Abstract: 380,438. Discharge apparatus. M-O VALVE CO., Ltd., Marconi House, Strand, London, EDEN, C. G. and SMITHELLS, C. J., of General Electric Co., Wembley, Middlesex. June 1, 1931, No. 15997. [Class 39 (i).] A method of making a rigid insulating connection between metallic members such as the electrodes or electrode supports of a thermionic valve or other electric discharge device comprises providing each metallic member with a hole, passing an elongated vitreous body through each hole and expanding laterally the portions of the vitreous body between the metallic members. In the example the electrode supports consist of a series of metal strips 1 arranged parallel to one another, with holes 2 arranged in axial alignment to receive a glass rod 4 of cross-section corresponding to that of the holes 2. To secure the strips to the glass rod the ends of the strips are located in spaced slots 3 in a supporting member and the rod 4 is heated until it is softened, whereupon pressure is applied upon its ends by jaws 5, the final form of the rod 4 and position of the jaws being indicated in broken line. In a modification a glass tube is substituted for the rod and expanded laterally by blowing air into its open ends, after heating to soften it. The electrode supports may consist of wires which are looped to receive the vitreous supporting member.

Abstract: 1,262,823. Elastically stretchable leather like material; textile treating apparatus. R. T. DAWES. 7 April, 1970, No. 16333/70. Headings D1L and D1P. A method of preparing an elastically stretchable artificial leather comprises (i) providing as a base fabric a woven, one-way stretch elastic web comprising warp and weft yarns of textile material and wherein bare rubber-threads are interspersed between the warp yarns, the rubber elastic threads being located at the midplane of the fabric and the average weight of the base fabric being 0.0514- 0.0529 pounds for a yard-long strip, one inch wide and its max. elongation being 110- 120% (ii) providing, as an impregnant, a latex of a thermoplastic synthetic resin e.g. acrylic and vinyl polymers to which solids have been added such that total solids in the impregnant are 18.3-18.75% of the total weight, the viscosity being 16-23 sec. No. 4. Ford Cup, immersing the base fabric while slack in the impregnating liquid at ambient temp. and atmospheric pressure for 5-6 sec. whereby the textile yarns individually absorb impregnant, but without closing the interstices between the yarns, to the extent that the weight of the material, after drying exceeds that of the unimpregnated base material by 0.00235 pounds in a yard long strip, one-inch wide. After drying, the material is embossed at least on one side at from 250‹ to 270‹F and pressure of 900-1000 p.s.i. As an alternative procedure before the material is embossed, there is applied to one surface of the dried material a uniform coating of the impregnant substance such as to add 2-3% additional weight to the impregnated and dried material. The coated material is then advanced through a space heated to 200‹F at a rate of 10 yards per minute and then the coated surface is embossed. The textile yarns and rubber threads may all be of approximately the same size and the impregnant liquid preferably comprises an acrylonitrile-butadiene copolymer and after embossing the surface may be sprayed with a finishing lacquer. As shown, the apparatus comprises a roll 10 of base fabric which passes down through a vat or tank 12 containing a body 12a of the impregnating material, the fabric then passes beneath the guide rolls 13 and 14 and then up out of the tank and between squeeze rolls 15 and then passed over drying cans or drums 16. The dried fabric is impregnated on one side and then conducted about guide rolls 17 and 18 and beneath a container 19 which delivers by a doctor blade the film onto the advancing web then the web is passed through a preheating chamber 20 and finally through a pair of rolls 21 and 22.

Abstract: 1,011,744. Laminates and laminating. BOEING CO. April 30, 1962, No. 16462/62. Heading B5N. Laminates comprising thermoplastic material, such as P.V.C., cellulose acetate-butyrate or polythene, sandwiched between layers of " bleeder " material, are made by hot pressing under vacuum which removes trapped air and gaseous decomposition products through the bleeder material, at least one layer of bleeder material being fused to the thermoplastic layer as a component of the product. As shown, Fig. 1, a vacuum press of the flexible membrane type comprising a base 10 and a membrane 12 encloses an assembly comprising coarse cloth 14, a porous aluminium plate 16 made by flame spraying the metal, a layer F of P.V.C., a decorative porous layer C of unwoven fibres, paper, or a composite layer of cloth and decorative foil, film or scattered fibres, a P.V.C. layer B, a parting film 18 of polyvinyl alcohol, and a layer 20 of coarse cloth. The base 10 comprises hollow conduits for heating, e.g. by steam, and cooling. The assembly is vacuum compressed by the membrane and is heated in two stages and finally rapidly cooled. During the operation vapours &c. are removed via the layers 14, 16 and 20, the parting layer 18 which wrinkles under heat and pressure, and the layer C which projects beyond the other layers to prevent clogging with P.V.C. and which forms part of the product. Layer F is preferably transparent and may carry decoration in the form of printing on its inner face; it is patterned by layer 16. Layer B may be opaque, e.g. white. Alternatively the assembly FCB may be inverted and the layer 18 replaced by nylon gauze which becomes fused into layer F, this layer also being patterned by the cloth layer 20. Apparatus for carrying out the invention is described herein and is claimed in Specifications 1,011,745 and 1,011,746. Lightweight wall structures may be formed by providing the products of the invention with honeycomb backings.

[Also in Group XXIV] To improve the wearing surfaces of flat, multi-groove or V driving or conveyer belts having rubber or rubber impregnated fabric surfaces, fibre-flock is randomly deposited on an adhesive cement applied to the belt surface prior to vulcanizing, so that during vulcanizing the fibres become embedded in the rubber. As applied to a multi-groove belt the fibre-flock is applied to a flat surface to be grooved in the vulcanizing press, the pressing then re-orientates the fibres so that more than half lie transversely of the belt, thus increasing the lateral stiffness and decreasing the longitudinal stiffness of the belt.
