Abstract
A corona discharge static neutralizing device includes a wire electrode retained in tension between spaced ends of a resilient support member that is positioned within a flowing air stream. Another electrode aligned with and spaced from the wire electrode promotes a flowing ion stream, when connected to receive an ionizing difference of potential, that flows in skew orientation relative to the flowing air stream. Multiple wire electrodes are supported in tension on a resilient support member along with another electrode disposed on the support member intermediate the wire electrodes and in substantially the same plane therewith.
