Abstract: This invention is a safety mechanism that improves upon existing inventions in the field of barbeques and grills by minimizing grill fires and/or burning or overcooking of one's food. A barbeque includes a control panel that receives input from one or several thermocouples installed inside the grill. In the event of a grill fire, the thermocouples detect the high heat, send a signal to the control panel, that in turn activates a mechanical lift to move the barbecue's cooking-grid away from the flame.

Abstract: The present invention relates to a turning type charcoal roast board, and more particularly, to a turning type charcoal roast board, wherein if exchange of a used roast board is required during roast of meat using a charcoal fire, new roast rods are placed at an opening of a main body of the roast board in such a manner that the roast rods stored in a roast rod-supplying box are fed via a moving means through users simple operation of a control device for controlling the feeding of the roast rods installed on a main body of the charcoal roast board, and roast rods used at the opening of the main board are transferred to and received in a roast rod-receiving box by means of rotation of the moving means. According to the present invention, the roast board can be rapidly exchanged to prevent meat from being burned, and it is possible to eliminate inconvenience in use due to frequent exchange of roast boards.

According to the invention, the capillary tubes of the register-type arrangement are placed into contact with the surface of the thermally-insulating insulation core, and the thermally-insulating insulation core is attached to the sheet metal panel by means of an elastic adhesive layer, whereby the capillary tubes are at least partially embedded into the adhesive layer between the sheet metal panel and the insulation core.

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 cooperatively 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 wick holder further engaging said capillary pedestal in such a locking manner as to resist accidental removal from said pedestal.

Abstract: A heater for a liquid has a combustion chamber, a jacket for the liquid extending about the combustion chamber and a burner head assembly connected to the combustion chamber. The burner head assembly includes a housing having a burner mounted thereon and a hollow interior. A control module and a fan are mounted in the hollow interior, the fan being connected to an electric motor. A compressor and a fuel pump are mounted on the housing and are operatively connected to the electric motor. The control module may include controls for exercising components of the heater prior to combustion, thereby verifying operation of these components. Preferably there is a speed control for the motor, such as a closed loop speed control which regulates motor speed and accordingly output of the heater. Preferably there is a backup system using a lookup table in the event that the closed loop speed control fails.

Abstract: A battery powered ignition and control system for a gas burner includes circuits for controlling a pilot burner, a main burner, a flame sensor and an igniter. Mechanically latched valves, which require power only to switch between and open and closed state are used to control the pilot and main gas. The circuitry spends a majority of time in a powered down state and draws power only when required to interrogate the state of the flame and to perform an ignition sequence as required, as periodically dictated by a watchdog system. The latching valves are electrically pulsed to change state and thus draw very low average power when called upon. Lithium batteries provide system power for a long duration.

Abstract: With the disclosed device, some or all of the available oil tank vent gas in a production system can be utilized to augment the primary fuel gas needed by a heater treater unit to separate the gas, oil, and water fractions from raw natural gas extracted at the wellhead. Augmenting the primary fuel gas with vent gas reduces the demand for primary fuel gas, which thereby increases the amount of gas traversing a meter. The disclosed device also provides for an auxiliary burner unit that can directly address any available oil tank vent gas that is not utilized to augment fuel gas as waste gas. A method and apparatus for reducing the venting of raw natural gas emissions from an oil storage tank is described.
