DEFINITION

Classification: 234/16

(under subclass 13) Device wherein the program means terminates the transmission of machine-controlling impulses from one specified portion of the device and effects initiation of transmission of such impulses from another

specified portion of the device.

(1) Note. For original placement in this subclass, a patent must claim means to connect a second input means, as well as means to disconnect a first input means. The mere addition of an overriding control of a single input means (e.g., the operation of keys by a pattern-responsive mechanism at certain times) is found in subclass 20.
