DEFINITION

Classification: 72/20.3

Of different operating assemblages:

(under subclass 20.2) Subject matter including regulating the functioning of at least two disparate operating assemblages.

(1) Note. See (1) Note under subclass 20.2 for an explanation of "operating assemblage".

(2) Note. This subclass is the locus of patents disclosing control of a sequence of operations performed by different operating assemblages responsive to a tool. For example, a device wherein a metal-deforming tool strikes a limit switch causing a cutter to cut the product of the tool, and/or causing a handler to discharge the product from the machine, would be found in this subclass.

SEE OR SEARCH THIS CLASS, SUBCLASS:

13.6+, for sequential control of different operational assemblages in a metal deforming machine that uses a roller or roller-like tool.

21.6, for deforming generally wherein the operation of a plurality of operating assemblages is responsive to a device other than a deforming tool.
