Abstract: A cooking sensor system that includes a burner assembly; and a vibration sensor assembly configured to generate a vibration signal that corresponds to vibrations of cookware situated on the burner assembly. The cooking sensor system also includes a processor to receive the vibration signal and determine at least one of a boiling condition and a boil-dry condition for a liquid contained within the cookware, wherein the determination is based at least in part on the vibration signal. The cooking sensor system further includes an indicator element coupled to the processor to indicate the at least one of a boiling condition and a boil-dry condition. The cooking sensor system may also include a control element coupled to the processor to operate the burner assembly based at least in part on the at least one of a boiling condition and a boil-dry condition.

Abstract: Systems and methods for controlling gas to gas-fired appliances are disclosed. An illustrative system can include a modulating gas valve adapted to supply gas to a burner unit, an inducer fan adapted to produce a combustion air flow at the burner unit, a pressure reducing element in fluid communication with the gas valve and adapted to output at least one pressure signal for sensing the combustion air flow outputted by the inducer fan, and a controller for controlling the speed of the inducer fan. The pressure reducing element can include a venturi tube, flow nozzle, or other suitable device capable of producing pneumatic signals that can be used by the gas valve to modulate the gas supplied to the burner unit. By pneumatically linking the gas valve to the actual combustion air flow, the gas valve can be operated over a wide range of firing rates by adjusting the speed of the inducer fan.

Abstract: Self contained and transportable camp heater with a burner within a casing and a fuel tank operably connected to the burner. A stack is removably mounted on the casing and is positioned on a holder with the casing and the fuel tank after removal for transportation purposes. A regulator is operably connected to the fuel tank and, thence, to the burner. The regulator is conveniently a zero pressure regulator.

Abstract: A wax candle (10) positioned below a wax reservoir (30), which is held in position above candle (10) by a wax reservoir support (20). While burning, the heat emitted from the flame of candle (10) causes the wax contained in reservoir (30) to slowly and continuous melt. This melted wax drips down from reservoir (30) into candle (10) and replenishes the wax used for combustion on the wick of candle (10). The rate of this replenishment and the flame size of candle (10) are self regulating, and in direct relationship with each other during cycle outlined below: An increase in flame size causes a subsequent increase in replenishment. An increase in replenishment causes a subsequent decrease in flame size. A decrease in flame size causes a subsequent decrease in replenishment. A decrease in replenishment causes a subsequent increase in flame size. And the cycle begins again.

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).
