DEFINITION

Classification: 523/303

Controlling process in response to a stated measurement or test:

(under subclass 1) Process wherein control of the treatment or formation of an intentional or desired composition is altered in response to a stated measurement or test.

(1) Note. Measurement or test must be described in more than mere nominal terms. For example, "reacting until an acid value of 100 is reached" is not sufficient since the acid valve is a merely nominally stated desired result; however, a claim which describes specific measurement and specific means for responding to the measurement would be placed herein.

(2) Note. The control aspect relates to treating a previously formed composition or altering or maintaining the ingredient make-up of a composition in response to a stated measurement or test, etc.
