  • Patent number: 6494325
    Abstract: A toilet water-line filter (10) that is designed to protect a toilet's fill valve (62) from the intrusion of potentially damaging debris such as rocks, vegetation, etc. The filter (10) is comprised of a housing (12) and an internal filter (34) which consists of a mesh staining element (36). The filter (10) is attached between the toilet's fill valve (62) and a typical, flexible, water line (66). Debris that would normally pass into the fill valve (62) becomes trapped in the mesh staining element (36), from where the debris is easily removed.

  • Patent number: 6482321
    Abstract: A suction head is provided for the end of a fuel hose in a fuel tank of a portable implement. The suction head comprises a cup-shaped housing of polymeric material that is closed off by a cap. Provided on the cap is a connector for the end of the fuel hose. The outer surface of the housing is provided with window-like cutouts that are covered by a filter mesh. In order also with narrow, fragmented tank housings to ensure an immersion of the suction head into the fuel in every operating position, a rod-shaped weight member is disposed in the center of the housing. This weight member extends from the base of the housing to the cap, with a first end of the weight member being held on the base and a second end being held on the cap.

  • Patent number: 6447680
    Abstract: A filter for filtering particulate matter from liquids adapted to be received in a filter casing having a casing wall and an outlet is provided. The filter includes a filter element having a plurality of openings therein for filtering particulate matter while allowing liquids to pass therethrough, the filter element comprising a first section located proximate to the outlet and a second section adjacent to the first section. The filter element is receivable in the casing and is spaced apart therefrom such that the filter element and the casing wall define a space therebetween. A seal separates the first and second sections and prevents the flow of liquid therearound in the space. The seal is located below the outlet. A lower end member closes a lower end of the filter element, the lower end member preventing the flow of unfiltered liquid and particulate matter into the filter element.

  • 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.
