Abstract: An antenna mounted within a missile launch tube which acts as a communican link between the launcher and the missile. The launch tube is made of fiberglass with a metallic conductor embedded therein to provide radio frequency radiation. The antenna is in the form of a helical conductor and provides radiation in the tube's axial direction.

Abstract: An automatic balancing concept including two annular containers used to dmically balance a rocket during flight. The containers are partially filled with a high density fluid and are installed forward and aft of the longitudinal CG of the rocket. When spin is induced in the rocket the radial CG will shift to the spin axis and the fluid will couple itself to the outside diameter of the ring.

Abstract: An expandable-retractable fan mesh disrupter for camouflaging the shape of he item it is attached to. The disrupter is fabricated of materials and attachments to facilitate rapid emplacement and displacement. In their emplaced expanded condition they confuse potential air and ground observers as to the identity of the objects.

Abstract: A fast, large aperture, electrically actuated shutter mechanism capable of ithstanding high power densities. The shutter's ability to withstand high power densities is achieved by making the shutter plate highly reflective on one side and providing cooling means on the opposite side.

Abstract: A viscometer for use in making viscosity measurements under operating conditions. The viscometer includes a large turbine and a small turbine both operated by the in-line fluid flow. By operating the two turbines simultaneously a comparison of their output frequencies can be made to indicate the ratio point and the viscosity of the fluid flowing is determined from the ratio point.

Abstract: A control system for supplying uncured propellant into the combustion char of a missile. The system includes a moving injector cooperating with a pressurized putty-like uncured propellant. This combination provides the missile with a propulsion system having rapid wide range throttling, shut off and restart capabilities.

Abstract: A system by which in situ observations of optical damage induced in optical omponents by intense thermal radiation may be made. The process includes the determination of the spectral transmission wherein a scanning monochromator is used to illuminate the sample elements with a light beam of monotonically changing wavelength, and the transmitted light is detected and its intensity recorded as a function of wavelength. Optical damage is detected by the resultant changes in the spectral transmission curve.

Abstract: An optical isolator for use in a laser system to protect the system from ue absorption of unwanted scattered light energy. The isolator employs the use of a Faraday rotator combined with the application of an external magnetic field to split absorption lines into two components. By adjusting the magnetic field strength light of a certain frequency passes through the rotator at a spectral position between the split absorption line components. Thus absorption is greatly reduced and the plane of polarization will be rotated without introducing ellipticity into the beam polarization.

Abstract: A centrifugal switch employing the fluent and electrical conducting properties of mercury to open or close an electrical circuit. The mercury is confined within an enclosed chamber and is used as an electrical conducting connector between spaced contact members. Rotating and nonrotating conditions of the switch are relied upon for electrical conduction through the mercury for switch operation.

Abstract: A blast simulator for use as a noise environment tester in a simulated mile launcher. The blast simulator includes a cylinder capped at both ends by a paper disc and encloses a pyrotechnic charge. An electric squib is inserted through either the cylinder walls or the end discs and when actuated ignites the pyrotechnic charge.

Abstract: A mechanical latching mechanism for releasably securing a missile from moent prior to launching. The mechanism includes a control rod for actuating a laterally movable slide bar. Withdrawal of the bar allows the restraint pin to pivot forwardly and downwardly upon movement of the missile, thus withdrawing the tip of the pin from the missile.

Abstract: A spin nozzle system for imparting a thrust to pre-spin a missile prior to aunching. This system includes locating the spin nozzles within the outside diameter of the main missile motor. Also the nozzle exhaust gases are exited into the main motor exhaust cone to thereby augment the total missile thrust.

Abstract: A means for retaining radar elements in a structural configuration for a sed array. The elements are inserted in connectors and are held between two cap plates. The array face and retention configuration is to satisfy electrical and mechanical requirements in order to minimize surface-wave propagation and to predict scanning performance.

Abstract: A coeloscope beam expansion and direction system for high energy lasers wein the system utilizes a cassegrain telescope folded into a coelostat. The beam expander optics are placed between the azimuth axis gimbal and the elevation axis gimbal rather than at the output of the optical train as in the telescope concept or at the input of the optical train as in the coelostat concept.

Abstract: A man-portable anti-tank rocket launcher having rocket storage capability well as being of minimum weight. The launcher includes a tube for launching the rocket and is provided with end closures for protecting the rocket until launching. The tube has provisions for storing the launcher firing sights until rocket firing thus protecting the sights in transportation and storage until use.

Abstract: A fluidic accelerometer employing a transverse-impact modulator for measug acceleration or velocity of a body along a specified axis of the accelerometer. This device uses two similar collinear power-input tubes directed toward each other. The axially opposing power jets from the tubes impact where the flow meets an air-bearing supported proofmass containing annular rings and produce symmetrical radial flow cones at the balance point. A change in the position of the proofmass causes the balance point to move which causes the radial flow cones to become asymmetrical and a net pressure difference is developed in the output receivers.

Abstract: A coupler capable of correctly coupling a microwave source into a resonant avity in a cryogenic environment. The coupler utilizes a rotary mechanical means to adjust the energy through the waveguide-beyond-cutoff into the cavity and control the reflections thereby.

Abstract: A fluidic accelerometer employing a direct-impact modulator for measuring celeration or velocity of a body along a specified axis of the accelerometer. This device uses two similar collinear power-input tubes directed toward each other. The axially opposing power jets from the tubes impact where the flow meets an air-bearing supported proofmass containing annular rings and produce symmetrical radial flow cones at the balance point. A change in the position of the proofmass causes the balance point to move which causes the radial flow cones to become asymmetrical and a net pressure difference is developed in the output receivers.

Abstract: A mini charged round utilizing a low speed, fin stabilized structure with a arhead having a shaped charge for destroying incoming motar, rocket and artillery rounds. The charged round is provided with a delay ignitor which insures detonation of the main primer in the event of missing the target.

Abstract: A mechanism for the protection of optical glass plates against high energy laser radiation effects. The mechanism includes a water coated or water impregnated film positioned in a manner to shield the optical plates and absorb radiation from an attacking high energy laser source. An automatic means is provided for advancing the film when it experiences a rapid rise in temperature.
