Abstract: A flying target control system for directing a flying target along a radio eam heading toward a ship under simulated attack according to a preselected altitude and speed profile. The control system utilizes a TACAN transceiver which receives TACAN signals emitted from the ship under simulated attack. The TACAN transceiver produces an azimuth signal to steer the target via an automatic pilot toward the ship under simulated attack and a range signal which is used to address a profile storage device. The profile storage device produces altitude profile control signals and speed profile control signals according to the range of the target from the ship which are fed into the automatic pilot to guide the target along its preselected altitude and speed profile.

Abstract: A fluid pressure power plant which converts heat energy, externally generated, to high hydraulic pressure. The system generates heat energy in the form of steam or hot gas, supplies the heat energy to a double-acting intensifier piston which converts the heat energy to high hydraulic pressure which is stored in an accumulator. The high pressure hydraulic energy stored in the accumulator is used to drive hydraulic motors or turbines through hydraulic output control valves. The system operates on a demand cycle in that no energy input from the heat generator and power conversion piston is necessary until there is some demand for power output from the hydraulic accumulator, once said accumulator is fully charged.

Abstract: A self-contained acoustic beacon activated by a seawater switch for provig an independent method of locating and recovering a floating or submerged recoverable target. The device provides an ideal operating life for target recovery of about 36 hours as well as providing an extensive underwater range. The device also provides stable frequency operation without a crystal-controlled oscillator over a wide range of source voltages allowing use of inexpensive batteries as a voltage supply source. Additionally, the signature or output signal code of the device can be changed simply and quickly providing positive identification of the acoustic beacon and lengthened operating life span.

Abstract: A detector for locating the direction of propagation of transients on eleical power lines supplying critical loads having various types of random impulse voltage transients. The device detects the polarity of transient voltages and the direction of transient current. An integrated logic and control circuit compares the sampled voltage and current to indicate from which direction the transient came. The logic and control circuit activates indicator lights which show whether the transient occurred in the direction of the source or the load and whether the transient was positive or negative.

Abstract: A device for use in an active-passive fuzing system to guard against the functioning of the fuze due to jamming signals transmitted by the target. A gate circuit is utilized to prevent an enabling signal to be passed to the warhead detonator until there is jamming signal fall-off in the guard detector and there is an increase in signal strength in the passive detector.

Abstract: An ogival explosive warhead lens, nearly hemispherical in shape, construc in the form of four coaxial spheroidal shells containing different explosives which when initiated at a point on the curved surface near the flat base, will result in detonation waves converging to a line on the opposite curved surface lying in a plane which passes through the axis of symmetry.

Abstract: An angular tracking servo system for passive tracking of the sun which utzes solar radiation to control the attitude of a mirror element in an array of Fresnel reflectors. The array collects and focuses solar energy onto a high efficiency conversion device. The energy required to move the mirror element is supplied by a gear system which is attached through a pivot arm to a vertically moving float immersed in a chamber containing water.

Abstract: A transient direction detector which indicates the occurrence of power line ransients and their direction of propagation. The system is comprised of current and voltage sensors, a logic and control circuit which receives the transient current and voltage sensed and provides an output to an indicator circuit to show the direction of any transients on a power line. The current sensing circuit receives an input from an induction coil on an iron clamp around a power line. The voltage sensing circuit receives its input from a voltage sampling transformer directly connected across a power line. The logic and control circuit determines where the transient occurred by comparing the polarity received from the transient current and voltage sensing circuits.

Abstract: A diagonally fed electric microstrip dipole antenna consisting of a thin ctrically conducting, rectangular-shaped element formed on one surface of a dielectric substrate, the ground plane being on the opposite surface. The length of the element determines the resonant frequency. The feed point is located along the diagonal with respect to the antenna length and width, and the input impedance can be varied to match any source impedance by moving the feed point along the diagonal line 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. Singularly fed circular polarization is easily obtained with this antenna.

Abstract: An offset fed electric microstrip dipole antenna consisting of a thin eleically conducting, element formed on one surface of a dielectric substrate, the ground plane being on the opposite surface. The length of the element determines the resonant frequency. The feed point is located along one edge of the antenna length and the input impedance can be varied by moving the feed point along the edge of the antenna to obtain optimum match for the resonant mode without affecting the radiation pattern. The antenna bandwidth increases with the width of the element and spacing between the element and ground plane. Slanting one end of the element will provide a slightly wider bandwidth.

Abstract: A coupled fed electric 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. 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. Input impedance matching is determined by a combination of the coupler length and the separation between the coupler and the radiating element.

Abstract: Apparatus and method for cleaning soldering irons in which a soldering tip of the type having capillary passages is provided with a tiny passageway through the wall of the tip into the upper portion of the capillary passages through which solder and other debris can be expelled from the tip by vapor pressure. Solder collected by capillary action in a cavity in the tip is expelled through the tublar passageway communicating with the capillary passageways when the working end of the soldering tip is pressed lightly on a moistened sponge. The sponge is mounted in a receptacle which has first and second reservoirs containing water and high temperature oil, respectively. The sponge is kept moist by a wick which extends down into the water. The reservoir containing the high temperature oil has a small access hole which supports a soldering iron with the tip substantially submerged in the oil when not in use.

The device comprises a housing having an inlet port, an outlet port and a pair of offsetted walls. The oil-water mixture enters the housing parallel to the offsetted walls. A pair of concavely curved walls having an apex adjacent the inlet port splits the entering oil-water mixture into two sub-jets. Each sub-jet enters a bounded region where oil is separated from the water before the oil-water mixture exits the housing.
