Abstract: A method for treating as as-grown chemical vapor deposited (CVD) starting diamond film having stresses and containing voids, comprises the step of subjecting the diamond film to a temperature of above about 1000.degree. C. and a hydrostatic pressure of above about 3 kilobars.

Abstract: In its broadest aspects, the present invention is directed to a method for improving the abrasion resistance of the annular interior surface of an annulus. Such method comprises the steps of (a) placing said annulus heated to an elevated CVD diamond-forming temperature in a vacuum chamber held under reduced pressure; (b) providing a hydrocarbon/hydrogen gaseous mixture within said chamber; (c) at least partially decomposing said gaseous mixture in said chamber; and (d) directing said at least partially decomposed gaseous mixture into said heated annular interior for diamond deposition/growth to occur on said annular interior surface. As noted above, spray nozzles, valves, injectors, wire drawing dies, and like annular products are ideally suited for use in accordance with the precepts of the present invention.

Abstract: A method produces a columnar, quasi-oriented diamond that exhibits the enhanced optical, thermal and mechanical properties of gem diamonds. This method allows diamond growth rates that are faster than those possible with high pressure diamond growth from a single diamond seed. The columnar, quasi-oriented diamond contains lower grain boundary density than chemically vapor deposited diamond.

Abstract: Carbon fluoride solid compositions having a low fluorine-to-carbon ratio are produced by chemical vapor deposition processes. These carbon fluoride compositions have improved wettability characteristics over polytetrafluoroethylene. These compositions can be used as films, coatings on substrates, powders, and stand-alone articles. These carbon fluoride compositions are produced by energizing vapors comprised of compounds containing fluorine and carbon to cause them to degrade into fragments which are then condensed onto a substrate to form the carbon fluoride solids. These vapors can be energized by a variety of techniques, including hot filament techniques. The carbon fluoride solids find utility as films in aircraft de-icing, cookware, appliances, surgical tooling, chemical processing, gaskets, seals, diaphragms, packings, valve seats, windings, mold release components, extruder coatings, medical prosthetics, and other similar non-wetting applications.

Abstract: Superconducting joints between superconducting tape ends are produced by a series of operations which includes stripping non-superconductive material from the tape ends, joining them with a conductive coating and depositing a superconductive alloy layer thereon, typically of triniobium tin, by a chemical vapor deposition reaction of hydrogen with the corresponding metal halides. Certain of the steps are performed in an inert atmosphere free from moisture, elemental hydrogen and elemental oxygen, typically a helium atmosphere.

Abstract: A carbon chalcogenide macromolecular composition prepared from carbon dichalcogenide and to a process for the preparation thereof. A carbon dichalcogenide, for example, carbon disulfide, in entrained in an inert gas, and the mixture formed therefrom is passed over a hot tungsten filament wherein carbon disulfide is degraded into fragments. The fragments are then deposited onto a surface of a non-reactive substrate. The deposited fragments recombine to form the macromolecular composition. A significant characteristic of the composition is its threshold voltage above which its electrical resistance drops precipitously. This characteristic also exhibits a unique temperature dependence. Dopants may be added to the composition to reduce the electrical resistance.

Abstract: The effluent stream from a process for producing phenolic compounds is reacted with an aldehyde in the presence of a base to form a water soluble resol which is useful in enhanced oil recovery.

Abstract: Catalyst for the production of methane from carbon and/or coal by means of catalytic gasification. The catalyst compostion containing at least two alkali metal salts. A particulate carbonaceous substrate or carrier is used.

Abstract: Coal particles, typically having a particle diameter below approximately one micron, are produced by mechanical fracturing, the addition of a swelling agent, the further mechanical fracturing and removal of the swelling agent. In particular, gaseous anhydrous ammonia is employed as the entrainment fluid and swelling agent in a fluid energy mill for coal comminution.
