Abstract
There is disclosed a process for the generation of a dense cloud, as for the purpose of camouflage. Finely divided solid particles are discharged for a container, as by means of compressed gas, the solid particles being in the form of a microfine powder having a particle diameter of up to 60 .mu.m and being impenetrable to visible light and infra-red light of up to 14 .mu.m wave-length and having a settling velocity of up to 5 cm/sec. The powders used are talc, kaolin, calcium carbonates, magnesium carbonates, sodium hydrogen carbonates or other free-flowing powders or powders that have been rendered flowable, which form buoyant clouds upon being dispersed as by atomization.
