20090031931 | ADJUSTABLE TEMPORARY CASKET - A temporary casket made substantially from burnable material, having a positionable inclining mechanism inside a casket shell. The temporary casket may be inserted into a formal, traditional casket where the temporary casket shell protects the traditional casket. Inside the temporary casket, a plank is attached by a clamp or bracket to an adjusting mechanism for adjusting the tilt angle between the plank and the floor of the casket shell. The mechanism also includes a vertical threaded rod that engages the clamp, allowing the rod to be rotatable and move the clamp axially along the rod to lift or lower the plank. This allows a funeral director to easily adjust the deceased to achieve the most “restful” state, and without jostling or appearing disrespectful to the deceased. After a service, the deceased, along with the temporary casket and the mechanism itself, may be cremated. | 02-05-2009 |
20090031932 | Method for Handling Substance from which Combustible Gas Volatilizes, Method for Producing Solid Fuel, Method for Storing Solid Fuel, Method for Using Solid Fuel, and Apparatus for Using Solid Fuel - A method for handling a substance from which a combustible gas volatilizes. A method for handling a substance from which a combustible gas volatilizes, in which, when such substance is handled inside an apparatus with a high degree of hermeticity, air is introduced into the apparatus and the substance is handled in a state in which the volatilized combustible gas is diluted to a concentration at which neither explosion nor fire occurs. With this method for handling a substance from which a combustible gas volatilizes, the combustible gas is diluted with air to a concentration at which neither explosion nor fire occurs, without using inactive gases such as nitrogen or carbon dioxide that have to be produced or purchased. Therefore, a substance from which a combustible gas volatilizes can be inexpensively and safely handled in operations such as mixing and storing. | 02-05-2009 |

20110041740 | RECUPERATIVE COMBUSTION SYSTEM - The methods and systems described herein relate to a recuperative combustion system that recuperates energy from fuel combustion that would otherwise be lost. The recuperative combustion system minimizes or eliminates the need for an air separator unit through the use of a clean water splitter section, consisting of a thermochemical cycle or high-temperature electrolysis.

The oxygen produced by the water splitter provides oxygen necessary for oxy-fuel combustion, thereby reducing or eliminating the need for the power intensive air separator unit and/or external oxygen source, significantly increasing the efficiency of the oxy-fuel combustion cycle. Hydrogen produced by the water splitter may be used for a variety of industrial uses, or combined with carbon dioxide (captured from the flue gases produced by said combustion process) to produce methanol. Methanol can further be refined in a methanol to gasoline reactor to produce dimethyl ether, olefins or high grade gasoline. Described herein are methods and systems that 1) increase oxy-fuel combustion efficiency, 2) produce hydrogen for a suite of industrial/energy uses, and 3) capture carbon dioxide and convert it to high value hydrocarbons. | 02-24-2011 |
