DEFINITION

Classification: 408/8

(under the class definition) Device including means for: (a.) detecting any of the following characteristics: a state or property, a change in a state or property, or the occurrence of a predetermined event, in any of the following: the work, the product of a machine, the machine itself, or the environment of the machine affecting the operation thereof; (b) initiating (as a direct result of such detection) a force or impulse other than that generated or transmitted by the detecting means; and (c) regulating or modifying (as a direct result of such initiation) the operation of said machine.

(1) Note. The control systems of this and indented subclasses are similar in concept to control systems of other classes; particularly, Class 72, Metal Deforming, especially subclasses 6+; Class 83, Cutting; Class 173, Tool Driving or Impacting, especially subclasses 2+, and Class 226, Advancing

Material of Indeterminate Length, especially subclasses 10+. The total operations and the claimed combinations are, of course, different; but, the control systems, per se, found in these other classes are usually analogous to those herein and may be applicable to the machines of this class (Class 408).

SEE OR SEARCH THIS CLASS, SUBCLASS:

3, for a templet responsive control means.

5+, for control structure adapted to stop the operation of the cutting machine.

SEE OR SEARCH CLASS 364, Electrical Computers and Data Processing Systems,

130+, for data processing control systems wherein the control system is claimed generically, and subclasses 474.1+ for the application of a computer in the manufacturing of a product which includes cutting or punching.
