DEFINITION

Classification: 234/24

(under subclass 23) Device wherein the additional means is differentially responsive to the occurrence of a zero or a significant digit, and the control-imposing means is capable of determining the actuation or nonactuation of a tool or group of tools (which has been selected by other means) to represent a zero symbol.

(1) Note. The systematic substitution of a "zero" for a space or other character, or substitution of a "space" for a zero, at every occurrence, is simply a change of code. A device having this function would be classified in one of the appropriate subclasses relating to "coded" punching (see the Search This Class, Subclass note below, for example).

SEE OR SEARCH THIS CLASS, SUBCLASS:

14, for programmed means to change code.

69+, for change of code in a pattern-controlled selective cutting device (see (1) Note above).

96, for means to change or facilitate change of code in a selective cutting device.
