Title: Improvements relating to methods of applying a single coating of insulating materialor like plastic material to a plurality of electrical conductors or like wires or strands by extrusion, followed by a vulcanising or similar hardening process
IPC: B29C48/156
Filed: 1930-08-18
Abstract: 361,326. Covering wires &c. by extrusion-machines; vulcanizing. W E S T E R N ELECTRIC CO., Ltd., Bush House, Aldwych, London.- ( Bell Telephone Laboratories, Inc. ; 463, West Street, New York, U.S.A.) Aug. 18, 1930, No. 24703. [Classes 70 and 87 (ii).] In apparatus for covering two or more wires by extrusion with a common coating of rubber or like insulating material and then vulcanizing it, special provision is made for taking up a new reel of wire whenever a reel is exhausted, without stoppage of the machine. The wires are arranged in staggered relation so that when one becomes exhausted, the remainder are continuous through the extrusion apparatus. The continuous wire or wires, aided by the coating, in some instances serves to bind the end of the new wire sufficiently to carry it through the apparatus, but a guiding thread of limp material may also be used as hereinafter described. As applied to a twin-wire conductor, wires from the reels 13, 15 are passed through the extrusion apparatus 9 and vulcanizing apparatus 16 in turn and then round a capstan 19 to the storage reel 20. A spare reel 14 is provided from which the wire is fed into the extrusion apparatus to follow the used-up wire. To prevent the new wire springing in the soft coating and so fouling the seal at the exit end of the vulcanizing apparatus, a short length of wire 34, Fig. 2, of less rigidity than the main supply is secured to its forward end to become embedded in the partly-hardened vulcanized coating before the end of the main wire enters the extrusion apparatus. This wire of less rigidity may in some instances also be attached to the rear end 30 of the used-up wire. The seal comprises a number of rubber or other discs 22 contacting with the wire and held against the end of the chamber by a member 25 mounted in a screw cap 21 and pressed. inwardly by a bell crank 26 actuated by compressed air. The gap in continuity of the wire in the finished product is indicated by relative limpness at that point and thus is readily ascertainable for cutting and splicing.

Title: Process for the hydrofluorination of halogenated ethylenes
IPC: C07C17/087
Filed: 1950-10-10
Abstract: Halogenated ethylenes are hydrofluorinated by heating a dry halogenated ethylene with hydrogen fluoride containing more hydrogen fluoride than the commercial anhydrous hydrogen fluoride, namely a hydrogen fluoride containing 99.8 to 100 per cent HF, to reaction temperatures in the presence of one part or less per thousand of a hydrofluorination catalyst.  The use of such anhydrous HF permits the use of much less catalyst and results in higher yields of halo-alkanes than when commercially anhydrous HF is used.  In an example, dry trichlorethylene and anhydrous hydrogen fluoride containing 99.9-100 per cent HF are heated with an amount of a solution of BF3 in methanol as catalyst at 150 DEG  C. for 24 hours in a sealed iron cylinder having a fractionating column and 1 : 1 - dichloro - 1 - fluoro - 2 - chloroethane is obtained.  Other catalysts mentioned are titanium tetrachloride, antimony pentachloride, ferric chloride and aluminium chloride.  Specification 627,773 is referred to.

IPC: C25D1/22
Filed: 1948-09-24
Abstract: 651,611. Electrodeposition of metals. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Sept. 24, 1948, No. 24977. [Class 41] A method of making metal articles by electrodeposition comprises electrodeposition on an electrode provided with a thin film of albumen, dextrin, gelatine, glue or gum arabic, whereby subsequent separation of the article from the electrode is facilitated. The method may be applied to the manufacture of a gramophone record, a master matrix being provided with the film, and metal being electrodeposited thereon to form a pressing matrix, which is removed from the master matrix and serves for the production of the records. As an example of the process, an adsorbed film is made on a master matrix by immersion in a medium consisting of egg albumen, a wetting agent and water. After immersion the matrix is rinsed in running water and metal is then deposited on it. Another method of forming the film is by electrophoresis.

Abstract: 673,112. Coke ovens. WOODALL-DUCKHAM VERTICAL RETORT & OVEN CONSTRUCTION CO. (1920), Ltd.,.and TAYLOR, A. Sept. 27, 1950 [Sept. 30, 1949], No: 25193/49. Class 51 (ii). In a compound indirectly heated retort or oven, particularly a compound coke oven battery of the CoppÚe type, even distribution of heat in the heating flues when fired either by rich gas, e.g. coke oven gas or by poor gas, e.g. blast furnace gas is enhanced by, in each heating flue, constructing or surfacing the wall remote from the burner with a material having a heat absorption capacity greater than that of the material used for the heating flue wall near to the burner when a luminous flame or rich gas flame is used. A suitable combination is obtained by constructing or surfacing the remote sections of the flues of chrome magnesite or surfacing them with Siemens-Martin slag and constructing the sections near the burners of silica. Using the chrome magnesite-silica combination, the ratio between the wall areas is 1 : 1 and between the wall thicknesses 4 : 5 respectively. Alternatively, the remote sections of each flue may be made of silica and the sections near the burner of a substance having opposite absorption characteristics with respect to both luminous and non-luminous flames to those of chrome magnesite and Siemens- Martin slag.

Title: Improvements in or relating to the manufacture of titanium pigments
IPC: C09C1/36
Filed: 1937-09-18
Abstract: Calcined titanium pigments are separated into particles of different sizes by dispersing them in water with the aid of a solution of a basic chloride of aluminium, cerium, iron thallium, thorium, titanium, or zirconium, with or without grinding, allowing the coarser particles to settle, and separating the aqueous suspension of the dispersed fine particles. Alternatively, the coarse particles may be separated in a centrifuge.  From 0,1 to 2,5 parts of dispersing agent, reckoned as oxide, may be used for every 100 parts of pigment. The fine particles in suspension may be coagulated, as by addition of ammonia to give a pH value of 7 to the dispersion, or by addition of alkali or alkaline-earth metal hydroxides or of magnesium sulphate, and the pigment be then separated by settling and filtration.  In examples, solutions of aluminium chloride of 60 per cent basicity and of titanium chloride of 70 per cent basicity are used as dispersing agents.  Such solutions may be obtained by dissolving the hydroxide or basic sulphate in a deficiency of hydrochloric acid.  The presence of soluble sulphates should be avoided, and this may be ensured by precipitating the SO4 ion by barium chloride.  Specification 440,611 is referred to.
