Abstract

A.PROCEDE POUR LA MISE A FEU DE L'EXPLOSIF DANS DES INSTALLATIONS DE FORMAGE PAR EXPLOSION. B.PROCEDE CARACTERISE EN CE QUE L'ON MET EN PLACE LA CHARGE EXPLOSIVE SANS DETONATEUR, DANS L'ESPACE CREUX PREFACONNE DANS L'AGENT DE TRANSMISSION DE LA PIECE, ON LA RECOUVRE AU-DESSUS AVEC UNE MASSE QUI SERA VAINCUE FACILEMENT PAR UN RAYON LASER, ET ON ASSURE LA MISE A FEU AU MOYEN D'UN RAYON LASER PRODUIT PAR UN APPAREIL LASER, PROTEGE PAR UNE CHAMBRE D'EXPANSION PRATIQUEE DANS LA PARTIE DE LA MATRICE. C.L'INVENTION S'APPLIQUE NOTAMMENT AU FORMAGE DES CORPS CREUX.
