Abstract: 995,490. Spun dyed artificial filaments and films. BRITISH CELLOPHANE Ltd. Feb. 4, 1963 [Feb. 26, 1962], No. 7467/62. Heading B5B. Coloured shaped products such as filaments and films are produced by dispersing a vat dyestuff in an aqueous solution or dispersion of a filament- or film-forming substance, extruding the dispersion into a coagulating bath to form a shaped coagulated product such as a filament or film, treating the coagulated product with an aqueous solution of a reducing agent, heating the treated coagulated product while wet with this solution in an oxygen-free atmosphere at above 60‹ C., preferably above 90‹ C. to reduce the vat dyestuff dispersed in the product to its leuco form and subsequently subjecting the product to oxidizing conditions to oxidize the leuco form to the original vat dyestuff. The treated product may be heated by passage through an atmosphere of steam. It may be treated in a bath of the aqueous solution of the reducing agent at a temperature not exceeding 30‹ C. The reducing agent may be sodium hydrosulphite and the product may be treated with an aqueous solution of this agent rendered alkaline by the addition of sodium hydroxide. Alternatively, the shaped product may be treated with an alkaline aqueous solution of sodium formaldehyde sulphoxylate. The shaped product may be subjected to oxidizing conditions in a bleach bath. The aqueous solution of the filament or filament-forming substance may be viscose or an aqueous solution of a cellulose derivative other than cellulose xanthate, or if an alginate, a starch product, a vinyl compound, polyacrylonitrile or a protein. The shaped product may be a film or filaments of regenerated cellulose.

Abstract: 646,507. Hot-air engines. LUCAS, Ltd., J. Jan. 10, 1948, No. 825. '[Class 7(i)] [Also in Group XXIX] Apparatus for controlling the supply of liquid fuel to the combustion chamber of a hot-air engine and also the amount of motive air in the engine comprises a centrifugal fuel pump a, means such as the Bourdon tube e, responsive to the pressure of the motive air in the engine, for controlling the flow of fuel from the pump to the combustion chamber, and further means such as the valve k actuated by the pressure of liquid fuel under the control of a valve t responsive to an engine operating condition for controlling the amount of motive air within the system. The pump a is driven by the engine and supplied at constant head from a tank 3. The Bourdon tube e actuates a fuel valve b. The valve k is actuated by a spring-loaded piston m exposed through a pipe s to the pressure of liquid fuel controlled by the valve t. The valve t may be moved to connect the pipe s with the pump discharge through a passage 8 or with the pump suction through a passage 7. As shown the valve t is positioned in accordance with engine speed by means of diaphragm v actuated by the pressure difference across the pump against a spring w. Alternatively the valve t may be positioned by an engine-driven centrifugal governor. The valve k operates to admit pressure air to the motive air system, to which it is connected by a passage h by means of a passage i or to connect the system to the atmosphere by a passage j. Manual control of the valve k and therefore of the fuel valve b is effected by a lever r acting on the loading spring abutment p through a cam q. The valve k may alternatively or additionally be controlled by a valve responsive to the temperature in the combustion chamber. Where speed control of the fuel supply is already operative, a valve 10 in the fuel pipe is controlled according to the temperature of the combustion chamber.

Title: A process for the treatment with hydrogenating gases of extraction products of solidcarbonaceous materials
IPC: C10L9/04
Filed: 1937-01-12
Abstract: Valuable hydrocarbons are obtained by extracting solid carbonaceous materials, e.g. bituminous and brown coal, peat, &c. with solvents, adding an organic diluent of higher boiling point than the solvent, expelling the solvent by distillation and destructively hydrogenating the mixture of extract and diluent. Insoluble and infusible constituents are preferably removed after addition of the diluent. Solvents specified for the extraction treatment are tetrahydronaphthalene and mixtures thereof with phenols or middle oils of boiling point range between 170 and 230 DEG  C., and the extraction is carried out at 250-470 DEG  C. preferably in presence of catalysts, e.g. inorganic acids, organic carboxylic acids, halogens, halogen compounds of metalloids with heavy metals or their compounds, e.g. finely divided tin, lead, germanium, iron, nickel, or cobalt.  Diluents specified are tar fractions of boiling point above 230 DEG  C., e.g. middle oils obtained in a prior hydrogenation.  The destructive hydrogenation is carried out at temperatures from 250 to 500 DEG  C. under pressures of from 20-100 atmos. and in presence of catalysts comprising oxides and sulphides of heavy metals, e.g. tungsten, molybdenum, iron, chromium, &c. or organic acid salts of tin and zinc.  The catalyst may be brought onto carriers, e.g. brown coal small coke, alumina, bleaching earth.  The diluent may be recovered from the reaction products.  Gas flame coal admixed with 1,5 times its volume of a mixture of 80 per cent of tetrahydronaphthalene and 30 per cent cresol is heated at 400 DEG C., and under 100 atmos. pressure for 2 1/2 hours, 85 per cent of the organic substances contained in the coal being dissolved.  The resulting solution is freed from solid matter by filtration and 1,2 parts of heavy oil obtained from bituminous coal and containing 15 per cent components boiling below 325 DEG  C., are added and the mixture distilled up to 250 DEG  C. to remove tetrahydronaphthalene, cresol and naphthalene.  The remainder is subjected to destructive hydrogenation at 420 DEG  C., and 600 atmos. in the presence of 0,06 per cent tin oxalate and 0,9 per cent ammonium chloride with a throughput of 0,26 kgs. of extract per hour per litre reaction space. 100 Parts of extract are converted into 14 parts gaseous hydrocarbons and 86 parts of a Diesel oil free from asphalt.
