Abstract (en)
[origin: EP0055984A2] The maximum subcorona potential level to which a particular conductive bristle brush is able to regulate an electrostatic charge on charge-retaining material is substantially increased by limiting the electrical current available to said particular conductive bristle brush from a potential source coupled to said brush to a level that is less than a magnitude necessary for corona generation.
