Abstract: 1,149,307. Current collector-terminal strip assemblies for electric cells. GENERAL ELECTRIC CO. 7 April, 1967 [8 April, 1966], No. 16036/67. Heading H1B. The current collector 1 of an electrode assembly is a conductive sheet 5 folded to form a plurality of troughs 7 opening from one face forming a plurality of projections on the opposite face and has a compacted powder electrode interlocking with the projections and a terminal strip 3 fitted into at least the trough of a fold. A compacted powder electrode is formed on the current collector 1 with the terminal strip 3 folded in as shown in Fig. 1.

Patent GB-778435-A (GB)
Title: Continuous process for the hydrolysis of organo-silanes
IPC: C08G77/00
Filed: 1955-06-03
Abstract: <PICT:0778435/IV(a)/1> In the continuous hydrolysis of organosilanes in the liquid phase, slightly alkaline water is contacted with a solution of hydrolysable organosilanes in an organic solvent which is imiscible or partially miscible with water and aqueous acids but readily miscible with the silanes and the hydrolysates thereof to give a solution of different density from that of the alkaline water, the two liquids being supplied to opposite ends of a vertically elongated zone of sufficient height to permit complete hydrolysis during the passage of the liquids therethrough, the heavier reactant being supplied to the upper part of the zone and a substantially neutral siloxane solution being withdrawn from the opposite end of the zone to which the silane mixture is supplied. The silanes used are organohalogenosilanes having the R:Si ratio at most equal to 2.1:1 and are generally mixtures of organochlorosilanes which may contain alkoxysilanes.  The silane solution may be fed to the top or bottom of the reaction zone according to whether it is lighter or more dense than the aqueous phase resulting from the hydrolysis.  In Example (1), a diethyl ether solution of methyltrichloro- and dimethyldichloro-silanes (R:Si=1.3: 1) is continuously introduced at b into the lower part of a glass column h, packed with Raschig rings and filled with aqueous hydrochloric acid saturated with ether; and a 0.01 per cent aqueous ammonia solution is introduced at a; a neutral siloxane emerges at c and an ethereal aqueous HCl solution issues from d.  Entrained siloxane may be recovered by solvent extraction from the latter solution prior to recovery by distillation of ether and HCl.  The column h may be cooled, e.g. by means of an outer jacket or an internal cluster of heat exchange tubes.  When the silane solution is the lighter reactant, a part of the reaction mixture may be recycled through a cooler f and returned to the point of entry of the silane solution; other examples disclose the hydrolysis of (2) a trichloroethylene solution of dimethyldichloro-, phenyltrichloro- and diphenyldichloro-silanes; (3) an ethereal solution of methylchlorosilanes (R:Si=1.5: 1) obtained by distillation at 148 DEG  to 150 DEG  C. of the crude product of the reaction of CH3Cl with Si; (4) an ethereal solution of dimethyldichloro-, methyltrichloro- and phenyltrichloro-silanes (R:Si=1.3: 1); (5) an ethereal solution of trimethylchloro-, dimethyldichloro- and methyltrichloro-silanes (R:Si=1.5: 1); (6) a petroleum spirit solution of dimethyldichlorosilane; and (7) a trichloroethylene solution of methylhydrogendichloro- and dimethyldichloro-silanes.

Abstract: 787,277. Flexible laminates. HAWLEY PRODUCTS, CO. June 6, 1955 [Sept. 1, 1954], No. 16126/55. Drawings to Specification. Class 140. A reinforced laminated sheet material is produced by providing a porous surface on one side only of a sheet of synthetic resin of sufficient flexibility to be wound into a roll and permanently uniting to said porous surface substantially rigid elongated reinforcing members in parallel relation at intervals sufficient to allow the laminated sheet material to be wound into a roll. Preferably the outer smooth surface of the laminated material is of hard polyvinyl chloride or hard polyvinylidene chloride and the porous surface is provided by paper adhesively bonded to it by polyvinyl acetate or ureaformaldehyde adhesive, wooden bars being adhesively bonded as reinforcing members. Instead of a single layer of synthetic resin several layers may be laminated together, and a decorative effect may be obtained by sandwiching between them a decorative woven cloth, glass fibres, paper bearing a coloured or printed design, leaves, &c., through which the synthetic resins penetrate. Other suitable synthetic resins are copolymers of vinyl chloride with vinyl chloride or vinylidene chloride, or polyester resins, and the porous sheet may be corrugated. The layers may be united by means of the press described in Specification 760,071.

Abstract: 689,724. Tanning agents. BOHME FETTCHEMIE GES. July 9, 1951. [Aug. 14, 1950] No. 16184/51. Class 76. A tanning oil which is stable in the presence of salts and chromium compounds comprises a sulphonated oil mixed with a water-soluble polyalkylene oxide derivative, derived from polyalkylene oxide waxes of molecular weight at least 2,000 and having at least one aliphatic, alicyclic, aromatic, aliphatic-alicyclic, alicyclicaromatic, or aliphatic-aromatic radical united with the polyalkylene oxide wax through oxygen, sulphur, or nitrogen. A suitable derivative is a polyethylene oxide wax ester obtained from polyethylene oxide waxes of molecular weight 2,000-9,000 and natural or synthetic fatty acids with at least 4 carbon atoms in the molecule ; other starting materials mentioned are butyl alcohol, octyl alcohol, octyl mercaptan, dodeclyamine, cyclohexanol, cyclohexylamine, naphthols, benzyl alcohol, ar-tetralol, naphthenic acids, oleic acid, lauric acid amide, and alkylbenzene sulphonic acid amides. The additive may amount to 10-50 per cent of the tanning oil. Suitable sulphonated oils are Turkey-red oil, sulphonated neatsfoot, sperm, train, poppy, and sunflower oils, and the sulphonates of natural and synthetic hydrocarbon oils. In an example, an oil consisting of Turkey-red oil, spindle oil, and oleyl alcohol sulphonate is mixed with a partial ester obtained from polyethylene oxide wax and acids resulting from the oxidation of paraffins; the mixture may be combined with solutions of common salt and chrome alum and used in the production of soft leather by the "brush" process.

Abstract: 1,222,806. Shock absorber valve. A. A. DE KONING, and K. K. K. DE KONING. 27 March, 1969 [11 April, 1968], No. 16222/69. Heading F2S. A valve element 25, Fig. 2, movable to throttle flow of hydraulic fluid between a clyinder 6 and a reservoir 14 of a shock absorber, Fig. 1, is indirectly responsive to changes in pressure of another fluid supplied, at 35, from outside the shock absorber. This fluid (e.g. from a pneumatic spring to which the shock absorber is coupled) acts on a control member 33 which in turn acts on the valve element 25. The position of the latter may also be made dependent on the pressure of the damping fluid occurring in the shock absorber, in the usual way. The control member 33 is a body of revolution and its surface which acts on the valve element is inclined at an acute angle both to the direction of movement of the control member and to the direction of movement of the valve element. Thus, when the control member is displaced, the point of intersection of the generating line of the control member and the centre line of the valve element in the direction of movement of the valve element is displaced along the centre line.

A filamentary reinforcing material is made by subjecting a filamentary material having a Young's modulus of at least 700 kg./mm.<SP>2</SP> and obtained from polyethylene terephthalate or an aromatic polyamide to heat treatment while allowing it to contract. Heat treatment may be carried out in an inert heated fluid, e.g. water, steam, liquid paraffin, silicone oil or a molten metal or in a heated inert gas e.g. air or nitrogen, or by contacting the material with a heated metal plate, and may be effected at any stage during the manufacture of cords or cord fabric from yarns, but generally in a separate heat-treatment or during a combined adhesionheat treatment of the cord. Cords may be treated at from 100‹ C. to the melting-point of the filamentary material, but preferably at temperatures of at least 150‹ C. Yarns may be treated at 90-180‹ C. for from 0.5 sec. to 5 mins. and the heat-treated polyethylene terephthalate yarn wound up at a speed slower than the feeding speed of the yarn to the heating zone. Polyethylene terephthalate filamentary material used is preferably obtained from chip having an intrinsic viscosity of at least 0.71, as determined in ortho-chlorophenol at 35‹ C., which has been welt spun and drawn.
