DEFINITION

Classification: 95/1

WITH CONTROL RESPONSIVE TO SENSED CONDITION:

(under the class definition) Process in which the separation is regulated by detecting a characteristic or a change in a characteristic of the process and by implementing an action in the process based upon the detected characteristic or change therein.

(1) Note. In this subclass and the subclasses indented hereunder, a single means may be used both to detect the characteristic or the change in the characteristic in the process and to implement an action in the process based upon the detected characteristic or change therein. There must be a positive action made by the means because of the detected characteristic or change therein. An example is the use of a pressure relief valve in which a certain pressure must be reached before the valve opens to relieve the high pressure in the process. Another example is the use of a bimetallic element in a thermostat in which a certain temperature must be reached before a switch is tripped in order to control the temperature in the process. A third example is the use of increased weight on a separating media because of accumulation of a separated constituent to cause the separating media to move to a position of nonuse or regeneration. Excluded from this subclass and the subclasses indented hereunder are processes in which there is no positive action made by the single means because of the detected characteristic or change therein. An example of a process which is excluded and placed below is the flow of liquid over a baffle once the liquid level reaches the top of the baffle.
