Abstract: A device for discharging positive or negative static electricity on an article by producing charge of opposite polarity at a sharp tip electrode. The pulse charge is produced by a capacitor triggered at a predetermined voltage to discharge through the primary winding of a transformer to induce a high voltage in the secondary winding which is rectified by a diode to give a pulse charge of the required polarity at the sharp tip electrode. A smoothing capacitor is connected across the output from the diode so that a consistent smoothed or semi-smoothed D.C. potential is obtained when the device is operated continuously. The device may be operated from the A.C. mains or from battery means.
