Abstract
A balanced ion emission system for "shockless type" static eliminators (wherein pointed discharge electrodes are capacitively coupled to one side of an A.C. high voltage source) employs pointed needles which are adjacently spaced from at least some of the pointed discharge electrodes and connected by way of a conductive path to the other side of the A.C. high voltage source. The points of the needles are adapted to be adjustably positioned with respect to the discharge electrodes so that an equal number of ions of each polarity are discharged into the atmosphere for impingement upon the articles to be neutralized.
