DEFINITION

Classification: 205/729

With programmed, cyclic, or time responsive control:

(under subclass 724) Subject matter which 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.

725+, for electrolytic protection of objects containing a metal or metal alloy with control responsive to a sensed condition.

728, for electrolytic protection of objects containing a metal or metal alloy involving both control responsive to a sensed voltage and programmed, cyclic, or time responsive control.

744, for electrolytic treatment of water, sewage, or other waste water with programmed, cyclic, or time responsive control.
