BOWLS AND MEANS EXTERNAL THEREOF FOR RECIRCULATING MATERIAL:
(under the class definition) Apparatus wherein a receptacle-like member is provided with means, located at least in part outside thereof, for conducting material away from the member and subsequently returning all or a part of that material to the member.
(1) Note. The material leaving and later returning to the member may constitute, for example, (a) material for which a higher degree of separation is desired than could be obtained by passing through the member once, or (b) material which was in excess of the separating capacity of the member upon the occasion of its initial entry thereinto, or (c) leakage which has been collected.
(2) Note. The outside means may include a driven device (e.g., a pump) for moving the material.
(3) Note. The means, while outside, at least in part, of the member, is not necessarily outside of any such structure as may be provided for enclosing the member.
