.~.~.~ Including circularly flowing liquid separation agent
DEFINITION
Classification: 209/724
Including circularly flowing liquid separation agent:
(under subclass 208) Methods and apparatus wherein material, as particulate, pulp, slurry or suspension, is delivered to a liquid assorting medium as either (1) a volumetric mass having a rotary movement or (2) as a swirling current to promote deposition due to resultant centrifugal or centripetal forces.
(1) Note. The liquid assorting medium is usually water or an aqueous suspension.
(2) Note. The moving liquid assorting medium is essential to the generation of centrifugal or centripetal forces, not merely additive or supplemental to any such forces generated by the material movement itself. Accordingly, the liquid assorting medium and the material must intersect, rather than travel coincidentally.
SEE OR SEARCH THIS CLASS, SUBCLASS:
12.1+, for combinations of diverse types of separating operations including liquid suspension separating operations; particularly subclasses 13, 16, 17, and 18.
133+, for material acted upon by a gaseous assorting medium.
155+, for material acted upon by a linearly directed current of liquid assorting medium. 172+, wherein material is delivered to a static volumetric mass of liquid assorting medium for gravitational separation relative to the specific gravity of the liquid assorting medium (i.e., sink-float separation).
725+, particularly subclasses 730+ for centrifugal or centripetal force grading deposition of a liquid suspension including the use of additive or supplemental liquid which travels coincidentally with the liquid suspension. See (2) Note supra.
