DEFINITION

Classification: 205/728

And programmed, cyclic, or time responsive control:

(under subclass 727) Subject matter which also involves (a) storing coded instructions or other data which is used to regulate the object protection, (b) repetitively regulating a sequence of process steps, or (c) regulating the object protection according to preset timing sequences (e.g., limiting various process steps to predetermined durations of time, etc.).

(1) Note. This subclass is not intended to include the use of direct current (DC) pulses which are not clearly repetitive (i.e., with multiple complete cycles) or predetermined.

729, for electrolytic protection of objects containing a metal or metal alloy with programmed, cyclic, or time responsive control; but without involving control responsive to a sensed condition.
