Abstract: A system for repelling insects from an outdoor area includes at least one torch configured to disburse an insect repellant by burning a fuel, and a central fuel reservoir interconnected with the torches by a fuel plumbing system and configured to automatically replenish the fuel in a local reservoir of the torch. Fuel can be gravitationally transferred from the central reservoir to the torches, or maintained under pressure in the plumbing system and controlled by level sensors and valves in the torches. A remotely operated wick seal can exclude air from torch interiors and prevent fuel spills. A central controller and/or local torch controllers can be powered by wires and/or by batteries, which can be recharged by solar power. The controllers can be wirelessly monitored and/or controlled by software running on a remote device. The remote device and software can control a plurality of the systems.

Abstract: The present invention provides a combustion device, which includes a fuel tank assembly and a candle wick. The fuel tank assembly includes a first tank, a second tank, a connection tube, and a switch. The capacity of the second tank is less than the capacity of the first tank. An end of the connection tube is connected to the first tank, and another end of the connection tube is connected to the second tank. The connection tube communicates with internal spaces of the first and second tanks. The switch is disposed between the first and second tanks so as to selectively open or close a channel interconnected between the first and second tanks. The candle wick is mounted in the second tank. Therefore, the combustion device is easy to use by the above structure.

Abstract: A hanukiah that includes a base, eight oil holders and a ninth one that serve as a shamash. Each of the oil holders is shaped as a hollow cup that has a top opening and a narrower hollow leg that includes two opposite horizontal holes. The oil holders are designed to receive oil for lighting a wick. The base includes nine vertical holes which are designed to receive the narrow hollow legs in a way that enables them to rotate inside. The vertical holes are connected together by a horizontal pipe. The user may pour oil into the shamash oil holder and by that to fill the other oil holders. The user may turn one of said oil holders to determine how many of them will be filled by oil.

The device includes a thin metal member formed on the pad and including an intermediate conductive member, a forward conductive section extended from the conductive member, and a rearward conductive section extended from the conductive member, and a heater unit fastened in a space defined by the recess. The heater unit includes a fuel chamber, a combustion chamber filled with zirconia fibers, and a channel interconnected the fuel and the combustion chambers, the channel including fibers and a wick having one end immersed in the fuel chamber and the other end connected to the fibers.

Abstract: A liquid fuel lamp for burning fuel comprises a plurality of wicks. The lamp has a fuel tank for initially receiving the liquid fuel, a plurality of reservoirs, each holding a wick, and at least one conduit. The conduit is in fluid communication with at least one respective reservoir and the fuel tank, and carries the liquid fuel by way of gravitational force to the reservoir, with which the reservoir forms a housing for the wick. Thus, fuel may distributed to all reservoirs and wicks from a central tank into which fuel is deposited.

Abstract: An apparatus for producing a sustained flame, comprising: an inner wick with a hollow center; an outer wick disposed around the inner wick, wherein the region between the inner wick and the outer wick defines an inter-wick region, and wherein the region around the outer wick defines an outer wick peripheral region; at least one fuel reservoir, for containing a flame-fueling liquid, in communication with at least one of the wicks; a first air container; a first air channel connecting the first air container to the center of the inner wick; and a second air container.

Abstract: The present invention provides various embodiments for a colored flame lamp and a colored flame candle. The lamps and candles may burn with a flame of a characteristic color such as green, red, blue, purple, orange, or silver-white. The lamp fuel composition may include a liquid solvent and dissolved metal salts. The candles may be composed of a solvent, a hardener, and metal salts dissolved in the solvent. The colored flame in the lamp and candle results from vaporized metal salts that travel up a wick with lamp fuel or melted candle material.

Abstract: A safety device for preventing uncontrolled burning in barometric-type liquid fuel burners of the type where a removable fuel tank (60) feeds a fuel chamber (40), which supplies the fuel to a wick (54), via a sump opening in the upper surface of the chamber (40). A fusible link (28), which is affixed to a tank guide (12) via a support (30), is connected to an arm (74). The arm (74) is in turn connected to a lever (78) in a hinged fashion. The lever (78) is attached to a support (82) in a hinged fashion. A face (80) is present on the lever (78) at the end of the lever (78) distal to the end connected to arm (74). The face (80) is proximate to an automatic wick extinguishing unit (42). Should the temperature of fusible link (28) exceed a predetermined level, it will open irreversibly, allowing arm (74) to move downward, which in turn causes lever (78) to rotate about support (82), forcing face (80) upward, which actuates the automatic wick extinguishing unit (42).

Abstract: A safety device for preventing uncontrolled burning in wick-fed liquid fuel burners of the type where a removable tank (60) feeds a fuel chamber (40), which supplies the fuel to a wick (54), via a sump opening in the upper surface of the chamber (40). A plate (32) in the removable tank (60) contains a seat (90) and a needle (76), which, in conjunction with a compartment (80), a float (88), a lever (82), and an orifice (34), restrict fuel egress from the tank. A fill tube (44) traverses the plate. An opening (104) in the plate, along with a face (102) attached to an arm (96), allows air egress from a chamber (30) in the tank during fueling of the tank, but prevents fuel egress from the chamber when the tank is inserted in the burner. Fuel flow through the plate (32) is regulated by the movement of a float (88) attached to a lever (82), which is operatively connected to a needle (76) and a seat (90). Fuel flows through a seat (90) into a compartment (80), and begins to egress through an orifice (34).

Abstract: A safety device for preventing uncontrolled burning in wick-fed liquid fuel burners of the type where a removable tank (60) feeds a fuel chamber (40), which supplies the fuel to a wick (54) via a sump opening in the upper surface of chamber (40). A gasket (76) contains vapors present in the sump area when the tank (60) is seated in the sump opening. When the tank (60) is removed from the sump opening, a plate (84) moves upward due to the action of a spring (82) and contains vapors in the sump area.

Abstract: A liquid fuel burning apparatus having a system for interrupting operation of the apparatus during refueling. The apparatus has a spring biased cable mounted at one end within a slot located proximate a refueling opening. A fuel tank cap has a projection which is adapted to contact a portion of the cable disposed within the slot. When the cap is fully seated on the refuelling opening of the fuel tank, the cable is depressed within the slot by the projection. When the cap is removed, the biasing device causes the cable to move to a released position. For example, this movement of the cable in a specifically disclosed heater embodiment is transmitted via the cable to a wick retracting mechanism which responds by lowering the wick into the reservoir and extinguishing any flames.

Abstract: A heating device, especially a motor vehicle heating device operated by means of liquid fuel, has a vaporization burner with an absorbent body that can be acted upon by liquid fuel. To effect equalization of heat distribution and fuel pretreatment, there is provided a cover of a high temperature and corrosion resistant sheet steel. The cover has a plurality of openings and covers at least a major portion of that surface of the absorbent body which faces a combustion chamber of the heating device. When the absorbent body has a through-opening to promote vaporization of the liquid fuel, the cover likewise can have a through-opening coordinated thereto, thus exposing the through-opening.
