Abstract
L'INVENTION CONCERNE LA TRANSMISSION D'INFORMATIONS. ELLE A POUR OBJET UN PROCEDE ET UN AGENCEMENT DE TRANSMISSION ENTRE UNE CAGE D'EXTRACTION 1 ET LA SURFACE DU SOL. UN EMETTEUR-RECEPTEUR 5 EST RELIE INDUCTIVEMENT A UN EMETTEUR-RECEPTEUR 6 PAR DEUX TRANSFORMATEURS 9, 10 COUPLES PAR UN CIRCUIT COMMUN FORME PAR LE CABLE 4 DE LA CAGE 1 ET LA CAPACITE 13 DE CETTE DERNIERE A LA TERRE. LA FREQUENCE PORTEUSE EST DE L'ORDRE DE 30 A 100 KHZ; ELLE EST CHOISIE POUR QUE CE CIRCUIT PRESENTE UNE IMPEDANCE BASSE. APPLICATION A LA TRANSMISSION D'INFORMATIONS DANS LES INSTALLATIONS MINIERES.
