  • Patent number: 7060178
    Abstract: A filter-testing fixture holds a single fuel filter and is adjustable to accommodate a range of filter sizes and shapes. The fixture has a base section that defines a water collection reservoir, and the base opens upward toward a housing. Water separated from fuel in the housing thus drains into the reservoir. A fuel inlet conduit passes through the reservoir, one end of the conduit being disposed above the base section. The first, or filter-supporting, adapter is removably attached to this end of the conduit, and both the first adapter and this end are disposed within, the housing. The housing removably and sealingly mates to the base, and a cap assembly likewise removably and sealingly mates to the housing. A second, repositionable, filter-holding adapter is connected to the inner surface of the cap.

  • Patent number: 7052606
    Abstract: A method and apparatus for red blood collection and filtration is provided wherein a red blood cell collection assembly provides for leukoreduction filtration concurrent with or soon after the red blood cell separation and collection procedure. Such procedures involve filtering the separated red blood cells in a diluted state after and/or prior to flushing the filter with storage solution. Storage solution may thus be passed through the leukoreduction filter before, with and/or after the RBCs have been filtered therethrough. The red blood cell collection, filtration and storage assembly is preferably preconnected to a blood component separation disposable assembly, including, for example, a centrifuge vessel and a blood removal/return assembly for removing blood from a donor, passing the blood to the centrifuge vessel for separation of the blood into components for collection and providing for filtration of the separated red blood cell component.

  • Patent number: 7032760
    Abstract: An inline backwash, flushing filter assembly comprising a header assembly, a rotatable valve assembly, and a filter element assembly disposed within a filter housing assembly. In operation, the controller moves the turn knob of the rotatable valve assembly a one-quarter turn which results in the reversal of fluid flow through the assembly to periodically back flush the filter utilizing fluid from the system inlet. Debris removed from the filter element during the backwash process are immediately discharged from the system through a drain port. Simultaneously, the hydraulic shearing mechanism of the backwash process dislodges and drains debris which may have accumulated on the screen and at the bottom of the lower filter assembly during normal filter operations. The controller then returns the filter assembly to filtration operation by a reverse one-quarter turn of the turn knob of the rotatable valve assembly.

  • Patent number: 7033500
    Abstract: This invention is directed to systems and methods for removing lipids from a fluid or from lipid-containing organisms from a fluid, such as plasma. These systems combine a fluid with at least one extraction solvent, which causes the lipids to separate from the fluid or from the lipid-containing organisms. The separated lipids are removed from the fluid. The at least one extraction solvent is removed from the fluid or at least reduced to a concentration enabling the fluid to be administered to a patient without undesirable consequences. Once the fluid has been processed, the fluid may be administered to a patient who donated the fluid or to a different patient for therapy.
