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: 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: The invention concerns a red powder composition that is substitute for contional black powder. It can be loose or consolidated forms. In a four grain combination, the red powder can be used as the propelling charge in hand-held rocket signals or flares. There are new methods for preparing the powder and new methods for fabricating articles. The chemical composition of red powder is a dispersion of phenolphthalein, alkali metal nitrate and sulfur in a binder of phenolphthalein salt.

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: The invention provides a method of degrading nitrate esters by exposing a spension of a nitrate ester to a combined culture of Sclerotium rolfsii ATCC 24459 and Fusarium Solani IFO 31093. This allows an alleviation of environmental difficulties associated with the demilitarization of nitrocellulose base gun propellants and for the bioremediation of soils contaminated with such nitrocellulose based materials.

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 compound 2,4-dinitroimidazole is highly insensitive towards impact and its thermal stability is excellent. The calculated detonation properties results indicate that its performance is about 30% better than TATB. It can be prepared easily with good yield starting from inexpensive starting materials. Results from impact sensitivity, friction sensitivity time-to-explosion temperature and vacuum stability tests indicate that 2,4-dinitroimidazole is less sensitive than both RDX and HMX. Its good oxygen balance and measured heat of formation data of this material indicate that its propellant performance is good.

Abstract: An augmented electromagnetic accelerator apparatus which imparts an initial elocity to a projectile by use of enhanced inductance gradients and allows for the use of cylindrical projectiles by the use of a round bore, using a parallel gun rail geometry The enhanced inductance gradients are achieved by the use of an extra turn around the gun rails and enclosing the rail and the said augmented turn in laminated iron. The augmented accelerator has crossovers at the two ends (breech and muzzle end) which have minimum influences over the electromagnetics in the bore of the accelerator.
