Abstract

719,687. Electrostatic machines. FELICI, N. J. Nov. 20, 1952 [Nov. 21, 1951], No. 29338/52. Class 35 An electrostatic motor or generator has a rotating insulating charge-carrier moving between charging and discharging electrodes. In the form shown a fixed outer insulating cylinder 7 has longitudinal grooves 8 carrying oppositely disposed pairs of conducting charge inducing bars 9 and screens 10. The inner surface of the stator 7 is covered by a semi-conducting sleeve 11 in contact with the electrodes 9 and 10 to prevent excessive fleld concentration at their edges. Inside the rotary cylindrical charge carrier 20 is a further insulating stator body 12 having longitudinal grooves 14 facing the grooves 8 in the outer member and containing metal blades 15 and 16 facing the charging electrodes 9 and screens 10 respectively. The metal blades have springs 17 at each end carrying wires 18, 19 stretched between them and serving as ionizing and collecting electrodes for charges to and from the charge carrier 20. The charging electrodes 9 are connected to a separate source of potential through a conductor 26; the wire electrodes 18 are earthed through conductors 28; and the screen plates 10 and electrodes 19 are connected through a conductor 29 to the output terminal of the machine. The machine is insulated by compressed gas, e.g. hydrogen at 10-20 Kg./ sq. cm. A modified form is described in which the charging electrode and screen are inside the rotary charge carrier and the collector elements are situated outside it. It is stated that the conveyer may be disc-shaped.
