Patent number: 8025801Abstract: Simultaneous source-sink flow, or radial counterflow, is driven by a centrifugal pump disposed within a casing. Radially outward source flow of brine goes into a shrouding tank and concentrates while a radially inward sink flow of fresh water flows back over the pump to axial extraction. An axial pump drives sink flow and axial extraction. Convergent sink flow passes under an inductor to an axial exhaust port. Induced viscosity and inductive repulsion hinder the passage of brine in sink flow, so only fresh water can reach the axial exhaust port. Crystallization of scale-forming salts is aided by Joule heating from the inductor. Solvent and gases are continuously axially extracted in sink flow, favoring crystallization. Sodium chloride is cooled and crystallized in the shrouding tank. Brine comprising other salts flows out of the tank to treatment by suitable means. Thus brine is separated into fresh water, crystallized salt, and concentrated brine.Type: GrantFiled: August 16, 2007Date of Patent: September 27, 2011Assignee: McCutchen Co.Inventor: Wilmot H. McCutchen

Patent number: 7757866Abstract: In an embodiment, axially-fed slurry can be continuously separated into clarified liquid, stripped gas, and thickened sludge in radial counterflow between counter-rotating coaxial centrifugal impellers. One impeller comprises an annular crossflow filter through which liquids are extracted. At the periphery of the impellers, where they are narrowly separated, the sludge is shear thickened into an extruded paste. Suspended solids in the feed pass over the surface of the rotating annular crossflow filter by the shear lift effect, and the vortex-wall interaction jets water radially inward from the periphery, dewatering the sludge. Evolved gases, oils, and fractions lighter than water flow radially inward to the impeller axis through radial vortices in a shear layer between the impellers, and are extracted through an axial exhaust conduit. Feed has long residence time so that separation is complete and continuous. Municipal wastewater, produced water, beverages, food, and scrubber sludge are discussed.Type: GrantFiled: December 20, 2007Date of Patent: July 20, 2010Assignee: McCutchen Co.Inventor: Wilmot H.

Patent number: 7520996Abstract: The filter removes volatile, particulate and water-based contaminants from a fluid, such as lubricating oil, of a different density than the contaminants. The device has a cone shaped, jet-propelled, helical-spiral wiper rotor creating centrifugal forces that separate the volatile and heavier particulate matter. Ports in a base assembly facilitate removal of the separated contaminants. A settling tank with vertical grid filter minimizes turbulence for further separation of heavier particulate matter. A volatile tank with vertical grid filter and flow restrictor minimizes turbulence to allow volatiles to rise from the fluid. A filter tank filters out remaining particulate matter from the fluid. A combination of flow restrictors and baffles minimize cross-contamination, thereby maximizing purity of oil returned to the engine. The collection tanks are easily cleaned and reused.

Patent number: 7488427Abstract: System and methods for collecting and preparing fat for autologous fat tissue transplantation. The system includes syringes, filtering and transferring assemblies coupled with the syringes, a centrifuge and a centrifuge insert releasably coupled with the centrifuge. Substances, including oil, fat, and denser substances, such as tumescent fluid, connective tissue, hormones and/or other non-fat substances, are harvested through a cannula into a syringe. Syringes are placed in the centrifuge insert, and subject to centrifugation. Centrifugation stratifies the substances into a top oil stratum, a middle fat stratum, and a bottom denser substance stratum. Denser substances are filtered out of the syringes during or after centrifugation. Oil is removed through an aspiration port in the plunger head of the syringe plunger. Fat is transferred from the first syringe into one or more smaller syringes through an adapter in the assembly coupled with the first syringe and the smaller syringe.Type: GrantFiled: April 23, 2007Date of Patent: February 10, 2009Assignee: Lipose CorporationInventor: Robert M. Freund

Publication number: 20080290048Abstract: A device and method thereof for at least partially fractioning or separating fluid from higher density and/or solid particles contained in liquid samples are disclosed. The present invention provides a movable or drivable device having a flow path defined by inner and outer wall surfaces and arranged such that the flow velocity of the liquid sample along the outer wall surface is higher than the flow velocity along the opposite inner wall surface. The flow path provides elements to at least delay the flow of the liquid sample along the outer wall surface. The device is, e.g., suitable for the separation of blood, e.g., of plasma from at least red blood cells, and from red and white blood cells to achieve blood plasma with high purity for analytical reasons.Type: ApplicationFiled: June 2, 2008Publication date: November 27, 2008Applicant: ROCHE DIAGNOSTICS OPERATIONS, INC.Inventors: Rainer Jaeggi, Patrick Griss, Hans-Peter Wahl

Publication number: 20080257836Abstract: A centrifugal separator includes devices for light matter extraction and for heavy matter extraction. Each embodiment provides for a plurality, e.g., two or more stacked or layered chambers, and connected to a central compartment of the chambers is a rotating drive shaft. In the light matter extraction, a central conduit feeds fluid input into the lower chamber. An upper portion of the lower chamber communicates with the lower portion of a mid chamber via a port formed in a plate dividing the chambers. The upper portion of the mid chamber communicates with the lower portion of an upper chamber via a port formed in a plate dividing the chambers. The chambers can be fixably connected to one another. In the heavy matter extraction an initial feed conduit feeds fluid into the upper chamber.Type: ApplicationFiled: April 17, 2007Publication date: October 23, 2008Inventor: Henry J. Laughlin

Publication number: 20080257819Abstract: Separating a multi-phase mixture influent even during excessive flows of specific phases. The dynamic phase separator includes a chamber divided into two regions by an inner wall disposed radially inward relative to an outer wall. A gross separation region is defined between the inner wall and the outer wall, while a fine separation region lies inside an area defined by the inner wall and top of the chamber. Influent to be separated is fed through an inlet into the gross separation region. A plurality of porous disks are mounted to a rotatable shaft and disposed in the fine separation region. The outer and inner walls are separated by a predetermined distance sufficient to allow for adequate rotational velocity of incoming tangential flow of the influent and dwell time sufficient for natural separation of lighter phases from heavier phases within the gross separation region.Type: ApplicationFiled: April 18, 2007Publication date: October 23, 2008Inventor: Robert J. Tarves

Patent number: 7431932Abstract: Reovirus can be used to selectively remove ras-mediated neoplastic cells from a cellular composition. It is of particular interest to purge autographs which may contain neoplastic cells with reovirus before transplanting the autographs back into the recipient, thereby reducing the risk of introducing or reintroducing neoplastic cells into the recipient.Type: GrantFiled: September 26, 2005Date of Patent: October 7, 2008Assignee: Oncolytics Biotech Inc.Inventors: Donald Morris, Bradley G. Thompson, Matthew C. Coffey

Publication number: 20080237151Abstract: A centrifugal force-based microfluidic device in which a sample including particles and a fluid is centrifugally separated such that the separated fluid is quantitatively distributed, and a microfluidic system including the centrifugal force-based microfluidic device are provided. The centrifugal force-based microfluidic device includes a microfluidic structure in which, within a rotatable disc-shaped platform, a sample, including particles and a fluid, is quickly centrifugally separated into the particles and the fluid using the rotation of the disc-shaped platform and the fluid having a certain volume of the separated fluid is discharged by rotation of the disc-shaped platform.Type: ApplicationFiled: March 27, 2008Publication date: October 2, 2008Applicant: Samsung Electronics Co., Ltd.Inventors: Yoon-kyoung Cho, Beom-seok Lee
