Patent number: 9784545Abstract: Solid propellant systems include a main propellant and a secondary propellant in contact with the first propellant that exhibits autoignition temperatures of at least about 100° F. lower than the autoignition temperature of the main propellant. The secondary propellant of the present invention is most advantageously employed with conventional AP-containing solid propellant formulations as the main propellant, especially formulations containing both AP, an energetic solid, and a binder. In especially preferred forms, the secondary propellant will include a nitramine which is at least one selected from nitroguanidine (NQ), cyclotrimethylene trinitramine (RDX) and cyclotetramethylenetetranitramine (HMX), and a binder which is at least one selected from HTPB, HTPE or glycidyl azide polymer (GAP). Most preferably, the secondary propellant will include a combination of nitramines which includes NQ and one of RDX or HMX.Type: GrantFiled: March 3, 2003Date of Patent: October 10, 2017Assignee: AEROJET-GENERAL CORPORATIONInventors: Kenneth J. Graham, Edna M. Grove, Robert D. Lynch, Guy B. Spear

Patent number: 6340401Abstract: An improved thermally stable, storage stable gas generating composition characterized by both an increased burning rate and a decreased pressure exponent for producing a clean, nontoxic, substantially ash- and solids-free gas for inflating inflatable structures such as vehicle airbags is provided. Optimum combustion efficiencies and operating pressures are achieved in the improved gas generating composition by adding an effective amount of a copper or copper compound catalyst to a gas generating composition that is preferably a eutectic mixture or solid solution of ammonium nitrate, at least one highly oxygenated fuel, potassium or cesium perchlorate or nitrate and an optional binder.Type: GrantFiled: February 7, 2000Date of Patent: January 22, 2002Assignee: Atlantic Research CorporationInventors: Brian K. Wheatley, James D. Martin, Robert D. Lynch

Patent number: 6334961Abstract: Solid gas generant compositions produce low particulates (e.g., condensed ash) when ignited. The solid gas generant compositions most preferably include a nitramine, at least one oxidizer selected from nitrates of strontium or cerium, in admixture with or without potassium perchlorate, and a binder. Graphite may optionally be employed. The gas generant compositions are usefully employed in inflatable vehicle occupant passive restraint systems (e.g., air bag systems).Type: GrantFiled: November 9, 1999Date of Patent: January 1, 2002Assignee: Atlantic Research CorporationInventors: Brian K. Wheatley, Norman H. Lundstrom, Robert D. Lynch, R. Stephen Scheffee, James D. Martin

Patent number: 6277296Abstract: Fire suppressant compositions which are substantially free of ammonium nitrate and which comprise potassium nitrate in an amount sufficient to generate at least about 10 wt. % potassium carbonate when combusted. Most preferably, a guanidine salt, such as guanidine nitrate, is used in combination with the potassium nitrate. The compositions employed in the present invention have low pressure exponents, high burning rates and low flame temperatures.Type: GrantFiled: November 30, 1999Date of Patent: August 21, 2001Assignee: Atlantic Research CorporationInventors: Robert S. Scheffee, Jamie B. Neidert, Robert E. Black, III, Robert D. Lynch, James D. Martin

Patent number: 6045726Abstract: A fire suppressant composition is provided which exhibits a low pressure and low flame temperature. The composition comprises ammonium nitrate and a guanidine salt or derivative which produces greater than 3 moles of inert gas per 100 grams of composition and alkali metal or alkaline earth salts for flame suppression. The composition may also include iron or iron oxide.Type: GrantFiled: July 2, 1998Date of Patent: April 4, 2000Assignee: Atlantic Research CorporationInventors: Edna M. Williams, Brian K. Wheatley, Jamie B. Neidert, Robert D. Lynch, James D. Martin

Patent number: 5154413Abstract: An accessing guide in combination with the paper path of a deck for transporting paper documents. The combination includes: a deck for supporting and transporting paper documents seriatim; and an adjustable side guide mounted on the deck for movement perpendicular to the direction of the paper path for guiding the flow of documents along the deck. The guide has a pivotable rail which can pivot away from the paper path in order to allow access to the paper path by an operator.Type: GrantFiled: September 9, 1991Date of Patent: October 13, 1992Assignee: Pitney Bowes Inc.Inventors: Richard D. Boughton, Joan T. Wagner, Kenneth A. Schulz, Robert D. Lynch, Jr., Joseph H. Marzullo
