  • Publication number: 20140069333
    Abstract: A method including placing a body defining an undifferentiated lumen therein over a portion of a fixture coupled to a building structure, the body having at least one opening that can be expanded from a contracted state and that is biased toward the contracted state, the placing including applying an expansion force to the opening; conforming the body to a shape of the fixture at a contact portion where the fixture contacts the structure by releasing the expansion force; and treating the structure.
    Type: Application

  • Patent number: 8287960
    Abstract: A shield, which covers exposed surfaces of objects/fixtures attached to, but not limited to, walls, floors, ceilings, doors, or windows preventing coating material or dust particles from getting into or onto objects/fixtures. In construction or remodeling particle or coating material such as, but not limited to, dust, paint or plaster can enter into or get onto objects/fixtures. A pliable elastic type material further comprising a container or sleeve like structure with a minimal of one opening placed over the fixture. The elastic type container or sleeve comes in various sizes and can adapt to the different size and shapes of fixtures. The elastic material stretched over the fixture, conforming to the shape of the fixture or fixture's base, creating a tight thin seal around the perimeter edges. The thin membrane creates a very close tight seal allowing coating material to be very closely administered to the surface area next to the fixture without entering or getting onto the fixture.

  • Patent number: 5275740
    Abstract: A method for controlling the filling of a filter press with slurry according to a preferred embodiment of the present invention includes the sequentially executed steps of: gradually increasing the pressure of the slurry supplied to thee press until the slurry pressure reaches an upper pressure limit; recording a trigger point in time at which the slurry pressure reaches the upper pressure limit; and determining whether the slurry pressure subsequently falls below a lower pressure limit within a predetermined period of time commencing at the trigger point. If the slurry pressure does fall below the lower pressure limit within the predetermined period of time, then the above-listed sequence of steps is repeated until the slurry pressure fails to fall below the lower pressure limit within the predetermined period of time, thereby indicating that the press is full and terminating the process.
