Class Information
Number: 83/72
Name: Cutting > With means to monitor and control operation (e.g., self-regulating means)
Description: Apparatus, each of whose parts has a desired operating condition according to a law of operation; such apparatus being provided with a detector for sensing a deviation of a part(s) (or all of the apparatus) from its or their desired operating condition; and including means to modify - in response to a signal or impulse transmitted by said detector - (a) the cyclical operation of such part(s) (or the entire apparatus) to correct the deviated operating condition; and/or, (b) the normal cyclical operation of another part(s) to compensate for the deviated condition; whereby, in either event, the maintenance of a normal cyclical desired operating condition of the apparatus as a whole is achieved.
