Abstract: A lightweight linear shaped charge for explosive cutting and penetration of target, which includes a plastic linear housing in the form of a concave channel with an inverted "V" shaped metallic liner mounted within the concave channel. An explosive charge is shaped and held between the plastic housing and the metallic liner. Upon detonation of the explosive charge an explosive jet of the metallic liner is generated to cut and penetrate the target. Also, the plastic linear housing may be extended downward a short standoff distance of approximately 0.5 to 1 inch for optimum cutting and penetration of the target.

Abstract: The ground-wire detector of the invention is a portable device used to locate buried ground-wires of an energized very low frequency/low frequency antenna system operating within the frequency range of 15 kHz to 200 kHz. This ground-wire detector has an oscillator section that is tunable by a dial located on the detector. Because of this feature, an operator can change the oscillator's frequency without the need for component replacement.The detector of the invention includes two series-connected oppositely-wound coplaner coils spaced approximately 15 inches apart. The coils are oppositely wound to generate a maximum detection signal when centered over an energized ground-wire. The coils generate a detection signal when placed within the vertical magnetic fields formed by energized antenna ground-wires and are designed to incur minimal interference from the large horizontal magnetic field radiating from an adjacent transmitting antenna station.

Abstract: A method for obtaining a nuclear magnetic resonance image of a sample is performed by first placing the sample in a homogeneous static magnetic field excited with a homogeneous transmitter device. Spin magnetization in the sample is thus initially detected with an inhomogeneous receiver device such that an induced voltage in the receiver device depends on a spatial location of precessing nuclei in the sample. Then, a spatial coupling of the sample and the receiver device is varied and the spin magnetization in the sample is again detected with the inhomogeneous receiver device. The full spatial distribution of the spin density of the sample and hence an image of the sample is then determined with the spin magnetizations detected. Either the sample is moved relative to the receiver device, or the spatial coupling of the receiver device and the sample is electronically altered. Any spin interactions are eliminated by using coherent averaging techniques before the detecting steps.

Abstract: A supersonic aircraft or missile broad bandwidth antenna is provided. This antenna is constructed into a cavity created in the fuselage or wing of the aircraft and covered with a radome for flush mounting. The cavity comprises side walls and a bottom constructed of electrically conductive materials which are caused to be electrically excited by an antenna element located within the cavity. This antenna element, which is capable of broad bandwidth operation, is either passively or actively tuned. Active tuning is carried out by a logic converter circuit connected to the antenna from a communications transceiver.

Abstract: A VLF-VHF broadband in-line amplifier forms a portion of a towable buoyant able antenna system that is deployed in seawater from submarines.

Abstract: In an apparatus for helically slitting a continuous tubular film of synthetic thermoplastic material, a pair of feed rollers for feeding flattened continuous tubular film to a mandrel are mounted at fixed locations in a main frame. A rotary support mounted in the main frame carries the mandrel which consists of spaced apart low-friction bars disposed in a circular array concentric to the axis of rotation of the rotary support. A cutter is adapted to slit the tubular film as it traverses the mandrel. The axis of rotation of the support is aligned with the nip between the feed rollers approximately at the center of their length. A reversing rod and a deflecting or guide roller are connected to the rotary support for guiding the slit film from the mandrel to a winder. The winder has a winding axis aligned with or intersecting the axis of rotation of the rotary support at a right angle. A spreader for opening out the film is disposed between the feed rollers and the mandrel.

Abstract: An anti-jamming diverter comprising a kicker gate at each pocket of a mail sort machine for "kicking" the tail of a letter away from the point of entry into the pocket so that the next letter can enter the pocket without jamming. The kicker gate, when actuated, aligns with the actuated gate of the pocket to allow smooth entry of a letter from the transport into the pocket. Upon deactuation, the kicker returns to its original position thereby "kicking" the tail of the letter inwardly into the pocket.
