DEFINITION

Classification: 425/155

(under the class definition) Apparatus having a time period limiting means operating independently of the apparatus drive means, which time limiting means causes a change in the operation of the apparatus at the end of the selected time period.

(1) Note. Mere cyclical or synchronous operation of complex apparatus is excluded under this definition. The timing means must be independent to the extent, for example, that a change in apparatus drive speed will not change the period measured by the timing means.
