DEFINITION

Classification: 494/43

ROTATABLE BOWL:

(under the class definition) Apparatus comprising the receptacle-like member, or one or more elements or portions thereof, of a separator, which member is (a) generally closed insofar as its sidewall structure is concerned and (b) subjected to turning about its principal axis for causing material supplied to it to be divided into two or more components.

(1) Note. While termed a "bowl," and described as "receptacle-like," the member may range from a sphere to an open cylinder.

(2) Note. "Generally closed," as used in describing the sidewall structure, is intended to exclude openings which are the essence of a separating function (e.g., as in separating by filtering), but is not intended to exclude, for example, an opening which is utilized for discharging one or more of the products of a separating operation performed within the bowl.

(3) Note. Where means or structure comprising subject matter for any one of subclasses 82, 83 or 84 below is present, the claiming of the bowl in name only shall not be deemed to mandate original classification here (43).
