Title: Vehicular brakes
IPC: F16D65/56
Filed: 1971-07-14
Abstract: 1353673 Spot-type disc brakes; fluid and mechanical actuation and release KELSEYHAYES CO 14 July 1971 [21 July 1970] 33072/71 Heading F2E A spot-type disc brake assembly comprises a housing 19 having a bore 22 accommodating a fluid-operated piston 18 which applies a pad 15 to a rotor 12, biasing means (as shown, Belleville springs 46) connected with the piston so as to exert an actuating force on it when required, and release means such as an auxiliary piston 51 and a nut 74 for separately relieving the piston 18 of the force exerted by the biasing means. Preferably, automatic adjustment means is incorporated as described below. As shown, the housing 19 is a sliding caliper, and a second main piston 17, Fig. 1, with the associated apparatus is provided. The Belleville springs 46 at between a washer 37, Fig. 2, non- rotatably mounted at the inner end of bore 22, and a sleeve 24 having a screw-thread connection with an adjusting member 29 having a head 31 adjacent the piston head; a torsional spring 36 encircles the head 31 and is fixed at one end to piston 18 to act as a one-way clutch. Sleeve 24 is prevented from rotating by the washer 37 (see Fig. 2). A clearance is provided between head 31 and piston 18 to permit normal actuation and release of the piston. During normal running, an engine-driven pump 58 delivers fluid to the left of auxiliary piston 51 which, through nut 74, draws sleeve 24 and hence member 29 to the right, compressing springs 46. Brake pads 15, 16, now have light rubbing contact with disc 12. For fluid-pressure brake application, chamber 23 is pressurized, whereby piston 18 applies pad 15 and pad 16 is applied by reaction; on pressure release, the brake is released by recovery of a seal 66 surrounding piston 18. After excessive pad wear, fluid-pressure operation of the brake causes such movement of piston 18 leftwards that collar 33 (located across piston 18) tends to pull adjusting member 29 to the left through the agency of a thrust bearing 35 and the head 31. In consequence, member 29 is partly unscrewed from sleeve 24, such rotation being permitted by the one-way spring clutch 36. For parking brake actuation it is sufficient to switch off the vehicle engine, whereupon pressure is lost at 58, 57 and space 56, permitting springs 46 to move sleeve 24, member 29, piston 18 and hence pad 15, to the left and, by reaction, pad 16 to the right. To move the braked car in emergency with the engine not running, nut 74, threaded on sleeve 24, is rotated, whereupon piston 51 is moved until it abuts wall 77 of caliper 19, after which sleeve 24 is drawn to the right, compressing springs 46 and thus releasing the brakes.

Patent GB-1076865-A (GB)
Title: Water-proof sheet materials
IPC: B29C70/62
Filed: 1965-08-04
Abstract: Waterproof sheet material comprises an ethylene copolymer film base, which copolymer has rubber-like properties and a modulus of elasticity lower than that of polyethylene, and on at least one face of the film, fibres or particles in which a portion only of the individual fibres or particles is embedded into the surface of the film so that the film has a pile surface.  The copolymer may be an ethylene-vinyl acetate, ethylene-propylene copolymer such as ethylene-propylene rubber.  Organic or inorganic fibres and particles may be adhered to the film e.g. polyolefin, polyamide, polyester, polyvinyl alcohol fibres, asbestos, punice, vermiculite, slag, glass. The pile material is deposited on the film base whilst the film is heat softened, and the film hardened by cooling.  Mechanical and electrostatic methods of deposition may be used e.g. the pile material may be scattered on the film immediately after the film has been formed by melt extrusion, or the extruded film passed through an electrostatic field and the pile material deposited electrostatically.  The pile material may be deposited as a number of spaced areas.  The waterproof sheet material may be superposed upon a concrete or mortar base using a cement paste whereby the fibres or particles on the film become embedded in the paste, and covering mortar applied to the waterproof sheet, or the waterproof sheet may be applied to the cement or mortar base before it has solidified. Asphalt or other adhesive may be used instead of cement paste.  The sheet may be applied to parapets, vertical walls.  Tests for measuring the adhesive strength of the "piled" films on concrete are described.  In Example (1) ethylene-vinyl acetate copolymer is extruded on an endless belt and asbestos applied by scattering, after which the film is passed through squeezing rolls then cooled and excess material brushed off and removed by vacuum.  Both sides of the film may be covered by scattering pile material on the belt beforehand.  In Example (2) ethylene-vinyl acetate copolymer is extruded on to an endless belt, is heated by an infra red lamp, and nylon fibres are applied, electrostatically insecure fibres being eliminated by suction.  Apparatus for carrying out the process is illustrated.

Abstract: 913,591. Lithographic printing-plate production by silver-salt diffusion processes. GEVAERT PHOTO-PRODUCTEN N.V. Dec. 11, 1958 [Oct. 25, 1957], No. 33431/57. Class 98 (2). The positive image transfer in this process is made on to metal plate not having specially provided nuclei but which metal takes actively part in electrolytic transfer and reduction of the silver salt, and an after-treatment is given to increase the hydrophility of the metal and the oleophility of the transferred silver image. Metals specified are aluminium, zinc, magnesium, copper, lead or alloys thereof; preferably brushed aluminium is used, the negative material is silver chloride in gelatine of medium hardness, and wetting and sequestering agents, of which many are specified, are used in the transfer-developer. The after-treatment is described as with a solution which contains a polymeric substance such as gum arabic or carboxymethyl cellulose, the effect of which can be increased by addition of phosphoric acid and enhanced by incorporation of quaternary ammonium compounds or mercapto compounds. In an example the brushed aluminium sheet and the exposed negative are treated with a specified transfer developer in an apparatus in which the former takes a shorter way than the latter before reaching rubber rollers, then the plate is rubbed with an after-treatment solution including sodium phosphate, cetyltrimethylammonium bromide and formaldehyde in addition to the carboxymethylcellulose and phosphoric acid as indicated above, to result in a printing-plate ready for use. The Provisional Specification states that the power of the silver image to absorb ink is improved by treatment with certain complex iodides. Specification 614,155 is referred to.
