Abstract

474,317. Supply systems for heating arcs. I. G. FARBENINDUSTRIE AKT.- GES. Oct. 14, 1936, No. 27920. Convention date, Dec. 7, 1935. [Class 38 (iv)] [Also in Group XI] A furnace arc is started by means of high frequency derived from the furnace supply circuit by means including an adjustable transformer or an induction regulator T to produce a phase displacement. Chokes E<1>, E<2> tuned to the capacities of the electrode guide sleeves D<1>, D<2> and blocking condensers F<1>, F2 are arranged as shown.
