Abstract

487,662. Resistance heating elements. SOC. D'ETUDES ET D'APPLICATIONS INDUSTRIELLES, SOC. ANON. Jan. 17, 1938, No. 1506. Convention date, Jan. 20, 1937. [Class 39 (iii)] Powdered insulation is compressed within the space between the walls of a metal tube and a mandrel placed in the position to be occupied by a helical resistance winding. The mandrel is then replaced by the winding, the space within which is filled with powdered insulation or compressed blocks thereof, and finally a shrinkage of the cross-section of the assembled element is effected. The tube may contain more than one winding. Specification 471,252 is referred to.
