Abstract: A respiration test method for providing accurate test signals which may be sed to measure the duration of a subject's inhalation and exhalation periods, and electronic timing circuits for performing such methods. The circuit includes a clock and two flow detectors. One flow detector senses inhalation while the other senses exhalation of a subject. A logic circuit selectively transmits clock pulses from the clock to an inspiratory clock output and an expiratory clock output. The flow detectors generate two-state inhalation and exhalation signals that are at a first state during the duration of the respective inhalation and exhalation periods plus a small timing-out period. The logic circuit, which is connected to clock and the flow detectors, transmits the clock pulses from the clock to the inspiratory clock output when the inhalation signal is at the first state, and to the expiratory clock output when the exhalation signal is at the first state.

Abstract: A statically stable limited range projectile utilizes a fin assembly combd with a cylindrical body and low drag ogival front end to ballistically match the limited predetermined range flight characteristics of a standard round.

Abstract: The invention offers a novel way to enhance the time of a surveillance paad over a target area. It provides a relatively inexpensive way to position an unmanned reconnaissance payload over a potential target area, using a cargo projectile launched from a conventional tubed artillery piece, under all weather and environmental conditions. The use of tow line between the ejected reconnaissance payload and the ballistic cargo projectile allow the payload with its parafoil to achieve a greater height, enter an orbit and extend a longer time over the target area.

Abstract: A device is presented for measuring residual stresses in a solid component. he device includes a hardness measuring component which has an indenter for determining hardness at various locations. Stress (.sigma.) data is obtained by converting the hardness measurements according to the formulaa.multidot.[.sqroot.4P.sub.o.sup.2 -3P.sup.2 -P],where a is a constant in Kbar.sup.-1 mm.sup.2 /kg, which depends on the type of material under test and also on the type of indentor used, where the pressure p is measured in kg/mm.sup.2, and where the average pressure p.sub.o is the average value of mean pressure p along a radial cut line of the solid component specimen.

Abstract: A portable lightweight mortar utilizes a triangularly-shaped canvas base te designed to withstand the high resolved tensile loading stresses generated by mortar firings and transmitted to it by three truss rods which are disposed in grommets located in the canvas corners on one end and are attached by pin/trunnion swivels on its other ends to a gimbaled collar located on the cannon tube.

Abstract: A multi-dimensional decoy uses a non-combustible exterior to support a reive interior metal film in the form of a rapidly inflatable balloon to generate an infrared and radar signature to match the thermal and radar profiles of an intended target.

Abstract: A gun bore evacuator comprised of a main reservoir surrounding the gun tu a bore in the tube, ports between the main reservoir and the bore, an auxiliary reservoir surrounding said tube, ports between said main reservoir and the bore, ports between the auxiliary reservoir and the bore, and check valves between the reservoirs.

Abstract: A cover or apron interposed between a ballute and the aft cover of a submtion for delaying deployment of the ballute and preventing the ballute from contacting the aft cover during deployment.

Abstract: The invention relates to a fuze for a submunition grenade which will selfstruct electrically in the event that the mechanical primary inertial functioning mode fails to operate upon striking an intended target.

Abstract: The disclosure describes photochemical synthesis of halogenated polycarboxycubanes from simple carboxycubanes and an oxalyl halide. It is possible to synthesize 6-Chloro-1,2,4,7-tetracarbomethoxycubane and 2-Chloro-1,3,5,7-tetracarbomethoxycubane. Photochemical synthesis of halogenated polycarboxycubanes from carboxy cubane and an oxalyl halide is reported.

Abstract: Disclosed is a method for reducing dispersion in gun launched projectiles. n axial thrust is applied to the projectile at a specific time in the yaw cycle to cancel the effect of aerodynamic jump which arises from the effect of yawing motion disturbance created by an initial disturbance.

Abstract: A resettable bore obstruction detector indicator is positioned on the muz end of a gun bore to indicate whether the gun bore is free from obstruction after a round has been loaded.

Abstract: The disclosure is of an artillery projectile including a projectile body taining, among other things, a rocket motor at the front of the projectile and coupled to nozzles in the body of the projectile through which burning propellant gases flow.

Abstract: Disclosed is an improved method of preparation of trifluoromethylthiocopper n a very highly purified state and its application to the synthesis of organic and inorganic compounds containing the trifluoromethylthio moiety. Biological testing has shown that dimethyl(trifluoromethylthio)arsine is one of the most potent lung irritants known.

Abstract: A method for internal laser welding of metallized optical components for attachment of optical fibers which comprises the steps of: milling a "V" groove in one end face of a fiber carrier; aligning an optical fiber in the "V" groove; polishing end faces of an integrated optics chip and the fiber carrier assembly; depositing chromium layers on integrated optics chip and the fiber carrier assembly; depositing eutectic alloy on chromium layers; optically aligning the optical fiber and a wave guide in the integrated optics chip; and applying a pulse laser beam for an internal laser weld between the end face of the integrated optics chip and the end face of the fiber carrier assembly.

Abstract: A cylindrical device connected to the nose of a projectile for imparting n to the projectile fired from a non-rifled bore of a cannon. The device has at least two coaxial, adjacent, and integrally connected cylindrical segments of different diameter. The segment having the larger diameter is positioned most rearwardly of the projectile, relative to the nose of the projectile, and the periphery of this segment has circumferentially spaced angled slots for catching air moving past the projectile to spin the projectile. The segment with the smaller diameter attaches the cylindrical device to the aft end of the nose of the projectile and directs the flow of air to and through the angled slots of the segment having the larger diameter.

Abstract: An ignition device for propellant of a projectile having its aft section ending deeply rearward within a shell case comprises a strand holder, a primer head, and flexible ignition strands with the primer head, when installed, being supported by the shell case and supporting the strand holder which in turn preferably supports the aft end of the projectile. The ignition strands, symmetrically disposed, contact the propellant and in preferred embodiments also contact the projectile, and/or the interior of the shell case, as well as the propellant, and extend along the body section of the strand holder and through conduits therein into a combustion chamber, formed intermediate the installed primer head and a platform section of the strand holder, and with the combustion chamber containing an igniter booster charge susceptible to ignition by a firing means adapted to be used with the primer head.
