Abstract: An evacuating-charging valve assembly consisting of a valve permanently mtable onto a fluid system such as an air conditioning system and a connecting head temporarily attachable to the valve. Two embodiments are shown, in both of which the valve has a flange portion for mounting to the fluid system, and a boss portion. Each boss portion is internally bored and threaded and has a ball-ended setscrew, with the ball against the end of a hole through the flange. In one embodiment, the setscrew has slots through its threads, and the connecting head screws into the boss. In the other embodiment, holes are bored through the boss and the connected head screws onto external threads on the boss. Both connecting heads have a setscrew wrench inside, and an external knob for rotating or linearly moving the wrench, and have passageways through them to an external hose connection. When the setscrews are unscrewed, a fluid passageway exists between the hole through the flange and the external hose connection.

Abstract: Gun muzzle deflection detector means comprising a depletion mode linear photodiode sensor having four electric outputs representing elevational and azimuth displacement of an optical signal impinging on the sensor face, said sensor outputs being combined and amplified to provide error signals representative of the muzzle deflection from a true zero deflection condition in the elevation and azimuth directions. An automatic gain control is used to adjust the error signals up or down inversely according to the absolute values of the light impinging on the sensor, thereby compensating for possible errors due to fog or airborne particulates in the optical system.

Abstract: Apparatus and method of anti-armor missile trajectory shaping for optimum rhead penetration of armor by a guided missile. The guidance system utilizes a terminal homing guidance unit in conjunction with a programmed control signal through the missile's autopilot to cause the missile to cruise at low altitudes and then dive onto the armor target. The terminal dive angle can be selected dependent upon the target's armor characteristics.

Abstract: The invention relates to a hermetically sealed ballistic projectile having nose, material containing shell and a piston. The nose has a rearwardly increased diameter and a rearward region of decreased diameter, the shell has a forward most region of mating diameter with the rearward region of the nose and is in fixed but frangible contact with the nose. The piston is in hermetic sealed engagement with the inner surface of the forward region of the shell with its forward surface proximate the rearward surface of the nose. Material is used to fill the interior space of the shell between the piston and the rearward inner surface of the shell. The materials can be of a liquid, semi-liquid, slurry or solid consistency and are explosive, hypergolic, incendiary or otherwise reactive or inert, and contained in a single or a plurality of separate component containing compartments.

Abstract: A novel fluid-flow control damper is disclosed. The damper comprises a freely pivotable closure situated in a fluid-flow conduit, such as an air duct. The closure is maintained in a closed position by a simple latching means, and may be maintained in an open condition by means of fluid flow through the conduit. Several of these dampers may be used in combination with a single fluid temperature control device, resulting in a simple, low-cost multizone heating or cooling system.

Abstract: A primer device has a coupling device for efficiently dispersing the ignin products from a primary propellant into a main charge. The coupling device has a housing with a central chamber. This chamber has an inlet and outlet port. The housing and its inlet port are sealed over a cavity containing a primary propellant. A valve device is mounted at the inlet port for initially sealing combustion gasses from the primary propellant within the cavity. This initial interval during which the cavity is sealed, fosters thorough burning of the primary propellant. When combustion causes pressure sufficient to open the valve device, combustion products enter the central chamber of the housing. These combustion products bear upon a frangible seal, which is mounted at the outlet port of the housing. The frangible seal ruptures at a predetermined and repeatable pressure.

Abstract: Longitudinal stresses in the explosive grain of a rapidly accelerated high xplosive projectile are absorbed in longitudinal reinforcement members and are transferred therefrom to the casing of the projectile. Transmission of the acceleration load from the grain to the longitudinal reinforcement members may be by friction, adhesive bonding or by area mismatch. A stress decoupling layer in the aft end of the projectile may be employed for matrix stress decoupling.

Abstract: Smooth layers of a metal are produced on a glass substrate where a large ferential expansion coefficient of the metal relative to the substrate produces very large stresses in the metal when the metallized substrate is subjected to a post deposition anneal. The method involves depositing a layer of a metal having a very small self diffusion coefficient at the anneal temperature prior to depositing the metal having the large differential expansion coefficient.

Abstract: A millimeter wave line scanner is disclosed providing steered fan-shaped ms from opposite faces at substantially equal angles of a semiconductor waveguide, rectangular in cross section, and having a plurality of equally spaced metallic perturbations or strips disposed on one of the two radiating sides or faces. Different angles of scan are selectively obtained by means of at least one distributed longitudinal PIN diode formed on an adjoining side of the semiconductor waveguide having electrical circuit means coupled thereto for controlling the diode's conductivity which acts to change the guide wavelength and accordingly cause a variation in radiation angle of the two equal beams radiating from opposite faces. The waveguide with one or more PIN diodes may also be used as a phase shifter. To reduce losses, a dielectric insulating layer is disposed between each PIN diode and the waveguide, which prevents the propagation of the wave into the PIN diode.

Abstract: A safe electroexplosive device such as an electric match is provided by cring the existing electric match with a coating that prevents electrostatic discharge penetration of the coating. The coating may be either an inner insulator with a conductive outer layer or it may be just a conductive layer over the match. Use of the insulator coating allows an open-circuit terminal to remain once the device is initiated by its power source. Use of only the conductive coat requires the coat to have a resistance greater than the match bridgewire circuit resistance and leaves a low resistance path across the power source after the device has been fired.

Abstract: An annular combustor for a jet turbine engine of generally rectangular cr-section having an axially-projecting aft exhaust outlet is lined by a plurality of circumferentially-extending heat-insulating liner segments, preferably ceramic, spaced from the metal shell of the combustor by spring-like spacers. The liner segments have offset tabs at their edges to slidably mate with each other and with retaining clips adjacent to the exhaust outlet, thereby being slidably secured to accept expansion of the metal shell without placing appreciable stress on the liner segments. Arcuate, generally planer liner segments along the forward and aft walls of the combustor are keyed in place by a radially-inward flanged liner segment along the outer perimetrical wall of the shell.

Abstract: A wide angle light intensity pickoff system, having a very fine signal reution of less than a degree, provides a linear range of about .+-.35 degrees with a total range of .+-.90 degrees. The pickoff system can be used with any angular measurement system. In a gyro system all of the active circuit components, an offset optical source and a detector, are mounted on the unstabilized housing structure. Only a fiber optic bundle is required on the stabilized gimbal for coupling optical signals to the detector. There is no mechanical contact between the stabilized gimbal and the unstabilized housing structure. This prevents gimbal/housing coupling torques while providing a wide angle pickoff capability.

Abstract: A missile control and guidance system employing a combination of generally ertically disposed ailerons and generally horizontally disposed elevators. In order to make a horizontal turn, a combination of aileron and elevator deflections is used, to cause the missile to make a "blanked" turn. The ailerons and elevators are controlled by servos activated by a logic circuit. The logic circuit is connected to a segmented target detector. The missile will maneuver depending on which of the segments of the detector "sees" a target.

Abstract: A triggering device and method for producing nuclear fusion reactions and having two or more intense pulses of high energy electrons derived from a single source and delivered to a target along separate paths but arriving at substantially the same time. The electron beams are produced in the electrode space of an electron accelerator which utilizes a cathode for producing multiple electron beams. Each electron beam is injected into a separate conventional linear pinch discharge. The high energy electron beams follow the pinch discharge and are delivered to the target. The pinch discharge tubes are curved so that each electron beam approaches the target from a different direction for irradiating the target symmetrically. Return conductors strategically located on the outer surface of each pinch discharge tube maintains the curved discharge within the center of the tube and sustains the pinch.

Abstract: Disclosed is an all amine borane gas generating system which consists of razine bis-borane or its deuterated derivative in the form of a compacted solid propellant pellet which serves as the thermal stimulus for the decomposition of itself. An all amine borane gas generating system which additionally consists of diborane diammoniate or its deuterated derivative provides a higher yield of hydrogen or deuterium with a higher purity from a self-sustaining reaction after the self-sustaining reaction is initiated by a heat source (e.g., an electrically heated nichrome wire) sufficient to initiate the reaction. This all amine borane gas generating system which consists of N.sub.2 H.sub.4.2BH.sub.3 and H.sub.2 B(NH.sub.3).sub.2 BH.sub.4 is in the form of a compacted solid propellant pellet. The pellets are formed to the desired configuration employing pressures from about 500 to about 10,000 pounds total load. The solid propellant pellets are useful as a H.sub.2 or D.sub.2 generation sources for fuels for lasers.

Abstract: Disc shaped quartz crystal resonators of plano-convex, plano-plano, and bnvex configurations have the b-mode resistance raised relative to the c-mode resistance by the proper choice of mounting geometry, thus suppressing the undesired b-mode in precision oscillator circuits without the use of added circuitry.
