Title: Process for the conversion of carbon monoxide with hydrogen
IPC: B01J23/745
Filed: 1939-11-06
Abstract: 538,225. Hydrocarbons; catalysts. POTTS, H. E. (Naamlooze Vennootschap Internationale Koolwaterstoffen Synthese Maatschappij (International Hydrocarbon Synthesis Co.)). Nov. 6, 1939, No. 29430. [Class 2 (iii)] [Also in Group III] An iron catalyst for use in the preparation of hydrocarbons from mixtures of carbon monoxide and hydrogen or the high pressure hydrogenation of oils in the liquid phase is made by treating compact iron (i.e. iron in the form of pieces of which two dimensions are at least 2 mm. and 1 mm. respectively) with oxidizing gases at high temperatures, e.g. 700-900C., and for such a long time that the iron is completely converted into iron oxide without melting the iron or the iron oxide formed, and subsequently reducing the iron oxide to metal by treatment with reducing gases. The catalyst may be prepared from sheet iron in the form of hollow bodies, e.g. Raschig rings. The activity of the catalysts may be increased by additions of alkali metal compounds, e.g. halides, phosphates or borates of potassium, sodium, lithium or caesium. These may be added in the dry state or as aqueous solutions before, during or after the treatment with reducing gases. The activity of the catalysts may be further increased by addition of aluminium oxide or hydroxide, silica, or oxides, hydroxides, carbonates or halogenides of copper, titanium, manganese, tungsten, molybdenum, chromium, thorium, cerium, zirconium or other rare earths. In an example, Raschig rings of 10 mm. diameter, made of sheet iron of 1.5 mm. thickness, are treated with air at 700C. until completely oxidized, reduced by means of hydrogen at 600C. and subsequently treated with borax solution. Water gas containing carbon monoxide and hydrogen in volumetric proportions of 4: 5 is passed over the catalyst at 320 C. and under a pressure of 20 atmospheres in a circulation process as described in Specification 518,372. A mixture of hydrocarbons within the boiling range of benzine is obtained.

Title: Improvements in and relating to surface coatings on panel, slab or like material
IPC: B32B27/00
Filed: 1956-09-26
Abstract: 843,783. Laminates. SPUY, M. VAN DER. Sept. 26, 1956 [Oct. 10, 1955; Oct. 12, 1955], No. 29446/56. Class 140. A decorative rigid laminate is made by applying a flexible sheet coated on one or both sides with a resin hardenable at atmospheric pressure to a flat mould surface of a plane template made of plate-glass so as to form a layer of the resin between the flexible sheet and the glass, securing a rigid backing-sheet to the other side of the flexible sheet by means of resin, hardening the resin, and removing the product from the mould surface. The flexible sheet, which may be paper, thin fabric of natural, synthetic, or glass fibre, plastic foil, or metal foil, may be coloured, or provided with a design or legend, the resin being transparent or translucent so that the design shows through. Alternatively a plain, undecorated sheet may be used with an opaque coloured resin. Polyester or melamine-aldehyde resins may be used. The plate-glass may be of highly-polished mirror glass quality. The rigid backing may be a wood fibre or chip-board, plywood, asbestos cement, a cellulose-asbestos board, sheet iron which may be tinned or galvanized, or aluminium sheet. The plate-glass moulding surface may be given a release coating of wax, e.g. carnauba, which may be applied as an emulsion, a wax polish, a silicone oil or solution, or an aqueous solution of polyvinyl alcohol. Polymerization of the resin may be accelerated by radiation from infra-red and other lamps placed below the glass mould. After the resin has gelled, the article may be stripped from the glass template for completion of the cure. The products are suitable for furniture, wall panels, or table tops, name, number, or public notice plates. Both surfaces of a panel may be furnished with a design. As shown, patterned paper is led from a roll 5 through a drier and heater 6, around rollers 9-11 immersed in liquid resin or resin solution in a tank 8 and is applied by roller 13 to a series of plate-glass templates mounted on frames la, 1b, 1c which are mounted on rails and move at constant speed to the right of the diagram. The resin is pregelled, e.g. by heat, and a stiff backing 15, resin-coated on its underside, is passed with its front end under roller 18 which presses it on to the paper. The rear end of the backing 15 is supported elastically by means 17a depending from roller 17. Roller 18 may be supported at a controlled distance from the glass surface. The assembly then passes through a heated curing chamber.

Title: Improvements in printing machines
IPC: B65H7/02
Filed: 1947-11-06
Abstract: 630,056. Printing-machines. FURNIVAL & CO., Ltd., FURNIVAL F. S., and BALL W. F. Nov. 6, 1947, No. 29599. [Class 100 (ii)] A printing-machine is constructed so that the printing-cylinders are separated and the sheet-feed mechanism tripped if a sheet is not fed correctly, or if the electrical driving means for the press is stopped. The control means comprises a pair of electromagnets 13, 25 arranged in series with the driving motor, so that the magnets are normally energized and normally permit the action of front stops a<SP>2</SP> which rise to permit feed of the sheets, and also control mechanism for actuating eccentric bearings 34 to a position in which the printing cylinder C (here shown as an offset roller) is in operative position. The electrical circuit comprises micro switches 4 which are opened if one or more of a series of feelers 1 are permitted owing to incorrect positioning or absence of a sheet on the feed-board a to pass through an aperture 5 in the feed-board a and the consequent breaking of the circuit stops the machine and demagnetizes the magnets 13, 25. The armature 14 of magnet 13 then drops and actuates a lever 15 which trips lever-and-link mechanism 20, 19, 171, the normal function of which is to raise the front stops a<SP>2</SP>, and also to raise fingers 161 through the slots 5 in the feed table a so as to keep the feelers 1 raised when a sheet is not passing under the feelers. The armature 26 of magnet 25 controls the position of a recipocating pawl 27 having curved ends which can engage either a roller 31 or 35 of a lever 32 which is pivoted to a link 33 connected to an eccentric bearing 34 of the cylinder C. When the pawl 27 is held raised by the action of the armature 26 on a projection 30 on the pawl 27, the cylinder C is held in printing position, but when magnet 25 is demagnetized the roller 35 is engaged and the lever 30 moved clockwise to move the cylinder C out of printing position. By means of switches b, bl the machine may be set either so that the feed mechanism is tripped while the printing- cylinders are in contact while inking-up, or the printing-cylinders may be tripped and the feed mechanism operated while setting the feed mechanism. The switches b, b<SP>1</SP> are only effective if a master switch b<SP>2</SP> is closed. The feed mechanism may be tripped by a hand lever 24.
