  • Patent number: 9527701
    Abstract: A dual drive winch having a drive assembly having a first shaft that is selectively movable between a first engaged position and a first disengaged position, and a second shaft that is selectively movable between a second engaged position and a second disengaged position. When the first shaft is in the first engaged position and the second shaft is in the second engaged position simultaneously, rotation of either the first shaft or the second shaft will, through a coupling mechanism, cause rotation of the other of the first shaft and the second shaft.
    Type: Grant

  • Patent number: 8254516
    Abstract: An outer filter removal tool for a boiling water reactor control rod drive that uses a mechanical advantage obtained through the use of lead screw threads to pull the outer filter off of the control rod drive. Fingers on the tool are closed around the upper flange of the outer filter by sliding a collar over the outwardly biased fingers. A shaft extending through the tool is rotated which in turn extends a push plate against the control rod drive index tube causing the fingers to pull against the upper flange on the outer filter until the filter is freed from the control rod drive. The tool will hold the filter in place until affirmatively released for proper disposal.

  • Patent number: 6253512
    Abstract: A method of applying tiles to a roof, the tiles being of at least two different appearances, includes establishing a collection of pattern units, each pattern unit representing an arrangement of a plurality of tiles formed into a specific pattern, the specific pattern of each pattern unit being different from the specific pattern of every other pattern unit in the collection of pattern units. Each pattern unit includes representations of tiles of at least two different appearances, such as different colors. Tiles are applied according to a first one of the pattern units, to a first portion of the roof. Tiles are applied according to one of the pattern units, to a second portion of the roof that abuts the first portion of the roof. Additional tiles are applied to additional portions of the roof, the tiles being applied to each additional portion of the roof according to one of the pattern units, with each additional portion of the roof abutting a previously applied portion of the roof.
