Abstract: 1,172,425. Photographic transfer processes. MINNESOTA MINING & MFG. CO. Feb. 2, 1967 [Feb. 3, 1966], No.5186/67. Heading G2C. A receptor sheet comprises of layer of silver salt of an organic acid, a di-tertiaryalkyl substituted phenol, and an image amplifier which is a compound of a metal which can exist in more than one valeney. This sheet is used to receive a latent image produced by imagewise reflex exposing a photo-sensitive sheet containing 4 methray naphthol and contacting the two sheets whilst heating which produces a silver image. The image amplifier produces a denser and more stable image and specified amplifiers are stannous stearate, laurate oxalate and sulphate; cupric stearate, acetate and tartrate; cuprous and tungstic oxide; cobalt acetate and stearate; manganese acetate and stearate; lead acetate; gold resinate; vanadyl sulphate and uranium and uranyl acetate. The preferred composition of receptor sheet is an equimolar mixture of silver behenate and behenic acid, phthalizinone as toner; 2, 6 di-tertiaryalkyl-pcresol, zinc oxide, terpene resin, a polymeric binder and the image amplifier. The receptor sheet may contain a toner for the silver image e.g. 1(2H)-phthaluzinone.

Abstract: 557,551. Stroboscopic apparatus. SELFPRIMING PUMP & ENGINEERING CO., Ltd., and MOUTRAN, F. April 23, 1942, No. 5481. [Class 97 (i)] In means for stroboscopically illuminating periodically moving parts comprising a motor variably driving an electric make-and-break device, a transformer having its primary circuit controlled by the make-and-break device, a discharge lamp in the secondary circuit of the transformer, and a speedometer indicating the motor speed, the make-and-break device is a distributer such as is used in motor-car ignition systems and has a breaker cam or the equivalent producing a plurality of breaks per revolution ; the transformer may be a high tension coil as used in motor car ignition systems. As shown, a neon lamp 22, reflector 23, motor 13, speedometer 15, rheostat 17, carignition transformer 21, rotary distributer 20, and cut-out 30, are assembled in a metal case 10 having ventilator louvres 11 and a carrying handle 12. The apparatus is wired as in an ignition circuit, the primary circuit being supplied from a 12 volt source under the control of a switch 29, and the lamp being in the high tension circuit. The motor 13 rotates the distributer 20 through a flexible coupling 19, and its shaft 14 is coupled to the speedometer 15 ; its circuit controlled by a switch 26, is supplied from a mains source, and includes the rheostat 17 controllable by a hand wheel 18 to vary the motor speed. Wide variations of speed may be determined by suitable choice of the motor and number of breaks per revolution of the distributer, the speed of the periodically moving part, lighted by the lamp 22, being obtained by multiplying the speed of the motor shaft by the number of breaks per revolution, when the illuminated part appears to be stationary.

Title: Improvements in, or relating to cooling towers
IPC: F28C1/16
Filed: 1931-02-24
Abstract: An electric field is used to recover water from the vapour leaving a cooling-tower.  The field is created by a network a, b covered by a mesh k which is generally between 40 mm. by 40 mm. and 70 mm. by 70 mm.  The network may consist of coaxial erect cones or a single cone erect or inverted as well as the form shown.  A cable m carrying a weight n serves to steady the network and acts as a downward path for the moisture deposited on the cones as well as forming the electric connection to the network. The wires j supporting the mesh are of the order of 0,4 mm. in diameter to allow water to flow readily along them, and all wires in the cones must have a downward slope to cause this <PICT:0363902/III/1> flow.  Any other suitable metallic material may be placed on the wires j instead of meshwork.

Title: Improvements relating to the thermal treatment of hydrocarbon gases
IPC: C07C2/00
Filed: 1931-02-25
Abstract: The residual gases containing carbon monoxide and hydrogen from the process of heat treatment of hydrocarbon gases as described in Specification 309,455, [Class 90, Non-metallic elements], carried out by admixing the gases with a heated carrier gas, is utilized to produce carbon black either by heating the gases to a high temperature or by burning them in a restricted supply of air.ALSO:The heat treatment of hydrocarbon gases, such as natural gas, gases from cracking plants, &c. to obtain aromatic hydrocarbons and olefines, as described in Specification 309,455, [Class 2 (iii), Dyes &c.], is carried out by mixing the gases with a heated gas which serves as the vehicle for heat.  The gas, which may be the permanent gases resulting from the process is heated to 1800-2000 DEG  C. and is mixed with the gas to be treated so as to obtain a mixture having a temperature of 650-1250 DEG  C. or higher or, if the gas contains olefines a temperature of 450-750 DEG  C.  The p  gas may be preheated before admixture and the mixture may be effected in heated or lagged reaction vessels or tubes.  The mixture may be made by passing one gas through an annular nozzle surrounding a nozzle through which the other gas is supplied.  The heated gas may be admitted at a number of positions in the course of the gas through the reaction tubes.  The reaction may be carried out in presence of superheated steam.  Catalysts may be placed in the reaction vessel or tubes or these may be made of metal or material which acts catalytically or which avoids or minimizes the deposit of carbon. The mixed gases after treatment pass through a tar separator and through an expansion vessel or scrubber and through a vessel containing activated carbon or other adsorbent.  The olefines formed may be used to produce alcohols or esters and the liquid aromatics and higher olefines to produce antidetonating motor spirit.  Carbon monoxide and hydrogen contained in the residual gas may be used to produce oxygenated hydrocarbon derivatives such as alcohols, aldehydes, ketones, acids, &c. or may be heated to a high temperature or burnt with a restricted supply of air to produce carbon black.

Abstract: Resinous condensation products are purified by treating a solution of them with a washing fluid capable of dissolving undesired constituents, incompletely condensed products and impurities and evaporating the solvent liquid from the mixture in order to precipitate the artificial resin as a pulverulent resin. Resins to which the process is applicable include condensation products of aldehydes with phenols, urea or thiourea, or polyhydric alcohol-polybasic acid condensation products. Suitable solvent liquids include methyl alcohol, ethyl alcohol and acetone whilst washing liquids include benzene, toluene and water.
