Abstract: A two axis adjustable optical mount capable of lock down after alignment is rovided by a dual ring arrangement which represents a segment of two concentric spheres. An optical element such as a lens or mirror is held within an inner ring by a retaining ring. The inner ring fits within the outer ring to form a partially concentric sphere arrangement across the diameter. Orthogonally mounted set screws can be used to adjust the relationship of the inner ring to the outer ring and a collar screw clamp is used to freeze the relationship between the inner and outer rings once the desired orientation is achieved.

Abstract: A new one-step synthesis of cyclic 1,3 dinitramines is disclosed. This syesis utilizes a solution of N.sub.2 O.sub.5 in 100% nitric acid as the nitrolyzing media. The polynitramines thus produced find utility as explosive and propellant ingredients, gas generants and in other ordnance applications.

Abstract: A new polynitro compound pentanitrophenyl azide is disclosed, and a method of preparation is disclosed wherein hexanitrobenzene is reacted with sodium azide. This new polynitro compound is useful as an explosive.

Abstract: Optical devices which reduce the risk of damage by high energy laser pulses re made by applying particles to the surface of optical components. The particles serve as plasma initiation sites. The particles are made of material capable of producing large numbers of free electrons when illuminated above a preselected power level. Above the preselected power level, transmittance or reflectance of the optical component is limited by the plasma created by the free electrons.

Abstract: The preparation of transition metal dithiene complexes is disclosed. By the process improved yields of the metal dithiene complexes are realized by substituting highly polar aprotic solvents such as N-methylpyrrolidinone or high boiling point solvents such as diethylene glycol in place of dioxane in the reaction sequence.

Abstract: A system which processes analog signals from millimeter wave sensing system nto digital words in an organized manner which are then stored into a data memory representing the pixels in the wave images. The pixels are read out at a rate and format to a standard television monitor thus providing a real time display of the sensed image.

Abstract: A controlled opening shock parachute is made by dividing each gore of a cular parachute into two panels, an upper and a lower. The adjoining edges of the panels are of different lengths and left unjoined so an uneven slit is formed. During the parachute's opening sequence, air flows into the slits to open the upper panels. After the upper panels are inflated, air flows out of the slits as the lower panels open.

Abstract: A remote reservoir for automatically dispersing a liquid electrolyte mixt into the cells of a battery upon activation.

Abstract: A microcomputer controlled electronic fuze capable of surviving a hard tat impact is disclosed comprising two epoxy potted printed circuit boards mounted back to back of which one of the boards is designed to survive impact and contains the microcomputer controller, storage charge, timing circuit, and fire pulse detonator circuit. The other board carries an electric motor drive circuit for mechanical timing and detonator alignment, a detonation delay command storage circuit, and an AC rectifier and voltage regulator circuit coupling a wind turbine generator power supply to the fuze.

Abstract: A bus adaptor is a circuit which interconnects incompatible digital systems hat are asynchronous to each other, through alteration of bit order arrangement and composition, time frame, speed and shape of signals which involve data signals being superimposed with a clock signal and smoothed and vice versa. The adaptor circuit handles intersystem signals that enter and leave via separate parallel paths of one system and enter and leave via a single bidirectional path of another system.

Abstract: The use of high vinyl-containing vinylmethylsiloxane polymers as high temature insulating materials.

Abstract: A pyrotechnically actuated dual air valve is hermetically sealed on both et and both outlet ports of static and dynamic air ducts until the dual air valve is actuated by a squib charge. A single piston, when activated by the squib charge, concomitantly opens all four hermetic seals to allow separate static and dynamic air flows through the dual air valve.

Abstract: Apparatus for predicting the cookoff characteristics of a confined explosive includes a cylindrical housing retained between an instrumentation plate and a witness plate. Small explosive samples contained in sample tubes are inserted within a heat conductive sleeve which is further disposed within the cylindrical housing. Electrical ring heaters are a source of heat the application of which eventually causes the confined explosive to react. Temperature measurements within the housing are obtained utilizing a thermocouple assembly which is inserted through the instrumentation plate and into a groove in the heat conductive sleeve. The degree of damage to the apparatus occasioned by the reaction of the heated explosive predicts the reaction of a full scale ordnance item containing that explosive to exposure to a fire.

Abstract: An improved fin attachment having a socket for reception of a tang mounted n a missile fin, an element for drawing the tang into the socket, and frusto-conical concentric rings which engage the tang and the socket to connect them rigidly in a predetermined angular relation. All elements of the attachment are retained so as not to be lost when the fin is detached, and the attachment provides effective connection without the use of complex shapes or precise manufacturing tolerances.

Abstract: A stripline printed circuit power divider is disclosed disposed on opposite ides of a central dielectric substrate in a three substrate layered stripline orientation. An electrically coupled, coplanar, dual lead of the power divider disposed on opposite sides of the central dielectric substrate is joined into a single lead on one side of the substrate by diverting each coplanar lead and passing one lead through a hole in the dielectric to be joined with the other lead on a single surface of the dielectric.

Abstract: A fluid oscillator having a tube provided with a slit which is pivotable o a boundary layer of air flowing over a missile for arming and is pivotable from the missile exterior. The tube is configured so that the boundary layer excites oscillations within the tube at a predetermined velocity at which the missile is to arm.

Abstract: The real-time polar controlled video processor electronically rotates scene nformation in a real-time video processor. By dynamically specifying the origin of each desired consecutive output line from subpixel space, and by specifying the delta "X" and delta "Y" inputs (of X-Y Cartesian coordinates) to a real-time coefficient generator, a subpixel generator can sweep through a stored image database at any arbitrary angle and scale factor. Subpixels which are generated sequentially describe any image size, orientation, and position. This scheme allows dynamic line-by-line accommodation of dynamically rotating sensor outputs.
