Abstract
An expansive smoke configuration can be produced manually or automatically by the rapid, repeated discharge of smoke-forming liquid jets. A suitable device consists essentially of one or several movable tubes, each equipped with a nozzle, in conjunction with cartridges occupying the entire tube volume and having a liquid chamber and a propellant charge chamber. In case of two-component smokes, cartridges filled respectively with the two components (N1, N2) are fired in alternation. The device lends itself very well to automatic operation.
