DEFINITION

Classification: 494/1

WITH CONDITION RESPONSIVE MEANS:

(under the class definition) Apparatus provided with means

which reacts to a condition, or a change of condition, of the separator, or the environment of the separator, or the material entering, within, or departing from the separator, the reaction of the means serving as a response to the condition or the change therein.

(1) Note. The means may range from a relatively sophisticated system for controlling the operation of the separator, which system may include a means to sense a condition and a means to respond to the information sensed, to a mere element of the separator, which element, by virtue of, for example, (a) its design or (b) the material of which it is formed inherently reacts to a condition to which it is exposed, subjected, etc.
