Title: Improvements in the manufacture and production of rubber mixtures
IPC: C08K11/00
Filed: 1934-02-19
Abstract: Rubber mixtures are made by employing as distributing agent a non-metallic non-acid product recovered or derived from an oxidation product of a non-aromatic hydrocarbon material of high molecular weight, e.g. paraffin wax.  The oxidation products, e.g. of paraffin wax, consist of acid constituents, non-acid constituents such as aldehydes, ketones, alcohols and esters, and unchanged initial material.  The non-acid constituents may be recovered by saponifying the crude oxidation products with alkalies or alkaline earths, extracting the soap solutions with solvents, e.g. benzene, and, evaporating the solvent.  Suitable non-acid products may also be obtained from the crude oxidation products of paraffin hydrocarbons by subjecting them to an energetic catalytic hydrogenation with hydrogen at elevated temperature and pressure so that the carboxylic acids, carboxylic acid esters and lactones are converted into the corresponding aldehydes or alcohols, or by esterification with alcohols e.g. methyl, ethyl, normal propyl, isopropyl or butyl alcohols.  In an example for use in a rubber mix, a non-acid product is obtained by treating paraffin wax with air at 170 DEG  C., for five hours, saponifying with alkali, extracting the soap solution with benzine and evaporating the benzine extract.ALSO:Rubber mixtures are made by employing as distributing agent a non-metallic non-acid product recovered or derived from an oxidation product of a non-aromatic hydrocarbon material of high molecular weight, e.g. paraffin wax.

Abstract: 916,819. Finishing yarns. KUNSTSEIDEN A.G. Feb. 18, 1959 [Feb. 18, 1958], No. 5635/59. Class 120 (3). In a process for the production of high-bulk yarns in which a gaseous medium flowing through a nozzle impinges on a yarn of continuous synthetic thermoplastic filaments, a hot gas or vapour, the temperature of which is in the softening and setting range of the filaments, is used as the medium and therefore acts simultaneously as both softening and setting agent. As shown in Fig. 1, a multifilament yarn 1 e.g. of nylon, is withdrawn from a bobbin 2 and fed between rollers 3 to a blowing nozzle 4 into which the hot gas, e.g. air, is introduced at 5. Yarn and gas are ejected at 6 and the yarn is abruptly removed (to relieve tension thereon) at 7 from the discharging gas jet by rollers 8 through which the yarn is fed to winding apparatus 9 driven by roller 10. The nozzle 4, Figs. 2 and 3, comprises a gas supply duct 12 opening, at 14, into a duct 11 in off-set manner so that yarn is whirled in one direction or the other by the gas stream. In another nozzle, Fig. 4, the gas passes straight through a duct 17 in member 16 and yarn 1, from a supply duct 18 opening slightly eccentrically into duct 17, is entrained by the gas stream and intensely whirled and the filaments spread thereby in a chamber 22, before ejection through an opening 20.

Title: Improvements in or relating to wheel treads
IPC: B60C11/14
Filed: 1937-02-26
Abstract: 490,950. Wheel tyres. BUDD MANUFACTURING CO., E. G. Feb. 26, 1937, No. 5854. Convention date, March 5, 1936. [Class 144 (ii)] [Also in Group V] A tread for vehicle road wheels, particularly for the treads of automobile wheel tyres, comprises rubber containing granular abrasive material which is bonded to the rubber by a material interposed between the grains and the rubber and having a higher rubber bonding quality than the grains themselves. The tread 10 has the pellets 12 so spaced that all radial lines through the rubber are interrupted by one or more of the pellets. The interposed bonding material 11 may be brass or latex. When brass is used it is melted and applied to the grains, after which the grains are separated and the brass adhering thereto solidified about the grains, the brass-enclosed grains then being introduced into the mass of rubber and vulcanized therein. When latex is used, the grains are first placed in a space from which air is evacuated, latex then being introduced into the space after which the grains are separated and the latex is solidified about the grains, e.g. by the acid or vulcanizing process. The grains with the solidified latex thereon are then introduced into the mass of rubber and vulcanized therein. If desired, the brass also may be applied to the grains while in a vacuum. The grains preferably have a specific gravity approximately equal to that of the rubber mass, and are of such hardness as to wear more slowly than the tread of the tyre but more rapidly than the material of the road surface. The grains may be conglomerated masses of sand and abrasives, or slags from aluminium, glass or carborundum furnaces.

Abstract: 924,854. Sealing-tools. SIGNODE STEEL STRAPPING CO. Feb. 22, 1960 [Feb. 24, 1959], No. 6215/60. Class 146 (2). A tool for crimping overlapped strap ends, which may be surrounded by a seal, comprises jaw members 12, 13 pivoted between side plates 10, 11 operated by a similarly pivoted handle 16 and is provided with latch means which prevent opening of the jaws unless a full crimping stroke has been made. The latch 31 is spring-urged to a position to engage a stop pin 26 to prevent links 21 being raised by the handle 16 to open the jaws 12<SP>1</SP>, 13<SP>1</SP>, but the latch may be held in a released position by a detent pawl 37 which is also urged by a spring so that its tooth 38 tends to engage a pin 36 on the latch. The arrangement is such that from the mid-position shown the jaws cannot be opened unless the crimping stroke is completed when a cam face 44 on the handle forces the latch 31 to its released position, allowing the tooth 38 to engage and hold the pin 36 so that the latch does not arrest the pin 26 as the handle is moved to its fully-open position. As this latter position is approached, the crimping jaw member 13 engages a cam 39 on the detent pawl 37 to release it from the latch which is thus freed and can engage the pin 26 until a further crimping stroke is completed.
