Abstract

809,956. Iron manufacture; carbonyl processes; extracting metals; coating with metals; granulating metals. BRENNAN, J. B. June 2, 1955, No. 15824/55. Classes 72, 82(1) and 82(2) Powdered metals are obtained by feeding molten material, namely metal or metal carbonyl, into a rotating chamber having orifices in the peripheral wall, the material passing through the orifices to form the metal. Metals may be powdered unchanged, or a metal carbonyl may be atomized into a heated space to decompose, thus giving the metal. A halide may similarly be used to yield the metal. The metal producing unit is used to coat metal or non-metal materials with a metallic coating to form a porous strip, and the coating may be stripped off the backing if desired. The coating may be subjected to compaction by being passed between rolls whilst heated by H.F. means. The coating metals include iron and nickel and bases specified are metal, paper, glass, ceramic, quartz, textiles and synthetic materials. Molten material is supplied to a centrifuge 3 and issues through orifices 6 to meet a gas blast from nozzles 14 arid the powdered metal impinges on an endless band 9 kept at a suitable temperature by the shoe 12. A knife 21 strips off the coating and it is consolidated by rollers 15 before being spooled. Heating means 8 and 23 are provided, the former being optionally used when atomizing metals. H.F. heating may be substituted for the gas jets shown. The centrifuge is rotated by a pulley 17. Specification 747.962 is referred to.
