DEFINITION

Classification: 72/128

With modification or control of temperature or work, tool or machine:

(under subclass 127) Subject matter including a step of, or means for, changing or regulating the degree of heat content of the work*, the deflector* or any part of the deforming instrumentality wherein the deflector functions.

(1) Note. Included within the concept of "regulating" is preventing the temperature from changing. For example, a cooled bearing in the machine, or a heated deflector operating on hot work, will warrant original placement of a metal deflecting patent having such claimed structure into this subclass (128).

(2) Note. The schedule of this class (72) contains other subclasses pertaining to temperature modification or control in other deforming operations.
