Abstract

1. Process for the large-area application and distribution of electrically conductive liquids having a specific resistance of < 10**4 OMEGA . m, in which a high voltage is applied to the liquid, characterised in that the liquid is allowed to issue from a nozzle or capillary at such a low rate of flow that, immediately downstream of the nozzle or capillary, it forms a cohesive filament of liquid which then disintegrates into individual drops and in that, by means of the high voltage relative to earth which is applied to the filament of liquid, the drop size is stabilised and a conical distribution of drops (cone of drops) is produced whose apex angle depends on the level of the voltage.
