Abstract: 924,301. Double-faced pile fabric; laminates. GREFRATH VELOUR G.m.b.H. Aug. 22, 1960 [Feb. 18, 1960], No. 28943/60. Class 74 (2). A double-faced pile fabric has the pile on one surface consisting of the free ends of the pile warp of the woven or knitted fabric and the pile on the other surface consisting of applied short fibre pieces which are shorter than the free pile ends and are adhered to the fabric by means of an adhesive. The adhesive may be in the form of a water- and solvent-resisting layer, disposed between the short fibre pieces forming one pile and the woven or knitted fabric. The short fibre pieces forming one pile may be normal to the surface of the woven or knitted fabric. The pile surface covered with short fibre pieces may be smoothed by removal of any protruding irregularities, e.g. by grinding, and is made water-repellent by treatment with silicones. At least one intermediate layer may be provided between the woven or knitted base fabrics forming the pile thread ends and the adhesive layer bonding the short fibre pieces. A material which consists of or contains textile bound, i.e. woven or knitted, threads may be provided to form at least one intermediate layer. At least one intermediate layer may be formed by a non-woven material which consists of or contains fibre materials, held together by an adhesive, or by a material which consists of a foil. The intermediate layer may be of polyvinyl chloride, polyester, polyvinyl butyral or polyamide. The intermediate layer may be adhered to the woven or knitted base fabric and then flocked, or the intermediate layer may be flocked first and then adhered to the base fabric. The pile fabric may be figured or styled, e.g. one or both piles may be printed upon or the short fibre pieces or the pile warps may be predried. The short fibrepieces may be of cotton, wool, viscose, cellulose or of other synthetic material, e.g. linear polyamide. Material for the pile warps may consist of wool, rayon or synthetic material. The adhesive may be based on polyesterpolyisocyanate or plasticized polyvinyl chloride compositions, and may contain an expanding agent, e.g. carbon dioxide, ammonium bicarbonate, benzene sulphonic acid, diphenylsulphur-3, and 3<SP>1</SP>-disulphohydrazide.

Abstract: 977,558. Book-keeping. GEORGE ANSON & CO. Ltd. July 26, 1963 [July 27, 1962], No. 29007/62. Heading B6A. A manifolding apparatus comprises a baseboard 1, Fig. 1, supporting a rack 2 for mounting of a copy sheet, a holder 5 mounted slidably on a bar 6 for location of an employee's record sheet and a magazine holder 15 fixed to the apparatus and carrying a first stop member 26, Fig. 2, co-operating with a second stop member 25 articulated to a magazine platform 12 carrying copy slips, on which records made on the record sheets are copied and means including a handle 3 for longitudinal displacement of the magazine platform in the holder 15 until the stop members engage whereupon pivotal means including levers 21 become operative to lower the platform 12 for extraction of the uppermost copy slip. In operation a copy sheet is located by a pair of pins (not shown) on the rack 2. An employee's record sheet is superposed on the copy sheet and located by a pair of pins (not shown) in the holder 5 which is advanced to the appropriate week, indicated by a number viewable through an aperture 8 in a disc 5a, and locked in position by a pin on the underside of the disc engaging in a selected one of a set of apertures 7. Subsequently details of an employee's wages are entered on the record sheet and reproduced on the copy sheet and copy slip which are interleaved with transfer material. To facilitate the removal of the uppermost copy slip from the magazine 10 the handle 3 is depressed whereupon the magazine 10 and the platform 12 are displaced longitudinally by associated linkage 20, 19, 18 acting on a peg 16 attached to the magazine 10. The magazine and the platform are arrested when the stop member 25, on a bar 24 attached pivotally through levers 21 to the platform 12, engages a fixed stop member 26. Further displacement of the peg 16 by the link 18 pivots the levers 21 against the action of spring 27, Fig. 5, so that continued movement of the magazine 10 brings about levering of the platform 12, which releases its clamping forces on the copy slips whereby the uppermost slip may be removed. Simultaneously with the depression of the handle 3 the rack 2 is moved one step forward. On release of the handle 3 a spring 29 returns the magazine to its original position and the spring 27 pivots the levers 21 back to raise the platform into renewed engagement with flanges 11 of the magazine 10. Specifications 571,620, 597,519 and 735,484 are referred to.

Title: Improvements in or relating to the production of low permeability carbon
Inventor: RIVINGTON HERBERT LAWRENCE
IPC: C04B35/524
Filed: 1959-08-28
Abstract: Low permeability carbon, i.e. carbon of permeability such that the volume of helium which can pass through one centimetre cube of the carbon in one second under a pressure difference of one atmosphere is not greater than 10-6ml., is produced by heating a polymer which has been formed from a polymerizable monomeric cyclic carbon-containing compound at a sufficiently high temperature and for a sufficient length of time to cause the polymer to decompose completely into carbon and volatile matter and to drive off the volatile matter. Suitable polymers are those produced from furfuryl alcohol, furfural, furane, coumarone, indene, cyclopentadiene and mixtures thereof. Shaped carbon bodies of low permeability may be produced by polymerizing or partly polymerizing a polymerizable monomeric cyclic carbon-containing compound or mixture of such compounds under heat and pressure, arresting the polymerization process when the material is sufficiently plastic to mould, moulding the material to the desired shape, completing the polymerization process if necessary, and heating the polymerized material at a sufficiently high temperature and for a sufficient length of time to cause it to decompose completely into carbon and volatile matter and to drive off the volatile matter.
