DEFINITION

Classification: 205/725

With control responsive to sensed condition:

(under subclass 724) Subject matter in which the object protection 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.

SEE OR SEARCH THIS CLASS, SUBCLASS:

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

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

743, for electrolytic treatment of water, sewage, or other waste water with 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 73, Measuring and Testing, as the residual class for processes and apparatus for measuring or testing, per se. See also the (3) Note in the class definition of Class 73 for additional loci of other measuring and testing processes and apparatus of different types.

324, Electricity: Measuring and Testing, for measuring, testing, or sensing, per se, to determine electrical properties by electrical means even though nonelectrical values may be derived from the electrical properties determined.
