Abstract

1,61,959. Automatic temperature control systems. H. E. PETERSON. Dec. 1, 1964 [Dec. 4, 1963], No. 48823/64. Heading G3R. A resistance heating system for regulating the amount of energy transferred to a load 26 such as a metallic rod, wire or sheet to be heated prior to a working process comprises a step-down transformer 11 having its secondary winding 21 connected to the load 26 and its primary winding 10 connected over a saturable reactor 19 and a switch 7 to an A. C. supply 5, 6. A signal representative of the temperature of the load 26 is derived from a thermocouple 27 and is compared with a reference in a comparator 32 the output from which is applied to control the conduction of thyristors in a power supply 12 connected to the control winding 20 of the saturable reactor 19. The arrangement is such that variations in load temperature result in compensating variations in the impedance presented by the saturable reactor 19 whereby the energy supplied to the load is automatically regulated to maintain the load temperature at a constant value determined by the setting of comparator 32.
