DEFINITION

Classification: 156/350

(under subclass 349) Apparatus having (1) means to sense a condition or change in condition and in response thereto cause a control operation, or (2) means directly responsive to presence or absence of the work and causing a control operation.

(1) Note. With respect to (1) above, the condition sensed must be something other than the normal cyclical operation of the machine. Further, a change in the normal cycle of operation caused by the intervention of the machine attendant would not be included. With respect to (2) above, the normal cyclical operation of the machine may be maintained or controlled by the presence of work at the work station.

(2) Note. The condition sensed may be a condition or property of the work (either before or after laminating), of

the laminating or working apparatus, or any change in the environment of the apparatus, which sensing means stops, starts or otherwise modifies the operation of the apparatus.

(3) Note. Mere sensing means alone to determine a condition or change thereof without in turn causing a control operation is not sufficient for placement in this or the indented subclasses. A control function of the apparatus must be effected when the sensed condition or change of condition occurs for complete automatic control.

SEE OR SEARCH THIS CLASS, SUBCLASS:

365, for apparatus including safety interlocks. 367, for devices including an electrical control means.

378, for means performing a sensing function and in response thereto causing a signal or indicating means to be actuated rather than a control operation for the apparatus.
