DEFINITION

Classification: 234/72

(under subclass 67) Device wherein the alteration is brought about by varying the effect of the sensing means (of the device of subclass 59) with respect to a predetermined portion of a pattern, as follows: (1) disablement of the sensing means, (2) interruption of the transmission of tool-selecting control impulses from the sensing means to corresponding tool-selecting means, or (3) establishment of an alternate or an additional channel for transmission of such control impulses to other tool-selecting means.

(1) Note. See (1) Note under subclass 71, above.

(2) Note. The functions found in machines of this type include the "skipping" of a pattern-field* or a zone of a workpiece (i.e., omission to sense and/or to punch the field or zone in question), and the "transposition" or "shift" of fields (i.e., changing their effective position, as by sensing two such fields in altered sequence.

(3) Note. Fig. 14 illustrates shift of data fields, without alteration of the significance of the data. Columns A-E of the pattern (Fig. 9) now appear in the order C, D, E, A, and B respectively, which may be appropriate to a different form of business record.

SEE OR SEARCH THIS CLASS, SUBCLASS:

13+, for programmed means which can modify the effect of a pattern data (as by skipping over certain fields of data in a pattern). 25+, and 53, for other instances of pattern- controlled operations which may include field suppression, selection, or shift.
