<p>Apparatus for dispersing a fluent material such as a liquid includes a device (10) for discharging a stream of the fluent material and a device (41) for providing energetic electrons such that the electrons impinge on the fluent material to provide a net negative charge on the fluent material in the discharged stream. The fluent material discharged is dispersed at least partially under the influence of the net negative charge so imparted. The electron-supply device (41) includes a chamber (44) separated from the fluid passageway (20) by an electron-permeable membrane (40) and may also include an electron gun (42) for generating a beam (68) of energetic electrons such that the electron beam passes through the window and impinges on the fluent material. The electrons may impinge on the fluent material as the fluent material is discharged from the device so that the fluid flow carries the charged portions of the fluent material away from the device. The apparatus may be used to atomize liquids even where the liquids are electrically conductive.</p> |
