Title: Improvements in or relating to copper base sintered metal compositions and articles such as bearings, made therefrom
IPC: C22C32/00
Filed: 1944-09-06
Abstract: A sintered metal composition comprising 0.5-5 per cent. nickel or cobalt, 0.1-1 per cent. silicon, 0.01-1 per cent. phosphorus and the balance substantially all copper, is formed by mixing together copper, nickel or cobalt, silicon and phosphorus powders in the required proportions, pressing, sintering and then age-hardening to precipitate nickel or cobalt silicide as a dispersed phase.  As pure silicon readily oxidises it is preferable to form nickel or cobalt silicide which is then comminuted to a fine powder and included in the powder mixture instead of nickel or cobalt and silicon powder. The composition is intended more particularly for use in bearings, which may be made in varying degrees of porosity.  The bearing properties of the copper may be modified by the addition of small amounts up to 10 per cent. of cadmium, lead, zinc, tin, thallium, babbit metal or graphite.  Specification 541,471 is referred to.ALSO:A sintered metal composition comprising 0.5-5.0 per cent nickel or cobalt, 0.1-1 per cent. phosphorus and the balance substantially all copper is formed by mixing together copper, nickel or cobalt, silicon and phosphorus powders in the required proportions, pressing, sintering and then age-hardening to precipitate nickel or cobalt silicide as a dispersed phase.

Abstract: Organopolysiloxane oils, resins and liquids or gums convertible to the solid, elastic state, which have been made by polymerizing lower molecular weight siloxanes with alkali-metal compounds, are stabilized (against deterioration at elevated temperatures) by incorporating therein organophosphorus compounds, a long list of which is given.  Alkali metal compounds specified are alkali metal (Na, K, Li, Rb, Cs) hydroxides, alkoxides, thioalkoxides, silanolates, complexes of aromatic hydrocarbons such as naphthalene or anthracene; compounds of the formula (ROH)xMOH, where R is a hydrocarbon radical and M is an alkali metal, and alkali metal salts of organopolysiloxanes.  The stabilized convertible siloxanes containing Sibonded hydrocarbon and/or halogenated hydrocarbon radicals and possibly some -Si-R-Si-groups, may be compounded in known manner with fillers, e.g. titania, silica aerogel, diatomaceous earth, fumed silica, g -alumina, calcium carbonate and polytetrafluorethylene particles and fibres, curing agents, benzoyl peroxide, t.-butylperbenzoate and 2,21-azobis-isobutyronitrile, compression set additives, and cured.  In examples: (1,2) a methyl siloxane oil made by intercondensing octamethylcyclo-, and decamethyl-tetrasiloxanes in the presence of KOH was stabilized by adding triphenyl-phosphate or other organophosphorus compounds, and then stripped of low-boiling polymers; (3) a similarly made oil containing methyl and phenyl radicals was also stabilized by triphenyl phosphate; (4, 5, 6) alkali catalysed convertible siloxanes were stabilized by adding various organophosphorus compounds thereto and then compounded with fillers &c. in known manner.  Compositions for coating heat-resistant cloths are made by dispersing the stabilized siloxanes together with fillers and curing agent in liquid media, e.g. benzene, xylene and toluene. The compositions find use as insulating materials for electrical conductors, gasket materials, shockabsorbers and in making heater ducts.

Abstract: 1365467 Anchor bolts K B SIKSTROM 11 April 1973 [13 April 1972] 17335/73 Heading F2H An expansion bolt comprises a screw 10 co-operable with an internally threaded expansion member 13 having wedge surfaces 16, 17 which co-operate with wedge surfaces 18, 19 formed in each of a plurality of clamping jaws 20 retained by elastic rings 21, 22 and by abutment with a stop member 27, 28 on the screw, one of the wedge surfaces (17 in Fig. 1) of at least a pair of co-operating wedge surfaces having a radially extending projection 25 guided in a longitudinal groove 23 in the other of the pair (19 in Fig. 1) such that on expansion of the jaws 20 the expansion member engages the stop member 27, 28 to limit screwing and any subsequent axial movement of the screw and expansion member together relative to the jaws effects further expansion of the jaws until the projection 25 engages an abutment surface 24 at the end of groove 23. Thus if the bolt is secured in a bore in rock with the projection 25 spaced from the surface 24 and the rock then weakens, any movement of the screw out of the bore results in further expansion of the jaws. The projection 25 and groove 23 also prevent rotation of the expansion member 13 within the jaws 20. The jaws 20 may be of plastics material and preferably are eight in number in which case the expansion member 13 is formed as two integral 8-sided conical sections 14, 15. If desired however the sections 14, 15 may be separate whereby, if two sets of jaws are provided spaced by a sleeve, the bolt can be expanded at different rates at each end.
