Abstract: An electrostatic high potential device which utilizes the generation of etrostatic charges on moving oil to produce a high potential difference on the order of thousands of volts. A metal encased ionizing device or charge generator with a system of passageways of dielectric material has an oil moving therethrough and against the dielectric material to cause a transfer of electric charges between the oil and passageway surfaces. The passageways act as baffles and provide a large amount of surface contact between the oil and dielectric material. The conductive housing of the ionizing device is grounded to draw off the charges on the dielectric material, and a pump circulates the charged oil from the ionizing device to a charge storage device of similar design. Electrodes in the charge storage device draw off the charges on the oil.

Abstract: A corner fed electric microstrip dipole antenna consisting of a thin eleccally conducting, preferably rectangular or square shaped radiating element formed on one surface of a dielectric substrate, the ground plane being on the opposite surface. The feed point is located at one corner of the antenna element and the input impedance is matched with a matching microstrip transmission feed line connected to the corner of the antenna. The length of the element determines the resonant frequency along the Y axis and the width determines the resonant frequency along the Z axis. This antenna is capable of generating circular polarized radiation using a single element and single feed point.

Abstract: An ignition device for igniting a rocket motor comprising a striker adapted or displacement by pressure generated by an auxiliary charge, a percussion-operated priming device for impact by the striker, and an ignition charge for ignition by the priming device and for igniting the rocket motor. The striker, in its inoperative position, is mechanically keyed within a hollow container body having an axial bore therethrough by a pair of diametrically opposed circumferential grooves within which an O-ring is retained. For operation, a fluid generates pressure on the striker, thereby dislodging it from its mechanical keying and driving it to impact the percussion-operated priming device.

Abstract: An asymmetrically fed magnetic microstrip dipole antenna consisting of a n electrically conducting, rectangular-shaped radiating element formed on one surface of a dielectric substrate, the ground plane being on the opposite surface with the radiating element shorted to the ground plane. The length of the element determines the resonant frequency. The feed point is located along the centerline of the antenna length and the input impedance can be varied by moving the feed point along the centerline from the center point to the end of the antenna without affecting the radiation pattern. The antenna bandwidth increases with the width of the element and spacing between the element and ground plane. The element is shorted through the dielectric to the ground plane with rivets or plated-through holes at one end of the element length.

Abstract: An oceanographic sensor which allows in-situ bio-fouling prevention and/or leaning of foreign matter from its surface while simultaneously operating in a sensor mode. The sensor mode is fabricated from crystal substance and utilizes the piezoelectric electric effect. Sensing elements are fabricated on either the outside or inside, or both sides, of the core depending upon what measurements need to be taken. When the sensor is submerged and excited by an electrical potential, at or near resonance, the sensor core will vibrate and remove all foreign matter from its surface. The cleaning and bio-fouling prevention is done concurrently with oceanographic parameter measurements made by the sensor. Also, it should be noted that when the transducer is vibrated at or near its resonant frequency at a level below the cavitation threshold, the transducer and sensor system deters all bio-fouling from adhering to the sensor surface.

The performance of the system is evaluated by the application of a repeater jammer signal within the cutoff range of the proximity fuze which is mounted in a free space test site. Beyond the cutoff range, the vulnerability of the proximity fuze is tested by the application of an unlimited number of modulated interference jamming signals which simulate approach and intercept of interference jamming sources.

Abstract: The electric monomicrostrip dipole antenna is a family of new electric mistrip antennas. The electric monomicrostrip dipole antenna consists of a thin electrically conducting element formed on one side of a dielectric substrate; the ground plane being on the other side of the substrate. The length of the radiating element is equal to the length of the ground plane, and the width of the ground plane extending beyond each side of the element at the width of the element (e.g., approximately 1/8 wavelength) to provide an isotropic radiation pattern. The thickness of the substrate to a large extent determines the bandwidth of the antenna, and the length of the conducting element and ground plane determines the resonant frequency.

Abstract: A dynamic wave energy extraction system utilizing a suspended weight to extract energy from ocean waves. A spring-biased floating sheave is disposed to move with respect to a pair of guide posts attached to a ship. A cable having a submerged weight attached to one end thereof passes across the sheave and attaches at the other end to the ship. The spring, cable and weight are tuned to match the predominant heave frequency of the ship, thereby exciting the cable system producing maximum dynamic tension variations in the cable. The tension variations force the floating sheaves to move along the guide posts in an oscillatory or reciprocating manner, thus extracting the maximum amount of energy from the waves.

The low physical profile of the antennas and the assembly hollow conformal arraying capability about an aircraft body without disrupting the aerodynamics of the vehicle. A phase difference of 90.degree. between two elements of the UHF antenna system is used to obtain a wider bandwidth with good matching and also improves the radiation patterns of the array. Button type tuning capacitors in each of the elements of the UHF array permits compensation for variations in the center frequency of the UHF antenna system that are caused by the variation in the substrate dielectric constant, fabrication processes, etc.

Abstract: A digital numeric VHF omnidirectional range (VOR) bearing indicator for piding a stable digital readout of VOR bearing in the presence of noise and fading signals. The device utilizes a count averaging scheme for calculating VOR bearing over a plurality of cycles. High quality filtering is also achieved by the use of phase lock loops which are used to generate low noise digital signals having a phase which matches reference and variation signals, representing VOR bearing. An exclusive "OR" gate is used to compare the reference and variation signals, after they are divided in frequency, to produce a composite signal which has a duration indicative of VOR bearing. The composite signal is then clocked, counted and averaged over a number of intervals and fed to a digital display device.

Abstract: Twin electric microstrip dipole antennas consisting of thin electrically ducting rectangular shape elements formed on both sides of a dielectric substrate. In these antennas the element on one side of the substrate is the mirror image of the element on the other side of the substrate. Each of the elements act, in effect, as a ground plane for the other. The thickness of the substrate to a large extent determines the bandwidth of the antenna and the length of the conducting elements on both sides of the substrate determines the resonant frequency.

Abstract: A coupled fed magnetic microstrip dipole antenna consisting of a thin eleically conducting, rectangular-shaped radiating element (resonator) and a nonradiating coupler formed on one surface of a dielectric substrate, the ground plane being on the opposite surface. The radiating element has one end shorted to the ground plane. There is only a single mode of oscillation. Oscillation takes place along the length of the radiating element, and the length determines the resonant frequency. The feed point is normally located at the end of the coupler; energy is in turn coupled to the radiating element. However, the feed point can be located along the uncoupled edge of the coupler. Input impedance matching is determined by a combination of the coupler length and the separation between the coupler and the radiating element, and also the feed location when fed along the uncoupled edge of the coupler.

Abstract: Circularly polarized microstrip antennas consisting of thin electrically ducting, square-shaped radiating elements formed on one surface of a dielectric substrate and having a ground plane on the opposite surface of the substrate. Two feed points are used to provide a circular polarized radiation pattern. The feed points are located along the centerlines of the antenna length and width or along the diagonal lines of the element and the input impedances can be varied by moving the feed points along both centerlines or both diagonal lines from the centerpoint of the element. The antennas can be notched in from the edges of the radiating element along the centerlines of the element width and length, or along opposite diagonal lines of the element, to the optimum input impedance match feed point.
