Filed: 1973-06-27
Abstract: 1441277 Catalytic production of methane from methanol DAVY POWERGAS Ltd 14 June 1974 [27 June 1973] 30664/73 Heading C5E In a process for producing methane from methanol, a mixture of steam and methanol is passed over a catalyst which is free from any Group VIII elements in metallic form, and which will catalyse the CO shift reaction, and the products are thereafter methanated. The preferred catalyst for the methanol gasification is an Fe 2 O 3 /Cr 2 O 3  mixture. The molar ratio of steam to methanol in the feed gas lies between 0À2: 1 to 20 : 1, and may be adjusted to control the reaction temperature. The product gases from the methanol gasification are reacted, using a Group VIII metallic catalyst, in a conventional methanation process. An added hydrocarbon feedstock (LPG or naphtha) may be injected into the product gases and pass therewith to the methanation stage. A multistage process may be adopted in which the gasification and methanation sequence is followed by injection of further methanol and additional gasification and methanation steps.

Title: Pneumatic vibrator
IPC: B06B1/18
Filed: 1974-07-16
Abstract: 1472568 Vibrators OSBORN MFG CORP 16 July 1974 [24 Aug 1973] 31454/74 Heading F2X A pneumatic vibrator includes a bore 14 in which a plunger B is reciprocatingly positioned for movement between the position shown (or striking position) and an exhaust position, an air inlet port 26, 28 and an air exhaust port 72 communicating with the bore 14 on opposite sides of the plunger B, and exhaust passage means through the plunger B for exhausting air from the inlet port 26, 28 to the exhaust port 72 in the exhaust position of the plunger B. End caps C, D are screwthreaded into the ends of the vibrator body 12, inlet port 26, 28 extending through the end cap C and exhaust port 72 through the end cap D. A cylindrical striker insert E made of a material having low sound transmitting characteristics, e.g. natural or synthetic rubber, is tightly fitted within a cylindrical recess 30 formed in end cap C. Compressed air from the inlet port 26, 28 passes through an axial hole 34 and at least one radially extending notch formed in the insert E and enters an annular space 44 surrounding the frusto-conical striker end portion of the plunger B. The compressed air forces the plunger B away from the insert E toward its exhaust position against the biasing action of a coil spring 64 housed within an axial bore 58 of the plunger B. As the plunger B moves to the right, communication is established between the annular space 44 and the exhaust port 72 via a circumferential groove 50 formed in the bore 14 and radial bores 60, an axial bore 102 and the larger diameter axial bore 58 of the plunger B. The exhausting action occurs before the plunger end makes contact with the end surface 70 of end cap D. An enlarged outwardly opening flared recess 74 is formed in end cap D coaxial with exhaust port 72, a noise muffler 76 of metal wool or multi-layer metal mesh being held within this recess by means of a fine screen 78, the muffler and screen together preventing foreign particles from entering the bore 14 through the exhaust port 72. End cap D has an enlarged cylindrical recess 104 extending inward from end surface 70 for receiving the end of spring 64. The large cavity defined by the bores 58, 104 and a portion of bore 14 allows a substantial quantity of air to accumulate under slight pressure for aiding spring 64 in shifting plunger B back to its striking position. The repeated striking of insert E by plunger B rapidly builds up heat as a result of internal friction, which heat is however dissipated by the continuous flow of cool compressed air in contact with insert E.

Title: Improvements in colouring water-insoluble plastic masses
IPC: D06P3/00
Filed: 1933-11-13
Abstract: Plastic masses consisting wholly or partly of water-insoluble polymerization products of unsaturated compounds are coloured by treating them with aqueous suspensions of dyestuffs which are difficulty soluble or insoluble in water and which are suitable for dyeing cellulose esters in aqueous media.  Suitable polymerization products are those of vinyl chloride, vinyl esters, e.g. vinyl acetate, vinyl ethers, acrylic acid esters or acrylic nitrile, or interpolymerization products of these compounds, or of one of these compounds with polymerizable aromatic hydrocarbons provided the former is in excess, also conversion products of these polymerization products, e.g. those produced by chlorination, or by condensation of polymerized vinyl alcohols with aldehydes.  Additions such as softening agents may be used.  The polymerization products may be coloured in the form of films, threads, plates, rods, or tubes.  The colouring is carried out at ordinary or moderately elevated temperature, e.g. 50--60 DEG  C.  Dispersing agents, e.g. soaps, or similar substances, e.g. turkey red oils, alkylated naphthalenesulphonic acids, polymerized ethylene oxide, taurides of high fatty acids, fatty alcohol sulphonates, molasses or sulphite cellulose waste liquor may be added to the dyebath.  Suitable dyestuffs are: aminoanthraquinones, e.g. a -aminoanthraquinone, alkylated aminoanthraquinones and hydroxyaminoanthraquinones, nitroarylamines, e.g. nitroaminoanthraquinones, aminoazo compounds, pyrazolone dyestuffs, the coupling products of diazotized aromatic bases with N-hydroxyethylated aromatic amines or aminocarboxylic acids, or the salts of dyestuff bases with organic acids, e.g. the benzoate of the base of Malachite Green. In examples: (1) combs from an interpolymerization product of vinyl chloride and acetate are coloured blue from an aqueous suspension of 1-amino-4-methylanthraquinone; articles from interpolymerization products of vinyl chloride and acrylic acid esters or from chlorinated polyvinyl chloride may be similarly coloured; (2) buttons from an interpolymerization product of vinyl chloride and methyl acrylate are coloured lemon yellow from an aqueous suspension of the dyestuff aniline --> 1-(2<1>-chlorophenyl)-3-methyl-5-pyrazolone; (3) articles, e.g. plates, from a polyvinyl alcohol-acetaldehyde condensation product are coloured similarly; (4) articles from the polymerization product of (1) are coloured yellow from an aqueous suspension of aminoazobenzene, prepared by dissolving the dyestuff in alcohol and pouring the solution into an aqueous soap solution; (5) combs from the polymerization product of (1) and zinc oxide are coloured pink from a suspension of 1 - amino - 4 - hydroxyanthraquinone in water containing acetone.
