Abstract: The present invention is directed to improved multi-layer golf ball compositions having a core, an inner cover and an outer cover and the resulting regulation balls produced using these compositions. In this regard, a smaller and lighter core is produced and metal particles, or other heavy weight filler materials, are included in the inner cover compositions. This results in a molded golf ball exhibiting enhanced interior perimeter weighting. the heavy weight filler particles, such as powdered metals, are included in a relatively thick inner cover layer (or mantle) formed from an ionomer resin of a solid, three-piece multi-layered golf ball. The size and weight of the core can thereby be reduced in order to produce an overall golf ball which meets, or is less than, the 1.62 ounce maximum weight limitation specified by the United States Golf Association.

Abstract: The present invention is directed to molded golf ball core constructions and methods for improving the molded golf ball core construction. The molded golf ball comprises a molded spherical core having a soft skin integral therewith, and a cover molded over the core. The soft skin is formed by controlling exothermic molding temperatures. A slug is placed in a mold cavity which is then closed. A steam set point is set, and steam is applied for a 25-30 minute period such that a maximum mold temperature exceeds the steam set point. In the alternative, the core surface may be softened by first immersing a slug in water prior to subjecting the slug to conventional molding conditions.

Abstract: A golf ball comprising:a molded core; anda cover having a Shore D hardness of at least 65, wherein the cover is comprised of at least one high acid ionomer resin comprising a copolymer of greater than 16% by weight of an alpha, beta-unsaturated carboxylic, acid, and an alpha-olefin of which about 10% to about 90% of the carboxyl groups of the copolymer are neutralizer with a metal cation;wherein the low spin golf ball has a Riehle compression of 47 or greater and a spin rate of not greater than 6,933 revolutions per minute (r.p.m.) when struck with a No. 9 iron at a head speed of 105 feet per second and a launch angle of 26 to 34 degrees.
Abstract: A child carrier for use as a two-wheeled stroller and as a child-supporting backpack comprising a frame formed of an upper handle component in an inverted U-shaped configuration and a lower component formed of two downwardly extending legs and a cross-piece coupling the legs at their lower ends with a bracket at the lower ends of the handle and the upper ends of the legs for coupling therebetween. A fabric seat for a child has a rear face coupled to the bracket. An upwardly extending back and a pair of vertical straps form a front. A forwardly-extending U-shaped restraint is positioned in front of a child and secured at its inboard ends to the bracket supporting the upper edge of the seat. A pair of wheels are rotatably secured to the lower end of the legs.

Abstract: A golf club head set having the club head back side divided into four areas, including the perimeter weighted region A; the sweet spot area B located directly behind the ball striking area, two separated non-striking areas C, and the low central region D. The sweet spot area B is further divided into three distinct weight levels, and the low central region D is divided into four additional weight levels. By adding and dropping weight levels as well as by changing the thickness of the levels, the weight distribution of each club head is changed so as to control center of gravity and polar moment of inertia and provide gradated performance specific to each club head in the set.

Abstract: A composite, long wearing, slip-resistant non-metal golf cleat that alleviates damage to grass, e.g., the surface of a golf green, yet provides traction similar to conventional metal spikes is disclosed. The cleat provides a slightly higher, rounded, softer center core or tip which provides a measure of slip-resistance when walking on most hard, smooth dry surfaces and a firmer disk portion having multiple wing-shaped extensions to provide traction on turf surrounds the softer center.
Abstract: Disclosed herein is a golf ball having a scuff-resistant, soft cover formed from more than 90 wt. % of one or more acrylate ester-containing ionomeric resins. The acrylate ester-containing ionomeric resins preferably are terpolymers. The golf ball has good durability and a high spin rate. A method of making the golf ball also is disclosed.
