  • Patent number: 7703235
    Abstract: A hydrodynamic fishing device includes a plate that changes attitude as the plate passes through a body of water. A plate positioning controller is pivotally mounted to the plate and is indexable relative to the plate by direct application of manual force so as to assume a plurality of predetermined adjustment positions. The adjustment positions establish different paths of travel of the plate as the plate passes through a body of water.

  • Patent number: 5938469
    Abstract: A coupling system suitable for use with a transmission cable is described. The system includes a tongue and a connector housing coupled to a cinch. The connector housing is generally cylindrical. The connector housing defines an open bore adapted to receive the cable and has an aperture at one end of the housing. The cinch is attached to the connector housing and has two walls that diverge from each other and the housing aperture. The tongue is adapted to wedge the cable between the cinch walls and outer peripheral surface of the tongue.
