Abstract: A thermo-electric valve for scuttling floating devices comprising, a cyliical sleeve affixed to and passing through a bulkhead separating a pressurized medium on one side from a lower pressure space on the other side, a piston moveably mounted within the sleeve bore and exposed to the pressurized medium having a portion thereof blocking the sleeve bore, an O-ring sealing the gap between the piston head and the sleeve bore, a fully compressed spring pressing against the piston, a rigid dielectric washer and a low power resistor holding the piston against the spring. In operation a low current is passed through the resistor, disintegrating it which releases the spring's stored energy. This actuates the valve by expelling the piston which allows the pressurized fluid or gas to enter the lower pressure space.

Abstract: Apparatus for seating a very small socket contact in an electrical connector from the front side of the connector. Opposing flexible fingers, which are disposed above and below a flat wedge member and separated thereby, are extended longitudinally by plunger action beyond the wedge member which is fixed relative to the tool housing. The opposing fingers have a bend which causes their ends to come together when the fingers are extended relative to the wedge. The extended fingers and the wedge may freely be inserted into an individual socket contact from the front of the connector. Retraction of the fingers by spring bias causes the wedge to separate the ends of fingers so that knuckles at the ends of the fingers internally grasp the socket contact which may then be pulled for proper seating.

Abstract: A transducer of acoustic energy through a water medium is fabricated in a manner which assures high reliability yet significantly reduces cost per unit by including modified conductive elements. A pair of flat conductors are interleaved sinuously through a ferroelectric stack in a mutually orthogonal relationship. The conductors are so interleaved as to electrically couple the elements of the ferroelectric stack in parallel in accordance with proven transducer design. At least one rod axially extends through the sandwiched ferroelectric elements and conductors to hold them in compression and to assure a reliable electrical connection for producing an integral hydroacoustically cooperating structure.

Abstract: A method and apparatus is provided for detecting and rejecting spurious sals that may arise in incoming data. A remotely disposed data producing sensor for each sensor data channel and a single blind data channel extend to a receiver or a recorder. A data link is provided linking each sensor channel to the recorder and a one-shot multivibrator generates a sensor channel pulse whenever a signal having less than a predetermined rise time and exceeding a predetermined magnitude comes through the sensor data channel. Another one-shot multivibrator coupled to the blind channel generates a blind channel pulse whenever a signal satisfies the same conditions as for the sensor channel. An AND gate associated with each sensor data channel initiates an interruption of the data link for the duration of a coincident receipt of the sensor channel pulse and the blind channel pulse to connect a d.c.

Abstract: A sphere with a hole through one diameter is held in a spherical chamber hin a tube. The axis of the tube and the hole through the sphere are out of alignment by some predetermined angle, .theta.. The sphere is held within the chamber and the entire unit is caused to spin. The sphere is released while the unit is still spinning. The gyroscopic nutation of the sphere causes the spherical bore to traverse the angle .theta. and align with the tubular bore in a time dependent upon the sliding friction between the material of the sphere and the material of the spherical chamber.

Abstract: An erodable spin turbine having a plurality of turbine blades affixed to the outer periphery of a missile nozzle. When the missile is fired in its launch tube the exhaust gas stream flows across the turbine blades to impart an angular torque to the missile as it traverses the launch tube. As the missile traverses the launch tube the exhaust gas stream is also eroding the spin turbine such that when the missile exits the launch tube the missile has reached its terminal spin rate and the spin turbine is effectively eroded so that it no longer interacts with the exhaust gas stream. The spin rate of the missile in its free-flight trajectory is maintained by airflow over canted fins and canards mounted on the missile's airframe.

Abstract: A load-unload device is disclosed for use in a vertical conveyor system hng means for sensing a jam condition between a downward moving conveyor tray and an article that has failed to remove from the load-unload device. The device includes linkage means for creating an over-center locked condition automatically releasable at a preset force. A spring receives the load due to a jam and develops the force necessary to unlock the linkage and allow the platform to move to a position for relieving the overload. A limit switch opens the conveyor drive motor down circuit as the platform moves. Provision is made for presetting a limited amount of platform movement without shutting off the conveyor.

Abstract: A method and a device for the detection of trinitrotoluene (TNT) in efflu water from the purification apparatus of ammunition plants is described. The tube detector utilizes a basic oxide section to convert the TNT to its Meisenheimer anions, followed by an alkyl quaternary ammonium chloride ion-exchange resin which collects the colored anions. The length of the resultant stain is proportional to the concentration of TNT in the water.

Abstract: This invention improves on explosively actuated cable cutters in that it orporates a remote capability of activating the cutter. The improved apparatus comprises an acoustical transducer for receiving a remote coded signal, an electric circuit designed to detect the specific coded signal, a motor and gear mechanism which is initiated upon detection of the remote coded signal to activate the explosively actuated cable cutter.The electronics and motor compartment are hydrostatically sealed and pitted with a pressure switch and a water intrusion fail-safe circuit. The pressure switch is designed to inactivate the apparatus beyond a preset ocean depth, and the water intrusion fail-safe circuit is designed to detect any seawater seepage into the sealed electronics compartment. Upon the detection of such seepage the intrusion fail-safe circuit disconnects the system from the battery thereby removing danger of premature triggering of the cable cutter.

Abstract: A deep depth underwater simulator is illustrated for determining the dual effects of nuclear type underwater explosion shockwaves and hydrostatic pressures on a test vessel while simulating, hydrostatically, that the test vessel is located at deep depths. The test vessel is positioned within a specially designed pressure vessel followed by pressurizing a fluid contained between the test and pressure vessels. The pressure vessel, with the test vessel suspended therein, is then placed in a body of water at a relatively shallow depth, and an explosive charge is detonated at a predetermined distance from the pressure vessel. The resulting shockwave is transmitted through the pressure vessel wall so that the shockwave impinging on the test vessel is representative of nuclear type explosive shockwaves transmitted to an underwater structure at great depths.

Abstract: A device is described using at least one polyconductor film as an active ment lens of an electrical circuit for detecting incident laser radiation. In several alternative embodiments, a polyconductor film is located at the focal point of at least one lens which focuses the incident laser radiation on the film. The polyconducting film acts as a variable resistor of a balanced bridge network and upon receipt of radiation causes an imbalance in the bridge for radiation detection. The film changes phase with increasing incident power such that it protects itself against high levels of radiation. The lenses can also be polyconducting films and another film shielded from the radiation may be included to compensate for temperature fluctuations and maintain circuit sensitivity.
