  • Patent number: 6129818
    Abstract: In a method of and apparatus for manufacturing methanol from methane a catalytic area is formed on the exterior of a hollow sintered stainless steel tube. Methane is maintained within the sintered stainless steel tube at predetermined pressure, and water continuously flowing across the exterior surface thereof strips the methane forming sub-micron sized methane bubbles. Light energy is directed onto the catalytic surface to form hydroxyl radicals from the flowing water. The hydroxyl radicals cleave the carbon-hydrogen bonds of the methane to form methyl ions which combined with the hydroxyl ions to form methanol.

  • Patent number: 6113747
    Abstract: In a method of and apparatus for manufacturing methanol from methane a catalytic area is formed on the exterior of a hollow sintered stainless steel tube. Methane is maintained within the sintered stainless steel tube at predetermined pressure, and water continuously flowing across the exterior surface thereof strips the methane forming sub-micron sized methane bubbles. Ultraviolet light energy is directed onto the catalytic surface to form hydroxyl radicals from the flowing water. The hydroxyl radicals cleave the carbon-hydrogen bonds of the methane to form methyl ions which combined with the hydroxyl ions to form methanol.

  • Patent number: 6103130
    Abstract: In a method of removing organic contaminants from a liquid, an oxidizing gas is formed into sub-micron size bubbles which are dispersed into a flowing initially contaminated liquid, after which the treated liquid is recovered. The oxidizing gas is preferably selected from a group including ozone and chlorine dioxide and is utilized immediately upon its manufacture.

  • Patent number: 4967596
    Abstract: An apparatus for indicating the peak tangential velocity of a swung sporting goods implement such as a tennis racquet, golf club, or baseball bat, comprises a tube having a longitudinal bore. A seismic mass is slideably disposed within the bore of the tube, and a spring operates to pull the seismic mass toward the proximal end of the tube. A reset mass is normally captured at the distal end of the tube but is selectively released to slide within the bore of the tube. A peak velocity indicator is slideably disposed within the bore of the tube between the seismic mass and the reset mass, the peak velocity indicator frictionally engaging the inner walls of the tube such that it is displaceable longitudinally within the bore of the tube by an applied force but maintains its position within the bore of the tube once the applied force is removed.
