Abstract: A cross-arm for a utility pole, the cross-arm includes an elongated, hollow bar member molded from synthetic material, such as a sheet-molding compound of polyester glass-reinforced plastic. The elongated bar member has a first end, a second end opposite the first end, a plurality of through-holes for mounting the cross-arm to a utility pole with fasteners and for mounting electrical line support insulators. A groove extends from the first end to the second end of the elongated bar member, for receiving a wire or cable. A recess is provided in a wall of the elongated, hollow bar member which substantially conforms a section of the wall to the utility pole.

Abstract: Radiant heat deflection system for use when a person is subjected to high temperature conditions during athletic activity. The heat deflection system is capable of deflecting radiant away from the wearer's head or body, thereby reducing the amount of heat absorbed by the person. The invention also relates to heat retaining inserts and apparatus for use during athletic activity, to increase heat retention in cold temperatures.

Abstract: A bumper for limiting the limiting the mobility of a wheeled device. The bumper is an elongated member having a base wall and an elastically resilient wheel engagement wall coupled to the base wall. The wheel engagement wall includes an outer surface and an inner surface, one of which includes reliefs for aiding the wall to conform to and stop the rolling action of a wheel of a wheeled device when impacted thereby. The energy stored in the engagement wall when impacted by the wheel of the wheeled device returns the engagement wall to its original shape thereby pushing the wheel of the wheeled device away from the elongated member. A bumper system may be fabricated by connecting two or more of the bumpers together in a desired configuration using adjustable, straight, or bent connectors.

Abstract: A method for fabricating a triphasic composite such as a WC/Co/diamond composite with a high volume fraction of diamond in a WC/Co matrix. The method involves sintering of a WC/Co powder compact to develop a porous preform, which displays some rigidity and strength, infiltrating the porous preform with a controlled distribution of carbon, and high pressure/high temperature treatment of the carbon-containing WC/Co preform to transform the carbon to diamond. The distribution of diamond in the composite can be functionally graded to provide a WC/Co core and a diamond-enriched surface, wherein all three phases form an interconnected structure in three dimensions. Such a tricontinuous structure combines high strength and toughness with superior wear resistance, making it attractive for applications in machine tools and drill bits.
