20090293859 | PORTABLE HEATING APPARATUS AND METAL FUEL COMPOSITE FOR USE WITH SAME - A particulate composite fuel of metal preferably of aluminum for a portable heater. The fuel reacts with oxygen in the air, producing heat. The composite fuel may also be flaked aluminum or iron nanopowder. A portable heater having a fuel mass, at least one thermal conductive member, and at least one insulating member. The heater transfers the heat of the oxidation of the metal particulate fuel to a desired mass to be heated, typically a food item. The multilayered heater also acts as a buffer absorbing released heat and releasing the heat to the desired mass at a rate slower than the absorbing. | 12-03-2009 |

20140127634 | HEATING DEVICES AND METHODS WITH AUTO-SHUTDOWN - A modular heating system and method is presented that automatically shuts down the chemical reaction within a heater if the heat generated by the reaction is excessive. Heaters are designed to generate sufficient heat to warm food or drink in an adjacent container. If the container is empty, or if the heater is dislodged from the container, the heat generated by the heater will become dangerously high. When excessive heat is generated by the reaction in the heater, systems and methods of the present invention respond by terminating the reaction before all of the reaction mixture has reacted. | 05-08-2014 |
