DEFINITION

Classification: 235/60.35

(under subclass 60.3) Subject matter wherein the selection of recording elements, or operative portions thereof, which effect recording, is controlled by impulses which are differently timed; that is, the relative timing of the controlling impulses determines the digits which are to be recorded. The differentially timed impulses are usually electrical in nature, as in electrical record controlled calculating machines. However, this subclass receives mechanical machines wherein recording elements are selected by mechanically operated means which are operated at differential times.

SEE OR SEARCH THIS CLASS, SUBCLASS:

432, 433 and 434, for printing and punching devices, respectively, which are operated by differentially timed impulses, when claimed in combination with record controlled calculating structure.
