Publication number: 20040106080Abstract: 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 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.Type: ApplicationFiled: October 2, 2003Publication date: June 3, 2004Applicant: MR.

Patent number: 4317986Abstract: An electrically heated convertible tool for removing a golf club head from a shaft inserted in the hosel of both metal and wooden golf club heads includes a pair of plier-like pivotally connected opposed jaws each carrying an electric heating block. The heating blocks are disposed in opposed clamping relationship and are each provided with an arcuate recess sized to closely engage and heat the tapered hosel surface of a metal golf club head. The blocks are adjustable relative to each other to accomodate for size variations in hosels. An elongated heat exchange member having a head sized to be clamped in the arcuate recesses of the blocks and an elongated linear portion sized to be insertable into the interior of a hollow metal golf club shaft is provided to permit use of the tool to heat the hosel of a wooden club head. The tool permits heat to be applied to the hosel of the club heat to soften the cement holding the hosel to the shaft of the golf club.Type: GrantFiled: June 12, 1979Date of Patent: March 2, 1982Inventor: Daniel A. Sullivan

Patent number: 4201544Abstract: A portable space heater features a tubular heat shield of generally uniform cross sectional configuration about and in longitudinally offset, concentric, closely spaced relation to a tubular shell defining its combustion chamber to project beyond a nose cone at its outlet end. The projection of the shield beyond the cone is limited to produce, upon a high velocity pressurized flow of air around the inner surface of and the length of the shield, distinctive flow of air within the projected end of the shield and about the nose cone the pattern of which produces an effective heat exchange with the products of combustion at the cone which substantially moderates the cone temperature.Type: GrantFiled: November 10, 1977Date of Patent: May 6, 1980Assignee: Keohring CompanyInventors: Eugene C.
