Abstract
UNA DISPOSICION (14) ANODO-CATODO DE NUEVA CONFIGURACION PARA LA ELECTROEXTRACCION DE ALUMINIO DE ALUMINA DISUELTA EN SALES FUNDIDAS, QUE SE COMPONE DE UNA UNIDAD DE JUNTA DE ELECTRODO DE DOBLE POLARIDAD ANODO-CATODO, O UNA JUNTA DE DOBLE POLARIDAD CONTINUA, EN LA QUE EL ANODO (16) Y CATODO (18) ESTAN LIGADOS JUNTOS Y SU DISCONTINUIDAD INTERELECTRODICA ES MANTENIDA SUSTANCIALMENTE CONSTANTE POR MEDIO DE CONEXIONES (15) HECHAS DE MATERIALES DE ELEVADA RESISTENCIA ELECTRICA, QUIMICA Y MECANICA. NUEVAS CUBAS MULTI-DOBLE-POLARIDAD PARA LA ELECTROEXTRACCION DE ALUMINIO CONTIENEN DOS O MAS DE TALES UNIDADES (14) DE JUNTA DE ELECTRODO DE DOBLE POLARIDAD ANODO-CATODO. ESTA DISPOSICION PERMITE LA ELIMINACION DE CUALQUIERA DE LAS UNIDADES DE JUNTA DE ELECTRODO DE DOBLE POLARIDAD ANODO-CATODO DURANTE LA OPERACION DE LA CUBA MULTI-DOBLE-POLARIDAD CUALQUIERA QUE SEA EL ANODO Y, O EL CATODO, O CUALQUIER PARTE DE LA UNIDAD DE ELECTRODO QUE NECESITE REACONDICIONAMIENTO PARA OPERACION EFICIENTE DE LA CUBA,Y ENTONCES RESUMERGIRLA DENTRO DE LA CUBA PARA QUE CONTINUE LA OPERACION NORMAL.
