Abstract: The present invention is directed to a golf ball cover comprising a blend of copolymers wherein one or more of the copolymers is a low cost nonionic copolymer and one or more of the copolymers is an ionic copolymer. Surprisingly, a golf ball cover comprising the non-ionic/ionic copolymer blend exhibits no loss in C.O.R., and has equal resistance to cutting and cracking when compared to top grade golf ball covers made with one of the conventional 100% ionic copolymer blends. In particular, the present golf ball cover comprises from about 95 to about 80 pphr of one or more ionic copolymers, and from about 5 to about 20 pphr of one or more non-ionic copolymers, the latter being selected from the group consisting of a copolymer of ethylene and acrylic acid, a copolymer of ethylene and methacrylic acid, a copolymer of polypropylene and acrylic acid, a terpolymer of ethylene, acrylic acid and a lower alkyl acrylate, and a terpolymer of ethylene, methacrylic acid and a lower alkyl acrylate, and blends thereof.

Abstract: A composite golf club shaft and the method of constructing the shaft is disclosed. The hollow circular shaft includes a standard butt end having a constant outside diameter along a length of the shaft and a tip end having a constant outside diameter sustantially larger than the tip of a standard shaft, with the constant diameter of the tip end and butt end extending along predetermined lengths of the shaft. An intermediate section of the shaft tapers between the diameters of the butt and tip ends. The shaft is manufactured by wrapping a group of circumferential sections about a mandrel, each layer comprising either standard modulus carbon-graphite fibers or fiberglass fibers in a matrix, with the finished product being heat-cured to produce a golf club shaft.

Abstract: A golf shaft selectively reinforced with a composite outer shell substantially shorter in length than the golf shaft. A single shell is molded at a selected location over the shaft. The location of the shell controls the kick point of the golf shaft. The shell is comprised of a reinforced polymeric composite.

Abstract: A tennis racket comprising a frame formed of a pair of tubes attached together throughout the majority of the bow and then separated in the throat-beams for at least a portion of their extents; a yoke attached to the tubes adjacent to the ends of the throat-beams to form, in association with the portions of the tube, an essentially oval-shaped bow, the periphery of the bow having spaced holes therethrough; a single groove formed around the entire external periphery of the bow; a continuous grommet strip positioned within the groove and extending through the openings in the throat-beams and around the entire external periphery of the bow, the grommet strip being provided with spaced holes aligned with the holes of the bow; a bumper strip positioned under a portion of the grommet strip including the tip, the bumper strip being provided with spaced holes aligned with the holes of both the bow and the grommet strip, the holes of the bumper strip, grommet strip and bow being perpendicular to the tangent of the inn

Abstract: A golf ball is provided having a dimpled surface, the configuration of the dimples comprising a dimple-free equatorial line on the ball dividing the ball into two hemispheres, with each hemisphere having substantially identical dimple patterns. The dimple pattern of each hemisphere comprises a first plurality of dimples extending in at least two spaced clockwise arcs between the pole and the equator of each hemisphere, a second plurality of dimples extending in at least two spaced counterclockwise arcs between the pole and the equator of each hemisphere, and a third plurality of dimples substantially filling the surface area between the first and second plurality of dimples.

Abstract: A dimpled configuration for a golf ball wherein the dimples are arranged in a configuration so as to provide a dimple-free equatorial line, with each hemisphere of the ball having six identical dimpled substantially mating sections with a common dimple at each pole. Each section comprises six dimples lying substantially along a line parallel with but spaced from the equatorial line, twenty-nine dimples between the six dimples and the common polar dimple, with the outer dimples of each of said sections lying on a modified sinusoidal line. The ball preferably has 422 dimples.

Abstract: An improved steel golf shaft formed in a generally cylindrical configuraiton with a tip end and a butt end, the shaft having a central aperture extending axially the entire length thereof, three sets of steps continuously decreasing in diameter externally and internally from the butt end to the tip end, the steps of the central set being spaced from each other by a distance greater than the distance between the steps of the other sets. Also disclosed are the matched sets of clubs, woods and irons, employing such shafts as well as their methods of fabrication.

Abstract: A nursing unit is disclosed including a holder for a disposable liquid-retaining bag, the holder comprising an elongated tubular body open at both ends and having external threading at one end, an internally threaded retainer ring adapted to mate with the external threading on the tubular body, and a protective substantially rigid hood having an opening of a dimension to frictionally fit about said retainer or frictionally fit about the other open end of the tubular body.

Abstract: The present invention is directed to an improved golf ball core which exhibits an increased COR over golf ball cores made of conventional elastomer blends without sacrificing compressibility. In particular, the present invention is a golf ball core having an elastomer resin, and at least one metal salt of an unsaturated carboxylic acid, filler, fatty acid, and peroxide initiator, the improvement comprising the core further containing from about 0.1 to about 5.0 phr of a zinc salt of a compound of the formula: ##STR1## wherein n is n integer from 1-3, and m is an integer from 1-2.

Abstract: A golf ball is disclosed which has two poles and an equator and a modified icosahedral lattice wherein the lattice comprises five adjacent triangles on either side of the equator, with the vertices of each of the adjacent triangles being located at each of the poles and the legs of the triangles opposite said vertices being equidistantly spaced from the equator. Each triangle includes four dimples having a diameter D1 and two dimples having a diameter D2 located substantially centrally within the triangles. The remaining surface of the ball, including the remaining area within the triangles, contains dimples having a diameter D3. The diameter relationship is D1>D2>D3.

Abstract: A dimpled configuration for a golf ball wherein the dimples are arranged in a modified icosahedral lattice comprising a first set of five adjacent triangles on either side of the equator of the ball, with the vertices of each of the triangles being located at each pole of the ball and the sides opposite the polar vertices being spaced a distance from the equator of the ball. A second set of five triangles smaller than the first set of triangles equally spaced between the first set of triangles and the equator of the ball, each of the second set of triangles having a vertex common with adjacent ones of the first set of triangles, with the leg opposite the common vertex being parallel to but spaced from the equator.
