  • Patent number: 8298420
    Abstract: A drainless reverse osmosis (RO) water purification system provides relatively pure water for on-demand dispensing, while recycling brine to a domestic hot water system. The drainless purification system includes a pre-filter catalyst cartridge for removing chlorine-based contaminants from a tap water supply upstream from an RO membrane. The catalyst is regularly refreshed by a high through-flow of water to a conventional cold water dispense faucet, thereby significantly prolonging the service life of the RO membrane. The RO membrane is incorporated into a multi-cartridge unit adapted for facilitated slide-out removal and replacement as needed. A control valve recycles brine from the RO membrane to the hot water system during pure water production, and recirculates tap water through the RO membrane when a pure water reservoir is substantially filled. The multi-cartridge unit may further include an air filtration system for providing a flow of filtered air.

  • Publication number: 20120165176
    Abstract: This invention provides a blood processing filter including a flexible container having an inlet and an outlet for blood, and a sheet-like filter member arranged so as to divide the inside of the flexible container into one side and another side. An annular seal part is formed at which an entire circumference that is adjacent to a peripheral portion of the filter member is integrally sealed to the flexible container. The blood processing filter is retained in a curved shape that curves as viewed from a predetermined one direction that is orthogonal to the thickness direction by the rigidity of the seal part.

  • Patent number: 8202337
    Abstract: Embodiments of the invention generally provide a containment system having integrated bubble tight-dampers. In another embodiment, the containment system includes an integral auto-scan mechanism disposed in the housing of the containment system so that a filter element, disposed in the housing, may be leak tested without accessing the interior of the housing. In yet another embodiment, a method for testing a filter disposed in a containment system includes challenging an upstream side of a filter element disposed in a housing of the containment system with a test aerosol, and automatically moving a probe disposed within the housing to obtain samples for leak testing.

  • Patent number: 8187458
    Abstract: An oil filter assembly is disclosed for a machine, such as an internal combustion engine, that has an oil output port and an oil input port. A mounting plate is fixed with an outer enclosure and is adapted for securing to the machine. The mounting plate is further adapted to conduct oil from the machine into a peripheral portion of the outer enclosure, and then returning oil from a central portion of the outer enclosure back to the machine. Oil may pass from the peripheral portion to the central portion through a primary filter having a first porosity. A pressure-actuated valve is fixed fluidly between the peripheral portion and central portion of the outer enclosure. Oil may pass through the pressure-actuated valve only when an oil pressure differential between the peripheral portion and the central portion of the outer enclosure exceeds a predetermined threshold pressure.

  • Publication number: 20120097416
    Abstract: The present invention provides a system and method for transmitting information between a device within a housing to a second device, preferably a test or monitoring unit, outside of the housing. There are numerous issues associated with transferring information from within a sealed housing to an external device. In some cases, the use of wires inside the housing may be impractical, due to internal conditions, such as fluid flow, pressure or temperature. In one embodiment, the antenna of the external RF reading device is electrically connected to the dome of the housing. In another embodiment, the device within the housing is electrically connected to a housing component. In another embodiment, the gasket is used to pass information from within the housing to an external device.

  • Patent number: 8157997
    Abstract: A canister filter system includes a base, a canister attachable to the base, and positioned inside the canister a filter element having filter media. A drain engages and forms a seal with the filter element in a closed position. In an open position, the drain allows fluid to be removed from the canister. Because the drain is engaged to and forms a seal with the filter element in the closed position, the drain cannot be closed unless a filter element is present inside the canister. This prevents accidental or intentional use of the filter system without a filter element in place.

    Abstract: A filter assembly including first and second mating parts and a seal received in a groove of the first mating part. The seal includes a main body and a resiliently flexible, sloping skirt that extends from one side of the main body to a distal end spaced from the main body. The seal is sized so that the resiliently flexible skirt normally extends out of the groove of the first mating part when the skirt is not biased towards the main body. When the first mating part is slid against the second mating part, the second mating part causes the distal end of skirt of the seal to be biased into the groove and towards the main body of the seal.
