Abstract: The present invention is directed to gelatinous elastomer compositions that are useful for topical application of biologically active agents. In certain embodiments, the invention is directed to a gelatinous elastomer composition comprising about 1.0% to 50.0% block copolymer, about 0% to 98% mineral and/or synthetic oil, and about 0.0% to 98% triglyceride oil, about 0-15.0% free fatty acids, about 0-30% of a tack modification agent, about 0-20.0% of a biologically active agent and, optionally a phytosterol, ceramide and/or bisabolol. The gelatinous elastomer compositions are useful for applying a biologically active agent to a mammal. In certain embodiments, the gelatinous elastomer composition is formed into a molded article.

Abstract: An improved cushioned liner (i.e., prosthetic liner) for covering a residual limb of an amputee is provided. According to one embodiment, the cushioned liner includes a sock-shaped fabric body member formed of at least two fabric pieces. One of the fabric pieces is a distal end piece that is attached to at least one other fabric piece along a circumferential edge of the distal end piece. The distal end piece is free of a transverse seam that extends across the distal end piece. The cushioned liner also includes a cushion layer disposed on at least one side of the sock-shaped fabric member. In another embodiment, a liner body having the above construction is provided and is adapted to receive cushioning material to form the cushioned liner.

Abstract: The present invention relates to alloys containing about 50-90% palladium, 0-37% gold, 0-3% platinum, 0-35% silver, 0.5-8% gallium, 0-8% tin, and up to 0.2% of a grain refiner selected from the group consisting of iridium, rhenium and ruthenium, or mixtures thereof. In order to withstand the forces of mastication over long spans or cantilever sections, the alloys are more rigid than conventional palladium based alloys. The alloys may be utilized for conventional crown and bridgework or may be fabricated into a number of different prostheses for use on dental implants. These applications include, for example, metal base plates for dentures, metal retaining bars for removable or fixed removable dentures, full metal coverage crowns and bridges, and metal substructures to be veneered with resin or porcelain materials.

Abstract: Dental restorations are made of a high palladium alloy which consists essentially of, on a weight basis, 70-82 percent palladium; 5-8 percent gold; 6.5-8 weight percent silver; 5-9 percent gallium; from 4 to 8 weight percent of a surface oxide producing modifier selected from the group consisting of indium, tin and mixtures thereof, from 0.01 up to 2 percent, ordinarily less than about 0.5 percent, of an oxygen scavenging component which is a member selected from the group consisting of germanium, lithium and mixtures thereof; and up to 2 percent of a grain refiner selected from the group consisting of ruthenium, rhenium and iridium. Alloy can be melted without the need of shielding the alloy from the atmosphere.

Abstract: Dental restorations are made of a palladium alloy which consists essentially of, on a weight basis, 50-85 percent palladium; 5-40 percent of at least one metal selected from the group consisting of copper and cobalt; 1-15 percent gallium; up to 5 percent of a modifier selected from the group consisting of nickel, gold, indium, ruthenium, tin and mixtures thereof; from 0.005 up to 1 percent, ordinarily less than about 0.2 percent, of an oxygen scavenging component which is a member selected from the group consisting of germanium, lithium, and mixtures thereof; and up to 0.5 percent of a grain refiner selected from the group consisting of rhenium and iridium. The alloy is free of boron.

Abstract: A yellow dental alloy containing a colored intermetallic compound of palladium and indium as 15-85% by weight of the alloy and at least 10% by weight of silver and as desired gold 0-30%, copper 0-45% and silver 10-50%. This alloy exhibits a pale yellow gold color which it derives from the interaction of two white colored metals--palladium and indium. Various alloying additions are specified to improve castability, ductility, strength, hardness, tarnish and corrosion resistance.

Abstract: A dental restoration includes a casting of a palladium/silver alloy which comprises 45-60 percent palladium, 25-45 percent silver, 3-15 percent tin and/or indium, 0.3-9.0 percent zinc, 0.1-1.0 percent silicon, up to 0.25 percent rhenium and/or iridium, and up to 5 percent in total of one or more of copper, magnesium, gallium and ruthenium. The dental restorations obtained by firing porcelain against castings of this alloy exhibit freedom from discoloration, and excellent bond strength is are obtained between the porcelain coating and the underlying alloy casting.

Abstract: A tarnish-resistant gold color alloy comprises 30-50 percent by weight gold; 20-50 percent copper; 5-15 percent silver; 2-20 percent zinc; 1.5-15 percent palladium; up to 4.0 percent by weight platinum; and up to 1.0 percent by weight rhenium. The atomic ratio of copper to silver, copper to zinc and copper to palladium are respectively, 6-8:1; 2-12:1; and 5-30:1 and the weight ratios are respectively, 3.5-4.7:1; 3.0-18:1; and 1.95-11.66:1. Dental restorations comprising castings of the alloy have color values on the Hunter scale of L=80-90; a=2.5-3.5; and b=14-18. The dental restorations exhibit tarnish-resistant values of DE.sub.1 less than 13 and DE.sub.10 less than 20.
