Claims
- 1. In an improved method of screening against visual light transmission, the improvement comprising injecting into the atmosphere a screening cloud of fine particles comprised of titanium dioxide composition, in which the particles are coated and of submicron diameter, said cloud being formed by bursting a compacted generally cohesive solid mass of said particles in the atmosphere to there aerosolize and disperse said particles in the atmosphere.
- 2. The method according to claim 1, in which said particles are formed of a titanium dioxide compound.
- 3. The method according to claim 1, in which said particles are coated with siloxane to retain their individual identity.
- 4. The method according to claim 3, in which said particles are generally of a size of between about 0.2-0.5 microns in diameter.
- 5. The method according to claim 4, in which said particles are generally spherical in size and shape.
- 6. The method according to claim 1, in which said bursting is effected by bursting an HE explosive charge within said compacted cohesive mass of titanium dioxide powder.
- 7. The method according to claim 6, the ratio of the weights of said compacted cohesive mass of particles relative to said HE explosive charge being within the range of approximately 15:1-30:1.
- 8. The method according to claim 7, wherein the screening cloud is minimally hazardous to people, animals and the environment.
