  • Patent number: 6434810
    Abstract: A method and apparatus for high voltage powerline repair which includes temporarily attaching a template to a yoke plate which supports a plurality of powerlines from a tower. The template connects to winch lines which are positioned by the template on opposite sides of the yoke plate directly above a powerline. The winch lines extend from the template to a hand winch and from the hand winch to attachments with the powerline on opposite sides of the yoke plate. These hand winches are concurrently operated to draw the powerline on either side of the yoke plate angularly upward toward the template to break the tension on the powerline.

  • Patent number: 6264142
    Abstract: The improved helicopter anti-icing and deicing system and method includes mounting an airfoil shaped manifold transversely of the helicopter and filling the manifold with anti-icing or deicing fluid which is not under sufficient pressure to spray outwardly from the manifold. Instead, the rear edge of the manifold is provided with small, spaced openings which cause fluid droplets to form along the rear edge of the manifold and to then drop downwardly by gravity. The helicopter is positioned above a power line with the power line extending in the direction of the helicopter longitudinal axis and droplets are caused to exit the manifold as the helicopter flies along the power line.
