| 20080257877 | Heat and/or Light Producing Unit Powered by a Lithium Secondary Cell Battery with High Charge and Discharge Rate Capability - A composition having a heating unit, lighting unit, or combination thereof that derives at least a portion of its operating or accessory power from an electric source that is a high capacity lithium secondary cell battery with a high charge rate. | 10-23-2008 |
| 20080260364 | Forced Air Heater Including On-Board Source of Electric Energy - A forced-air heater having a self-contained on-board electric-power supply that allows the forced-air heater to operate without an external electric power source; a fuel tank; a combustion chamber; a support; a housing including upper and lower housing portions; a motorized fan that during operation draws in ambient air through an air intake and forces air into the combustion chamber. | 10-23-2008 |
| 20100139651 | GAS-FIRED PORTABLE UNVENTED INFRARED HEATER - A portable radiant heater supplied by an associated fuel source comprises a housing having a handle for transporting the heater. A plenum in the housing receives fuel from the associated fuel source and mixes the fuel with air. A burner assembly includes a radiant surface that communicates with the plenum. A regulator limits the pressure of the associated propane source to approximately eleven inches water column, and an oxygen depletion system associated with the burner assembly automatically shuts off the heater at a predetermined oxygen content. A tank fitting with a position that can be adjusted relative to the regulator facilitates the installation of the associated fuel source to the heater. | 06-10-2010 |
| 20100147291 | Gas-Fired Heater with Environmental Detector - Provided is a portable heater supplied by an associated fuel source, comprising a housing, a fuel connection fitting, an orifice, a burner assembly, a regulator, a controller for selectively switching among operation states including at least a 4000 BTUs and a 9000 BTUs per hour state, a power source adapted to generate electrical power from heat, and a detector system adapted to use the electrical power generated by the power source, detect the level of a particular gas in the atmosphere, and interrupt combustion of the air-fuel mixture. A housing may comprise an air inlet and may define an interior region. A burner assembly may comprise a fuel valve adapted to control communication between the burner assembly and the associated fuel source, a venturi for mixing air and fuel into a fuel-air mixture, a combustion region adapted for the combustion of the air-fuel mixture to produce combustion products and heat. | 06-17-2010 |
| 20110042472 | Portable Catalytic Heater - Provided is a portable heating device comprising a combustion-powered heater, a regulator, and an oxygen depletion sensor. The combustion-powered heater may be supplied by an associated fuel source and may comprise a combustion region comprising a catalytic surface. The regulator may be adapted for fluid communication with the associated fuel source. The oxygen depletion sensor may comprise a burner and a temperature detector. The burner may be in fluid communication with the regulator and may be adapted to combust fuel form the regulator with air to produce a flame. The temperature detector may be adapted to detect the temperature of the flame and may be adapted to selectively render the combustion-powered heater non-functional. | 02-24-2011 |
| 20110045417 | Thermocouple Shutoff for Portable Heater - Provided is an assembly comprising a combustion-powered heater, a target component, and a transducer operatively engaged with said target component. A combustion-powered heater may comprise a combustion site adapted to power said heater. A target component may be engaged with the combustion site. A transducer may be adapted to measure the temperature of the target component and adapted to shut-down said combustion-powered heater in response to a temperature measurement of less than a temperature limit. | 02-24-2011 |
| 20110265779 | Forced Air Heater Including On-Board Source of Electric energy - A heating device may comprise a control assembly having a self-contained, on board power supply. A control unit may control the operation of the heater and the power supply may comprise a first power source in electrical communication with the control unit, wherein the control unit controls the operation of the first power source to selectively supply electrical power to at least a portion of the heating device; and, a second power source in electrical communication with the control unit, wherein the control unit controls the operation of the second power source to selectively supply electrical power to at least a portion of the heating device. | 11-03-2011 |
| 20110268429 | Forced Air Heater Including On-Board Source of Electric Energy - A forced-air heater having a self-contained on-board electric-power supply that allows the forced-air heater to operate without an external electric power source; a fuel tank; a combustion chamber; a support; a housing including upper and lower housing portions; a motorized fan that during operation draws in ambient air through an air intake and forces air into the combustion chamber. | 11-03-2011 |
