Patent number: 10378870Abstract: A meltable fuze plug for a munition has an upper flange ringed by a specially corrugated steel washer to absorb impacts of various strength levels from various directions, and against falls, to protect the ogive and munition. The meltable fuze plug renders the munition insensitive. It is formed of a meltable plastic for facilitating venting of the munition's interior areas during unexpected fires or explosions.Type: GrantFiled: May 30, 2018Date of Patent: August 13, 2019Assignee: The United States of America as Represented by the Secretary of the ArmyInventors: Thomas Wu, Shana Groeschler, Keith Fulton, Leon Moy

Patent number: 6964248Abstract: A gas-fired water heater is provided with a combustion shutoff system which precludes further combustion within the water heater's combustion chamber in response to a combustion temperature therein reaching a predetermined level correlated to and indicative of a predetermined, undesirably high concentration of carbon monoxide present in the combustion chamber. In various illustrated embodiments thereof, the combustion shutoff system is operative to terminate further combustion air inflow to the combustion chamber, or terminate further fuel flow to the burner portion of the water heater.Type: GrantFiled: September 28, 2004Date of Patent: November 15, 2005Assignee: The Water Heater Industry Joint Research and Development ConsortiumInventors: Gordon W. Stretch, Bruce A. Hotton, John H. Scanlon, Gary A. Elder, James T. Campbell, Larry D. Kidd, Eric M. Lannes, Garrett Doss, Michael W. Gordon, James M. Martin, James W. Mears, Thomas E. Archibald

Patent number: 6814031Abstract: A gas-fired water heater has a combustion chamber with a bottom wall defined by a perforated flame arrestor plate forming a portion of a flow path through which combustion air may be supplied to a burner structure within the combustion chamber. During firing of the water heater a combustion air shutoff system having a heat-frangible temperature sensing structure disposed within the combustion chamber senses an undesirable temperature increase in the combustion chamber, caused by for example a partial blockage of the flow path, and responsively terminates further air flow into the combustion chamber, thereby shutting down the burner, prior to the creation in the combustion chamber of a predetermined elevated concentration of carbon monoxide.Type: GrantFiled: October 9, 2003Date of Patent: November 9, 2004Assignee: The Water Heater Industry Joint Research and Development ConsortiumInventors: Gordon W. Stretch, Bruce A. Hotton, John H. Scanlon, Gary A. Elder, James T. Campbell, Larry D. Kidd, Eric M. Lannes, James M. Martin, James W. Mears, Thomas E. Archibald

Patent number: 6543393Abstract: A fire suppressing water heater system is provided including a fire suppressing water heater system is provided including a water heater, fire detection means, spray means, and water transport means. The water heater will preferably include a cold water intake and a hot water return. The spray means are designed to activate when a fire is present in the proximity of the water heater so as to quickly extinguish the fire. Fire detecting means may be configured to activate the spray means when evidence of a fire, such as heat or smoke, for example, is detected. Furthermore, in the event of a fire, water transport means direct a quantity of water from the cold water intake of the water heater to the spray means.Type: GrantFiled: March 29, 2002Date of Patent: April 8, 2003Inventor: Kenneth G. Cunningham
