A first length extends away from the spiral section to the fold and along a first imaginary plane, and a second length extends from the fold to the spiral section and along a second imaginary plane. A wrapped section has a shape including at least one contour conforming shapes of the spiral and folded sections.

Abstract: An ultralight stove comprises a fuel reservoir having a plurality of jet holes in the top through which vaporized fuel escapes and burns, a portion of which is directed toward a heat conducting heat transfer plug, heat from which being conducted through the heat transfer plug to the reservoir where it heats fuel in the reservoir causing increased fuel vaporization that pressurizes the reservoir which in turn causing pressurized fuel to escape through the jet holes resulting in increased heat to the heat transfer plug, the cycle continuing until a fuel consumption and temperature equilibrium is obtained where the heat transfer plug and reservoir reach maximum operating temperatures. An external fuel absorber on the reservoir top receives fuel which when ignited initially heats the heat transfer plug to initiate stove operation.

Abstract: A gas stove with a burner and gas container is configured such that the gas container is thermally conductively connected with a burner part that is heated during operation. The thermally conductive connection is achieved via a thermally conductive housing that accommodates the gas container. This ensures a reliable burner operation despite an endothermic gas expansion in the gas container.

Abstract: A butane fuel supply container for a cooking stove, the container has a thin side wall held rigid by the vapor pressure of the fuel, but the side wall can be finger deformed when the can has been depressurized or hand crushed with the exit valve of the container open, the vapor therein being expelled as the container is deformed or crushed. The vapor tube has a vapor entrance in the vapor pocket above the pool of liquid fuel when the container is correctly oriented in the stove. The vapor tube passes vapor through a valve at the dome of the container.

Abstract: A gas operated lantern includes a regulator having a simple mechanism allowing a user to start or stop the flow of gas through the regulator. The regulator preferably exhausts an air/gas mixture in the same direction as which gas enters the regulator. The regulator includes a diaphragm assembly which presses down on a valve assembly to open the valve assembly. A stem enters the regulator and is turnable by the user to raise the diaphragm assembly and thus cause the valve assembly to close. The lantern also includes an automatic choke. The choke is preferably a strip of metal located in the burner tube of the lantern which acts to close off a portion of the burner tube when the lantern is cold, causing the air/fuel mixture to become richer and thus easier to light. As the lantern heats up, the choke straightens to open the burner tube, allowing a greater flow of air through the lantern and causing the air/fuel mixture to become leaner and thus raising the efficiency of the lantern.

Abstract: In a high-calorie gas appliance (1) which is set with a replaceable fuel gas cassette (9) containing therein liquefied gas and has a burner (7) for burning vaporized fuel gas from the cassette, a heat transfer plate (15) is mounted on the gas appliance with its one end portion disposed near the burner (7) and its the other end portion in contact with the fuel gas cassette (9) so that a part of heat of combustion at the burner (7) is transferred to the fuel gas cassette (9) to heat the same. Further, a heat accumulator member (2) is disposed in contact with the heat transfer plate (15) in the position of contact of the heat transfer plate with the cassette (9). Thus temperature drop of the liquefied gas due to vaporization latent heat in response to gas supply from the cassette is suppressed, thereby ensuring stable gas supply even if the amount of gas in the cassette upon initiation burning is reduced and ensuring exhaustion of the cassette upon quenching.

Abstract: A spark igniter mechanism is provided for a torch having a burn tube. The spark igniter mechanism includes a one-piece housing and an igniter which is held against the burn tube by the housing. The igniter includes a spark wire which extends through an opening formed in a wall of the burn tube. The spark igniter mechanism further includes a fastener which secures the housing is to the burn tube. In addition, an adhesive may help to further secure the housing to the burn tube. The spark igniter mechanism of the present invention facilitates the use of a single igniter design with a plurality of torches. Furthermore, the mechanism is inexpensive to manufacture and assemble.

Abstract: A burner including a storage tank, a gas outflow means, a pressure regulating means, a control means, a hood, a selectively replaceable gas ejecting base, a gas diffusion burner head and/or a firing means. When in use, a control knob is firstly turned so that fuel gas flows along a gas path to escape from the gas diffusion burner head and/or the firing means. Then a push-button is pressed so that a piezo-electric device generates electrostatic sparks to ignite fuel gas escaped from the gas diffusion burner head and/or the firing means. The intensity of the fire may be adjusted by means of the control means. A handle is also provided to facilitate carrying.

Abstract: A gas lighter having a tank made of a synthetic resin, a burner including a nozzle and a wick member wherein the nozzle has a lower side portion containing a porous member and a through hole therein, And a metal heat collecting member extending into the tank and having a projection inserted in the through bole of the porous member.

Abstract: The invention provides a combustion device such as a stove which may include a pressurized fuel mixture, such as an aerosol container containing alcohol and a propellant which may comprise a normally gaseous hydrocarbon, such as a liquified petroleum gas. The propellant and air are fed to a combustion zone as a combustion mixture, which is combusted therein in a cold start period to pre-heat the liquid fuel and vaporize it. When the liquid fuel is vaporized by the heat provided by combusting the propellant gas, combustion is continued by combusting the vaporized liquid, e.g., alcohol, fuel. The pressurized fuel composition may comprise a major proportion of alcohol together with a minor proportion of the hydrocarbon propellant starter fuel. The method therefore includes carrying out an initial, cold-start phase of combustion utilizing the propellant as fuel, and a subsequent stage of combustion utilizing the vaporized liquid fuel.

Abstract: A lighter having a body bounding a liquefied gas reservoir and an exhaust chimney through which the gas issues to the outside when a lid is opened. The lighter has a gas rate-of-flow limiter in the form of a tube of a length greater than 5 mm and of a very reduced flow cross-section between 0.03 and 0.002 mm. The tube is disposed in the reservoir and is fitted hermetically in the body either directly or with the interposition of a support member.

Abstract: The present invention is drawn to a self-priming alcohol stove comprising a burner cup with a base and side walls for storage of liquid alcohol, a main burner attached to the burner cup, a start-up burner, and a heat transfer unit to transfer heat from the main burner and/or the start-up burner to a quantity of alcohol held by transfer unit within the burner cup at a location distal from the side walls and the base. The vaporized alcohol passes to the main burner and is ignited by flames from the start-up burner. More alcohol is then continuously absorbed from the burner cup by the wick between the concentric, cylindrical walls to maintain the main burner flame. Operation of the main burner substantially deprives the start-up burner of oxygen so that heat from the main burner vaporizes alcohol absorbed between the concentric walls.

Abstract: A heater, particularly for emergency use in a car or other vehicles is designed to use solid paraffin wax fuel. The heater has a housing containing a combustion chamber and burner. A vent duct is angled outwardly from the housing and both provides combustion air and permits exhaust of combustion products. The vent duct can be inserted through a window opening in a vehicle so that interior air is not consumed or contaminated when the heater is in operation.
