DEFINITION

Classification: 209/726

Including condition responsive control:

(under subclass 725) Methods and apparatus wherein an operational parameter or status is sensed and a reactionary procedure is executed.

(1) Note. The sensing and reactionary procedure features may be performed by a unitary device (e.g., check valve, etc.) or by distinct interconnected devices (e.g., pressure detector actuating a valve controller, etc.).

SEE OR SEARCH THIS CLASS, SUBCLASS:

1, for a specifically provided, readily distinguishable body undergoing the separating operation used to indicate separating operation efficiency (e.g., coded tracers, tags, etc.).

12.1+, for combinations of diverse types of separating operations including liquid suspension separating, particularly subclasses 44.1+.

548, for halting operation of a separating operation as a result of sensing an abnormal or improper operational parameter or status. See (7) note of the class definition and subclass 509 definition including the notes appended thereto for the statement of classification control.

549, for actuation of a signal lamp or alarm in response to sensing an improper operational parameter or status. See (7) note of the class definition and subclass 509 definition including the notes appended thereto for the statement of classification control. SEE OR SEARCH CLASS
