Abstract:
1. A static separation device for separating mixed matter flowing therethrough comprising: a tube having a first and a second end; said first end of said tube providing an input for the mixed matter; said tube having a generally square cross section defining four generally acute corners; said tube being spirally twisted about a common axis extending between said first and second ends of said tube with four generally acute corners forming four helixes for causing the mixed matter flowing through said tube to rotate within said tube in accordance with said four helixes; said rotation of the matter centrifugally separating high density matter from low density matter flowing through said tube; a plurality of apertures defined in said four helixes for permitting centrifugally separated high density matter to elute said tube; and said second end of said tube for providing an output for the low density matter flowing through said tube.
