Abstract: The invention relates to a catalyst element for a recombinator for eliminating hydrogen from accident atmospheres, in which the technical problem of continuously efficiently converting both small and large amounts of hydrogen with the atmospheric air-oxygen present in the safety containers within a broad concentration range, and routing away the reaction heat arising in the process to such an extent that the respective ignition temperature is not reached in the present mixture is resolved by having the catalyst element exhibit a flat basic body (2), which is arranged within the area of flow through the recombinator, wherein the surface of the basic body (2) over which the accident atmosphere flows has a varying coverage density with catalyst material (3).

Abstract: Disclosed is a two-piece solid golf ball satisfying the following conditions (1) to (4): (1) a cover predominantly contains a polyurethane material; (2) the cover has a JIS C hardness of 72 to 89, and a thickness of 0.70 to 1.95 mm; (3) a core is formed from a rubber material containing an organic sulfur compound; and (4) a center portion of the core has a JIS C hardness of 58 to 68, a surface portion of the core has a JIS C hardness of 71 to 87, and a value obtained through subtraction of the JIS C hardness of the center portion of the core from the JIS C hardness of the surface portion of the core is 8 to 21. The golf ball exhibits excellent feeling on impact, controllability, cut resistance, scratch resistance, and durability against cracking caused by repeated hitting, and has improved flight performance; i.e., an improved carrying distance particularly upon being hit upwind.

Abstract: The device according to the invention uses the chemical energy stored in an explosive charge to increase the speed of a golf ball at impact with a golf club head. The device serves also as a training tool for the golf swing precision since the charge is set off only when the golfer hits the “sweet spot” on the club's head. Otherwise, the golfer experiences a regular swing. A golf club head has a cavity accepting a .22 caliber blank. The blank charge is set off upon impact with the golf ball. The high pressure of the gas thus released causes the golf club to propel the golf ball farther and faster than the regular golf club impact. Furthermore, since the discharge creates a loud “bang”, this sound confirms that the hit was perfect.

Abstract: In a two-piece solid golf ball comprising a solid core and a cover, the JIS-C hardness at the core surface minus the JIS-C hardness at the core center is 20-30 units, the cover has a gage of 1.3-2 mm and a Shore D hardness of 40-55, and the JIS-C hardness at the cover surface is not greater than the JIS-C hardness at the core surface. Dimples are formed on the cover surface to satisfy a total number of 360-492 and a percent dimple volume VR of 0.74-0.84%. The golf ball is susceptible to spin and easy to control upon approach shots and short iron shots, travels a long distance upon driver shots, gives a pleasant feel on any shot with driver, iron and putter clubs, and offers improved playability satisfying low-handicap players.

Abstract: A golf club (40) having a club head (42) with a face component (60) and an aft body (61) is disclosed herein. The face component (60) has a striking plate portion (72) and a return portion (74). The aft-body (61) is composed of a crown portion (62), a sole portion (64) and optionally a ribbon section (90). The face component (60) is composed of a metal material, and the aft-body (61) is composed of a non-metal material such as a composite material or a thermoplastic material. The striking plate portion (72) preferably has an aspect ratio less than 1.7. The striking plate portion (72) preferably has concentric regions of thickness with the thickness portion in the center (102). The club head (42) has a volume in the range of 290 cubic centimeters to 600 cubic centimeters, a weight in the range of 165 grams to 300 grams, and a striking plate portion (72) surface area in the range of 4.00 square inches to 7.50 square inches. The golf club head (42) has a coefficient of restitution greater than 0.

Abstract: A golf club (40) having a club head (42) with a frame member (60) and a body (61) is disclosed herein. The front member (60) has a front portion (72) and a return portion (74). The body (61) has a crown portion (62), a sole portion (64), a front wall (87) and optionally a ribbon section (90). A transition from the front wall to the crown portion (62) has a radius of curvature of at least 0.250 inch. The softer radius of the transition allows for a more durable and better performing club head. The frame member (60) may also be weighted to move the center of gravity of the club head forward toward the front wall (87).

Abstract: A golf ball includes a core, and a cover made from a cover material containing an ionomer resin and also barium sulfate and titanium dioxide added in a total amount ranging from 10 to 25 parts by mass on the basis of 100 parts by mass of the ionomer resin. A flexural amount of the core, measured by applying a load of 980 N thereto, is in a range of 4.0 to 5.5 mm. A ratio of a melt-flow rate to a specific gravity (melt-flow rate/specific gravity) of the cover material is in a range of 1.6 or more. A Shore D hardness of the cover is in a range of 55 to 65.

Abstract: The invention includes a golf ball having a core, a hoop-stress layer of high tensile elastic modulus material wrapped or wound about the core, at least one outermost layer of a thermoset material having a thickness of greater than about 0.065 inches. A binding material can be used in conjunction with the hoop-stress layer to facilitate positioning of the hoop-stress layer around the core for easier manufacturing.

Abstract: A new, novel and useful Oriented Thermoplastic Elastomer Thread Wound Golf Ball providing improved combinations of good spin for ball control on iron or wedge shots while providing for higher hardness and long travel with driver shots. The Oriented Thermoplastic Elastomer Thread Wound Golf Ball's performance is acheived by the incorporation of oriented thermoplastic elastomer threads in the golf ball design.

Abstract: A golf club head for hitting a golf ball farther than existing golf club heads and having a cast sole and a crown joined seamlessly as one piece with an opening for a face plate to be fitted into the body, and a face plate fabricated from sheet metal, precision cut by laser and precision formed in a die under extremely high pressure that includes a lower portion and an upper portion. The sole and crown part of the body are cast thinner than most other club heads to promote deformation when striking a golf ball. A parabolic shaped rise in both the crown and sole provide increased lateral strength while aiding in reducing the deformation of the ball at impact. The lower portion of the face has two end portions, and a center portion with the end portions having a first thickness. The center portion and the upper portion of the face have a second thickness that is thicker than the first thickness. In addition, the face plate is welded or bonded into a front opening of the cast body.

Abstract: A golf club head is provided with a residual compressive stress layer on the inside surface of the club face using a peening treatment. The peening treatment also may remove material from the club head, such as unwanted alpha case on a titanium club head. The body of the club head further may be subjected to a peen treatment.

Abstract: In a multi-piece solid golf ball comprising a solid core, an inner cover layer and an outer cover layer, the solid core is molded from a rubber composition comprising a base rubber composed of (a) 20-100 wt % of a polybutadiene having a high cis-1,4 content, a minimal 1,2 vinyl content and a viscosity &eegr; of up to 600 mPa·s at 25° C. as a 5 wt % toluene solution, and satisfying a certain relationship between Mooney viscosity and polydispersity index in combination with (b) 0-80 wt % of another diene rubber, (c) an unsaturated carboxylic acid, (d) an organosulfur compound, (e) an inorganic filler, and (f) an organic peroxide; and the outer cover layer has a higher Shore D hardness than the inner cover layer. This combination of features gives the ball a good, soft feel upon impact and excellent flight performance.

Abstract: A sole of a head is inclined upwardly toward a side of a hosel section. A proximal section of the hosel section, which is continuous to a top, is set to be low. Accordingly, the weight of the head on the side of the hosel section is reduced, while the weight is distributed to circumferential portions of the head. Thus, the moment of inertia is set to be increased, and the sweet area is substantially enlarged.
