Abstract

511,515. Electric resistance furnaces. ESSMANN, F., and DELMHORST, W. Feb. 18, 1938, No. 5146. Convention date, Nov. 16, 1937. [Class 39 (iii)] A resistance furnace of circular cross section has a number of heating elements e, arranged in annular grooves f in a fireproof wall b. To facilitate the exchanging of the elements the grooves are joined tangentially by passages g through the insulating layer c and the outer metal covering d. Each complete heating ele-, ment consists of coils e, Fig. 4, lying in adjacent grooves and joined by a bridge h.
