  • Patent number: 10531822
    Abstract: An independent blood filter device depends on flow geometry to deliver blood serum or plasma free of detrimental levels of hemoglobin. It depends critically on an upstream flow rate or pressure differential limiting control element or device that limits the rate of change of pressure differential across the filter element. Pre-evacuated versions can be used to simultaneously draw blood from a living being and provide pressure differential across the filter element between an evacuated collector and a supply end open to atmosphere. A unit pressurized by hand motion employs the external shape of a partially filled blood collection tube as a piston to produce pressure in advance of the control element or device to create the pressure differential across the filter element to a collector vented to atmosphere. The control element or device is disclosed in numerous forms, including specially sized flow constrictions and compliant arrangements.

  • Patent number: 8640881
    Abstract: The invention relates to a screen changer in a system that processes flowable plastic. The screen changer includes an element, such as a portafilter, that is movable between two positions; two hydraulic pumps that effect position change of the screen changer; and a motor that operates both pumps. One pump provides greater flow volume and the other provides a lower flow volume, but with greater pressure. A non-return valve in the supply line to the hydraulic cylinder controls flow to the cylinder that moves the movable element between positions. The volume pump is used to move the movable element when resistance to movement of the screen is low and the high-pressure pump to move the element when resistance is high. The non-return valve selectively enables or interrupts flow from the pumps to the hydraulic cylinder. The screen changer allows use of a non-pressurized hydraulic fluid reservoir.

  • Patent number: 8628671
    Abstract: A reservoir for use with a blood collection system includes a housing, a pre-filter, and a spring mechanism. The housing defines a cavity and has an inlet for receiving fluid from a source. The pre-filter is located within the cavity, removes particulates contained within the fluid, and allows the fluid to pass through the pre-filter. The spring mechanism is connected to the pre-filter and allows the pre-filter to travel within the cavity as the pre-filter collects particulates.

  • Publication number: 20130277319
    Abstract: A screw press has a cylindrical screening section mounted to a frame. The screening section is able to rotate but can be prevented from rotating. A sprayer system is operable to spray water on the screening section. In a cleaning process, the screening section is rotated while water is sprayed against it. Optionally, the power required to rotate the screen may be provided by an auger drive mechanism. The screening section may have openings sized to retain flocculated solids. The screw press may be used to thicken a sludge from a waste water treatment plant.

    Abstract: An apparatus (25) for use in screening a liquid and solids mixture feed (2) comprises a conduit (18), including a screening portion (22) that is formed and arranged to divide a liquid and solids mixture feed flowing through the conduit. The feed (2) is divided into a first, cleaned stream (C1) comprising liquid and solid particles of below a selected size limit, and a second, concentrated, stream (24) comprising liquid, and particles above the selected size limit. The apparatus (25) may be a stand alone module, part of a system with other solids and liquids separating equipment or an integral part of a solids and liquid separator such as a shale shaker. Methods of using the apparatus (25) are also described.

  • Publication number: 20130171312
    Abstract: Processing of a bulk liquid including particles, including use of a rotating strainer surface with openings disposed on a circumference thereof, the openings allowing an extracted liquid in the bulk liquid to pass through the strainer surface while preventing particles from passing through the strainer surface, such that a concentration of particles in the extracted liquid is less than in the bulk liquid; an extracted liquid outflow port which outputs the extracted liquid from an interior region of the rotating strainer surface; and a motor configured to rotate the strainer surface at a speed sufficient to generate a centrifugal force or turbulence at the openings sufficient to prevent the particles from clogging the openings, wherein the strainer surface is rotated and the extracted liquid is output through the extracted liquid outflow port when the strainer surface is fully submerged in the bulk liquid.

  • Patent number: 8414765
    Abstract: A system for processing cells is disclosed. The system may include a container having an inner wall, a plunger adapted to be slidably positioned within the container, at least one inlet port through which a fluid can enter the container, at least one outlet port through which a fluid can exit the container, at least one effluent port through which an effluent can exit the container, a first check valve in fluid connection with the inlet port and a second check valve in fluid connection with the effluent port. The plunger may include a filter that allows fluid to pass therethrough but prevents cells from passing therethrough. Rearward motion of the plunger may be adapted to draw fluid into the system via the inlet port and forward motion of the plunger may be adapted to force effluent out of the system via the effluent port.

  • Patent number: 8383066
    Abstract: A filter vial and piston are provided where the vial has a cylindrical wall with a closed bottom and open top and with the hollow, tubular piston therein. The piston has a distal end covered by a cup having a proximal cup seal extending outward to engage the walls of the vial to form a fluid tight seal with the vial during use. The distal end of the piston has a piston flange extending outwardly and located adjacent a recess in the piston so the cup forms a snap fit over the piston flange and extends into the recess. The piston flange causes the cup to bulge sufficiently outward to form a fluid tight seal with the vial during use. A filter is placed in the bottom of the cup and abuts an inwardly extending lip on the cup. The filter is held against the lip by a piston support at the distal end of the piston. A cup support at a distal end of the cup also helps support the filter.
