Abstract: A golf ball retriever system comprising a unitary retriever component which includes an enlarged first cylinder and a smaller second cylinder formed of a generally rigid elastomeric material molded integrally. The second cylinder has diametrically opposed axial slots which are adapted to be received over the reception area of the handle end of the putter. The first cylinder has an opened free end remote from the second cylinder and a diameter greater than that of a standard golf ball. A generally circular lateral aperture sized for the passage of a standard golf ball therethrough from interior of the first cylinder is located adjacent to the end of the first cylinder and in proximity to the second cylinder.

Abstract: Three equally spaced contoured pads are installed around the center of the outer periphery of a conventional existing wheel rim. The pads are supported by brackets welded to the rim, and the contours of the pads form a circle when positioned correctly. The pads are flexibly moveable relative to the brackets to allow for instantaneous spin balancing during wheel rim rotation as occasioned by vehicle usage. In addition to spin balancing, the wheel safety rim functions to prevent a vehicle from riding on the wheel rim when an associated tire becomes deflated. Further provided is a specialized tool for facilitating the installation of the present device.

Abstract: The present invention relates to a wheelbarrow with an improved wheel assembly. The wheelbarrow includes brackets which are fixedly positioned with respect to the wheelbarrow adjacent to the front end thereof. An axle is formed of a rod with external threads, the axle having a center and opposed ends. Brackets are secured to the front legs adjacent to their lower extents with apertures for receiving the axle adjacent to its center. Cylindrical wheels are secured to the axle adjacent to the ends with tires thereon for rotation. Two internal bracket nuts are threadedly secured to the axle on opposite sides of the center in contact with the brackets at their internal faces. Two external wheel nuts are threadedly secured to the axle adjacent to their ends in contact with the wheels at their external faces. Intermediate nuts between the brackets and wheels are in contact with the external faces of the brackets and the internal faces of the wheels.

Abstract: Frictional resistance to motion of a boat is reduced by generating an unconfined layer of intermixed air bubbles and water adjacent at least a portion of the hull of the boat including at upcurving side surfaces of the hull. In the preferred form of the invention, an array of spaced apart airflow apertures in the hull extends outward and upward at each side of the keel at a plurality of locations along the hull. Air is forced through the apertures by a compressor or a forward facing air scoop or by a combination of both. In the preferred embodiment, barnacle inhibiting fluid may be released through the array of apertures when the boat is docked or at anchor.
