Abstract: 674,318. Flexible cables. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. Nov. 24, 1950 [Nov. 29, 1949], No. 28787/50. Class 36. A flexible electric cable having more than two twisted cores, each comprising a flexible conductor 1 insulated with a layer 2 of elastic material, is constructed so that each core is connected in the longitudinal direction to each adjacent core through less than <SP>1</SP>/ 5 th, and preferably less than 1/ 6 th of the periphery of its insulation. The cable may be made by extruding the layer 2 simultaneously on to the conductor 1, each of which may be marked by winding with coloured threads, and twisting the assembly while the insulation is still soft. Alternatively the conductors may be individually covered with insulation of different colours, and the cores then twisted and welded or stuck together. A longitudinal duct may be provided in the insulation to reduce the tendency to kinking and improve the flexibility of the cable.

Abstract: 1,035,443. Random dyeing cellulosic yarn. ASTRO DYE WORKS Inc. July 22, 1963, No. 28998/63. Heading D1B. Random dyeing cellulosic yarn is achieved by injecting into at least one selected portion of a round package of yarn an aqueous alkaline solution of a reactive dye and allowing the so-treated package to stand until the dye has reacted with the yarn. The specified cellulosic materials are cotton, viscose, cuprammonium, nitrocellulose, cellulose acetate and triacetate. The dye solution may be injected into the wound package by means of a hollow injection needle perforated along its length, forced air or a perforated cone under pressure. Figures 2 and 3 show a specific embodiment in which the round package 11 with dyed areas 12-14 is shown in elevation and cross-section. After the dyestuff has reacted with the fibre (a) the package may be stored in the damp condition in which case a mildew resist agent should be present in the dye liquor, (b) the yarn may be tufted into a fabric, scoured and bleached with H 2 0 2  or (c) the yarn may be scoured and dried, e.g. in a package dyeing machine. The dye liquor advantageously contains a melting agent, e.g. an ethylene oxide condensate. Examples of dyeing cotton viscose and cuprammonium rayon are given.

Title: Electrogasdynamic precipitation
IPC: B03C3/013
Filed: 1967-11-14
Abstract: 1,213,547. Electrogasdynamic precipitation GOURDINE SYSTEMS Inc. 14 Nov., 1967 [15 Nov., 1966], No. 29052/68. Divided out of 1,212,539. Heading C1A. [Also in Divisions B1 and B2]  A selected gaseous phase is separated from a mixture of gaseous phases by causing the gaseous mixture to flow along a bounded flow path, particulating the selected phase either by condensation or by injecting particles into the flowing gas stream, and removing the particles from the remaining gaseous phases by electrogasdynamic precipitation. The particulation may be by condensation of the gas by decrease in ambient temperature, adsorption or absorption of the gas by injected solid or liquid, by formation of particles by chemical reaction of the gas and injected particles, or the injected particles may catalyse a reaction between two gases to form a product that is, or may be, particulated. In the embodiment described, dust is first removed from a combustion gas containing SO 2  by electrogasdynamic precipitation at 213. Then V 2 O 5  particles are injected into the gas stream at 220, and catalyse reaction (at about 600‹ C.) between SO 2  and O 2  to form SO 3 , after which the gas is cooled to about 450‹ C. to cause further reaction, the catalyst then being precipitated at 225 and re-cycled. The S0 3  then reacts with water in the gas, made up to the requisite amount if necessary, at about 340‹ C., the H 2 50 4  produced then being particulated by condensing it by cooling to about 146‹ C. (the cooling may be by the dielectric plates of the third electrogasdynamic precipitator 232, which have passages for circulating cooling fluid therethrough) and the droplets being collected by electrogasdynamic precipitating.
