Abstract
481,243. Electric heating wire resistances. SOC. D'ETUDES ET D'APPLICATIONS INDUSTRIELLES. June 11, 1937, No. 16296. Convention date, June 12, 1936. [Class 39 (iii)] In electric heating elements having a helically wound conductor separated from an outside sheath by a layer of insulating material which is compressed by reduction in the cross-section of the element after the introduction of a metal core inside the conductor, the core is made of metal hardened by cold working and, after compression of the element, the core is annealed and then elongated to facilitate its removal. The space left by this removal may be filled with insulating powder. The metal may be brass composed, for example, of 70 per cent of copper and 30 per cent of zinc.
