20080015099 - Separator comprising a spinning drum with a disc stack: A separator including a vertical axis of rotation, a drum having solids discharge openings and a conical centrifugal space, and a disc stack located in the conical centrifugal space. Also included is a plurality of conical discs super-imposed on one another and having disc bores forming at least one rising... Agent: Barnes & Thornburg LLP

20080009402 - Method and apparatus for separating particles: A method and apparatus for separating particles preferentially accelerates particles to a rotating collector, which then reliably conveys collected particles to a discharge with minimal re-entrainment of the particles in the fluid stream. The collector minimizes energy transfer to the fluid and maximizes separation under conditions of high particle loading,... Agent: Loren G. Helmreich

20080009401 - Centrifuge: A centrifuge having a housing having a body and an arm extending from the body, the arm attached to the body at a first end; a chamber defined in the arm; a first tube positioned within the chamber and comprising a porous sidewall; a second tube positioned within the chamber;...
