Abstract
Abstract A device for separating fluids having different physical properties is disclosed which utilizes a unique drum having a plurality of substantially horizontal vanes for ''''concentrating'''' in a relatively quite space a quantity of the fluid to be recovered while simultaneously utilizing the forces of surface tension and adhesion of such fluid to cause it to cling to a rotatable disc from which the fluid is scraped and allowed to flow into a central trough from whence it can be recovered, and further processed.

Claim 7
Independent Claim
231 words
A device for separating fluids of differing physical properties comprising: a support frame, means attached to said frame and adapted to provide support in fluid media, a channel member suspended from the underportion of said frame having a flared, scoop portion on at least one end thereof, said channel member and said scoop portion being adapted to be positioned beneath the surface of the fluids in which said frame is suspended, a hollow, nonrotative axle having a longitudinal opening in the upper surface thereof extending transversely across said channel, a pair of end plates rotatably mounted on said axle, a plurality of vanes attached to said end plates equidistantly from said axle and adapted to rotate thereabout in conjunction with said end plates, a series of discs interlockingly secured to each of said vanes and extending inwardly and within the drum formed by said vanes, said discs and said drum assembly being adapted to extend into and beneath the surface of the fluid on which said assembly is floated, wiper blades mounted upon said axle and flexibly biased into scraping engagement wIth the surface of said discs, the bottom ends of said wiper blades being positioned above the longitudinal opening in said axle, a reservoir sump system for receiving fluid as it exits from said hollow axle, and pump means associated with said reservoir sump for removing fluids from said sump.
