Abstract: A high voltage is developed by conveying electrostatic charges to a high-voltage electrode, by means of an endless conveyor chain comprising conductive links alternating with insulating links. The conductive links comprise cylindrical pellets with cylindrical openings extending axially therein. The insulating links have enlarged spherically rounded end portions swingably received in the cylindrical openings. Pivot pins extend between the enlarged end portions and the cylindrical pellets. The conveyor is trained around wheels having spring contactors thereon for transferring charges to and from the pellets. Channel-shaped induction electrodes are positioned opposite the conveyor where it makes and breaks contact with the wheels. Operating voltages for some of the induction electrodes are obtained by idler pulleys contacting the conveyor. Each idler pulley preferably has one or more spring contactors thereon for engaging the pellets. Additional induction electrodes are preferably provided opposite the idler pulleys.
