Abstract: Up to now exceedingly precise manufacturing tolerances had to be observed in securing or mounting a flare composition or incandescent charge sleeve in a blind borehole in the tail portion of a projectile body to ensure reliable sealing against propellant gases. To prevent this disadvantage a bolt member or plug is inserted into the blind borehole of the projectile body until the face or end surface of this bolt member or plug abuts the bottom region or portion of the blind borehole. The bolt member or plug and the projectile body are rotated relative to one another. Due to friction between the end surface of the bolt member or plug and the bottom portion of the blind borehole sufficient heat is generated at the front end of the bolt member or plug such that material of this front end of the bolt member or plug flows into an annular groove of the blind borehole to form a flange member. This flange member securely anchors the bolt member or plug in the blind borehole.

Abstract: A weapon for use in simulated war games, such weapon being particularly usable in situations where targets or opposing pesonnel are out of a direct line of sight or where weapon use in a conventional manner would be otherwise dangerous and should be avoided. Such weapon includes a frangible chamber and a slurry contained within such chamber. The slurry contains a dispersing agent and a plurality of particles serving as a marking agent. Further, a storage container is provided for receiving the slurry-containing frangible chamber to protect the chamber from accidental rupture. In use, the slurry-containing chamber is removed from the container and delivered toward the target by being manually tossed in an arcuate path to strike a target or the vicinity thereof. On striking such target, or its vicinity, the frangible chamber ruptures and the dispersing agent disperses the marking particles against such target thereby identifying the target as being eliminated from the game.

Abstract: An improvement is disclosed in the method of initiating an explosive charge arried to a target site by a rocket launched toward a target whereupon striking a soft target the performance functioning of a percussion primer to a spotting charge is improved by an impactor-cap device in communication with the percussion primer whereby the impactor will indent the primer with sufficient energy and depth to cause functioning. The impactor-cap device is comprised of a cap portion and an impactor portion. The cap portion is in the form of a thin plastic cup of a material selected from polyethylene, nylon, mylar, or cellulose acetate. The impactor portion is in the form of a ball or spike of hard material such as a steel ball, glass ball, or high impact strength plastic such as polycarbonate, methyl methacrylate (Plexiglas), or nylon.

Abstract: This invention relates to a washable marking fluid to be used in projectiles in which the prime and critical ingredient is a nonionic polyoxyethylene derivative of fatty acid partial esters of sorbitol anhydride. Projectiles produced from soft gelatin capsules containing such washable marking fluid possess ideal rheological properties and desired uniformity and stability. The fluid when packaged in a soft gelatin capsule produces projectiles that are more accurate and stable and make bright, highly visible marks that can be easily washed out with water and/or detergent and thus are ideally suitable for use in sports and games exercises.

The shaped slugs are then inserted into the interior cavities of shaped metallic jackets and are secured therein by crimping. The pyrotechnic column is formed of zirconium powder, potassium perchlorate and a suitable binder. The ratio of the length of the column to its diameter is between five and two hundred and the diameter of the pyrotechnic column is between 0.025 inches and 0.035 inches.

Abstract: In ammunition, preferably for machine cannons, including a subcaliber stabilized projectile equipped with a body of tracer material and a stabilizing element, the heat released during combustion of the tracer material is utilized to drastically change the strength of the material of an element used to fasten the stabilizing element to the projectile. By being able to set the time of combustion and of the change in the material, the stabilizing element changes its position with respect to the projectile. The system or ammunition in question becomes unstable and drops to the ground.

Abstract: A system for identifying a hard target from a distance. A delivery vehicle, such as a missile or bomb, is adapted to be dropped from the air. The delivery vehicle contains a plurality of hard target identifier or kinetic penetrator elements. Each of the elements has a nose portion of aerodynamic shape and a plurality of fins connected thereto.

A soft surrounding area, such as earth or water will absorb the elements. The elements may be passive for reflecting waves, such as acoustic waves or electromagnetic energy. Alternatively, they may be active elements capable of ejecting a dye, such as a fluorescent dye, or for transmitting acoustical or electromagnetic energy upon being activated.
