METHOD OF CREATING PYROTECHNIC EFFECTS Russian patent published in 1999 - IPC

FIELD: pyrotechnics. SUBSTANCE: invention relates to pyrotechnic effects for use in play situations and for audio and light signal injections, etc. For that, inflammable gas compositions (mixtures of gas oxidants with reducing gases within inflammation proportion region) and gaseous air-ignition compositions (reducing gases) are used in the form of closed gas volumes confined with surfactant-containing liquid film and have appearance of foam or individual gas bubbles. When igniting above- mentioned compositions from reaction-initiation source, composition burst or burn to give pyrotechnic effects. EFFECT: enabled ignition of pyrotechnic compositions from low-intensity ignitors not bound to them. 5 cl, 7 ex
