Abstract

L'INVENTION CONCERNE UN CONDENSATEUR ELECTROLYTIQUE ET UN PROCEDE POUR SA FABRICATION. DANS UN DISPOSITIF, DANS LEQUEL UNE FEUILLE D'ALUMINIUM 5 SE DEVIDE D'UN ROULEAU 4 POUR S'ENROULER SUR UN ROULEAU 6 EN TRAVERSANT DEUX CHAMBRES 7, 8, UN MAGNETRON AU TANTALE 9 ET DEUX MEMES CHAMBRES 10, 11, LA FEUILLE D'ALUMINIUM EST RECOUVERTE DE TANTALE POUR FORMER LA FEUILLE D'ANODE DU CONDENSATEUR ELECTROLYTIQUE. APPLICATION NOTAMMENT A LA FABRICATION DE CONDENSATEURS ELECTROLYTIQUES TRES RESISTANTS A LA CORROSION.THE INVENTION RELATES TO AN ELECTROLYTIC CONDENSER AND TO A PROCESS FOR ITS MANUFACTURING. IN A DEVICE, IN WHICH AN ALUMINUM SHEET 5 WOLDS FROM A ROLLER 4 TO WIND UP ON A ROLLER 6 THROUGH TWO BEDROOMS 7, 8, A MAGNETRON AT TANTALUM 9 AND TWO SAME BEDROOMS 10, 11, THE SHEET ALUMINUM IS COATED WITH TANTALUM TO FORM THE ANODE SHEET OF THE ELECTROLYTIC CAPACITOR. APPLICATION IN PARTICULAR TO THE MANUFACTURE OF ELECTROLYTIC CAPACITORS VERY RESISTANT TO CORROSION.
