Appeal No. 1996-1736
Application 08/418,267
electrodes, each of the electrodes in said first and second
pairs of electrodes being diametrically oriented about the
rotational axis substantially laterally to the flow of air and
equidistantly spaced from the rotational axis of the fans and
being sufficiently spaced equidistantly apart about said
rotational axis to enable said air flow to carry at least a
portion of the positive and negative ions away from respective
ones of said first and second pairs of electrodes and out of
said housing through said outlet passage without
neutralization of the ions from ones of the first and second
pairs of electrodes by contact with other of said first and
second pairs of electrodes; and
a high voltage supply connected to the first and second
pairs of electrodes for applying high D.C. voltage of positive
polarity to each of the electrodes of the first pair of
electrodes and for applying high D.C. voltage of negative
polarity to each of the electrodes of the second pair of
electrodes to produce supplies of both positive and negative
ions in said flow of air about the respective first and second
pairs of electrodes to be carried in said air flow through
said outlet passage.
