Title: Actuator assembly for vehicle brakes
IPC: F16D65/14
Filed: 1974-06-18
Abstract: 1513245 Actuators for internal shoe-drum brakes GIRLING LTD 18 June 1975 [18 June 1974] 26852/74 Heading F2E An actuator assembly for a shoe-drum brake comprises a wedge member 18 acting through rollers 11, retained in a cage 12, on inclined surfaces 9, 10 of plungers 3, 4 to move them outwardly of a housing 1 in opposite directions, the cage assembly 11, 12 and the wedge member 18 being inserted separately into the housing 1 through apertures 27, 31 respectively which ensure their correct orientation therein. As shown, the cage 11 has a mushroomshaped head 16 with an apertive 17 through which passes wedge member 18, the head 16 engaging plungers 3, 4 at their maximum separation to prevent rollers 11 from becoming displaced from between surfaces 9, 10. The aperture 27 which is formed in housing 1 is of width A to ensure correct orientation of the cage assembly 11, 12 when it is inserted into the housing 1 before a cover 28 is fixed in position. Plunger 3 is formed with two parallel projections 13 defining a slot for guiding the cage assembly 11, 12. The wedge member 18 which is part of a wedge assembly 6 comprising an integral push rod 19 and a compression spring 20 has parallel side walls 25 and inclined walls 26 for engagement with the rollers 11. The aperture 31 which is of generally oblong form is formed in an abutment washer 29 seated against a step 30 in a bore 5 in the housing 1. The washer 29 has a resilient tag 32 received in a groove 35 to key the washer 29 against rotation. If an attempt is made to insert wedge member 18 into bore 5 when it is misorientated the inclined walls 26 of the wedge member 18 will come into engagement with arms 33 on the washer 29 to prevent further movement of the wedge member 18. The outer end of the push rod 19 then projects sufficiently far from the housing 1 to prevent an air chamber from being assembled to the housing 1 for actuation of the wedge member. In a further construction the cage assembly is inserted into the housing through an aperture in which one of the plungers normally works, the aperture being shaped to prevent misorientation of the cage assembly.

Abstract: 1276271 Polymers containing polymerized emulsifying agents STANDARD BRANDS CHEMICAL INDUSTRIES Inc 4 June 1970 [26 June 1969] 27085/70 Headings C3P C3Q and C3R A copolymer is made by the acid aqueous emulsion polymerization of a mixture of 20- 55% by weight of methacrylic acid, part of which may be replaced by another carboxylic monomer, 3-35% by weight of an ester of an ethylenically unsaturated polycarboxylic acid anhydride and a polyoxyethylated alcohol or phenol, and at least 35% by weight of styrene and/or butadiene, optionally with a minor amount of a further monomer. The esters exemplified are of maleic anhydride and polyoxyethylated alkyl phenols. A dispersion or solution of the polymer may be added to a latex, e.g. of natural rubber, neoprene, carboxylic latex, SBR, or acrylic polymer, and the pH is made alkaline so as to cause in situ thickening of the latex. The emulsion may also be used as a dispersing agent in a printing paste or ink comprising pigment, solvent, surfactant, and butylated melamine-formaldehyde resin or carboxylated nitrile rubber. Esters of alkyl and dialkyl phenoxy polyethyleneoxy ethanols and maleic anhydride are prepared by heating the reactants in bulk in the presence of a polymerization inhibitor.

Title: Improvements in or relating to plain bearings
Inventor: TAIT WILLIAM HENRY
IPC: F16C33/12
Filed: 1952-11-03
Abstract: 711,438. Plain bearings. GLACIER METAL CO., Ltd. Nov. 3, 1952 [Nov. 23, 1951], No. 27533/51. Class 12(1) A plain bearing comprises a metal backing, a cushioning layer of lead, a bearing facing of a soft tin containing alloy, e.g. a tin or lead base alloy, and between the cushioning layer and the facing, a thin barrier layer of a metal such as nickel, cobalt or iron which is resistant to tin diffusion. In one embodiment the backing 1 is of steel 0.035 inch to 0.250 inch in thickness on to which a 70: 30 copper-lead layer 2 of 0.010 inch to 0.080 inch thickness is sintered. The liner is then lead plated in the bore, layer 3, to 0.0005 inch to 0.004 inch thickness, the lead coating being burnished to eliminate porosity, then cleaned, and nickel plated 4 to a thickness of 0.00005 inch to 0.00015 inch to form the tin barrier. A tin-lead alloy containing 10 per cent tin is then deposited to a thickness of 0.0005 inch to 0.005 inch and bored to give a final bearing surface. In a further embodiment the bearing comprises a backing of copper alloy, e.g. 80:20 copper zinc, a thin cushion layer of lead .of 0.0005 inch to 0.004 inch thickness electrodeposited thereon, followed by a thin layer of nickel and a bearing facing of tin-lead as before described. The bearings of this embodiment are suitable for use in aluminium housings as their co-efficient of thermal expansion is nearer to that of aluminium than a steel backed bearing. Various moduli of elasticity are given for the layer materials so that a bearing may be made which can yield elastically to accommodate slight' transient misalignments.
