(under subclass 661) Subject matter wherein the on and off periods of the power supplied to the inductive heating apparatus are automatically regulated according to a preselected result.
(1) Note. The automatic controlling device must include
means to sense a condition and means to vary a condition in response to the sensed condition. Means to maintain a condition constant are included as an automatic control where the system includes means to sense deviations from the condition and to adjust the system to maintain the desired value constant.
