Abstract: A disposable liquid fuel burner is disclosed which comprises a container having a closed bottom, an enclosing sidewall and an open top and at least partially filled with a liquid fuel. A flat support member is supported adjacent the open top above the liquid fuel and having a centrally located opening receiving one end of an elongated wick of a fibrous material overlying the support member and having its other end immersed in the liquid. The support member may be a cardboard or plastic disk supported on legs or a cylinder or may be a cup-shaped member. A fibrous bat of a refractory, non-combustible material substantially fills the open top and overlies the support member and the end of the wick supported thereon. A bat of a plastic, e.g., polyurethane, foam material overlies the fibrous bat. A top cover is secured on the container closing the open top and is at least partially removable, e.g.

Abstract: In order to improve an apparatus for the evaporation of active ingredients such as pyrethrum or similar insecticides, air-improving, bactericidal, disinfecting and/or, for example, curing substances incorporated in cellular boards or other solid carrier materials, consisting of a housing in which there is provided a heating means which is arranged behind a housing window, and of a holding means for the exchangeable arrangement of an active ingredient carrier panel in front of the housing window in such a way that an evaporation apparatus which is independent from electrical energy can be achieved while maintaining high reliability in handling, it is proposed that a catalytic, merely glowing, that is flamelessly acting burner 4 with fuel tank 3 be arranged in the housing 1 having ventilation openings 13 at such a distance from the housing window 2 that the hot waste gases from the burner 4 flow through the housing window 2 and activate the active ingredients.

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 catalyst moving structure for an oil burner capable of facilitating handling of the oil burner in the manufacturing and maintenance as well as covering a combustion gas discharge opening of a combustion cylinder construction of the oil burner when a wick operating shaft is rotated to a fire-extinguishing position, to thereby effectively preventing discharge of bad odor during the fire-extinguishing operation. The catalyst moving structure includes a catalyst moving mechanism including a vertically movable sliding shaft and a connecting rod pivotally mounted on the sliding shaft, a catalyst support member mounted on the sliding shaft, and a movement transmission mechanism including a cam device fitted on the wick operating shaft and a push-up lever operatively connected between the cam device and the connecting rod to transmit actuation of the wick operating shaft to the connecting rod to vertically move the sliding shaft.

Abstract: In order to improve an apparatus for the evaporation of active ingredients such as pyrethrum or similar insecticides, air-improving, bactericidal, disinfecting and/or, for example, curing substances incorporated in cellular boards or other solid carrier materials, consisting of a housing in which there is provided a heating means which is arranged behind a housing window, and of a holding means for the exchangeable arrangement of an active ingredient carrier panel in front of the housing window in such a way that an evaporation apparatus which is independent from electrical energy can be achieved while maintaining high reliability in handling, it is proposed that a catalytic, merely glowing, that is flamelessly acting burner 4 with fuel tank 3 be arranged in the housing 1 having ventilation openings 13 at such a distance from the housing window 2 that the hot waste gases from the burner 4 flow through the housing window 2 and activate the active ingredients.

Abstract: An alcohol outdoor portable stove for hunters and fisherman comprising a hollow firebox with a cutaway portion in the front wall thereof for allowing escape of heat forwardly of the stove, a removeable front panel which covers the cutaway portion and a hinged lid for the top of the stove, an alcohol container, an arrangement inside the firebox on the floor thereof for supporting the container in an upright position to prevent accidental tipping over thereof and a manually operable heat regulator for controlling the air supply to the container for regulating the heat put out by the stove, whereby, upon lighting of the alcohol in the container, heat in copious amount will escape from in front of the stove and provide ample warmth for the hunter or fisherman.

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.

Abstract: A fuel cartridge for heating food trays uses a liquid fuel and a wick. The cartridge has a container that holds the fuel and has a lid with an aperture formed in it. A flat rectangular fiberglass strip serves as the wick and is pressed against the lower side of the aperture. The lower ends of the wick extend into the fuel, and the central portion of the wick protrudes only slightly from the aperture. A metal ring can be used with the container to block wind currents.
