Patent number: 5206456Abstract: A thermal battery activated by external heat comprising an anode, e.g. cosed of a lithium-aluminum alloy, a cathode, e.g. composed of iron disulfide, and an electrolyte, e.g. a lithium chloride-potassium chloride eutectic, the electrolyte being inactive at ambient temperature but being activated by melting at a predetermined temperature when exposed to external heating. The battery can be used as a sensor or to ignite pyrotechnic and power electronic devices, in a system for reducing the hazard of ordnance exposed to detrimental heating. A particular application is the use of the battery to activate a squib to function in conjunction with one or more other components, to vent an ordnance case, preventing its explosion in a fire.Type: GrantFiled: November 5, 1990Date of Patent: April 27, 1993Assignee: The United States of America as represented by the Secretary of the NavyInventors: Louis Pracchia, Ronald F. Vetter, Darwin Rosenlof

Patent number: 4557197Abstract: A pyrogen igniter for small nozzle applications has a high initial output. igh initial output and long duration burning are achieved through utilization of a slow burning igniter main charge in conjunction with a booster pellet. A nozzle plate focuses and directs the output of the igniter as a gas jet while shielding the interior of the igniter from exterior temperature and pressure fluctuations which might otherwise operate to extinguish the igniter. A flush bridgewire/pressed prime igniter configuration and the elimination of loose powder in the igniter facilitates economical production and long shelf-life.Type: GrantFiled: March 30, 1984Date of Patent: December 10, 1985Assignee: The United States of America as represented by the Secretary of the NavyInventors: James O. Smith, Ronald F. Vetter, George F. Sieg

Patent number: 4494373Abstract: In a rocket motor having an insulative coating on selected portions of the xterior casing, one or more ribs are used to structurally strengthen portions of the casing and to reinforce thermal stress patterns which will cause failure venting at a predetermined point of the rocket motor as a cook-off safety feature.Type: GrantFiled: May 17, 1982Date of Patent: January 22, 1985Assignee: The United States of America as represented by the Secretary of the NavyInventors: Ronald F. Vetter, Theodore A. Hicks, Warren R. Compton

Patent number: 4478151Abstract: Positive rocket motor pressure hull venting in the case of deck fires is vided by placement of thermite masses at spaced locations on the interior of the hull. Small cylindrical masses as well as strip formed masses are employed. The thermite mass includes a small amount of structurally formed aluminum as well as the conventional powdered aluminum.Type: GrantFiled: February 28, 1983Date of Patent: October 23, 1984Assignee: The United States of America as represented by the Secretary of the NavyInventors: Ronald F. Vetter, Howard W. Gerrish, Jr., Lawrence F. Lesniak

Patent number: 4458482Abstract: A bare patch in an insulating coating on a cylinder is shaped to reinforce tress patterns to cause failure at a predetermined point as a cook-off safety feature.Type: GrantFiled: May 17, 1982Date of Patent: July 10, 1984Assignee: The United States of America as represented by the Secretary of the NavyInventors: Ronald F. Vetter, Theodore A. Hicks, Warren R. Compton

Patent number: 4458483Abstract: An end flap construction for a rocket motor prevents hot vapors from enteg the motor void and causing motor ignition.Type: GrantFiled: October 21, 1982Date of Patent: July 10, 1984Assignee: United States of America as represented by the Secretary of the NavyInventor: Ronald F. Vetter

Patent number: 4458595Abstract: An improved rocket motor has a first layer of silicone rubber and a second ayer of an ablative lining placed between the rocket motor casing and the propellant grain. The ablative lining layer contains chopped novoloid fibers 14 microns in diameter and nominally 1 mm in length interspersed throughout a polymeric composition.Type: GrantFiled: June 7, 1982Date of Patent: July 10, 1984Assignee: The United States of America as represented by the Secretary of the NavyInventors: Howard W. Gerrish, Jr., Ronald F. Vetter, George F. Sieg, Harold L. Bennett

Patent number: 4442666Abstract: The invention describes a rocket motor having a thermal barrier around a sile casing with gaps along the side to permit initial burning on the outer portion of the grain at rupture of the casing and venting prior to burning over the inner bore to avoid explosion.Type: GrantFiled: October 21, 1982Date of Patent: April 17, 1984Assignee: The United States of America as represented by the Secretary of the NavyInventor: Ronald F. Vetter
