223.~ With destruction sensing and preventing means


DEFINITION

Classification: 60/223

(under subclass 200.1) Apparatus having means sensing an abnormal condition which might destroy the apparatus and functioning to take corrective action against the destructive

condition.

(1) Note. This definition does not include a device which senses a normal variation in conditions to effect a control function, even though such device might be capable of sensing a suddenly presented abnormal condition. For example, a fuel control device responsive to motive fluid temperature to maintain a predetermined power output would not be classifiable under this definition but would be classified in subclasses 233+. However, a fuel control device designed to function only when the motive fluid temperature reaches a temperature above which it would be destructive to the apparatus would be classifiable under this definition.
