Abstract

L'INVENTION CONCERNE LES BOBINES PREVUES POUR ASSURER LA DEVIATION DES FAISCEAUX ELECTRONIQUES ENGENDRES DANS LES TUBES A RAYONS CATHODIQUES NOTAMMENT UTILISES DANS LES RECEPTEURS DE TELEVISION. SUIVANT L'INVENTION, LES PARTIES ACTIVES DE LA BOBINE SONT CONSTITUEES DE PLUSIEURS SECTEURS OU LE COURANT CIRCULE EN SENS RESPECTIVEMENT OPPOSES DE FACON QUE LA DENSITE ELECTRIQUE CHANGE DE SIGNE ALORS QUE LA DENSITE PHYSIQUE RESTE POSITIVE OU NULLE. SUR LA FIGURE, QUI REPRESENTE L'APPLICATION DE L'INVENTION A UNE BOBINE DE FORME TORIQUE, LA COURONNE EN MATIERE PLASTIQUE DISPOSEE A L'UNE AU MOINS DES EXTREMITES DU NOYAU DE FERRITE, SUR LAQUELLE LE FIL PREND APPUI SELON UNE DISTRIBUTION ANGULAIRE DETERMINEE A L'AIDE D'ENCOCHES, EST POURVUE D'ERGOTS 5, VENUS DE MOULAGE, SUR LESQUELS LE FIL CONSTITUTIF DES SECTEURS BOBINES PREND APPUI, DE MANIERE QUE LESDITS SECTEURS SOIENT DISPOSES DANS LES SENS OPPOSES REQUIS SANS AFFECTER LES PARTIES DEJA BOBINEES.THE INVENTION CONCERNS COILS PROVIDED TO ENSURE THE DEVIATION OF ELECTRONIC BEAMS GENERATED IN CATHODIC RADIUS TUBES ESPECIALLY USED IN TELEVISION RECEIVERS. FOLLOWING THE INVENTION, THE ACTIVE PARTS OF THE COIL ARE CONSTITUTED OF SEVERAL SECTORS WHERE THE CURRENT FLOWS IN RESPECTIVELY OPPOSED DIRECTIONS SO THAT THE ELECTRIC DENSITY CHANGES IN SIGN WHILE THE PHYSICAL DENSITY REMAINS POSITIVE OR ZERO. IN THE FIGURE, WHICH REPRESENTS THE APPLICATION OF THE INVENTION TO A TORIC-SHAPED COIL, THE PLASTIC CROWN ARRANGED AT AT LEAST ONE OF THE ENDS OF THE FERRITE CORE, ON WHICH THE WIRE TAKES SUPPORT ACCORDING TO A DETERMINED ANGULAR DISTRIBUTION WITH THE HELP OF NOTCHES, IS PROVIDED WITH ERGOTS 5, COME FROM MOLDING, ON WHICH THE CONSTITUTIVE WIRE OF THE COIL SECTORS TAKES SUPPORT, SO THAT THE SAID SECTORS ARE ARRANGED IN THE REQUIRED OPPOSITE DIRECTIONS WITHOUT AFFECTING THE PARTS ALREADY COILED.
