Abstract: 1371953 Coat polyvinyl chloride articles AJINOMOTO CO Inc 10 May 1972 [11 May 1971], 21958/72 Heading B1E The surface of a plasticised polyvinyl chloride article is primed with a coating of a solution in an organic solvent of a polyurethane elastomer having cyclohexyl radicals in the polyurethane molecules, and then topcoated with a resin composition comprising a poly-α-amino acid. In Examples the product is simulated leather. The substrate may be prepared from granular or other rsin compositions by calendering, moulding or extrusion, may be p.v.c. impregnated fabric and may be foamed. The polyurethane elastomer is made by first making a.prepolymer by reacting a diisocyanate compound having a cyclohexyl radical with a macromolecular compound (such as a polyester, polyether, polyamide or polyolefin) having terminal functional groups containing active hydrogen (such as hydroxyl, primary or secondary amino, thiol or carboxyl). The prepolymer is then chain extended using an agent such as hydrazine, ethylene diamine, ethylene glycol or other active hydrogen bearing compounds. Many examples of diisocyanates are listed. Application of the polyurethane solution may be by brushing, spraying, gravure coating, roller coating or dipping, then drying. The poly-α-amino-acid may be applied from solution by brushing, spraying, gravure, roll, dip or knife coating, and many examples of the acids are listed. The amino acid solution may include other elastomeric polymers such as polybutene, natural rubber, polychloroprene, acrylonatrile-butadiene, copolymer, polybutadiene, chlorosulphonated polyethylene, polyvinyl acetate, vinyl chloride/vinyl acetate copolymer, polyalkyl (meth)acrylate, or urethane prepolymers.

Abstract: 272,155. Soc. Chimique de la Grande- Paroisse, Azote et Produits Chimiques. June 3, 1926, [Convention date]. Formaldehyde is obtained by the interaction of carbon monoxide with water or steam in the presence of catalysts. The catalysts used comprise magnesium, zinc, cadmium, manganese, tin, lead, antimony and bismuth, or their oxides or salts; suitable salts are formates or salts of the oxides with one another, e.g. magnesium antimonate, or with inactive oxides, e.g. magnesium silicate. The alkali metals and the metals chromium, molybdenum, tungsten, vanadium, uranium, niobium, copper, silver, gold, iron, cobalt, and nickel, or oxides of these metals, should not be present. The of the reaction chamber may be made of inert metals, e.g. aluminium, or tinned copper may be employed. Preferably the reaction, which is exothermic, is carried out under pressure and at temperatures of 200-600‹ C. In one example, a dried mixture of precipitated manganese carbonate and pumice is reduced in an aluminium tube with carbon monoxide, whereafter a mixture of carbon monoxide and steam is passed through the tube at a temperature of 220‹ C.: a dilute solution of formaldehyde is obtained by cooling the effluent gases. In another example, carbon monoxide is forced under a pressure of 450 atmospheres by a tube D through a catalyst C, comprising 2MgO.Sb2O3 on pumice, contained in a steel pressure-resisting tube A provided with an aluminium liner B, and at the same time heated water is forced in countercurrent from a tube E through the apparatus, which is maintained at a reaction temperature of 340‹ C.; water containing formaldehyde and dissolved carbon dioxide passes out by a pipe G. whilst by a pipe F escapes a mixture of carbon monoxide, water vapour and carbon dioxide, which may be returned to the apparatus after removal of the carbon dioxide. The Specification as open to inspection under Sect. 01 (3) (a) states that the carbon monoxide mav contain gases usually associated therewith, such as hydrogen, nitrogen. oxygen, and methane. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in and relating to the production of mixtures of nitrogen and hydrogen from ammonia synthesis
IPC: C01B3/48
Filed: 1924-09-24
Abstract: A mixture of nitrogen and hydrogen substantially free from methane is obtained by burning carbonaceous fuel continuously at a very high temperature, e.g. 1300 DEG  C., with highly preheated steam and air or enriched air, and causing the carbon monoxide so formed to react with steam in the presence of a catalyst.  The high temperature may be maintained by returning to the combustion chamber a large proportion of the available heat of the gaseous products of combustion in the form of preheat for the entering gases.  In order to obtain a mixture of hydrogen and nitrogen in the proportions required for the synthesis of ammonia, water-gas may be added to the mixture of gases before catalysis. Specification 242,741 is referred to.

Title: Improvement in fuel pumps, for internal combustion engines
IPC: F02M59/00
Filed: 1936-08-22
Abstract: 475,210. Supplying liquid fuel injection pumps. ACKERMANN, E. Aug. 22, 1936, No. 23132. [Class 7 (iii)] [Also in Group XXVIII] A fuel pump is provided with a member for metering compressed air, and valve means actuated by the compressed air to actuate fuel metering means and to open a port whereby the compressed air is fed to a chamber where it mixes with the fuel before it reaches the engine cylinder. Liquid fuel is supplied by a pump through a passage 47 to a chamber 3 and is drawn past a valve 11 into a chamber 5 by a pump plunger 12 held against a piston 24 by a spring 20. The compressed air is supplied through a passage 29 to a chamber 28. When a triangular port 30 in a rotating sleeve valve 25 registers with a passage 26, the air acts on the piston 24, to force fuel through a passage 14 and a slot 15 in the plunger 12, into a passage 17 leading to a chamber 43, where it is mixed with air, supplied through a passage 27 containing a check valve 46. To facilitate mixing, the mixture traverses helical passages in an insertion 44. The volume of the pump chamber 5 is adjusted by a pin 42 carried on a spindle 35 which can be displaced axially by a lever 40. Simultaneously, a spring 33 moves the valve 25 into contact with the end of the spindle to control the area of the port 30 which registers with the passage 26. In the construction shown in Fig. 3, the fuel is drawn from a chamber 60 past a suction valve 68 into the space inside a membrane 66. The compressed air is supplied through a passage 92 and when a port 53 in a rotating valve 52 registers with a passage 80, the air actuates a piston 74. As the piston 74 moves upwards, the head 91 of a spring-pressed piston 82 compresses the membrane 66 and forces the fuel past a valve 64 to the mixing device, until the bottom 71 of the membrane contacts with an adjustable stop 86. During further movement of the piston 74 the air passes through a passage 81 to the mixing device and a member 76 slides over the piston 82. In a multi-cylinder engine, the same member for metering the compressed air and the same compressor are used for all the engine cylinders.
