DEFINITION

Classification: 204/196.02

With control means responsive to sensed condition:

(under subclass 196.01) Apparatus including means for detecting an apparatus or process characteristic or a change therein and for controlling (i.e., regulating) operation of the apparatus or process based on 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 change therein and to implement an action based upon the detected characteristic or change therein. There must be a positive action implemented by a control means as a result of the detected characteristic or change therein.

SEE OR SEARCH THIS CLASS, SUBCLASS:

196.06+, for electrolytic object protection apparatus with measuring, testing, or sensing means but without control means responsive to a sensed condition.

228.1+, for other electrolytic apparatus with current, voltage, or power control means responsive to a sensed condition.

230.2+, for electrolytic apparatus with other current, voltage, or power control means.

400+, for an apparatus which performs electrolytic analysis or testing, per se.

SEE OR SEARCH CLASS 73, Measuring and Testing, as the residual class for processes and apparatus for measuring or testing, per se. See also (3) Note in the class definition of class 73 for additional loci of other measuring and testing processes and

apparatus.
