Abstract: An air-reactive chemiluminescent formulation is encapsulated and material ich will catalyze the reaction of the formulation with air is affixed to the outside of the capsule. When the capsule is crushed, the formulation, air and the catalyst all come into contact with one other and high intensity light is produced rapidly.

Abstract: A self-sealing fuel tank which utilizes elongated nonself-adhering polymer ibers attached to the inner surface of the tank wall and interwoven to form a carpet-like liner for efficiently sealing large tears and cored holes. After penetration of the tank wall by a large or tumbling projectile, escaping fluid causes nearby elongated fibers to be swept into the hole, thereby choking the escaping fluid flow. Conventional small caliber self-sealant incorporated in the tank wall then flows into the hole choked by fibers and completes the seal.

Abstract: Calcium formate is heated to a temperature in the range of from 300.degree. to 400.degree. C to form calcium carbonate, hydrogen and carbon monoxide and the gases are bled off. The calcium carbonate is then heated to about 825.degree. C whereby calcium oxide and carbon dioxide are formed and the gas is again bled off. The calcium oxide is then reacted with water to form calcium hydroxide and the calcium hydroxide is reacted with carbon monoxide to regenerate calcium formate and start the process over again. The process provides a convenient method for obtaining a mixture of hydrogen and carbon monoxide gases which are useful for many purposes. The carbon monoxide may be removed from the mixture of gases produced to obtain hydrogen which also finds many uses. Further, a mixture of hydrogen and carbon monoxide suitable for use in the Fischer-Tropsch reaction may be readily produced.

Abstract: A wide angle seeker for missile guidance systems and the like which utili a dual motion mirror in an optical transfer system to allow a missile sensor to be mounted in a stationary position in the missile body remote from the seeker.

Abstract: A fuel consisting essentially of about 80 weight percent hydrogenated nornadiene dimer and about 20 weight percent of a butylbenzene has a balance among volumetric heat of combustion, viscosity and flash point such that the fuel is suitable for use in the Modern Ramjet Engine.

Abstract: A mechanism for transforming heat energy into mechanical energy capable of tilizing heat from low temperature sources such as solar heated water, geothermal hot water and rejected heat from conventional engines. The mechanism uses a series of elements manufactured from a nickel-titanium alloy. These elements are formed into a particular shape called the memory shape and, when mechanically deformed, may be instantly returned to the memory shape by the application of heat.

Abstract: Geothermal energy is used to provide the temperatures and pressure necessary for catalytic conversion of carbon monoxide and hydrogen to methanol by lowering the reaction chamber into a geothermal well or by otherwise using geothermal fluids to supply heat and pressure to the reaction chamber.

Abstract: An ordnance item casing construction which enables case venting and contred combustion of high energy fuel contained within the casing when the ordnance item is exposed to a high temperature environment. This casing construction utilizes a perforated thermally insulating composite doubler and series of thermally conductive plugs aligned with cavities in the casing wall, and applied to the exterior of the ordnance item. Heat from the high temperature environment is conducted by the plugs to the casing wall.Local ignition and combustion of high energy fuel within the casing rapidly burns through the wall at regions of reduced wall thickness caused by presence of the cavities. The interior of the casing is thereby vented, and catastrophic pressure buildup within the casing is prevented.

Abstract: A fluid polymeric ablator liner is cast onto the inner surface of a ramjet ombustion chamber which has been prepared with a screen liner substrate. A split mold is inserted through the nozzle and assembled inside the chamber allowing a thin layer of ablator to be cast and cured on the dome and nozzle regions of the combustion chamber.

Abstract: A low altitude optical range finder for measuring the range from an aircr or other vehicle to the sea, ground terrain or other object. A source of narrow beam ultraviolet light is attached at one point on the vehicle and illuminates the object. An electromagnetically deflecting image intensifier and photodiode array combination is attached to another point of the vehicle (remote from the first point) for measuring the angle of arrival of the reflected ultraviolet light and, thereby, the range to the object.

Abstract: Methods for preparing ##STR1## wherein n is 3 or 4 and R is H, CH.sub.3 or C.sub.2 H.sub.5. The methods involve forming ##STR2## by reacting p-terphenyl or quaterphenyl with acetic acid and fuming nitric acid, forming ##STR3## by refluxing the dinitro derivative with stannous chloride, hydorchloric acid and acetic acid and forming the dialkylamino derivative by refluxing the diamino derivatives with a suitable trialkyl phosphate. Also, ##STR4## derivatives may be prepared by refluxing the diamino derivatives with sodium nitrite and hydrochloric acid to form ##STR5## AND REACTING THIS INTERMEDIATE WITH A MIXTURE OF ACETIC ACID AND EITHER WATER OR ALCOHOL. The compounds are useful as lasing dyes.

Abstract: The warhead of a missile is loaded with a payload that can either be burned r exploded. If propulsion is lost and either aerodynamic steering is not present or the velocity level of the missile is degraded to a point where steering is marginal, steerage is maintained by igniting the warhead payload and exhausting gases through nozzles attached to the warhead.

Abstract: A method for manufacturing large, nonplanar, transparent, gelatin-coated ymer sheets is disclosed. These sheets when sensitized, exposed, and developed can record and display holograms. A poly(methyl methacrylate) sheet is coated with nitrocellulose, the nitrocellulose is denitrated, and a gelatin solution is applied, then hardened. The sheet with its gelatin film is then thermally formed to any desired three-dimensional configuration.

Abstract: Cylindrical canister for producing a frusto-conical aerosol explosive clo having a frangible upper wall portion which fails first, producing a generally pancake shaped cloud, and a thickened control ring surrounding its lower wall portion which fails last, producing an upward and outward component to the pancake cloud.

Abstract: A sodium chloride or potassium chloride laser window is rendered anti-reftive by depositing, in order, an As.sub.2 Se.sub.3 layer, a NaF layer and an As.sub.2 Se.sub.3 layer. Near optimum thicknesses to permit transmission of light having wavelengths in the range of from 1 to 12 micrometers are disclosed.

Abstract: A dome for protecting energy responsive instrumentation in a missile is disclosed which utilizes a plurality of wedge shaped transparent elements mounted in a polymer matrix. The transparent elements are arranged so that aerodynamic pressure acting on the dome compresses each transparent element and prevents dome implosion. Individual elements may crack under excessive aerodynamic load, but are held in place by adjacent elements and by aerodynamic pressure, and retain their optical transmissivity during final trajectory to the target.

Abstract: A wide angle radiant energy detection apparatus arranged as a catadioptric assegrainian telescope having a plane secondary mirror is disclosed which utilizes a correcting lens as a structural support for the secondary mirror to reduce losses caused by mirror support structure vignetting. Angular resolution at wide field angles is increased by lenses which reduce oblique spherical aberation, spherical aberation, and coma, and by the more uniform energy distribution across the image field caused by the lack of vignetting optical support structure.
