Abstract

A control circuit arrangement for regulating the electrical energy supplied to a heating element of the heating apparatus in which the heat produced by said heating element and the heat stored in said heating apparatus aids in heating a member, which you understand a supply voltage spring; switching means connected between said supply voltage source and said heating element; said switching means having at least one control element and being made conductive when the signal supplied to said control element exceeds a predetermined threshold level; means for controlling the rate at which said energy is supplied to said control element; said control means comprising feedback circuit means for supplying energy according to the voltage supplied to said heating element; and a circuit that provides power supply for a predetermined period of time after said control circuit is initially energized, to increase the heat generated by said heating element for a period of time corresponding to the time required to heat said heating apparatus. .
