Abstract: A portable heater adapted for use in a recreational enclosure or temporary work enclosure includes a housing having an air inlet on the lower front face. A gas supply is at least partially enclosed by the housing which provides propane to the mouth of a burner venturi located within the housing. Air is drawn through the air inlet and also enters the mouth of the burner venturi. The air and gas are mixed thoroughly as they travel upwardly through the burner venturi. A chimney effect increases fresh air flow velocity into the burner venturi and allows the heater to operate at a reduced fuel gas pressure. Upon exiting the burner venturi, the air/gas mixture is to a plenum and radiant surface where combustion takes place. Any conventional means may be provided to ignite the air/gas mixture in order to cause combustion. The combustion products deflect off a deflector, which is cooled on a rear face by air flow through the housing, which decreases the temperature of the combustion products before exiting an outlet.

Abstract: In summary, therefore, the inventive method and apparatus enables one to mount and dismount an implement, such as a snow plow, from a vehicle, such as a pickup truck, with a heretofore unknown simplicity. The method mounting the plow basically comprises the steps of driving the vehicle toward the blade assembly until the frame assembly mounted on the front of the vehicle is in operative proximity to the blade assembly. Generally, that proximity is established by just touching the blade assembly with the frame assembly.

Abstract: Co-Ion exchange of the interlayer cations of a layered silicate with a mono-protonated aromatic diamine and an alkyl ammonium ion into the silicate galleries. The presence of the alkyl ammonium ion provides low oligomer melt viscosity during processing. The presence of the diamine allows chemical reaction between the silicate surface modification and the monomers. This reaction strengthens the polymer silicate interface, and ensures irreversible separation of the individual silicate layers. Improved polymer thermal oxidative stability and mechanical properties are obtained.

Abstract: The method of folding overlap side edges of a wide breaker ply over side edges of a narrow breaker ply wrapped around the wide breaker ply on circumferentially spaced modules wherein the modules have axially movable belt lifting and conveying nose members to carry the overlap side edges of the wide breaker ply axially over the side edges of the narrow breaker ply and position the wide side edges of the wide breaker ply over the narrow breaker ply side edges. The nose members are then retracted to peel the belt away from the folded overlap side edges of the wide breaker ply.
