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: Golf balls having covers made of thermoplastic polyurethane compositions are provided. Multi-piece golf balls can be made. In one embodiment, the outer cover layer is formed from a composition comprising a thermoplastic polyurethane and polydimethylsiloxane compound. Functionalized polydimethylsiloxane compounds also can be used to treat thermoplastic polyurethane golf ball covers. The cover composition and surface coatings can further include catalysts, ultraviolet (UV)—light stabilizers, and other additives. The coating methods have many benefits and the finished balls with thermoplastic polyurethane covers have good physical properties.

Abstract: A co-forged iron type golf club is disclosed. More specifically, the present invention discloses an iron type golf club head from a pre-form billet that already contains two or more materials before the actual forging process resulting in a multi-material golf club head that doesn't require any post manufacturing operations such as machining, welding, swaging, gluing, and the like. The resultant golf club head may be capable of achieving center of gravity locations previously unachievable without utilizing this co-forging technique. The resultant golf club head may be used to create a set of golf club heads with center of gravity locations that are more advantageous throughout a set of golf clubs.

Abstract: A golf ball dimple half profile is disclosed herein that can be defined by a piecewise function. The sub-functions that define the piecewise function can include, for example, a catenary function and a Gabriel's horn function. A transition between the sub-functions defining the piecewise function is smooth. The sub-functions can have opposing concavities, and at least one of the sub-functions can have a non-constant radius of curvature. The golf ball dimple half profile is rotated about the dimple's centroid to create the full dimple profile.

The intermediate layer has a first portion that surrounds the core and a second portion that extends from the first opening to the second opening and thereby completely fills each through hole of the one or more through holes. The second composition is a thermoset or thermoplastic formulation comprising an elastomer. The cover surrounds the intermediate layer and the core.
