DEFINITION

Classification: 204/196.05

With programmed, cyclic, or time responsive control means:

(under subclass 196.01) Apparatus having control means for (a) storing coded instructions or other data used to regulate operation of the apparatus, (b) repetitively regulating a sequence of operational steps performed in or by the apparatus, or (c) causing various operations to occur according to preset timing sequences or to last for predetermined durations (e.g., timer switches, etc.).

(1) Note. This subclass does not provide for control means directly responsive to a sensed condition but includes a control means which maintains an operating condition, predetermines apparatus operation, or regulates repetition.

(2) Note. This subclass is not intended to provide for apparatus merely using alternating current (AC), per se.
