  • Patent number: 11351428
    Abstract: Embodiments provide a lacrosse head with an enhanced pocket channel and sweet spot. The head includes first and second tabs protruding rearwardly from the rearward face of the transverse wall, with the transverse wall defining at least one inner pocket member opening disposed between first and second outer pocket member openings on the respective tabs. A first rearwardmost pocket-supporting edge of the first tab, a second rearwardmost pocket-supporting edge of the at least one inner pocket member opening, and a third rearwardmost pocket-supporting edge of the second tab may lie on an arc shape that is more curved than the curved shape of the transverse wall, to provide a cylindrically-shaped pocket channel. Each sidewall may have a rearward lower edge portion that extends generally parallel to the horizontal centerline and an intermediate lower edge portion that rapidly descends to a lowest point, to enhance the sweet spot of the head.

  • Patent number: 7201843
    Abstract: The new design has three primary features: (1) a rectangular collar having a centrally located circular cutout with sewn loops formed on the outer edges of the collar; (2) a filter bag having top edges attached to the rectangular collar along the periphery of the circular cutout so that the bag is inserted within the cutout and drops below the level of the collar; and (3) a heavy gauge steel wire inserted within the sewn loops of the rectangular collar forming a structural frame along the periphery of the rectangular collar. The structural frame is preferably formed with overlapping portions coupled together with a retaining means. The overlapping portions are slidably moved relative to one another to change the first and/or second dimension of the frame so that the filter can fit within catch basins openings of various measurements.

  • Patent number: 7128771
    Abstract: A filter retaining system formed from multiple filter retaining frames is disclosed. Each of the frames is formed from either a female type extrusion or a combination of male and female type extrusions. Specifically, each frame has either a tongue or a groove which is engageable into a corresponding groove or tongue of an adjacent frame. The tongue and groove engagement provides added rigidity to the retaining system, as well as preventing air from bypassing the filters retained within each frame.

  • Patent number: 7073670
    Abstract: A filter element for hydrocarbon emissions in, e.g., marine diesel engine applications, comprises a wound mat received within a filter bag. An annular end cap is bonded to one end of the wound mat, and is sealed around its periphery to a bag ring at the open end of the bag. The bag ring is then received and retained in a seat ring in the housing. The exhaust gas stream from the engine is directed through an opening in the end cap and through the wound mat and bag for removal of hydrocarbons and contaminants.

  • Patent number: 7063783
    Abstract: A conduit has a first end and interior and exterior surfaces extending downstream from the first end. A strainer has a first end and a second end. An upstream portion of the strainer is positioned engaging a projection on the interior surface of the conduit to resist downstream shifting of the strainer. A strainer body extends at least partially downstream of the upstream portion. The apparatus may be used as a strainer/coupler and may be used to filter water in a chiller apparatus.

  • Patent number: 6929742
    Abstract: In the case of a fine filter for a fuel feed unit of a motor vehicle, a filter element has at least two sections which surround the fuel feed unit concentrically. In the fitted state of the fine filter, the sections are fastened to the fuel feed unit and to a surge chamber. The filter element has proven particularly cost-effective and enables the use of a particularly small mesh width while requiring little space.

  • Patent number: 6872466
    Abstract: A method of plugging an area of damaged mesh in a sifting screen. The method is applicable to screens in which woven wire mesh is stretched, tensioned and secured over a supporting frame containing a plurality of windows and in which local damage to the mesh is in an area of the mesh which overlies one of the windows. The method has the steps of inserting into the window a device which is a close fit therein, and securing the device in the window so as to completely cover the area of damaged mesh. The device may be a former having stretched thereacross and secured thereto mesh similar to that stretched across the window in question, or simply a plate or block. The device may be secured in place by a force or interference fit, mechanical means, or adhesive, or the device may be resiliently deformable to allow it to be pushed past a projection in the window, so as to snap fit the device in place.
