Abstract: 1413857 Chromium carbide layers; forming Cr carbide electrolytically TOYOTA CHUO KENKYUSHO KK 6 Nov 1973 [16 Nov 1972 12 April 1973] 51368/73 Headings C7B and C7F Boric oxide and/or a borate is heated to form a molten bath, a metal block containing Cr is dipped therein and made anodic so that it dissolves, and an iron, Fe alloy, or cemented carbide article containing at least 0.06%C is immersed in the bath, to receive a chromium carbide coating. The bath may contain B 2 O 3 , Na 2 B 4 O 7 , or K 2 B 4 O 7 , and its viscosity may be reduced by addition of NaCl, KCl, NaF, P oxides, hydroxides, sulphates, carbonates, or nitrates; the block is pure Cr or alloy such as ferro-chromium, and using 0.1-10A/cm<SP>2</SP> for 30 min-5 hr this dissolves to give about 1%Cr in the bath; immersion of an article at 800-1100‹C for 1-30 hr under air or inert gas after or during dissolution of Cr gives a Cr carbide layer. The cemented carbide substrate is WC/Co optionally containing TiC, NbC, or TaC.

Title: Gasification of carbonaceous solids
IPC: C02F11/10
Filed: 1972-11-13
Abstract: 1407445 Gaseous hydrocarbons OCCIDENTAL PETROLEUM CORP 13 Nov 1972 52247/72 Heading C5E Gaseous hydrocarbons having 1 to 7 carbon atoms are produced by forming a turbulent stream composed of an inert carrier gas, water, hot particulate char and particulate carbonaceous solids, the solids having an individual maximum particle dimension of less than 1À0 inch, the stream having the solids and water initimately admixed with and entrained within the gaseous portion of the stream, the water being present in an amount of at least 2À0%, e.g. 7 to 18%, of the dry weight of the carbonaceous solids in the stream; passing the stream into a pyrolysis zone wherein heat exchange takes place between components of the stream and the carbonaceous solids are heated to a pyrolysis temperature of 650‹ to 1400‹ C. during a residence time, e.g. less than 10 seconds, in the zone such that at least a portion of the carbonaceous solids are converted to gaseous hydrocarbons containing from 1 to 7 carbon atoms; removing the product stream from the pyrolysis zone; and recovering the gaseous hydrocarbons from the product stream. The turbulent stream is defined as a stream of gas which, when flowing through the pyrolysis zone, e.g. a pipe-shaped reactor vessel, has a flow that is turbulent in nature, e.g. having a Reynolds flow Index Number greater than 2000. The carrier gas must not be deleteriously reactive with the char, organic solids or pyrolysis product values, and should thus be substantially free of air and oxygen; examples specified are nitrogen, argon, methane, hydrogen, hydrogen-enriched gas, carbon monoxide, carbon dioxide, flue gases and steam. The carbonaceous solids may comprise municipal, industrial and/or agricultural waste material. The gaseous product may be separated into product components and may consist mainly of ethylene. A substantial proportion of the heat supplied to the carbonaceous solids in the pyrolysis zone may be provided by sensible heat of the char in the turbulent stream; some of the heat may be supplied by indirect heating means. A portion of the solids content of the product stream may be separated therefrom, heated to a suitable temperature and thereafter recycled to the pyrolysis zone as the hot particulate char component of the turbulent stream to supply a substantial portion, e.g. substantially all, of the heat required by the carbonaceous solids in the pyrolysis zone.

Abstract: 1465988 Mould-release agents BALL BROS RESEARCH CORP 4 Dec 1974 [13 Dec 1973] 52383/74 Heading C5F A mould-release agent comprises a dispersion of a mixture of a solid lubricant, a carrier, a binder and a derivative of sym-triazine. The solid lubricant may be graphite, the carrier aqueous or organic and the binder a silicate, a polyimide, a polyarylene sulphide, a polybenzimidazole or an organosilicon polymer. A preferred silicate binder is a mixture of sodium silicate and zinc oxide but organic silicates may also be used. Wetting agents, pigments or fillers may be incorporated, as also may antioxidants. The agent may be applied to a mould surface, e.g. for glass, which is then heated to drive off the carrier and leave a thin coating of solid lubricant.

Title: Continuous generation of catalysts for hydrocarbon conversion  processes
IPC: C07C15/00
Filed: 1973-11-13
Abstract: 1430437 Hydrocarbon conversion LUMMUS CO 13 Nov 1973 [13 Nov 1972] 52585/73 Heading C5E [Also in Division B1] Hydrocarbons are converted by continuously generating an aluminium halide by continuously contacting aluminium metal with a hydrogen halide and/or a halogen, continuously adding the aluminium halide to a bed of a Group VIII noble metal supported on a refractory oxide to continuously generate a catalyst and continuously contacting the hydrocarbon feed with the continuously generated catalyst. The hydrogen halide and/or halogen may be premixed with the feed and either first contacted with aluminium metal and the resultant feedaluminium halide mixture contacted with the supported noble metal or contacted with a mixed bed of aluminium metal and supported nobel metal. Alternatively the aluminium halide may be separately generated and added to the bed of supported noble metal separately from the feed. The process may be used in the isomerization, alkylation, transalkylation-disproportionation, hydrocracking and hydrogenation of hydrocarbons. An example describes the production of a supersonic aircraft jet kerosene by feeding a liquid jet kerosene fraction saturated with hydrogen chloride and mixed with hydrogen through a bed of aluminium metal into a bed of platinum on alumina in a reactor at 392-394‹ F. at 500 p.s.i.g. and an LHSV of 0À7.

During the travel from the end brackets 10, the flap 16 is in its closed position as it slides over tracks 20 (22) but when the trough reaches the end brackets 11, the flap is released by gravity over the curved end portions of the tracks to discharge the sample down a shoot 48 into a container 50 which can be removed from beneath the shoot along guide rods passing through mountings 52, 54. The trough may be set to dwell in the discharge position and may be moved to and fro along the guide rails 6 (8) until a sufficient sample has been taken from the falling material. Buffers 13, 35 may be provided on the guide rails. A manually-operated control valve may be provided in addition to a solenoid operated valve 42 in case of failure of the latter. In an alternative embodiment, the flap 16 may be arranged to open adjacent the brackets 10 as well.
