ABSTRACT:
A continuous system for separating acceptable from unacceptable synthetic rubber seals and other parts according to their specific gravity comprising a tank having a flotation chamber and an exit or collection chamber. Fluid of a given specific gravity such that the acceptable parts will float therein enters the flotation chamber in such a manner as to produce a rolling or turbulent flow therein. The rolling flow agitates the parts to liberate entrapped air therefrom permitting the parts true buoyancy to float the acceptable parts or sink the unacceptable parts. The floating parts are then swept over an outlet weir into a collection basket by means of a two dimensional fluid flow over said weir.
