Abstract:

A golf ball construction () 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 () further has an improved dimple arrangement in which each dimple () defines a dimple edge () adjacent a land area () of the golf ball, the dimple edge having a radius between 0. 050 inches to 0. 250 inches. The cover () 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:

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. This method uses a vacuum-bellows technology which allows the manufacturing of large 8–16 inch diameter ingots (50–450 lbs. each). 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. One application is to blend boron-rich ceramics and high purity (99. 5–99. 99%) aluminum particulates together and produce a large ingot using this vacuum-bellows technology.

Abstract:

Unlike conventional dental ceramic powder made by grinding, dental ceramic nanocrystals are formed by vaporization into individual particles. Tetragonal zirconia particles thus formed are not broken into pieces, and so do not transform to weaker monoclinic zirconia and weaker sintered products. The particles created by this approach can be much smaller, and dental prostheses sintered from this powder can be stronger and more realistic. For instance, the smaller size of sintered tetragonal zirconia crystals increases optical translucence by reducing scattering from birefringence, and the small average particle size and tight distribution of sizes and shapes can essentially eliminate pores in a sintered product. Cylindrical and spherical particles can be manufactured by this approach, whereas prior art dental ceramic particles were generally neither. In addition to tetragonal zirconia, various dental ceramic particles and powders can be made by this approach, which can be used to form various sintered dental prostheses.

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:

Dental restorations such as crowns, are made from lithium silicate glass ceramic that is heated and pressed onto a metal substrate, the latter being shaped to an impression or scan of the area of the mouth to receive the restoration. The metal substrate is made from an alloy selected to exhibit a coefficient of thermal expansion which is slightly greater than the CTE of the lithium silicate. In a preferred embodiment, the CTE of the lithium silicate glass ceramic is in the range of 11.5 to 12.5 and the alloy is selected to have a CTE of 12 to 13.5. A palladium tin alloy provides that CTE in the preferred embodiment.

Abstract:

A process to make/seat a permanent crown in only one patient visit, without the need for a temporary crown, after a digital scan or other impression has been taken prior during a dental cleaning appointment or status check up. The dental information is filed and can be used whenever the patient needs a dental restoration to be made. The impression information will have previously been forwarded to a dental laboratory where a shell-crown can be made that is a perfect match to the outer contour of the existing tooth. Needed improvements/corrections can be made with the use of digital software. Also the margins can be determined and corrected, even in the inter-proximal spaces. Now the laboratory is able to manufacture and provide a finished shell-crown in time for the following doctor appointment of this patient.

Abstract:

Rapid sintering techniques for densifying zirconium dioxide based ceramic materials employing electromagnetic induction heating or inductive coupled plasma, reducing processing time from hours to minutes. In one embodiment a water-cooled coil is connected to a radio frequency power supply. The coil surrounds a susceptor body which in turn surrounds the ceramic to be sintered. The susceptor heats up in response to a magnetic field emanating from the coil as the coil receives electric power. The heat in turn is radiated from the susceptor and heats the ceramic. In another embodiment, the coil is connected to a radio frequency power supply of sufficiently high frequency and power to establish a plasma in the gas which surrounds the ceramic. The plasma then heats the ceramic. The method is especially useful for sintering ceramic dental appliances, in minutes which can lead to in situ fabrication of such appliances while a dental patient waits.
