Abstract
L'INVENTION CONCERNE UN DISPOSITIF POUR REGLER AUTOMATIQUEMENT LA POLARISATION DU NIVEAU D'EFFACEMENT D'UN TUBE-IMAGE DANS UN SYSTEME DE TRAITEMENT D'UN SIGNAL VIDEO, AVEC UN MOYEN POUR COUPLER LE SIGNAL AU CANON D'ELECTRONS. SELON L'INVENTION, UN MOYEN 20 APPLIQUE UNE TENSION DE POLARISATION DE REFERENCE A LA CATHODE 16 PAR UN TRAJET DE CONDUCTION 21 PENDANT UN INTERVALLE DE MESURE COINCIDANT AVEC L'EFFACEMENT; UN MOYEN 28 APPLIQUE UN SIGNAL AUXILIAIRE A LA GRILLE PENDANT UNE PARTIE DE CET INTERVALLE; UN MOYEN 22 PRODUIT UNE DIFFERENCE DE TENSION PROPORTIONNELLE A LA DIFFERENCE ENTRE LE COURANT DANS LE TRAJET 21 PENDANT LA PARTIE DE L'INTERVALLE DE MESURE EN D'AUTRES TEMPS; UN MOYEN 24 SENSIBLE A LA DIFFERENCE DE TENSION APPLIQUE UN SIGNAL DE REGLAGE AU MOYEN 21. L'INVENTION S'APPLIQUE NOTAMMENT AUX TELEVISEURS.
