Abstract

648,027. Induction heating. ALLMANNA. SVENSK A ELEKTRISKA AKTIEBOLAGET. Nov. 9, 1948, No. 29058. Convention date, Nov. 15, 1947. [Class 39(iii)] An induction furnace winding 1, with an iron shell 2, surrounding workpieces 3, has capacitors 4 connected in parallel with its end portions, and one or more inductances 5 in parallel with its centre portion, to compensate for the decrease of inductive field strength at its ends. Specification 648,026 is referred to.
