Abstract: A light-emitting device comprises a structure defining an orderly and periodic series of cavities of nanometric dimensions, in which a process of catalytic combustion is confined. The dimensions and/or the distance between the micro-cavities are selected to obtain a light emission in the visible and prevent and/or attenuate at the same time emission of infrared radiation.

Abstract: A candle assembly includes a support base, a melting plate having a capillary pedestal, a wick holder that fits onto the capillary pedestal, and a fuel element that fits over the wick holder. The wick holder includes a sleeve having first and second open ends. A wick fits into the sleeve and extends between the open ends. The sleeve has a constricted portion, which is disposed between the open ends and has a cross-sectional area less than any other cross-sectional area between the open ends. The constricted portion reduces an effective capillary fluid flow capacity of the wick between the open ends, which may thereby regulate how quickly fuel is consumed when the candle assembly is burning. A capillary well disposed between the wick holder and the capillary pedestal may be adapted to promote a successful relight after an initial burn of the candle assembly.

Abstract: A flame arrestor for a flowing explosive gas (4), having a flame barrier (10, 20, 30) with a large number of defined passage gaps (17, 18), whose gap cross section is set with regard to the properties of the flowing gas (4), is cooled effectively and secured against a flame flashback in the case of continuous combustion by the fact that second gaps (18) having a smaller gap cross section are arranged adjacent to the first gaps (17) having the selected gap cross section.

Abstract: Some embodiments of the present invention relate to a portable charcoal grill where, in the closed position, charcoal may be supplied through an opened chimney lid located at the top of the grill, and lit paper or other kindling material may be inserted through an opening to an ignition area located at the bottom of the grill in order to ignite the charcoal. The chimney effect created by the shape and directionality of the closed portable grill may aid in heating and igniting the charcoal. Once the charcoal is at the proper burning point, the portable grill may be safely opened up and a large grilling area may be available for cooking. The legs, which can be used as carrying handles for the grill, may be secured in place by a unique joint that has two or more distinct positions.

Abstract: A control device for controlling hydrogen flow of a hydrogen storage canister accommodated in a canister containing chamber includes a heating device which is connected to a heating fuel storage tank via a heating fuel supplying pipeline for conveying a heating fuel to a catalyst bed in the canister containing chamber and generating heat by combustion of the heating fuel at the catalyst bed. A blowing device provides an air flow to the canister containing chamber. A controller controls the operation of the heating device and the blowing device in correspondence to a temperature signal detected from an internal space of the canister containing chamber. The controller is coupled with a setting unit for setting various parameters which are stored in a parameter storage unit for controlling the controller.

Abstract: The present invention relates to melting plate candles which employ heat conductive elements to distribute heat from a burning flame at a wick to a support plate for a solid fuel and to the body of said solid fuel, so as to more rapidly liquefy the solid fuel, such as paraffin wax, and to more uniformly and intensely heat such fuels to increase the efficiency of consumption thereof and to more rapidly release volatile materials contained within said fuels. The heat conductive support plate is configured so as to have a capillary pedestal upon the surface thereof, which magnetically engages a wick holder comprising a preferably consumable wick and heat conductive fins which conduct heat from a flame upon said wick to said support plate, said magnetic engagement of said wick holder preventing accidental removal thereof from said pedestal. The fuel may be provided in various forms, configured to cooperatively engage said wick holder and support plate, and may comprise various volatile materials.

Abstract: A method and apparatus for controlling a candle flame. A candle flame may be provided in a controllable environment, e.g., an enclosed area formed at least in part by an air-tight cover. Air may be forced into the enclosed area by an air movement device (e.g., a fan) to keep the flame burning. The flame may be extinguished by reducing (e.g., stopping) air flow into the enclosed area.

Abstract: A disk-like piezoelectric lighter with a safety lock includes a casing, a gas emitting nozzle, a piezoelectric unit, a sliding member and a safety lock. The safety lock comprises an arcuate resilient arm; a sliding cap having an cover portion, a pair of stands, a pair of branch arms, a lateral blocking stopper and a guiding slot; a safety button which comprises a base portion and a button portion and which is mounted slidably in the guiding slot in such a manner that the base portion comes into contact with the resilient arm to allow the resilient arm to be shifted from the locked position that the resilient arm is blocked up by the blocking stopper to the unlocked position that the blocking up is released to ignite the piezoelectric lighter.

Abstract: A method of improving an individual artificial concrete log widely used in gas fires, the new concrete log(1) having at least one decorative ceramic fiber pad (1a) or (2a) secured in the cut out(2) section, the pad (1a or 2a) is positioned to mate with the contour of the concrete log (1). The decorative pad (1a or 2a) is installed to provide a secondary air chamber(3) between the back of the decorative pad (1a or 2a) and inner surface of the cut out (2). When the log is placed on an existing gas fire some of the gas flames are directed up through the secondary air chamber(3) creating flames coming out of the body of the composite concrete log(1) at the same time gas flames impinge the front decorative surface(6) of the installed ceramic fiber pad (1a or 2a) producing a radiant surface (6) simulating a real burning log thereby improving the overall visual effect of most existing gas log fire.

Abstract: A portable cooking kit, apparatus and method is usable for moderating heat from an intense heat source, such as an outdoor grill or 1. The apparatus includes a food support member, including a perforated panel surrounded by a rim. The food support member rests on top of a heat shield made from a heat-tolerant material. During use, the heat shield is stably suspended over direct, intense heat from a heat source. The food to be cooked is placed on the food support member, and the food support member may then be placed on top of the heat shield. By buffering the direct heat from the heat source, the heat shield allows food placed on the food support member to cook, but protects the underside of the food from becoming scorched. Optionally, a dome-shaped cover may be used to cover both the food support member and the heat shield.

Abstract: A piezoelectric lighter of model R with a safety device includes a casing, a storage, a gas emitting nozzle, a piezoelectric unit, a fixed cover, and a safety device. The safety device comprises a blocking stopper; an ignition cap having a cover, a guiding groove and a guiding aperture; a safety button comprising a button portion, a locking arm, a spring and a guiding retaining shaft that is movably arranged in the guiding aperture to push by the spring force the safety button right to form a locked position that the blocking stopper is located in the traveling way of the locking arm; only if the button portion is pushed left, the locking arm is moved away from the stopper to form an unlocked position that the blocking up is released to ignite the piezoelectric lighter.

Abstract: A torch assembly is provided, the assembly comprising: a container comprising an internal chamber for holding liquid fuel and an opening leading to the chamber; a wick having opposing ends, the first end is inserted through the opening and situated within the chamber, the second end projecting outwardly from the opening; a wick cap attached to the second end of the wick; a wick rod attached to the first end of the wick, the rod designed to be situated within the chamber of the container; and a snuffer cap designed to be attachable and detachable from the wick cap.
