401.~ With measuring, sensing, testing, or synthesis operation control responsive to diverse condition


DEFINITION

Classification: 585/401

With measuring, sensing, testing, or synthesis operation control responsive to diverse condition:

(under subclass 400) Subject matter wherein the process involves a definitely recited step of measuring, analyzing, etc., a condition or parameter of the process or in which a condition of the synthesis operation, e.g., temperature, etc., is adjusted in accordance with a different aspect of the synthesis, e.g., strength of catalyst, etc.

(1) Note. A process in which the same operating condition is controlled, e.g., adding heat to a reaction in response to a temperature drop in the reaction zone, is not included in this subclass.
