His invention uses what's known as a fractionating column, similar to the purification systems used in the petrochemical industry.

"Distillation happens in this first-of-its-kind-in-the-US continuous infinitely fractionating column still," Khosrovian said in front of his massive high-tech creation.

"It's the first of its type, period, and we're the first to have it in the US." So what does a continuous fractionating column still do?

Using existing sewage treatment and fractionating technologies, it is possible, in principle, to obtain safe, pure, nutritive compounds that could be recombined in new ways to meet all of our nutritional needs.

At Just, Hume was working with a team that was fractionating plants to look at their physical properties to identify what products could be made from the various proteins and chemicals researchers found in the plants.

In a lengthy email that I cannot fully do justice to in this column, Tooby wrote that everybody benefits from participating in groups of alliances and factions on different scales, and people also benefit by fractionating solidarity in such a way that those on the far side of the boundary seem undesirable, worth spurning, contemptible, deplorable.

Fractionating a communications satellite mission appears to be subject to , "Satellite cluster comprising a plurality of modular satellites".

The concept of effect sparsity is that not all factors will have an effect on the response. These principles are the foundation for fractionating Hadamard matrices. By fractionating, experimenters can form conclusions in fewer runs and with fewer resources. Oftentimes, RPDs are used at the early stages of an experiment.

Machine Sazi Arak (MSA) A fractionating column or fractional column is an essential item used in the distillation of liquid mixtures to separate the mixture into its component parts, or fractions, based on the differences in volatilities. Fractionating columns are used in small scale laboratory distillations as well as large scale industrial distillations.

A fraction in chemistry is a quantity collected from a batch of a substance in a fractionating separation process. In such a process, a mixture is separated into fractions, which have compositions that vary according to a gradient. A fraction can be defined as a group of chemicals that have similar boiling points. A common fractionating process is fractional distillation.

This variation is uncontrollable and affects the consumers opinion of the product; therefore, the manufacturer wants the product to be robust to variations due to temperature. To run every possible combination of factors would be 128 runs. However, by fractionating this matrix, the effects of factors can be seen in much fewer runs. Therefore, fractionating is less costly and less time consuming.

In the simplest case, there are just one feed stream and two product streams. In the case of fractionating column there are instead many product streams.

Typical laboratory fractional distillation unit For many cases, the boiling points of the components in the mixture will be sufficiently close that Raoult's law must be taken into consideration. Therefore, fractional distillation must be used in order to separate the components by repeated vaporization-condensation cycles within a packed fractionating column. This separation, by successive distillations, is also referred to as rectification. As the solution to be purified is heated, its vapors rise to the fractionating column.

Figure 1: Fractional distillation apparatus using a Liebig condenser. Vigreux column in a laboratory setup A laboratory fractionating column is a piece of glassware used to separate vaporized mixtures of liquid compounds with close volatility. Most commonly used is either a Vigreux column or a straight column packed with glass beads or metal pieces such as Raschig rings. Fractionating columns help to separate the mixture by allowing the mixed vapors to cool, condense, and vaporize again in accordance with Raoult's law.

Bubble-cap "trays" or "plates" are one of the types of physical devices, which are used to provide good contact between the upflowing vapor and the downflowing liquid inside an industrial fractionating column. Such trays are shown in Figures 4 and 5. The efficiency of a tray or plate is typically lower than that of a theoretical 100% efficient equilibrium stage. Hence, a fractionating column almost always needs more actual, physical plates than the required number of theoretical vapor–liquid equilibrium stages.

Sometimes, colonies proliferate by "budding" (also called "satelliting" or "fractionating"), where a subset of the colony including queens, workers and brood (eggs, larvae and pupae) leave the main colony for an alternative nest site.

Sometimes, colonies proliferate by "budding" (also called "satelliting" or "fractionating") whereby a subset of the colony, including queens, workers and brood (eggs, larvae and pupae) leave the main colony for an alternative nest site.

The "lightest" products with the lowest boiling points exit from the top of the columns and the "heaviest" products with the highest boiling points exit from the bottom. Industrial fractionating columns use external reflux to achieve better separation of products. Reflux refers to the portion of the condensed overhead liquid product that returns to the upper part of the fractionating column as shown in Figure 3. Inside the column, the downflowing reflux liquid provides cooling and condensation of upflowing vapors thereby increasing the efficacy of the distillation tower.

Fritz Nebel (1891–1977)Friedrich L. Bauer: Decrypted Secrets, Methods and Maxims of Cryptology. Springer, Berlin 2007 (4. Aufl.), S. 53, . and introduced in March 1918, the cipher was a fractionating transposition cipher which combined a modified Polybius square with a single columnar transposition.

The amount of heat entering the column from the reboiler and with the feed must equal the amount heat removed by the overhead condenser and with the products. The heat entering a distillation column is a crucial operating parameter, addition of excess or insufficient heat to the column can lead to foaming, weeping, entrainment, or flooding. Figure 3 depicts an industrial fractionating column separating a feed stream into one distillate fraction and one bottoms fraction. However, many industrial fractionating columns have outlets at intervals up the column so that multiple products having different boiling ranges may be withdrawn from a column distilling a multi-component feed stream.

Laboratory apparatus using reflux to supply energy to chemical reactions. An Erlenmeyer flask is used as a receiving flask. Here the distillation head and fractionating column are combined in one piece. The apparatus shown in the diagram represents a batch distillation as opposed to a continuous distillation.

This polymerisation is undesirable, as it can foul the fractionating tower, it is also typically exothermic which can lead to a runaway reaction and potential explosion if left unchecked. Once initiated polymerisation is typically radical in mechanism and as such many polymerisation inhibitors act as radical scavengers.

In a typical chemical plant, it accounts for about 40% of the total energy consumption. Industrial distillation is typically performed in large, vertical cylindrical columns (as shown in Figure 2) known as "distillation towers" or "distillation columns" with diameters ranging from about 65 centimeters to 6 meters and heights ranging from about 6 meters to 60 meters or more. Figure 3: Chemical engineering schematic of a continuous fractionating column Figure 4: Chemical engineering schematic of typical bubble-cap trays in a fractionating column Industrial distillation towers are usually operated at a continuous steady state. Unless disturbed by changes in feed, heat, ambient temperature, or condensing, the amount of feed being added normally equals the amount of product being removed.

Compounds with a boiling point lower than 150 °C can typically be distilled at ambient pressure. A fractionating column allow separation of compounds with similar boiling points. A variety of apparatus is commercially available. In addition to the distillation apparatus, a vacuum pump, heat source, and a vacuum gauge are required.

It is used to produce liquor and various hydrocarbon fuels, such as gasoline, kerosene and diesel. A fraction is the product of a fractionating column, a vast chamber designed to separate different substances (such as crude oil) based on their boiling point. Fraction could also refer to a description of the composition of a mixture, e.g. mass fraction or mole fraction.

Nepal Distilleries Private Limited started producing Khukri Rum in 1959 in Kathmandu, Nepal. Initially the company started distilling alcohol from pot stills. Those initial pot stills are on display in its factory premises and the company now uses three fractionating columns for distillation of alcohol. Distilled from fermented molasses, the Khukri Rum is aged for a minimum of eight months in wooden vats.

Industrially, NaK is produced in a reactive distillation. In this continuous process, a distillation column is fed with potassium chloride and sodium. In the reaction zone, potassium chloride reacts with sodium to form sodium chloride and potassium. The lighter-boiling potassium is enriched in an upper fractionating zone and drawn at the column head while molten sodium chloride is withdrawn from the bottom.

Later, once computerized control came about (for example, CNC), jigs were obviated, but it remained true that the skill (or knowledge) was built into the tool (or process, or documentation) rather than residing in the worker's head. This is the specialized capital required for mass production; each workbench and set of tools (or each CNC cell, or each fractionating column) is different (fine- tuned to its task).

Second, it said, the claimed method did not "'transform' the claimed naturally occurring phenomenon into a patent-eligible application"of the phenomenon. The court reasoned that, "[f]or process claims that encompass natural phenomen[a], the process steps . . . must be new and useful." But researchers already knew how to accomplish the individual steps of (1) fractionating blood; (2) amplifying DNA; and (3) detecting characteristics in amplified DNA.

With each condensation-vaporization cycle, the vapors are enriched in a certain component. A larger surface area allows more cycles, improving separation. This is the rationale for a Vigreux column or a packed fractionating column. Spinning band distillation achieves the same outcome by using a rotating band within the column to force the rising vapors and descending condensate into close contact, achieving equilibrium more quickly.

Spinning band distillation is a technique used to separate liquid mixtures which are similar in boiling points. When liquids with similar boiling points are distilled, the vapors are mixtures, and not pure compounds. Fractionating columns help separate the mixture by allowing the mixed vapors to cool, condense, and vaporize again in accordance with Raoult's law. With each condensation-vaporization cycles, the vapors are enriched in a certain component.

The operation became the only commercial whey fractionating plant in the United States to use chromatography methods. The addition of an automated cheddaring system later in 1998 increased plant capacity. As the company grew and the need for sales and marketing resources increased, Davisco Foods International moved its original Le Sueur sales headquarters to Eden Prairie, Minnesota. The company later added sales offices in Mexico City, Mexico, and Geneva, Switzerland.

Cumulate rocks are the typical product of precipitation of solid crystals from a fractionating magma chamber. These accumulations typically occur on the floor of the magma chamber, although they are possible on the roofs if anorthite plagioclase is able to float free of a denser mafic melt. Cumulates are typically found in ultramafic intrusions, in the base of large ultramafic lava tubes in komatiite and magnesium rich basalt flows and also in some granitic intrusions.

Fractional Distillation. fandm.edu In reality, each cycle at a given temperature does not occur at exactly the same position in the fractionating column; theoretical plate is thus a concept rather than an accurate description. More theoretical plates lead to better separations. A spinning band distillation system uses a spinning band of Teflon or metal to force the rising vapors into close contact with the descending condensate, increasing the number of theoretical plates.

The naphtha cut, as that fraction is called, contains many different hydrocarbon compounds. Therefore, it has an initial boiling point of about 35 °C and a final boiling point of about 200 °C. Each cut produced in the fractionating columns has a different boiling range. At some distance below the overhead, the next cut is withdrawn from the side of the column and it is usually the jet fuel cut, also known as a kerosene cut.

If two factors interact, then the effect one factor has on the response is different depending on the settings of another factor. Fractionating Hadamard matrices appropriately is very time-consuming. Consider a 24-run design accommodating six factors. The number of Hadamard designs from each Hadamard matrix is 23 choose 6; that is 100,947 designs from each 24×24 Hadamard matrix. Since there are 60 Hadamard matrices of that size, the total number of designs to compare is 6,056,820.

Each colony produces sexually reproductive individuals roughly twice a year. However, colonies raised in a laboratory can be manipulated to produce sexuals at any time of year. Colonies proliferate by "budding"Pharaoh Ant Elimination (also called "satelliting" or "fractionating"), where a subset of the colony including queens, workers and brood (eggs, larvae and pupae) leave the main colony for an alternative nest site. Pharaoh ant colonies appear to prefer familiar nests to novel nests while budding.

The next step depends on the methodology of individual laboratories. Bioassay-guided fractionation is a common method to find biologically active compounds. This involves testing the crude extract or preliminary fractions from chromatography in an assay or multiple assays, determining what fractions or crude extracts show activity in the specific assays, and further fractionating the active fractions or extracts. This step is than repeated where the new fractions are tested and the active fractions are further fractionated.

In practice when there are multiple distillate fractions, the distillate exit points are located at different heights on a fractionating column. The bottoms fraction can be taken from the bottom of the distillation column or unit, but is often taken from a reboiler connected to the bottom of the column. Each fraction may contain one or more components (types of chemical compounds). When distilling crude oil or a similar feedstock, each fraction contains many components of similar volatility and other properties.

A pot still incorporates only one condensation, whereas other types of distillation equipment have multiple stages which result in higher purification of the more volatile component (alcohol). Pot still distillation gives an incomplete separation, but this can be desirable for the flavor of some distilled beverages. If a purer distillate is desired, a reflux still is the most common solution. Reflux stills incorporate a fractionating column, commonly created by filling copper vessels with glass beads to maximize available surface area.

In a typical fractional distillation, a liquid mixture is heated in the distilling flask, and the resulting vapor rises up the fractionating column (see Figure 1). The vapor condenses on glass spurs (known as trays or plates) inside the column, and returns to the distilling flask, refluxing the rising distillate vapor. The hottest tray is at the bottom of the column and the coolest tray is at the top. At steady-state conditions, the vapor and liquid on each tray reach an equilibrium.

The more reflux and/or more trays provided, the better is the tower's separation of lower boiling materials from higher boiling materials. The design and operation of a fractionating column depends on the composition of the feed and as well as the composition of the desired products. Given a simple, binary component feed, analytical methods such as the McCabe–Thiele method or the Fenske equation can be used. For a multi- component feed, simulation models are used both for design, operation, and construction.

The first column (called the analyzer) in a column still has steam rising and wash descending through several levels. The second column (called the rectifier) carries the alcohol from the wash, where it circulates until it can condense at the required strength. A column still is an example of a fractional distillation, in that it yields a narrow fraction of the distillable components. This technique is frequently employed in chemical synthesis; in this case, the component of the still responsible for the separation is a fractionating column.

And still later, access to Japanese Army messages from decrypts of Army communications traffic assisted in planning the island hopping campaign to the Philippines and beyond. Another source of information was the Japanese Military Attaché code (known as JMA to the Allies) introduced in 1941. This was a fractionating transposition system based on two-letter code groups which stood for common words and phrases. The groups were written in a square grid according to an irregular pattern and read off vertically, similar to a disrupted columnar transposition.

The Polybius square, also known as the Polybius checkerboard, is a device invented by the ancient Greeks Cleoxenus and Democleitus, and made famous by the historian and scholar Polybius. The device is used for fractionating plaintext characters so that they can be represented by a smaller set of symbols, which is useful for telegraphy steganography, and cryptography. The device was originally used for fire signalling, allowing for the coded transmission of any message, not just a finite amount of predetermined options as was the convention before.

Isotopic reference materials are compounds (solids, liquids, gasses) with well-defined isotopic compositions and are the ultimate sources of accuracy in mass spectrometric measurements of isotope ratios. Isotopic references are used because mass spectrometers are highly fractionating. As a result, the isotopic ratio that the instrument measures can be very different from that in the sample's measurement. Moreover, the degree of instrument fractionation changes during measurement, often on a timescale shorter than the measurement's duration, and can depend on the characteristics of the sample itself.

All three minerals preferentially fractionate Y, yet they form and break down at different stages of metamorphism. Xenotime has the highest fractionating power, then garnet and then monazite. In a simplified case of a clockwise P-T path involving garnet and monazite, garnet grows along a prograde path with Y continuously being incorporated, thus the Y content in monazite formed at this stage (prograde) should decrease progressively with higher grade. However, as temperature increases to a certain point, partial melting (anatectic) of monazite occurs around its rim, releasing Y into the melts.

The liquid feed mixture to be distilled is placed into the round-bottomed flask along with a few anti-bumping granules, and the fractionating column is fitted into the top. As the mixture is heated and boils, vapor rises up the column. The vapor condenses on the glass platforms (known as plates or trays) inside the column and runs back down into the liquid below, thereby refluxing the upflowing distillate vapor. The hottest tray is at the bottom of the column and the coolest tray is at the top.

So-called bubble-cap or valve-cap trays are examples of the vapor and liquid contact devices used in industrial distillation columns. Another example of vapor and liquid contact devices are the spikes in laboratory Vigreux fractionating columns. The trays or plates used in industrial distillation columns are fabricated of circular steel plates and usually installed inside the column at intervals of about 60 to 75 cm (24 to 30 inches) up the height of the column. That spacing is chosen primarily for ease of installation and ease of access for future repair or maintenance.

A common refining scheme consists in fractionating the reformate in two streams, light and heavy reformate. The light reformate has lower octane and can be used as isomerization feedstock if this unit is available. The heavy reformate is high in octane and low in benzene, hence it is an excellent blending component for the gasoline pool. Benzene is often removed with a specific operation to reduce the content of benzene in the reformate as the finished gasoline has often an upper limit of benzene content (in the UE this is 1% volume).

Huttonite was first described in 1950 from beach sand and fluvio-glacial deposits in South Westland, New Zealand, where it was found as anhedral grains of no more than 0.2 mm maximum dimension. It is most prevalent in the sand at Gillespie's Beach, near Fox Glacier, which is the type location, where it is accompanied by scheelite, cassiterite, zircon, uranothorite, ilmenite and gold. It was found at a further six nearby locations in less plentiful amounts. Huttonite was extracted from the sands by first fractionating in iodomethane and then electromagnetically.

Chemical engineers must choose what combination of reflux rate and number of plates is both economically and physically feasible for the products purified in the distillation column. Such industrial fractionating towers are also used in cryogenic air separation, producing liquid oxygen, liquid nitrogen, and high purity argon. Distillation of chlorosilanes also enables the production of high-purity silicon for use as a semiconductor. Section of an industrial distillation tower showing detail of trays with bubble caps Design and operation of a distillation tower depends on the feed and desired products.

In this example, a mixture of 96% ethanol and 4% water boils at ; the mixture is more volatile than pure ethanol. For this reason, ethanol cannot be completely purified by direct fractional distillation of ethanol-water mixtures. The apparatus is assembled as in the diagram. (The diagram represents a batch apparatus as opposed to a continuous apparatus.) The mixture is put into the round bottomed flask along with a few anti-bumping granules (or a Teflon coated magnetic stirrer bar if using magnetic stirring), and the fractionating column is fitted into the top.

JN-39 was replaced by JN-40, which was originally believed to be a code super-enciphered with a numerical additive in the same way as JN-25. However, in September 1942, an error by the Japanese gave clues to John MacInnes and Brian Townend, codebreakers at the British FECB, Kilindini. It was a fractionating transposition cipher based on a substitution table of 100 groups of two figures each followed by a columnar transposition. By November 1942, they were able to read all previous traffic and break each message as they received it.

Certain isotopes of trace metals are preferentially oxidized or reduced; thus, transitions between redox species of the metal ions (e.g., Fe2+ → Fe3+) are fractionating, resulting in different isotopic compositions between the different redox pools in the environment. Additionally, at high temperatures, metals ions can evaporate (and subsequently condense upon cooling), and the relative differences in isotope masses of a given heavy metal leads to fractionation during these evaporation and condensation processes. Diffusion of isotopes through a solution or material can also result in fractionations, as the lighter mass isotopes are able to diffuse at a faster rate.

This process is called budding, also called "satelliting" or "fractionating", where a subset of the colony leave the main colony for an alternative nest site. This may not be the case entirely, as some queens can establish their own colonies. Inseminated queens can successfully establish a colony in non-claustral, haplometrotic conditions (as in founded by a single queen that hunts for food to feed her young), but the development of a colony straight after colony founding is very slow, whereas other Rhytidoponera species tend to grow faster. There is also a clear sign of division of labour between the queens and workers.

In 2018, Graanul Invest announced that it will build in cooperation with the American biotech company Sweetwater Energy a wood fractionation plant to produce different sugars and lignin by using the Sunburst fractionating technology. In October 2018, Graanul Invest sold 10 pellet-fueled boiler houses to Adven Eesti. In 2018, Granul Invest bought the bulk carrier M/V Nord Shanghai (now: M/V Imavere) from the Danish shipping company D/S Norden, and in 2019 the bulk carrier M/V Nord Mumbai . In 2019, Graanul Invest re-entered into the United States market by acquiring Texas Pellets' assets from insolvent German Pellets.

After he spilled some potassium permanganate solution on his bedroom carpet his mother confined him to an alcove in the garage which he turned into a small laboratory, replete with industrial chemicals and second-hand laboratory glassware. Gunther was interested in finding out how things like detergents and oils were composed by cracking them in his fractionating column. He took particular interest in mixing paints for his art classes, as well as his chemistry classes in Balwyn High School. His father, being the Superintendent of Melbourne's electrical power station, borrowed an organic chemistry text from the chemists in the quality control laboratory.

In gas chromatography, the mobile phase (or "moving phase") is a carrier gas, usually an inert gas such as helium or an unreactive gas such as nitrogen. Helium remains the most commonly used carrier gas in about 90% of instruments although hydrogen is preferred for improved separations. The stationary phase is a microscopic layer of liquid or polymer on an inert solid support, inside a piece of glass or metal tubing called a column (an homage to the fractionating column used in distillation). The instrument used to perform gas chromatography is called a gas chromatograph (or "aerograph", "gas separator").

A balance of heating with a reboiler at the bottom of a column and cooling by condensed reflux at the top of the column maintains a temperature gradient (or gradual temperature difference) along the height of the column to provide good conditions for fractionating the feed mixture. Reflux flows at the middle of the tower are called pumparounds. Changing the reflux (in combination with changes in feed and product withdrawal) can also be used to improve the separation properties of a continuous distillation column while in operation (in contrast to adding plates or trays, or changing the packing, which would, at a minimum, require quite significant downtime).

Fractional distillation is one of the unit operations of chemical engineering. Fractionating columns are widely used in the chemical process industries where large quantities of liquids have to be distilled. Such industries are the petroleum processing, petrochemical production, natural gas processing, coal tar processing, brewing, liquified air separation, and hydrocarbon solvents production and similar industries but it finds its widest application in petroleum refineries. In such refineries, the crude oil feedstock is a complex, multicomponent mixture that must be separated, and yields of pure chemical compounds are not expected, only groups of compounds within a relatively small range of boiling points, also called fractions.

Figure 5: Section of fractionating tower of Figure 4 showing detail of a pair of trays with bubble caps Figure 6: Entire view of a Distillation Column In industrial uses, sometimes a packing material is used in the column instead of trays, especially when low pressure drops across the column are required, as when operating under vacuum. This packing material can either be random dumped packing ( wide) such as Raschig rings or structured sheet metal. Liquids tend to wet the surface of the packing, and the vapors pass across this wetted surface, where mass transfer takes place. Differently shaped packings have different surface areas and void space between packings.

Chemical engineers design, construct and operate process plants (fractionating columns pictured). Chemical engineering is a branch of engineering that uses principles of chemistry, physics, mathematics, biology, and economics to efficiently use, produce, design, transport and transform energy and materials. The work of chemical engineers can range from the utilization of nanotechnology and nanomaterials in the laboratory to large-scale industrial processes that convert chemicals, raw materials, living cells, microorganisms, and energy into useful forms and products. Chemical engineers are involved in many aspects of plant design and operation, including safety and hazard assessments, process design and analysis, modeling, control engineering, chemical reaction engineering, nuclear engineering, biological engineering, construction specification, and operating instructions.

In industrial continuous fractionating columns, is determined by starting at either the top or bottom of the column and calculating material balances, heat balances and equilibrium flash vaporizations for each of the succession of equilibrium stages until the desired end product composition is achieved. The calculation process requires the availability of a great deal of vapor–liquid equilibrium data for the components present in the distillation feed, and the calculation procedure is very complex. In an industrial distillation column, the required to achieve a given separation also depends upon the amount of reflux used. Using more reflux decreases the number of plates required and using less reflux increases the number of plates required.

Copurification in a chemical or biochemical context is the physical separation by chromatography or other purification technique of two or more substances of interest from other contaminating substances. For substances to co-purify usually implies that these substances attract each other to form a non- covalent complex such as in a protein complex. However, when fractionating mixtures, especially mixtures containing large numbers of components (for example a cell lysate), it is possible by chance that some components may copurify even though they don't form complexes. In this context the term copurification is sometimes used to denote when two biochemical activities or some other property are isolated together after purification but it is not certain if the sample has been purified to homogeneity (i.e.

The distribution of grilles, an example of the difficult problem of key exchange, can be eased by taking a readily-available third- party grid in the form of a newspaper crossword puzzle. Although this is not strictly a grille cipher, it resembles the chessboard with the black squares shifted and it can be used in the Cardan manner. The message text can be written horizontally in the white squares and the ciphertext taken off vertically, or vice versa.

Typical vapor–liquid separator The Souders–Brown equation (named after Mott Souders and George Granger BrownAnalytical Study of Liquid/Vapour Separation Efficiency , study developed by W.D. Monnery, Chem-Pet Process Technology Ltd. and W.Y. Svrcek, University of Calgary, Calgary, Canada, 2005, for Petroleum Technology Alliance Canada) has been a tool for obtaining the maximum allowable vapor velocity in vapor–liquid separation vessels (variously called flash drums, knockout drums, knockout pots, compressor suction drums and compressor inlet drums). It has also been used for the same purpose in designing trayed fractionating columns, trayed absorption columns and other vapor–liquid-contacting columns. A vapor–liquid separator drum is a vertical vessel into which a liquid and vapor mixture (or a flashing liquid) is fed and wherein the liquid is separated by gravity, falls to the bottom of the vessel, and is withdrawn.

He observed that Fleissner's method could be applied to a fractionating cipher, such as a Delastelle Bifid or Four-Square, with considerable increase in security. Grille ciphers are also useful device for transposing Chinese characters; they avoid the transcription of words into alphabetic or syllabic characters to which other ciphers (for example, substitution ciphers) can be applied. After World War I, machine encryption made simple cipher devices obsolete, and grille ciphers fell into disuse except for amateur purposes.

Since the canal, the waters of the lower Metedeconk have been brackish to salty and the ecology of the area has changed considerably. A visual indication of the river's connection to the ocean is the cream to brown colored foam that sometimes collects where the Metedeconk's waves beat the sandy shores or manmade bulkheads. This foam consists of the microscopic organic material that naturally builds up in the presence of aquatic life; the process of filtering organics from water through wave-like action has been mechanized in most aquariums and is known there as foam fractionating. As of October 29, 2012, due to the effects of Hurricane Sandy hitting New Jersey, an inlet opened between Barnegat Bay and the Atlantic Ocean at the river's east end, the storm having obliterated the dunes, roads, and houses that once blocked off the river from the ocean.

Control of fractionating columns is one of the more challenging applicationsAutomatic control systems were first developed over two thousand years ago. The first feedback control device on record is thought to be the ancient Ktesibios's water clock in Alexandria, Egypt around the third century B.C.E. It kept time by regulating the water level in a vessel and, therefore, the water flow from that vessel. This certainly was a successful device as water clocks of similar design were still being made in Baghdad when the Mongols captured the city in 1258 A.D. A variety of automatic devices have been used over the centuries to accomplish useful tasks or simply just to entertain. The latter includes the automata, popular in Europe in the 17th and 18th centuries, featuring dancing figures that would repeat the same task over and over again; these automata are examples of open-loop control.

Within the basket- resembling, for individual head circumference adjustable plastic holder of the helmet rests the earth, similar to a breakfast egg in an egg cup. On the Earth, apart from the northern part of the African continent, Europe and the Arctic, an industrial plant is perceivable as an independent continent, consisting of fractionating columns, spherical gas tanks, pipelines and a gas flare stack. It seems as though the observer would cast a future glance into the crystal ball of a clairvoyant, whereas this future reveals itself as a growing, globally expanding industrial world. The angle measurement of 359° preceding the book title Workadays Life Of An Industrial Gypsy is meant to express that no man-made workmanship will ever achieve perfection (the geometric unit of a turn). The subheadingYou’ll Never Work Alone is borrowed in slightly altered form from the song text You'll Never Walk Alone.

The hot reaction products from the third reactor are partially cooled by flowing through the heat exchanger where the feed to the first reactor is preheated and then flow through a water- cooled heat exchanger before flowing through the pressure controller (PC) into the gas separator. Most of the hydrogen-rich gas from the gas separator vessel returns to the suction of the recycle hydrogen gas compressor and the net production of hydrogen-rich gas from the reforming reactions is exported for use in the other refinery processes that consume hydrogen (such as hydrodesulfurization units and/or a hydrocracker unit). The liquid from the gas separator vessel is routed into a fractionating column commonly called a stabilizer. The overhead offgas product from the stabilizer contains the byproduct methane, ethane, propane and butane gases produced by the hydrocracking reactions as explained in the above discussion of the reaction chemistry of a catalytic reformer, and it may also contain some small amount of hydrogen.
