Abstract

La presente invención es un aparato para sintonizar o alterar el efecto limitador del potencial de la carga que una rejilla de escorotrón (lámina dentada cargada eléctricamente) tiene sobre una superficie receptora de la carga, adyacente. El aparato para la carga de escorotrón utiliza medios productores de efecto corona, espaciados arriba de la superficie para la retención de la carga, para emitir iones de efecto corona en respuesta a un potencial de voltaje elevado aplicado a la misma, y una rejilla flexible, suspendida entre los medios productores de la descarga luminosa o efecto corona, y la superficie para la retención de la carga, en un modo no planear, de tal modo que el espaciado entre la rejilla y la superficie para la retención de la carga, sea variable a lo largo de al menos una región de la rejilla.
