Abstract

895,579. Valve oscillating circuits; R.F. couplings. GENERAL ELECTRIC CO. Ltd. Dec. 16, 1959 [Dec. 3, 1958], No. 41483/58. Classes 40(6) and 40(7). An induction heater comprises a high frequency oscillator which has in series with' a tuned tank circuit a variable inductance whereby to vary the voltage across the tank circuit and hence the kVA available from it. The circuit is essentially a Colpitts oscillator, with feedback over capacitors 6, 7, modified to include the variable inductor 8 connected in series with the tuned tank circuit 2, the tank circuit being inductively coupled to an output circuit by a coil 5.
