The systems and methods hold the blood collection tube a predetermined radial distance from the incident light source where a linear relationship exists between sensed reflected light measured by the optical sensor and red blood cell hematocrit in a range of at least 10 to 90. The systems and methods make possible accurate red blood sensing without use of special optical cuvettes, mirrors, or focusing lenses. The systems and methods also make possible the use of standard transparent plastic tubing, without reliance upon special optical cuvettes.Type: ApplicationFiled: May 28, 2002Publication date: April 17, 2003Applicant: Baxter International Inc.Inventors: Matthew R.

Patent number: 6533935Abstract: A drain valve for a fuel filter water separator for an internal combustion engine has a first port mating with the vent opening of the separator, a second port mating with the drain opening of the separator, and a third port. The drain valve is actuatable between a closed position blocking communication of the first port with the third port and blocking communication of the second port with the third port, and an open position providing communication of the first port with the third port and providing communication of the second port with the third port. If the valve is actuated to the open position when the engine is off, collected water and vent air each flow through the third port but in opposite directions. If the drain valve is actuated while the engine is running, pressurized fuel spray from the vent opening and collected water from the drain opening of the separator each flow through the third port in the same direction.Type: GrantFiled: November 30, 2001Date of Patent: March 18, 2003Assignee: Fleet Guard, Inc.Inventors: Paul D. Miller, John Arnett, Melvin D. McCormick

Publication number: 20020185432Abstract: A removable conformal liner for a centrifuge container is described. The liner has a flexible or semi-rigid body with an opening for introducing a sample. When the liner is inserted into an internal cavity of a centrifuge container, the body of the liner conforms to the interior cavity. The liner body may be made of a material that is sufficiently resilient to allow a reversible deformation of the body by folding, twisting, collapsing, rolling, or pleating. Also disclosed is a centrifuge container assembly, including a container suitable for centrifuging and a removable liner with a flexible or semi-rigid body placed into the container. The centrifuge container assembly of this invention may also have retaining-means for retaining the liner in a fixed position within the container. Also provided by the present invention is a method for separating solids from suspensions by centrifugation.Type: ApplicationFiled: August 5, 2002Publication date: December 12, 2002Applicant: Beckman Coulter, Inc.Inventors: Melvin Dorin, Patrick Q.

Patent number: 6454104Abstract: A clarifier in a sewage treatment process includes efficient scum removal within the influent well, with discharge of the scum and other floatables as a dedicated waste stream separate from return activated sludge and biological scum collected in the clarifier. In one embodiment the scum removal system has an inclined scum ramp at the leading edge of each of two scum removal troughs, with a forward edge below the liquid surface. The scum troughs pass through an arc of rotation, building up scum, which accumulates and is pushed forward by the scum ramp. At least once per revolution, the moving scum ramp approaches a stationary scum surface blade that extends partially under the liquid surface and provides a barrier to the forwardly pushed scum. This blade contacts and slides up the ramp, sweeping the scum up the ramp and into the scum trough.Type: GrantFiled: May 23, 2001Date of Patent: September 24, 2002Assignee: Enviroquip, Inc.Inventors: Elena Bailey, Robert Shurtleff

Patent number: 6402959Abstract: A fluid distributing-collecting process using a device for bringing fluids and solids into contact comprises several distributor plates and several panels for mixing, distributing or extracting fluids. The system for practicing the method includes at least one level one chamber in connection with the outside of said device with at least one hose and, at least one level two chamber that is linked with the level one chamber and that comprises one or more connecting hoses of a selected length that are arranged in at least one zone. The zone is identified relative to an angle &agr; relative to a radius of a plate and corresponds to a given angle sector, whereby hose lengths, angle &agr; and the angle sector are selected in accordance with the process so that injected fluid arrives approximately at the same time on all of the panels of the same plate. This process is used for separation of paraxylene in a simulated moving bed.Type: GrantFiled: October 19, 2000Date of Patent: June 11, 2002Assignee: Institut Francais du PetroleInventors: Jean-Paul Dessapt, Pascal Duchene, Bertrand Szymkowiak, Gilles Ferschneider, Olivier Callebert

Patent number: RE40051Abstract: A self-venting drain valve is rotatably and slidably mounted to a filter assembly through an internally threaded base. The drain valve comprises a homogenously formed one-piece unitary valve body including a tubular valve stem portion and a valve knob portion. The valve stem portion includes a wall member defining an internal passageway provided with axially extending air vent openings through which ambient air can enter a filter housing through the internal passageway, and drain holes through which water is drained from the filter housing and the internal passageway. The air vent openings are formed through an upper portion of the wall member and are open to a top edge thereof, while the drain holes are formed through the lower portion of the wall member. The liquid drains from the filter housing through the internal passageway and the drain holes, then exits into the valve knob portion.Type: GrantFiled: March 18, 2004Date of Patent: February 12, 2008Assignee: Wix Filtration Corp LLCInventors: Willie L.
