Patent number: 5771922Abstract: The present invention, in one embodiment, teaches a flow restrictor which accomplishes within a single unitary integral device cyclonic separation of larger, heavier solids from lighter smaller solids; collection of retained solids in a relatively large collection chamber; straining of certain solids to further protect the device from plugging; and flushing a fluid, e.g. the primary flow stream, through the device to facilitate removal of collected solids.In one embodiment a device according to this invention has a main body with a fluid inlet and a fluid outlet. Fluid flowing in through the inlet encounters a vaned end of a hollow mandrel with one or more vanes or a mandrel with a deflector thereon or both which induce turbulent flow in the fluid and directs solids entrained therein away from the mandrel to a solids collection area or chamber within the main body.Type: GrantFiled: October 23, 1995Date of Patent: June 30, 1998Inventor: Raymond E.

Patent number: 5690813Abstract: An apparatus for separating contaminated waste water into a substantially uncontaminated homogeneous extract water portion and into a heterogeneous raffinate fluid portion. Upon being subjected to sufficient circular flow, in an environment emulating the action of a centrifuge, the heavier liquid and solid components are caused to gravitate out of the waste water. This apparatus is constructed with an elongated housing means which is preferably disposed between a water storage tank and fluid contaminant discharge device. Contained longitudinally within the elongated housing is a separator chamber having a portion of a frustoconically shaped centrifugation surface which directs the incoming waste water into a turbulent and circular pattern. As the waste water gains momentum during this centrifuge-like flow pattern, it abruptly strikes a substantially vertical impact plate which precipitates the forced separation of the impurities and contaminants from the waste water.Type: GrantFiled: July 9, 1996Date of Patent: November 25, 1997Inventor: Christopher Frank Coale

Patent number: 5639366Abstract: A solids concentrator for a liquid and solid mixture utilizing a first container including an upper portion and a lower portion. The upper portion has a transverse dimension that is larger than the transverse dimension of the lower portion. A second container fits within the first container and includes upper and lower portions that are configured to fit within the first container. The upper portion of the first and second containers forms a channel or chamber therebetween. Another chamber is formed between the lower portions of the first and second container, but is narrower across than the first chamber. The flowable liquid and solid mixture is introduced into the first chamber to induce a swirling flow to the second chamber and the inner space of the second container at the bottom of the concentrator. A solid-rich portion of the liquid solid mixture is removed from the lower portion of the inner space of the second chamber or the second chamber itself.Type: GrantFiled: September 1, 1995Date of Patent: June 17, 1997Assignee: Bazell Technologies CorporationInventors: Graydon C.
