DEFINITION

Classification: 337/116

(under subclass 115) Subject matter including significant details of means whereby a circuit is intermittently or cyclically opened and closed at constantly recurring intervals under the influence of an electrothermally responsive vaporizable or expansible fluid device.

(1) Note. For other intermittently or cyclically controlled means employed in devices of this class, see the subclasses listed under SEARCH THIS CLASS, SUBCLASS in subclass 92.
