Abstract
197,340. Katatani, S. May 8, 1922, [Convention date]. Resistance materials.- An electric resistance material which does not fuse or oxidize at high temperatures, applicable for example to electric heaters and furnaces, comprises powdered ferrotungsten, ferro-molybdenum, or ferro-titanium, or mixtures of these, mixed with powdered fireclay or magnesite or other material containing a large proportion of magnesium carbonate, the mixture being kneaded and heated to 1500-1600‹ C. A mixture of ferro-tungsten and fireclay powders containing 20 to 30 per cent of fireclay may be kneaded with water, pressed into a mould, allowed to dry and harden, and heated in a fireproof airbight container. Terminal layers of carbon powder kneaded with coal tar or pitch may be placed at each end of the resistance in the mould. The Specification as open to inspection under Sect. 91 (3) (a) refers also to the use of the resistances as lightning-arresters, of other ferroalloys such as ferro-chrome and ferro-silicon, and of any fusible material instead of fireclay. This subject-matter does not appear in the Specification as accepted.
