  • Publication number: 20030056390
    Abstract: A portable air heating system for use in remote areas is disclosed. The portable air heating system provides a stream heated air for use in heating the interior of a structure, such as a tent or camp trailer. The heating system generally comprises an air transfer assembly for providing a flow of air through the system, a fuel burner assembly for providing heat by combustion, and a heat transfer housing for safely transferring the heat produced by the fuel burner assembly to the air flowing through the transfer assembly. The burner assembly and the heat transfer housing are both positioned outside the area being heated. Further, the exhaust gases are completely isolated from the air heated by the system, thereby virtually eliminating the likelihood of asphyxiation by the exhaust gases from the burner. The present heating system is also highly portable and simple to use, thereby providing an efficient mechanism for providing heat where more traditional heating apparatus are not readily available.

  • Patent number: 6270584
    Abstract: Method and apparatus for cleaning and/or drying objects that may have been wetted or contaminated in a manufacturing process. The objects are submerged in a rinse liquid in an enclosed chamber, and aerosol particles from a selected liquid are introduced into the chamber above the rinse liquid surface, forming a thin film on this surface. As the rinse liquid is slowly drained, some aerosol particles settle onto the exposed surfaces of the objects, and displace and remove rinse liquid residues from the exposed surfaces by a “chemical squeegeeing” effect. Surface contaminants are also removed by this process. Chamber pressure is maintained at or near the external environment pressure as the rinse liquid is drained from the chamber. Inert gas flow is employed to provide aerosol particles of smaller size and/or with greater dispersion within the chamber. Continuous filtering and shunt filtering are employed to remove most contaminants from the selected liquid.
