ABSTRACT:
A static charge control device is disclosed having an electrostatic focusing arrangement. The device requires no forced air element yet enables ions, produced at separate positive and negative needle electrodes, to be separately directed outwardly to a neutralizing area for neutralization of static charges thereat. The needle electrodes are mounted on a mounting plate so that the tips of the needles extend forwardly through different apertures in the forwardly positioned electrostatic focusing plate. Positive and negative ions, produced at the needle electrodes by continuous DC voltages applied to the needle electrodes, are moved forwardly from the needle electrodes toward a neutralizing area due to repulsion forces, and are focused by the electrostatic focusing plate to establish a substantially uniformly diverging pattern, the axis of which is normal to the electrostatic focusing plate when the needle electrodes are centrally positioned within the apertures in the electrostatic focusing plate, and forms an acute angle with the electrostatic focusing plate when the needle electrodes are offset with respect to the centers of the apertures.
