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: 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.

Abstract: An aerodynamically symmetrical golf ball is provided including a patterned outer surface having 492 dimples arranged in twenty triangles based upon an inscribed modified icosahedron lattice on the surface of the ball. As a result of the modification of the lattice, a predetermined spacing exists between two in-line rows of dimples on opposite sides of an equatorial line about said ball, the spacing being created by the modification of th icosahedron on the surface of the ball.

Abstract: An improved golf ball comprising a core and a cover therefor, said cover comprises singularly or blends of a zinc neutralized ethylene-acrylic acid copolymer and a sodium neutralized ethylene-acrylic acid copolymer, or a blend of two or more zinc-neutralized ethylene-acrylic acid copolymers and a sodium-neutralized ethylene acrylic acid copolymer.

Abstract: A dimpled configuration for a golf ball wherein, in the first embodiment, the dimples are arranged in a geometrical lattice configuration so as to form a perfect icosahedral pattern which inlcudes twenty indentical triangles with a predetermined number of dimples lying along the lines forming the lattice. These dimples are a first diameter, while the dimples within the lattices are of a second diameter greater than the first diameter. In the second embodiment, the five adjacent triangles having common polar vertices are retained on either side of the equatorial line of the ball. Five smaller triangles on either side of the equator include vertices common with each adjacent set of the five triangles, with the legs opposite such vertices being substantially parallel with but terminating short of the equatorial line of the ball. The legs parallel with the equator extend about the ball so as to form five trapezoids which have common sides with the alternate with the five small triangles.

Abstract: The disclosure relates to golf balls and more particularly, to golf ball cover compositions. The disclosure is concerned primarily with composition and method for the enhancement of the color of a golf ball cover by the use of an optical brightener in conjunction with a pigmented golf ball cover composition. This invention is concerned with the enhancement of the color of white golf ball covers. When used in conjunction with a white pigmentation system, the optical brighteners in question enhance the color in the blue spectrum range in order to give the cover a whiter appearance.

Abstract: The disclosure embraces a golf ball and method of making same wherein the golf ball has a solid (not thread-wound) resilient center or core, and a multilayer cover construction which involves a first layer or ply of molded hard, high flexural modulus resinous material on the core, and a second or cover layer of soft, low flexural modulus resinous material molded over the first layer to form a finished golf ball. The first layer is of a thickness in a range of 0.020 inches and 0.070 inches and may be of resinous material such as Type 1605 Surlyn marketed by E. I. du Pont de Nemours and Company, and the second or cover layer is of a thickness in a range of 0.020 inches and 0.100 inches and may be of resinous material such as Type 1855 Surlyn marketed by E. I. du Pont de Nemours and Company. Foamable materials for producing a cellular first layer or cellular cover layer are polymeric materials such as ionomer resins.
