Title: Improvements in or relating to the production of cable sheaths and other tubular metallic bodies
Inventor: LATIN AUBREY
IPC: C22C1/04
Filed: 1950-08-29
Abstract: A cable sheath or other tubular body is made from a mixture of lead and aluminium powders by powder metallurgy (see Group XXII). The mixture may be a lead-rich mixture containing 5 per cent.-15 per cent. by weight of aluminium, or an aluminium-rich mixture containing 5 per cent.-50 per cent. by weight of lead.  The mixture may also contain up to 5 per cent. by weight of tin, lithium, magnesium, titanium, zinc, antimony or bismuth or two or more of them.ALSO:A tubular metal body such as a cable sheath is made by compacting and mechanically working a mixture of lead and aluminium powders which may be a lead-rich mixture containing 5 per cent. to 15 per cent. by weight of aluminium or an aluminium-rich mixture containing 5 per cent. to 50 per cent. by weight of lead.  The mixture may also contain up to 5 per cent. by weight of tin, lithium, magnesium, titanium, zinc, antimony or bismuth or two or more of them.  The aluminium powder preferably passes a 240 mesh British Standard Sieve and the lead powder a 300 mesh sieve and the powders may be mixed in a ball mill containing porcelain balls and pieces of hard aluminium sheet.  After mixing the powder may be compacted to form a billet which is subsequently worked as by forging, rolling or extruding before being extruded in tubular form or alternatively the powder may be fed directly into the receiver of an extrusion press.  The compacting is preferably carried out at temperatures up to 300 DEG C. at pressures from 10 to 20 tons per square inch, but when extruding aluminium-rich powder mixtures, the temperature is preferably in excess of 400 DEG  C.  The compacted billet may be sintered, before being worked, by maintaining it at 450 DEG  C. for six hours or at 600 DEG  C. for five hours by immersing it in a lead bath.  In an example, the aluminium-lead powder mixture was compacted at 250 DEG  C. at 20 tons per square inch to form billets of 1 3/4 inches diameter and three inches long which were then sintered in air at 450 DEG  C. and extruded at 295 DEG  C. at a pressure of 20 tons per square inch.
Patent GB-583862-A (GB)
Title: New composite materials
IPC: C08L75/00
Filed: 1943-12-21
Abstract: Composite materials are made by bringing into uniform admixture an organic di-isocyanate modified polyester-amide and a partially hydrolysed leather, that is, leather which has been heated with water until its fibrous nature has disappeared.  The leather may be boiled with water, filtered and compounded with the polyester-amide, or it may be compounded with the polyester-amide and water on rolls heated to 70-100 DEG  C., the mix being heated until dry.  Usual proportions are 25 to 175 parts of hydrolysed leather per 100 parts of polyesteramide.  The material may be cured in the presence of formaldehyde, a formaldehyde-liberating substance, or a dichromate, and preferably also in the presence of an acid or a material which is substantially neutral, but which develops acidity under curing conditions.  Curing is effected by heating at 100-150 DEG  C. under pressure or in hot air.  Additional p  ingredients are fillers, other plastic materials, detackifying agents, plasticisers, softening agents, dispersing agents, stabilisers, anti-oxidants and pigments. The materials may be shaped or calendered on to a substrate, if desired, in the presence of solvents or swelling agents.  The materials are used to make petrol and/or oil-resistant articles of all kinds, for example, gaskets, packings, hose, diaphragms for pumps, flexible containers, for rollers, blankets and stereos for use in the printing industry, and for the construction of balls for games, coated or laminated fabrics, including protective clothing, water-proof garments, shoe uppers, slippers, conveyer belting, upholstery, leather-cloth and floor coverings.  In examples, the organic di-isocyanate modified polyesteramide of example 7 of Specification 580,524 is compounded with boiled leather, or with leather and water on heated rolls, and the dry mix is milled with ingredients such as stearic acid, titanium dioxide, hexamethylolmelamine hexamethyl ether, 2 : 4-dichloro-1-naphthol, tricresyl phosphate, carbon black, and turkey red 2G, sheeted off the mill and mixed with a benzene and ethanol mixture.  the dough is then spread on to a cotton twill fabric, the solvents allowed to evaporate and the whole cured.  Specifications 553,733 and 580,742 also are referred to.

Title: Processes for cleaning the surfaces of continuously cast strips
IPC: B21B3/00
Filed: 1975-05-20
Abstract: 1506462 Continuous casting LEICHTMETALL GmbH 20 May 1975 [20 May 1974] 21390/75 Heading B3F [Also in Division C3] After being cast between two belts of strip steel 7 or of mould parts joined in series-each belt bearing a protective layer of particulate material-a strip of metal, e.g. Al, Zn or an alloy thereof, is sprayed with water as from nozzles 9, in order to remove particles picked up from the layers on the belts. In the case of strip steel belts 7, which bear thicker layers, if the water pressure is insufficient to clean the cast strip, brushes 8 may be used also, and spray from further nozzles 12. The excess cooling may be compensated for by heating of the strip before it passes, by way of feed rolls to a rolling mill. A nozzle or several nozzles may be moved across the strip and back during casting. The nozzles may be offset from one another both in a direction transversely of and in the direction of strip movement. They may all be carried by a beam movable transversely of the strip. On each side of a cast strip up to 2000 mm. wide and 10-35 mm. thick, 200-1000 litres/  min. are sprayed at a pressure of 2-300 atm. The protective layers may be of carbon for lubrication and conduction and Kieselguhr bound with polyvinylpyrrolidone which decomposes with the heat so that particles transfer to the strip. The layers, in the case of the belts of mould parts, are sprayed on after regions (6) where the parts are cooled by water spray during return to the feed end of the machine.

Title: Improvements in compressed fluid braking apparatus, particularly for railway vehicles
IPC: B60T15/30
Filed: 1957-07-09
Abstract: 820,297. Fluid pressure brakes. WESTING- HOUSE AIR BRAKE CO. July 9, 1957 [July 19, 1956], No. 21676/57. Class 103 (1). In a compressed fluid braking apparatus, the service valve device 7 automatically controls the application and release of brakes in dependence on the reduction or restoration of pressure in brake pipe 2 relative to pressure in a control reservoir 3 which is charged through communication 12, 32a, 33, 42, 46, 14, the service valve device 7 being such that in response to an initial reduction in brake pipe pressure insufficient to cause brake application, it interrupts the charging communication at one point (32a) and causes the supply of fluid to a valve 8 to move that valve to interrupt the charging communication at a second point (42), fluid so supplied being released on brake release at a rate which is so restricted that reopening of the charging communication coincides substantially with full brake release. The fluid is supplied to a chamber 32 of valve device 8 via passage 31 and chamber 32a from a chamber 34 normally connected to the control sylinder 3, on slight reduction in brake pipe pressure the valve 39 of valve device 8 moves down to cut the charging communication at 42 and connect the branch 14 of brake pipe 2 with a quick-release volume 54 via chamber 44, passage 53 and choke 60 to locally reduce brake pipe pressure to cause service valve 7 to move further to overcome spring 27 and connect the auxiliary reservoir 4 to the brake cylinder 5, via passage 49, valve 51, chamber 23 and passage 19, the bore 24 in valve stem 21 being closed by contact with valve 51. On brake release due to restoration of pressure in brake pipe 2, valve 21 moves down due to increase in pressure in chamber 13 to permit exhaust of fluid from brake cylinder 5 through passage 19, chamber 23, bore 24, chamber 25, passage 55 and choke 56, the fluid in chamber 32 of valve device 8 also exhausting through passage 31, chamber 30, passage 19 where it connects with the brake cylinder exhaust communication, so that the control reservoir charging communication is completely opened on complete brake release. The valve device 8 also controls the charging communication to the auxiliary reservoir.
