Title: Improvements relating to the treatment of textile fabrics
IPC: D06M15/39
Filed: 1936-11-16
Abstract: Fabrics comprising natural or regenerated cellulose are impregnated with resin-forming matter in solution, dried, the resin-forming matter converted into a water-insoluble, the fabric being subjected at any stage after the drying to a mechanical treatment adapted to break up the film of resin-forming matter on the outside of the fabric.  The mechanical treatment may consist in passing the fabric between pairs of rollers one of each pair being provided with studs and the other being resilient, or between pairs of rollers provided with relatively staggered projections; or the fabric may be drawn over a sharp edge or blade which may be moved relatively to the fabric; or the fabric may be subjected to a beating operation, or crumpled and passed between rollers repeatedly.  After such mechanical treatment the disintegrated coating is removed, e.g. by brushing or blowing. Any synthetic resin may be employed, particularly urea-formaldehyde.  In an example, a fabric of regenerated cellulose is impregnated with a solution of a urea-formaldehyde pre-condensate, dried and passed between pairs of driven wooden rollers having metallic studs, brushed and heated to 120-180 DEG  C. for 10 mins.  The mechanical treatment may be effected immediately after the drying step.

Title: Antivibratory devices with phase reversal
IPC: F16F7/108
Filed: 1970-07-01
Abstract: 1311718 Engine mountings REGIE NATIONALE DES USINES RENAULT and AUTOMOBILES PEUGEOT 1 July 1970 [25 July 1969] 31784/70 Heading B7H [Also in Division F2] A tuned mass-spring type vibration damper, shown in Fig. 1 applied to the damping of a vehicle engine 1, operates on the principle of generating compensating vibrations opposed to the driving vibrations and is effective to generate such vibrations in two orthogonal directions A, B so that all vibrations in the plane containing these directions will be annulled. The mass 5 is adjustably slidable along a bar 4 which is connected by way of spring elements 6, 7 to the vibrating structure, i.e. the engine 1, and to its support, e.g. the vehicle chassis 3. The spring elements have anisotropic elastic properties such that each possesses different stiffnesses in the two directions A and B. As shown, these springs are elastomeric sleeves rendered anisotropic by cut-outs 8: leaf springs could however be employed. In either case, the springs could be made self-damping either by the incorporation of a suitable filling in the elastomeric sleeves or by resin-coating the leaf springs. The weight 5 may also be made self-damping by employing a composite weight (Figs. 2 and 3, not shown) consisting of a core surrounded by an elastic sleeve (9) in turn surrounded by a rim (10). This would damp out high harmonic vibrations outside the range of effectiveness of the mass-spring system 5-6-7.

Title: Improvements in process and apparatus for drawing sheet glass
IPC: C03B15/08
Filed: 1921-11-30
Abstract: 192,848. White, A. E., (Pittsburgh Plate Glass Co.). Nov. 30, 1921. Drawing.-A process of drawing glass in flat sheets consists in fixing the position of the line of generation of the sheet by a guiding-device submerged in the molten glass, interrupting the flow of surface glass to the sides of the sheet by means of refractory devices projecting above the surface of the glass on each side of the sheet and applying heat to the surface of the glass between the refractory devices and the sheet. As shown in Fig. 1, the melting tank 1 has a forehearth or drawing-tank 2 which is arched over with a crown 4 and a block 5, L-shaped shielding-members 6, 7 being arranged in between the crown and the block to protect the sheet 3 as it is drawn. A refractory trough or receptacle 10, provided with a central slot 11 and side slots 12, 13 arranged and shaped as shown in Fig. 4, is placed beneath. the line of generation of the sheet. The edges 14, 15 of the receptacle extend above the surface of the glass closely adjacent to the shields 6, 7. These edges interrupt the flow of surface glass towards the sheet, and the space between the edges and the member 6, 7 permits the circulation of hot gases over the body of glass lying within the receptacle. The use of the receptacle ensuresa free flow of relatively hot glass into the sheet and the slot 11 tends to fix the line of generation of the sheet. In a modification, the receptacle may be replaced by a slotted bar of refractory material submerged in the glass, other bars serving to prevent the flow of the surface glass intothe sheet. In a further modification, shown in Fig. 10, a watercooled tube 40, or a refractory bar having a V-shaped upper edge, is submerged in the glass and tends to fix the line of generation of the sheet. Prevention of narrowing.-In order to counteract the tendency of the sheet to draw in at the edges, a rod 31, Fig. 6, curved at its end 32, is used to form depressions 33, Figs. 6 and 7, in the glass on either side of the edges of the sheet. These depressions are made at intervals during the drawing, and the consequent cooling of the glass makes it stiffer near the edges of the sheet.

Title: Improvements in and relating to synthetic resins
IPC: C08G63/46
Filed: 1927-11-30
Abstract: 306,924. Grindley & Co., Ltd., and Yeates, R. L. Nov. 30, 1927. Ester condensation and polymerization products.-Resinous bodies are prepared by bringing together a polyhydric alcohol, a polybasic acid or its anhydride, and an acid resin and/or a fatty acid, such as oleic or stearic acid, derived from a non-drying oil or from a fat, and bringing the mixture to a suitable temperature for reaction; the mixture may include also fatty acids derived from drying oils such as linseed or chinawood oil. Acid resins specified as suitable for use comprise colophony, liquid rosin obtained for instance in the production of wood pulp, rosin oils of acid character, and abietic acid. Products of low acid value may be obtained by causing substantially the whole acidic content of the mixture to combine with the polyhydric alcohol, or alternatively by including in the mixture the oxides, hydroxides, or suitable salts of polyvalent metals such as aluminium, calcium, or zinc. The products are soluble in solvents of the kind used in preparing cellulose lacquers, and may be used in conjunction with plasticizers for cellulose esters such as, inter alia, ethyl, amyl, or butyl stearate and tartrate and cyclohexanyl phthalate and oxalate. In an example, glycerol, phthalic anhydride, and French rosin are heated together at 200-210‹ C. for about three hours and then at 260-270‹ for a similar period, a soluble product of low acid value being obtained. Specification 284,349 is referred to.
