Abstract: A fuzing device for a submunition or munition comprises an airtight housing ontaining a pressure chamber communicating through an orifice to a diaphragm with a firing pin attached thereto. The fuze is actuated by pressurizing the chamber with gas which flows through the orifice at a predetermined rate until the total pressure on the diaphragm causes it to deform sufficiently to activate a detonator.

Abstract: A low cost graze sensor fuze arrangement for a point detonating spin stabzed projectile in which firing pin actuation for detonation purposes is accomplished where the projectile may only graze the target and a graze sensor element will be laterally moved a limited amount to cam a firing pin assembly rearwardly toward a rotor armed detonator.

Abstract: A system for safely simulating artillery delivered flare illumination over roops engaged in nighttime tactical training exercises, utilizes a lifting device for carrying a tethered electrically initiated, gravity released flare dispenser system to provide illumination over a target area while substantially reducing the hazard to personnel of flare debris fallout and malfunction danger to the lifting device. A tubularly shaped flare dispenser housing member supports a plurality of reloadable cylindrically shaped parachute flare assemblies. An electrically operated parachute flare initiator is utilized to simultaneously ignite and drop-release one or more combustible case flares by severing a burn-through cord retaining member.

Abstract: An apparatus and method for measuring the liquid water content of a cloud fog utilizes an environmentally controlled test chamber having a plurality of oppositely disposed windows selected to be optically transparent at a chosen wavelength of radiation. The windows of the chamber are positioned intermediate an infrared source and a wavelength scanning radiometer. An optical band pass filter is selected to pass radiation of a specific wavelength making the instrumentation substantially independent of cloud droplet size distribution enabling the measurement of only liquid water rather than water vapor.

Abstract: 2,4- AND 2,6- Dinitrobenzenesulfonates, which may contain a methyl group in the 5 position, are reduced with sulfur dioxide in aqueous sulfuric acid medium at elevated temperatures, whereby one or both nitro groups are reduced to a primary amino group and the sulfonic acid group is eliminated.

Abstract: A multi-effect passive detonation trap utilizes a manifold having a rectalarly shaped cross sectional area with oppositely disposed off-set pipeline fixedly connected thereto to attenuate an upstream detonation wave. The detonation wave is arrested by providing for maximum containment and self relief of the energy produced, directional control of the reaction, and a manifold configuration which assures extinction of the detonation wave.

Abstract: An assembly tool utilizes a tubular bar to support and torque a pronged d-shaped work holding member on one end and a socket disposed in a knurled handle end. An alignment wheel is axially fixedly positioned on the bar proximate to the work holding member. A movable alignment ring slidably disposed on the bar intermediate the handle end of the bar and the alignment wheel is used in conjunction with the alignment wheel to help guide, insert and tighten a threaded burster retainer work piece in a projectile case while torque is applied to the tubular support bar.

Abstract: A spherical convex pusher plate member is positioned intermediate the rear end of a subcaliber tubular projectile and the forward section of a cup shaped sabot carrier to improve the ballistic performance of the projectile by reduction of a parasitic weight and faster separation of the carrier after launch. Propellant gas pressures acting on the convex spherical section of the pusher plate causes deflection thereof sufficient to force the sabot to loosen from the projectile to provide an improvement in projectile velocity.

Abstract: An electromechanical coded actuator, upon receipt of the proper combination f electrical pulses, will unlock and cause angular displacement of an output shaft. The device comprises a rotatable notched flange integral with the output shaft, the former being keyed to the housing by a series of flat blades axially movable against a bias. A first solenoid sequentially positions a rotatable index arm over each blade, whereupon a second solenoid actuates the index arm to displace and lock selected blades in a manner to align a notch in each blade with the flange. The latter is then free to be rotated via a clutch-type coupling with the first solenoid. Additional actuation of the rotary solenoid releases the clutch allowing the flange and shaft to be returned to its original position by a spring bias, and also releases the displaced blades to lock the flange. An electrical switch actuated by the index arm defines the zero position.

Abstract: A method of recovering o-chlorobenzilidene malononitrile from finely divi particulate mixtures thereof with colloidal silica. The mixture is contacted with a solvent such as methylene chloride, in which the o-chlorobenzilidene malononitrile is highly soluble and the colloidal silica is insoluble, the resulting solution is filtered to remove the insoluble colloidal silica, and the o-chlorobenzilidene malononitrile is crystallized from the filtrate.

Abstract: A short-range training practice round, for simulating a high energy type unition round, comprises a discarding-sabot containing a self-destruct subprojectile, e.g. of aluminum or steel, similar in external configuration to the heavy armor-piercing subprojectile simulated, and made up of a plurality, e.g. 3, of contiguous elongated mating segments held together during launch and subsequent flight by a heat-sensitive nose cap adapted to be heated by the airstream and disintegrate at a predetermined point in flight, allowing the segments to tumble in air, decelerate, and come to rest after a short flight.

Abstract: A cartridge magazine including a spiral channel having a tangential linear xit section, a plurality of spider arms dividing the cartridges into groups of cartridges and having a plurality of indentures in their radial faces, and a drive means mounted external to the magazine for driving said arms. The spiral is a perfect Archimedian spiral and the indentures on an arm number one less than the number of cartridges in a group and are displaced radially by the diameter of a cartridge.

Abstract: The adhesive bond test apparatus comprises: a U-shaped bracket of aluminum, upported on a table; a tiltable rectangular panel of aluminum pivotally mounted in the U of the bracket for tilting between a horizontal and a vertical position; a sheet adherend made of two Kraft paper layers bonded together with asphalt, attached to one surface of the panel; a plurality of elongated strips adherends each having a specified weight attached to one end, and the other end bonded over a given small area to a portion of the sheet adherend that will be up in vertical position, wherein the weight applies a constant gravity load to the bond during the test. Both shear and a pull tests are disclosed.

Abstract: A coating of refactory metals alloy, e.g. an alloy of tantalum and tungsten, is deposited on a substrate, such as the bore of a gun barrel, by reacting an alloy of the refractory metals with chlorine to form a mixture of the vapors of the refractory metal chlorides and reacting the resulting mixture of vapors with hydrogen to reduce the metal chlorides to the free metals. The alloy coating thus deposited possesses a finer grain structure and is more homogeneous and ductile than one obtained by chlorinating the tantalum and tungsten metals separately.

Abstract: A strong electrical signal, occurring at the same time as a relatively wer electrical signal of substantially the same frequency, is suppressed by a method utilizing apparatus wherein (a) the signals are amplified both linearly and non-linearly simultaneously in separate amplifiers, and (b) the outputs of the amplifiers are subtracted from each other while the gain is adjusted in at least one of the amplifiers until the stronger signal is amplified to the same amplitude in each amplifier, leaving the weaker signal isolated as the resultant difference.
