spool-valve design, similar to a Shocker SFT or a Dye Matrix. However, the operation of the Ion is somewhat simpler than a Shocker SFT or Matrix in that it does not use a 4-way solenoid valve. The Ion's solenoid valve only has three hoses: one to provide air to the solenoid, one to provide air to a reservoir chamber behind the bolt, and the other which provides air to the front of the bolt to hold it back while the marker is at rest. The solenoid thus directs air either to the front of the bolt when not firing, or to the air reservoir behind the bolt, to blow it forward.

Electronic control systems use a configurable electronic module that connects between the supply from the ESD system and the solenoid valve. In order to perform a test the timer de-energises the solenoid valve to simulate a shutdown and re- energises the solenoid when the required degree of partial stroke is reached. These systems are fundamentally a miniature PLC dedicated to the testing of the valve. Due to their nature these devices do not actually form part of the safety function and are therefore 100% fail safe.

|
The fuel is sprayed with the help of a nozzle that is opened and closed with a needle valve, operated with a solenoid. When the solenoid is not activated, the spring forces the needle valve into the nozzle passage and prevents the injection of fuel into the cylinder. The solenoid lifts the needle valve from the valve seat, and fuel under pressure is sent in the engine cylinder. Third-generation common rail diesels use piezoelectric injectors for increased precision, with fuel pressures up to .

A solenoid voltmeter is a specific type of voltmeter electricians use to test electrical power circuits.Michael E. Brumbach Industrial electricity 7th ed. , Cengage Learning, 2004 , pp. 45-46 Wiggy is the registered trademark for a common solenoid voltmeter used in North America derived from a device patented in 1918 by George P. Wigginton.

The 4.5-Tesla magnetic field of a production solenoid will direct some of the particles produced into an S-shaped 2-Tesla evacuated transport solenoid, consisting of 50 separate superconducting electromagnets, which will select muons by charge and momentum, and carry the desired slow muons to the detector after some time delay.
|
|
The solenoid "opens" completely at 4,000 rpm. It has a 76mm bore and 88mm stroke with 9.5:1 Compression Ratio.
|
|
Armed with this knowledge, as long as boost pressure is below a predetermined allowable ceiling, the EMS will open the boost control solenoid to allow the turbocharger to create overboost beyond what the wastegate would normally allow. As overboost reaches the programmable maximum, the EMS begins to decrease the bleed rate through the control solenoid to raise boost pressure as seen at the wastegate actuator diaphragm so the wastegate opens enough to limit boost to the maximum configured level of over- boost. Stepper motors allow fine control of airflow based on position and speed of the motor, but may have low total airflow capability. Some systems use a solenoid in conjunction with a stepper motor, with the stepper motor allowing fine control and the solenoid coarse control.

|
Isoforms have between 6 and 10 of these repeats that form a coil, or beta-solenoid. One side of the solenoid has a flat ice-binding surface that consists of a double row of threonine residues. Other beetles (genus Rhagium) have longer repeats without internal disulfide bonds that form a compressed beta-solenoid (beta sandwich) with four rows of threonine residus, and this AFP is structurally similar to that modelled for the non-homologous AFP from the pale beauty moth. In contrast, the AFP from the spruce budworm moth is a solenoid that superficially resembles the Tenebrio protein, with a similar ice-binding surface, but it has a triangular cross-section, with longer repeats that lack the internal disulfide bonds.

|
Some manufacturers include a continuity test lamp function in a solenoid meter; these use the same probes as the voltage test function. This feature is useful when testing the status of contacts in energized circuits. The continuity light displays if the contact is closed, and the solenoid voltmeter shows voltage presence if open (and energized).
|
|
Alpha solenoids feature prominently in the proteins making up the nuclear pore complex (NPC); alpha solenoid and beta propeller domains together account for up to half of the core NPC scaffold by mass. A large number of the conserved nucleoporin proteins forming the NPC are either alpha solenoid proteins or consist of a beta propeller domain at the N-terminus and an alpha solenoid at the C-terminus. This latter domain architecture also occurs in clathrin and Sec31, and was thought to be unique to eukaryotes, though a few examples have been reported in planctomycetes.

CLEO has always used a solenoid magnet to allow the measurement of charged particles. The original CLEO design called for a superconducting solenoid, but it was clear that one could not be built in time. A conventional 0.42 T solenoid was installed first, then replaced by the superconducting magnet in September 1981. The superconducting coil was designed to operate at 1.2 T, but it was never operated above 1.0 T. A new magnet was built for the CLEO II upgrade and was placed between the calorimeter and the muon detector.

Directional valve, 5/3 sliding spool type, solenoid operated, showed on neutral position. P is pressure inlet, A and B are utilization ports, TA and TB are return ports. When solenoid (magnet) A is energized, the spool is pulled to left, connecting the ports P to A and the ports B to TB. When solenoid B is energized, the spool is pulled to right, connecting P to B and A to TA. They are widely used in the hydraulics industry. These valves make use of electromechanical solenoids for sliding of the spool.

The E-Grip is an electronic means of firing the marker. Utilizing battery operated components, the E-Grip replaces the trigger function, to where the trigger simply closes a micro switch. The switch sends a signal to a small circuit board, activating a solenoid. The solenoid uses a push rod to actuate the sear in this system.

A magnetic-hydraulic circuit breaker uses a solenoid coil to provide operating force to open the contacts. Magnetic-hydraulic breakers incorporate a hydraulic time delay feature using a viscous fluid. A spring restrains the core until the current exceeds the breaker rating. During an overload, the speed of the solenoid motion is restricted by the fluid.

Rather than using a D'Arsonval movement or digital electronics, the solenoid voltmeter simply uses a spring- loaded solenoid carrying a pointer (it might also be described as a form of moving iron meter). Greater voltage creates more magnetism pulling the solenoid's core in further against the spring loading, moving the pointer. A short scale converts the pointer's movement into the voltage reading.Kenneth G. Mastrullo, Ray A. Jones The Electrical Safety Program Book, Jones & Bartlett Learning, 2003 page 70 Solenoid voltmeters usually have a scale on each side of the pointer; one is calibrated for alternating current and one is calibrated for direct current.

Vps35 is the largest subunit of retromer with the molecular weight of 92-kDa and functions as the central platform for the assembly of Vps26 and Vps29. Vps35 resembles many other helical solenoid proteins including AP adaptor protein complexes that are characterized with repeated structural units in a continuous superhelix arrangement involved in coated vesicle trafficking. The curved surface of the 6 even-numbered helices within solenoid structure with series of ridges separating hydrophobic grooves function as potential cargo binding sites. The C-terminal of Vps35 contains an α-solenoid fold that fits into the metal binding pocket of Vps29.

Modern electronic automatic transmissions are still fundamentally hydraulic. This requires precise pressure control. Older automatic transmission designs only use a single line pressure control solenoid which modifies pressure across the entire transmission. Newer automatic transmission designs often use many pressure control solenoids, and sometimes allow the shift solenoids themselves to provide precise pressure control during shifts by ramping the solenoid on and off.

In 2004, the electronics side was improved greatly with the introductions of Electronic Throttle Control, electronically controlled transmissions, and transient engine and transmission controls. In addition, computing power was vastly increased. A solenoid control valve assembly integrated into the engine valley cover contains solenoid valves that provide a pressurized oil signal to specially designed hydraulic roller lifters provided by Eaton Corp. and Delphi.

|
This is exactly the opposite of the first port. The ability to help the wastegate remain closed as boost pressure builds can be increased. This also adds further complexity to boost control, requiring more control ports on the solenoid or possibly a complete second boost control system with its own separate solenoid. Use of the second port is not necessary.

Examination of the genome of Lokiarchaeum, thought to be among the closest archaeal relatives to eukaryotes, did not reveal any examples of the beta propeller/alpha solenoid domain architecture, although homologs of other proteins involved in eukaryotic membrane trafficking were identified. However, it is unclear whether this observation means that the propeller/solenoid architecture evolved later or was lost from modern lokiarchaea.

Connections on EUIs are by stainless steel- reinforced hoses. The controlled part of the injector is a solenoid-operated spill valve. Normally, it is open, allowing the fuel to return to the supply line when the pump plunger descends. When the solenoid is energized, the spill valve closes, and the fuel is forced through the spray tip into the cylinder.

The switching on of the ignition starts the engine and, in addition, automatically restarts the engine whenever it stalls, as long as the ignition is switched on.Startix, Automobile Topics Volume 110, Page 198, E E Schwarzkpf 1933 As soon as the ignition is switched on current flows to the first Startix solenoid and current flows from battery to starter. The generator delivers current once the engine starts and part of it goes to a second Startix solenoid that switches off the current from battery to starter. If the engine and generator stop, then that second solenoid switches on the current from the battery to the starter.

If such a solenoid were to carry a flux of , when the flux leaked out from one of its ends it would be indistinguishable from a monopole. Dirac's monopole solution in fact describes an infinitesimal line solenoid ending at a point, and the location of the solenoid is the singular part of the solution, the Dirac string. Dirac strings link monopoles and antimonopoles of opposite magnetic charge, although in Dirac's version, the string just goes off to infinity. The string is unobservable, so you can put it anywhere, and by using two coordinate patches, the field in each patch can be made nonsingular by sliding the string to where it cannot be seen.

The salt was magnetized along the axis of high g-factor, and the temperature was lowered to 1.2 K by pumping the helium to low pressure. Shutting off the horizontal magnetic field resulted in the temperature decreasing to about 0.003 K. The horizontal magnet was opened up, allowing room for a vertical solenoid to be introduced and switched on to align the cobalt nuclei either upwards or downwards. Only a negligible increase in temperature was caused by the solenoid magnetic field, since the magnetic field orientation of the solenoid was in the direction of low g-factor. This method of achieving high polarization of 60Co nuclei had been originated by Gorter and Rose.

Solenoid voltmeters draw appreciable current in operation. This makes them useful for testing residual-current devices (GFCIs) because the current drawn trips most RCDs when the solenoid voltmeter is connected between the live and earth conductors. Also, when testing power supply circuits, a high-impedance connection (that is, a nearly open-circuit fault such as a burned switch contact or wire joint) in the power path might still allow enough voltage/current through to register on a high-impedance digital voltmeter, but it probably can't actuate the solenoid voltmeter. For use with high impedance circuit applications, however, they are not so good, as they draw appreciable current and therefore alter the voltage being measured.

A typical tape might have five twistor wires and their returns, so the sheet was just over an inch wide. The solenoid was similarly constructed, consisting of a number of 0.15 inch wide copper tapes laminated into a plastic tape of the same basic dimensions as the twistor. Unlike a traditional solenoid with many turns of wire around an open core, this system was essentially nothing more than single wires in a sheet of plastic. To build the complete memory system, a sheet of the solenoid was laid out flat, say along the X direction, and then a sheet of the twistor was laid on top at right angles to it along the Y axis.

The solenoid valve controls the air pressure coming from the input air line (the small green tube). The output air from the solenoid valve is fed to the chamber in the middle of the actuator, increasing the pressure. The pressure in the actuator's chamber pushes the pistons away. While the pistons are moving apart from each other, the attached racks are also moved along the pistons in the opposite directions of the two racks.

When the engine cutoff signal was received by the electrical control package, it de-energized the main-stage and ignition phase solenoid valves and energized the helium control solenoid de-energizer timer. This, in turn, permitted closing pressure to the main fuel, main oxidizer, gas generator control, and augmented spark igniter valves. The oxidizer turbine bypass valve and propellant bleed valves opened and the gas generator and LOX dome purges were initiated.

Z-axis drive and control are handled in several ways. The first and most common is a simple solenoid that pushes against a spring. When the solenoid is energized it pushes the milling head down against a spring stop that limits the downward travel. The rate of descent as well as the amount of force exerted on the spring stop must be manually set by mechanically adjusting the position of the solenoid's plunger.

Magnetic Conversion FactorsEMF Fundamentals Everything2.com • OerstedDerived CGS Units with Special Names The H-field strength inside a long solenoid wound with 79.58 turns per meter of a wire carrying 1 A is approximately 1 oersted. The preceding statement is exactly correct if the solenoid considered is infinite in length with the current evenly distributed over its surface. The oersted is closely related to the gauss, the CGS unit of magnetic flux density.

Similar preshower detectors capped the ends of the tracking region. The material in the solenoid augmented with lead sheets caused primary electrons and photons to begin a shower of secondary particles. The preshower detector was thus the first stage of the calorimetry and gave a precise location of the particle impact point. A central calorimeter outside and two end calorimeters capping the solenoid contained separate sections for measuring electromagnetic particles and hadrons.

Positioned close to the magnet is a solenoid. By pulsing the solenoid coil with the appropriate electrical polarity, the permanent magnet on the axle will align itself with the magnetic field, also turning the disc. Another style uses a magnet embedded in the disc itself, with separate solenoids arranged at the ends or side to flip it. A computerized driver system reads data, typically characters, and flips the appropriate discs to produce the desired display.

The output is proportional to both the applied magnetic field and the applied sensor voltage. If the magnetic field is applied by a solenoid, the sensor output is proportional to the product of the current through the solenoid and the sensor voltage. As most applications requiring computation are now performed by small digital computers, the remaining useful application is in power sensing, which combines current sensing with voltage sensing in a single Hall effect device.

The DI/APC system managed knock not only by decreasing boost via a solenoid but by retarding ignition timing as well; DI/APC also managed the engine's basic ignition timing.

This increases wear on both sets of teeth. For this reason the Bendix drive has been largely superseded in starter motor design by the pre-engagement system using a starter solenoid.
|
|
Once the dwell time has passed, the solenoid returns the hammer (and thus the bolt) to the full-back position by routing the LPR-sourced air back through the default passage.

They further stated the pilot could not extend the gear by use of the backup hydraulic pump because the gear down solenoid had overheated during attempts to lower the gear and froze in the gear up position. After the solenoid cooled after landing they were able to manually lower the gear. Probable cause(s): Undetected chafing and grounding of a wire to the nose landing gear squat switch which resulted in the landing gear being signaled at all times for gear up when electrical power was applied to the system. Contributing to the accident was the overheating of the gear down solenoid which caused it to stick in the gear up position and prevented the gear from being manually extended.
|
|
When the Ion is fired, the air in front of the bolt that holds it back is drained back through the solenoid, which causes the air in the rear of the firing chamber to blow the bolt forward. In order to expedite the draining of air from the front of the bolt, many users add a quick exhaust valve (QEV) to their marker. The QEV replaces a fitting on the Ion's body and allows the draining air to vent into the body cavity instead of passing all the way back through the solenoid. By allowing the air to vent faster, this allows the bolt to close faster and with more force, which permits lower operating pressure and dwell (the time the solenoid valve is open).

Ford issued a nonstandard starter, a direct-drive "movable pole shoe" design that provided cost reduction rather than electrical or mechanical benefits. This type of starter eliminated the solenoid, replacing it with a movable pole shoe and a separate starter relay. This starter operates as follows: The driver turns the key, activating the starter switch. A small electric current flows through the solenoid actuated starter relay, closing the contacts and sending large battery current to the starter motor.

The cold start system has a solenoid valve and a glow filament which are connected in series. When starting the engine, diesel fuel comes through the solenoid valve and gets heated at the glow filament, the diesel fuel evaporates. It gets ignited at the last glow filament. The heat increases the temperature of the air from the intake manifold and makes it possible to start the engine unless the temperature level is not below -15 °C.

3D printing of a solenoid microcoil using a conductive mixture of polylactide and carbon nanotubes. Microcoils produced by electroplating copper on Spirulina bacteria. A microcoil is a tiny electrical conductor such as a wire in the shape of a spiral or helix which could be a solenoid or a planar structure. One field where these are found is nuclear magnetic resonance (NMR) spectroscopy, where it identifies radio frequency (RF) coils that are smaller than 1 mm.

Chromatin can form a tertiary chromatin structure and be compacted even further than the solenoid structure by forming supercoils which have a diameter of around 700 nm. This supercoil is formed by regions of DNA called scaffold/matrix attachment regions (SMARs) attaching to a central scaffolding matrix in the nucleus creating loops of solenoid chromatin between 4.5 and 112 kilobase pairs long. The central scaffolding matrix itself forms a spiral shape for an additional layer of compaction.

In a magnetic field, the electrons and nuclei of the plasma circle the magnetic lines of force. One way to provide some confinement would be to place a tube of fuel inside the open core of a solenoid. A solenoid creates magnetic lines running down its center, and fuel would be held away from the walls by orbiting these lines of force. But such an arrangement does not confine the plasma along the length of the tube.

A variable force solenoid (VFS) is an electro-hydraulic device that controls pressure proportionally or inversely proportionally to a signal (voltage or current) obtained from the on-board controller of a powertrain. A low flow VFS is used as a signal level devices for transmission line pressure control or application of clutches. A high flow VFS controls line pressure directly or are used for direct shift clutch control. A VFS is a type of Transmission Solenoid.
|
|
A plasma in a solenoid will spiral about the lines of field running down its center, preventing motion towards the sides. However, this does not prevent motion towards the ends. The obvious solution is to bend the solenoid around into a circle, forming a torus. However, it was demonstrated that such an arrangement is not uniform; for purely geometric reasons, the field on the outside edge of the torus is lower than on the inside edge.

A weak point in early balance wheel electric watches was the switch contacts on the balance wheel, which turned the solenoid on briefly to provide the impulse to keep the wheel oscillating. These wore out and did not operate reliably.The Electric Watch Repair Manual, Henry B. Fried, 1965, B. Jadow and Sons Publishers, Library of Congress Card Number 65-18620, p.59, "SPARKING: ITS CAUSES AND CURES" Later designs used electromagnetic sensing, with a transistor in the circuit to turn the solenoid on.

Many structural nucleoporins contain solenoid protein domains, domains consisting of repeats that can be stacked together as bulk building blocks. There are beta-propeller domain with similarities to WD40 repeats, and more interestingly, unique types of alpha solenoid (bundles of helixes) repeats that form a class of their own, the ancestral coatomer elements (ACE). To date, two classes of ACEs have been identified. ACE1 is a 28-helix domain found in many scaffolding nucleoproteins as well as SEC31, a component of COPII.

GS Promaster, courtesy of Greg Schutte Prototypes for a GS Promaster and an ND Promaster were designed but not released. The GS Promaster was designed by ICD tech Greg Schutte. It has the ICD aftermarket cylinder assembly, BlueFork modified stock ICD LPR, HPR, new ICD clamping feedneck, stock grips, Humphrey high-flow solenoid (same solenoid used in the Freestyle pro) and full predator coding v. 5.0. The GS Promaster looks much like the regular Promaster with a different "tail" design.

Solenoid model (left) and two- start twisted- ribbon model (right) of 30 nm fibre, showing DNA only. Several other models have been proposed and there is still a lot of uncertainty about the structure of the 30 nm fibre. Even the more recent research produces conflicting information. There is data from electron microscopy measurements of the 30 nm fibre dimensions that has physical constraints which mean it can only be modelled with a one-start helical structure like the solenoid structure.

Like a music box, the length of each reed affects its resonant frequency. The reeds are powered magnetically, by a single solenoid coil and an iron core wrapped between the ends of the reeds. A reed's resonant frequency is a mid-range audible frequency of perhaps 300 Hz. The solenoid is driven by the output of the radio control receiver,Receivers in use at this time would be 27 MHz AM superhet receivers. which is an audio tone or tones.

Most Quadrajets use a vacuum operated piston to move the primary metering rods to control the air-fuel ratio, allowing the mixture to be lean under low load conditions and rich during high load conditions. A less-common version uses a linkage driven off the primary throttle shaft to mechanically move the power piston. "E" (electronic control module controlled) series of Quadrajets use a computer controlled mixture control solenoid that responds to electronic signals from the throttle position and oxygen sensors via the computer, ideal for precise fuel metering and allowing additional fuel under load. The solenoid-controlled metering rods allow the fuel mixture to be very close to optimum, then the solenoid is pulse width modulated at about 6 Hz to fine-tune the air fuel ratio under closed loop conditions.

Many configurations are possible with 2-, 3-, and 4-port solenoids and stepper motors in series or parallel. Two-port solenoid bleed systems with a PID controller tend to be common on factory turbocharged cars.

The term "alpha solenoid" has been used somewhat inconsistently in the literature. As originally defined, alpha solenoids were composed of helix-turn-helix motifs that stacked into an open superhelix. However, protein structural classification systems have used varying terminology; the Structural Classification of Proteins (SCOP) database describes these proteins using the term "alpha alpha superhelix". The CATH database uses the term "alpha horseshoe" for these proteins, and uses "alpha solenoid" for a somewhat different and more compact structure exemplified by the peridinin-chlorophyll binding protein.

The solenoid structure's most obvious function is to help package the DNA so that it is small enough to fit into the nucleus. This is a big task as the nucleus of a mammalian cell has a diameter of approximately 6 µm, whilst the DNA in one human cell would stretch to just over 2 metres long if it were unwound. The "beads on a string" structure can compact DNA to 7 times smaller. The solenoid structure can increase this to be 40 times smaller.

In 2018 Bluegrass supported General Atomics by cutting a ¼ scale mockup of the ITER solenoid constructed by wrapping 288 individual stainless steel bars with copper conductor and coiling the resulting “superconductor” into a ring 3 ft tall x 2 ½ ft wide. The heart of the ITER tokamak, a solenoid is used to magnetically confine a plasma of reactive charged particles into a hollow doughnut-shaped container. The ring of stainless steel and copper was segmented into 4 pieces sized for shipment to another facility for analysis.

A simple confinement system can be made by placing a tube inside the open core of a solenoid. The tube can be evacuated and then filled with the requisite gas and heated until it becomes a plasma. The plasma naturally wants to expand outwards to the walls of the tube, as well as move along it, towards the ends. The solenoid creates magnetic field lines running down the center of the tube, and the plasma particles orbit these lines, preventing their motion towards the sides.

Shift blocking is a feature of automobile manual transmissions added to improve fuel economy ratings in the Corporate Average Fuel Economy (CAFE) system by preventing a driver from switching from first gear to second or third as would be done normally. A solenoid prevents the shifter from engaging these gears, forcing the driver to shift from first to fourth gear. The solenoid is computer controlled, and will deactivate if the throttle is opened wide enough, or the car reaches speeds above those typical in city driving.

The control unit is the processing unit which decides how to react with the incoming signals get a desired land level. It adjusts the height of the scraper by activating or deactivating the electro-hydraulic actuators (solenoid valves). Generally these are ON OFF type solenoid valves but some modern systems use proportional valves . On the dash board of control unit there are some keys and indicators are provided as user interface through which user can monitor the operation or manually operate the machine when needed.
|
|
Another technique is to embed the control electronics into a solenoid valve enclosure removing the need for additional control boxes. In addition there is no need to change the control schematic as no dedicated components are required.

|
Linear (open) solenoid structure If the two terminal repeats in a solenoid do not physically interact, it leads to an open or linear structure. Members of this group are frequently rod- or crescent-shaped. The number of individual repeats can range from 2 to over 50. A clear advantage of this topology is that both the N- and C-terminal ends are free to add new repeats and folds, or even remove existing ones during evolution without any gross impact on the structural stability of the entire domain.
|
|
A coil is wound around one of the magnets in a way that if we inject enough current (in a pulse) in the solenoid the generated magnetic field inside will be higher than the intrinsic coercivity of the magnet ( H_{ci} ). If this is the case the permanent magnet will be magnetized in the direction of the field inside the solenoid. Applying the same pulse of current in the opposite direction will lead to magnetize the magnet in the opposite direction. Therefore, we have the same behavior as when we mechanically rotate the magnet.

There are many factors that affect whether the solenoid structure will form or not. Some factors alter the structure of the 30 nm fibre, and some prevent it from forming in that region altogether. The concentration of ions, particularly divalent cations affects the structure of the 30 nm fibre, which is why Finch and Klug were not able to form solenoid structures in the presence of chelating agents. There is an acidic patch on the surface of histone H2A and histone H2B proteins which interacts with the tails of histone H4 proteins in adjacent nucleosomes.

There are 3 intake cam lobes: 2 for the low- RPM mode (1 for almost closed valve, 1 for normally opened) and 1 for the powerful mode when the VTEC solenoid is activated. The lowest RPM for activating the VTEC is 2500, or it may be higher if the load is weak - ECM dependant. With the VTEC solenoid is on the 3-rd biggest lobe begins to push all the intake valves with the more aggressively profile. This variant of the VTEC-E is used in the F23A engine.

The Hairpin tuner (top right) has the same circuit, but uses a “hairpin” inductor (a tapped transmission line, short-circuited at the far end). Moving the taps along the hairpin allows continuous adjustment of the impedance transformation, which is difficult with a solenoid coil. It is useful for very short wavelengths from about 10 meters to 70 cm (frequencies about 30 MHz to 430 MHz) where the solenoid inductor would have too few turns to allow fine adjustment. These tuners typically operate over at most a 2:1 frequency range.

In at least some PCP forms, including that from A. carterae, these building blocks assemble into a trimer thought to be the biologically functional state. When the X-ray crystallography structure of PCP was solved in 1997, it represented a novel protein fold, and its topology remains unique among known proteins. The structure is referred to by the CATH database, which systematically classifies protein structures, as an "alpha solenoid" fold; however, elsewhere in the literature the term alpha solenoid is used for open and less compact helical protein structures.

The magnetic lock relies upon some of the basic concepts of electromagnetism. Essentially it consists of an electromagnet attracting a conductor with a force large enough to prevent the door from being opened. In a more detailed examination, the device makes use of the fact that a current through one or more loops of wire (known as a solenoid) produces a magnetic field. This works in free space, but if the solenoid is wrapped around a ferromagnetic core such as soft iron the effect of the field is greatly amplified.
|
|
An early iteration of the Twistor comprised a twisted ferromagnetic wire threaded through a series of concentric solenoids (see attached photo of a test rig for a single "bit"). The longer solenoid is the SENSE coil, the shorter one the WRITE coil. A single bit was written by pulsing the WRITE coil with a + (1) or - (0) current sufficient to magnetize the helical area beneath the coil in one of two directions. At one end of the stretched wire was the READ solenoid - when pulsed it sent an acoustic wave through the wire.
|
|
Writing to twistor was effectively identical to core; a particular bit was selected by powering one of the twistor wires and one of the solenoid loops to one half of the required power, such that the required field strength was created only at the intersection of the two. Reading used a different process. Unlike core, twistor did not have a sense/inhibit line. Instead, it used a larger current in the solenoid, large enough to flip all of the bits in that loop, and then used the twistor wires as the read line.
|
|
Read operations in the piggyback are identical to the permanent magnet version. Writes were slightly more complex, due to the fact that piggyback twistors all featured the magnetic tape along the entire length of the X wire. This meant that any one solenoid was wrapping both the bit that is being written as well as the one on the section of return wire. To set the one both and not the other, the solenoid was first powered in one direction and then the other, while the current in the twistor line remained constant.
|
|
Due to the identical form of their building blocks, solenoid domains can only assume a limited number of shapes. Two main topologies are possible: linear (or open, generally with some degree of helical curvature) and circular (or closed).

One of the largest manufacturers was the Veeder-Root company, and their name was often used for this type of counter.. Mechanical counters can be made into electromechanical counters, that count electrical impulses, by adding a small solenoid.

Upon obtaining "engine ready" and "start" signals, solenoid control valves were energized in a precisely timed sequence to bring the engine through ignition, transition, and into main-stage operation. After shutdown, the system automatically reset for a subsequent restart.

A solenoid bolt can be designed either to fail open (the lock opens on power loss) or to fail closed (the device is locked upon power loss); cf fail safe. Some models may be suitable for high-security sites.

The origin of the electropneumatic paintball marker is the subject of a patent dispute,Smart Parts Lawsuit (blocked link) but is generally acknowledged to have happened more or less simultaneously with the introduction of WDP's Angel and PneuVenture's Shocker, marketed by Smart Parts, both in 1996. The markers were operated differently; they were similar only to the extent that they both make use of one or more microswitch-controlled solenoid valves. The Shocker used two solenoid-operated control valves in order to obtain separate controls over the ball loading sequence and the air delivery sequence. The Angel made use of a linked hammer and bolt assembly, which permitted the use of a single solenoid to actuate the entire firing sequence by controlling a piston that powered the hammer/bolt assembly forward, simultaneously chambering a paintball and releasing the propulsion gases at the end of the hammer's stroke.

Solenoidal has its origin in the Greek word for solenoid, which is σωληνοειδές (sōlēnoeidēs) meaning pipe-shaped, from σωλην (sōlēn) or pipe. In the present context of solenoidal it means constrained as if in a pipe, so with a fixed volume.

In the base sub complex, Rpn1 offers a docking position for subunit Rpn10 at its central solenoid portion, although such association with Rpn10 is stabilized by a third subunit, Rpn2. Rpn10 serve as a receptor for poly-ubiquitylated protein substrates.

The QEV also acts as a trap for excess grease that might otherwise enter the solenoid and cause problems. Two other markers manufactured by Smart Parts, the SP-8 and the Epiphany, are based on the Ion's spool-valve design.

Wig wag solenoid in a washing machine The wig-wag is the common name for the unusual solenoid mechanism used in belt-drive washing machines made by Whirlpool, Kenmore (manufactured by Whirlpool) and many others, from approximately 1950 to 1987 in the United States. It was used in belt-drive Brastemp and Consul models built in Brazil from 1959 to 1990. They were common in US-style top-loading vertical-axis machines, not used in European front- loading horizontal-axis machines. Horizontal-axis machines rotate the drum to both agitate the clothes during washing and to spin them dry.

|
Circular (closed) solenoid domain In the case when the N- and C-terminal repeats lie in close physical contact in a solenoid domain, the result is a topologically compact, closed structure. Such domains typically display a high rotational symmetry (unlike open solenoids that only have translational symmetries), and assume a wheel-like shape. Because of the limitations of this structure, the number of individual repeats is not arbitrary. In the case of WD40 repeats (perhaps the largest family of closed solenoids) the number of repeats can range from 4 to 10 (more usually between 5 and 7).

|
Prefabricated mechanical screw valves and solenoid valves require no advanced microfabrication processes and are easy to implement in soft substrate materials like PDMS. Screw valves, unlike Quake and ice valves, maintain their level of flow restriction without power input, and are thus ideal for situations where the valve position may remain mostly constant and actuation by a human operator is acceptable. Electromagnetic solenoid valves have similar actuation times compared to Quake valves, but have larger footprints and are not integrated into the device substrate. This is an issue when device dimensions are an issue, such as in implantable devices.
|
|
A solenoid normally generates a linear magnetic field along the center of its axis, in this case through the middle of the vacuum chamber. When charged particles are placed in a magnetic field, they orbit around the field lines, which in this case causes them to stop moving sideways. In a normal solenoid, they would still be free to move along the lines and thus escape out the ends of the chamber. Post's insight was to wind the electromagnet in such a way that the field was stronger at the ends than in the center of the chamber.

An alpha solenoid (sometimes also known as an alpha horseshoe or as stacked pairs of alpha helices, abbreviated SPAH) is a protein fold composed of repeating alpha helix subunits, commonly helix-turn- helix motifs, arranged in antiparallel fashion to form a superhelix. Alpha solenoids are known for their flexibility and plasticity. Like beta propellers, alpha solenoids are a form of solenoid protein domain commonly found in the proteins comprising the nuclear pore complex. They are also common in membrane coat proteins known as coatomers, such as clathrin, and in regulatory proteins that form extensive protein-protein interactions with their binding partners.

The LINC keyboard, manufactured by company named Soroban Engineering, had a unique locking solenoid. The internal mechanism of each key had a slot that worked with a set of bars to encode the character and another slot that caught a locking bar, which locked all the keys in one mechanical movement of the locking solenoid. When the user pressed a key, the pressed key was locked in its down position, and all the other keys were locked in the up position. When the running program read the keyboard, the lock was released, and the pressed key would pop back up.

Separately, another machine is fed copper wire and periodically creates small coils of ten windings forming a solenoid. The assembly machinery then left a short section of the wire unbent, before winding another solenoid into the wire, and so on. The result is a string of coils on the wire, which from a distance looked like a series of knots evenly spaced along a rope. A number of these ropes were then laid parallel to each other and a second set of straight wires run parallel to the ropes so they lay under one end of the solenoids.

Operational challenges of the LHC. cea.fr The niobium-titanium (Nb-Ti) magnets operate at 1.9 K to allow them to run safely at 8.3 T. Each magnet stores 7 MJ. In total the magnets store . Once or twice a day, as the protons are accelerated from 450 GeV to 7 TeV, the field of the superconducting bending magnets will be increased from 0.54 T to 8.3 T. The central solenoid and toroidal field superconducting magnets designed for the ITER fusion reactor use niobium-tin (Nb3Sn) as a superconductor. The Central Solenoid coil will carry 46 kA and produce a field of 13.5 teslas.

Twistor could be modified to produce a ROM that could be easily re-programmed. To do this, one-half of each solenoid loop was replaced with an aluminum card into which tiny vicalloy bar magnets were embedded. As the solenoids have to be complete circuits in order for current to flow through them, they were still inserted as folded sheets, but in this case the loop was inserted between the folds of twistor instead of around them. This allowed the single sheet to act as one half of a solenoid loop for two folds of the twistor, above and below.

Effect duration is determined by the heating cycle of the theatrical fog machine and consumption rate of liquid CO2. Carbon dioxide can also be used as an atmospheric effect on its own. When liquid CO2 is released into the air, typically through an electric solenoid valve to control timing and duration, the carbon dioxide liquid expands to a gas, locally lowering the temperature below the dew point, causing condensation of the water vapour in the air, creating large billowing fog plumes. When the solenoid valve is closed, the fog rapidly disperses in the air, ending the effect nearly instantaneously.

If the injector is damaged or dirty, a small amount of fuel can enter the chamber and be ignited, causing a sputter or two after the engine is switched off. Until the mass-market introduction of fuel injection, the industry's remedy for dieseling was to install an electric solenoid into the fuel supply circuit of the carburetor, energized by the ignition coil primary wire: when activated, the solenoid would open and allow fuel to flow normally out of the float bowl, through the fuel-metering jets and into the engine; when deactivated, the solenoid would close and prevent fuel from being drawn through the jets and into the engine. This provided a simple, adequate solution to the dieseling problem. Dieseling (in the sense of engine run-on, and disregarding combustible gaseous mixtures via the air intake) can also occur in diesel engines, when the piston or seals fail due to overheating, admitting engine oil into the cylinder.

The finished puppets were approximately tall, or adult human height.Peel, p. 18. The puppets were made up of more than 30 individual components, the most important of which was the solenoid that synchronised lip movements with the characters' pre-recorded dialogue.Archer, p. 72.

|
This problem is fixed by removing the felt pads, cleaning off the adhesive (isopropyl alcohol works well), and placing some electrical tape or other material to provide a cushion for the solenoid. Unfortunately, accessing the solenoids requires disassembling most of the input mechanism.

Evolutionary relationships between different alpha solenoid proteins are difficult to trace due to the low sequence homology of the repeats. Convergent evolution of similar protein structures from ancestrally unrelated proteins is thought to be significant in the evolutionary history of this fold class.

Form A contacts ("make contacts") are normally open contacts. The contacts are open when the energizing force (magnet or relay solenoid) is not present. When the energizing force is present, the contact will close. An alternate notation for Form A is SPST-NO.

The probe handle, being made of a non-ferrous material, has no disturbing effect on the field. A Hall probe should be calibrated against a known value of magnetic field strength. For a solenoid the Hall probe is placed in the centre.

While electric dipoles can be understood as separated charges and magnetic dipoles as circular currents, axial (or electric) toroidal dipoles describes toroidal charge arrangements whereas polar (or magnetic) toroidal dipole (also called anapole) correspond to the field of a solenoid bent into a torus.

There are three failures with the wig- wag mechanism. The first is that a solenoid tends to jam, often due to corrosion from operating in a damp environment or grease/dirt getting into the solenoid and preventing gravity from making the pin drop. The second common failure is peculiar to the wig-wag - since the wires which operate the solenoids are constantly being flexed by the motion of the wig-wag, they tend to break causing the wash or spin cycle not to engage. The third typical failure is a short inside a solenoid's coil, which will eventually burn out the coil itself and create a discontinuity within it.

Slingshots have rubber pads which detect the ball's impact and automatically push it away at speed Kickers and slingshots are rubber pads which propel the ball away upon impact, like bumpers, but are usually a horizontal side of a wall. Every recent pinball machine includes slingshots to the upper left and upper right of the lowest set of flippers; older games used more experimental arrangements. They operate similarly to pop bumpers, with a switch on each side of a solenoid-operated lever arm in a typical arrangement. The switches are closed by ball contact with the rubber on the face of the kicker and this activates the solenoid.

The line printer ran at 600 lines per minute, using a continuously rotating print drum technology, with letters, figures and punctuation marks distributed around the drum at each column. 132 solenoid-operated flat-faced print hammers comprised a print line, with ten characters to the inch. When a desired character arrived at the printing position, as indicated by timing marks on the end of the drum, a thyratron would fire and energize a print column solenoid, propelling its hammer to the back face of the printing paper. The paper would be bounced against a wide inked ribbon and against the drum, printing the desired character.

The electrohydraulic servo valve first appeared in World War II. The EHSVs in use during the 1940s were characterized by poor accuracy and slow response times due to the inability to rapidly convert electrical signals into hydraulic flows. The first two-stage servo valve used a solenoid to actuate a first stage spool which in turn drove a rotating main stage.Servo valve Review The servo valves of the World War II era were similar to this — using a solenoid to drive a spool valve. Advancement of EHSVs took off in the 1950s, largely due to the adoption of permanent magnet torque motors as the first stage (as opposed to solenoids).

They are sometimes considered to occupy an intermediate position between globular proteins and fibrous structural proteins, distinct from the latter in part due to the alpha solenoids' lack of need for intermolecular interactions to maintain their structure. The extent of the curvature of an alpha solenoid superhelix varies considerably among the class, resulting in the ability of these proteins to form large, extended protein-protein interaction surfaces or to form deep concave areas for binding globular proteins. Because they are composed of repeating relatively short subunits, alpha solenoids can acquire additional subunits relatively easily, resulting in new interaction surface properties. As a result, known alpha solenoid proteins vary substantially in length.

This lower pressure air is supplied to the front of the bolt, and the regulator is adjusted to supply enough force to push the bolt back against the supply pressure. When the solenoid valve is energized the air in front of the bolt vents, allowing the bias supplied to the rear of the bolt to move it forward. When the bolt has moved forward enough to seal the breech, the pin unseals from the powertube it rides in, and air is vented through the bolt to the ball, firing it. When the solenoid valve is de-energized, air is again supplied to the front of the bolt to return it.

On more modern transmissions this input allows the TCU to modify the line pressure and solenoid pressures according to the changing viscosity of the fluid based on temperature in order to improve shift comfort, and also to determine regulation of the torque converter lock-up clutch.

Unlike other electropneumatic spool valve markers on the market, which use a solenoid valve to actuate the movement of the bolt, the SLG operates using a spool valve actuated by a mechanical solenoid and sear. This unique single-tube, sear-tripping, blow- forward operation is comparable to, though not identical to, the operation of the Automag. In the SLG, the recocking mechanism is air pressure acting on a smaller, forward-facing area to push the bolt back open when the pressure in the dump chamber—which acts on a larger, rearward-facing area—reaches a low pressure from firing and venting the dump chamber. In the Automag, this is accomplished by the return spring.

In mathematics, a protorus is a compact connected topological abelian group. Equivalently, it is a projective limit of tori (products of a finite number of copies of the circle group), or the Pontryagin dual of a discrete torsion-free abelian group. Some examples of protori are given by solenoid groups.

The WD40 repeat (also known as the WD or beta-transducin repeat) is a short structural motif of approximately 40 amino acids, often terminating in a tryptophan-aspartic acid (W-D) dipeptide. Tandem copies of these repeats typically fold together to form a type of circular solenoid protein domain called the WD40 domain.

If pressure rose in the ballonet, a spring would pressure the spindle of the butterfly valve to turn, relieving the pressure. In more recent implementations, the valves are actuated electrically either by a linear actuator (driven open/closed) or a linear solenoid (spring return), the latter being the favored fail-to-safe arrangement.

After the Endurance course was closed, the now cooled down car was brought back to the paddock where it fired up immediately with no charging of the battery. MIS Endurance Due to the problems in the VIR Endurance and in testing, a larger battery was added to the car for this event (14 amp-hour), and a second fan was installed on the radiator as well as a duct in front of the radiator. After about 7 laps by the first driver the downshift microswitch got stuck and held the pneumatic actuator in the down- shift position. The transmission ended up in first gear, and would not come out of first because the up-shift solenoid could not overcome the already actuated down-shift solenoid.

|
The reason for this is that at liquid nitrogen temperatures (–196°C) any moving part will come under huge stress leading to potentially poor reliability. Cryogenic milling using a solenoid has been used for over 50 years and has been proved to be a very reliable method of processing temperature sensitive samples in the laboratory.

In his design electromagnets were energized to attract iron rods attached to a rotating flywheel. At the moment that an iron rod reached the electromagnet, the power to the solenoid was interrupted until the next iron rod approached the electromagnet. On his death in 1865 he was buried in the Père-Lachaise cemetery in Paris.

This measurement impacts the parameter space of supersymmetry. A combination with Compact Muon Solenoid (CMS) data from the completed 8 TeV run allowed for a precise measurement of the strange b-meson to dimuon branching fraction. CP violation was studied in various particle systems such as Bs, Kaons, and D0. New Xi baryons were observed in 2014.

Alternatively, an electro-mechanical oscillator driven by an AC-energized solenoid may be used. Some very early mechanical shavers had no electric motor and had to be powered by hand, for example by pulling a cord to drive a flywheel. Electric shavers fall into two main categories: foil or rotary- style. Users tend to prefer one or the other.

This input is used to determine whether to activate the shift lock solenoid to prevent the driver selecting a driving range with no foot on the brake. In more modern TCUs this input is also used to determine whether to downshift the transmission to increase engine braking effect if the transmission detects that the vehicle is going downhill.

Some front load washing machines use wax motors to engage the door lock assembly. When a cycle is started, a wax motor is actuated pushing a pin outward and locking the door. This design has cost, reliability and safety advantages. In moist conditions a wax motor costs less for equivalent reliability than an electromagnetic solenoid or motor latch.

They are used in many dishwashers to release the detergent dispenser door latch. The wax motor acts like a solenoid when activated by the dishwasher's timer or control, and the piston operates the mechanism which then releases the catch for the dispenser door. They are also used to control the exhaust vent for the drying cycle.

A method of reversing the car was offered on later models via a reversible Dynastart unit. The Dynastart unit, which doubled as both starter motor and dynamo on these models incorporated a built-in reversing solenoid switch. After stopping the engine and operating this switch the Dynastart, and consequently the engine, would rotate in the opposite direction.

A transmission solenoid or cylinoid is an electro-hydraulic valve that controls fluid flow into and throughout an automatic transmission. Solenoids can be normally open or normally closed. They operate via a voltage or current supplied by the transmission computer or controller. Transmission solenoids are usually installed in a transmission valve body, transmission control unit, or transmission control module.

Although the W85 was not accepted into Chinese service, years later a variant was adopted called the QJC-88. The QJC-88 was introduced as a pintle mounted machine gun for tanks and armored vehicles. It weighs the same, is solenoid fired, and is mounted on a special cradle allowing for elevation angles of -5 to +65°.

The term Compact Muon Solenoid comes from the relatively compact size of the detector, the fact that it detects muons, and the use of solenoids in the detector.Aczel, Ammir D. "Present at the Creation: Discovering the Higgs Boson". Random House, 2012 "CMS" is also a reference to the center-of- mass system, an important concept in particle physics.

Once the engine starts, the key-operated switch is opened, a spring in the solenoid assembly pulls the pinion gear away from the ring gear, and the starter motor stops. The starter's pinion is clutched to its drive shaft through an overrunning sprag clutch which permits the pinion to transmit drive in only one direction. In this manner, drive is transmitted through the pinion to the flywheel ring gear, but if the pinion remains engaged (as for example because the operator fails to release the key as soon as the engine starts, or if there is a short and the solenoid remains engaged), the pinion will spin independently of its drive shaft. This prevents the engine driving the starter, for such backdrive would cause the starter to spin so fast as to fly apart.

Solenoids may require small diameter restrictors be installed in the air control lines to limit airflow and even out the on/off nature of their operation. The wastegate control solenoid can be commanded to run in a variety of frequencies in various gears, engine speeds, or according to various other factors in a deterministic open-loop mode. Or, by monitoring manifold pressure in a feedback loop, the engine management system can monitor the efficacy of PWM changes in the boost control solenoid bleed rate at altering boost pressure in the intake manifold, increasing or decreasing the bleed rate to target a particular maximum boost. The basic algorithm sometimes involves the EMS (engine management system) "learning" how quickly the turbocharger can spool and how quickly the boost pressure increases.

An automobile starter motor (larger cylinder). The smaller object on top is a starter solenoid which controls power to the starter motor. A starter (also self-starter, cranking motor, or starter motor) is a device used to rotate (crank) an internal-combustion engine so as to initiate the engine's operation under its own power. Starters can be electric, pneumatic, or hydraulic.

Most automatic systems employ electric solenoid valves. Each zone has one or more of these valves that are wired to the controller. When the controller sends power to the valve, the valve opens, allowing water to flow to the sprinklers in that zone. There are two main types of sprinklers used in lawn irrigation, pop-up spray heads and rotors.

The implementation of AVCS is quite different from AVLS. The latter just changes which cam is operating one of the two valves. In AVCS, the engine computer (ECU) can command a solenoid which advances or retards the camshaft rotation by up to 35 degrees. By retarding the cams at idle or very low engine loads, you achieve a smoother, easier idle.

The ATHENA apparatus comprises four main subsystems: the antiproton catching trap, the positron accumulator, the antiproton/positron mixing trap, and the antihydrogen annihilation detector. All traps in the experiment are variations on the Penning trap, which uses an axial magnetic field to transversely confine the charged particles, and a series of hollow cylindrical electrodes to trap them axially (Fig. 1a). The catching and mixing traps are adjacent to each other, and coaxial with a 3 T magnetic field from a superconducting solenoid. The positron accumulator has its own magnetic system, also a solenoid, of 0.14 T. A separate cryogenic heat exchanger in the bore of the superconducting magnet cools the catching and mixing traps to about 15 K. The ATHENA apparatus features an open, modular design that allows great experimental flexibility, particularly in introducing large numbers of positrons into the apparatus.

Internal components of a 500-type telephone of 1951 View of the 425A network component of a model 500 of 1951 The electromechanical ringer consists of two bell gongs of slightly different dimensions to produce different pitches, and a striker between them that is driven by a solenoid; when the solenoid is energized by alternating (AC) ringing current, typically about at , it strikes the two gongs alternately, producing a distinctive effect of two superimposed sounds. In telephones with a ringer loudness control, one gong is mounted off-center on the loudness control wheel; turning the wheel moved the gong toward (quieter) or away (louder) from the striker. The model 500 ringer was fairly loud, and could be heard a few rooms away. The ringer could not be turned off on-the-fly, but could be disabled in the wiring.

P22TSP has also been studied due to its high kinetic stability. As it exists and functions in the extracellular environment, it must endure harsh conditions such as highly variable temperatures or high concentrations of protein degrading enzymes. The kinetic stability of P22TSP derives from its compact beta-solenoid architecture. It was shown that like other viral fibrous proteins, P22 tailspike protein possesses a high stability against denaturation.

Most electronic automatic transmissions utilize a TCC solenoid to regulate the torque converter electronically. Once fully locked, the torque converter no longer applies torque multiplication and will spin at the same speed as the engine. This provides a major increase in fuel economy. Modern designs provide partial lockup in lower gears to improve fuel economy further, but this can increase wear on the clutch components.

The ALE-39 countermeasures system uses intervalometers manufactured by Ledex Inc. (now part of Johnson Electric) of Dayton, Ohio. The ALE-39 fires flares in a synchronized pattern, rapidly and with great reliability. The intervalometer in the ALE-39 is essentially a solenoid-actuated rotary switch driven by a separate programmer, which gives timing intervals and channel enabling to either of one or two channels.

Alternating electric current flows through the solenoid, producing a changing magnetic field. This field causes an electric current to flow in a wire loop by electromagnetic induction. Magnetic fields can also be used to make electric currents. When a changing magnetic field is applied to a conductor, an electromotive force (EMF) is induced, which starts an electric current, when there is a suitable path.

In the simplest form of linear electric generator, a sliding magnet moves back and forth through a solenoid - a spool of copper wire. An alternating current is induced in the loops of wire by Faraday's law of induction each time the magnet slides through. This type of generator is used in the Faraday flashlight. Larger linear electricity generators are used in wave power schemes.

For a fusion reactor, the problem is keeping the plasma contained against this pressure; any known physical container would melt at these temperatures. A plasma is electrically conductive, and is subject to electric and magnetic fields. In a magnetic field, the electrons and nuclei orbit the magnetic field lines. A simple confinement system is a plasma-filled tube placed inside the open core of a solenoid.

Ironically some of the earlier ratcheting lap bar conversions use a solenoid release and can also produce a buzzing sound. It can be argued that single-position buzz bars give more air time on roller coasters, as ratcheting lap bars tend to lock further during the ride in many installations. The traditional "pirate ship" style thrill ride often utilizes this type of restraint, as does the Troika.

Standard wastegates have one port for attaching the boost control line from the charge air supply line or boost control solenoid. Recent advances in internal wastegate actuators bring dual port control. A dual port wastegate adds a second port on the opposite side of the actuator. Air pressure allowed to enter this second port aids the spring to push harder in the direction of closing the wastegate.

In 2000, a fuel system using unit injectors (called "Pumpe Düse" by Volkswagen) began to replace the distributor injection pump systems (except for the V8 engine, which used common rail design). In 2003, upgraded fuel injectors using a piezoelectric design began to replace the previous solenoid-operated unit injectors. Since 2009, most of the Volkswagen Group TDI engines have switched from unit injectors to common rail injection.

Bitter electromagnets are used where extremely strong fields are required. The iron cores used in conventional electromagnets saturate, and are limited to fields of about 2 teslas. Superconducting electromagnets can produce stronger magnetic fields but are limited to fields of 10 to 20 teslas, due to flux creep, though theoretical limits are higher. For stronger fields resistive solenoid electromagnets of the Bitter design are used.

After signals show the return to the stable zone, pressure is increased again. Past models used a piston for the control of the fluid pressure. Most recent models regulate the pressure by rapidly opening and closing solenoid valves. While the basic principle and architecture has been carried over from passenger car ABS, typical motorcycle characteristics have to be considered during the development and application processes.

An armadillo repeat is the name of a characteristic, repetitive amino acid sequence of about 40 residues in length that is found in many proteins. Proteins that contain armadillo repeats typically contain several tandemly repeated copies. Each armadillo repeat is composed of a pair of alpha helices that form a hairpin structure. Multiple copies of the repeat form what is known as an alpha solenoid structure.

Power (based on the 96-99 1.6 primera) is @ 6000 rpm. In Australia it was used in the Nissan Pulsar N14 and N15. A GA16DE was also released with the NVCS (Nissan Variable Cam [timing] System) solenoid, it carries the plastic rocker black valve cover with a different throttle body design which produced 115 hp (85 kW) @6400 rpm and 110 lb·ft (146 Nm) @4400 rpm.

The circulation flow rate to NICMOS was greatly reduced during this operating period confirming blockage in the circulation loop. Continued operation at reduced flow rates would limit NICMOS science so plans for purging and refilling the circulation system with clean neon gas were developed by NASA. The circulation loop is equipped with an extra neon tank and remotely operated solenoid valves for on-orbit purge-fill operations.

It is highly credible and validated with all we know, but it is not proven. It is only the best we have at this point in time. Another example of correct scientific reasoning is shown in the current search for the Higgs boson. Scientists on the Compact Muon Solenoid experiment at the Large Hadron Collider have conducted experiments yielding data suggesting the existence of the Higgs boson.

A live frog levitates inside a 32 mm diameter vertical bore of a Bitter solenoid in a magnetic field of about 16 teslas. A similar effect to gravity can be created through diamagnetism. It requires magnets with extremely powerful magnetic fields. Such devices have been able to levitate at most a small mouse, producing a 1 g field to cancel that of the Earth's.

Icemaker (for hotel customers) Automatic icemakers for the home were first offered by the Servel company around 1953. They are usually found inside the freezer compartment of a refrigerator. They produce crescent-shaped ice cubes from a metal mold. An electromechanical or electronic timer first opens a solenoid valve for a few seconds, allowing the mold to fill with water from the domestic cold water supply.

The fully electronic control is accomplished by the Transmission Control Module (TCM). Depending on year and application, it can either be a stand-alone module or integrated with the Powertrain Control Module (PCM). The TCM uses data from various transmission and engine sensors to control transmission shifting. The TCM operates the solenoid pack to change hydraulic flow through the valve body to various clutches in the transmission.

Commercially available nitrous oxide permitted, including for supercharged and turbocharged engines. Nitrous bottle(s) in driver compartment must be equipped with a relief valve and vented outside of driver's compartment. Bottle(s) must be stamped with a DOT-1800-pound rating and permanently mounted (no hose clamps or tie wraps). Hoses from bottle(s) to solenoid must be high-pressure steel- braided or NHRA-accepted hoses.

Aluminum 110-micron wires are strung across the chamber for field shaping. As a charged particle passes through the chamber the gas becomes ionized along the path of the particle and the ions drift to the nearest wires. The particles path will be curved because of the magnetic field the solenoid creates. The amount of curvature allows for the momentum of the particle to be calculated.

CLEO I NIM p. 51 The last CLEO I dedicated tracking chamber was the planar outer Z drift chamber (OZ) between the solenoid magnet and the dE/dx chambers. It consisted of three layers separated radially by 2.5 cm. The innermost layer was perpendicular to the beamline, and the outer two layers were at ±10° relative to the innermost chamber to provide some azimuthal tracking information.

The ANTH domain is a membrane binding domain that shows weak specificity for PtdIns(4,5)P2. It was found in AP180 (homologous to CALM) endocytotic accessory protein that has been implicated in the formation of clathrin-coated pits. The domain is involved in phosphatidylinositol 4,5-bisphosphate binding and is a universal adaptor for nucleation of clathrin coats. Its structure is a solenoid of 9 helices.

Before the common use of electronic clocks in automobiles, automobile clocks had mechanical movements, powered by an electric remontoire. A low power drive spring would be wound every few minutes by a plunger in a solenoid, powered by the vehicle's service battery and activated by a switch when the spring tension got too low. Such clocks were, however, notoriously inaccurate, typically being made as cheaply as possible.

|
To complete the loop, the card of magnets was placed on the other side of the twistor tape. Reads were performed by powering the solenoid to a point about half of that needed to produce a write. This field was "reflected" by the aluminum sheet, closing the loop, magnetically. The resulting field was greater than the write strength, causing the permalloy state to flip.

The twin-solenoid arrangement of the Shocker permitted slightly lower operating pressures to be used, however the drastically simpler arrangement of the Angel provided a faster firing sequence, which ultimately proved to be favored by the players and as a result the basic operating principle behind the Angel has remained unchanged (indeed, it has even been copied many times over by a series of "stacked tube electros"), whereas the Shocker has gone through a series of revisions that culminated in a complete redesign in 2003, and now uses a single solenoid powering the increasingly popular mechanical configuration known as a "spool bolt". It is also worth noting that while these two markers essentially tied for first electropneumatic markers to market, both designs were pre-dated (by years in some cases) by a series of homemade electropneumatic "kits" that modified pre-existing markers such as the Autococker or Sterling.

Moving iron speaker Moving iron sounder The moving iron speaker was the earliest type of electric loudspeaker. They are still used today in some miniature speakers where small size and low cost are more important than sound quality. A moving iron speaker consists of a ferrous-metal diaphragm or reed, a permanent magnet and a coil of insulated wire. The coil is wound around the permanent magnet to form a solenoid.

Rogovin, pp. 14–15. The design of the pilot-operated relief valve indicator light was fundamentally flawed. The bulb was simply connected in parallel with the valve solenoid, thus implying that the pilot-operated relief valve was shut when it went dark, without actually indicating the position of the valve. When the main relief valve stuck open, the unlighted lamp mislead the operators by implying that the valve was shut.

Once the general aspect had been finalised, this served as the template for a silicone rubber mould. This was coated with Bondaglass (fibreglass mixed with resin) and enhanced with Bondapaste, a putty-like substance, to accentuate contours.Marriott 1993, p. 171. The Bondaglass shell was then fitted with a solenoid, leather mouth parts and plastic eyes, as well as incisor teeth—a first for a Supermarionation production.Bentley 2005, pp. 10 and 16.

During the filming, dialogue was played into the studio using modified tape recorders that converted the feed into electronic pulses. Two of the wires relayed these pulses to the internal solenoid, completing the Supermarionation process. The wires, which were sprayed black to reduce their visibility, were made even less noticeable through the application of powder paint that matched the background colours of the set.Archer and Hearn, p. 114.

The tetratricopeptide repeat (TPR) is a structural motif. It consists of a degenerate 34 amino acid tandem repeat identified in a wide variety of proteins. It is found in tandem arrays of 3–16 motifs, which form scaffolds to mediate protein–protein interactions and often the assembly of multiprotein complexes. These alpha-helix pair repeats usually fold together to produce a single, linear solenoid domain called a TPR domain.
|
|
The Kelch motif is a region of protein sequence found widely in proteins from bacteria and eukaryotes. This sequence motif is composed of about 50 amino acid residues which form a structure of a four stranded beta-sheet "blade". This sequence motif is found in between five and eight tandem copies per protein which fold together to form a larger circular solenoid structure called a beta-propeller domain.

At first, the transmission included a three-speed gearbox with synchromesh on all forward ratios, controlled using a column-mounted lever. The option of Laycock-de-Normanville overdrive was announced at the end of 1949 and became available in June 1950, priced for UK buyers at slightly under £45 including purchase tax. Laycock overdrives were cable operated on top gear until 1954 when an electric solenoid was added.

Nose wheel steering is electronically controlled by the rudder pedals, utilizing the synchro principle. Hydraulic pressure for retraction and extension of the gear is transmitted by a system of tubing, hoses and actuating cylinders and is electrically controlled by limit switches and solenoid valves. Emergency extension can be accomplished pneumatically in case of hydraulic or electrical system failure. The main gear is enclosed by two doors after retraction.

The technician should then ensure that the marker is unloaded before firing several shots to blow out any remaining paint and dry out the interior. Replacements for broken parts should only be sourced from the manufacturer of the marker. Many guns also have elements not designed to be maintained by end users (such as solenoid valves); these should not be disassembled, and if they become faulty they are typically replaced outright.

Babun began his professional career manufacturing electrical components in Wisconsin and Connecticut. He founded General Electro-Components in 1980 to manufacture electrical relays and solenoids under the brand "Line Electric", serving as president and CEO. In 1981 he developed the TO-5, then known as "The World's Smallest Solenoid." In 1987 he moved back to South Florida in order to work for his father's company, Bahamas Line shipping company.

Designed to operate on low-pressure, The main operating pressure is 250–300 PSI, which can be monitored via the gauge on the primary (input) regulator. The secondary pressure is factory preset and regulated to 85–95 PSI. Gas usage is controlled through these 2 internal regulators. C02 is not a recommended propellant for the Promaster or any electropneumatic marker, as the cold liquid can destroy a solenoid valve.

When the reset button (3) is pressed, the contacts ((4) and another, hidden behind (5)) close, allowing current to pass. The solenoid (5) keeps the contacts closed when the reset button is released. The sense coil (6) is a differential current transformer which surrounds (but is not electrically connected to) the live and neutral conductors. In normal operation, all the current down the live conductor returns up the neutral conductor.

Test button RCDs can be tested with built-in test button to confirm functionality on a regular basis. RCDs may not operate correctly if wired improperly, so they are generally tested by the installer to verify correct operation. Use of a multifunction tester in the EU or a solenoid voltmeter in the USA. This introduces a controlled fault current from live to earth and measures the RCD operating time.

Inductance is the ability of an object to resist a change in current. From Ampère's law one can conclude that the magnetic field within a coil of wire (also called a solenoid) is constant inside the coil and zero outside the coil. This property is useful in circuits to store energy within a magnetic field. Inductors resist change in currents, therefore it will produce a current opposing the change.

This eliminates dive on heavy braking and drastically reduces squat on acceleration. The shock solenoids on all 4 struts and the solenoid on the ZF rack and pinion steering changes their behaviour (hard or soft) based on (independent) suspension sensors and ABS sensor based speed detection. The 1996 and 1997 models had sensors on all 4 wheels. The 1998 models only had sensors on the 2 front wheels.

An electromagnet, in its simplest form, is a wire that has been coiled into one or more loops, known as a solenoid. When electric current flows through the wire, a magnetic field is generated. It is concentrated near (and especially inside) the coil, and its field lines are very similar to those of a magnet. The orientation of this effective magnet is determined by the right hand rule.

Side view of porcine ribonuclease inhibitor;; ribbon is colored from blue (N-terminus) to red (C-terminus). RI is the classic leucine-rich repeat protein, consisting of alternating α-helices and β-strands along its backbone. These secondary structure elements wrap around in a curved, right-handed solenoid that resembles a horseshoe. The parallel β-strands and α-helices form the inner and outer wall of the horseshoe, respectively.

Pneumatic systems used in industry are commonly powered by compressed air or compressed inert gases. A centrally located and electrically powered compressor powers cylinders, air motors, and other pneumatic devices. A pneumatic system controlled through manual or automatic solenoid valves is selected when it provides a lower cost, more flexible, or safer alternative to electric motors and actuators. Pneumatics also has applications in dentistry, construction, mining, and other areas.

This instrument used an electromagnetic solenoid coil to draw an iron rod into its hollow interior. The rod's displacement opened a switch that stopped current from flowing in the coil; then being unattracted, the rod reverted out of the coil, and this cycle repeated again. The resulting reciprocating motion of the rod back and forth, into and out of the coil, was converted to rotary motion by the mechanism.

Rear view of tape transport. Two bronze flywheels in the bottom are capstan motor rotors. Above them is the solenoid that lifts the head subchassis (center) and its hydraulic damper (left, black) The B215, like all B-series Revoxes, is larger than the typical hi-fi component of the period. The enclosure measures and is a standard Studer pressed steel box with two internal stiffener rails that carry the tape transport.

Some displays use the other end of the solenoid to actuate a reed switch, which controls an LED array behind the disc, resulting in a display that is visible at night but requires no extra drive electronics. Various driving schemes are in use. Their basic purpose is to reduce the amount of wiring and electronics needed to drive the solenoids. All common methods connect the solenoids in some sort of matrix.

The new electromagnetic calorimeter used 7784 CsI crystals doped with thallium. Each crystal was roughly 30 cm deep and had a 5 cm × 5 cm face. The central region of the calorimeter was a cylinder placed between the drift chamber and the solenoid magnet, and two endcap calorimeters were placed at either end of the drift chamber. The crystals in the endcap were oriented parallel to the beam line.

The Planet Eclipse Ego, an electropneumatic paintball marker In electromagnetic designs, the trigger, instead of being mechanically linked to the action of the marker, simply activates an electronic micro-switch (or more recently, a magnetic or optical sensor). That information is passed through control circuitry to a computer-controlled solenoid valve which can open and close very quickly and precisely, allowing gas to move into or out of various pressure chambers in the marker to move the bolt and fire the paintball. This disconnect of the trigger from the action allows electronic trigger pulls to be very short in length and very lightweight (similar to a mouse click; the mechanisms are virtually identical), which dramatically increases rate-of-fire over a fully mechanical design. Solenoid-controlled gas valve designs also allow for reduced weight of internal parts, which both lightens overall weight and reduces the time it takes for the marker to cycle through firing a single paintball.

Animated cut through diagram of a typical fuel injector (click to see animation) Delphi E1 UI on the Volvo D13A engine Delphi E1 unit injector parts The basic operation can be described as a sequence of four separate phases: the filling phase, the spill phase, the injection phase, and the pressure reduction phase. A low pressure fuel delivery pump supplies filtered diesel fuel into the cylinder head fuel ducts, and into each injector fuel port of constant stroke pump plunger injector, which is overhead camshaft operated. ;Fill phase: The constant stroke pump element on the way up draws fuel from the supply duct in to the chamber, and as long as electric solenoid valve remains de-energized fuel line is open. ;Spill phase: The pump element is on the way down, and as long as solenoid valve remains de-energized the fuel line is open and fuel flows in through into the return duct.

The second mark (changeover cue) would alert the projectionist that the changeover was imminent, and one full second after the mark he would trigger a solenoid that would open the incoming projector and another solenoid that would close the outgoing projector. The audio would be switched at this time as well; the audio for a particular film frame appears 20 frames (about 15 inches) before the image, and so all film prints carry the first two to three feet of audio of the reel they precede at their tail, called a sound pullup (digital systems use different offsets before or after the image, which a computer corrects for). Film prints could be prepped by a projectionist with automatic changeover cues, which were small metallic appliqués which could be applied to a print at the first cue mark. Readers attached to the projector would read the marks and execute the changeover sequence automatically, as long as the incoming reel was threaded properly on the second projector.

The M60C was adopted for use on fixed mounts on aircraft. It was characterized by the use of an electric solenoid to operate the trigger and a hydraulic system to charge the weapon. The M60D differed from the base model by employing spade grips, a different sighting system, and lacking a forearm. It was typically employed as a door gun on helicopters or as a pintle-mounted weapon as on the Type 88 K1 tank.

Trent successfully destroys the mirror and recovers the missing fingers, one by one. When the computer is whole, he learns the terrible truth: he is not a man, but a robot. The human survivors have been digitally encoded onto a gold-copper alloy wire wrapped around the solenoid in his thorax. Immune to disease, he must protect his precious cargo for 1,200 years, after the Kyben invasion, by which time the plague will have dissipated.

Pop bumpers are operated by a switch connected to a ring surrounding the bottom circumference of the bumper that is suspended several millimeters above the playfield surface. When the ball rolls over this ring and forces one side of it down, a switch is closed that activates the bumper's solenoid. This pulls down a tapered ring surrounding the central post of the bumper that pushes downward and outward on the ball, propelling it away.

Non-electronic markers sometimes use carefully set pneumatic to achieve a light and short trigger pull. The trigger frame on non-electronic mechanical markers simply use a series of springs and levers to drop a sear, which propels the hammer in the body forward. On electronic markers, the trigger frame houses the electronics that control the solenoid, as well as features such as ball detection systems. Upgraded circuit boards that add improved features are available.
|
|
Instead of the spring and hammer used to actuate the valve and cycle the bolt assembly in mechanical markers, electropneumatic markers use the rerouting of air to different locations in the marker. This rerouting is controlled by a solenoid that is activated by the trigger. The two types of bolt and valve mechanisms in electropneumatic markers are the poppet-valve and spool-valve. Poppet-valve-based electropneumatic markers are very similar to mechanical blowback markers.

GEM Systems Inc., 11 January 2010. A direct current flowing in a solenoid creates a strong magnetic field around a hydrogen-rich fluid (kerosene and decane are popular, and even water can be used), causing some of the protons to align themselves with that field. The current is then interrupted, and as protons realign themselves with the ambient magnetic field, they precess at a frequency that is directly proportional to the magnetic field.

An ALS requires an air bypass, generally done in one of two ways. The first method is to use a throttle air bypass; this may be an external bypass valve or a solenoid valve which opens the throttle 12-20 degrees. This allows air to bypass the closed throttle and to reach the engine. The second method is to use a bypass valve that feeds charge air directly to the exhaust manifold.
|
|
The mass air flow sensor measures the amount of air flowing into the engine through the throttle plate. The engine coolant temperature sensor measures whether the engine is warmed up or cool. If the engine is still cool, additional fuel will be injected. Air–fuel mixture control of carburetors with computers is designed with a similar principle, but a mixture control solenoid or stepper motor is incorporated in the float bowl of the carburetor.

Stoner 63 rifle Stoner left ArmaLite in 1961 to serve as a consultant for Colt. He eventually accepted a position with Cadillac Gage where he designed the Stoner 63 Weapons System. This was a modular weapons system which could be reconfigured to be a standard automatic rifle, a light machine gun, a medium machine gun, or a solenoid-fired fixed machine gun. The Stoner Weapons System used a piston-operated gas impingement system.

A heavily smoked perspex nose allowed the stuntman sufficient visibility to steer the device whilst being entirely hidden from view. A pincer type lock held the sidecar in place until operated by the pilot via a solenoid switch. The sequences involving the outfit were speeded up as the weight of the sidecar made the outfit very difficult to control. In October, the second unit travelled to Nassau to film the underwater sequences.

The CODATA recommended value is CODATA refers to this as the electron charge-to-mass quotient, but ratio is still commonly used. There are two other common ways of measuring the charge-to-mass ratio of an electron, apart from Thomson and Dunnington's methods. #The magnetron method: Using a GRD7 Valve (Ferranti valve), electrons are expelled from a hot tungsten-wire filament towards an anode. The electron is then deflected using a solenoid.

Combinations of electrical control of fluid power elements are widespread in automated systems. A wide variety of measuring, sensing, or control elements are available in electrical form. These can be used to operate solenoid valves or servo valves that control the fluid power element. Electrical control may be used to allow, for example, remote control of a fluid power system without running long control lines to a remotely located manual control valve.

Wear and tear also places considerable strain on the vacuum system's vulnerable pump, its 11 solenoid valves and its relays. Finally, the barometer needs to be exclusively filled with pure rainwater, as tap water contains many minerals which may be detrimental to the barometer.A Handbook for the Water Barometer, The Denmark Visitor Centre, 11.12.2008. Because the water barometer has always been treated with great care, the instrument still looks almost new despite its age.

There are also pneumatic drum brakes,Andersen & Kjenstad: 132 although they are only used for parking, braking form the back end and for a passenger-induced emergency brake. The MO units were instead equipped with clasp brakes controlled by pneumatics. Trailers were equipped with solenoid brakes, but lacked a parking brake as it was found that the motor unit's holding brake was sufficient.,Andersen & Kjenstad: 134 In addition all units had an emergency rail brake.

Chromatin was first discovered by Walther Flemming by using aniline dyes to stain it. In 1974, it was first proposed by Roger Kornberg that chromatin was based on a repeating unit of a histone octamer and around 200 base pairs of DNA. The solenoid model was first proposed by John Finch and Aaron Klug in 1976. They used electron microscopy images and X-ray diffraction patterns to determine their model of the structure.

Solenoid voltmeters are extremely rugged and not very susceptible to damage through either rough handling or electrical overload. For "go/no go" testing, there is no need to read the scale as application of AC power creates a perceivable vibration and sound within the meter. This feature makes the tester very handy in noisy, poorly illuminated, or very bright surroundings. The meter can be felt, the more it jumps the higher the voltage.

Pontiac Trans Am burnout with line locks. A line lock is a device that allows the front brakes to lock independently of the rear brakes via a switch. The device is an electric solenoid that controls a valve which allows the brakes to be controlled individually. This allows the front brakes to be locked and the rear brakes to be open, and allows the driver to spin the rear wheels without wasting the rear brakes.

Wiring should be similar in size to the wiring to the vehicle engine starter motor. Mechanical vehicle mounted devices usually have an electric brake, a solenoid that presses a friction pad against the siren rotor. When an emergency vehicle arrives on-scene or is cancelled en route, the operator can rapidly stop the siren. Multi-speaker electronic sirens often are alleged to have dead spots at certain angles to the vehicle's direction of travel.

Sakharov then tested a MK-driven "plasma cannon" where a small aluminum ring was vaporized by huge eddy currents into a stable, self-confined toroidal plasmoid and was accelerated to 100 km/s. Sakharov later suggested replacing the copper coil in MK generators with a large superconductor solenoid to magnetically compress and focus underground nuclear explosions into a shaped charge effect. He theorized this could focus 1023 protons per second on a 1 mm2 surface.

However the company was some thirty years too early as demand for air conditioned cars in Europe did not materialise; the company withdrew from the market in 1964. In 1960, further agreements with Bendix brought licensed production of hydraulic servo valves to Normalair's range of products. This expertise was then developed for electro-hydraulic servo valves, actuators and lightweight solenoid-operated hydraulic valves. The company also produced marine hydraulics and valves for submarines.

The Mark 19 torpedo was an electric torpedo designed in 1942 by Westinghouse Electric as a follow-on development of the Mark 18 torpedo. The goal was to build a torpedo that incorporated all-electric controls in place of pneumatic controls. Its gyroscope and depth control were electrically controlled and operated, while the rudders were solenoid operated. Further development of the Mark 19 was cancelled in favor of the Mark 26 torpedo.

The P8 was supplied with engine mountings. The electrical system was powered by a 12 volt, lightweight, aircraft battery, which had a master battery control. It powered a starter solenoid via starter button and switches, as well as an array of instruments, including tachometer (0–10,000 rpm), oil pressure, water temperature, and oil temperature. All suspension parts were in new Bowin Satin finish, and the other parts were cadmium-plated and stove-enamelled.

The . bipod-mounted version was marketed as a light machine gun for use by assault troops. It was the only version with a buttstock. The . tripod-mounted version was considered a medium machine gun. The vehicle mounted version was a pintle- mounted machine gun for use by soldiers in land vehicles. The fixed mount version was fired by a solenoid allowing for remote operation so it could be mounted in a helicopter or other aircraft.

The four phases of EUI operation are: ; Fill phase: As the pump plunger retracts, fuel is drawn into the pump chamber from the fuel supply line. ; Spill phase: The pump plunger begins descending, but the spill valve is open, and fuel recirculates back to the return line. ; Injection phase: Partway through the pump stroke, the solenoid is energized, which closes the spill valve. The fuel is forced into the cylinder through the spray tip.

The rods are slowly burnt away in use, and the distance between them needs to be regularly adjusted in order to maintain the arc. Many ingenious mechanisms were invented to affect the distance automatically, mostly based on solenoids. In one of the simplest mechanically-regulated forms (which was soon superseded by more smoothly acting devices) the electrodes are mounted vertically. The current supplying the arc is passed in series through a solenoid attached to the top electrode.
|
|
If the points of the electrodes are touching (as in start up) the resistance falls, the current increases and the increased pull from the solenoid draws the points apart. If the arc starts to fail the current drops and the points close up again. The Yablochkov candle is a simple arc lamp without a regulator, but it has the drawbacks that the arc cannot be restarted (single use) and a limited lifetime of only a few hours.

Among others, involvement took place in the development of standards related to the 4–20 mA current loop, NAMUR sensors (e.g., IEC 60947-5-6]), NAMUR solenoid mounting plates (VDI/VDE 3845, ISO 5211), and Profibus. The exchange of experience about the equipment used in the member companies has been an important aspect of the association's activities from the very beginning. Membership in NAMUR was originally restricted to companies in the chemical, pharmaceutical and petrochemical industries.

Most proteins that contain the motif have four to six repeats, although its namesake ankyrin contains 24, and the largest known number of repeats is 34, predicted in a protein expressed by Giardia lamblia. Ankyrin repeats typically fold together to form a single, linear solenoid structure called ankyrin repeat domains. These domains are one of the most common protein–protein interaction platforms in nature. They occur in a large number of functionally diverse proteins, mainly from eukaryotes.

Only when air evacuation is complete does the discharge stop. Flow is usually controlled by a steam trap or a solenoid valve, but bleed holes are sometimes used. As the steam and air mix, it is also possible to force out the mixture from locations in the chamber other than the bottom. Steam pulsing: air dilution by using a series of steam pulses, in which the chamber is alternately pressurized and then depressurized to near atmospheric pressure.

Alternatively, an electro-mechanical oscillator driven by an AC-energized solenoid may be used. Some very early mechanical shavers had no electric motor and had to be powered by hand, for example by pulling a cord to drive a flywheel. The first electric razor was invented by John F. O’Rourke in 1898. Industrial production of electric razor machines started in 1937 by the US company Remington Rand based on the patent of Jacob Schick from 1928.

Alternating electric current flows through the solenoid on the left, producing a changing magnetic field. This field causes, by electromagnetic induction, an electric current to flow in the wire loop on the right. Electromagnetic or magnetic induction is the production of an electromotive force across an electrical conductor in a changing magnetic field. Michael Faraday is generally credited with the discovery of induction in 1831, and James Clerk Maxwell mathematically described it as Faraday's law of induction.

The single loop antenna was replaced by two antennas, arranged at right angles. The output of each was sent to its own looped wire, or as they are referred to in this system, a "field coil". Two such coils, one for each antenna, are arranged close together at right angles. The signals from the two antennas generated a magnetic field in the space between the coils, which was picked up by a rotating solenoid, the "search coil".

Sphicas continued work on the CDF through the 1990s as part of MIT's team in the CDF experiments. The MIT Team was responsible for three Collider components: the forward calorimeter, the Data Acquisition System and the Third Level Trigger. The 18 MIT scientists, by then led by Sphicas, were part of the team that produced the first evidence for the Top quark in 1994. Sphicas began participating in the Compact Muon Solenoid (CMS) experiment at CERN in 1994.

Utilizing "normally closed" solenoid valve significantly reduces energy consumption by preventing siphoning of non-hot water out of hot water lines during cold water use. Using cold water instantly lowers the water pressure in the cold water lines, the higher water pressure in the hot water lines force water through "normally open" thermostatic crossover valves and backflow check valves (which only prevent cold water from flowing into hot water line), increasing the energy demand on the water heater.

The expense of building multiple necks on the same instrument made them unaffordable for most players, and a more sophisticated solution was needed. At this point, the goal was simply to create a pedal that would change the pitch of all the strings at once to emulate a second neck. In 1939, a guitar called the "Electradaire" featured a pedal controlling a solenoid, triggering an electrical apparatus to change the tension on the strings. This was not successful.

A coaxially- mounted stockless electric solenoid-fired variant was developed under the designation SGMT (the "T" standing for Tankovy, or "Tank"). The SG-43M and SGMB are versions modified with dust covers and used mostly on armoured personnel carriers. The SG-43/SGM was widely exported and also licensed for construction in several countries. It was manufactured in the People's Republic of China as the Type 53 (SG-43) and Type 57 (SGM) heavy machine guns.

The vacuum pump cycle became shorter than it was in the Netherlands; reduced to six minutes from the previous ten. The timer relays had been replaced by a PLC, which now governs a refined and modernized vacuum system with 11 solenoid valves. Operating eight hours per day, seven days a week, the water barometer was constantly ‘on the move’. Visitors could walk up the stairs and take a reading in the Reading Room atop the Tower.

Bitter joined the Department of Mining and Metallurgy as an associate professor in 1934. (The department is now known as Materials Science and Engineering.) While at MIT, he developed the Bitter electromagnet which was/is the most powerful electromagnet design. He established a magnet laboratory in 1938, where he built a solenoid magnet that produced a constant field of 100,000 gauss (10 teslas). He also did work in the first characterization of the Zeeman effect with George Harrison.

A "horseshoe magnet" made of alnico, an iron alloy. The magnet, made in the shape of a horseshoe, has the two magnetic poles close together. This shape creates a strong magnetic field between the poles, allowing the magnet to pick up a heavy piece of iron. Magnetic field lines of a solenoid electromagnet, which are similar to a bar magnet as illustrated below with the iron filings A magnet is a material or object that produces a magnetic field.

Sometimes an attachment has more features than your forklift has hydraulic functions and one or more need to be added. There are many ways of adding hydraulic functions (also known as adding a valve). The forklift manufacturer makes valves and hose routing accessories, but the parts and labor to install can be prohibitively expensive. Other ways include adding a solenoid valve in conjunction with a hose or cable reel that diverts oil flow from an existing function.

They first appeared in the 1900s, when they were actuated either mechanically or pneumatically. In 1908, Alfredo Barrachini in Rome added electric lights inside the arms that turned on as they extended, but operation was still by a cable system. Electric operation came in 1918 when the Naillik Motor Signal Company of Boston added electric motor drive. This system was superseded by two French inventors, Gustave Deneef and Maurice Boisson, who used a linear solenoid in 1923.

This type is the most economic and basic type of semi-active suspensions. They consist of a solenoid valve which alters the flow of the hydraulic medium inside the shock absorber, therefore changing the damping characteristics of the suspension setup. The solenoids are wired to the controlling computer, which sends them commands depending on the control algorithm (usually the so-called "Sky-Hook" technique). This type of system is used in Cadillac's Computer Command Ride (CCR) suspension system.

This allowed the transmission to be lightweight and to use fewer moving parts than the three speed it replaced. The 41TE transmission which directly replaced the TorqueFlite had a similar design and could be considered an evolutionary change, but it included different valve bodies, solenoid packs, sensors, and other components to increase reliability. This line was also given a flash- programmable TCM and, in 2006, a variable line pressure hydraulic system was phased in, which boosted performance and longevity.

The placement of the lip-sync mechanism dictated the puppets' body proportions.La Rivière 2009, p. 150. For all Supermarionation series up to Thunderbirds, the solenoid was located in the head. This meant that the head was oversized in relation to the rest of the body; the latter could not be scaled up to match as this would have made the puppets too bulky to operate effectively, besides requiring all of the set elements to be enlarged accordingly.

The vacuum flowed through the switch to a vacuum solenoid (such as a heat riser, used to restrict exhaust allowing the engine to heat up faster). When the coolant heated to operating temperature the vacuum switch closed off the port (port S on the vacuum switch) turning off the vacuum to the heat riser. The result is to clear the exhaust restriction. The switch monitored the temperature and when conditions were right it performed its designed function.

The operation of the Bushmaster 2000 is very similar to that of the Impulse, Intimidator or other poppet-valve based electropneumatic markers. The marker is classified as open-bolt, meaning the bolt is in the full-back position before the firing sequence. When the trigger is pulled, an electronic microswitch sends a signal to the marker's electronic board telling it to begin the firing sequence. The board then actuates the solenoid which is provided with air from the LPR.

These flaps allowed for the power- training equipment to be serviced easily. The mount was supplied from the ship's main supply, at direct current. This current powered the trigger circuit solenoid, the permanent and peak output training and elevating motors, and the moveable auxiliary lighting of the mount. The lights for the gun sights, the control positions, the breech, and the firing warning system (flashing blue and red lights, alongside a buzzer), were all powered by a transformer.

As the particles are moving at high speed, their resulting paths look like a helix. If one arranges a magnetic field so lines of force are parallel and close together, the particles orbiting adjacent lines may collide, and fuse. Such a field can be created in a solenoid, a cylinder with magnets wrapped around the outside. The combined fields of the magnets create a set of parallel magnetic lines running down the length of the cylinder.
|
|
When the armature reaches the extreme of its movement, polarity to the coils is reversed. The armature may instead be made of ferromagnetic material, as in an electromagnetic solenoid. In this case the current in the coils will alternate between on and off, rather than between polarities. A single-coil motor with a non-magnetic armature would require a spring or some other "return" mechanism to move the armature away from the coil upon completion of the "attract" cycle.
|
|
This makes their direct acting use commonly limited to low actuating forces. Often, a low power solenoid valve is used to operate a small hydraulic valve (called the pilot) that starts a flow of fluid that drives a larger hydraulic valve that requires more force. A bi-stable pneumatic valve is typically a pilot valve that is a 3 ported 2 position detented valve. The valve retains its position during loss of power, hence the bi-stable name.
|
|
The original transmissions were a 4-speed non-synchronized manual transmission with solenoid reverse. Late in production, an Allison automatic version was offered. The 4107 and 4903 models were notorious for being difficult to shift gears, routinely making loud, grinding noises which tended to upset the passengers. Double-clutching reduced these embarrassing noises, but even the most skilled driver would occasionally have problems, especially when changing buses (or powertrains) meant an unfamiliar feel to clutch and shifter.

At about 2500RPM and further the engine is able to switch to the 16-valve mode, which is usual to the classic engines. The first VTEC solenoid is opened and directs the oil to the sliding pin that connects the rocker arms of the intake valves with the first intake valve's lobe. Thus all the two intake valves are moving at the normal profile of that lobe. The engine's performance is usual to the non-VTEC engines.

For energy production purposes, one might use a container located inside a solenoid. The container is filled with gaseous uranium hexafluoride, where the uranium is enriched, to a level just short of criticality. Afterward, the uranium hexafluoride is compressed by external means, thus initiating a nuclear chain reaction and a great amount of heat, which in turn causes an expansion of the uranium hexafluoride. Since the UF6 is contained within the vessel, it can't escape and thus compresses elsewhere.
|
|
The result is a plasma wave moving in the container, and the solenoid converts some of its energy into electricity at an efficiency level of about 20%. In addition, the container must be cooled, and one can extract energy from the coolant by passing it through a heat exchanger and turbine system as in an ordinary thermal power plant. However, there are enormous problems with corrosion during this arrangement, as the uranium hexafluoride is chemically very reactive.

C. Historic American Buildings Survey (HABS) Angels Flight; c. 1905, View with the Third Street Tunnel and an observation tower Records indicate that the emergency brake had been inoperative for 17 to 26 months due to the fact that a normally closed hydraulic solenoid valve had been placed in a location where the design called for a normally open valve and that its ill fitted solenoid was burned out. During the 17 to 26 months that the emergency braking system was not operating, the braking system was tested daily, but since the service brake and emergency brake were tested simultaneously, there was no way to tell if the emergency brake was functioning without looking at the brake pads or hydraulic pressure gauges during the test. The test was always performed with the Sinai car traveling uphill, which meant that when the power was cut and the brakes applied (as part of the test), Sinais momentum caused the car to continue moving uphill a short distance (slackening the cable) and then to roll back from gravity, jerking the cable tight.

If no electricity comes in on the normal side, the transfer switch uses a solenoid to throw a triple pole, single throw switch. This switches the feed from normal to emergency power. The loss of normal power also triggers a battery operated starter system to start the generator, similar to using a car battery to start an engine. Once the transfer switch is switched and the generator starts, the building's emergency power comes back on (after going off when normal power was lost).

Design of the ST40 spherical tokamak with a major radius of 0.4 m. Tokamak reactors consist of a toroidal vacuum tube surrounded by a series of magnets. One set of magnets is logically wired in a series of rings around the outside of the tube, but are physically connected through a common conductor in the center. The central column is also normally used to house the solenoid that forms the inductive loop for the ohmic heating system (and pinch current).

In 1989, he became an adjunct professor of physics at the University of California, Los Angeles, and he became an adjunct professor at the University of Texas at Dallas in 1990. He began working on cancer research at the University of California, Irvine in 1996. Beginning in 1995, Atac worked on developing a Silicon Pixels Vertex Tracking System for the Compact Muon Solenoid (CMS) experiment at CERN's Large Hadron Collider.

Under Lee's direction, the business was transformed "from a small machine shop in western New York to a global enterprise," according to The New York Times. In 2003, Lee became Automation Group President of International Motion Control (IMC) of Erie County, another company founded by his father. The Automation Group companies initially included Enidine Industrial Products, Enidine Germany, Enidine Japan, Compact Automation Products, Midland Pneumatics and JPI Korea. He oversaw the group's acquisition of the solenoid valve firm Evolutionary Concepts Inc.

WD40 repeat domain of beta-TrCP (green), leucine-rich repeat domain of TLR2 (red), armadillo repeat domain of beta-catenin (blue), ankyrin repeat domain of ANKRA2 (orange), kelch repeat domain of Keap1 (yellow) and HEAT repeat domain of a PP2A regulatory subunit R1a (magenta). Solenoid protein domains are a highly modular type of protein domain. They consist of a chain of nearly identical folds, often simply called tandem repeats. They are extremely common among all types of proteins, though exact figures are unknown.

In some top loaders, the motor runs only in one direction. During agitation, the transmission converts the rotation into the alternating motion driving the agitator. During the spin cycle, the timer turns on a solenoid which engages a clutch locking the motor's rotation to the wash basket, providing a spin cycle. General Electric's very popular line of Filter-Flo (seen to the right) used a variant of this design where the motor reversed only to pump water out of the machine.

Electromechanical protective relays operate by either magnetic attraction, or magnetic induction. Unlike switching type electromechanical relays with fixed and usually ill-defined operating voltage thresholds and operating times, protective relays have well-established, selectable, and adjustable time and current (or other operating parameter) operating characteristics. Protection relays may use arrays of induction disks, shaded-pole, magnets, operating and restraint coils, solenoid-type operators, telephone-relay contacts, and phase- shifting networks. Protective relays can also be classified by the type of measurement they make.

No laser or optical sight has yet been selected for use on the K12, but some kind of electro- optical accessories are expected in the near future. In 2015, S&T; Motiv unveiled the XK-12C1, a coaxial machine gun version of the K12 with a heavier barrel and solenoid trigger. It is designed to fill the role of the M60C coaxial gun mounted on many vehicles, as they are nearing their operational age limit and will soon need replacement.ADEX 2015 - SAdefensejournal.

A team of UF physicists has a leading role in one of the two major experiments planned for the Large Hadron Collider, a -long, $5 billion, super-cooled tunnel outside Geneva, Switzerland. More than 30 university physicists, postdoctoral associates, graduate students and now undergraduates are involved in the collider's Compact Muon Solenoid (CMS) experiment, one of its two major experiments. About 10 are stationed in Geneva. The group is the largest from any university in the U.S. to participate in the CMS experiment.

Critical user interface engineering problems were revealed in the investigation of the reactor control system's user interface. Despite the valve being stuck open, a light on the control panel ostensibly indicated that the valve was closed. In fact, the light did not indicate the position of the valve, only the status of the solenoid being powered or not, thus giving false evidence of a closed valve. As a result, the operators did not correctly diagnose the problem for several hours.

The structure of the PP5 protein was the first structure to be determined. The structure solved by X-ray crystallography by Das and colleagues showed that the TPR sequence motif was composed of a pair of antiparallel alpha helices. The PP5 structure contained 3 tandem TPR repeats which showed the sequential TPR repeats formed an alpha- helical solenoid structure. A typical TPR structure is characterized by interactions between helices A and B of the first motif and helix A’ of the next TPR.

Luray Caverns, originally called Luray Cave, is a cave just west of Luray, Virginia, United States, which has drawn many visitors since its discovery in 1878. The cavern system is generously adorned with speleothems such as columns, mud flows, stalactites, stalagmites, flowstone, and mirrored pools. The caverns are perhaps best known for the Great Stalacpipe Organ, a lithophone made from solenoid-fired strikers that tap stalactites of various sizes to produce tones similar to those of xylophones, tuning forks, or bells.

The print-head and daisy wheel on a Xerox/Diablo D-25 printer. The heart of the system is an interchangeable metal or plastic "daisy wheel" holding an entire character set as raised characters moulded on each "petal". In use a servo motor rotates the daisy wheel to position the required character between the hammer and the ribbon. The solenoid-operated hammer then fires, driving the character type onto the ribbon and paper to print the character on the paper.

Finch and Klug actually observed a wide range of nucleosomes per turn but they put this down to flattening. Finch and Klug's electron microscopy images had a lack of visible detail so they were unable to determine helical parameters other than the pitch. More recent electron microscopy images have been able to define the dimensions of solenoid structures and identified it as a left-handed helix. The structure of solenoids are insensitive to changes in the length of the linker DNA.

Further displacement sensors record the travel distance of the piston to allow the control unit a more precise regulation. Honda also uses this system of pressure modulation for big sports and touring bikes. Valve and Pump Systems: The main parts which are part of the pressure modulation system are solenoid inlet and outlet valves, a pump, motor and accumulators/reservoirs. The number of the valves differs from model to model due to additional functionalities and the number of brake channels.

The fuel injector valves are of a solenoid type with needle and seat. They are opened by a current flowing through the injector's coil and are closed by a strong spring when the current is switched off. To ensure as optimal combustion as possible and with that lower exhaust emission the injectors are equipped with four holes, which gives a good distribution of the fuel. The squirts of fuel are very exact positioned (two jets on the backside on each inlet valve).

It acquired the Jucker Industrial Division, an Italian controls business, in 1993, Bredel Hose Pumps, a business manufacturing high-pressure hose pumps, in 1996 and M&M; International, an Italian piston actuated and solenoid valve business in 2001. In September 2005 it acquired Mitech Actuators & Controls and Proportional Control Technology, a pair of South African businesses making process controls. Then later that year it bought EMCO Flow Systems, a metering business. The company acquired Intervalf, a Turkish operation, for £2.8m in 2009.

The higher the curvature, the lower the momentum and vice versa. Because the particles have such a high energy, a very strong magnet is needed to bend the paths of the particles. The solenoid is a superconducting magnet cooled by liquid helium. The helium lowers the temperature of the magnet to 4.7 K or -268.45 °C which reduces the resistance to almost zero, allowing the magnet to conduct high currents with minimal heating and very high efficiency, and creating a powerful magnetic field.

A siren with only one row of ports is called a single tone siren. A siren with two rows of ports is known as a dual tone siren. By placing a second stator over the main stator and attaching a solenoid to it, one can repeatedly close and open all of the stator ports thus creating a tone called a pulse. If this is done while the siren is wailing (rather than sounding a steady tone) then it is called a pulse wail.

A live frog levitates inside a diameter vertical bore of a Bitter solenoid in a magnetic field of about 16 teslas at the Nijmegen High Field Magnet Laboratory. Diamagnets may be levitated in stable equilibrium in a magnetic field, with no power consumption. Earnshaw's theorem seems to preclude the possibility of static magnetic levitation. However, Earnshaw's theorem applies only to objects with positive susceptibilities, such as ferromagnets (which have a permanent positive moment) and paramagnets (which induce a positive moment).

The energy of the progenitor particle was shared among many shower particles of much lower energy that ultimately stopped, at which point the shower ended. Between the layers of the inert material there were detectors in which the ionization of the particles was measured. The total ionization signal summed over the shower is proportional to the energy of the progenitor particle. A cylindrical layer of scintillator- based preshower strips was placed immediately outside the solenoid and read out with fiber tracker sensors.

It offers a docking position for another 19S subunit Rpn10 at its central solenoid portion, although such association with Rpn10 is stabilized by a third subunit, Rpn2. Besides its critical roles in 19S complex assembly, Rpn2 also provides docking positions for shuttles of ubiqitinylated substrate trafficking. The majority of shuttles attach to the proteasome via a ubiquitin-like domain (UBL) while they unload the substrate cargo at a C-terminal polyubiquitin-binding domain(s).

The different types and sizes of Garrett's turbochargers. Garrett offers gasoline-powered turbochargers called wastegate turbos. They are designed to be smaller than previous turbo generations, have higher fuel efficiency, more torque, and meet emissions standards. Garrett also offers Variable-geometry turbochargers called VNT. They have nine moveable vanes, an electrohydraulic actuator and a proportional solenoid for variable control throughout the engine’s power curve. This means the air passageway of the turbo varies to meet the engine’s needs at different RPMs.

Positively charged ions and negatively charged electrons in a fusion plasma are at very high temperatures, and have correspondingly large velocities. In order to maintain the fusion process, particles from the hot plasma must be confined in the central region, or the plasma will rapidly cool. Magnetic confinement fusion devices exploit the fact that charged particles in a magnetic field experience a Lorentz force and follow helical paths along the field lines. The simplest magnetic confinement system is a solenoid.

It was planned for JT-60 to be disassembled and then upgraded to JT-60SA by adding niobium- titanium superconducting coils by 2010. lots of detail on JT-60SA in section 3 It is intended to be able to run with the same shape plasma as ITER. The central solenoid will use niobium-tin (because of the higher (9 T) field). Construction of the tokamak officially began in 2013, and will continue until 2020 with first plasma planned in September 2020.

Such long repeats are frequently indicative of the presence of a solenoid domain in the protein. Approximately half of the tandem repeat regions have intrinsically disordered conformation being naturally unfolded. Examples of disordered repetitive sequences include the 7-mer peptide repeats found in the RPB1 subunit of RNA polymerase II, or the tandem beta-catenin or axin binding linear motifs in APC (adenomatous polyposis coli). The other half of the regions with the stable 3D structure has a plethora of shapes and functions.

1980 Chevrolet Camaro RS For 1980 the aged inline- six was replaced with a V6 engine, in California, a first for Camaro. The (4.4 L) 267 cu in V8 engine became an option on the base, RS and Berlinetta models this year. The Z28 hood included a rear-pointing raised scoop (air induction) with a solenoid operated flap which opened at full throttle, allowing the engine to breathe cooler air. A federally mandated speedometer also debuted this year, down from 130.

During the primary turbo stage, boost pressure is controlled by a conventional arrangement of an ECU-controlled duty-cycle solenoid and an internal wastegate. The secondary turbo remains inoperative during this stage, as a separate exhaust control valve (situated on the right side of the engine) remains closed. This valve prevents exhaust gasses entering the secondary turbine. During the 4000–4500 rpm transitional stage, however, the exhaust control valve is partially opened, bringing the secondary turbo up to near- operating speed.

The presence of a magnetic toroidic dipole moment T in condensed matter is due to the presence of a magnetoelectric effect: Application of a magnetic field H in the plane of a toroidal solenoid leads via the Lorentz force to an accumulation of current loops and thus to an electric polarization perpendicular to both T and H. The resulting polarization has the form Pi = εijkTjHk (with ε being the Levi- Civita symbol). The resulting magnetoelectric tensor describing the cross- correlated response is thus antisymmetric.

Y-K Martin Peng, "Compact DT Fusion Spherical Tori at Modest Fields", CONF-850610-37 (December 1985) The ST concept appeared to represent an enormous advance in tokamak design. In 1985 ORNL proposed the Spherical Torus Experiment (STX). However, this was during a period when US fusion research budgets were being dramatically scaled back. ORNL was provided with funds to develop and test a prototype central solenoid column built with 6 layers of turns of a high-strength copper alloy called "Glidcop" (each layer with water cooling).

The inductance of a coil depends on its size, the number of turns, and the permeability of the material within and surrounding the coil. Formulas can be used to calculate the inductance of many common arrangements of conductors, such as parallel wires, or a solenoid. A small air-core coil used for broadcast AM radio tuning might have an inductance of a few tens of microhenries. A large motor winding with many turns around an iron core may have an inductance of scores or hundreds of henries.

Hansen Writing Ball was the first typewriter manufactured commercially (1870) In 1865, Rev. Rasmus Malling-Hansen of Denmark invented the Hansen Writing Ball, which went into commercial production in 1870 and was the first commercially sold typewriter. It was a success in Europe and was reported as being used in offices in London as late as 1909. Malling-Hansen used a solenoid escapement to return the carriage on some of his models which makes him a candidate for the title of inventor of the first "electric" typewriter.

A single stage coilgun For ferromagnetic projectiles, a single-stage coilgun can be formed by a coil of wire, an electromagnet, with a ferromagnetic projectile placed at one of its ends. This type of coilgun is formed like the solenoid used in an electromechanical relay, i.e. a current-carrying coil which will draw a ferromagnetic object through its center. A large current is pulsed through the coil of wire and a strong magnetic field forms, pulling the projectile to the center of the coil.

If it is, then the control unit activates a solenoid valve that directs boost pressure to the turbocharger's pneumatically controlled wastegate, that opens to bypass exhaust gases from the turbocharger directly to the exhaust pipe, lowering turbo boost pressure until the knock subsides. Knock events that are managed by the APC can be "seen" when the in-dash boost needle "twitches" slightly. The APC unit has a 'knock' output where an LED may be connected. This LED will then light up if knock is detected.

In 1981, a functional cowl-induction hood scoop was added. Under hard acceleration, a solenoid operated switch opened a flap that let in extra air. While produced without the front bench seat seen in the launch of the Citation, the interior of the X-11 was most widely differentiated with the use of a sport steering wheel. The X-11 was produced with its own instrument panel, which featured a full set of engine gauges (6000 RPM tachometer for 1980, 7000 RPM tachometer for 1981–1985).

The rocket engine nozzles were slightly offset to rotate the missile - this increased accuracy by evening out the effect of any slight asymmetry in thrust. This configuration drastically limited both range and flight duration, but was used because of fears that ionised particles in the hot, rocket motor exhaust stream would interfere with the guidance radar signals; further development showed the fears were unfounded. Steering was accomplished by four rudders in a cruciform configuration. These were moved by four pairs of pneumatic servos, operated by solenoid valves.

Alpha solenoid proteins are composed of repeating structural units containing at least two alpha helices arranged in an antiparallel orientation. Often the repeating unit is a helix-turn-helix motif, but it can be more elaborate, as in variants with an additional helix in the turn segment. Alpha solenoids can be formed by several different types of helical tandem repeats, including HEAT repeats, Armadillo repeats, tetratricopeptide (TPR) repeats, leucine-rich repeats, and ankyrin repeats. Alpha solenoids have unusual elasticity and flexibility relative to globular proteins.

Fractured bronze ring inside of a failed solenoid valve from Andrew J. Barberi. The initial discovery of the problem with the vessel's propulsion system occurred when the Barberi's chief engineer went up to the pilothouse after the collision. The engineer found that even though the pitch levers were in the neutral position, the propeller pitch indicator for the New York-end unit read out 50% thrust. This indication was confirmed by the stream of water that was being pushed away from the stern of the vessel.

The Maxwell-Lodge effect is a phenomenon of elctromagnetic induction in which an electric charge, near a solenoid in which current changes slowly, feels an electromotive force (e.m.f.) even if the magnetic field is practically static inside and null outside. It can be considered a classical analogue of the quantum mechanical Aharonov–Bohm effect, where instead the field is exactly static inside and null outside. The term appeared in the scientific literature in a 2008 article, referring to an article of 1889 by physicist Oliver Lodge.

Global Science Opera's second production, Ghost Particles, was performed globally on November 19, 2016 by 20 participating countries and streamed online by TV Haugaland. The chosen scientific theme was 'particle physics', with the opera exploring the science and discoveries of Higgs Boson, Neutrinos and Photons. The opera incorporated a virtual visit to CERN Compact Muon Solenoid. The 2016 GSO also involved the cooperation of the European Commissions' Horizons 2020 Project CREATIONS cooperated and was a research focus for the Norwegian Research Council's project "iSCOPE".

In this system, two bells placed either side of the operator are rung with a hammer made to strike the bell by a solenoid driven by a relay. They are so arranged that the right and left bells are struck according to whether a positive or negative pulse of current is received on the telegraph line. Such bells make a much louder sound than the clicking of a needle. The Magnetic found a method of overcoming the problem of dispersion on long submarine telegraph cables.

Pneumatic valves are operated by a pilot medium under pressure, usually compressed air but also oil or water. The valve is equipped with a pneumatic actuator supplied by a three-way solenoid valve. The pressure of the pilot medium enters the actuator cylinder and acts on the piston, which allows the seal to open or to close through the stem. The return of the seal into its rest position is usually achieved by a return spring that can be found in the pneumatic actuator.

In many older designs, kick-down is accomplished by mechanically actuating a valve inside the transmission. Most modern designs use a solenoid-operated valve that is triggered by a switch on the throttle linkage or by the engine control unit (ECU) in response to an abrupt increase in engine power. Mode selection allows the driver to choose between preset shifting programs. For example, Economy mode saves fuel by upshifting at lower engine speeds, while Sport mode (aka "Power" or "Performance") delays upshifting for maximum acceleration.

It also shows there is no linear relationship between the length of the linker DNA and the dimensions (instead there are two distinct classes). There is also data from experiments which cross-linked nucleosomes that shows a two-start structure. There is evidence that suggests both the solenoid and zig-zag (two-start) structures are present in 30 nm fibres. It is possible that chromatin structure may not be as ordered as previously thought, or that the 30 nm fibre may not even be present in situ.

The delay permits brief current surges beyond normal running current for motor starting, energizing equipment, etc. Short-circuit currents provide sufficient solenoid force to release the latch regardless of core position thus bypassing the delay feature. Ambient temperature affects the time delay but does not affect the current rating of a magnetic breaker.Hwaiyu Geng, Data Center Handbook, John Wiley & Sons,2014 page 542 Large power circuit breakers, applied in circuits of more than 1000 volts, may incorporate hydraulic elements in the contact operating mechanism.

The cylinder lock usually has several positions: locked, unlocked, online (will open if an impulse is given), and release. The release position is an intermittent position with a spring to push the cylinder back to the unlocked position. In the "locked" position, the drawer will remain latched even when an electric impulse is sent to the solenoid. Due to the increasing number of notes and varieties of notes, many cash drawers are designed to store notes upright & facing forward, instead of the traditional flat & facing upright position.

Unit cell of the A3B phases of Nb3Sn Mechanically, Nb3Sn is extremely brittle and thus cannot be easily drawn into a wire, which is necessary for winding superconducting magnets. To overcome this, wire manufacturers typically draw down composite wires containing ductile precursors. The "internal tin" process includes separate alloys of Nb, Cu and Sn. The "bronze" process contains Nb in a copper–tin bronze matrix. With both processes the strand is typically drawn to final size and coiled into a solenoid or cable before heat treatment.

Gabrielse was also one of the discoverers of the Brown-Gabrielse invariance theorem, relating the free space cyclotron frequency to the measureable eigenfrequencies of an imperfect Penning trap. The theorem's applications include precise measurements of magnetic moments and precise mass spectrometry. It also makes sideband mass spectrometry possible, a standard tool of nuclear physics. Gabrielse has also invented a self-shielding superconducting solenoid that uses flux conservation and a carefully chosen geometry of coupled coils to cancel strong field fluctuations due to external sources.

The main differences between the N55 and its N54 predecessor are the use of a single turbocharger, the addition of Valvetronic and the type of fuel injectors. Whilst the N54 used a twin-turbo arrangement, the newer N55 uses only a single twin scroll turbocharger. Valvetronic (variable valve lift) is claimed to improve throttle response, low-rev torque, exhaust emissions and to reduce fuel consumption by 15%. The direct injection system uses solenoid-type injectors, instead of the piezo-type fuel injectors used by its N54 predecessor.

Thrusters can provide large moments by imparting a couple on the spacecraft but inefficiencies in small propulsion systems cause thrusters to run out of fuel rapidly. Commonly found on nearly all CubeSats are magnetorquers which run electricity through a solenoid to take advantage of Earth's magnetic field to produce a turning moment. Attitude-control modules and solar panels typically feature built-in magnetorquers. For CubeSats that only need to detumble, no attitude determination method beyond an angular rate sensor or electronic gyroscope is necessary.

RH side VCT Oil Control Solenoid and harness from a Ford 4.6L SOHC 3V V8 engine Variable Camshaft Timing (VCT) is an automobile variable valve timing technology developed by Ford. It allows for more optimum engine performance, reduced emissions, and increased fuel efficiency compared to engines with fixed camshafts. It uses electronically controlled hydraulic valves that direct high pressure engine oil into the camshaft phaser cavity. These oil control solenoids are bolted into the cylinder heads towards the front of the engine near the camshaft phasers.

The BES III detector is a cylindrically symmetric 6-meter long and 7-meter diameter detector surrounding the interaction point of 2 beam pipe rings. It has 4 major detector layers: a main drift chamber (MDC), time- of-flight counter (TOF), cesium-iodide electromagnetic calorimeter (CsI EMC), and a muon counter (Muon Chamber, MC, µC). The inner three layers are inside of a 1 Tesla superconducting solenoid magnet. The main drift chamber (MDC) is the first inner detector layer around the beam pipe and collision point.

The Trilogy Select Fire, uses the 4-way valve integrated into the body of the gun rather than an electronic solenoid like other electronic frames. Though most markers in the Trilogy line are mechanical, it is possible to add an electronic trigger frame, which bypasses elements like the integrated 3-way. Later released Eclipse Blade 2 kits had an adapter for this purpose. The Trilogy can also be converted to manual pump-action, similar to the original Sniper line, which makes the integrated 4-way irrelevant.

Attached to the bottom of the handle is a rod that when pushed down contacts a solenoid or switch inside the control housing. The handle springs up if pressure is removed, releasing the rod's contact with the internal switch, instantly cutting power and applying the brakes. Though there are ways that this type of dead-man's control could conceivably fail, they have proven highly reliable. On some earlier equipment, pressure was not maintained on the entire controller, but on a large button protruding from the controller handle.

Berkelman (2004) p. 56 The CLEO collaboration was worried that the ARGUS detector at DESY would be better than CLEO, therefore it began to plan for an upgrade. The improved detector would use a new drift chamber for tracking and dE/dx measurements, a cesium iodide calorimeter inside a new solenoid magnet, time of flight counters, and new muon detectors. The new drift chamber (DR2) had the same outer radius as the original drift chamber to allow it to be installed before the other components were ready.

Repurposed elements from the Tevatron collider will be used to generate and deliver an 8 GeV proton beam. The protons would be extracted from Fermilab's Delivery Ring through a non-linear third-integer resonance extraction process and sent in pulses to the tungsten target. These protons will then collide with the tungsten production target in the production solenoid, producing a cascade of particles including pions, which decay into muons. Mu2e will produce between 200 and 500 quadrillion (2×1017 to 5×1017) muons per year.

A simple experiment can be conducted with fairly affordable equipment, and may be found in university-level undergraduate advanced physics laboratory courses. A metal such as 99.999% pure indium is commonly used: it is cooled using liquid helium to reach the conditions of low temperature, while the high magnetic field is accomplished using a superconducting solenoid. Ultimately, the experiment characterizes the resonance frequency and resonance width of the helicon standing waves. It can also be used to measure the magnetoresistance and Hall coefficients of the pure metal.

He earned his Ph.D at Joint Institute for Nuclear Research, Dubna, Russia in 1974. After working in Dubna for some years he emigrated in 1991 to the US to work on the Superconducting Super Collider project (SSC) in Dallas, Texas. When the project was cancelled in 1993 he transferred to work on the Compact Muon Solenoid project (CMS), working at the Fermi National Accelerator Laboratory in Chicago from 1994-1998. In 1995 he was also appointed Professor of Physics at UFL, rising to Distinguished Professor in 2004.

If the bit was beside an unmagnetized bar magnet in the card, the field was not opposed and the flip caused a current pulse in the twistor wire, reading a "1". However, by magnetizing the bar at that bit, the bar magnet opposed the field being created by the solenoid current, causing it to be below the write strength, and preventing the flip. This read a "0". The permanent magnet twistor (PMT) was re-programmed by removing the plates and placing them over a custom writer.

Spoofing locking hardware is fairly simple and more elegant than levering. A strong magnet can operate the solenoid controlling bolts in electric locking hardware. Motor locks, more prevalent in Europe than in the US, are also susceptible to this attack using a doughnut-shaped magnet. It is also possible to manipulate the power to the lock either by removing or adding current, although most Access Control systems incorporate battery back-up systems and the locks are almost always located on the secure side of the door.

A system is said to be in a two staged set up if two separate gas compressors in serial display work together to produce the compression. A normal booster installation is a two staged system that receives fluid that cools down the discharge of the first compressor, before arriving to the second compressor's input. The fluid that arrives to the interstage of both compressors comes from the liquid line and is normally controlled by expansion, pressure and solenoid valves. subcooled booster has a subcooling heat exchanger (SHX) that provides subcooling for the condensed liquid line.

Early pinball machines typically had full solenoid current passing through trigger switches for all types of solenoids, from kickers to pop bumpers to the flippers themselves. This caused arcing across switch contacts and rapid contact fouling and failure. As electronics were gradually implemented in pinball design, solenoids began to be switched by power transistors under software control to lower switch voltage and current, vastly extend switch service lifetime, and add flexibility to game design. As an example, some later machines had flippers that could be operated independently of the flipper button by the machine's software.

HPA tanks are more expensive because they must accommodate very high pressures. They are manufactured as steel, aluminium or wrapped carbon fiber tanks, the latter being the most expensive and most lightweight. Most players with electronic markers use HPA because if CO2 is used, the marker's electronic Solenoid valve can be damaged if liquid CO2 enters it. Users are warned not put any type of lubricant in the 'fill nipple' port of a HPA tank, as petroleum may burn when subjected to highly compressed air, causing an explosion, like in a diesel engine.

František Křižík Křižík's cores are magnetic solenoids cores shaped so as to insure an approximately uniform pull in different positions in the solenoid. His first experiments in Plzeň (Pilsen) resulted in the invention in 1880 of the automatic electric arc lamp, the so- called "Plzen Lamp" which was displayed at the International Exposition of Electricity in Paris in 1881. This lamp, with self-adjusting brushes, won the gold medal from among 50 similar devices. Later he successfully defended his patent against Werner Siemens claim to have created it first.

For variable valve timing, competing technologies (e.g., Honda's VTEC and BMW's VANOS) use electromechanical concepts, achieving valve lift variation via dedicated mechanisms, usually combined with camshaft phasers to allow control of both valve lift and phase. In contrast, Multiair uses managed hydraulic fluid to provide variable valve control. Control of a MultiAir engine's intake valves works via a valve tappet (cam follower), moved by a mechanical intake cam, which is connected to the intake valve through a hydraulic chamber, controlled by a normally open on/off solenoid valve.

This type of domain is extremely common among extracellular segments of receptors or cell adhesion molecules. A non-exhaustive list of examples include: EGF repeats, cadherin repeats, leucine-rich repeats, HEAT repeats, ankyrin repeats, armadillo repeats, tetratricopeptide repeats, etc. Whenever a linear solenoid domain structure participates in protein-protein interactions, frequently at least 3 or more repetitive subunits form the ligand-binding sites. Thus - while individual repeats might have a (limited) ability to fold on their own – they usually cannot perform the functions of the entire domain alone.

The objective of The Champion Pub is to train and later to fight in the pub by making the right shots with the ball. Toys on the playfield include for example a punching bag, a boxer figure and a jump rope that consists of a rotating wire that the ball has to jump over by using a button-controlled solenoid. A mini-playfield contains plastic fists instead of flippers. Game features include 4 Multi-ball modes and 15 Jackpot levels, 10 different international opponents and over 300 speech sound effects.

Pneumatic rack and pinion actuators A rack and pinion with two racks and one pinion is used in actuators. An example is pneumatic rack and pinion actuators that can be used to control valves in pipeline transport. The actuators in the picture on the right are used to control the valves of large water pipeline. In the top actuator, a gray control signal line can be seen connecting to a solenoid valve (the small black box attached to the back of the top actuator), which is used as the pilot for the actuator.

Though done to protect the print mechanism from damage, an unexpected keyboard lock activation could cause minor injury to a typist with a heavy touch. There was little obvious warning that the keyboard had locked or unlocked, other than a faint click from the interlock solenoid, easily drowned out by the printer and fan noise in many computer facilities. There was a small indicator light, but this was of little help to fast touch typists whose gaze was fixed on copy they were transcribing. The 2741 Selectric also had a special "print inhibit" feature.

Thirdly, ex situ methods would require the machine to be assembled both cold and pre-magnetized and would offer significant design difficulties. Until room temperature superconductors can be prepared, the most efficient design of machine will therefore be one in which an in situ magnetizing fixture is included! The first three methods all require a solenoid which can be switched on and off. In the first method an applied magnetic field is required equal to the required magnetic field, whilst the second and third approaches require fields at least two times greater.

It was small enough to fit inside a shoe. The data was input by tapping the big toe on a micro-switch in the shoe. Then an electronic signal was relayed to a vibrotactile output system hidden behind the shirt, strapped to the chest, which had three solenoid actuators near the stomach which would indicate by vibrating either which of the eight octants of the roulette wheel to place a bet on, or a ninth possibility: not to place a bet. It took two years to develop the computerized system.
|
|
However, there were problems: in one case the insulation failed and the bettor received electric shocks from the solenoids. But she kept placing bets, so the observer, who in this case was Farmer, left the table, so that the bettor would be forced to leave as well. Afterwards it turned out that the solenoid had burned a hole into her skin. Some members of the group had already left because of trouble juggling the academic schedule with the Eudaemons, but the burning incident caused the two leaders to disband the group.

Some industrial pattern types also include studded, metal rings to which the chains attach and thus are called ring chains. Most tire chains are wrapped around the circumference of the tires and held in place with rim chains, which may be chain or cable, elastic or adjustable tensioners. Automatic chains do not wrap around the tire but swing under the tire from devices permanently mounted under the vehicle which deploy via an electronic solenoid activated in the cab. Some tire chains mount onto the tires from only one side.

The plasma naturally wants to expand outwards to the walls of the tube, as well as move along it, towards the ends. The solenoid creates a magnetic field running down the centre of the tube, which the particles will orbit, preventing their motion towards the sides. Unfortunately, this arrangement does not confine the plasma along the length of the tube, and the plasma is free to flow out the ends. The obvious solution to this problem is to bend the tube around into a torus (a ring or doughnut shape).
|
|
Motion towards the sides remains constrained as before, and while the particles remain free to move along the lines, in this case, they will simply circulate around the long axis of the tube. But, as Fermi pointed out, when the solenoid is bent into a ring, the electrical windings would be closer together on the inside than the outside. This would lead to an uneven field across the tube, and the fuel will slowly drift out of the centre. Some additional force needs to counteract this drift, providing long-term confinement.

FROG has been firstly written by Loïc Quertenmont and Vincent Roberfroid in order to view, in a matter of seconds, events in the Compact Muon Solenoid detector. This detector is located at CERN and is dedicated to measure emitted particles produced by the collisions of high energetic protons accelerated by the Large Hadron Collider. Two other tools already exists in order to view events in the CMS detector : IGUANA and Fireworks. However, FROG has the advantage to have been implemented as such that any particular physics experiments or detector designs can be visualized.

The entire protein domain is composed of HEAT repeat domains, similar to those found in other proteins. Twelve of the fourteen helices (αA-αN) pair in an antiparallel pattern, and form six tandemly repeated α-α motifs, such as αA/αC, αD/αE, αF/αG, αH/αI, αJ/αK, and αL/αM. These helical repeats are stacked into a superhelical solenoid in which helices B, C, E, G, I, K and M form a concave surface with an aromatic cleft at its center. Residues within this cleft are crucial for the base excision activity.

The improvement saves fuel and by default goes into a wheel locked position. Should a failure occur in the vacuum solenoid, system, or hoses the wheel hub default to a 4wd position to keep from leaving a driver stranded. Internally, a 3-valve version of the 5.4 Liter V8 was introduced and replaced the previous 2-valve version. Externally, the eleventh-generation model was different from its predecessor, with sharper-edged styling; a major change was the adoption of the stepped driver's window from the Super Duty trucks.

Earlier systems used a mechanically rotated antenna (or solenoid) and an operator listening for peaks or nulls in the signal, which took considerable time to determine, often on the order of a minute or more. HF/DF's display made the same measurement essentially instantaneously, which allowed it to catch fleeting signals, such as those from the U-boat fleet. The system was initially developed by Robert Watson-Watt starting in 1926, as a system for locating lightning. Its role in intelligence was not developed until the late 1930s.

A number of inexpensive safes sold to households for under $100 use mechanical locking mechanisms that are vulnerable to bouncing. Many cheap safes use a magnetic locking pin to prevent lateral movement of an internal locking bolt, and use a solenoid to move the pin when the correct code is entered. This pin can also be moved by the impact of the safe being dropped or struck while on its side, which allows the safe to be opened. One security researcher taught his three- year-old son how to open most consumer gun safes.

Design of the unit injector eliminates the need for high-pressure fuel pipes, and with that their associated failures, as well as allowing for much higher injection pressure to occur. The unit injector system allows accurate injection timing, and amount control as in the common rail system . The unit injector is fitted into the engine cylinder head, where the fuel is supplied via integral ducts machined directly into the cylinder head. Each injector has its own pumping element, and in the case of electronic control, a fuel solenoid valve as well.

A leucine-rich repeat (LRR) is a protein structural motif that forms an α/β horseshoe fold. It is composed of repeating 20–30 amino acid stretches that are unusually rich in the hydrophobic amino acid leucine. These tandem repeats commonly fold together to form a solenoid protein domain, termed leucine-rich repeat domain. Typically, each repeat unit has beta strand-turn-alpha helix structure, and the assembled domain, composed of many such repeats, has a horseshoe shape with an interior parallel beta sheet and an exterior array of helices.

The cabin pressure is provided by the conditioned air entering the cabin through the distribution ducts and controlled by modulating the amount of air exhausted from the cabin. During ground operations, a solenoid limits the pressure differential to 0.25 psi in order to ensure normal functioning of the door and emergency exit. The pressure differential at final cruising altitude will be maintained at 8.7 psi difference between pressure altitude and cabin altitude. A rate controller enables the crew to select the rate pressurization of the cabin within preset limits.

Contemporary classical composer Hanspeter Kyburz's 1995 chamber work The Voynich Cipher Manuscript, for chorus & ensemble is inspired by the manuscript. In 2015, the New Haven Symphony Orchestra commissioned Hannah Lash to compose a symphony inspired by the manuscript. The novel Solenoid (2015), by Romanian writer Mircea Cartarescu uses the manuscript as literary device in one of its important themes. In the third season episode of the CBS crime drama Elementary titled "Under My Skin", the character of Sherlock Holmes studies the Voynich manuscript, stating that he disbelieves theories that the manuscript is extraterrestrial in origin.

In general, a toroidal inductor/transformer is more compact than other shaped cores because they are made of fewer materials and include a centering washer, nuts, and bolts resulting in up to a 50% lighter weight design. This is especially the case for power devices. Because the toroid is a closed-loop core it will have a higher magnetic field and thus higher inductance and Q factor than an inductor of the same mass with a straight core (solenoid coils). This is because most of the magnetic field is contained within the core.

As the system was not built in, there is a risk of damaging the pipe which is often under the car, releasing the pressurized fuel. The risk of this is minimized by locating the line in a protected position during installation. Modern installations also have a shutoff solenoid at the tank so that rupture will only release the fuel in the line rather than allowing fuel to come out of the tank. Car manufacturers are using ultra-high-strength steel (UHSS) to achieve the 5-star Government Crash Rating.

When driving straight ahead, a solenoid valve was operated by the control unit for the Hydractive suspension, which connected an additional spring ball in the hydraulic control circuit of the cylinder. Thereby, the stiffness of the tightly tuned stabilizer bars could be minimized "virtually" by gas filling the spring ball to reduce the movements and increase the comfort. Likewise, they had a damping effect on the control circuit, so that there were no undesired oscillations during straight-ahead driving due to suspension-related, short-term operation of the inclination corrector.

The SP-8 is an electro-pneumatic paintball marker manufactured by Smart Parts. It is the company's first attempt at a milsim marker, which are popular among scenario paintball players. Mechanically, the SP-8 is very similar to the popular Smart Parts Ion, but the body is modeled after the Heckler & Koch XM8 Assault Rifle. Features on the SP-8 include break beam eyes, high capacity solenoid, electronic double-finger trigger, and military style accessory rails, which can be used to mount sights, tactical lights, bipods, and other accessories.

The battery or capacitor powers a white LED lamp. The linear generator consists of a sliding rare earth magnet which moves back and forth through the center of a solenoid (a coil of copper wire) when it is shaken. A current is induced in the loops of wire by Faraday's law of induction each time the magnet slides through, which charges the capacitor through a rectifier and other circuitry. The best designs use a supercapacitor instead of a rechargeable battery, since these have a longer working life than a battery.

The histone H4 tail is essential for formation of 30 nm fibres. However, acetylation of core histone tails affects the folding of chromatin by destabilising interactions between the DNA and the nucleosomes, making histone modulation a key factor in solenoid structure. Acetylation of H4K16 (the lysine which is the 16th amino acid from the N-terminal of histone H4) inhibits 30 nm fibre formation. To decompact the 30 nm fibre, for instance to transcriptionally activate it, both H4K16 acetylation and removal of the histone H1 proteins are required.

On 9 November 2018, a Lilydale-bound service, led by 959M, uncoupled in running shortly after departing Croydon Station, splitting into two 3-car units, with the trailing unit coming to a stop under emergency braking. The subsequent investigation found that a wiring error during a modification to the train's low-note whistle on 959M, combined with a deterioration of insulation resistance in the uncouple solenoid connector of 882M (the leading car of the trailing unit), resulted in an error circuit forming which resulted in the unintended coupling.

As a sophomore at MIT, Pasterski was part of the CMS (Compact Muon Solenoid) experiment at the Large Hadron Collider.30 Under 30: Lindau Nobel Laureate Meeting, Scientific American profile She received academic freedom from her Harvard PhD advisor in the Spring of 2015 based upon Pasterski et al.'s 2014 discovery of the "spin memory effect" which may be used to detect or verify the net effects of gravitational waves. She would then complete the Pasterski–Strominger–Zhiboedov Triangle for electromagnetic memory in a 2015 solo paper that Stephen Hawking cited in early 2016.

A HEAT repeat is a protein tandem repeat structural motif composed of two alpha helices linked by a short loop. HEAT repeats can form alpha solenoids, a type of solenoid protein domain found in a number of cytoplasmic proteins. The name "HEAT" is an acronym for four proteins in which this repeat structure is found: _H_ untingtin, elongation factor 3 ( _E_ F3), protein phosphatase 2A (PP2 _A_ ), and the yeast kinase _T_ OR1. HEAT repeats form extended superhelical structures which are often involved in intracellular transport; they are structurally related to armadillo repeats.

The ZEUS detector comprised many components, including a depleted uranium plastic-scintillator calorimeter, a central tracking detector (which is a wire chamber), a silicon microvertex detector and muon chambers. In addition, a solenoid provides a magnetic field. The ZEUS experiment studied the internal structure of the proton through measurements of deep inelastic scattering by colliding leptons (electrons or positrons) with proton in the interaction point of ZEUS. These measurements were also used to test and study the Standard Model of particle physics, as well as searching for particles beyond the Standard Model.

It slides in and out of its lockable box and is secured by a spring-loaded catch. When a transaction that involves cash is completed, the register sends an electrical impulse to a solenoid to release the catch and open the drawer. Cash drawers that are integral to a stand-alone register often have a manual release catch underneath to open the drawer in the event of a power failure. More advanced cash drawers have eliminated the manual release in favor of a cylinder lock, requiring a key to manually open the drawer.

These inner CLICdet layers are enclosed in a superconducting solenoid magnet with a field strength of 4 T. This magnetic field bends charged particles, allowing for momentum and charge measurements. The magnet is then surrounded by an iron yoke which would contain large area detectors for muon identification. The detector also has a luminosity calorimeter (LumiCal) to measure the products of Bhabha scattering events, a beam calorimeter to complete the ECAL coverage down to 10 mrads polar angle, and an intra-train feedback system to counteract luminosity loss due to relative beam-beam offsets.

A major area of research in the early years of fusion energy research was the magnetic mirror. Most early mirror devices attempted to confine plasma near the focus of a non- planar magnetic field generated in a solenoid with the field strength increased at either end of the tube. In order to escape the confinement area, nuclei had to enter a small annular area near each magnet. It was known that nuclei would escape through this area, but by adding and heating fuel continually it was felt this could be overcome.

By placing a baseball coil at either end of a large solenoid, the entire assembly could hold a much larger volume of plasma, and thus produce more energy. Plans began to build a large device of this "tandem mirror" design, which became the Mirror Fusion Test Facility (MFTF). Having never tried this layout before, a smaller machine, the Tandem Mirror Experiment (TMX) was built to test this layout. TMX demonstrated a new series of problems that suggested MFTF would not reach its performance goals, and during construction MFTF was modified to MFTF-B.

An 8-track cartridge provides four pairs of stereo tracks, whereas the later quadraphonic cartridges had two sets of four tracks. The ends of the tape were spliced with a thin strip of metal that would trigger a solenoid that would cause the playback heads to automatically jump to the next set of channels. Both types of players also provided a button for manually changing channels. Due to the design of the endless loop tape, which fed from the reel in only one direction, there was no rewind control.

The magnetic field due to natural magnetic dipoles (upper left), magnetic monopoles (upper right), an electric current in a circular loop (lower left) or in a solenoid (lower right). All generate the same field profile when the arrangement is infinitesimally small. A magnetic dipole is the limit of either a closed loop of electric current or a pair of poles as the size of the source is reduced to zero while keeping the magnetic moment constant. It is a magnetic analogue of the electric dipole, but the analogy is not perfect.

Each marionette had two electrified wires that conducted the signals into its head; this contained a solenoid which, when operated by the signals, caused the puppet's lower lip to open and close with each syllable.La Rivière 2009, p. 29. The heads of regular characters were entirely fibreglass; proto-heads were sculpted in clay or Plasticine and then encased in rubber (or silicone rubber) to create moulds, to which fibreglass resin was applied to create the finished shells. Guest characters were played by puppets called "revamps", whose faces were Plasticine sculpted on featureless fibreglass heads.

The AFP from midges is structurally similar to those from Tenebrio and Dendroides, but the disulfide-braced beta-solenoid is formed from from shorter 10 amino-acids repeats, and instead of threonine, the ice-binding surface consists of a single row of tyrosine residues. Springtails (Collembola) are not insects, but like insects, they are arthropods with six legs. A species found in Canada, which is often called a "snow flea", produces hyperactive AFPs. Although they are also repetitive and have a flat ice- binding surface, the similarity ends there.

As a final extension, since 0.999... = 1 (in the reals) and ...999 = −1 (in the 10-adics), then by "blind faith and unabashed juggling of symbols"DeSua p. 901 one may add the two equations and arrive at ...999.999... = 0. This equation does not make sense either as a 10-adic expansion or an ordinary decimal expansion, but it turns out to be meaningful and true in the doubly infinite decimal expansion of the 10-adic solenoid, with eventually repeating left ends to represent the real numbersDeSua pp.

A coil forming the shape of a straight tube (a helix) is called a solenoid. The direction of the magnetic field through a coil of wire can be found from a form of the right-hand rule. If the fingers of the right hand are curled around the coil in the direction of current flow (conventional current, flow of positive charge) through the windings, the thumb points in the direction of the field inside the coil. The side of the magnet that the field lines emerge from is defined to be the north pole.

Sir Tejinder Singh Virdee, (born 13 October 1952), is an experimental particle physicist and Professor of Physics at Imperial College London. He is best known for originating the concept of the Compact Muon Solenoid (CMS) with a few other colleagues and has been referred to as one of the 'founding fathers' of the project. CMS is a world-wide collaboration which started in 1991 and now has over 3500 participants from 45 countries. Virdee was elected Fellow of the Royal Society and of the Institute of Physics (IOP) in 2012.

The control system is based on the very simple, robust and reliable equipment originated by English Electric, as is fitted to over 1500 diesel-electric shunting locomotives in service in various countries. Engine shutdown occurs if water temperature becomes too high or coolant level is too low, oil pressure is too low or engine overspeeds. Traction motor overload is prevented by relays which open if maximum current is exceeded. Automatic wheelslip is controlled by a relay which de-energises the governor override solenoid, bringing the load regulator towards minimum field.

This rule is used in two different applications of Ampère's circuital law: # An electric current passes through a straight wire. When the thumb is pointed in the direction of conventional current (from positive to negative), the curled fingers will then point in the direction of the magnetic flux lines around the conductor. The direction of the magnetic field (counterclockwise instead of clockwise when viewing the tip of the thumb) is a result of this convention and not an underlying physical phenomenon. # An electric current passes through a solenoid, resulting in a magnetic field.

An air gun is used for marine reflection and refraction surveys. It consists of one or more pneumatic chambers that are pressurized with compressed air at pressures from 14 to 21 MPa (2000 to 3000 lbf/in2). Air guns are submerged below the water surface, and towed behind a ship. When an air gun is fired, a solenoid is triggered, which releases air into a fire chamber which in turn causes a piston to move, thereby allowing the air to escape the main chamber and producing a pulse of acoustic energy.

A wastegate regulates the exhaust gas flow that enters the exhaust-side driving turbine and therefore the air intake into the manifold and the degree of boosting. It can be controlled by a boost pressure assisted, generally vacuum hose attachment point diaphragm (for vacuum and positive pressure to return commonly oil contaminated waste to the emissions system) to force the spring- loaded diaphragm to stay closed until the overboost point is sensed by the ecu or a solenoid operated by the engine's electronic control unit or a boost controller.

One of the challenges in using automated liquid handlers, or liquid handling robots, is in verifying the proper function of the device. Liquid handling operations, performed by these automated systems, can fail due to clogged pipette tips, failed solenoid valves, damaged labware, operator error and many other reasons. A variety of methods exist for performing quality control of liquid dispensing on automated platforms including gravimetric, fluorescent and colorimetric measurements. In addition to manual quality control methods, technologies have been developed which allow for the automated monitoring of quality control of liquid handling robots.

He later moved to UCLA where he became a Distinguished Professor of Physics & Astronomy for his contributions to the growth of the UCLA Physics & Astronomy Department. Rather than working in a U.S. based particle accelerator, the Superconducting Supercollider, Cline chose to work on CERN’s Large Hadron Collider. While there, he and others founded the Compact Muon Solenoid (CMS) experiment, which is still active today in investigating the Standard Model and is one of the largest international scientific collaborations in history. Cline was also involved in the development of the ICARUS neutrino detector.

CLEO was a hermetic detector that in all of its versions consisted of a tracking system inside a solenoid magnet, a calorimeter, particle identification systems, and a muon detector.CLEO I NIMCLEO II NIM The detector underwent five major upgrades over the course of its thirty-year lifetime, both to upgrade the capabilities of the detector and to optimize it for the study of B mesons. The CLEO I detector began collecting data in October 1979,Berkelman (2004) p. 30 and CLEO-c finished collecting data on March 3, 2008.

CLEO-c was the final version of the detector, and it was optimized for taking data at the reduced beam energies needed for studies of the charm quark. It replaced the CLEO III silicon detector, which suffered from lower-than-expected efficiency, with a six layer, all stereo drift chamber (ZD). CLEO-c also operated with the solenoid magnet at a reduced magnetic field of 1 T to improve the detection of low momentum charged particles. The low particle multiplicities at these energies allowed efficient reconstruction of D mesons.

Several faculty members carry out their research at the California NanoSystems Institute at UC Santa Barbara, CNSI-UCSB or the Institute for Terahertz Science and Technology.Institute for Terahertz Research and Technology Four faculty members from the department lead a large UCSB research group working at the Large Hadron Collider using the Compact Muon Solenoid (CMS). UCSB Professor Joseph Incandela is the spokesperson for the CMS collaboration. On 4 July 2012, Incandela spoke on behalf of CMS, where the discovery of a previously unknown boson with mass 125.3 ± 0.6 GeV/c2 was announced.

CMS is designed as a general-purpose detector, capable of studying many aspects of proton collisions at 0.9–13 TeV, the center-of-mass energy of the LHC particle accelerator. The CMS detector is built around a huge solenoid magnet. This takes the form of a cylindrical coil of superconducting cable that generates a magnetic field of 4 tesla, about 100 000 times that of the Earth. The magnetic field is confined by a steel 'yoke' that forms the bulk of the detector's weight of 12 500 t.
|
|
As the name “Compact Muon Solenoid” suggests, detecting muons is one of CMS's most important tasks. Muons are charged particles that are just like electrons and positrons, but are 200 times more massive. We expect them to be produced in the decay of a number of potential new particles; for instance, one of the clearest "signatures" of the Higgs Boson is its decay into four muons. Because muons can penetrate several metres of iron without interacting, unlike most particles they are not stopped by any of CMS's calorimeters.

Depending on the length of the repetitive units, their protein structures can be subdivided into five classes: # crystalline aggregates formed by regions with 1 or 2 residue long repeats, archetypical low complexity regions # fibrous structures stabilized by inter-chain interactions with 3-7 residue repeats # elongated structures with repeats of 5–40 residues dominated by solenoid proteins # closed (not elongated) structures with repeats of 30-60 residues as toroid repeats # beads on a string structures with typical size of repeats over 50 residues, which are already large enough to fold independently into stable domains.

Researchers at CERN believe they have created color-glass condensates during collisions of protons with lead ions. In these sorts of collisions, the standard outcome is that new particles are created and fly off in different directions. However, the Compact Muon Solenoid (CMS) team at the LHC found that in a sample of 2 million lead-proton collisions, some pairs of particles flew away from each other with their respective directions correlated. This correlation of directions is the anomaly that might be caused by the existence of a color-glass condensate while the particles are colliding.

A rack can release a store via gravity or by ejection. Ejection utilizes an impulse cartridge,IMPULSE AND DELAY CARTRIDGES Airman – Aviation theories and other practices a pyrotechnic device which provides jettison capability by igniting and supplying an ejection force to safely propel a store away from the rack and aircraft. Some racks contain an auxiliary cartridge in the event that the primary cartridges fail to fire. The rack will also have accessories such as a Zero Retention Force Arming Unit, a solenoid to pull arming wires from fuzes, ports for data, video or electrical fuzing.

GM resisted V8 power but eventually gave in to pressure from customers. (The exception to the above was the TDH-3301, which was powered by the GMC DH-478 Toroflow four-stroke V6, and had a more conventional T-drive transmission.) Original transmission choices were a four-speed non-synchronized manual transmission with solenoid reverse and the Allison Automatic VH hydraulic transmission. The latter was essentially a one-speed automatic transmission which drove the wheels through a torque converter. At sufficient speed a clutch bypassed the torque converter and the engine drove the rear wheels directly.

Troops explored the capabilities of LaBolenge chronographs and solenoid chronographs (two different instruments that record time intervals) for accuracy and reliability. 105-mm shells that had fired prematurely in battle were determined by research at SWPG to have faulty rotating bands, thus saving the lives of American troops. B-25s were sent from the airport in Hope to the Gulf of Mexico to observe the testing of bombs for tumbling and proper ballistics after being fired. After World War II the city of Hope received the Southwestern Proving Ground Airport, which became Hope Municipal Airport in 1947.

Repeats that are at least 30 to 40 amino acids long, are far more likely to be folded as part of a domain. Such long repeats are frequently indicative of the presence of a solenoid domain in the protein. Examples of disordered repetitive sequences include the 7-mer peptide repeats found in the RPB1 subunit of RNA polymerase II, or the tandem beta-catenin or axin binding linear motifs in APC (adenomatous polyposis coli). Examples of short repeats exhibiting ordered structures include the three-residue collagen repeat or the five-residue pentapeptide repeat that forms a beta helix structure.

A dishwasher containing clean dishes An open dishwasher A dishwasher is a machine for cleaning dishware and cutlery automatically. Unlike manual dishwashing, which relies largely on physical scrubbing to remove soiling, the mechanical dishwasher cleans by spraying hot water, typically between , at the dishes, with lower temperatures used for delicate items. A mix of water and dishwasher detergent is pumped to one or more rotating spray arms, blasting the dishes with the cleaning mixture. Once the wash is finished, the water is drained, more hot water enters the tub by means of an electro-mechanical solenoid valve, and the rinse cycle begins.

Start sequence was initiated by supplying energy to two spark plugs in the gas generator and two in the augmented spark igniter for ignition of the propellants. Next, two solenoid valves were actuated; one for helium control, and one for ignition phase control. Helium was routed to hold the propellant bleed valves closed and to purge the thrust chamber LOX dome, the LOX pump intermediate seal, and the gas generator oxidizer passage. In addition, the main fuel and ASI oxidizer valves were opened, creating an ignition flame in the ASI chamber that passed through the center of the thrust chamber injector.

The first system to be put into wide use was developed in 1905 by the Great Western Railway and protected by UK patents 12661 and 25955. Its benefits over previous systems were that it could be used at high speed and that it sounded a confirmation in the cab when a signal was passed at clear. In the final version of the GWR system, the locomotives were fitted with a solenoid-operated valve into the vacuum train pipe, maintained in the closed position by a battery. At each distant signal, a long ramp was placed between the rails.

The basic card punch mechanism was manufactured by Bull, a French company which owned patents on 80 column punch card machines. The machine came in two versions, the P147 and the P67, the main difference being electromagnetic clutch or a solenoid operated mechanical "dog" clutch to initiate a punch cycle. Since many gears, electrical contact cams were affixed to the main shaft with taper pins, the P 67 with its severe stopping dog clutch would cause timing loss more frequently than the P 147. Most emergency maintenance time was spent replacing worn and damaged taper pins and retiming the machine.

The size of the magnets is in the order of millimeters as well as their spacing. ; Electromagnets The use of electromagnets in magnetic tweezers has the advantage that the field strength and direction can be changed just by adjusting the amplitude and the phase of the current for the magnets. For this reason, the magnets do not need to be moved which allows a faster control of the system and reduces mechanical noise. In order to increase the maximum field strength, a core of a soft paramagnetic material with high saturation and low remanence may be added to the solenoid.

The throttle bypass/throttle solenoid system is combined with ignition retardation and slight fuel enrichment (mainly to provide cooling), typically ignition occurs at 35-45° ATDC. This late ignition causes very little expansion of the gas in the cylinder; hence the pressure and temperature will still be very high when the exhaust valve opens. At the same time, the amount of torque delivered to the crankshaft will be very small (just enough to keep the engine running). The higher exhaust pressure and temperature combined with the increased mass flow is enough to keep the turbocharger spinning at high speed thus reducing lag.

|
This was immediately ruled out, due to its complication for the mass-produced car. Other changes, however, were retained. These included fingerless crankshaft bearing caps, new cast iron camshaft supports with no bushings, inlet and outlet valves of increased diameter with double-wound-springs, a new water pump, vibration dampener on the crankshaft pulley, contactless ignition system with a new alternator, new spark plugs, and an upgraded K-126GM carburettor. Some cars would feature the K-151 carburettor with a paper air filter (as opposed to the traditional oil bath filters), and an idle fuel cutoff solenoid with exhaust gas recirculation.

The LS1 Firebirds were also equipped with an aluminum driveshaft, replacing the previous steel version, while all Firebird trim levels gained four-wheel disc brakes with dual-piston front calipers and larger rotors at each wheel, complete with a solenoid-based Bosch anti-lock system. The Formula convertible was no longer offered. Beginning in 1998 for 1999 models, a standard 16.8-gallon non-metallic fuel tank increased the potential traveling range. GM's ASR traction control system was extended to the V6-powered Firebirds, and all LS1 (V8) and Y87 (V6) Firebirds also received a Zexel/Torsen II slip- reduction rear axle.

Charged particles (black) naturally orbit around the lines of a magnetic field (green lines). In the mirror, the strong field at the ends causes the particles to slow and then reverse their motion along the lines. In 1951, as part of the first wave of research into fusion energy, University of California Radiation Laboratory at Livermore ("Livermore") researcher Richard F. Post introduced the magnetic mirror concept. The mirror is a deceptively simple device, consisting largely of a cylindrical vacuum chamber that holds the fusion fuel and an electromagnet wound around it to form a modified solenoid.

Linear compressors work similarly to a solenoid: by using a spring-loaded piston with an electromagnet connected to AC through a diode. The spring-loaded piston is the only moving part, and it is placed in the center of the electromagnet. During the positive cycle of the AC, the diode allows energy to pass through the electromagnet, generating a magnetic field that moves the piston backwards, compressing the spring, and generating suction. During the negative cycle of the AC, the diode blocks current flow to the electromagnet, letting the spring uncompress, moving the piston forward, and compressing the refrigerant.

Active Fuel Management (formerly known as displacement on demand (DoD)) is a trademarked name for the automobile variable displacement technology from General Motors. It allows a V6 or V8 engine to "turn off" half of the cylinders under light-load conditions to improve fuel economy. Estimated performance on EPA tests show a 5.5–7.5% improvement in fuel economy.Active Fuel ManagementTM Technology: Hardware Development on a 2007 GM 3.9L V6 OHV SI Engine - Document Number: 2007-01-1292 Date Published: April 2007 GM's current Active Fuel Management technology uses a solenoid to deactivate the lifters on selected cylinders of a pushrod V-layout engine.

The DECwriter LA30 was a 30 character per second dot matrix printing terminal introduced in 1970 by Digital Equipment Corporation (DEC) of Maynard, Massachusetts It printed 80 columns of uppercase-only 7×5 dot matrix characters across a unique-sized paper. The printhead was driven by a stepper motor and the paper was advanced by a noisy solenoid ratchet drive. The LA30 was available with both a parallel interface (LA30-P) and a serial interface (LA30-S); however, the serial LA30 required the use of fill characters during the carriage-return. In 1972, a receive-only variation named LA30A became available.

Computer simulations indicated that a conventional spiral inductor of 205 microns in diameter could be matched by a nanocoil just 70 nanometers wide, with a field strength reaching as much as 1 tesla, about the same as the coils found in typical loudspeakers, about the same field strength as some MRI machines. They found the magnetic field would be strongest in the hollow, nanometer-wide cavity at the spiral's center. A solenoid made with such a coil behaves as a quantum conductor whose current distribution between the core and exterior varies with applied voltage, resulting in nonlinear inductance.

Sakharov suggested to replace the copper coil in his MK generators by a big superconductor solenoid to magnetically compress and focus underground nuclear explosions into a shaped charge effect. He theorized this could focus 1023 positively charged protons per second on a 1 mm2 surface, then envisaged making two such beams collide in the form of a supercollider. Underground nuclear explosive data from peaceful nuclear explosion test shots have been used to investigate the composition of Earth's mantle, analogous to the exploration geophysics practice of mineral prospecting with chemical explosives in "deep seismic sounding" reflection seismology.

There are a couple of solenoids at the paper tray input mechanism that have felt pads designed to cushion them when they snap on, and the glue holding these pads in place can migrate to the surface. This delays the release of the solenoid, which causes the paper to start feeding slightly late. The error accumulates with each page printed, and eventually the paper is entering the mechanism so late that the printer believes that a jam has occurred. The tell- tale symptom is a print job with a top margin that shrinks from page to page.

The resonant cavity is formed by the highly reflective nickel cathode and the semitransparent grid anode. Since the source is located at the end of the solenoid which generates the main LAPD background field, there is a gradient in the magnetic field within the cavity. As shear waves do not propagate above the ion cyclotron frequency, the practical effect of this is to act as a filter on the modes which may be excited. Maser activity occurs spontaneously at certain combinations of magnetic field strength and discharge current, and in practice may be activated (or avoided) by the machine user.

The second type of Z-axis control is through the use of a pneumatic cylinder and a software-driven gate valve. Due to the small cylinder size and the amount of air pressure used to drive it there is little range of control between the up and down stops. Both the solenoid and pneumatic system cannot position the head anywhere other than the endpoints, and are therefore useful for only simple 'up/down' milling tasks. The final type of Z-axis control uses a stepper motor that allows the milling head to be moved in small accurate steps up or down.

A switch in the gear lever operated a solenoid valve so that when the gear lever moved, the clutch was disengaged. A control unit made throttle adjustments to keep the engine speed matched to the driven clutch plate and also varied the speed of clutch operation appropriate to road speed.Staton Abbey (ed) Practical Automobile Engineering Clutch Systems p 193-194 ;Newtondrive The Newtondrive system differed in making a provision for choke control and a cable linkage from the clutch operating mechanism to the throttle. The systems could be fitted to smaller cars such as the Ford Anglia.

Drum brakes were released by an electric solenoid operating from low-voltage battery power; a power failure would prevent the drums from releasing which would prevent power application, a fail-safe feature. Drum brakes were quite popular and greatly reduced maintenance thus some "Air" cars were retrofitted with drums. Four magnetic brakes, one between the wheels on each side of each truck, applied additional braking for emergency stopping where all brakes were generally employed. "These performances [acceleration and braking] enable the P.C.C. car to out- pace the average automobile which, in America, is of substantially higher performance than the typical British vehicle."H.

The invention of programmable logic controllers (PLC) allowed gas meter repair facilities to automate most of the manual bell prover's process and calculations. Instead of manually raising and lowering the bell prover, solenoid valves connected to a PLC control air flows through the meter. Temperature, pressure, and humidity sensors can be used to feed data into an automated bell PLC, and calculations for meter proofs can be handled by a computer or electronic device programmed for such a purpose. In the early 1990s, the PLC was replaced by PACs (Programmable Automated Controls) and modern computer systems.

In electric cars such as the Nissan Leaf and Mitsubishi i-MiEV, B mode increases the level of regenerative braking when the accelerator pedal is released. Some automatic transmissions modified or designed specifically for drag racing may also incorporate a transbrake as part of a manual valve body. Activated by electrical solenoid control, a trans brake simultaneously engages the first and reverse gears, locking the transmission and preventing the input shaft from turning. This allows the driver of the car to raise the engine RPM against the resistance of the torque converter, then launch the car by simply releasing the trans brake switch.

1949 Oldsmobile Futuramic 98 1953 Oldsmobile 98 convertible Oldsmobile 98 Fiesta style "spinner" hubcap 1952 Oldsmobile 98 convertible For the first time since 1940 Oldsmobile offered totally different styling during a single model year. The top of the line 1948 Oldsmobile 98 drew heavily from the Futuramic styling concept that would be used on all 1949 Oldsmobiles. Standard equipment on 98s included a solenoid starter, fender skirts, E-Z-l rearview mirror, and foam rubber seat cushions. The 98s also included front and rear bumper guards, vacuum booster pump, plastic radiator ornament, dual horns, dual sun visors, and cigarette lighter.

Nissan Variable Timing control or Nissan Valve Timing Control System (commonly known as N-VTC, VTC, NVCS or NVTCS) is an automobile variable valve timing technology developed by Nissan. N-VTC was first introduced in 1987 on the VG30DE and VG20DET engine. N-VTC varies valve timing by rotating the affected camshaft(s) relative to the sprocket; valve lift and duration are not altered. This rotation is achieved when an electric solenoid, controlled by the car's ECU, allows pressurized engine oil to flow into and through the cam and into a slave mechanism, axially advancing camshaft timing relative to the sprocket.

Instead of magnetic rings, the cores, rod memory uses magnetic bars surrounded by a metal coil. Instead of the electrical current running linearly and the magnetic field around the core, in rod memory the current runs around the solenoid and the magnetic field is linear in the rod. The end result is essentially the same, however, with the bits being represented by the direction of the magnetic field in the rod. To do this, the rods are placed in the middle of tiny solenoids, which produce a linear field in one direction or the other depending on which direction the current is flowing.

The Riefler escapement, used in Clemens-Riefler regulator clocks was accurate to 10 milliseconds per day. Electromagnetic escapements, which used a switch or phototube to turn on a solenoid electromagnet to give the pendulum an impulse without requiring a mechanical linkage, were developed. The most accurate pendulum clock was the Shortt-Synchronome clock, a complicated electromechanical clock with two pendulums developed in 1923 by W.H. Shortt and Frank Hope-Jones, which was accurate to better than one second per year. A slave pendulum in a separate clock was linked by an electric circuit and electromagnets to a master pendulum in a vacuum tank.

Diesel fuel injector as installed in a MAN V8 Diesel engine Common rail direct fuel injection is a direct fuel injection system for diesel engines. It features a high-pressure (over ) fuel rail feeding solenoid valves, as opposed to a low-pressure fuel pump feeding unit injectors (or pump nozzles). Third- generation common rail diesels now feature piezoelectric injectors for increased precision, with fuel pressures up to . High pressure injection delivers power and fuel consumption benefits over earlier lower pressure fuel injection, by injecting fuel as a larger number of smaller droplets, giving a much higher ratio of surface area to volume.

On 16 April 2009 Haldex announced a deal worth SEK4.5B (approx US$530M) to provide Volkswagen with a new AWD system for the company's new modular platform due in 2012. The GenV AWD coupling, now distributed by BorgWarner TorqTransfer Systems, features a new design aimed at reducing vehicle complexity and simplifying integration into the drivetrain. A new electro-hydraulic clutch actuator uses a centrifugal overflow valve design aimed at accurately distributing power between the front and rear axles, and eliminating the need for an accumulator, solenoid valve and filter. It also employs an integrated electronic control unit.

In 1997 PAEC chairman Ishfaq Ahmad reached out to CERN to sign a contract between them after elaborate discussions an in-kind contribution worth one million Swiss francs for the construction of eight magnet supports for the Compact Muon Solenoid (CMS) detector. For the CMS, the PAEC built magnetic feet and installed 320 Resistive Plate Chambers (RPC), as well as contributing to CMS computing. Several other mechanical components for ATLAS and for the LHC were also built by the PAEC. It was PAEC's efforts that led the Institute of Nuclear Science and Technology (PINSTECH) with CERN's direct cooperation in the area of radioprotection.

The final complete system came in 1927 when Berlin-based Max Ruhl and Ernst Neuman combined internal illumination and solenoid operation. The shape of the trafficator arm is closely based upon the shape of the semaphore signal arm used by the Royal Bavarian Railway beginning in 1890. The only difference from the railway arm is that it is halved down its length so as to fit flush with the vehicle's exterior. They were common on vehicles until the introduction of the flashing amber, red or white indicators at or near the corners of the vehicle (and often along the sides as well).

This 12 Valve mode results in swirl of the intake charge which increases combustion efficiency, resulting in improved low end torque and better fuel economy. At 3000-5400 RPM, depending on load, one of the VTEC solenoids engages, which causes the second valve to lock onto the first valve's camshaft lobe. Also called 16-valve mode, this method resembles a normal engine operating mode and improves the mid-range power curve. At 5500-7000 RPM, the second VTEC solenoid engages (both solenoids now engaged) so that both intake valves are using a middle, third camshaft lobe.

After decades of planning and construction the Compact Muon Solenoid (CMS) is a next generation detector for the new proton-proton collider (7 TeV + 7 TeV) called the Large Hadron Collider (LHC) which is now operational in the existing 17 mi (27 km) circular tunnel near Geneva, Switzerland at CERN, the European Laboratory for Particle Physics. Florida State University faculty members collaborated in the design, construction and operation of the LHC, with some components assembled at Florida State and shipped to CERN for installation. Florida State faculty contributed to several areas of the CMS, especially the electromagnetic calorimeter and the hadron calorimeter.

Drukqs contains tracks dating back "seven or eight years", according to James, though most of the album was relatively new. The LP is a double album featuring roughly two styles: rapid, meticulously- programmed tracks utilizing exaggerated drum 'n' bass breakbeats, and classical piano pieces made using computer-controlled instruments such as a modified Yamaha Disklavier and several MIDI-controlled, solenoid-based drum mechanisms made by James. NME noted that the album moves through techno, drum 'n' bass, and early-90s rave, while the piano interludes were compared to the work of Erik Satie. Pitchfork also noted "several purely electro-acoustic excursions".

The stator blades moved from high to low position by an electrical solenoid and a stator valve, controlled by a switch on the throttle linkage. At light to medium throttle, the stator blades were at 32°, providing a torque multiplication of 1.8:1 and a converter stall speed of approximately 1800 rpm. At ⅔ to full throttle, the blades switched to the 51° high position, giving torque multiplication of 2.45:1 and a stall speed of approximately 2300 rpm. The blades were also set to the high position at idle to limit creep when stopped in Drive.

The C-series borrowed features from the American police motorcycles with which it was designed to compete. These included a spring-cushioned saddle, and a speedometer equipped with a solenoid to trap the indicator needle against the glass when the pursuit lights were activated, to mark the speed at which a lawbreaker was traveling at the time. Both of these features were eliminated in the KZP, which was equipped with a standard speedometer and tachometer. The engine was updated in 1981 from the Z1 type with a displacement of 1015 cc to the "J model" type with a displacement of 998 cc.

The Astron device consisted of two sections, the linear accelerator and the magnetic mirror "tank". These were constructed at right angles, with the accelerator's output firing into the side of the tank at one end. The tank was a relatively simple example of the magnetic mirror concept, consisting largely of a long solenoid with additional windings at both ends to increase the magnetic field in those regions and form the mirror. In a simple mirror the ions in the fuel plasma were injected at an angle so they could not simply flow right out of the ends where the field was roughly linear.

Hydraulic dashpots or hydraulic-action timers are similar in appearance and operation to pneumatic timers. Hydraulic-action timers work by energizing the solenoid coil which pulls the hollow core into the center of the coil. Fluid in the hollow core is then forced to go through an orifice at the top, a one way check valve at the bottom of the hollow core prevents the fluid from escaping through the bottom. After the fluid is expelled, the core completes its upward movement and closes an air gap in the core, which in turn increases its electromagnetic field strength.

This system utilizes the engine lube oil to control the closure of inlet valve. The intake valve opening mechanism incorporates a valve tappet and a piston inside a chamber. There is a solenoid valve controlled by the engine control system which gets energized and supplies oil through a non-return valve during the time of cam lift and the oil gets filled in the chamber and the return channel to the sump is blocked by the valve tappet. During the downward movement of the cam, at a particular instant, the return passage opens and the oil pressure gets released to the engine sump.

Both iron-core and superconducting electromagnets have limits to the field they can produce. Therefore, the most powerful man-made magnetic fields have been generated by air-core nonsuperconducting electromagnets of a design invented by Francis Bitter in 1933, called Bitter electromagnets. Instead of wire windings, a Bitter magnet consists of a solenoid made of a stack of conducting disks, arranged so that the current moves in a helical path through them, with a hole through the center where the maximum field is created. This design has the mechanical strength to withstand the extreme Lorentz forces of the field, which increase with B2.

There are eight theoretical classes of steric-zipper interfaces, dictated by the directionality of the β-sheets (parallel and anti-parallel) and symmetry between adjacent β-sheets. A limitation of X-ray crystallography for solving amyloid structure is represented by the need to form microcrystals, which can be achieved only with peptides shorter than those associated with disease. Although bona fide amyloid structures always are based on intermolecular β-sheets, different types of "higher order" tertiary folds have been observed or proposed. The β-sheets may form a β-sandwich, or a β-solenoid which may be either β-helix or β-roll.

If the back block is not kept rearward long enough for a paintball to drop fully into the chamber, a "dry fire" or a "ball chop" may occur, the latter being extremely frustrating as it drastically affects accuracy of future shots until the barrel, breech and bolt are cleaned. The need for a full trigger pull on mechanical Autocockers also results in a slower rate of fire. Sear Trip: Even with an electronic trigger, the Autococker still relies on a hammer and spring valve for firing. The electronic trigger controls the recocking pneumatics, and a sear solenoid.

The UK responsibility within the DELPHI project was in three technical areas: the outer detector, primarily Liverpool; the barrel muon chambers, primarily Oxford; and the data acquisition system, primarily RAL. However, the UK groups were centrally funded, and RAL with its relatively large engineering and design capabilities participated in all three activities when need arose. The Rutherford Appleton Laboratory also designed and constructed the large super conducting solenoid which surrounded the DELPHI detector. In 1998, Kalmus took sabbatical leave from the Rutherford Appleton Laboratory and joined the NA48 Experiment at CERN whose prime purpose was to measure "direct" CP violation in Kzero decays.

The driver typically applies full throttle at this time, and the car remains stationary at the starting line under full engine power. When the driver sees the desired visual cue before him, the driver promptly releases his finger (or thumb) from the pushbutton. This button release opens the contacts within the pushbutton switch signaling the delay box and the delay box now begins an internal countdown. When the countdown timer reaches zero, the delay box stops current flowing to the solenoid in the transmission and that causes the spool valve to return to its normal position.

However, this initial proposal ignored a fundamental problem; when arranged along a straight solenoid, the external magnets are evenly spaced, but when bent around into a torus, they are closer together on the inside of the ring than the outside. This leads to uneven forces that cause the particles to drift away from their magnetic lines. During visits to the Laboratory of Measuring Instruments of the USSR Academy of Sciences (LIPAN), the Soviet nuclear research centre, Sakharov suggested two possible solutions to this problem. One was to suspend a current-carrying ring in the centre of the torus.

These bikes had 1000 cc Mini engines with foot-operated automatic gear boxes (including reverse), side-mounted radiators, chain drive, Yamaha alloy wheels, Austel leading link forks and were named Lotec due to the simplicity of design. The natural design progression from the Lotec was the Pullman combination motorcycle. The heavy but economic Mini engine lent itself to having a sidecar attached for long- distance touring. The first Austel Pullman prototype appeared in 1987 with a Mini 850 cc engine, shaft drive, solenoid-operated handlebar-mounted gear change, drum brakes, Austel 8-spoke steel wheels and leading link anti dive front forks.

The CMS magnet is the central device around which the experiment is built, with a 4 Tesla magnetic field that is 100,000 times stronger than the Earth's. CMS has a large solenoid magnet. This allows the charge/mass ratio of particles to be determined from the curved track that they follow in the magnetic field. It is 13 m long and 6 m in diameter, and its refrigerated superconducting niobium-titanium coils were originally intended to produce a 4 T magnetic field. The operating field was scaled down to 3.8 T instead of the full design strength in order to maximize longevity.

92 An externally mounted M2 was later adopted for the commander's position on the M1 Abrams tanks. Three subvariants were also developed for use by the U.S. Navy on a variety of ships and watercraft including the soft mount and fixed type versions. The fixed types fire from a solenoid trigger and come in left or right hand feed variants for use on the Mk 56 Mod 0 dual mount and other mounts. Huaqing Machinery has made a clone of the M2HB known as the CS/LM6, which was released publicly in 2010 in foreign weapons expo conventions.

The term "voice coil" has been generalized and refers to any galvanometer-like mechanism that uses a solenoid to move an object back-and-forth within a magnetic field. In particular, it is commonly used to refer to the coil of wire that moves the read–write heads in a moving-head disk drive. In this application, a very lightweight coil of wires is mounted within a strong magnetic field produced by permanent rare-earth magnets. The voice coil is the motor part of the servo system that positions the heads: an electric control signal drives the voice coil and the resulting force quickly and accurately positions the heads.

If the gyro's spin axis is not vertical, the added weight in the lower tank would pull the housing over if it were not for the gyro and the housing's rotation. That rotational speed and rate of mercury flow combine to put the heavier tank in the best position to make the gyro precess toward the vertical. When the ship changes course rapidly at speed, the acceleration due to the turn can be enough to confuse the gyro and make it deviate from true vertical. In such cases, the ship's gyrocompass sends a disabling signal that closes a solenoid valve to block mercury flow between the tanks.

Capstans traditionally had unequal diameters and different flywheel masses. The speeds of the quartz- controlled capstans were spread apart to ensure the trailing (braking) capstan always lagged behind the leading capstan by 0.2%, in either forward or reverse mode, to properly tension the tape and isolate it from the cassette shell. The third motor spun both tape spools, the fourth motor drove the NAAC servo, and the fifth one smoothly raised and lowered the head assembly in place of the usual solenoid). Both pinch rollers were enclosed in wraparound tape-guide blocks; ordinary unidirectional decks with double-capstan transports had only one such block.

PLUTO was the first electromagnetic superconductive solenoid in the world, with a very uniform axial magnetic field of 12000 Gauss,Such magnets were later used for Nuclear Magnetic Resonance (NMR) spectroscopy for medical analysis to operate in a straight section of e+e− accelerators at DESY, first with DORIS I (a storage ring at center of mass energies of ~3-5 GeV) in 1974-1976, then with DORIS II (the upgraded storage ring of DORIS I at center of mass energies of ~7-10 Gev) in 1978 and later with PETRA (also a storage ring, at larger center of mass energies of ~10-45 GeV) in 1978-1982 (see review ).

START proved to exceed even the most optimistic predictions and MAST confirmed the results of its forerunner on a larger, more purpose-built experiment. It was fully commissioned by EURATOM/UKAEA and took two years to design and a further two years to construct. MAST included a neutral beam injector similar to that used on START for plasma heating, and used the same merging compression technique for plasma formation instead of the conventional direct induction. Merging compression provides a valuable saving of central solenoid flux, which can then be used to further ramp up the plasma current and/or maintain the required current flat-top.

The driver must bring the vehicle up to speed manually and use a button to set the cruise control to the current speed. The cruise control takes its speed signal from a rotating driveshaft, speedometer cable, wheel speed sensor from the engine's RPM, or from internal speed pulses produced electronically by the vehicle. Most systems do not allow the use of the cruise control below a certain speed - typically around . The vehicle will maintain the desired speed by pulling the throttle cable with a solenoid, a vacuum driven servomechanism, or by using the electronic systems built into the vehicle (fully electronic) if it uses a 'drive-by-wire' system.

Once the spin cycle is completed, centrifugal force no longer suspends the fabric softener and it falls through the center of the agitator to join the rinse water coming into the tub. The same objective must be accomplished by a solenoid valve or a pump, and associated timer controls and wiring, on a front loader. A lint trap can also be built into the center of the agitator, or on the drum's walls, passively collecting lint from water forced through the agitator. Front- loaders tend to require separate pumps and plumbing to provide lint filters which are often mounted behind covers on the bottom of the machine.

Each distant signal had its own battery, operating at 12.5 V or more; the resistance if the power came directly from the controlling signal box was thought too great (the locomotive equipment required 500 mA). Instead, a 3 V circuit from a switch in the signal box operated a relay in the battery box. When the signal was at 'danger', the ramp battery was disconnected and so could not replace the locomotive's battery current: the brake valve solenoid would then be released and a horn sounded in the cab. The driver was then expected to cancel the warning and apply the brakes under his own control.

Ideally, 100% of the magnetic flux generated by the coil would be delivered to and act on the projectile; in reality this is impossible due to energy losses always present in a real system, which cannot be entirely eliminated. With a simple air-cored solenoid, the majority of the magnetic flux is not coupled into the projectile because of the magnetic circuit's high reluctance. The uncoupled flux generates a magnetic field that stores energy in the surrounding air. The energy that is stored in this field does not simply disappear from the magnetic circuit once the capacitor finishes discharging, instead returning to the coilgun's electric circuit.

High-pressured industrial gas bottles (such as nitrogen or carbon dioxide tanks used to store shielding gases for welding) are sometimes used in more radical air suspension setups. Either of these reservoir systems may be fully adjustable, being able to adjust each wheel's air pressure individually. This allows the user to tilt the vehicle side-to-side, front-to-back, in some instances "hit a 3-wheel" (contort the vehicle so one wheel lifts up from the ground) or even "hop" the entire vehicle into the air. When a pressure reservoir is present, the flow of air or gas is commonly controlled with pneumatic solenoid valves.

Iran is an active member of COMSTECH and collaborates on its international projects. The coordinator general of COMSTECH, Dr. Atta ur Rahman has said that Iran is the leader in science and technology among Muslim countries and hoped for greater cooperation with Iran in different international technological and industrialization projects. Iranian scientists are also helping to construct the Compact Muon Solenoid, a detector for the Large Hadron Collider of the European Organization for Nuclear Research (CERN) that is due to come online in 2008. Iranian engineers are involved in the design and construction of the first regional particle accelerator of the Middle East in Jordan, called SESAME.

Cars with nitrous-equipped engines may be identified by the "purge" of the delivery system that most drivers perform prior to reaching the starting line. A separate electrically operated valve is used to release air and gaseous nitrous oxide trapped in the delivery system. This brings liquid nitrous oxide all the way up through the plumbing from the storage tank to the solenoid valve or valves that will release it into the engine's intake tract. When the purge system is activated, one or more plumes of nitrous oxide will be visible for a moment as the liquid flashes to vapor as it is released.

This may cause confusion when working with compound machines like brushless alternators, or in conversation among people who are accustomed to work with differently configured machinery. In most generators, the field magnet is rotating, and is part of the rotor, while the armature is stationary, and is part of the stator. Both motors and generators can be built either with a stationary armature and a rotating field or a rotating armature and a stationary field. The pole piece of a permanent magnet or electromagnet and the moving, iron part of a solenoid, especially if the latter acts as a switch or relay, may also be referred to as armatures.
|
|
In a stepper motor an internal rotor containing permanent magnets or a magnetically soft rotor with salient poles is controlled by a set of external magnets that are switched electronically. A stepper motor may also be thought of as a cross between a DC electric motor and a rotary solenoid. As each coil is energized in turn, the rotor aligns itself with the magnetic field produced by the energized field winding. Unlike a synchronous motor, in its application, the stepper motor may not rotate continuously; instead, it "steps"—starts and then quickly stops again—from one position to the next as field windings are energized and de-energized in sequence.

In the days before automatic transmissions were common, especially in the 1950s, many rear-wheel drive American cars were available with an overdrive option. With substantial improvements developed in Muncie, Indiana, by William B. Barnes for production by its Warner Gear Division, BorgWarner provided the box that was factory-installed between the transmission and a foreshortened driveshaft. Since the overdrive function, if enabled, could be shifted by simply easing up on the accelerator without depressing the clutch pedal, the action was much like a semi-automatic. Also, an electrically operated solenoid would deactivate the unit via a switch under the accelerator pedal providing the equivalent of the kickdown of the automatic.

Technically, CO2 and HPA can propel the paintball, but when high rates of fire are attained, liquid is sucked into the marker which can damage or even destroy electrical components inside the marker such as the solenoid. Never leave a CO2 container in sunlight, as the heat will cause the gas to expand to a dangerous level. The tanks include safety valves in their construction, but there is no need to use them or take unnecessary risks. With normal back- bottle setups (or, air systems utilizing a horizontal air source adapter, more commonly called an ASA), the less dense gaseous CO2 will rise to the top half of the tank.

Single-position lap bars on wooden roller coasters are sometimes referred to as "buzz bars," a slang term named for the buzzing sound that some bars make as they lock or release. The term can be misleading as the buzzing sound only occurs on Philadelphia Toboggan Company (PTC) trains when the solenoid that releases the bar is out of alignment. There are other train types, such as NAD and even some PTC trains, that feature a single-position lap bar that has a mechanical release and therefore does not produce a buzzing sound. Most parks have switched to individual ratcheting lap bars, similar to the lap bars found on steel coasters.

The structure of the clathrin heavy chain leg segment showing helical repeats, with the N-terminus in blue at left and the C-terminus in red at right. Vesicle coat proteins frequently contain alpha solenoids and share common domain architecture with some NPC proteins. Three major coat complexes involved in distinct cellular pathways all contain alpha solenoid proteins: the clathrin/adaptin complex, which buds vesicles from the plasma membrane and is involved in endocytosis; the COPI complex, which buds vesicles from the Golgi apparatus and is associated with retrograde transport; and the COPII complex, which buds vesicles from the endoplasmic reticulum and is associated with anterograde transport.

For this reason other microsystem fabrication technology such as bulk micromachining, LIGA and micro-injection molding should be applied. For solenoid coils adding more turns to the coil will enhance the B1/i ratio and thus both the inductance and the signal response. At the same time the coil resistance will increase linearly, so the improvement in sensitivity will be proportional to the square root of the number of turns (n). At the same time we will have a larger ohmic heating at the center of the coil and an enhanced danger for arcing, so the optimum is generally found for only a limited number of turns.

Some early RCDs were entirely electromechanical and relied on finely balanced sprung over-centre mechanisms driven directly from the current transformer. As these are hard to manufacture to the required accuracy and prone to drift in sensitivity both from pivot wear and lubricant dry-out, the electronically-amplified type with a more robust solenoid part as illustrated are now dominant. In the internal mechanism of an RCD, the incoming supply and the neutral conductors are connected to the terminals at (1), and the outgoing load conductors are connected to the terminals at (2). The earth conductor (not shown) is connected through from supply to load uninterrupted.

The FS uses a spool system similar to an Automag, but instead of incorporating a shut-off valve, and using a sear/spring arrangement to return the bolt from its blow-forward operation, it uses air pressure. The system has full-pressure supply air stored in a dump chamber in the rear of the marker. This pressure is applied to the center pin in the rear of the bolt, which is biased to push it open. The regulated air supplied by a front Low Pressure Regulator (LPR) is run through a 2/3-way solenoid valve that is designed to be "Normally On" when it is not energized.

DNA in the nucleus is wrapped around nucleosomes, which are histone octamers formed of core histone proteins; two histone H2A-H2B dimers, two histone H3 proteins, and two histone H4 proteins. The primary chromatin structure, the least packed form, is the 11 nm, or “beads on a string” form, where DNA is wrapped around nucleosomes at relatively regular intervals, as Roger Kornberg proposed. Histone H1 protein binds to the site where DNA enters and exits the nucleosome, wrapping 147 base pairs around the histone core and stabilising the nucleosome, this structure is a chromatosome. In the solenoid structure, the nucleosomes fold up and are stacked, forming a helix.

The key concept in magnetic confinement fusion is that ions and electrons in a plasma will rotate around magnetic lines of force. A simple way to confine a plasma would be to use a solenoid, a series of circular magnets mounted along a cylinder that generates uniform lines of force running down the long axis of the cylinder. A plasma generated in the center of the cylinder would be confined to run along the lines down the inside of the tube, keeping it away from the walls. However, it would be free to move along the axis and out the ends of the cylinder.
|
|
One can close the ends by bending the solenoid around into a circle, forming a torus (a ring or donut). In this case, the particles will still be confined to the middle of the cylinder, and even if they move along it they would never exit the ends - they would circle the apparatus endlessly. However, Fermi noted a problem with this arrangement; consider a series of circular magnets with the toroidal confinement area threaded through their centers, the magnets will be closer together on the inside of the ring, with a stronger field. Particles in such a system will drift up or down across the torus.

There were also further costs and delays owing to engineering difficulties encountered while building the cavern for the Compact Muon Solenoid, and also due to magnet supports which were insufficiently strongly designed and failed their initial testing (2007) and damage from a magnet quench and liquid helium escape (inaugural testing, 2008) (see: Construction accidents and delays). Because electricity costs are lower during the summer, the LHC normally does not operate over the winter months, although exceptions over the 2009/10 and 2012/2013 winters were made to make up for the 2008 start-up delays and to improve precision of measurements of the new particle discovered in 2012, respectively.

When the required charge pressure has finally been calculated it is converted to the PWM signal that controls the solenoid valve, The ECU then controls that the actual pressure (measured by the pressure sensor) corresponds with the required pressure. If needed the PWM is fine tuned by multiplication of a correction factor. The correction factor (adaptation) is then stored in the memory of the ECU and is always used in the calculation of the PWM signal. The rationale with this is to make sure that the actual pressure as soon as possible will be equal to the required after a change of the load has occurred.

When the coolant temperature is warmer than +85°C or four minutes has passed the Heat Plates are switched off. To compensate for the increased air resistance in the intake, engines fitted with Heat Plates have a slightly adjusted charge pressure, Approximately: +0.2 bar, this means that LPT models with heat plates have a solenoid valve to raise the charging pressure above basic charging pressure. In case of a Heat Plate-failure the car may have drivability problems due condensed fuel in the intake during cold engine operations. This condensed fuel is compensated in engines without Heat Plates by enriching the A/F mixture.

When a vehicle passes over the loop or is stopped within the loop, some of the vehicle's ferrous body material increases the loop's inductance, in the same principle as including a metal core within a solenoid coil. However, the peripheral metal of the vehicle has an opposite effect on the inductance due to eddy currents that are produced. The decrease in inductance from the eddy currents more than offsets the increase from the ferrous mass of the engine, and the net effect is an overall reduction in the inductance of the wire loop. The decrease in inductance tends to decrease the electrical impedance of the wire to alternating current.

A shunt-trip unit appears similar to a normal breaker and the moving actuators are 'ganged' to a normal breaker mechanism to operate together in a similar way, but the shunt trip is a solenoid intended to be operated by an external constant voltage signal, rather than a current, commonly the local mains voltage or DC. These are often used to cut the power when a high risk event occurs, such as a fire or flood alarm, or another electrical condition, such as over voltage detection. Shunt trips may be a user fitted accessory to a standard breaker, or supplied as an integral part of the circuit breaker.

An "active" booster is a non "conventional" booster where a solenoid is used to open the booster air valve to automatically push the master cylinder forward to perform some forms of dynamic stability control. Brake boosters come in either a single diaphragm or tandem diaphragm (which is generally used for bigger vehicles and trucks). They can be "cabin- breathers" (taking clean filtered air from inside the cabin thus may be noisier) or "engine-breathers" (less noisy but more at risk for becoming clogged with mud/ice if not protected properly). Apart from this additional booster setup, the braking system is a normal hydraulic brake system.
|
|
This induces swirl of the intake charge which improves air/fuel atomization in the cylinder and allows for a leaner fuel mixture to be used. As the engine's speed and load increase, both valves are needed to supply a sufficient mixture. When engaging VTEC mode, a pre-defined threshold for MPH (must be moving), RPM and load must be met before the computer actuates a solenoid which directs pressurized oil into a sliding pin, just like with the original VTEC. This sliding pin connects the intake rocker arm followers together so that, now, both intake valves are following the "normal" camshaft lobe instead of just one of them.

A great advance in the RDF technique was introduced in the form of phase comparisons of a signal as measured on two or more small antennas, or a single highly directional solenoid. These receivers were smaller, more accurate, and simpler to operate. Combined with the introduction of the transistor and integrated circuit, RDF systems were so reduced in size and complexity that they once again became quite common during the 1960s, and were known by the new name, automatic direction finder, or ADF. This also led to a revival in the operation of simple radio beacons for use with these RDF systems, now referred to as non- directional beacons (NDB).

CLICdet consists of four main layers of increasing radius: vertex and tracking system, calorimeters, solenoid magnet, and muon detector. A silicon pixel detector prototype for CLIC: "CLICTD" – a monolithic CMOS chip containing both sensor and readout, shown here on an electronics board during testing. The vertex and tracking system is located at the innermost region of CLICdet and aims to detect the position and momenta of particles with minimum adverse impact on their energy and trajectory. The vertex detector is cylindrical with three double layers of detector materials at increasing radii and has three segmented disks at each end in a spiral configuration to aid air flow cooling.

Maxwell changed Faraday's phrase lines of force to tubes of force, when expressing his fluidic assumptions involved in his mathematization of Faraday's theories. A tube of force, also called a tube of electrostatic induction or field tube, are the lines of electric force which moves so that its beginning traces a closed curve on a positive surface, its end will trace a corresponding closed curve on the negative surface, and the line of force itself will generate an inductive tubular surface. Such a tube is called a "Solenoid". There is a pressure at right angles to a tube of force of one half the product of the dielectric and magnetic density.

The solenoid pack is mounted directly to the valve body; its connector protrudes from a hole on the left side of the transmission. On the 45 and 545RFE the hydraulic control system design (without electronic assist) provides the transmission with PARK, REVERSE, NEUTRAL, SECOND, and THIRD gears, based solely on driver shift lever selection. This design allows the vehicle to be driven (in “limp-in” mode) in the event of an electronic control system failure, or a situation that the Transmission Control Module (TCM) recognizes as potentially damaging to the transmission. On the 68RFE, fourth gear is used for limp-in instead of second and third.

Though this is true, the term is usually understood to refer to devices which involve an electrical signal to create mechanical movement, or vice versa mechanical movement to create an electric signal. Often involving electromagnetic principles such as in relays, which allow a voltage or current to control another, usually isolated circuit voltage or current by mechanically switching sets of contacts, and solenoids, by which a voltage can actuate a moving linkage as in solenoid valves. Before the development of modern electronics, electromechanical devices were widely used in complicated subsystems of parts, including electric typewriters, teleprinters, clocks, initial television systems, and the very early electromechanical digital computers.

Unfortunately, this arrangement would not confine the plasma along the length of the tube, and the plasma would be free to flow out the ends. The obvious solution to this problem is to bend the tube around into a torus (a ring or donut) shape. Motion towards the sides remains constrained as before, and while the particles remain free to move along the lines, in this case, they will simply circulate around the long axis of the tube. But, as Fermi pointed out, when the solenoid is bent into a ring, the electrical windings would be closer together on the inside than the outside.

The conception and construction of giant bubble chambers such as Gargamelle and BEBC was based on the know-how acquired through the construction and operation of smaller bubble chambers such as the 30 cm hydrogen chamber, which came into operation at CERN in 1960, and followed four years later by the 2 m hydrogen chamber. The BEBC project was launched in 1966 by CERN, France (Saclay) and Germany (DESY) and installed at CERN in the early 1970s. The chamber body was surrounded by the then largest superconducting solenoid magnet of two coils in a Helmholtz arrangement. The magnet coils were fabricated at CERN using copper reinforced Niob-Titanium superconductor cable.

A significant feature of the interlock is that the key is held or trapped in one position of the lock. Releasing the key indicates that the interlocked device has been made safe; the interlocked device cannot be re- energized until the key has been returned and operated to retract the bolt. Some complex sequences use key exchange blocks or boxes, that allow alternative sequences of operation. Interlock devices may have an electrical solenoid which holds the key until an electrical circuit is interrupted; for example, the power supply for a high-voltage cabinet has been de-energized, releasing a key to allow access to the interior of the cabinet.

The power levers should have prevented to move from flight idle to ground idle during flight by the function of Electric Magnetic Lock Systems and Mechanical Power Lever Stop Slot. At the accident aircraft was found that the electric magnetic lock system (Power Lever lock) was on open position. With power lever lock on open position, the solenoid of the electric magnetic lock system disengage and allow the power lever moves to ground idle in flight whenever the mechanical power lever stop slots lifted. Based on simulator test conducted by the NTSC, if the engine entered this condition, the aircraft would lose lift and eventually descended rapidly.

Towards the end of UA1, (1990) Virdee, with a few other colleagues, started planning an experiment based on a high field solenoid that would be able to identify the missing elements of the Standard Model (SM) and also to probe in full the physics of the TeV scale. This was to become the CMS experiment at the LHC, one of the most complex instruments science has ever seen. Since 1991 Virdee has played a crucial role in all phases of CMS. Over the last two decades this has covered conceptual design, intensive R&D;, prototyping, construction, installation, commissioning, data-taking and finally physics exploitation.

In drag racing, a transbrake is a mechanism that selectively places the transmission in first and reverse gears simultaneously, effectively holding the race car stationary as if the foot brake was applied. It is specifically used on automatic transmissions that employ a torque converter, where it is beneficial to build up hydraulic pressure before the vehicle is launched. The transbrake is activated by the driver by applying electric current to a solenoid at the transmission. With the transbrake engaged (transmission locked), the engine throttle can be increased to any position (opening) in preparation for launch without the race driver worrying about the car creeping forward.

An IEEE 1284 36-pin female on a circuitboard In the 1970s, Centronics developed the now-familiar printer parallel port that soon became a de facto standard. Centronics had introduced the first successful low-cost seven-wire print head, which used a series of solenoids to pull the individual metal pins to strike a ribbon and the paper. A dot matrix print head consists of a series of metal pins arranged in a vertical row. Each pin is attached to some sort of actuator, a solenoid in the case of Centronics, which can pull the pin forward to strike a ribbon and the paper.

The notching mechanism was located in the area occupied by the print mechanism on a 026 printing keypunch. It had a solenoid which drove the notching mechanism, and another that selected the top notch punch or end of card punch. When an operator keying data to be verified encountered an error, the operator was given a second and third try to re-enter the data that was supposed to be in the field. If the third try was incorrect an error notch was put on the top of the card over the column with the error and the "OK" punch at the end of the card was not enabled.

The goal was to detect and measure the stable particles that remain after colliding protons at nearly the speed of light, in an effort to investigate physics beyond the Standard Model and identify the conditions of the early universe. The CMS was constructed and is located at one of the four collision points that make up the LHC and is designed to detect muons with high accuracy and be the most powerful solenoid magnet of its time, being capable of producing a magnetic field of 4 Tesla. The international collaboration that was CMS would come to be one of the largest of its kind, incorporating over 200 institutes and 50 countries.

Console of the Organ, an electrically actuated lithophone The Great Stalacpipe Organ is an electrically actuated lithophone located in Luray Caverns, Virginia, USA. It is operated by a custom console that produces the tapping of ancient stalactites of varying sizes with solenoid-actuated rubber mallets in order to produce tones. The instrument's name was derived from the resemblance of the selected thirty-seven naturally formed stalactites to the pipework of a traditional pipe organ along with its custom organ-style keyboard console. It was designed and implemented in 1956 over three years by Leland W. Sprinkle inside the Luray Caverns near Shenandoah National Park in Virginia, USA.

An irrigation line with water timer A water timer is an electromechanical device that, when placed on a water line, increases or decreases the water flow through the use of an electro-mechanically actuated ball valve or embedded (solenoid) valve. It is used in conjunction with irrigation sprinklers to form an automated or non-automated sprinkler system, capable of administering precise amounts of water, at a regular basis. A water flow timer using a ball valve contains an electric motor with gears to stop or start the water flow by turning a perforated ball within the water flow line. The gearbox in a ball valve timer makes a rumbling sound when actuated.

However, this is only true if the magnetic field remains the same – beta is the ratio of magnetic to plasma density. If one imagines a toroidal confinement area wrapped with ring- shaped magnets, it is clear that the magnetic field is greater on the inside radius than the outside - this is the basic stability problem that the tokamak's electric current addresses. However, the difference in that field is a function of aspect ratio; an infinitely large toroid would approximate a straight solenoid, while an ST maximizes the difference in field strength. Moreover, as there are certain aspects of reactor design that are fixed in size, the aspect ratio might be forced into certain configurations.

The Overhauser effect magnetometer or Overhauser magnetometer uses the same fundamental effect as the proton precession magnetometer to take measurements. By adding free radicals to the measurement fluid, the nuclear Overhauser effect can be exploited to significantly improve upon the proton precession magnetometer. Rather than aligning the protons using a solenoid, a low power radio-frequency field is used to align (polarise) the electron spin of the free radicals, which then couples to the protons via the Overhauser effect. This has two main advantages: driving the RF field takes a fraction of the energy (allowing lighter-weight batteries for portable units), and faster sampling as the electron-proton coupling can happen even as measurements are being taken.

The IMP was a genuine mechanical computer. From the sole solenoid actuator's incremental motion, the horological mechanism derived irregular oscillating functions which in turn rotated the globe and varied its axis, and also moved its two cylindrical indicators for longitude and latitude. Some uncommon, intricate horological devices found in the IMP include cardioid-shaped cam discs, a cone-shaped cam cylinder with a cardioid cross-section and "mechanical rectifiers" which transformed an alternating motion into an analogous, but unidirectional motion (see illustrations). The only other electric actuator used in the IMP instrument was the motor used to fast-forward the mechanism from the actual point-to-nadir to the expected landing point, some 120 degrees further east.

This last action connected the flight sequencer system's impulses to the instrument's solenoid actuator. These impulses were then converted into a slow, regular mechanical advance which cascaded through the mechanical components, effecting the computations needed to move the globe and other indicators. Meanwhile, the instrument's variable resistor and cam-activated electric blade contacts modulated electrical signals from other electrical instruments through the spacecraft and its control systems, feeding them with an analog representation of the spacecraft's displacement relative to Earth coordinates. From a systems design perspective, it is remarkable, even in the early 1960s, that a mechanical system generated crucial, primary data to electrical and electronic control and telemetry systems through the spacecraft.

The loss of heat removal from the primary loop and the failure of the auxiliary system to activate caused the primary loop pressure to increase, triggering the pilot-operated relief valve at the top of the pressurizera pressure active-regulator tankto open automatically. The relief valve should have closed when the excess pressure had been released, and electric power to the solenoid of the pilot was automatically cut, but the relief valve stuck open because of a mechanical fault. The open valve permitted coolant water to escape from the primary system, and was the principal mechanical cause of the primary coolant system depressurization and partial core disintegration that followed.Walker, pp. 73–74.

They are generally designed using manual transmission "internals", and when used in passenger cars, have synchromesh operated helical constant mesh gear sets. Early semi-automatic systems used a variety of mechanical, electrical, pneumatic, and hydraulic systems—including centrifugal clutches, vacuum- operated clutches, torque converters, electro-pneumatic clutches, electro- mechanical (and even electrostatic) and servo/solenoid-controlled clutches, and control schemes—automatic clutching when moving the gearshift, pre- selector controls, centrifugal clutches with drum-sequential shift requiring the driver to lift the throttle for a successful shift, etc.—and some were little more than regular lock-up torque converter automatics with manual gear selection. Semi-automatic transmission systems on motorcycles typically use a centrifugal clutch.

An ensemble of cylindrical barrel detectors that surround the nominal interaction point is used to track all the particles that fly out of the hot, dense medium. The Inner Tracking System(ITS) (consisting of three layers of detectors: Silicon Pixel Detector(SPD), Silicon Drift Detector(SDD), Silicon Strip Detector(SSD)), the Time Projection Chamber(TPC) and the Transition Radiation Detector(TRD) measure at many points the passage of each particle carrying an electric charge and give precise information about the particle's trajectory. The ALICE barrel tracking detectors are embedded in a magnetic field of 0.5 Tesla produced by a huge magnetic solenoid bending the trajectories of the particles. From the curvature of the tracks one can derive their momentum.

The nuclear pore complex is an extremely large protein complex that mediates transit into and out of the cell nucleus. Homologous structures from which the NPC might have evolved have not been detected in prokaryotic transmembrane transport proteins; however, it has been suggested that the NPC components show distinct homology to vesicle coat proteins found in clathrin/adaptin, COPI, and COPII complexes. Most distinctively, a shared domain architecture consisting of an N-terminal beta propeller and a C-terminal alpha solenoid has been detected in both NPC and coat proteins, suggesting a possible common origin. An ancestral "protocoatomer" that diversified to acquire derived characteristics of all four modern complexes has been proposed.

For 2013 the Multistrada 1200 had changes including the addition of an active suspension system, using solenoid/valve actuated methods to actively control damping rates, often called the "Sky-Hook method". The bike also had a revised second generation of the Testastretta 11-degree motor, now with "twin- plug cylinder heads for smoother, more efficient combustion", the change contributing to a 5% increase in torque and a 10% improvement in fuel consumption. Also, there are significant changes to the windscreen, which is "larger and shaped to reduce noise at high speed". A new Granturismo model has larger side-cases, the addition of a top case, driving lights and more touring-oriented tires.

Spindle speeds can range from 30,000 RPM to 100,000 RPM depending on the milling system, with higher spindle speeds equating to better accuracy, in a nutshell the smaller the tool diameter the higher RPM you need. Typically this drive system comprises non-monitored stepper motors for the X/Y axis, an on-off non-monitored solenoid, pneumatic piston or lead screw for the Z-axis, and a DC motor control circuit for spindle speed, none of which provide positional feedback. More advanced systems provide a monitored stepper motor Z-axis drive for greater control during milling and drilling as well as more advanced RF spindle motor control circuits that provide better control over a wider range of speeds.

This would prove to be a one-off exercise (due to the difficulty of acquiring brand new Rover V8s at the time.) left The first major alteration to the M-series body was the hatchback Taimar, introduced at the October 1976 British International Motor Show and using the same mechanicals as the 3000M. The name was inspired by the name of Martin's friend's girlfriend, Tayma. The opening hatchback alleviated the previous difficulty of maneuvering luggage over the seats to stow it in the cargo area, and the hatch itself was opened electrically via a solenoid-actuated latch triggered by a button on the driver's doorjamb. Over its three-year production, a total of 395 normally aspirated Taimars were built.

Depending on the collet design, it can be either pulled (via a threaded section at the rear of the collet) or pushed (via a threaded cap with a second taper) into a matching conical socket to achieve the clamping action. As the collet is forced into the tapered socket, the collet will contract, gripping the contents of the inner cylinder. (The axial movement of cones is not mandatory, however; a split bushing squeezed radially with a linear force—e.g., set screw, solenoid, spring clamp, pneumatic or hydraulic cylinder—achieves the same principle without the cones; but concentricity can only be had to the extent that the bushing's diameters are perfect for the particular object being held.

The original 6020 Central Unit provided track power & generated locomotive commands but required a separate 6035 locomotive Control 80 with speed controller, keypad for decoder address, Function / Off buttons, and Start / Stop buttons to switch track power. The red Stop button was provided as an emergency stop to immediately halt all trains. A two digit display showed the selected locomotive address (01 - 80). Solenoid devices, such as turnouts, were controlled by the 6040 Keyboard. Up to ten controllers could be added to the right hand side of the Central Unit, and up to 16 keyboards could be added to the left hand side, with each keyboard controlling 16 accessories (signals, turnouts, lights, etc.) for a total of 256.

The shot is interrupted when Captains Scarlet and Blue pass through a doorway as it was impossible to film this action in one motion. Supermarionation, a technique by which the movements of the puppets' mouths were electronically synchronised with pre- recorded dialogue, was first used during the production of Four Feather Falls in 1960. In all series prior to Captain Scarlet, a puppet's head had been disproportionately large compared to the rest of its body, as the head contained the solenoid that formed the key element of the lip-synch mechanism. Scaling the body up to match the head was not possible, as this would have made the puppets difficult to operate and required enlarging all the puppet sets.

In physics, a Dirac string is a hypothetical one-dimensional curve in space, conceived of by the physicist Paul Dirac, stretching between two Dirac monopoles with opposite magnetic charges, or from one magnetic monopole out to infinity. The gauge potential cannot be defined on the Dirac string, but it is defined everywhere else. The Dirac string acts as the solenoid in the Aharonov–Bohm effect, and the requirement that the position of the Dirac string should not be observable implies the Dirac quantization rule: the product of a magnetic charge and an electric charge must always be an integer multiple of 2\pi. Also, a change of position of a Dirac string corresponds to a gauge transformation.

Common rail (CR) direct injection systems do not have the fuel metering, pressure-raising and delivery functions in a single unit, as in the case of a Bosch distributor- type pump, for example. A high-pressure pump supplies the CR. The requirements of each cylinder injector are supplied from this common high pressure reservoir of fuel. An Electronic Diesel Control (EDC) controls both rail pressure and injections depending on engine operating conditions. The injectors of older CR systems have solenoid-driven plungers for lifting the injection needle, whilst newer CR injectors use plungers driven by piezoelectric actuators, that have fewer moving mass and therefore allow even more injections in a very short period of time.

Thunderbirds, Captain Scarlet and the Mysterons and Fireball XL5 on display at the National Media Museum in Bradford, UK Supermarionation (a blend of the words "super", "marionette" and "animation")La Rivière 2009, p. 67. was a style of television and film production employed by British company AP Films (later Century 21 Productions) in its puppet TV series and feature films of the 1960s. They were created by Gerry and Sylvia Anderson and filmed at APF's studios on the Slough Trading Estate. The characters in these productions were played by electronic marionettes with a moveable lower lip, which opened and closed in time with pre-recorded dialogue by means of a solenoid in the puppet's head or chest.

If the handle is circular with the stem as the axis of rotation in the center of the circle, then the handle is called a handwheel. Valves can also be controlled by actuators attached to the stem. They can be electromechanical actuators such as an electric motor or solenoid, pneumatic actuators which are controlled by air pressure, or hydraulic actuators which are controlled by the pressure of a liquid such as oil or water. Actuators can be used for the purposes of automatic control such as in washing machine cycles, remote control such as the use of a centralised control room, or because manual control is too difficult such as when the valve is very large.

He has been involved in a number of videos dedicated to disseminating discoveries in particle physics, and since July 7, 2011, has been a keynote speaker for a series produced by Fermilab that explores the range of issues dominating particle physics today in an accessible, and sometimes humorous way. Among the topics included in the series are the Higgs boson, antimatter, the nature of neutrinos, the concepts of the Big Bang, cosmic inflation, the multiverse, leptogenesis, and supersymmetry. After years of being involved in research using the DZero detector at the Fermilab Tevatron, he joined the Compact Muon Solenoid (CMS) experiment on the Large Hadron Collider at CERN, Geneva, Switzerland. Lincoln has co-authored more than 900 CMS papers.

The fourth element of control, the activator, is the corrective action taken to return the system to its expected output. The actual person, device, or method used to direct corrective inputs into the operating system may take a variety of forms. It may be a hydraulic controller positioned by a solenoid or electric motor in response to an electronic error signal, an employee directed to rework the parts that failed to pass quality inspection, or a school principal who decides to buy additional books to provide for an increased number of students. As long as a plan is performed within allowable limits, corrective action is not necessary; however, this seldom occurs in practice.

When the solenoid valve is actuated, air that normally holds the hammer in the full-back position is re-routed through the ram assembly and now drives the hammer forward at a rapid rate. The hammer then pins open the valve for a period of 6-16ms (this time is called the dwell). Since the marker's bolt is linked to the hammer, it travels forward at the same time carrying a paintball forward, passed the detents, into the firing position. Air travelling upwards through the, now open, valve is routed through the bolt and the paintball is shot out the barrel through a combination of air pressure and kinetic energy imparted from the bolt movement.

In 2009 Fiat Powertrain introduced the third generation of this technology, called Multijet II. With its new and innovative injectors with hydraulically balanced solenoid valve and even higher injection pressure of 2,000 bar (29,000 psi) it is capable of even more precise controlling of the injected diesel fuel, injecting it in a quicker and more flexible manner. It enables up to eight consecutive injections per combustion cycle and implemented Injection Rate Shaping technology, which provides two very close pilot injections making the fuel delivery more continuous and modulated. This results in an engine that is quiet and has a smoother operation, lower emissions, better fuel mileage and higher performance compared to the previous generation.

Later Cline was also a member of the Fermilab experiment that discovered the top quark and of one of the CERN experiments that discovered the Higgs boson in 2012. At UCLA he was also one of the pioneers of the use of liquefied noble gases as particle detectors and made innovative contributions to the development of the use of liquid argon and xenon to detect dark matter. In the early 1990s, the U.S. had plans to build the Superconducting Supercollider. Cline was among many other U.S. scientists who chose to work on a competing European based supercollider, CERN’s Large Hadron Collider . He continued working at CERN’s LHC and was a cofounder of the Compact Muon Solenoid (CMS) experiment.

Mu2e project logo A prototype of the Mu2e Transport Solenoid module Mu2e, or the Muon-to-Electron Conversion Experiment, is a particle physics experiment at Fermilab in the US. The goal of the experiment is to identify physics beyond the Standard Model, namely, the conversion of muons to electrons without the emission of neutrinos, which occurs in a number of theoretical models. Project co-spokesperson Jim Miller likens this process to neutrino oscillation, but for charged leptons. Observing this process will help to narrow the range of plausible theories. The experiment will be 10,000 times more sensitive than previous muon to electron conversion experiments, and probe energy scales up to 10,000 TeV.

Variable Cylinder Management (VCM) is Honda's term for its variable displacement technology, which saves fuel by using the i-VTEC system to disable one bank of cylinders during specific driving conditions—for example, highway driving. The 2008–12 Accords took this a step further, allowing the engine to go from 6 cylinders, down to 4, and further down to 3 as the computer sees fit. Unlike the pushrod systems used by DaimlerChrysler's Multi- Displacement System and General Motors' Active Fuel Management, Honda's VCM uses overhead cams. A solenoid unlocks the cam followers on one bank from their respective rockers, so the cam follower floats freely while the valve springs keep the valves closed.

Snap action control systems are often run with electricity, where a stand-alone thermostat acting as a switch is activated by the capillary bulb fluid. The thermostat switches an electrical signal on-or-off to an associated solenoid valve, controlling gas flow to the burner. This construction allows integration of other control mechanisms into the system, such as pilot flame failure, but requires the use of components known to be sensitive to high temperatures and water damage. Solenoids and associated wiring are known to degrade over time, even if operating within their design parameters, due to the cumulative effects of thermal cycling and ambient grease and oil coating their surfaces – environmental aspects known to attack the integrity of plastics.

The "AN" stands for "Army/Navy", since the gun was developed jointly for use by both services. The AN/M2 designation was also used for other aircraft guns and therefore it is important to write the caliber before the designation. The 12.7 mm AN/M2 had a cyclic rate of 600–800 rounds per minute, with the ability to be fired from an electrically operated remote-mount solenoid trigger when installed as a fixed gun. Cooled by the aircraft's slip-stream, the air-cooled 12.7 mm AN/M2 was fitted with a substantially lighter length barrel, reducing the weight of the complete unit to , which also had the effect of increasing the rate of fire.

Advertisements, jingles, and the top-of-hour station identification required by law were commonly stored on Fidelipac endless-loop tape cartridges, known colloquially as "carts". These were similar to the consumer four-track tapes sold under the Stereo-Pak brand, but had only two tracks and were usually recorded and played at 7.5 tape inches per second (in/s) compared to Stero-Pak's slower 3.75 in/s. The carts had a slot for a pinch roller on a spindle which was activated by solenoid upon pressing the start button on the cart machine. Because the capstan was already spinning at full speed, tape playback commenced without delay or any audible "run-up".

The ECU – working with another duty solenoid and vacuum diaphragm – determines the amount that the exhaust control valve opens. The ECU calculates this amount of valve opening based on the input of a differential pressure sensor that takes feeds from the intake manifold and the outlet of the secondary turbo. Any boost pressure produced by the secondary turbocharger during the transitional stage is redirected to the atmospheric side of the compressor inlet (between the turbos and air filter). With the primary turbo continuing to supply manifold pressure and the secondary turbocharger essentially bleeding off the boost it makes during the transition, the ECU will determine when to close the pressure relief valve and fully open the exhaust control valve.

The first electrical gear shift mechanism sold on new automobiles was the Vulcan electric gear shift system, a solenoid-driven transmission shift device for a standard sliding gear gearbox introduced in the summer of 1913. Among the automakers to offer the Vulcan system were the Haynes Automobile Company of Kokomo, Indiana the S.G.V. Company of Reading, Pennsylvania and the Norwalk Motor Car Company of Martinsburg, West Virginia. While the Vulcan shifter was often advertised as standard equipment on the Haynes car, a common floor shift was also available for $200 less. Norwalk made the Vulcan system available on their products, such as the Underslung Six, as an option; approximately 25 of those cars were so equipped.

By varying the amount of RF heating energy and plasma, VASIMR is claimed to be capable of generating either low-thrust, high–specific impulse exhaust or relatively high-thrust, low–specific impulse exhaust. The second phase of the engine is a strong solenoid-configuration electromagnet that channels the ionized plasma, acting as a convergent-divergent nozzle like the physical nozzle in conventional rocket engines. A second coupler, known as the Ion Cyclotron Heating (ICH) section, emits electromagnetic waves in resonance with the orbits of ions and electrons as they travel through the engine. Resonance is achieved through a reduction of the magnetic field in this portion of the engine that slows the orbital motion of the plasma particles.

How the read-write head is applied on the floppy Visualization of magnetic information on floppy disk (image recorded with CMOS-MagView)A spindle motor in the drive rotates the magnetic medium at a certain speed, while a stepper motor-operated mechanism moves the magnetic read/write heads radially along the surface of the disk. Both read and write operations require the media to be rotating and the head to contact the disk media, an action originally accomplished by a disk-load solenoid. Later drives held the heads out of contact until a front-panel lever was rotated (-inch) or disk insertion was complete (-inch). To write data, current is sent through a coil in the head as the media rotates.

Computer Controller Acoustic Instruments pt.2 features acoustic sounds such as prepared piano, drums, and wood and metal percussion, controlled electronically. James considers it the successor to his 2001 album Drukqs: > Part 1 is Drukqs, as that was the first thing I released that utilised > computer controlled instruments, namely a modified Yamaha Disklavier, 2nd > gen and a couple of midi controlled solenoid based drum mechanisms I made > just after I got the Disklavier. The EP extends the ideas of its predecessor, according to Mark Richardson of Pitchfork, who noted that "where James used to offer his electro-acoustic pieces as a showcase for lyrical melodies, about half the music here consists of crisply arranged beats, with loping drum lines that occasionally veer toward funk".

The technology is now transferred to private industries located in Chandigardh and Hyderabad for mass manufacturing. RCI at DRDO Missile Complex, Hyderabad is now supplying technology of brushless DC motors (BLDC) used for missile actuators and high response solenoid valves used in missile control for ventilator pumps that validated the prototype testing stages. Centre for Fire, Explosive and Environment Safety (CFEES) developed two sanitising equipments of 50 litres tank capacity consists of portable backpack type that covers an area of 300 metres while another trolley mounted for large area sanitisation of up to 3000 metres by spraying 1% hypochlorite solution. Vehicle Research and Development Establishment (VRDE) developed portable disinfection chamber and special face protection mask for health professionals combating COVID-19 outbreak in India.

The control system included a pneumatic system and a solid-state electrical sequence controller packaged with spark exciters for the gas generator and the thrust chamber spark plugs, plus interconnecting electrical cabling and pneumatic lines, in addition to the flight instrumentation system. The pneumatic system consisted of a high-pressure helium gas storage tank, a regulator to reduce the pressure to a usable level, and electrical solenoid control valves to direct the central gas to the various pneumatically controlled valves. The electrical sequence controller was a completely self- contained, solid-state system, requiring only DC power and start and stop command signals. Pre-start status of all critical engine control functions was monitored in order to provide an "engine ready" signal.

The spinning flywheel is then connected to the main engine and its inertia turns it over to start it. These stages are commonly automated by solenoid switches, with the machine operator using a two-position control switch, which is held in one position to spin the motor and then moved to the other to cut the current to the motor and engage the flywheel to the engine. The advantage of the inertia starter is that, because the motor is not driving the engine directly, it can be of much lower power than the standard starter for an engine of the same size. This allows for a motor of much lower weight and smaller size, as well as lighter cables and smaller batteries to power the motor.

Many such devices contain non-functional circuitry or naively constructed approximations of radio transmitters. A few do have functional circuitry, putting out a weak signal with a function generator or a simple timer circuit, but are still largely useless in comparison with a coil-based metal detector; others have been found to contain intentionally obfuscated or completely superfluous components (from individual components such as inductors or ribbon cables up to, in some cases, pocket calculators), often indicative of intentional fraud, incompetence, or both, by the designer. Such functioning circuitry as exists in such devices usually has no obvious way (motor, solenoid, etc.) to connect to any rotating joint in the device either, meaning the devices are often entirely dependent on the ideomotor effect to function.

The head assembly moved by actuating a damped solenoid movement, eliminating all belt drives and other wearable parts. These machines rivaled the Nakamichi in frequency and dynamic range. The B710MKII also achieved 20–20,000 Hz and dynamics of over 72 dB with Dolby C on chrome and slightly less dynamic range, but greater headroom with metal tapes and Dolby C. Revox adjusted the frequency range on delivery with many years of use in mind: when new, the frequency curve went upwards a few dB at 15–20 kHz, aiming for flat response after 15 years of use, and headwear to match. A last step taken by Revox produced even more-advanced cassette drives with electronic fine tuning of bias and equalization during recording.

This, in turn, allows wind pressure to activate a bellows or "pneumatic" which operates a larger valve. This valve causes a change of air pressure within a channel that leads to all pipes of that note. A separate "stop action" system is used to control the admittance of air or "wind" into the pipes of the rank or ranks selected by the organist's selection of stops, while other ranks are "stopped" from playing. The stop action can also be an electro-pneumatic action, or may be another type of action This pneumatically assisted valve action is in contrast to a direct electric action in which each pipe's valve is opened directly by an electric solenoid which is attached to the valve.

Post First World War German fighters were fitted with electrical synchronizers. In such a gear, a contact or set of contacts, either on the propeller shaft itself, or some other part of the drive train revolving at the same number of revolutions per minute, generates a series of electrical pulses, which are transmitted to a solenoid driven trigger motor at the gun. Experiments with these were underway before the end of the war, and again the LVG company seems to have been involved: a British intelligence report from 25 June 1918 mentions an LVG two-seater fitted with such a gear that was brought down in the British lines. It is known that LVG built 40 C.IV two-seaters fitted with a Siemens electrical synchronizing system.

In another example, a paper in the February 11, 2011 issue of Nature Physics describes creation and measurement of long-lived magnetic monopole quasiparticle currents in spin ice. By applying a magnetic-field pulse to crystal of dysprosium titanate at 0.36 K, the authors created a relaxing magnetic current that lasted for several minutes. They measured the current by means of the electromotive force it induced in a solenoid coupled to a sensitive amplifier, and quantitatively described it using a chemical kinetic model of point-like charges obeying the Onsager–Wien mechanism of carrier dissociation and recombination. They thus derived the microscopic parameters of monopole motion in spin ice and identified the distinct roles of free and bound magnetic charges.

The APC controls boost pressure and the overall performance, specifically the rate of rise and maximum boost level - and it detects and manages harmful knock events. To control the turbocharger, the APC monitors the engine's RPM and inlet manifold pressure via a pressure transducer, and uses these inputs to control a solenoid valve that trims the rate of rise of pressure as well as the maximum pressure by directing boost pressure to the turbocharger's pneumatic wastegate actuator. To detect knock, a piezoelectric knock sensor (basically a microphone) bolted to the engine block responds to unique frequencies caused by engine knock. The sensor generates a small voltage that is sent to the electronic control unit, which processes the signal to determine if, in fact, knock is occurring.

The inner solenoid produces a two tesla magnetic field surrounding the Inner Detector. This high magnetic field allows even very energetic particles to curve enough for their momentum to be determined, and its nearly uniform direction and strength allow measurements to be made very precisely. Particles with momenta below roughly 400 MeV will be curved so strongly that they will loop repeatedly in the field and most likely not be measured; however, this energy is very small compared to the several TeV of energy released in each proton collision. The outer toroidal magnetic field is produced by eight very large air-core superconducting barrel loops and two end-caps air toroidal magnets, all situated outside the calorimeters and within the muon system.

The fact that the weapon only fed from a drum containing 1,500 rounds of ammunition meant that a slower rate of fire was desired.United States, 1969. p. G-1 The second set of subvariants, designated XM18E1 (and standardized as the M18) and SUU-11A/A, featured an aircraft-to-pod electric connection, allowing aircraft internal power to be used in providing better starting torque, a de-energized solenoid allowing for better round clearing at low rates of fire, and circuitry that allowed for selectable rates of fire. The options were either 2,000 rpm or 4,000 rpm, both significantly lower than the base rate of fire.United States, 1969. p. G-3 The last set of subvariants were designated M18A1 (development of the M18E1) and SUU-11B/A.

Electronically controlled transmissions may behave differently, as engaging a gear at speed is essentially undefined behavior. Some modern transmissions have a safety mechanism that will resist putting the car in reverse when the vehicle is moving forward; such a mechanism may consist of a solenoid-controlled physical barrier on either side of the reverse position, electronically engaged by a switch on the brake pedal, so that the brake pedal needs to be depressed in order to allow the selection of reverse. Some electronic transmissions prevent or delay the engagement of reverse gear altogether while the car is moving. : Some shifters with a shift button allow the driver to freely move the shifter from R to N or D without actually depressing the button.

Since open loop systems do not modify control levels based on MAP sensor, differing boost pressure levels may be reached based on outside variables such as weather conditions or engine coolant temperature. For this reason, systems that do not feature closed loop operation are not as widespread. Boost controllers often use pulse width modulation (PWM) techniques to bleed off boost pressure on its way to the reference port on the wastegate actuator diaphragm in order to (on occasion ) under report boost pressure in such a way that the wastegate permits a turbocharger to build more boost pressure in the intake than it normally could. In effect, a boost- control solenoid valve lies to the wastegate under the engine control unit´s (ECU) control.

For a single layer solenoid, the distributed capacitance will mostly lie between adjacent turns as shown in figure 4 between turns T1 and T2, but for multiple layer windings and more accurate models distributed capacitance to other turns must also be considered. This model is fairly difficult to deal with in simple calculations and for the most part is avoided. The most common approach is to roll up all the distributed capacitance into one lumped element in parallel with the inductance and resistance of the coil. This lumped model works successfully at low frequencies but falls apart at high frequencies where the usual practice is to simply measure (or specify) an overall Q for the inductor without associating a specific equivalent circuit.

At the switch point a solenoid is actuated that allows oil pressure from a spool valve to operate a locking pin which binds the high RPM rocker arm to the low RPM ones. From this point on, the valves open and close according to the high-lift profile, which opens the valve further and for a longer time. The switch-over point is variable, between a minimum and maximum point, and is determined by engine load. The switch-down back from high to low RPM cams is set to occur at a lower engine speed than the switch-up (representing a hysteresis cycle) to avoid a situation in which the engine is asked to operate continuously at or around the switch-over point.

Magnet structure of the first ARC-ECRIS prototype constructed at JYFL Accelerator Laboratory ARC-ECRIS is an Electron Cyclotron Resonance Ion Source based on arc-shaped coils unlike the conventional ECRIS which bases on a multipole magnet (usually a hexapole magnet) inside a solenoid magnet. First time the arc-shaped coils were used already in the 1960s in fusion experiments, for example at the Lawrence Livermore National Laboratory (MFTF, Baseball II, ...) and later in Japan (GAMMA10, ...). In 2006 the JYFL ion source group designed, constructed and tested similar plasma trap to produce highly charged heavy ion beams. The first tests were promising and showed that a stable plasma can be confined in an arc-coil magnetic field structure (see references).

The aforementioned 4C eye and laser 4C eye systems which uses two additional sensors to calculate the amount of time it takes for a ball to be fully loaded into the breach and tells the board to pre-charge the solenoid. This helps increase rate of fire in semi-auto and allows for more uniform streams of paint. Protege users can buy the same pillow bolt that comes stock in the Vice from Bob Long Direct; it uses a rubber insert in the bolt face to put less pressure on the paintball being fired and to prevent paint from breaking inside the barrel. Lurker paintball makes an adjustable ram for the Gen 5 markers to help reduce recoil and lower dwell, thus increasing efficiency.

The lenses of a TEM are what gives it its flexibility of operating modes and ability to focus beams down to the atomic scale and magnify them back up to get an image on a camera. A lens is usually made of a solenoid coil nearly surrounded by ferromagnetic materials designed to concentrate the coil's magnetic field into a precise, confined shape. When an electron enters and leaves this magnetic field, it spirals around the curved magnetic field lines in a way that acts very much as an ordinary glass lens does for light—it is a converging lens. But, unlike a glass lens, a magnetic lens can very easily change its focusing power simply by adjusting the current passing through the coils.

On entering the detector solenoid, the muons will hit (and stop within) an aluminum target that is about 0.2 mm thick, entering orbitals around nuclei within the target. Any muons which convert into electrons without emitting neutrinos will escape these orbitals and enter the detector with a characteristic energy of around 105 MeV. The detector itself consists of two components: a straw tracker to measure the momentum of outgoing particles; and an electromagnetic calorimeter to identify which particle interactions to record for further study, identify what type of particle passed through the tracker, and to confirm the measurements of the tracker. An electron with energy of around 105 MeV will indicate that the electron originated in a neutrinoless muon conversion.

The pin tip is the point of highest resistance at which point an arc is drawn, melting the solder flux whilst simultaneously heating the lug material and the surface of the structure or pipeline to the required soldering temperature. After approximately 1.5 seconds the circuit is mechanically or electronically broken, the solenoid is de-energised and the brazing pin is pushed forward into the molten pool of brazing alloy. The pin tip, brazing alloy, flux and lug cool into a homogenous unit. The pin brazing process is well suited for joints between insulated pipe sections, connection to measuring cables, installation of sacrificial anodes and bonding zinc bracelets to offshore pipelines, due to the ease and speed of installation, high mechanical strength and extremely low resistance.

Where reactive loads are present, such as with capacitors or inductors, energy storage in the loads results in a phase difference between the current and voltage waveforms. During each cycle of the AC voltage, extra energy, in addition to any energy consumed in the load, is temporarily stored in the load in electric or magnetic fields then returned to the power grid a fraction of the period later. Electrical circuits containing predominantly resistive loads (incandescent lamps, heating elements) have a power factor of almost 1, but circuits containing inductive or capacitive loads (electric motors, solenoid valves, transformers, fluorescent lamp ballasts, and others) can have a power factor well below 1. In the electric power grid, reactive loads cause a continuous "ebb and flow" of nonproductive power.

Additionally, leg levelers that are all extended fully make the game easier to nudge; when collapsed low, the entire game is more stable, and nudging becomes harder. The ball is put into play by use of the plunger, a spring-loaded rod that strikes the ball as it rests in an entry lane, or as in some newer games, by a button that signals the game logic to fire a solenoid that strikes the ball. With both devices the result is the same: The ball is propelled upwards onto the playfield. Once a ball is in play, it tends to move downward towards the player, although the ball can move in any direction, sometimes unpredictably, due to contact with objects on the playfield or by the player's own actions.

The engine was a new rubber-hydro mounted all-aluminium alloy 4.2-litre 40-valve (five valves per cylinder) 90° V8 (parts code: 077, identification codes: AQJ [Sept 99-May 1], ANK [Sept 00-onwards]). It had double overhead camshafts on each cylinder bank and solenoid-operated magnesium two-stage variable intake manifold. It displaced , and was rated at at 6,600 rpm, producing of torque at 3,400 rpm. It satisfied the European Union EU3 emissions standard, and was managed by a Bosch Motronic ME 7.1.1 electronic engine control unit (ECU) with manifold- sited sequential fuel injection, mapped direct ignition with eight individual spark coils, Bosch longlife spark plugs, four heated lambda sensors and two catalytic converters, cylinder-selective knock control and a Bosch "E-Gas" drive by wire throttle.

He was born in Casola in Lunigiana, Italy, on November 8, 1950. He received his degree in physics in 1975 at the University of Pisa, Italy where he becomes professor in 1992. Since 1976 he works in the field of high energy physics, participating in CERN experiments NA1, NA7 and ALEPH, and in the CDF experiment at Fermilab, Batavia (IL-USA). Among his contributions there are the first precision measurements of the lifetime of charmed mesons, precision tests of the Standard Model of the fundamental interactions, search for the Higgs boson, and for various signatures of Supersymmetry or new physics beyond the Standard Model. Since the beginning of the '90 his activity is mainly devoted to the Compact Muon Solenoid (CMS), experiment proposed for the Large Hadron Collider (LHC) at CERN, Geneva, (Switzerland).

The success of the Eindecker led to numerous gun synchronization devices, culminating in the reasonably reliable hydraulic British Constantinesco gear of 1917. By the end of the war German engineers were well on the way to perfecting a gear using an electrical rather than a mechanical or hydraulic link between the engine and the gun, with the gun being triggered by a solenoid rather than by a mechanical "trigger motor". From 1918 to the mid-1930s the standard armament for a fighter aircraft remained two synchronized rifle-calibre machine guns, firing forward through the arc of the propeller. During the late 1930s, however, the main role of the fighter was increasingly seen as the destruction of large, all-metal bombers, for which the "traditional" light armament was inadequate.

One fully loaded IBM 2841 Control Unit connected with eight IBM 2321 Data Cell Devices has the capacity of 441 IBM 2311 Disk Devices, which would need to be connected to 56 IBM 2841 Control Units, which would require seven data channels. The Data Cell makes use of three concurrently operating separate seeking systems: a servo-hydraulic one to rotate the bins to select the proper subcell, and two solenoid driven ones: one to select the correct strip tab of the ten in the subcell, and the other to select one of the five head positions, for the 20 element head (100 tracks per strip). The hydraulic fluid, Mobil DTE Light, a machine tool circulating oil, is pressurized at 1500 psi and despite a lot of folklore about oil leaks, they were very rare.

These holes were replaced in the 1960s with full cone nozzles. These nozzles were carefully selected to accurately approximate (1) the size of a rainfall water drop, (2) the velocity of a drop as it strikes the ground, and (3) the uniformity of drops across a plot to assure an accurate simulation of rainfall. Simulators of the 1960s era could only simulate a single rainfall intensity; however, by the 1980s solenoid valves could modulate the water flow to dynamically vary the intensity of simulated rainfall, much the same way the intensity of rainfall varies naturally in a storm. As rainfall simulation technology matured in the early 1990s, rainfall simulators were used in the United States as part of Water Erosion Prediction Project to update the universal soil loss equation.

Ignition switch on a Saab 9-5 An ignition switch, starter switch or start switch is a switch in the control system of a motor vehicle that activates the main electrical systems for the vehicle, including "accessories" (radio, power windows, etc.). In vehicles powered by internal combustion engines, the switch provides power to the starter solenoid and the ignition system components (including the engine control unit and ignition coil), and is frequently combined with the starter switch which activates the starter motor. Historically, ignition switches were key switches that requires the proper key to be inserted in order for the switch functions to be unlocked. These mechanical switches remain common in modern vehicles, further combined with an immobiliser to only activate the switch functions when a transponder signal in the key is detected.

The currents in the two conductors are therefore equal and opposite and cancel each other out. Any fault to earth (for example caused by a person touching a live component in the attached appliance) causes some of the current to take a different return path, which means that there is an imbalance (difference) in the current in the two conductors (single-phase case), or, more generally, a nonzero sum of currents from among various conductors (for example, three phase conductors and one neutral conductor). This difference causes a current in the sense coil (6), which is picked up by the sense circuitry (7). The sense circuitry then removes power from the solenoid (5), and the contacts (4) are forced apart by a spring, cutting off the electricity supply to the appliance.

The ECU then increases the amount of fuel injected by the injectors in order to obtain the required air-fuel ratio. Often a throttle position sensor (TPS) is connected to the shaft of the throttle plate to provide the ECU with information on whether the throttle is in the idle position, wide-open throttle (WOT) position, or somewhere in between these extremes. Throttle bodies may also contain valves and adjustments to control the minimum airflow during idle. Even in those units that are not "drive-by-wire", there will often be a small solenoid driven valve, the Idle Air Control Valve (IACV), that the ECU uses to control the amount of air that can bypass the main throttle opening to allow the engine to idle when the throttle is closed.

Typical output from a dot matrix printer operating in draft mode. This entire image represents an area of printer output approximately in size Epson VP-500 Printer with its cover removed Dot matrix printing uses a print head that moves back-and-forth, or in an up-and-down motion, on the page and prints by impact, striking an ink- soaked cloth ribbon against the paper, much like the print mechanism on a typewriter. However, unlike a typewriter or daisy wheel printer, letters are drawn out of a dot matrix, and thus, varied fonts and arbitrary graphics can be produced. Each dot is produced by a tiny metal rod, also called a "wire" or "pin", which is driven forward by the power of a tiny electromagnet or solenoid, either directly or through small levers (pawls).

Electrically operated display devices have developed from electromechanical systems for display of text, up to all-electronic devices capable of full- motion 3D color graphic displays. Electromagnetic devices, using a solenoid coil to control a visible flag or flap, were the earliest type, and were used for text displays such as stock market prices and arrival/departure display times. The cathode ray tube was the workhorse of text and video display technology for several decades until being displaced by plasma, liquid crystal (LCD), and solid-state devices such as thin-film transistors (TFTs), LEDs and OLEDs. With the advent of metal-oxide-semiconductor field-effect transistors (MOSFETs), integrated circuit (IC) chips, microprocessors, and microelectronic devices, many more individual picture elements ("pixels") could be incorporated into one display device, allowing graphic displays and video.

The first time close head-on remote photography had been used was in 1977 when photographer Richard Cooke, working with Sqn Ldr Alan Voyle, Senior Engineering Officer of The Red Arrows, developed a camera bracket to fit on the underside of a spare Red Arrows Folland Gnat aircraft. The pilots were carefully briefed on the ground and then, in the air, the photographer operated the camera from the back seat of the camera aircraft, using a mechanical release triggered by a solenoid, operated through the anti-collision light. The Nikkormat camera with autowind pointed back at the Red Arrows team and was fitted with a wide angle 24mm Nikkor lens. The photography was commissioned by the Telegraph Sunday Magazine and made the front cover on 3 July 1977.

Part of the mechanism includes a 60-tooth ratchet wheel advanced on every pendulum swing by a pawl driven by the electromagnet. Originally this operated a pair of contacts by two pins on its periphery to generate the half-minute pulses, but at some stage these contacts were removed. To the left of the pendulum is the regulator. This is arranged to apply a small force to the pendulum which through an ingenious linkage effectively works against gravity, slowing the pendulum down. The force comes from a torque generated by a spiral hair-spring, one end being attached to the pivot of a lever that forms part of the escapement linkage, the other to a disk that can be rotated in small steps by a solenoid-operated “stepper motor”.

Present-day ethnomusicologists, such as Margaret Kartomi and Terry Ellingson, suggest that, in keeping with the spirit of the original Hornbostel Sachs classification scheme, if one categorizes instruments by what first produces the initial sound in the instrument, that only subcategory 53 should remain in the electrophones category. Thus, it has been more recently proposed, for example, that the pipe organ (even if it uses electric key action to control solenoid valves) remain in the aerophones category, and that the electric guitar remain in the chordophones category, and so on. Thus, in present-day ethnomusicology, an electrophone is considered to be only musical instruments which produce sound primarily by electrical means. It is usually considered to constitute one of five main categories in the Hornbostel-Sachs scheme of musical instrument classification, despite not being in the original scheme published in 1914.

The stop action magnet, usually abbreviated to SAM, is an electromagnetic device used for the control of pipe organs and virtual pipe organs, and forms part of the organ's combination action. On a classical organ the device may be referred to as a drawstop solenoid. The SAM can be considered an electrical relay, the difference being that the SAM also has a drawknob or a tab, which enables it to be operated manually as well as electrically. A SAM will have an armature which is operated by an electrically induced magnetic field and dependent on whether the SAM is being used with a drawknob or a tilting tablet on a classically voiced organ or with a flat tab on a theatre organ, the armature will move in either a linear fashion or with semi-circular movement, in a small defined arc.

While the modifications were intended to make the weapon more useful as a squad light machine gun, it was a stopgap solution. Even though it was reliable, it proved somewhat impractical for its intended role. While the 31 lb M1919A4 had a crew of two or more to carry the gun and the tripod, one M1919A6 gunner was expected to carry and deploy the gun by himself.The Five Worst Light Machine Guns (LMGs) - Defensemedianetwork.com, 4 September 2013 In the late 1950s, an M1919 designed for remote firing via a solenoid trigger was developed for use in the XM1/E1 armament subsystem was designated M37C. The US Navy later converted a number of M1919A4s to 7.62mm NATO chambering and designated them Mk 21 Mod 0; some of these weapons were employed in Vietnam in riverine warfare patrols.

A direct current flowing in a solenoid creates a strong magnetic field around a hydrogen-rich fluid (kerosine and decane are popular, and even water can be used), causing some of the protons to align themselves with that field. The current is then interrupted, and as protons realign themselves with the ambient magnetic field, they precess at a frequency that is directly proportional to the magnetic field. This produces a weak rotating magnetic field that is picked up by a (sometimes separate) inductor, amplified electronically, and fed to a digital frequency counter whose output is typically scaled and displayed directly as field strength or output as digital data. The relationship between the frequency of the induced current and the strength of the magnetic field is called the proton gyromagnetic ratio, and is equal to 0.042576 Hz nT−1.

Nitrogen is generally preferred over carbon dioxide for a few reasons. Nitrogen will not liquefy and leak into the marker, while if the CO2 tank does not have an anti-siphon tube installed, or if there is no expansion chamber or regulator, liquid CO2 can leak into the marker, causing damage to O-rings and dangerous overpressures. The solenoid valves on electro-pneumatic markers are particularly sensitive to this, and thus many manufacturers will specify to use only nitrogen or HPA with their electro-pneumatic markers. Because it is always controlled by 2 or more pressure regulators, Nitrogen generally has a more consistent shot velocity than CO2. This is because when the playing area is warm, the normally unregulated CO2 will expand more rapidly from the liquid form, causing the marker to fire at a higher velocity.

Shifting was originally via a large off-the-shelf electric solenoid (actually two solenoids inline which acted in opposite directions), but the windings for one of the internal solenoids burned out the Sunday before the VIR competition (the team left on the Tuesday morning after this). Parts were gathered from old (~10 years previous or more) pneumatic shifting setups that were stored in various places, and the following day CO2 tanks and various other parts were bought at a paint ball supply store and a pneumatic shifter was on the car by 4am Tuesday morning. This system used the same switches that actuated the original shifter, which were mounted on a collar on the steering shaft. The shift paddles pushed small pushrods which were in holes drilled in the quick release and protruded when the paddle was pulled to push the microswitch levers.

Volvo's answer to DSG goes by the name PowerShift, 2008-01-11Ford officially announces dual-clutch PowerShift gearbox for 2010, 2009-01-21 However, the new PowerShift gearbox used in the Ford Fiesta and Ford Focus used dry clutches and electric motor/solenoid actuation. The transmission proved problematic even before it was released, with all installed units exhibiting failure behavior such as slipping or surging during launches, poor shift quality, and uncommanded shifts into neutral resulting in loss of power. Investigations have revealed that Ford's engineers and management were aware of the transmission problems before and after launching, and knew that the transmission was not capable of achieving an acceptable operation, yet chose to use the transmission anyway. Production workers have stated that cars with this transmission exhibited problems on their first drive off of the production line.

CEC was unique in that almost all of its sensors and actuators were digital; instead of the usual analog throttle position, coolant temperature, intake temperature and manifold pressure sensors, it used a set of fixed pressure- and temperature-controlled switches (as well as a wide-open throttle switch on the carburetor) to control fuel mixture and ignition timing. The only analog sensor in the system was the oxygen sensor. In other respects, it was a typical "feedback" carburetor system of the early-1980s, using a stepper motor to control fuel mixture and a two-stage "Sole-Vac" (which used a solenoid for one stage, and a vacuum motor for the other) to control idle speed. The CEC also controlled ignition timing using information from the fuel-control section and an engine knock sensor on the intake manifold.

"Vladimir Teplyakov" Retrieved on December 12, 2009 From 1959 to 1966 he worked at Chelyabinsk-70 to develop a high-current proton linear accelerator for controlled thermonuclear fusion. In mid 60's, together with G.M. Anisimov, Teplyakov conceived the idea of focusing the charged particle beams by the radio-frequency (RF) accelerating electromagnetic field rather than by solenoid magnets. This work continued at the Institute for High Energy Physics (IHEP) in Protvino, where his group moved in 1966 to build the I-100, a 100 MeV Alvarez drift-tube linac, which was an injector to the U-70, a 70 GeV proton synchrotron, the world's largest particle accelerator at that time. By late 60's, Teplyakov and I.M. Kapchinsky developed the concept of the radio- frequency quadrupole (RFQ) where accelerating gaps are supplemented with spacer electrodes charged under an intermediate potential.

Lawrence Sulak is an American physicist, currently the David M. Myers Distinguished Professor at Boston University. Some of Sulak's research has included Higgs detection at the Compact Muon Solenoid in the Large Hadron Collider, neutrino physics, astrophysics, and contributing work for the Monopole, Astrophysics and Cosmic Ray Observatory. The 1986 book _Second Creation_ on the history of modern particle physics by Robert Crease and Charles Mann opened with a description of being escorted by Larry Sulak down to the experimental halls of the salt mine under Lake Erie in Ohio converted to a proton decay detector designed by Sulak and the rest of the Irvine Michigan Brookhaven collaboration. The 1996 update of the book has replaced this description with another physicist led tour of another Sulak experimental collaboration effort on the muon g-2 measurement at Brookhaven National Laboratory.

Much has been learned about histone H1 from studies on purified chromatin fibers. Ionic extraction of linker histones from native or reconstituted chromatin promotes its unfolding under hypotonic conditions from fibers of 30 nm width to beads-on-a-string nucleosome arrays. It is uncertain whether H1 promotes a solenoid-like chromatin fiber, in which exposed linker DNA is shortened, or whether it merely promotes a change in the angle of adjacent nucleosomes, without affecting linker length However, linker histones have been demonstrated to drive the compaction of chromatin fibres that had been reconstituted in vitro using synthetic DNA arrays of the strong '601' nucleosome positioning element. Nuclease digestion and DNA footprinting experiments suggest that the globular domain of histone H1 localizes near the nucleosome dyad, where it protects approximately 15-30 base pairs of additional DNA.

A set-point or set point is a factory set or user programmable value for the desired partial pressure of oxygen in a rebreather loop. The feedback of actual oxygen partial pressure measured by the oxygen sensors is compared with the set-points, and if it deviates outside of the limits of upper and lower set-points, the control system will activate a solenoid valve to add oxygen or diluent gas to the loop to correct the oxygen content until it is within the set-point limits. Usually the user can override the gas addition by manual activation of injection valves. Some control systems allow depth activated switching of set-points, so that one pair of set-points can be selected for the main part of the dive, and another, usually richer, for accelerated decompression above the limiting depth.

The Alikhanian–Alikhanov spectrometer was a large solenoid physical instrument constructed by brothers Abraham Alikhanov and Artem Alikhanian at the Aragats scientific station in Armenia. The spectrometer was unique in the world.(in Russian) A. I. Alikhanian in the Gravitational field, by Gabriel Merzon, "7 iskusstv" Journal, #5, 2011 It had the highest amount of magnetic field (1,0x0,3x0,15 cubic meters) with the intensity up to 20 kGauss and was packed with four and five-layer proportional thin-walled counters of 4.6 mm diameter and 30–35 cm length, through which the coordinates of the trajectories of cosmic rays determined with an accuracy of about 1 mm. Spectrometer, that had a high resolution (maximum measurable pulse in the field of 20 kGauss was 150 GeV/c) was used to determine the momentum and mass of cosmic particles.

The final method, however, offers significant advantages since it achieves the final required field by repeated applications of a small field and can utilise a permanent magnet. If we wish to pulse a field using, say, a 10 T magnet to magnetize a 30 mm × 10 mm sample then we can work out how big the solenoid needs to be. If it were possible to wind an appropriate coil using YBCO tape then, assuming an Ic of 70 A and a thickness of 100 μm, we would have 100 turns and 7 000 A turns. This would produce a B field of approximately 7 000/(20 × 10−3) × 4π × 10−7 = 0.4 T. To produce 10 T would require pulsing to 1 400 A! An alternative calculation would be to assume a Jc of say 5 × 108Am−1 and a coil 1 cm2 in cross section.

Thomson passed his concepts on to Stan Cousins and Alan Ware, who assembled a linear pinch device using old radar equipment, and started operations in 1947. Follow-on experiments used large banks of capacitors to store energy that was quickly dumped into the plasma through a solenoid wrapped around a short tube. These experiments demonstrated a number of dynamic instabilities that caused the plasma to break up and hit the walls of the tube long before it was compressed or heated enough to reach the required fusion conditions. After a short time in Chicago, Tuck was hired by Los Alamos to work on the "Super" project (the hydrogen bomb), where he was put on the task of calculating the nuclear cross section of the deuterium-tritium fusion reaction. This work continued to pique his interest in fusion power, and he spent some time through 1951 considering the problem.

A survey of the sequenced genomes of complex prokaryotes from the PVC superphylum (Planctomycetes-Verrucomicrobia-Chlamydiae) identified examples of proteins with homology to eukaryotic membrane trafficking proteins, including examples of the distinctive beta- propeller/alpha-solenoid domain architecture previously believed to be unique to eukaryotes. The PVC superphylum is known for containing bacteria with unusually complex membrane morphology, and this discovery has been cited as evidence in favor of these organisms' status as an intermediate form between prokaryotes and eukaryotes. The planctomycete Gemmata obscuriglobus has exceptionally complex membrane architecture and has been a source of controversy in the literature regarding the possibility that it has a membrane-bound "nucleoid" compartment enclosing its DNA. The identification of proteins with sequence similarities to HEAT repeats in the G. obscuriglobus proteome has been interpreted as support for the membrane-bound nucleoid hypothesis; however, this has been disputed.

Mechanical snap action thermostat valve Electric snap Action thermostat with solenoid valve Snap action thermostats are the most common control used in heavy duty commercial griddles with medium-to-heavy production demands. These controls are called “snap action” because the control mechanism will turn the burner valve or electrical element fully on or completely off, with no modulation or intermediate heat source operation – effectively ‘snapping’ the heat source on or off. While not as responsive as solid state controls, snap action controls can maintain a griddle surface temperature within +/- 15 °F (8 °C) of set point if the thermostat bulb is embedded assuming a 1-inch (25mm) thick steel plate. This operating temperature range may be pushed to +/- 20 to 25 °F (10 °C to 13 °C) if the probe is bottom mounted due to the additional thermal hysteresis introduced by the plate material.

Fermilab's Illinois Accelerator Research Center (IARC) is a cutting-edge facility that unites scientists and engineers from Fermilab, Argonne, and Illinois universities with industrial partners Fermilab is a U.S hub for research into the Higgs boson and other high energy phenomena and is making major upgrades of the Compact Muon Solenoid (CMS) detector—one of two large detectors located at the Large Hadron Collider (LHC) at CERN in Europe. Fermilab is involved in cosmic research through the Dark Energy Survey, which includes over 120 scientists from 23 institutions in the United States, Spain, United Kingdom, Brazil, and Germany. The project relies on a Dark Energy camera, a high-resolution camera built at Fermilab for a telescope in Chile that will look for evidence of dark energy that is responsible for the expansion of the universe. In March 2015, a team of researchers using data collected during the first year of the survey discovered a rare dwarf satellite galaxy orbiting the Milky Way.

Della Negra studied mathematics and theoretical physics for his doctorate at the Laboratory of Nuclear Physics of the College de France in Paris, defending his thesis on the experimental study of proton-antiproton annihilation in 1967. In the 1970s, following post-doctoral work at the Stanford Linear Accelerator Center (SLAC) in Palo Alto, California, he involved himself on high-energy physics projects at CERN in Geneva, Switzerland, where he worked initially as a member of the Intersecting Storage Rings group. In 1977 joined the team led by Carlo Rubbia and played an important role in the 1981 discovery of the W and Z bosons. Della Nigra and his colleague from Imperial College London, Tejinder Singh Virdee, were among the first to envisage a hermetic detector for the large hadron collider (LHC) based on a strong magnetic field, the compact muon solenoid (CMS), and was spokesman for the CMS from 1992 until 2006.

The main upgrade activity on ALICE during LHC's Long Shutdown 1 was the installation of the dijet calorimeter (DCAL), an extension of the existing EMCAL system that adds 60° of azimuthal acceptance opposite the existing 120° of the EMCAL's acceptance. This new subdetector will be installed on the bottom of the solenoid magnet, which currently houses three modules of the photon spectrometer (PHOS). Moreover, an entirely new rail system and cradle will be installed to support the three PHOS modules and eight DCAL modules, which together weigh more than 100 tones. The installation of five modules of the TRD will follow and so complete this complex detector system, which consists of 18 units, In addition to these mainstream detector activities, all of the 18 ALICE subdetectors underwent major improvements during LS1 while the computers and discs of the online systems are replaced, followed by upgrades of the operating systems and online software.

Rain sensors for irrigation systems are available in both wireless and hard-wired versions, most employing hygroscopic disks that swell in the presence of rain and shrink back down again as they dry out — an electrical switch is in turn depressed or released by the hygroscopic disk stack, and the rate of drying is typically adjusted by controlling the ventilation reaching the stack. However, some electrical type sensors are also marketed that use tipping bucket or conductance type probes to measure rainfall. Wireless and wired versions both use similar mechanisms to temporarily suspend watering by the irrigation controller — specifically they are connected to the irrigation controller's sensor terminals, or are installed in series with the solenoid valve common circuit such that they prevent the opening of any valves when rain has been sensed. Some irrigation rain sensors also contain a freeze sensor to keep the system from operating in freezing temperatures, particularly where irrigation systems are still used over the winter.

Rarely, a final operating device such as a lamp or solenoid valve will be directly controlled by the contacts of an industrial limit switch, but more typically the limit switch will be wired through a control relay, a motor contactor control circuit, or as an input to a programmable logic controller. Miniature snap-action switch may be used for example as components of such devices as photocopiers, computer printers, convertible tops or microwave ovens to ensure internal components are in the correct position for operation and to prevent operation when access doors are opened. A set of adjustable limit switches are installed on a garage door opener to shut off the motor when the door has reached the fully raised or fully lowered position. A numerical control machine such as a lathe will have limit switches to identify maximum limits for machine parts or to provide a known reference point for incremental motions.

They are a corrugated flexible but strong sheet steel door, sliding up tracks and rolling around a drum mounted above the door opening on the inside of the garage. These come in manual and remote controlled electric (known as the Control-a-Door), with conversion kits available. Locking is provided by a key lock in the centre of the door moving two square sliding lock bars in and out of holes in the door tracks, locking and unlocking it, or by the solenoid lock in the automatic motor. Newer homes feature more American styled tilting panel lift doors which slide up onto a track on the ceiling via a motor and chain drive. Since the late 1970s most if not all garages are attached, and throughout the 80's it became more common to have an access door into the home from the garage where design permitted, whereas it is commonplace now.

Some drag race cars now use 16 volt DC systems, in such a scenario the delay box has to be capable of working properly from 16 volts DC, as well as 12 volts DC. The race car driver holds an electrical pushbutton switch depressed with a finger or a thumb of his right or left hand until he sees a specific desired visual cue. That electrical pushbutton switch is monitored by the delay box. As long as the race car driver holds the pushbutton depressed the delay box sends 12 Volts DC (or 16VDC) at many Amperes to the race car's transmission (where an internal electromagnetic solenoid located in or on the transmission energizes, which in turn positions a spool valve that directs hydraulic fluid pressure in the transmission valvebody that locks the transmission in forward and reverse gears at the same time). When the transbrake is engaged at the drag race track starting line (driver holding the pushbutton depressed), the car is held stationary regardless of how much engine power is applied to the drive line.

In the upper pool, the CESC Fountain of Joy will have 99 water effects, while the intermediate pool will have 20 water effects and another 30 special water effects in the lower pool. There will be a large water cascading area – more than 80 metre long from upper pool to the intermediate pool. The CESC Fountain of Joy comes with an enormous number of lights as also LED and PAR lamps, as also high watt reflectors, capable of constantly changing the colours to make the fountain attractive and eye- catching. According to CESC sources, the Fountain of Joy is integrated with ultra-fast technology, in which water effects will be controlled by the pneumatically assisted solenoid valves, capable of opening and shutting 12 times in a second, thereby resulting in water shooting in air at a spectacular speed. According to Mr. Sanjiv Goenka, “The inspiration for creating the new CESC Fountain of Joy in the Maidan comes from Chief Minister, Smt Mamata Banerjee, who is so keen to turn Kolkata into a beautiful megapolis.” The estimated cost is around Rs. 3 crore.

After an interval of 0.450 seconds, the start tank discharge valve was closed and a mainstage control solenoid was actuated to: #Turn off gas generator and thrust chamber helium purges #Open the gas generator control valve (hot gases from the gas generator now drive the pump turbines) #Open the main oxidizer valve to the first position (14 degrees) allowing LOX to flow to the LOX dome to burn with the fuel that has been circulating through the injector #Close the oxidizer turbine bypass valve (a portion of the gases for driving the oxidizer turbopump were bypassed during the ignition phase) #Gradually bleed the pressure from the closing side of the oxidizer valve pneumatic actuator controlling the slow opening of this valve for smooth transition into mainstage. Energy in the spark plugs was cut off and the engine was operating at rated thrust. During the initial phase of engine operation, the gaseous hydrogen start tank would be recharged in those engines having a restart requirement. The hydrogen tank was repressurized by tapping off a controlled mixture of LH2 from the thrust chamber fuel inlet manifold and warmer hydrogen from the thrust chamber fuel injection manifold just before entering the injector.

At Manchester he is engaged in experimental and theoretical research in the field of particle physics, with particular interest in the behaviours of particles in high energy colliders as at the ATLAS experiment and Compact Muon Solenoid (CMS) experiments, part of the Large Hadron Collider particle accelerator research at CERN in Geneva, Switzerland. He has said of his theoretical physics research, He has written over 100 peer-reviewed articles in scientific journals, including papers on ordering gluon emissions, quantum field theory and holographic wavefunction of mesons. Forshaw and his frequent co-author Cox have stated the peer review process of science results publishing is important because it ensures that minimum standards are met in the scientific community and gives due attribution to all associates working on the piece who are finalising the presentation of the paper, and blogging research before it is published should be avoided. QED: Question, Explore, Discover conference, 2017 As an educator Forshaw is keen to encourage the idea that basic principles and theories in particle physics should be introduced to children in school in order to encourage understanding of the scientific method and use of evidence-based thinking at a young age.

Developed in 1935 by Rheinmetall-Borsig as a commercial venture as the MG-101 (later designated MK 101, with the "MK" abbreviating the term Maschinenkanone, as an autocannon), the MK 101 cannon was a 30 mm (1.18 in), long-barreled automatic cannon capable of firing nine different types of 30x184B mm ammunition (ranging from basic high explosive to tungsten-cored armor-piercing rounds). Featuring pneumatic cocking and fired by percussion via an electrical solenoid, the MK 101 was recoil-operated. In operation, the barrel and bolt recoiled 30 mm (1.18 in) to the rear after each shot. The bolt locked via a Stange-type machined sleeve with internal interrupted threads, similar to some Solothurn weapons such as the 7.92 mm (.312 in) MG 30 light machine gun. The locking system was strong, but rate of fire was limited to a rather slow 230–260 rpm, which limited its use against other aircraft. Powerful and accurate for its day, it was carried primarily on the Henschel Hs 129 ground-attack aircraft, commencing in late 1941. Fed by a 10-round (early versions) or a 30-round box magazine, the MK 101 could penetrate 75 mm (3 in) of armor at 300 m (330 yd) range.

This included an updated XCJ-2 system from NRL (produced as the TX), the modified airborne AN/ARQ-8 Dinamate system from Harvard's Radio Research Laboratory, NRL's improved XCJ-3 model (produced as the CXGE), the Types MAS system produced by the Airborne Instruments Laboratory (at the time affiliated with the Radio Research laboratory), the British Type 651, and the Canadian Naval Jammer. Perhaps most impressive of all was AIL's Type MAS jammer, which employed sophisticated signals to defeat the Kehl transmission and to take over command of the Hs 293, steering it into the sea via a sequence of right- turn commands, triggering its solenoid-operated ailerons. Even more sophisticated jammers from NRL, designated XCK (to be produced as TY and designated TEA when combined with the upgraded XCJ-4) and XCL, were under development but were never deployed as the threat had evaporated before they could be put into service. In contrast to the experience at Anzio, jammers seemed to have had a major impact on operations after April 1944, with significant degradation observed in the probability that a Hs 293 launched at a target (and responding to operator guidance) would achieve a hit or damage- causing near miss.

The easiest spotting features of a PD-4103 over the rare PD-4102 are that the later model included a rear luggage bay door on the left side that did not appear on either the PD-4101 or PD-4102, as well as an improved refrigeration system, using the same Ingersoll-Rand rotary vane compressor as previous models, but with a larger evaporator coil using a better expansion valve and a larger supply fan located over the rear passengers' seats. To further improve air circulation and fresh air intake, exhaust fans were incorporated into the soffit at the head of each interior luggage rack, which operated from the same rheostat that controlled the main blower. Also included was a new, higher rated Delco generator and an improved voltage regulator, a redesigned reverse gear solenoid on the transmission, various evolutionary improvements to the 6-71 GM Diesel (tougher alloy exhaust valves and improved S-55 injectors as standard) and other miscellaneous minor improvements, including the addition of a "black light" instrument panel, in which the instruments had radium painted figures, very similar to what Ford introduced on their 1950 Ford passenger cars. Production of this bus totaled 1,501 with Greyhound Lines buying a substantial quantity.
