DEFINITION

Classification: 96/244

With control means responsive to sensed condition:

(under subclass 243) Apparatus in which means are provided to detect an apparatus or a process characteristic or a change therein and to control or regulate operation of the apparatus or 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 the characteristic or a change therein and to implement an action in the apparatus based upon the detected characteristic or change therein. There must be a positive action made by the apparatus because of the detected characteristic or change therein. An example is a liquid height sensor which opens or closes a valve when a certain level is reached. Another example is a pressure valve in which a certain pressure must be reached before the valve opens to relieve the pressure differential across the valve. Apparatus in which no positive action is made by the single means as a result of the detected characteristic or change therein is not classified in this subclass or in the subclasses indented hereunder, but is classified below. An example of such means would be an overflow means which maintains the height of liquid within a vessel, but without means for implementing any action in the vessel.
