Abstract: A performance enhancement device for motor fuels. The device include a filter canister which is positioned in the vehicle fuel line. The filter canister includes a quantity of catalytic metals which include tin, antimony and lead. As the fuel passes through the filter canister and contacts the catalytic metals, which must be attached to a metallic mesh by binders, the molecular structure of the fuel is reorganized. Fuels so treated exhibit higher combustibility, which results in greater fuel economy and reduced exhaust emissions.

Abstract: An air cleaning device for attachment to a toilet bowl comprises a bracket mounted on the bolts behind the toilet seat and extending outwardly to one side. At the end of a bracket is mounted a cradle into which a housing is mounted including a fan housing and a filter assembly. The filter assembly is carried on the underside of the fan housing and includes a cage having a closed base wall and a plurality of vertical bars for the air enters the interior of the cage and escapes horizontally through the bars. A sleeve-shaped filter element is mounted over the bars and sits on the horizontal base. Vertical power supplied by a battery pack which can slide in and out of a receptacle on the top cover of the housing. The housing includes a nozzle which can slide in and out of a receptacle in the housing, the nozzle being formed in the shape of a flat tube so as to extend over the toilet bowl.

Abstract: Variable flow of either primary air or of a mixture of primary and secondary air is provided to an enclosure by an air diffuser adapted for installation in an opening in the enclosure. Sleeve means is movably mounted within a housing of the air diffuser for movement between a closed position in which apertures of the housing are closed by the sleeve means and an open position in which they are open. Actuator means is engageable with the sleeve means for selectively moving the sleeve means between the closed and open positions and to positions therebetween so as to discharge a desired proportion of primary air through the apertures into a plenum to bypass the enclosure. Deflecting means is mounted on the housing for deflecting the primary air outwardly as it is discharged into the enclosure. The sleeve means may extend downward toward the deflecting means such that a passage of variable area is formed to further direct the primary air through the apertures.

Abstract: A method for purifying air by removing gaseous formaldehyde under ambient conditions, by bringing the air in contact with a solid shaped composition consisting essentially of one or more polyhydric water-soluble polymers and ambient moisture, in the absence and in the presence of a solid substrate.
