SIGNAL LIGHT SOUND DEVICE Russian patent published in 2017 - IPC F42B12/36 

FIELD: physics.

SUBSTANCE: device contains a primer-igniter, a coaxial striker of the impact mechanism fixed in a throttling sleeve mounted on the mounting cross member. Under this cross member, a sound block of pyrotechnic equipment, adjoining both ends to the receivers, and a light block of a set of pyrotechnic channel stars are successively placed in a common tubular thin-walled casing. These stars are equipped with an explosive charge in the form of heat-sensitive interlayers. The heat-sensitive interlayers of the knock-out charge of the light block are made of smoke gun powder, and its pyrotechnic channel stars are directly connected. The throttling sleeve is geometrically closed by means of a threaded nut on the mounting cross member, which is supported by the lid of the sound block through the locking ring, which forms a locking connection with the coaxial corrugation of the casing. This block is equipped with an annular diaphragm of heat-sensitive composition. The ratio of the height of a thin-walled tubular body from the open end to the sound block, inclusive, to its diameter is, at least, one and a half.

EFFECT: increasing the functionality of the device by providing a light, one-dimensional volumetric signal that is clearly visible and distinguishable at a distance of up to 300 m, and a sound signal with the acoustic effect of a sharp jerky sound, audible over a long distance.
