Abstract

493,499. Electric heating resistances. BACKER, C. B. March 26, 1938, No. 9294. Addition to 484,148. [Class 39 (iii)] The resistance heating-element described in the parent Specification is modified by having the metallic tube or sheath 3 composed of three or more sheets enclosing a resistance coil 1 and insulating powder 2. Outwardly projecting ribs 4 are welded together and the resulting element may be enclosed in a tube 5.
