Abstract: A nets configuration for the dimples on the surface of a golf ball is characterized by at least a portion of the bottom surface of the dimple extending below a radius of curvature which defines the concavity of the dimple. Thus, the dimples have a non-symmetric depth profile. The dimples are preferably circular and the non-symmetrical portions are maintained within one half of the dimple.

Abstract: The present invention is directed to a solid, non-wound, golf ball comprising two or more core components, and a cover component. The core components comprise i) a small, inner, high density, spherical center component comprising a blend of powdered metal and a first matrix material comprising polybutadiene and polyisoprene; and, ii) an outer core layer disposed about the spherical center component, formed from a second matrix material selected from the group consisting of a thermoset material, a thermoplastic material, or combinations thereof. The golf ball may further comprise a second or additional outer core layer(s) that surround the first outer core layer. Preferably, the inner, high density, center component is produced without the use of a crosslinking agent or coagent, which is the reaction product of an unsaturated carboxylic acid or acids and an oxide or carbonate of a metal such as zinc. The cover may be single or multi-layered.

Abstract: A unique golf ball and related methods of manufacturing are disclosed in which the golf ball comprises one or more mantle layers comprising one or more metals, ceramic, or composite materials. The golf ball may also comprise an optional polymeric spherical substrate inwardly disposed relative to the one or more mantle layers. The golf balls according to the present invention exhibit improved spin, feel, and acoustic properties. Furthermore, the one or more interior mantle layers prevent, or at least significantly minimize, coefficient of restitution loss from the golf ball, while also significantly increasing the movement of inertia of the golf ball.
