Abstract: Solid superacid catalyst, for example sulfated zirconia, is used in the oxidative dehydrogenation of saturated or partially saturated hydrocarbons, for example the conversion of isobutane to isobutylene in the presence of an oxygen-containing oxidizing agent at reaction conditions typically including temperatures from 500 to 1,000 degrees Fahrenheit, superatmospheric pressures, and oxygen/alkane molar ratios from 0.2 to 20. Performance of a metal-oxide or metal-hydroxide oxidative dehydrogenation catalyst may be enhanced by pretreating a solid superacid or other catalyst containing metal oxides or hydroxides at a carbonizing temperature with an organic material, for example an oxygen-containing organic material, to form a carbonaceous layer on the surface thereof prior to use of the catalyst in oxidative dehydrogenation.

Abstract: A body board is provided having upper and lower plastic components defining an outer plastic shell having a hollow interior. The underside of the plastic shell defines a pair of runners which serve to space handholds disposed about the periphery of the body board from the ground on which the body board rests. A fiberglass reinforcement structure having upper and lower sheets is disposed within the hollow interior. The fiberglass sheets are bent or curved across the width of the body board to provide increased structural support for resistance to deflection or sagging of the body board when supporting a patient. The thickness of the upper and lower plastic shell components and the thickness of the upper and lower sheets of the fiberglass reinforcement structure are substantially uniform over a central x-ray region. Also, none of the upper and lower plastic shell components or the upper and lower fiberglass sheets extend vertically over any portion thereof disposed within the central x-ray region.

Abstract: Methods and an apparatus for measuring gas flow with greater reliability than earlier single-rotor and double-rotor turbine meters and dual turbine meter systems are disclosed. The apparatus comprises two independent rotors, in close proximity of each other, housed in the same meter body, but isolated from the effects of each other. No pressure and temperature correction are needed for accuracy performance comparison between the two rotors. Because of the two rotor averaging technique, the reliability of the volume totalization is greatly improved over earlier double-rotor and single-rotor designs.
