Patent GB-478486-A (GB)
Title: Process for the recovery of hydrocarbons
IPC: C07C7/12
Filed: 1937-06-07
Abstract: In the recovery of hydrocarbons from gas mixtures highly saturated with water vapour, the gases are heated prior to the adsorption to such a temperature that the relative humidity is reduced below 90 per cent, preferably below 70 per cent.  The heating may be effected by the addition of a portion of the gas under treatment, or of other gases, which has been heated to a temperature above the required temperature.  When the gas to be treated requires to be cooled before treatment, the reheating may be effected by passing the gas through a number of coolers in parallel from one or more of which the cooling agent is shut off, and then reuniting the streams.

Title: Improvements in or relating to the continuous production of a metal deposit
IPC: B22D7/00
Filed: 1955-06-02
Abstract: 809,412. Continuous - - casting - machine; making tubes and sheets; shearing. BRENNAN, J. B. June 2, 1955, No. 15823/55. Classes 83 (1), 83 (2) and 83 (4). In a method of continous casting, solid metal is fed into a heating zone where it is melted, the molten metal is directed on to a rotating member and thereby scattered on to annular backing means where it solidifies, and the resulting tubular deposit is progressively withdrawn. As shown, metal-bars 85 are fed into chamber 82, in which there is maintained subatmospheric pressure and/or an inert atmosphere, and pass through induction-coils 86 which melt their lower ends. High-pressure gas issuing from nozzles 88 atomizes and strips metal from said bars to deposit it on a rotating- table 72, from which it is thrown on to a wall 92 to form a tube 93 surrounding said table. The tube, as it is withdrawn by densifying- rollers 104-107, is heated on one side and cooled on the other by induction-heaters 96, 100 and cooling-jackets 98, 102. The tube may finally be cut into longitudinal strips by cutting- means 114 which consists, as shown in Fig. 4, of a grooved-roller 115 and co-operating knifeedged roller 116 biased by a spring 117 towards roller 115. Induction-coils 90 may be utilized to vaporize the metal particles prior to their deposition on wall 92. Laminates may be produced by depositing layers of metal on backing means consisting of a porous-strip of metal formed by this method, a quartz fibre-base, or paper.

Abstract: 809,956. Iron manufacture; carbonyl processes; extracting metals; coating with metals; granulating metals. BRENNAN, J. B. June 2, 1955, No. 15824/55. Classes 72, 82(1) and 82(2) Powdered metals are obtained by feeding molten material, namely metal or metal carbonyl, into a rotating chamber having orifices in the peripheral wall, the material passing through the orifices to form the metal. Metals may be powdered unchanged, or a metal carbonyl may be atomized into a heated space to decompose, thus giving the metal. A halide may similarly be used to yield the metal. The metal producing unit is used to coat metal or non-metal materials with a metallic coating to form a porous strip, and the coating may be stripped off the backing if desired. The coating may be subjected to compaction by being passed between rolls whilst heated by H.F. means. The coating metals include iron and nickel and bases specified are metal, paper, glass, ceramic, quartz, textiles and synthetic materials. Molten material is supplied to a centrifuge 3 and issues through orifices 6 to meet a gas blast from nozzles 14 arid the powdered metal impinges on an endless band 9 kept at a suitable temperature by the shoe 12. A knife 21 strips off the coating and it is consolidated by rollers 15 before being spooled. Heating means 8 and 23 are provided, the former being optionally used when atomizing metals. H.F. heating may be substituted for the gas jets shown. The centrifuge is rotated by a pulley 17. Specification 747.962 is referred to.

Title: Catalytic conversion of hydrocarbons and the preparation of catalysts therefor
IPC: B01J21/04
Filed: 1945-06-21
Abstract: <PICT:0595742/III/1> Boric oxide catalysts are produced by impregnating adsorptive base material consisting predominantly of alumina with mixed vapours of steam and boric acid at 140-590 DEG C., preferably at a combined vapour pressure below one atmosphere, e.g., by the addition of diluent gases.  Suitable boric oxide concentrations vary from 2.9 x 10-4 grams per square metre of surface for dehydrogenation to 10 x 10-4 g.p.s.m. for cracking.  The base preferably contains 2-10 per cent. water, 2-15 per cent. silica, has a density of 0.6-1 and an available surface of at least 150 square metres per gram.  It may contain minor amounts of oxides of calcium, barium, strontium, magnesium, beryllium, p  titanium, tin, thorium, zirconium, bismuth, chromium, molybdenum and tungsten.  In the fluid catalyst system shown, hydrocarbon oil or gas entering at 61, charged with finely divided catalyst from the secondary regenerator 63 passes to the hindered settling reactor 64 and separator 66.  Cracked gases pass to a fractionator 76 heavy oil being withdrawn at 78 while steam, boric acid vapour, and light gases pass to a cooler 80 and separator 81. Uncondensed hydrocarbon gases after compression and cooling pass to a separator 83 and out of the system, part being diverted to regenerator leg 62 to displace air in the catalyst. Light and heavy gasoline from the separator leave at 85.  Boric acid solution from separator 81, fortified in the saturators 91 passes to the boiler 71, preferably maintained at over 4.5 atmospheres and below 3 per cent. boric acid concentration.  Catalyst and make up base material charged at 70 pass down the baffled stripping regenerating impregnator 67 countercurrent to vapours of steam and boric acid fed from boiler 71 via superheater 72 and expansion valve 73 and diluted with hydrocarbon gases bled from the separator 83 via heater 88.  Hydrocarbon oils stripped from the catalyst pass at 75 to the fractionator 76.  Impregnated catalyst is conveyed by an air current 69 to the regenerator 63 where carbon deposits are burnt off. Impregnation thus occurs at the reactor temperature, e.g., 980 DEG F. or below and in the presence of hydrocarbon oils and gases which protect the base against damage by steam.  The secondary regenerator 63 may operate at, e.g., 1100-1400 DEG F.  In modifications ordinary bottom draw off reactors and impregnators are used in a similar cycle, the make up material being charged to the second stage regenerator.  Fortified boric acid solution may be charged direct to hot catalyst from the reactor thus dispensing with the boiler. Alternatively catalyst may cycle in parallel streams from the second stage regenerator to the reactor and to the impregnator. Impregnation may thus take place at a much lower temperature while excessive regenerator temperatures may be avoided.  Examples are given.

In the arrangement shown in Fig. 1, the relay armature H carries three core parts and is drawn away from the coils F and C by a spring R. A contact arm P moves with the armature Hand co-operates with a contact arm N which moves with the main switch. As the main switch closes, the arm N moves towards the arm P which, however, moves away under the action of the setting- magnet. When the current in the relay coils F falls off owing to the speeding up of the motor, the arm P comes into engagement with the arm N under the action of the spring R and the circuit of the actuating-coil L of the contactor is thereby completed and resistance sections G short-circuited. A construction of relay is described and shown.
