Abstract: DYNAMIC REMOVAL OF SOLID IMPURITIES FROM RECIRCULATING INK In an ink jet printer solid impurities contaminating recirculating ink are removed by subjecting contaminated ink to ultrasonic energy for forming an aerosol of the ink. The aerosol of ink is entrained in an air stream and carried to impactor means where the ink aerosol is caused to return to a liquid state.

Abstract: HIGH FREQUENCY ALTERNATING FIELD CHARGING OF AEROSOLS Apparatus for high frequency alternating electric field charging of aerosol particles in the form of an ink mist which may subsequently be used for ink mist printing. A charging electrode excited by a high frequency alternating voltage source is used to produce a charging field. The charging field produced by the high frequency A.C. voltage is maintained at a predetermined frequency to avoid attracting the charged particles to the charging electrode, thereby avoiding precipitation on this electrode and allowing substantially higher voltages to be applied to the charging electrode.
