Abstract: A golf ball includes a spherical outer surface and a plurality of dimples formed thereon. The dimples have an inner land surface with at least one spiral depression either disposed or superimposed on the inner land surface to energize or agitate the airflow over the dimpled surfaces to increase the aerodynamic performance of the golf ball. The spiral depression may turn clockwise or counterclockwise and can be either spaced apart, touching or overlapping each other. While the dimples may be circular, polygonal, triangular or elliptical, dimples having a cross section greater than 0.18 inch are preferred. The dimples may also comprise spiral depressions directly on the spherical surface of the ball.

Abstract: The present invention is directed to a three-component releasable mounted cleat assembly for interlocking into a receptacle of a golf shoe. A locking component is biasly inserted into an open receptacle in the shoe and has a geometric construction of downwardly extending tongues causes a requirement for a greater torque remove the cleat than was necessary to install it. An outer component which is coupled to the locking component provides a plurality of rigid posts extending outward for firmly gripping turf. The posts have an exterior wall surface extending vertically from a base and are confined within the outer perimeter of the base. An inner component is secured within the outer component and has a plurality of resilient legs extending outward in a radial direction and originating from a central area of the component.

Abstract: A replaceable cavity insert for use in a multi-cavity compression mold, wherein each cavity insert is friction fitted into a respective mold recess. Each insert has a substantially semi-spherical insert surface and defined in the surface is an inverted dimple pattern of a golf ball. Each cavity insert has an O-ring recessed in the upper perimeter to limit the flow of heating and cooling fluids beyond the perimeter. The cavity insert and the O-ring are retained in the recess of the frame by a pair of removable cavity retainer screws and washers, which are countersunk into the frame and have an edge of the washer disposed in a cut-out section of the insert. Each cavity insert may be separately and individually removed from the frame by just loosening the retaining screws without the need to remove the entire frame from the press or disconnecting the utility lines leading to the frame.
