Abstract

Método de control de células electrolíticas para la inscripción de caracteres, cuya célula comprende una serie de electrodos que presentan formas apropiadas para la inscripción de caracteres, un contraelectrodo y un electrolito, en cuyo método, para provocar la escritura sobre uno de los electrodos, se aplica a dicho electrodo una tensión negativa y para provocar el borrado una tensión positiva y en el cual, cuando ha terminado el borrado, la tensión entre dicho electrodo y el contraelectrodo tiene tendencia a crecer hacia un valor de umbral correspondiente a la producción de una reacción parásita, caracterizado porque se determina el fin de los impulsos de borrado por el instante en que la tensión electrodo-contraelectrodo crece hacia la tensión de umbral correspondiente a la producción de una reacción parásita.
