Publication number: 20240157185Abstract: A forest fire retardant composition contains a retardant compound that includes a halide salt, a non-halide salt, a metal oxide, a metal hydroxide, or combinations thereof. The forest fire retardant composition may include at least one anhydrous salt and at least one hydrate salt. 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 dry concentrate, a liquid concentrate, or a final diluted product.

Patent number: 5148173Abstract: 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.Type: GrantFiled: April 15, 1991Date of Patent: September 15, 1992Assignee: The United States of America as represented by the Secretary of the ArmyInventors: William G. Rouse, Connie S. Kilgore, Ronald E. Rhea, Michael J. Burnham, Benjamin G. Wachob

Patent number: H769Abstract: 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.Type: GrantFiled: August 3, 1989Date of Patent: April 3, 1990Assignee: The United States of America as represented by the Secretary of the ArmyInventors: William G. Rouse, Michael J. Burnham, Erica R. Riley, Janon F. Embury, Robert H. Frickel
