Abstract: The present invention is directed towards a multi-layered core golf ball that comprises a thermoplastic inner casing layer molded between two polybutadiene core layers to create a faster golf ball with less spin, by designing a ball that has more of the stored energy of the core released at impact. One inner casing layer and/or an outer core layer is comprised of a partially or fully neutralized ionomer.

Abstract: A golf ball comprising a cover and a core, and optionally at least one intermediate layer interposed between the cover and the core, wherein the cover or the intermediate layer or both are formed from a blend comprising a thermoplastic silicone-urethane copolymer. The silicone content of the silicone-urethane copolymer is between 1 and 20 percent by weight.
Abstract: A golf club head having selectively oriented zones of relatively high flexural stiffness is disclosed. The hitting face is configured and dimensioned so that it includes an inner zone and a concentric intermediate zone. The inner zone has relatively high flexural stiffness and the intermediate zone has relatively lower flexural stiffness. The inner zone may have an elliptical shape or a substantially parallelogram shape. Preferably, the inner zone has a shape that comprises a major axis and a minor axis and the major axis aligns substantially in the direction of high heel to low toe. This arrangement of inner and intermediate zones creates a gradient of flexural stiffness in the direction of high toe to low heel and produces a desirable manipulation COR in that direction. This area of high coefficient of restitution advantageously coincides with the ball impact pattern that golfers typically make on the hitting face.
Abstract: The present invention is directed towards a method of manufacturing a multi-layered golf ball, with at least an inner cover having multiple layers formed by a sandwich injection molding process. The multi-layered inner cover comprises an inner layer and an outer layer of a first material and an intermediate layer therebetween of a second material. The materials having different properties.

Abstract: A fishing lure for use as a top water lure having a construction of negative buoyancy. The lure has an elongated weighted body resembling a squid with angled channels defined in the top and bottom surfaces of the body. Upon the lure being retrieved by an angler, water gushes through one of the channels and splashes over and about the leading end of the lure, causing the lure to “swim” over the water surface with the trailing end submersed in the water. This presents the appearance of a fleeting baitfish. By careful selection of colors and reflective strips the lure will have an appearance that is very visually stimulating to game fish.
Abstract: The present invention is directed towards a multi-layered core golf ball that comprises a center, a cover and at least two core layers formed around the center to create an inner ball, wherein the outermost core layer is relatively stiff and hard relative to the center. At least the center or/and one core layer is comprised of an ionomer resin having a fully neutralized acid moiety.

Abstract: A golf club iron having a thin front face which is supported by a biasly bent L-shaped insert that is disposed into a rear cavity of the iron to both support the front face and to create a “spring like” effect. The coefficient of restitution of the club head is greater than 0.8. The insert has a lower specific gravity and a higher Young's Modulus than the front face.
