摘要: A multiple layer golf ball having a high compression core and a soft boundary layer is disclosed herein. The multiple layer golf ball may also have a hard cover. The soft boundary layer allows the multiple layer golf ball to mimic the properties of a lower compression core while providing good distance. The multiple layer golf ball has a low driver spin and a high pitching wedge spin. The boundary layer is composed of a polyurethane formed from a PPDI-based prepolymer while the core is composed of a polybutadiene. The cover may be composed of an ionomer blend.

摘要: An assembly which is adapted for mounting inside a mixing drum (18) and a mobile system for mixing and dispensing concrete includes a spiral fin assembly (36) for mixing and guiding a substance when the mixing drum (18) is rotated. The fin assembly (36) is constructed of a lightweight polymeric material which is resistant to abrasion, is many times lighter than steel, and tends to wear smooth rather than rough, which increases the cleanability of the fin structure over its entire design life. Novel structure for securing the fin assembly (36) to an outer wall (38) of the mixing drum (18), novel structure of fin assembly (36), and novel structure for connection of adjacent fin sections are also disclosed.

摘要: A method for manufacturing a golf club head with an insert having a face plate is disclosed herein. The insert is disposed in a recess of the club head in which the recess has a depth that is greater than the thickness of the insert. The insert preferably has a plurality of tabs on its perimeter to engage the recess walls to allow the insert to essentially float within the recess. An adhesive is preferably disposed between the rear wall of the recess and an interior surface of the insert. Further, an adhesive is applied between the plurality of tabs, and preferably over the exterior surface of each of the plurality of tabs.

摘要: A method of manufacturing golf balls is disclosed that prevents the cover from cracking due to thermal expansion of the core during the cover formation process. The method includes the forming a core. One or more optional boundary layers can be applied to the surface of the core. The core and any boundary layers are pre-heated such that the core and any boundary layer undergo volumetric thermal expansion. After the pre-heating, the cover of the ball is formed over the core and any boundary layer. The method of the present invention also decreases cover molding cycle times for golf balls.
