The torch tip can be used to simultaneously heat a plurality of closely spaced pipes for ease of removal or attachment to an object such as a reversing valve.

Abstract: A disposable lighter holder includes a holder frame providing a sliding chamber therein, a lighter holder for holding a disposable lighter in position slidably disposed in the sliding chamber, a resilient element connected between the holder frame and the lighter holder to normally urge and retain the lighter holder in a lower position, and an ignition member being arranged in such a manner that when a pushing force is applied by an adult's thumb on the pusher member in order to drive the lighter holder sliding frontwardly along the sliding chamber, simultaneously, a gas lever of the disposable lighter is depressed by the ignition member for releasing gas and a striker wheel of the disposable lighter is struck by the ignition member to rotate for generating striking sparks to ignite the releasing gas.

Abstract: A hand operated fire starting tool for use as a survival aid and in general outdoor activities such as camping. The tool includes a case, a pyrophoric element mounted to the case for reciprocal and rotational movement between a stored position and an operating position. It also includes means such as a spring for biasing the element toward the operating position and a striker which may be engaged with the element. The tool also includes a cap which is both pivotally and slidably mounted to the case for releasingly securing the element in its stored position.

Abstract: A low NOx gas burner for heating objects having a supply of gas under pressure which is to be mixed to achieve a combustible mixture, gas flow line connecting to said burner to said supply, a burner means for mixing air with said fluid fuel to achieve said combustible mixture, characterized by said burner means includes one or more jet forming means for issuing one or more jets of said gas having a given cross-sectional area and sweeping said one or more jets of gas in ambient air downstream of said burner means to mix air with said gas and achieve said combustible mixture a distance spaced from any physical structure of said burner means whereby a flame front of burning combustible mixture has a broad shape and is spaced a predetermined distance from said burner.

Abstract: An oxygen welding apparatus capable of generating its oxygen needs without an external oxygen source from a self-contained solid state electrolytic cell which separates oxygen from the air. The cell employs a flexible, ductile ceramic composite as the solid electrolyte. The ductile ceramic composite electrolyte comprises a continuous, ordered, repeating, interconnected ductile metallic array substantially surrounded by and intimately integrated within a ceramic matrix. The cell is connected to a power supply so when current is passed through the cell, oxygen or nitrogen is separated from the air passing through the cell.

Abstract: A nozzle assembly for use in a hot air torch wherein the hot air torch utilizes a source of compressed air and a source of gaseous fuel. The hot air torch has a handle portion which holds a first pipe carrying pressurized air and a second pipe carrying propane under pressure. The first pipe containing pressurized air splits into two passageways, each passageway having a valve with which flow can be regulated. As propane travels through the second pipe to an exhaust outlet nozzle, pressurized air travels into a burner tube and an annular plenum surrounding the burner tube. The burner tube has circumferentially spaced openings. The compressed air from the plenum goes through the openings and travels radially inwardly toward the exhaust nozzle. The exhaust nozzle has a generally frusto-conical shaped exterior side surface to present a frusto-conical surface against which air jets from the circumferentially spaced openings in the burner tube impinge.
