  • Patent number: 5192830
    Abstract: A sabot for a shotgun shell provided with a recess in its base upon which opellant gases may act to radially expand and flatten the sabot thereby enhancing the dispersion of shot. In alternate embodiments the recess may be conoidal, parabolic, pyramidal, or an involute surface resembling a cone. The recess may also be comprised of multiple overlapping layers. Each recess provides a unique shot pattern for short-range antipersonnel engagements. In other embodiments, the foregoing recesses are provided with grooves to facilitate petalling of the recess and flattening of the sabot during and after launch. In another embodiment, the recess is filled with propellant and capped with a consumable plug to delay ignition of the propellant charge, further enhancing shot dispersion.

  • Patent number: 5192827
    Abstract: A high power microwave/radio frequency radiating projectile that stores electrical energy in a Pulse Forming Line network. Electrical energy is converted to high power microwave/radio frequency energy by a subnanosecond switch either in a single pulse mode or a repetition rate mode.The high power microwave/ratio frequency energy is then radiated by an antenna built into the projectile. The heavy power supply required for providing the high voltage necessary for charging the pulse forming line network is not part of the projectile but is contained in the launching gun, or as ancillary equipment to the launching gun.

  • Patent number: 5189375
    Abstract: A technique and apparatus for measurement of resistances of 0.01 ohm and s without disconnection from the circuit. The invention is used for measurement of degradation in cable shields by measuring the droop caused by circuit resistance in an induced current pulse in the undisconnected circuit. The method can also be used for measurement of junction resistances in high current circuits such as auto starters. The invention allows measurements to be made with the circuits connected so that the faults are present in the measurement setup. The method includes inductive coupling of long duration repetitive current pulses onto the circuit under test, measurement and display of induced current pulses, and display of induced current pulses on an oscilloscope.

  • Patent number: 5175391
    Abstract: A shaped charge device having a cylindrical housing, an explosive charge with a cavity at one end, a fuze, booster, a multimaterial vertically layered liner having a hemispherical, semi-hemispherical, arcuate or conical shape with a number of segments of materials, each segment in contact with the explosive charge and the cavity, each segment oriented normal, parallel or oblique to the charge axis. The detonating of the explosive charge causes the liner to form a jet of a plurality of the segments.

  • Patent number: 5164919
    Abstract: A sonar sensor comprising a substantially non-corrodible housing and a fluidic gainblock disposed therein. In addition, one or more fluid-filled laminar proportional amplifiers are arranged either in series or in parallel and contained within the fluidic gainblock. Means are provided to produce a jet within each laminar proportional amplifier, which is then modulated by incoming acoustic signals. The pressure caused by diverting the jet from its equilibrium path is proportional to, but greater than, the incoming acoustic signal. Hydrophones are used to convert the amplified acoustic signal into an electrical signal. In one embodiment, the fluidic gainblock is free-flooded and open to the liquid environment in which it is used, obviating the need for pressure equalization. In another embodiment, the fluidic gainblock is provided with filtering means for prevent the accumulation of sediment within the cavities making up the laminar proportional amplifiers.

  • Patent number: 5162118
    Abstract: An apparatus for the production of high density, monolithic ceramic maters. A mixed powder, such as Titanium-Boron is first subjected to uniaxial pressure to form a green compact. The compact is positioned in a vented mold between two steel plates and subjected to Self-Propagation High Temperature Synthesis to form a molten ceramic, and then to an explosively generated shockwave by an explosive charge positioned on the upper steel plate so as to compress the molten ceramic between the two plates to form high purity ceramic of more than 90% theoretical density.

  • Patent number: 5155619
    Abstract: A multi-channel/multi-layer optical gate contained within a fiber-optic housing having any number of optical cells disposed within the housing. The optical cells are made up of non-linear organic polymers surrounded by a piezoelectric crystal, which is in turn connected to a photovoltaic device. When the photovoltaic device is activated, the piezoelectric crystals cause the non-linear organic polymers to change their refractive index, causing an interruption of a reference laser beam. An output detector is disposed within the fiber-optic housing for detecting the reference laser beam.

  • Patent number: 5154797
    Abstract: A shadow mask for sputtering is formed from a single crystal silicon wafer which is mechanically and chemically polished to produce top and bottom surfaces which are substantially flat and parallel to one another. The wafer is provided with one or more pyramidal etch pits which are arranged in a pattern. Each pit has a substantially square cross-section on the top surface, and a smaller substantially square cross-section on the bottom surface to produce an aperture in the wafer. In use, the wafer is clamped against a flat substrate with its apertures opening toward the evaporant beam. After use, the deposited species may be cleaned from the wafer using suitable etchants which render the wafer unharmed, and therefore reusable.

  • Patent number: 5132860
    Abstract: An erasure system for magnetic information storage media is disclosed by which magnetic media, such as computer, video and audio tapes, cassettes and discs, can be thoroughly erased. The system uses high energy product permanent magnets preferably positioned so that their poles repel one another to induce "bucking magnetic fields" having lines of force active in the three spatial planes and parallel or tangential to the recorded signal track on the media being erased. The DC magnetic field thus applied causes the DC erasure of the media. The AC erasure effect comes about through the relative movement of the media through fixed magnetic fields of opposite polarity, causing the magnetic media to be subjected to a reversing polarity of magnetic saturation. The magnet configurations can be adjusted for use on helically recorded magnetic media, in addition to cross-field and conventional recording techniques.

  • Patent number: 5122803
    Abstract: A method and apparatus of imaging moving targets with an aircraft mounted complex radar system has a plurality of independent, but synchronized synthetic aperture radars (SARs) positioned on the aircraft at equal separation distance .DELTA.x along the flight velocity vector V.sub.p of the aircraft. Frequency modulated (or otherwise coded) pulses are transmitted therefrom with an interpulse period T.sub.p, where 1/T.sub.p is an integral multiple of V.sub.p /.DELTA.x. The pulse repetition frequency, platform velocity, and spacing between adjacent SARs are all chosen to create the effect of a stationary radar momentarily fixed in space. A two dimensional complex IF (intermediate frequency) output signal is recovered by the first SAR on the aircraft. This signal is identical to that recovered by a conventional SAR. The two dimensions are fast time and downtract position. If only one point target is present, the IF output signal is the point target's phase history.
