Abstract

383,058. Electric induction furnaces. ALLM€NNA SVENSKA ELEKTRISKA AKTIEBOLAGET, Võsteras, Sweden. Nov. 10, 1931, No. 31143. Convention date, Aug. 29. [Class 39 (iii).] In.a furnace without a closed ferro-magnetic circuit the winding 2 is surrounded by a ferro-magnetic shell 3 and annular ferromagnetic plates 4 are inserted between the turns of the winding to conduct the flux between the shell and the surface of the charge.
