20120088601 | GOLF BALL WITH IMPROVED FLIGHT PERFORMANCE - A golf ball with aerodynamic coefficient magnitude and aerodynamic force angle, resulting in improved flight performance, such as increased carry and flight consistency regardless of ball orientation. In particular, the present invention is directed to a golf ball having increased flight distance as defined by a set of aerodynamic requirements, at particular spin ratios and Reynolds Numbers. The invention is also directed toward golf balls having high spin decay rates during the first second of flight that yields improved flight performance and longer ball flight. | 04-12-2012 |
20130040759 | EXTENDED SPIN INERTIA GOLF BALL - This self correcting smart ball, typically a golf ball, overcomes certain sudden and unanticipated conditions or disturbance during play such as wind gust, drags, bump, debris, divides etc. during flight or roll on the surface (green), as faced by players, essentially taking the expertise out of the game and making the game more on a chance basis. This is achieved by separating the inner core, which absorbs the energy, momentum, direction and spins during the impact of ball and the club, and outer shell by a layer of fluid of certain viscosity, which act as an element to transfer energy, to and from the outer shell to the inner core, as needed, in order to perform what it is supposed to perform. This separation of the shell and core essentially immunes the ball from unanticipated disturbances thereby taking the uncertainty and chance out of the game. | 02-14-2013 |

The aqueous solution can be thixotropic, or rheopectic, or dilatant, or pseudoplastic in nature and the center formulated to simulate the specific gravity of the solution. | 04-11-2013 |
20130281232 | MULTILAYER GOLF BALL - A method of making a ball, comprising: forming an inner core having a diameter of about 0.5 inches or lower; forming a plurality of outer core parts from an elastomeric material, each outer core part having an inner surface, an outer surface and at least one non planar mating surface, wherein the inner surface is concentrically disposed within the outer surface and comprises a cavity for receiving the inner core, and wherein the at least one nonplanar mating surface extends radially between the inner surface and the outer surface and comprises a plurality of mating ridges which extend from the inner surface to the outer surface; forming an outer core by mating the outer core parts about the inner core and joining the nonplanar mating surfaces by meshing the mating ridges to form a multi-layer core having a nonplanar parting line which extends about the outer surface circumferentially and intersects with the mating ridges at the outer surface; and molding a cover about the inner core, wherein the elastomeric material has a cohesive strength and the parting line has a mated strength equal to or greater than the cohesive strength. | 10-24-2013 |
20140011608 | MULTILAYER GOLF BALL - A method of making a ball, comprising: forming an inner core having a diameter of about 0.5 inches or lower; forming a plurality of outer core parts from an elastomeric material, each outer core part having an inner surface, an outer surface and at least one non planar mating surface, wherein the inner surface is concentrically disposed within the outer surface and comprises a cavity for receiving the inner core, and wherein the at least one nonplanar mating surface extends radially between the inner surface and the outer surface and comprises a plurality of mating ridges which extend from the inner surface to the outer surface; forming an outer core by mating the outer core parts about the inner core and joining the nonplanar mating surfaces by meshing the mating ridges to form a multi-layer core having a nonplanar parting line which extends about the outer surface circumferentially and intersects with the mating ridges at the outer surface; and molding a cover about the inner core, wherein the elastomeric material has a cohesive strength and the parting line has a mated strength equal to or greater than the cohesive strength. | 01-09-2014 |
20140051530 | GOLF BALL WITH RADIALLY COMPRESSED INTERMEDIATE LAYER - A method of forming a golf ball includes molding a golf ball core through at least one of injection molding and compression molding, and subsequently volumetrically contracting the core. Once the core is contracted, an intermediate layer is formed about the core, and the core is subsequently allowed to expand to an intermediate state such that the core applies a contact pressure against an inner surface of the intermediate layer. | 02-20-2014 |
20160082322 | Short-Flight Ball, and Related Methods - A ball comprises a core and a surface that covers the core. The surface includes at least one groove having a depth, a length and a width, wherein the length of the groove is at least three times the width, and wherein the length of the groove extends at most fifty degrees across the surface of the ball. When the ball travels through the air, the groove trips and obstructs the flow of air across the ball's surface, increasing the air's drag on the ball. This increase in drag causes the ball to not travel as far as a regular ball when well hit, and opposes any spin imparted to the ball when hit. In addition, the surface of the ball generates a sound that mimics a whistle while air flows across the surface to warn others of the ball's flight. | 03-24-2016 |
20160136485 | Multi-Layer Golf Ball with Bladder Core - The present disclosure is directed to a golf ball and a method for manufacturing a golf ball including a bladder core. In at least one embodiment, the bladder core includes an ethyl vinyl alcohol copolymer layer combined with multiple layers of thermoplastic polyurethane or other material to prevent leakage. In addition, it is contemplated that the bladder core may include a one-way valve for adjusting the pressure of a fluid within the bladder core to produce different performance characteristics. | 05-19-2016 |
