Patent number: 6095251Abstract: A fire is extinguished and suppressed, by a dual stage fire extinguisher. In a first stage, a sufficient amount of an inerting agent is delivered to extinguish the fire. Once the fire is extinguished, in the second stage, a different amount of inerting agent is delivered to the fire to prevent its re-ignition. Since suppression typically requires less of the inerting agent than extinguishing, a reduction in the weight of the inerting agent is achieved with the dual stage process making the system particularly amenable to aircraft applications such as in an engine nacelle or cargo dry bay.Type: GrantFiled: July 14, 1998Date of Patent: August 1, 2000Assignee: Primex Technologies, Inc.Inventors: Robert M.

Patent number: 5655608Abstract: The present invention relates to a fire fighting equipment, comprising at least one spray head (1) with a number of nozzles (3) directed obliquely sideways. The nozzles (3) are arranged so close to each other that the fog formation areas of the individual nozzles intensify the fog flows and provide a suction to cause the fog formation areas to be compressed into a continuous directional fog spray.Type: GrantFiled: March 14, 1995Date of Patent: August 12, 1997Inventor: Goran Sundholm

Patent number: 5651416Abstract: A scheme for essentially instantaneous kills of fires in crew compartments s shown which is effective over a wide variety of climatic temperatures. An extinguishant is mixed according to the formula, (M.sup.+ A.sup.-).sub.sat +H.sub.2 O+fps+d @T, where A.sup.- is either an acetate in the form H.sub.2 CCOO.sup.-, chloride, or bromide, M.sup.+ is an alkali metal or ammonium, fps is a freezing point suppressant, d is a surfactant, and (M.sup.+ A.sup.-).sub.sat is a saturation level of compound M.sup.+ A.sup.- at temperature T. In one embodiment of our scheme, potassium acetate is both the (M.sup.+ A.sup.-).sub.sat and the fps in the foregoing formula. The scheme includes charging an extinguisher bottle with the extinguishant under pressure, opening a gate device connecting the bottle to a feeder line, and allowing the extinguishant to flow in the line to a nozzle. The extinguishant is then sprayed through the nozzle, which is disposed at the fire in the compartment.Type: GrantFiled: May 16, 1996Date of Patent: July 29, 1997Assignee: The United States of America as represented by the Secretary of the ArmyInventors: Michael J. Clauson, John O. Hughes

Patent number: 5626194Abstract: A Fire Fighting System includes a vehicle with one or more mounted motors, a fire shield system, and an emergency fire retardant discharge system. The motors are equipped with cutting elements including cutting teeth, paddle teeth, and severe duty fire whips. The fire shield system may include a series of flame and heat retardant coverings placed on all exposed parts of the system to prevent damage from exposure to extreme heat. The emergency fire retardant discharge system distributes chemical fire retardant in the event the fire comes too close to the system. In operation, the vehicle operator positions the system at the edge of a fire line and energizes the motors causing the cutting elements and whips to begin rotating. Once rotating at full speed, the vehicle is advanced along the fire line with the cutting elements cutting and slashing the burning vegetation. Once cut, the burning vegetation is thrown aside by the severe-duty fire whips that rotate to throw the debris back towards the fire.Type: GrantFiled: September 20, 1994Date of Patent: May 6, 1997Assignee: FAV, Inc.Inventor: Richard W. White

Patent number: 5613564Abstract: A fire extinguisher apparatus is provided for preventing and extinguishing fires in an engine compartment of a motor vehicle. The apparatus includes a collision sensor assembly supported by the motor vehicle and a fire extinguisher module supported by the motor vehicle. The fire extinguisher module includes a valve assembly. A valve control assembly is electrically connected to the collision sensor assembly, is supported by the fire extinguisher module, and is employed for controlling the valve assembly. A manifold assembly is supported by the motor vehicle and is connected to the valve assembly. The manifold assembly receives a quantity of fire extinguishant from the fire extinguisher module when the valve assembly is operated by the valve control assembly. The manifold assembly includes a first manifold branch which extends along a first side of the engine compartment and includes a second manifold branch which extends along a second side of the engine compartment.Type: GrantFiled: July 31, 1995Date of Patent: March 25, 1997Inventor: Andy J. Rhines

Patent number: 5613562Abstract: There is disclosed an apparatus for suppressing a fire. The apparatus includes a gas generator containing as a propellant, a mixture of a fuel, strontium nitrate as an oxidizer, and magnesium carbonate. When the propellant is ignited, a nitrogen rich effluent is generated that is effective to suppress the fire. By providing the propellant with at least 35%, by weight, of magnesium carbonate, the generation of effluent by-products that are corrosive to aluminum is inhibited.Type: GrantFiled: August 28, 1996Date of Patent: March 25, 1997Assignee: Olin Aerospace CompanyInventors: Lyle D. Galbraith, Gary F. Holland, Donald R. Poole, Robert M. Mitchell
