Abstract: Two distinct projectile stages are employed in a projectile configured to be fired at a remote target from a rifle, grenade launcher, gas gun or the like. A first stage comprises a pair of wire tethered contact darts for applying an immobilizing electrical discharge to the target. The second stage comprises a battery, circuits, transformer and wires used to generate a high voltage pulsed signal and apply it to the contact darts in the first stage. The higher mass of the second stage impacts the lower mass first stage at launch causing the first stage to be propelled to the target while the slower second stage hits the ground short of the target.

Abstract: A high-speed supercavitating underwater vehicle includes an elongated hull of circular cross section, the hull having a cavitator at a forward end thereof and means for ventilating gas to form a cavity around the hull in underwater travel. An expandable annular skirt is fixed on the hull and is provided with an outer surface proximate an outer surface of the hull. The skirt is expandable to increase a diameter of the skirt from proximate a diameter of the hull to proximate a diameter of the cavity to define an annular gas film between the expanded skirt and a boundary of the cavity. The expanded skirt acts to substantially reduce the flow of gas from a forward high pressure zone of gas to an after low pressure zone of gas.

The booth includes a housing formed of armored material and proportioned to be able to enter the doorway of a building. The housing has armored windows and gun ports. The housing has wheels and may be moved from place to place by the occupant walking inside of the housing.

Abstract: A safing and arming device is provided for a warhead or round which is to be launched by a rifled gun and which includes submunitions. A slider is disposed in a housing between a detonator and lead cup and is movable between a first, safe position wherein the slider acts as an interrupter and a second, armed position wherein an opening in the slider is in alignment with the detonator and lead cup. A setback sensor initially locks the slider in the safe position and then, responsive to a setback force produced at gun launch, unlocks the slider. An ejection sensor also initially locks the slider in the safe position and continues to lock the slider against movement to the armed position during a period between gun launch and exiting of the warhead from the gun. Responsive to the ejection force produced at exiting of the warhead from the gun, the ejection sensor unlocks the slider to enable movement thereof to the armed position.

Abstract: A device supplies electric energy for projectile detonators without a battery or additional energy generation during flight of the projectile. For operating the projectile detonator in the flight phase, a supply capacitor charged during an inductive programming phase is disposed. The capacitor has a very low leakage current in order to bridge a time in the range of minutes between the programming and the start of the flight phase without significant energy loss. The charging of the supply capacitor takes place through halfwaves, of a programming AC voltage not utilized in the programming and not under load.

Abstract: A low observable, brass ammunition cartridge casing with an exterior surface having a colored coating which renders the cartridge casing low observable. The colored coating may be deposited onto the exterior surface by various processes, such as electroplating, chemical deposition, and spray painting. The colored coating may be selected from a variety of different colors such as, black, olive green, silver, brown, tan, gray, and white. The colors are typically obtained using conventional pigments and colorants, such as metal oxides. The brass casing exterior surface may be roughened to reduce the gloss or sheen of the casing on the colored coating. The invention includes ammunition cartridges containing a low observable brass casing described above.

Abstract: A pyrotechnic igniter arrangement, especially for occupant protection devices in motor vehicles, includes a single common carrier substrate, an electronic assembly arranged on the carrier substrate in an electronic zone, an electrically ignitable ignition bridge arranged on the carrier substrate in a pyrotechnic zone, and a pyrotechnic charge in the pyrotechnic zone. A mechanical decoupling or parting feature, such as a frangible link or an elastically bendable neck, is provided in the carrier substrate between the pyrotechnic zone and the electronic zone, so that forces arising during ignition of the pyrotechnic charge are not transmitted through the carrier substrate into the electronic zone. The decoupling feature breaks or elastically yields when a load exceeding a prescribed threshold is applied thereto. The electronic assembly is protected from damage due to excessive loads, and remains functional even after ignition of the pyrotechnic charge.

Abstract: A lightweight multiple missile launch assembly (10) adapted to carry newer heavier Maverick missiles (AGM-65D, E, F, G or K). The invention is illustrated with a BRU-33, 55 or 57 bomb rack (12) adapted to carry two LAU-117 missile launchers (24, 26). The missile launchers (24, 26) are secured to the bomb rack (12) with a suspension unit (20, 22) of unique and novel design. The suspension units (20, 22) allow for releasable engagement of the missile launchers (24, 26). This allows for different missile packages to be deployed in the field.

Abstract: An igniter arrangement for vehicle occupant protection devices includes a substrate, an electronic assembly on the substrate in an electronic zone, an electrical ignition bridge on the substrate in a pyrotechnic zone, and a pyrotechnic charge adjoining the ignition bridge. A shock absorbing elastic first material covers a first portion of the substrate in the pyrotechnic zone, and forms a shock-absorbing cushion between the charge and the electronic zone. A second material harder than the first encases a second portion of the substrate and the electronic assembly in the electronic zone, protects the electronic assembly, and separates the two zones. The ignition bridge and the electronic assembly are at opposite ends of the elongate substrate. A breakable parting feature separably connects the two substrate portions and breaks due to high forces arising during ignition of the charge, so these forces are not transmitted through the substrate into the electronic zone.

Abstract: Effects of capacitive resistances on the transmission of data between electronic igniters of an ignition system and a device for programming and triggering igniters are avoided by the disclosed method. Prior to a planned communication of an igniter with the device, a dc voltage is applied to the ignition circuit for a predetermined length of time. This voltage is higher than the voltage provided for generating the signals with which the data are generated. Subsequently, the signals that the igniter transmits in response are produced with a lower voltage than the previously elevated voltage and the dc voltage is increased once again prior to the response to an additional igniter.
