  • Patent number: 8974665
    Abstract: A welded wire mesh is rolled into an elongated tubular wire frame, and sizing rings surround the tubular wire frame to maintain the tubular frame with a predetermined diameter. The wire frame is partially covered with a sediment filter fabric attached by wire clips, and an end portion of the tubular frame is inserted into an inlet portion of an installed storm water pipe. A collar member includes a wire collar frame secured to the tubular wire frame and is covered by a flexible filter material to filter storm water flowing between the tubular frame and the water pipe and to form a stop which prevents the tubular frame from moving further into the pipe. A top portion of the tubular wire frame is uncovered by filter fabric to define an overflow opening for storm water with very light sediment to flow into the storm water pipe.

  • Publication number: 20110253641
    Abstract: A filter sleeve is fabricated from a variety of media selected to preferentially remove particulates and specific contaminants from water or other liquids. The layers of the filter sleeve may be configured to remove 1-micron particulates, while another layer or layers may be configured to remove a range of petroleum hydrocarbons, fats, oils, and greases, while yet another layer may be configured to remove metals, and yet another layer could be configured to remove bacteria, algae, mold, and fungus. Filter sleeves that are configured to remove different particulate sizes and contaminants can be used simultaneously by placing the filter sleeves inside one another to accrue the capabilities of several individual filter sleeves as one unit. The filter sleeve can be used to remove particulates and hydrocarbons from waste water accumulated in underground vaults, enabling such waste water to be discharged directly into the ambient environment.

  • Patent number: 6395167
    Abstract: A whirlpool bath has a combination suction fixture and disposable filter. The suction fixture is a plastic semi-cylindrical housing attachable to the tub. A removable faceplate is reinforced and resistant to body and hair entrapment. The disposable filter is fibrous having a porous core, wherein the porous core has a series of holes and/or slots graduating in size from small at the outlet end to large at the remote end. The filter, sloped floor of the housing and drain slots provide for low water retention during shutdown.

  • Patent number: 6371307
    Abstract: In accordance with this invention, an improved filter resembling an envelope is disclosed. The filter envelope for the filter frame element includes an enclosure, the enclosure being constructed from planar first and second filter paper members lying atop one another. The first and second filter paper members each have a lateral, medial, base, and top sides, the lateral, medial, and base sides being connected to each other, respectively, to define the enclosure. The top side of the first member is not connected to the top side of the second member so as to define an opening in the enclosure to receive the frame. A closure is formed from a planar third filter paper member which is connected to a portion of the enclosure being proximate to the opening. The third filter paper member is movable between a first position and a second position, the second position being suited to close the opening.

  • Patent number: 6220454
    Abstract: A compact, high capacity in-tank fuel filter defines a large surface area while simultaneously occupying a relatively small space and defining a small footprint. The filter comprises a body of filtration media and an outlet fitting which is integrally molded to the filtration media and provides communication from the interior of the filter to an associated fuel pump to which it is typically mounted. The filtration media of the body is folded upon itself in a multiple accordion fold configuration and sealed along the non-folded edges. The resulting surface area to size (footprint) ratio provides improved flow capacity, reduced pressure drop and extended service life.

  • Patent number: 6165357
    Abstract: The roof drain cover of the present invention comprises a dome-shaped strainer adapted to sit over a roof drain pipe, a bolt going through the strainer at the center thereof, protruding from the same to downwardly extend within the pipe and having a bolt head accessible from above the strainer and abutting the same, an anchor and a disc-like stop. The anchor includes a nut screwed on the bolt, a pair of wings pivoted on the nut and foldable along the bolt and towards the strainer against the bias of a spring carried by the nut. The tips of the wings are adapted to frictionally engage the inner face of the pipe under the bias of the spring to prevent rotation of the nut when the bolt is screwed within the strainer. The disc-like stop is secured to the bolt above the nut and engages the wings to cause firm anchoring engagement of the wing tips with the pipe when the stop approaches the nut during screwing of the bolt.

  • Patent number: 6035580
    Abstract: A self-priming drain guard siphon insertable into the opening of any reservoir drain subjected to accumulation of fluid transported debris comprising an outer shell (17) enclosing an inner priming chamber (20) held upright on the bottom of a reservoir by support tabs (18). Priming chamber (20) is comprised of inlet openings (22), a horizontal chamber (20a), a vertical chamber (20b), and an outlet opening (24). Inlet openings (22) are each positioned above and between adjacent support tabs (18) and vertical chamber (20b) at an elevation slightly higher than the bottom of a reservoir. Inlet openings (22) are cumulatively sized to approximate flow capacity of horizontal chamber (20a) and are positioned on the underside of horizontal chamber 20a to prevent lateral passage and direct contact with median sized debris. Horizontal chamber 20a is sized to approximate the flow capacity of vertical chamber 20b.

  • Patent number: 5885450
    Abstract: A water purifier includes a quick connect connector in a port that receives a tube that carries the water. The tube is received along the axis of the port in a first reference direction along the axis. The connector is assembled by inserting, in sequence, a support ring, an O-ring, and a plug into the port along the axis, but in a direction opposite the first direction. The plug is held in place by adhesive or conventional welding. To complete the assembly, a collet is inserted into the port along the axis and in the first direction. A tube is then connected to the water purifier by urging the tube through the collet, along the axis, and in the first direction. The tube is gripped by the collet, supported by the support ring, sealed by the O-ring, and stopped against the plug.

  • Patent number: 5865996
    Abstract: A water purifier includes a port having a collet, an O-ring seal, and a support between the collet and the seal. The collet axially receives a tube for water passage. The support limits radial movement of the tube off the axis. The support has an L-shaped cross section having a radial leg that seats the O-ring, and an axial leg. Water purifiers are often installed in confined spaces near mechanical equipment. Conventional water purifiers installed with sharp bends in influent and effluent water tubes and exposed to equipment vibration conducted by the tubes often exhibit weeping at the port. In an embodiment of the present invention, weeping is eliminated by maintaining axial relation between the tube, the seal, and the collet.

  • Patent number: 5732621
    Abstract: A filter sleeve (26) surrounds a rod-shaped, flexible drain core with flow paths for removing a pressed-out liquid from the pressing chamber of a press. For mounting one or both ends of the filter sleeve (26) and the drain core on the press, a rubber or elastically deformable shaped element (29) with a ring-like bead (22) is firmly connected with the filter sleeve (26) at its end. The shaped element (29) inseparably penetrates the fabric of the filter sleeve (26) because of an elastomer coating, and the bead (22) is automatically positioned in a groove (24) of a support body (23) because of its previous stretching.
