  • Patent number: 6676422
    Abstract: The specification discloses a cap for sealing the terminal end of a power cord, such as a marine power cord, against dirt and moisture. The specification also discloses that the cap actively prevents corrosion of the electrical contacts covered by the cap by the inclusion of corrosion-inhibiting compounds dispersed within the plastic of the cap. The corrosion-inhibiting compound are released in gaseous form within the cap, thereby inhibiting corrosion of the electrical contacts.

  • Patent number: 6585577
    Abstract: This invention relates to a vibrating abrasive cleaning apparatus and method which is powered by a hydraulic drive motor mounted to a square tubing fame which is housed within an enclosure that is vibrated by an eccentric shaft assembly directly coupled to the hydraulic drive motor and square tubing frame. The container assembly is mounted on the rigid square tubing frame, on one side by compression springs, on the opposite side by tension springs. The compression springs and tension springs have a different spring rate which produces better rolling of the media and therefore, faster parts circulation and cleaning. To further give flexibility to the cleaning process the hydraulic power supply is equipped with the variable volume piston pump to give infinite speed settings.

  • Patent number: 5123547
    Abstract: The invention concerns equipment for storing and shipping pipes with several superposed pipe supports. To simplify manufacture and lower its costs and further to achieve versatility, the pipe supports (5) each comprise a long, integrated molding (120) with several cylindrical clearances (122, 124) present on two opposite sides, for several pipes, or several short assembled molded segments (2) with at least one cylindrical clearance (6,8) for the pipes, on opposite sides. The integral molding (120) and the molded parts (2) are provided with a central duct (10) extending between and transverse to the bilateral clearances and passing through the molding or the molded segments. The integral molded segments are plugged in geometrically locking manner onto a strip or a hollow shaped section (4). The intrgral molded segment (120) preferably is attached by injection molding to the hollow shaped section.
