DEFINITION

Classification: 494/11

WITH CYCLIC OR TIME CONTROL MEANS:

(under the class definition) Apparatus provided with means for causing the separator, or a component thereof, to operate in accordance with (a) a predetermined sequence of events (e.g., program control by a cam), or (b) the progression of time (e.g., the length of time to be allotted to each of one or more phases of the separating function) as determined by a device having at least the capability of establishing a time interval (e.g., a timer) and possibly having also the capability of relating the time interval to the time of day (e.g., a clock-timer).

(1) Note. The term "automatic" frequently is utilized in describing the operation of the art of this subclass.

(2) Note. The reference to a "cam" in (a) above is not intended to infer that a cam may not be found elsewhere in the class; see, for example, subclasses 47+ below, where the "other movement" may result from the use of a cam.
