Abstract
L'INVENTION CONCERNE UN DISPOSITIF D'ALERTE PYROTECHNIQUE SENSIBLE A LA TEMPERATURE. UNE GRIFFE 10 PERMET DE FIXER LE DISPOSITIF SUR LA TETE D'UNE ELECTRODE. CETTE GRIFFE VIENT DE SON COTE SE FIXER SUR UN CORPS 20, QUI LOGE UN PERCUTEUR 23 MOBILE A L'ENCONTRE D'UN RESSORT 26, ET DONT LA QUEUE 22 EST MAINTENUE EN POSITION D'ARMEMENT PAR UNE GOUPILLE FUSIBLE 27 QUI COMMUNIQUE THERMIQUEMENT AVEC LA BASE DU CORPS 20, POUR VENIR AU CONTACT DE L'ELECTRODE. UNE TEMPERATURE EXCESSIVE FAIT FONDRE LA GOUPILLE, CE QUI LIBERE LE PERCUTEUR, QUI VIENT FRAPPER UNE AMORCE ETANCHE 33, LAQUELLE INITIE UNE CANNE D'ALLUMAGE 35, QUI A SON TOUR VIENT COMMUNIQUER LE FEU A UNE RONDELLE D'AMORCAGE 36, PUIS A UNE COMPOSITION PYROTECHNIQUE 37 QUI EST AVANTAGEUSEMENT DU TYPE FUMIGENE. LA FUMEE ENGENDREE SORT PAR UN ORIFICE 40 APRES AVOIR CREVE UN PAILLET D'ETANCHEITE 41. APPLICATION NOTAMMENT A LA SURVEILLANCE DES BAINS DE TRAITEMENT PAR ELECTROLYSE.
