Title: Internal shoe-drum brakes
IPC: F16D65/46
Filed: 1964-08-04
Abstract: 1,057,307. Internal shoe-drum brakes; brake cylinders. EATON GALE & TOWNER Inc. Aug. 4, 1964 [Sept. 12. 1963], No. 30766/64. Headings F2E and F2F. In an internal shoe drum brake the brake shoes 13 (only one shown) are adapted to be moved into engagement with the brake drum (not shown) by means of two wedge (29) and a roller (62, 63) devices 11, so that lengthwise movement of the wedge member 29 under the influence of fluid pressure in a chamber behind an annular piston 78 causes movement of actuating elements in the form of plunders 32, 33 to actuate the brake shoes, wherein the tapered surfaces on the wedge member 29 and the plungers 32, 33 are curved in the lengthwise direction. The annular piston 78 is provided with a rolling diaphragm 90 adapted to be actuated by means of fluid pressure. Alternatively, the wedge may be actuated by an annular piston operated directly by fluid pressure or alternatively by individual motor means in the form of flexible diaphragm chambers. Another embodiment (Fig. 12, not shown), the wedge member is operated by a pull rod or cable. As shown in Fig. 4, the wedge member 29 is adapted to be received in a groove 80 in the annular piston 78 and coupled to the annular piston 78 through pin-and-slot connections 86 to 89 inclusive so that the wedge member can move in a direction transverse to its longitudinal axis in response to forces applied to the tapered extremity during actuation of the brake. Resilient abutment pads 82 may be provided between the base of the groove 80 and the underside 81 of the wedge member 29. Provision is made for manual adjustment to take account of brake lining wear and this takes the form of a threaded adjustment stud 41 extending into the plunger 32 and adapted to be rotated by means of a worm-wheel 45 when the latter is driven by a worm 47 (Fig. 5, not shown) which is adapted to be rotated by means of a tool engageable with the outer extremity of the shank 50. A dust shield 103 is provided to protect the brake assembly against the ingress of dirt (Fig. 2, not shown).

Title: Improvements relating to processes for separating and recovering the rubber and fibre constituents of unvulcanised rubber scrap containing fibrous material incorporated in it
IPC: C08J11/16
Filed: 1939-11-25
Abstract: 533,769. Recovering materials from coated fabrics. SOC. ITALIANA PIRELLI. Nov. 25, 1939, No. 30777. Convention date, Dec. 12, 1938. [Class 140] In a mechanical process for separating and recovering rubber and fibre from unvulcanized rubber-fibre scrap, it is preliminarily subjected to a chemical treatment, e.g. by an aqueous solution of caustic alkali, or alkali sulphide or carbonate or ammonia to swell the fibres. The treatment is controlled so that the structure of the fibres is not destroyed. In the example the rubber scrap is treated for eight hours at 80‹C. with a 3-4 per cent. aqueous solution of caustic potash containing 20 per cent. of sodium sulphide. The disintegration of the rubber and fibres is effected in a paper-type beater in the presence of water at 50-60‹C. after which the mass is treated in a vessel fitted with revolving spoked wheels. Separation of the fibre is effected in settling tanks or by passing through grates and screens (paper purifiers and sorters). An oil or adhesive substance, e.g. mineral oil, tar pitch oil or colophony may be added to the scrap to assist in settling the rubber.

Abstract: 444,913. Conductors. BOEHRINGER & SOEHNE GES., C. F., Waldhof, Mannheim, Germanv. Oct. 29, 1934, No. 31026. Convention date, Nov. 18, 1933. [Class 36] In a process for the manufacture of a conductor insulated by a lapping of artificial silk threads, the threads or bundles of threads are moistened, impregnated, or coated with hydrocarbons in a quantity sufficient to prevent electrification of the threads during the lapping operation but not sufficient to prevent the capillaries of the threads from running on to the conductor in ribbon form. Suitable hydrocarbons are high-boiling benzine, paraffin oil, paraffin wax and xylene, and these may be applied by dipping, spraying, or by passing the threads through a bath containing the hydrocarbon, or by drawing the threads across felt layers soaked with the hydrocarbon. Solid hydrocarbons may be applied by smearing the threads, or by drawing them lightly against the hydrocarbon, or the hydrocarbon may be dissolved in a solvent, preferably a hydrocarbon solvent, and applied as a solution.

Title: Improvements in or relating to the manufacture of aerated beverages
IPC: A23L2/40
Filed: 1933-11-08
Abstract: In the manufacture of carbonated beverages pectin is added in order to increase the power of the liquid for retaining carbon dioxide in solution.  The pectin is preferably added before the addition of the carbon dioxide and to a beverage which contains practically no nitrates in solution.  When the beverages do not contain appreciable amounts of sugar, the effect of the pectin may be improved by adding lecithin also.  Examples are given, showing the application of the invention to aerated distilled water, mineral water, and beer.

Title: A method of manufacture of an aluminium alloy and the alloy obtained by this process
IPC: C22C1/04
Filed: 1958-10-01
Abstract: An alloy of aluminium and 0.05-4.0% of iron or nickel or both, having improved resistance to corrosion by water at high temperatures, is produced by forming alloyed granules of p  aluminium and added metal in the required proportions, compressing to form a mass and extruding to produce a shearing effect in at least the portion of the mass adjacent the surface. The granules may be formed by atomizing the liquid alloy or by coating aluminium granules with the added metal, chemically or mechanically, or with a compound of the metal capable of being reduced by aluminium.  After reduction, if necessary, the coated granules are heat treated to ensure diffusion of the coating metal and aluminium.  Preferably the granules contain as impurities silicon less than 0.01%, zinc, manganese, and magnesium less than 0.005% each, and copper less than 0.01%.  In examples given the granules are compressed cold at pressures of 40 or 100 kg/mm2, heated to 600 DEG C. or 620 DEG C. and extruded at 500 DEG C. or 600 DEG C. Preferably additional shearing is caused during extrusion by arranging deviations or constrictions in the vicinity of the extrusion orifice.
