Abstract: The present invention is directed to golf balls having improved aesthetics and desirable aerodynamic properties due, at least in part, to the novel shape of the dimples on the surface thereof. In particular, the present invention is directed to a golf ball that includes at least a portion of its dimples having a shape obtained from the intersection of a toroid and a sphere. The resulting curve of intersection represents the dimple perimeter and the intersecting portion of the surface of the toroid represents the dimple surface shape.

Abstract: The present invention provides a golf ball wherein each hemisphere has a dimple pattern based on a pyramid having dissimilar sides. The resulting overall dimple pattern is not based on preexisting polyhedral, and is not attainable using conventional dimple packing methods.

Abstract: Golf ball comprising dimple(s) incorporating three or more linear channels having the same channel length L and same channel width CW; all linear channels extend radially outward from a centroid of the dimple toward a perimeter of the dimple without intersecting the dimple's centroid. Each linear channel may extend radially outward from a location on the dimple that is a distance Cd from the dimple's centroid, wherein Cd>0. Alternatively, at least one of the three or more linear channels has a different channel length L and/or a different channel width CW than at least one other linear channel. Dimple may have circular or non-circular plan shape; channels may not intersect each other; at least one linear channel may intersect the dimple's perimeter; and linear channels may be spaced by n separation angles θS, wherein n is number of linear channels, which may be equal, or at least two differ.

Abstract: The present invention provides a golf ball having an aerodynamic subsurface for packing dimples. More particularly, the invention relates to a golf ball having an exterior surface and at least a first subsurface containing at least two dimples located solely on the subsurface and lying below the exterior surface of the golf ball. A transition zone between the exterior surface and the subsurface is disclosed having an angle of transition and a top radius and a bottom radius.

Abstract: Golf balls including at least one modified dimple group are disclosed. The modified dimple group comprises one or more modified dimples forming an axially symmetric pattern about a Correction Area Centroid located on an axis of symmetry at a latitude greater than 0°, where 0° represents the hemispherical pole and 90° represents the equator. The modified dimples can be altered, for example, by changing dimple coverage, dimple diameter, dimple depth, dimple edge angle, dimple volume, dimple cross-sectional shape, and/or dimple plan shape. Optionally, the dimples have a catenary cross-sectional shape and the modified dimples are altered by changing the shape factor and/or chord depth. Such modifications preferably produce a golf ball that flies more consistently regardless of orientation when struck than a corresponding golf ball without such modifications.

Abstract: The present invention provides a method for arranging dimples on a golf ball surface in which the dimples are arranged in a pattern derived from at least one irregular domain generated from a regular or non-regular polyhedron. The method includes choosing control points of a polyhedron, generating an irregular domain based on those control points, packing the irregular domain with dimples, and tessellating the irregular domain to cover the surface of the golf ball. The control points include the center of a polyhedral face, a vertex of the polyhedron, a midpoint or other point on an edge of the polyhedron and others. The method ensures that the symmetry of the underlying polyhedron is preserved while minimizing or eliminating great circles due to parting lines.

Abstract: The present invention is a golf ball which comprises dimples having a cross section defined by the superposition of two or more continuous and differentiable functions, and particularly the superposition of a catenary function and a Witch of Agnesi function. Additionally, the dimples preferably have a circular boundary and maintain an axis coincident with the center of the circular boundary.

Abstract: Disclosed herein are polyurethane golf ball compositions. The compositions are prepared by adding a UV absorber to a polyol prior to reacting the polyol with an isocyanate to form a prepolymer, which is then reacted with a curing agent to form the polyurethane.
