  • Patent number: 7129302
    Abstract: Bimetallic catalyst for producing polyethylene resins with a bimodal molecular weight distribution, its preparation and use. The catalyst is obtainable by a process which includes contacting a support material with an organomagnesium component and carbonyl-containing component. The support material so treated is contacted with a non-metallocene transition metal component to obtain a catalyst intermediate, the latter being contacted with an aluminoxane component and a metallocene component, This catalyst may be further activated with, e.g., alkylaluminum cocatalyst, and contacted, under polymerization conditions, with ethylene and optionally one or more comonomers, to produce ethylene homo- or copolymers with a bimodal molecular weight distribution and improved resin swell properties in a single reactor. These ethylene polymers are particularly suitable for blow molding applications.

  • Publication number: 20060110117
    Abstract: A cable management system includes an equipment system, and at least one patch panel having a connectivity interface. The connectivity interface is configured to connect with at least one cable extending from the equipment system. The cable management system also includes a manifold configured to be located between the equipment system and the patch panel. The manifold includes an inlet and an outlet, and the manifold is configured to direct the at least one cable from the equipment system to the connectivity interface.

  • Patent number: 6024318
    Abstract: A ice fishing apparatus which is foldable into a compact storage position. The inventive device includes a U-shaped member, a pair of side legs pivotally attached to opposite sides of the U-shaped member, a rear leg pivotally attached to the rear portion of the U-shaped member, a reel rotatably attached within the U-shaped member by a shaft, and a winged nut threadably attached to the end of the shaft for allowing adjustment of the resistance placed upon the reel. The user positions the invention about the ice hole to insure proper gripping of the ice surface around the ice hole. When finished utilizing the invention, the user simply folds the legs toward one another to create a narrow structure for storage within a vehicle or other structure.
