Abstract

505,531. Electric heating-resistances. SIEMENS-PLANIAWERKE AKT.-GES. FUR KOHLE-FABRIKATE. July 8, 1938, No. 20310. Convention date, Nov. 20, 1937. (Class 39 (iii)] The ends of a tubular silicon carbide heating resistance 1 are sealed by solid silicon carbide members 2 of good electrical conductivity. The element is of oval, elliptical, or circular cross-section and is made in one piece.
