DEFINITION

Classification: 205/743

With control responsive to sensed condition:

(under subclass 742) Subject matter in which the water treatment is regulated by detecting a characteristic or a change in a characteristic of the process and by implementing an action in the process based upon the detected characteristic or change therein.

(1) Note. In this subclass and the subclasses indented hereunder a single means may be used both to detect a characteristic or a change in a characteristic of the process and to implement an action in the process based upon the detected characteristic or change therein. There must be a positive action made by a control means because of the detected characteristic or change therein.

641+, for electrolytic erosion resulting in a change of workpiece shape or surface configuration with control responsive to a sensed condition.

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

744, for electrolytic treatment of water, sewage, or other waste water with programmed, cyclic, or time responsive control; but without involving control responsive to a sensed condition.

775+, for electrolytic methods of analysis or testing, per se. See the (1) Note in subclass 775. SEE OR SEARCH CLASS
