Device under cubclass 13 wherein the program means modifies a code* of substitutes one code for another.
(1) Note. The program means found in this subclass does not select tools directly, but effects a change in the system of tool selection (i.e., a change of code, such for example as the substitution, at certain points only in the sequence of operations, of a "space" symbol for a "zero" in response to a "zero" impulse).
(2) Note. The automatic insertion of zeros or suppression of zeros while punching numerical data is an example of "change of code". This auxiliary-operation, if arranged to occur only at predetermined points in the sequence of machine cycles, is said to be "programmed"; if, however, it takes place whenever a certain condition or combination of conditions should arise (e.g., upon detection of an initial zero in numerical data received from a keyboard or a pattern-reader) it is a randomly effected change of code, classifiable in subclasses 22+.
SEE OR SEARCH THIS CLASS, SUBCLASS:
24, for means to automatically insert or to suppress the punching of a zero symbol, under the control of randomly effective operating conditions.
96, for means to change or facilitate change of code, in a selective cutting device.
