  • Drain design for use in a polyurethane composite bathing vessel
    Patent number: 9320394
    Abstract: A bathing vessel has a bottom, and a drain disposed in the bottom adjacent a blended area that is disposed between the side wall and the bottom. The side wall, the bottom wall, and the blended area are made of a first layer of rigid polyurethane material and a second layer of capping material attached to said first layer. A ratio of a density of the polyurethane backing adjacent the drain to a thickness of polyurethane backing is between 1-80:1. The side wall, the blended area and the bottom wall flex to absorb loads adjacent the drain.

  • Apparatus and method for removing materials from a material collection container
    Patent number: 9067727
    Abstract: An apparatus for removing material collected in a material collection container having a floor and at least one substantially vertically extending wall. The apparatus includes a material removal assembly for removing material collected in the material collection container. The material removal assembly includes a first conduit and a second conduit. The first conduit is in telescoping relationship with the second conduit to permit the first conduit to move relative to the second conduit. The first conduit and the second conduit each have a longitudinal axis. The material removal assembly further includes at least one material removal header configured to receive material accumulating on the floor of the material collection container. The material removal assembly is preferably configured to enhance numerous aspects of the sludge removal process.
