Abstract: A forest fire retardant composition contains water and a retardant compound that includes a halide salt, a non-halide salt, a metal oxide, a metal hydroxide, or combinations thereof. The halide salt may be magnesium chloride, calcium chloride, or both. The magnesium chloride hydrate has a formula MgCl2(H2O)x, wherein x is at least one of x=1, 2, 4, 6, 8, or 12. The calcium chloride hydrate has a formula CaCl2)(H2O)x, wherein x is at least one of 1, 2, 4, or 6. The composition may be in the form of a liquid concentrate or a final diluted product. The final diluted product is effective in suppressing, retarding, and controlling forest fires while exhibiting corrosion resistance and low toxicity.

Abstract: A millimeter wave screening cloud is formed comprised of an aerosol of fine ibers of a carbon composition, in which the particles are of micron diameter and millimeter length. The cloud is formed by aerosolizing a compact mass of carbon composition fibers through the action of explosively bursting such compact mass in the atmosphere at the desired cloud location.

Abstract: A minimum hazard visual screening cloud is formed comprised of an aerosol fine spheres of a titanium dioxide composition, in which the particles are of submicron diameter. The cloud is formed by aerosolizing a compact mass of titanium dioxide spheres of submicron diameter through the action of explosively bursting such compact mass in the atmosphere at the desired cloud location.

Abstract: A minimum hazard visual screening cloud-forming product is made by forming slurry of fine spheres of titanium dioxide composition, of submicron diameter, together with a volatile surface-wetting agent liquid, in the form of a liquid hydrocarbon, extruding and severing the extended slurry mass into a desired container shape, in particular, a hollow cylindrical shape, and drying the mass. An HE explosive mass is inserted into the resulting compacted hollow cylinder, enabling bursting of the compacted mass.

Abstract: A smoke grenade system for use on an armored vehicle. This system includes vehicle having a body and a turret, launching tubes mounted on the two sides of the turret, a first switch for expelling a first salvo of smoke grenades and a second switch for expelling a second salvo of smoke grenades. Each switch actuates one-half of the launching tubes on one side of the vehicle plus one-half of the launching tubes on the other side of the vehicle.

Abstract: This invention provides a method used for radiographic inspection of matel within a container, where the container is a dense material and the contents to be radiographically inspected are of a less dense material.

Abstract: An obscurant apparatus for use in forming a smoke screen. This apparatus ludes a hopper having a space for fluidizing a selective powder, an inlet jet nozzle extending through the hopper into the space, an outlet passage extending through the hopper and surrounding the inlet jet nozzle, spray means connecting to the outlet passage, and a compressed air source connecting to the jet nozzle.

Abstract: A minimum hazard visual screening cloud is formed by vaporizing diesel fuel nside a vehicle exhaust manifold pipe which, upon entering the ambient atmosphere, condenses into an aerosol comprised of small droplets, thereby producing a large sustaining cloud which obscures both the vehicle and the adjacent downwind areas.
