Abstract: A multiple density golf club head including a heel formed of a dense metallic material, a toe formed of a dense metallic material and a center segment formed of a non-metallic material is provided. The non-metallic material of the center segment has a density substantially less than the metallic material comprising the heel or the toe. The materials in the heel, toe and center segment extend for the entire depth of the club head. The positioning of the higher density regions at the heel and toe of the golf club provides for desirable heel-toe weighting characteristics. Also disclosed is a method for manufacturing a golf club head in accordance with the present invention. The method incorporates various manufacturing techniques into a cost effective process for manufacturing the club head of the present invention.

Abstract: For use with a wheel having a hub adapted to be secured to a mounting structure by at least one stud extending through a hole in the hub and by a nut fastened to the stud, the hub including a first surface facing the mounting structure and a second surface opposed to the first surface, a wheel hub cover appartus for protecting a portion of the hub adjacent the hole against exposure to fluids includes structure for sealing each surface of the hub adjacent the hole. On the first surface of the hub, a gasket is provided which is adapted to be interposed between the wheel hub and the mounting structure during attachment of the wheel to the mounting structure so that the portion of the hub adjacent the hole is protected from exposure to fluids that are present in the vicinity of the first surface of the hub.
