  • Patent number: 6135759
    Abstract: Variable-heat chafing-dish burners and methods of use. One variable-heat chafing-dish burner embodiment has a reservoir with liquid fuel, into which a short wick and a long wick extend. Both wicks are lit initially, in order to provide initial high heat to bring chafing-dish water quickly to temperature. As fuel is consumed by the flames fed by both wicks, the fuel level within the reservoir drops. The short wick initial immersed length is set such that at the approximate time the chafing-dish water has been brought to temperature, the short wick is no longer immersed in fuel, and the flame it fed is extinguished due to fuel starvation. After the flame fed by the short wick is extinguished, only the flame fed by the long wick remains lit, thereby providing the lowered heat required to maintain the chafing-dish water at temperature. In this manner, a high initial heat is provided to bring chafing-dish water quickly to temperature, and lower heat is provided thereafter to save fuel.

    Abstract: The wick-interrupt temperature controlling heat pipe (WITCH) is a device for controlling the temperature of spacecraft temperature-sensitive, heat dispensing devices. A heat transporting working fluid is conveyed in saturated equilibrium with its vapor across a discontinuous internal capillary liquid wick, within a tubular cylindrical pressure vessel, from a condenser section to an evaporator section located on either side of the discontinuity. When the temperature within the WITCH rises to a predetermined level, a sliding wick located within the internal capillary liquid wick is inserted across the discontinuity by a temperature sensitive control rod, thereby allowing the heat transporting working fluid to circulate from the condenser section wick to the evaporator section wick. In this configuration, the WITCH operates identically to the "constant-conductance heat pipe" commonly used.

  • Patent number: 4793321
    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.
