Abstract: A method of production of large Ingots of neutron attenuating composites using a vacuum-bellows system allows for large cross-sectional shapes to be extruded and rolled. A vacuum-bellows technology which allows the manufacturing of large diameter ingots. A variety of primary metal matrix materials can be used in this technology. High specific strength and stiffness can be achieved because the technology allows for final densities of 99% and higher. The vacuum-bellows technology allows metals and ceramics to blend and mesh together at compression pressures of 800 tons with elevated temperatures. The controlled compression movement allows for any oxide layer, on the metal, to be broken up and consolidated with the chosen ceramic particulate. By controlling the amount of boron-rich ceramics, by volume or weight, certain B-10 isotope areal densities can be accomplished. These B-10 isotopes attenuate neutrons in nuclear fuel. Other elements, which have high, cross-sectional Barn values can be used.

Abstract: A golf ball construction (2) is provided having a solid core composition of a rubber having between 3 to 25 percent by weight of an additive selected from the group of boron carbide, silicon carbide, and/or other advanced ceramic materials, the additives providing an improved core composition. The golf ball (2) further has an improved dimple arrangement in which each dimple (20) defines a dimple edge (24) adjacent a land area (22) of the golf ball, the dimple edge having a radius between 0.050 inches to 0.250 inches. The cover (6) of the ball additionally provides a surface marking opposite a balance point of the golf ball. The balance point of the golf ball being determined by floating the golf ball and allowing the ball to assume a resting configuration within the floating solution.

Abstract: An extrudable and weldable matrix alloy composite comprising: a) a base material metal of about 50 to 99.9% by weight, b) boron carbide or silicon carbide of about 0.1 to 50% by weight, c) less than about 3.0% by weight of at least one metal having an intermetallic phase temperature lower than the melting point of the base material metal, and d) a reinforcement agent of up to about 5% by weight.
