AIR IONIZER Russian patent published in 1997 - IPC

FIELD: electronic engineering. SUBSTANCE: air ionizer has electrode mounted on holder for rotating about its axis and provided with electron-emitting members placed at certain distance from mentioned axis and fixed on electrode so that torque is produced during emission of electrons; electrode is connected to controlled high-voltage supply; newly introduced are series-connected speed sensor, speed meter, and control unit whose output is connected to input of high-voltage supply. Speed sensor input is coupled with electrode or its holder. EFFECT: improved design. 2 dwg
