Title: Method for bonding a rubber to a polyolefine and products made thereby
IPC: C08J5/12
Filed: 1966-01-28
Abstract: 1,141,029. Rubber polyolefine laminates. PNEUMATIQUES CAOUTCHOUC MANUFACTURE ET PLASTIQUES KLEBERCOLOMBES. 28 Jan., 1966 [28 Jan., 1965], No. 4020/66. Heading B5N. [Also in Division B2] A method of bonding a rubber to a polyolefine having a melting index of less than 0À15 comprises contacting said rubber and said polyolefine, preferably in a mould, and applying heat and pressure, the rubber being vulcanized prior to or during the bonding. The polyolefine which may be a copolymer may be used in powder form or as a film or sheet and is preferably a polyethylene. Specified rubbers are natural rubber, cis 1 - 4 - polyisoprene, cis - polybutadiene, ethylene-propylene copolymers, terpolymers of ethylene and propylene with a non- conjugated diene, styrene-butadiene copolymers, terpolymers of butadiene and styrene with a carboxyl containing unsaturated monomer, butadiene-acrylonitrile copolymers, terpolymers of butadiene and acrylonitrile with a carboxyl containing unsaturated monomer, polychloroprene, butyl rubber, chlorosulphonated polyethylene and polysulphides. The process of the invention may be used for bonding two rubbers or for bonding a rubber to a polyolefine of melting index greater than 0À15, the polyolefine having a melting index of less than 0À15 being interposed between the components. The products may be used on tyres, conveyer belts and as pipes.

Title: Improvements in or relating to the extrusion of metal billets
IPC: B21C23/32
Filed: 1956-02-09
Abstract: 795,989. Extruding. BABCOCK & WILCOX CO. Feb. 9, 1956 [May 31, 1955], No. 4065/56. Class 83 (4). In the extrusion of heated metal billets 6, a preformed homogeneous disc 12 of agglomerated glass powder is used at the entrance to the die orifice 5. The billet, which may be of stainless steel, is heated externally to the extrusion temperature and a quantity of glass powder is placed in its bore 7. The billet is then rolled over an asbestos pad coated with glass powder whereby during the rolling, layers 9, 10 of glass are formed on the inner and outer surfaces of the billet. The glass disc 12 may be formed from powdered window glass with a binder of sodium silicate which is compressed in a die assembly 20, 22, 24, Fig. 2 (not shown), to give the required shape. The bore 13 of the disc is equal to or slightly larger than the diameter of the die orifice 5. For extruding relatively low melting point metals, glass powder having a low softening point is used and in this case phosphoric acid is used as a binder. Alternatively instead of using a binder, the disc may be made by sintering a compacted or uncompacted body of glass powder. Examples are given of the grain sizes of the glass powder, the density of the disc, and the dimension of a particular disc. Comparison is made between the use of a glass disc of the invention and a pad of glass fibres. Specifications 607,285 and 784,492 are referred to.

Title: Vehicle hydraulic braking systems
Inventor: HARBIDGE JOHN
IPC: B60T8/42
Filed: 1961-02-03
Abstract: 959,691. Hydraulic braking systems. JOSEPH LUCAS INDUSTRIES Ltd. Jan. 30, 1962 [Feb. 3, 1961], No. 4106/61. Heading F2F. In a vehicle hydraulic braking system hydraulic pressure utilized for applying the brake to a wheel is generated by a pump driven from that wheel. Actuation of the brake pedal 5 causes fluid to be supplied from a master cylinder 3 through a passage 20 in a shuttle 15 to a brake cylinder or cylinders 9 to move the shoes into contact with the disc or drum. As the pressure increases the shuttle 15 is moved downwardly against a spring 16, thereby cutting off communication between the master cylinder 3 and the cylinders 9 except by way of non- return valve 8 which has a relatively strong spring-loading. When the shuttle descends so that groove 18 is opposite port 21, the cylinders 9 are placed in communication with the pump 12 which is in a circuit comprising reservoir 13 and non-return valve 11. As the shuttle descends further it gradually restricts the return of fluid to the reservoir 13 as it closes the gap between a spigot 15a and the inlet 10 with the result that a gradually increasing proportion of the pump output pressure is applied to the cylinders 9. The pump output will vary with the angular velocity of the wheel and thus in the event of the wheel locking the cylinders are subjected only to the pressure in the master cylinder and the brakes are temporarily released.

Abstract: 233,466. Railing, A. H., and Jakeman, R. G. Feb. 23, 1924. Drawings to Specification. Rotary converters.-To eliminate pulsations from the continuous-current voltage of rotary converters, the continuous-current sides of a pair of converters are connected in series or in parallel, and the alternating-current sides are operated in parallel from the supply through their respective transformers so that the electromotive forces supplied to the two converters differ in phase by 30 electrical degrees. The requisite phase difference in the case of 3-ring converters is obtained by connecting the primary windings of the two transformers in star and delta respectively, the secondary windings being both star- or both delta-connected. Alternatively, the two primary windings may be connected in the same manner, and the secondary windings may be in star and delta respectively. A single transformer having one primary winding and two differently connected secondary windings may be employed. In the case of 6-ring converters, the transformer secondary windings have a diametral star and a double delta connection respectively. Tooth ripples may be eliminated by providing an odd number of armature slots for each 60 electrical degrees of the armature, the relative angular positions of the two armatures of the converters differing by half a tooth pitch.

A griller tray raising and lowering mechanism comprises two lifting arms 10 and 11 each having its free ends pivotally mounted at or near the ends 10a and 11a on a support 6 and each having its centre portion adapted to support the tray 12 on opposite sides, of the tray 12 and means mounted on the support 6 to raise and lower the arms 10, 11 in unison and so raise and lower the tray 12 relative to the support 6. The support 6 is a carrier plate which has two bearing brackets, 8, and two apertures, 9. Each lifting arm is U-shaped and has the free end of each leg bent inwardly to form a pair of coaxial pivot pins 10a and 11a which are inserted into apertures in the end flanges 7 of the carrier plate. The arms 10 and 11 extend from the apertures, in the end flanges, above and across the centreline of the carrier so that they cross in such a way as to be in contact with each other. A cam shaft 13 having cam portions 14 and 15 is rotatably mounted in apertures 8a formed in bearing brackets 8 and is provided with a turning handle 16. The legs of arms 10 and 11 rest on top of cam portions 14 and 15 so that rotation of the cam shaft 13 will alter the point at which the legs cross and so raise or lower the griller tray 12. The cam shaft 13 may be maintained in any one predetermined position by means of a collar 17, welded to the shaft 13 between cam portion 14 and bracket 8, which projects through aperture 9 to bear on a spring steel strip 18.
