Title: Manufacture of hydrocarbons
IPC: C07C1/04
Filed: 1946-09-12
Abstract: Liquid hydrocarbons are produced by contacting a synthesis gas composed of 40-60 per cent CO, 50-30 per cent H2, and minor amounts of other gases under a pressure of 10-50 atmos. with an iron catalyst at 300-350 DEG  C., catalytically reacting part of the residual gas with methane at 800-1000 DEG  C. to yield carbon monoxide, hydrogen, and a little methane, reacting another part of the residual gas with coke at above 1000 DEG  C. to yield carbon monoxide with a little hydrogen and methane, and blending the two gaseous products to give the synthesis gas.  Methane mixed with a small amount of steam is preheated, mixed with preheated residue gas from the carbon monoxide hydrogenation reaction, composed mainly of carbon dioxide, and passed over alundum or corundum impregnated with nickel, at 800-1000 DEG  C. to give a product which is 40-50 per cent CO, 40-65 per cent H2 and 2-10 per cent CH4.  The remainder of the residue gas is reacted with coke in a producer which is first brought to 1200-1800 DEG  C. by a hot air blast.  The carbon monoxide formed is cooled, scrubbed with water and potassium carbonate, purified with iron oxide and soda ash, and mixed with the gas from methane conversion.  The mixed gases pass through a sintered iron catalyst with ThO2, CaO, Cu or other activator, liquid products being condensed and residual gases recycled as described.

Filed: 1954-09-24
Abstract: 761,630. Jigging conveyers. GEWERKSCHAFT EISENHUTTE WESTFALIA. Sept. 24, 1954 [Dec. 11, 1953], No. 27686/54. Class 78(1). In reciprocatory shovel loaders a which are driven under the iron minerals while being vibrated at a relatively high frequency, e.g. 180 to 1500 per minute, but with a relatively small amplitude, e.g. 5 to 100 mm., and which deliver the minerals to a scraper or belt conveyer l which feeds them to another conveyer or to a series of trucks, the conveyer l is supported by the shovel system by means which are so arranged that the vibrations of the shovel either are not transmitted to the conveyer or are transmitted only to a reduced extent. The shovel is mounted between bars b which are connected by cross-members c. The oscillations of the shovel are produced by a compressed air motor d which is mounted between the members c. Brackets p fixed to the bars b support pivoted rods q, the lower ends of which are pivoted to brackets r mounted below the conveyer frame. The frame is supported also by a roller o placed between curved tracks m, n on the bars and conveyer frame, respectively. The piston-rod of a compressed air cylinder f mounted on the bars b bears against a rail clamp g which is actuated by a lever h. When air is admitted to the cylinder, the pressure exerted by the piston-rod on the clamp, forces the shovel under the minerals. A rubber apron t bridges the gap between tie s hovel and conveyer.

Title: Manufacture of alkali-ethylates
IPC: C07C29/70
Filed: 1929-09-12
Abstract: 334,388. Wacker Ges. f³r Elektrochemische Industrie, Ges., Dr. A. Nov. 24, 1928, [Convention date]. Alkali-ethylcates.-Alkali hydroxide and alcohol are caused to react at a temperature above the boiling point of alcohol. The higher temperature may be obtained by the application of pressure or by the addition of a high-boiling liquid such as paraffin, and the water formed in the reaction is removed in aqueous alcohol by distillation. An auxiliary liquid such as benzene or its homologues, or hydrocarbons such as hexane which are capable of forming azeotropic mixtures with water, alcohol or both, may be present. In an example powdered caustic soda is suspended in paraffin oil of high boiling point heated to 200‹ C., and alcohol vapour is passed in at the same temperature. The distillate contains 2.5 per cent of water. In another example, a solution of caustic soda in anhydrous alcohol is distilled under a pressure of 10 atmospheres, giving a distillate containing 1.75 per cent of water. An example is also given in which caustic soda is mixed with alcohol and benzene and distilled under a nressure of 7 atmospheres using a column and dephlegmator until 99 per cent of the water of reaction has been removed; 370 calories are required for each gram-molecule of caustic soda used, whereas 1100 calories are required for a corresponding reaction under normal pressure. Caustic potash may be used in place of caustic soda.

Title: Improved method of feeding fuel into internal combustion or explosion engines
IPC: F02B1/00
Filed: 1922-10-16
Abstract: 208,294. Bouffart, M. Oct. 16, 1922. Two-stroke-cycle engines.-Engines are supplied with preliminary compressed combustible mixture, which is composed in the exact proportions in which it is to be exploded or burnt in the combustion chamber without being subjected therein to any additional treatment such as compression or addition of air, said mixture being stored in a tank of large capacity so as not to be scavenged or agitated during working of the engine. A vehicle engine working according to the invention, would compose for example a ca-burettor for producing the mixture, and a compressor for forcing the mixture into a tank. The arrangement allows the carburettor and compressor to function intermittently and not cycle by cycle as is known. The said devices may therefore be in use when power is available. The invention is particularly applicable to vehicle and aeronautical engines, and enables temporary overloads to be met.

Abstract: 447,042. Rotary pumps. BRITISH CELANESE, Ltd., 22, Hanover Square, London, and KINSELLA, E., c/o British Celanese, Ltd., Spondon, near Derby. Oct. 3, 1934, No. 28294. [Class 110 (ii)] [See also Groups XXIX and XXVIII] A sensitive device for maintaining constant the output of a pump comprises a hollow piston valve operated by a sheet metal bellows the inside of which is connected to the inlet of the pump and the space outside the bellows to the outlet of the pump, so that the bellows operates to neutralize any change in the relative pressure between these points. The apparatus is specially intended to deal with spinning solution in the manufacture of artificial silk. The device shown in Fig. 2 may be used in the apparatus described in Specification 293,325, [Class 110 (ii)], in which a single pump 13 is used having gears 31. Liquid entering by a pipe 11 flows by way of a passage 23, groove 24, triangular hole 27 in a piston valve 16, slot 28, groove 25, and passage 29 to the pump intake. The outlet passages 33, 34, 35 are connected as shown to a third groove 26 and a chamber 17 containing the bellows 18. If the pressure in the chamber rises above that in the pump inlet the bellows collapses and raises the valve. This increases the effective aperture at 27 and therefore the inlet pressure until equality is reached. If the contrary happens and the bellows expands the valve falls and the supply to the pump falls off. If the rise of pressure in the chamber is excessive, on further rise of the valve a shoulder 36 uncovers the groove 26 and the pump is byepassed through the interior of the valve and apertures 22. If the pressure falls abnormally, the aperture 27 is closed and the flow ceases. When two pumps 56, 65, Fig. 5, in series are employed, as described in Specification 182,154, [Class 110 (ii)], the first, 56, is provided with a byepass controlled by a valve operated by a bellows sensitive to the pressures on the inlet and outlet sides of the second pump 65. If the pressure rises in the outlet chamber 48 the bellows 49 will raise the valve 47 so that the effective area of an angular aperture 62 is reduced, whereupon the byepass formed by the passages 58, 61, interior of bellows, holes 53, interior of valve, and aperture 62, is throttled, until the pressures in the chamber 48 and outlet 58 of the first pump 56 are equal. If the rise is excessive the shoulder 72 of the valve uncovers the groove 59 and opens the byepass so that no liquid reaches the second pump and flow at the outlet 4 ceases. At the same time the aperture 62 is raised to register with a groove 60 in communication with the outlet 67 of the pump 65 and thus byepass this pump. If the pressure in the outlet falls the valve 47 falls until the groove 60 is uncovered so that the insides of the bellows and the inlet 64 communicate with the chamber 48 and the outlet 66 ; at the same time the aperture 62 byepasses the first pump. A compound form of bellows, Fig. 8, may be used if a larger range of motion is desired.
