  • Patent number: 7909990
    Abstract: A filter device is made up of: a filter portion having a fluid outlet at its axis, and a fluid inlet in a position away from the axis, in which a fluid containing particles is supplied at a predetermined flow speed from the fluid inlet to cause a swirling, particles are moved outward in a centrifugal state and the fluid from which the particles are separated is discharged from the fluid outlet, and the particles separated by slowing down the swirling are allowed to sink; and a settlement portion in which the particles that settle in the filter portion are allowed to settle. Thus, a fluid containing particles is supplied at a predetermined flow speed to cause swirling, the particles are separated by a centrifugal force caused by the swirling and allowed to sink and settle, and the fluid from which the particles are separated is discharged. A large amount of particles can be allowed to settle and be reliably removed in a short time with this small-sized and simple device.

    Abstract: A lubricant reclamation system having a moisture absorbent cartridge (140). The cartridge (140) is fabricated placing a Superabsorbant Polymer (SAP) (142) within a boundary of polyester mesh (143). Moisture is extracted from a lubricant or other fluid and absorbed by the SAP. The moisture latent SAP bonds to the polyester mesh (143), potentially turning into a gel. A layer of polypropylene sorbent (144) is placed about the exterior of the boundary material (143), ensuring any moisture remains exterior to the sorbent layer (144). A resin layer can optionally be placed within a fluid flow following the discharge from polypropylene sorbent extracting aerosol from within the lubricant and as a barrier of detrimental ions with an exchange of beneficial ions. The entire cartridge can be placed within an enclosure or pouch body (162). The body (162) is designed to expand, accommodating a resultant increase in SAP volume. The cartridges can be integrated into filters comprising commonly known filtration elements.

  • Patent number: 7699984
    Abstract: A hydrodynamic treatment device comprises a vessel (2) within which is disposed an inner partition (24). The inner partition (24) divides the interior of the vessel (2) into outer and inner regions (22, 28). Flow enters the vessel (2) through a tangentially oriented inlet (14) and establishes a complex circulating flow within the vessel (2). Settleable solids migrate to the bottom of the vessel (2) and are deposited in a sump (20) through a solids outlet opening (18). Flow enters the inner region (28) through apertures (34) in the inner partition (24), and is discharged through an outlet duct (8). The inner region (28) is closed at its lower end by a frusto-conical, downwardly diverging lower wall (30) which projects outwardly from a central cylindrical wall (26).

  • Patent number: 7632397
    Abstract: The present invention relates to an integrated portable water purifier for purifying water, by filtration through adsorption media to remove harmful chemicals followed by ultraviolet treatment to disinfect the water. The water purifier effectively removes the contaminants found in drinking water. The integrated portable water purifier includes a water chamber (1) for receiving water to be purified and a treated water chamber (2) for receiving treated water through a filter cartridge (20). The water purifier is provided with a microprocessor based controller (6) for controlling the operation of the purification system. A UV lamp (8) is provided in the treated water chamber (2) for microbiological treatment of the filtered water in the treated water chamber (2) and a sensor (7) for sensing the conductivity of the treated water and the level of the water in the treated water chamber (2). A power source (18) is provided for supplying power to the system.
