| 20080213715 | High efficiency radiant burner - A naturally aspirated, fully aerated radiant burner and optional heat exchanger arrangement where the radiant burner has a generally enclosed cavity defined, at least in part, by fuel gas impermeable surroundings and a lower surface of fuel gas permeable burner element, wherein cavity preferably has two opening exposed to an oxidizer source. Sealingly coupled to openings are mix tubes, each having respective first ends and second ends, wherein first ends occupy openings and second ends extend into and are exposed to cavity. Fuel gas injectors, which during use are in fluid communication with fuel gas, are positioned to introduce fuel gas into mix tubes and entrain only slightly more air than needed for stoichiometric combustion. Pre-combustion gasses migrate to upper surface where stable stoichiometric combustion occurs, resulting in low CO and NOx emissions, increased wind resistance and elevated combustion gas temperatures Connecting the heat exchanger directly to the burner further increases its wind resistance and prevents dilution of the combustion gases by wind or free convection. | 09-04-2008 |

| 20140057220 | LIGHTER ASSEMBLY - A portable, handheld lighter assembly for lighting a lighting end of a rolled tobacco product, such as a cigarette or a cigar, includes an elongated body formed with opposed first and second channels formed on either side of a combustion zone and a stop formed in the elongated body. The combustion zone traverses the stop so as to couple the first channel in gaseous communication with the second channel. The stop restricts movement of a rolled tobacco product into the second channel from the first channel and restricts movement of a rolled tobacco product into the first channel from the second channel. A lighter is coupled to the elongated body and is for applying lighting heat to the combustion zone at the stop for lighting a lighting end of a rolled tobacco product applied against the stop in the combustion zone from the first channel or the second channel. | 02-27-2014 |
| 20150292738 | Valve Assembly For A Gas Lighter - A gas lighter valve assembly that can be fitted easily and tightly into a gas lighter body or a well as a free-floating entity not fixed to the gas lighter body or well. The valve assemblies integration as a free floating entity within the lighter body or well avoids the necessity of an interference fit. To avoid the necessity of an interference fit, valve assembly positioning and stability is achieved by the use of an o-ring which is compressed by downward force exerted by a pressing cover upon a bushing or directly upon the o-ring. By eliminating the stress and friction typically caused by an interference fit, the lighter body and reservoir can be made from a variety of materials including non-crystalline resins. | 10-15-2015 |
