(under subclass 349) Apparatus having a mechanism which limits the period of operation of the device on the workpiece.
(1) Note. Mere cyclical operation of a machine is excluded from this subclass in that the majority of the devices of the subclass will serially laminate successive sandwiches in a definite pattern of operation. The subject matter of this subclass must have the element of control in it, such as, for example, a variable timer that may be present for a particular treatment interval.
