DEFINITION

Classification: 204/608

With programmed, cyclic, or time responsive control means:

(under subclass 606) Apparatus which is provided with control means for (a) storing coded instructions or other data which is used to regulate operation of the treating apparatus, (b) repetitively regulating a sequence of operational steps performed in or by the treating apparatus, or (c) causing various system operations to occur according to preset timing sequences or to last for predetermined durations of time (e.g., timer switches, etc.).

(1) Note. This subclass and the subclass indented hereunder includes any control means which maintain an operating condition, predetermine apparatus operation, or regulate repetition.

(2) Note. This subclass and the subclass indented hereunder are not intended to provide for apparatus merely using alternating current (AC), per se.
