Abstract: An aerosol generating system for maintaining a constant concentration of aerosol in a chamber is disclosed. The system includes an aerosol generator in a closed chamber. A small fan in the chamber distributes the aerosol within the chamber. A particle analyzer connected to the chamber draws aerosol samples and analyses samples to monitor at least one characteristic property of the aerosol. Typically, these are particulate concentration and particulate size. The system includes a control responsive to signals from the analyzer representing changes in the monitored characteristic property to control operation of the aerosol generator. The control is such as to maintain the characteristic property substantially constant. The system may also be equipped with humidity and temperature control elements for maintaining these factors constant within the chamber.

Abstract: A method of defending against a warfare cloud of toxic aerosol utilizes a charged defensive aerosol which is sprayed into the cloud. The defensive aerosol is made of a defensive agent which may be chemically or biologically active. The agent is sprayed through charged nozzles to impart a charge to the aerosol. The charge should be at least several thousands of volts with respect to ground so that particles of the defensive aerosol combine and coagulate with particles of the toxic aerosol to neutralize and cause rapid settling of the warfare cloud.

Abstract: Disclosed is a new rifle receiver body for an M-16 rifle, incorporating a deflector portion adapted to divert spent cartridge cases away from the person of the user, away from the face and neck of a left-handed shooter for example. While particularly useful for the protection of a left-handed shooter, it in no way affects the use of the gun and can be used for right-handed users in the usual way. The deflector is a boss located at the rear of the ejection port, jutting out from the right side of the rifle body.

Abstract: The invention relates to lock mechanisms by which a missile or analogous tem may be prevented from undergoing an undesired launch or ignition.

Abstract: An electrical power converter comprising two current-fed square wave chops the outputs of which are combined and rectified to yield a variable and regulated output voltage. The phase relationship of the choppers are varied to achieve output voltage control and regulation. The chopper outputs are combined in such a way that the choppers never experience the open-circuit inductance of their output transformers. This enhances frequency agility. A novel choke feed system is provided in which the choke flyback energy is absorbed and then transferred to the input of the other chopper.

Abstract: This invention relates to a method for assessment of the condition, and cge of condition, of the liquid fill for chemical projectiles by analyzing the vibrational characteristics of the projectile and fill. It is a method by which the condition of the liquid fill in a projectile can be assessed without requiring cutting, drilling, and/or altering the structure of the shell or payload. This non-destructive technique can be used with projectiles filled with toxic or hazardous materials and can occur within the confines of storage buildings. The system for incorporating the method of the invention includes a projectile which is freely suspended and then struck with a device causing the projectile and the fill to vibrate. The natural vibrational characteristics of the projectile and fill are measured and recorded and can be compared to model data to ascertain any changes in the physical characteristics of the fill.

Abstract: A method of measuring the shear viscosity of a polymeric solution by measng the delayed die swell of a pressurized solution through a capillary.

Abstract: This invention relates to a system for vibration testing of specimens using n electro-dynamic shaker. It overcomes the various undesirable consequences which attend the existing technology and methodology, which uses a constant thickness flat plate platen, by using an inverted, truncated pyramid type of platen, with both the base and top of square-rectangular-parallelpiped shapes, attached to a cylindrical shaker head. The outer portion of the platen has a very low mass and the section modulus is very high at the line of bending thereby increasing the resonant frequency of the platen while lowering the total weight of the platen, because there is less mass around the perimeter of the platen. The optimum shape of the pyramid is determined by a means which can be expedited by use of the computer program.

Abstract: A snap slit door having at least one panel and a flat closure means used to reate tension in the door panel or panels, such tension acting as the closure force generated by the closure means for the door panel or panels. The flat closure means may be adjustable such that the tension and resulting resistance to opening is variable. Said door panel or panels may be of any pliable material to enable use of the panel or panels without hinges, and further to render the flat closure means operational. The panel or panels may be held in the closed position by any means which will self-release upon the exertion of a requisite pressure differential between the inside and outside of the panel or panels, effectively relieving the pressure differential. One such effective self-releasing closure means is a hook and pile patch arrangement.

Abstract: A method and apparatus is shown for programming near perfect accuracy for ch shot in a rapid burst machine gun sequence which heretofore was not known to be attainable. Because of vibrations from many sources in the barrel, which are predictable and repeatable, it is impossible for each shot to land directly, except for the first one before vibrations really begin. Each succeeding shot (a different path) has its own signature. In this invention, the barrel is precision bent (flexed) at each instance of the sequence, to compensate for the known vibrations, as each shot travels the barrel, to get a straight shot every time.An adapter is mounted on a gun barrel near its free end. The adapter contains spaced-apart fulcrums with an actuator between the fulcrums for bending or flexing the barrel with respect to the fulcrums. This bends the barrel, causing the muzzle of the barrel to move and thus re-air the barrel independently of a mount which carries the barrel. The adapter can be used in a rapid fire weapon.

Abstract: An improved fiber reinforced penetrator rod for a kinetic energy projectile aving enhanced penetrating strength is disclosed herein. Embedded in a matrix medium of depleted uranium, or liquid phase sintered tungsten, are long fibers of tungsten-hafnium-carbide which are knitted into a continuous weave over the entire length of the fibers. This prevents splaying open or splitting of the front end of the fibers, and hence of the whole penetrator rod front end, upon impact, penetration, and receiving of the compressive forces upon hitting an armor target.

Abstract: These electromagnetic guns or launchers comprise a pair of switching rails ith a slidable switching armature associated therewith for commutating a high direct current into a pair of projectile rails which are arranged in tandem with the switching rails and are electrically connected thereto. The kinetic energy of the switching armature is transferred to the projectile armature assembly so that the projectile armature assembly has an initial velocity as the current is commutated to the projectile rails. The projectile armature assembly may be mounted on and carried by the switching armature during its entire travel or the switching armature may bump the projectile armature assembly into the conductive breech region of the projectile rails at the end of its travel.

Abstract: There is disclosed a release assembly mounted within a housing member for intaining an antenna assembly under spring deployment compression in a terminal delivery vehicle for delivery by a projectile and wherein the release assembly is comprised of a cover member and a weight member under compressive spring forces to maintain a locking ring spring within a groove of the housing member and wherein upon impact of the TDV the inertia of the weight member against the cover member causes the locking ring spring to be withdrawn from within the groove in the housing member thereby to free the release member from the housing member and thereby permitting activation of the deployment compressive spring forces for deploying the antenna assembly from the terminal delivery vehicle.

Abstract: A method or technique of resolving multiple energy sources from signals oined by a spatial array of sensors in which portions of two prior art techniques are combined to yield an improved hybrid technique.
