Abstract
820,586. Electric ovens. COLLINS RADIO CO. March 28, 1957 [Aug. 17, 1956], No. 10242/57. Class 39(3) [Also in Group XXXV] A temperature controlled oven for housing a quartz oscillator plate comprises a ferrite cylinder 12 as a heating resistor mounted within a lagged case 11. The ferrite has current supply connections 13, 14 and is notched at each end to receive a control winding 17, which uses the change of the magnetic properties of the ferrite with temperature change to maintain the temperature constant e.g. at 65‹C.
