Title: Improvements in dyestuff emulsions for dyeing and printing textiles
IPC: D06P1/92
Filed: 1954-12-01
Abstract: A water-in-oil dyestuff emulsion for use in the dyeing or printing of textiles comprises, as the inner phase, an aqueous dyestuff- or dyestuff-intermediate-preparation and, as the continuous phase, a waterimmiscible, volatile, organic liquid, the emulsion containing a non-polymerizable emulsifying agent which is more soluble in the oil phase than in the aqueous phase and the amounts of emulsifying agent and organic liquid in the emulsion being 0.3-15 per cent by weight and 5-25 per cent by weight respectively, the emulsion being completely free from any filmforming or polymerizable or hardening agents.  Specified organic liquids are various hydrocarbons, chlorinated hydrocarbons, ketones and ethers.  Specified dyestuffs are vat, sulphur, sulphurcarbazole, direct, acid, azoic and acetate dyes. Specified emulsifying agents are condensation products of ethylene oxide with long-chain fatty acids or with alkyl phenols, aliphatic alcohols, fatty acid amides, alkyl amines, mercaptans and partial esters of polyhydric alcohols; ethylene oxide-propylene oxide condensation products; propylene oxide condensation products with long-chain alkyl amines; primary and secondary longchain aliphatic amines; fatty acid amides; long-chain aliphatic amine salts; aliphatic esters; alkanolamines; long-chain alkyl ammonium chlorides; dialkylsulphosuccinates and petroleum sulphonates. Electrolytes may be added to the aqueous phase to diminish the solubility of the emulsifier in this phase.  The dyestuff emulsions may be applied, e.g. as by padding or printing, to all kinds of natural or synthetic textile fibres such as those of cotton, ramie, jute, linen, sisal, wool, silk, mohair, camel's hair, cashmere, regenerated cellulose, cellulose acetate, casein, polyamides, polyesters and polyvinyl compounds.  Numerous emulsions containing vat dyes are described. Specifications 647,098, 733,099 and 759,293 are referred to.

Title: Improvements in or relating to liquid resistance controllers
Inventor: THORNHILL ALBERT
IPC: H01C10/02
Filed: 1954-12-01
Abstract: 790,774. Variable liquid resistances. GENERAL ELECTRIC CO., Ltd. Dec. 1, 1955 [Dec. 1, 1954], No. 34814/54. Class 37. In a variable liquid resistance of the kind comprising a pair of electrodes movable relative to each other and mounted in an insulating container to which liquid electrolyte is continuously circulated that electrode which is movable or both, if both are movable is or are in the form of a number of spaced vanes or plates, Figs. 1 and 2 show a variable liquid resistance controller of the kind such as described in Specifications 614,170 and 660,682, [Group XXXV], which are particularly useful for controlling polyphase alternating current induction motors. The electrolyte is circulated by means of a pump through insulating container 1 via pipe 4 and spout 3 in the container. Immersed in the electrolyte is a fixed electrode 2 having vanelike parallel plates 8 which are shaped at their bottoms to conform to the bottom of the container 1 and at their top to provide the required resistance control. The movable electrode comprises parallel vanes 10 carried upon a horizontal shaft 11 which is arranged to be driven towards and away from fixed electrode 2 and at the same time rotated about a horizontal axis by means of gear wheel 15 which meshes with fixed toothed rack 16 mounted outside the container, the shaft 11 being carried on rollers 17 which run on rails 18. In the maximum resistance position shown the extended part 14 of the vanes 10 of the movable electrode are directed away from the fixed electrode 2 and only a small part dips into the liquid electrolyte. As the movable electrode approaches the fixed one the extended parts 14 come into operation and finally interleave with the vanes of the fixed electrodes 2. By this means little effort is required to move the electrode to and fro and undue turbulence of the liquid electrolyte is prevented.

Title: Safety device for preventing the return of oxygen and backfiring into a gas piping
IPC: A62C4/02
Filed: 1936-12-18
Abstract: 490,929. Fluid - actuated valves. TORNOW, M. Dec. 18, 1936, No. 34892. Convention date, Dec. 21, 1935. [Class 135] The invention consists in a safety device for preventing the return of oxygen in a system of gas piping and stopping an explosion or back-fire, comprising a loaded valve and a check valve, the two valves being located respectively above and below a pair of diaphragms abutting one another at the centre and having acting surfaces of different areas, the spaces above and below the pair of diaphragms being connected with each other by a pipe. Gas enters at c and is taken away at d, e.g. for welding. A heavy valve a guided by lugs b is adapted to be opened by diaphragms e, f acting through a spring i the lower diaphragm being of larger area. A pipe o with valve l connects the spaces above and below the diaphragms. A check valve m guided by rods n is located below a member g carried by the lower diaphragm. The space between the diaphragms is connected by two pipes such as k with the outlet passage d, one of the pipes opening into this passage in the same direction as and the other in the opposite direction to the flow of gas so as to maintain a circulation. When gas is being taken off at d, the pressure below the diaphragms is higher than that above and the valve a is opened. Should oxygen return, these pressures are equalized and the valve a closes. If a back-fire occurs, the flame passes by way of the valve a and pipe o, but the pressure will have been transmitted to the space between the diaphragms, thus closing the check valve m and preventing the flame returning to the generator. Stops p, q limit the movements of the diaphragms.

Patent GB-448342-A (GB)
Title: Improvements in methods of coating abrasive grains
Filed: 1934-12-05
Abstract: 448,342. Abrasive articles. CARBORUNDUM CO., Niagara Falls, New York, U.S.A. Dec. 5, 1934, No. 34989. Convention date, Dec. 16, 1933. [Class 60] Abrasive grains for use in the manufacture of abrasive articles, such as sheet abrasives and wheels, are coated with a film of bonding material and dispersed in a fluid medium until the outer surface at least of the coating has hardened, the coated grains being thus rendered non-adherent so that they can be stored in the same way as uncoated grains until required for use. The coating materials may be of any kind which will harden or set under suitable conditions so that the grains will be non- adherent when stored or handled, but which can be subsequently rendered adherent when the abrasive article is to be formed from them ; for example, glues, varnishes, lacquers, synthetic resins, cellulose compounds, drying oils and other known bonding materials. The hardening may occur by evaporation of solvents, as in the case of lacquers, glues, cellulose solutions, &c. ; by heat, as in synthetic resins ; by the use of thermoplastic materials, such as shellac ; or by oxidation, as in materials having a base of tung or linseed oil. The mixed granular abrasive and bonding material may be sprayed from a nozzle into a gaseous medium, or one or more gaseous streams may be directed on to the mixture as it is extruded from an orifice so as to separate the coated grains. Another method consists in directing a stream of liquid bonding material into a stream of abrasive grains which are thus coated and dispersed. In a still further method, the coated grains are dispersed in a liquid; for example, grains coated with a liquid thermoplastic bond may be dropped into a cooled non-reactive and non- solvent liquid, and grains coated with a heathardenable bond into a heated and similarly inert liquid. Where the bond is hardened by evaporation of solvents, the mixture may be sprayed into a warm atmosphere, the air being subsequently passed to a recovery system and then to the spraying device to prevent the loss of solvent not recovered from it. Materials hardened by heat may be cured only sufficiently to harden the outer surface, and in any case are not cured sufficiently to render the bond infusible. An atmosphere rich in oxygen or ozone may be used for hardening bonding material which hardens by oxidation. Magnetic material may be added to the bonding material when it is desired to render the grains magnetic. Specification 431,062 is referred to.

Abstract: 159,497. Trent, W. E. Feb. 25, 1920, [Convention date]. Addition to 151,236. Surface-tension separating-processes. -The agglomerated mass obtained in accordance with the parent. Specification is distilled in order to recover the agglomerating-agent together with any volatile constituents of the coal. The condensed vapours may subsequently be used to agglomerate further carbonaceous particles. Preferably after being thinned with hydrocarbon liquid and commingled with air or gas, the mass is supplied from a hopper 46 into a , pipe 47 extending through a retort 45, which is heated by burning a combustible mixture delivered through a pipe .48. The material is carried through the retort in the current produced by a pump 50 and the treating-agent is volatilized together with the volatile constituents of the solid particles which latter may be separted in a dry settling-chamber 49. The distilled substances pass off through a pipe 51. Separation of fine ash particles contained in the carbonaceous matter is facilitated by expelling the volatile content explosively by heating with sufficient rapidity or by subsequently passing the particles through a zone of lower pressure. The volatile constituents and carbon particles may be delivered to a wet collecting chamber 54 receiving water from a pipe 55. Agitation of the condensed vapours causes the carbon and oils to agglomerate and exclude the non-carbonaceous particles and water.
