AN ELECTRIC SLEEP TREATMENT DEVICE IS ONE OF THE MANY VARIED EXHIBITS ON DISPLAY AT THE SOVIET EXHIBITIONS NOW IN PROGRESS AT LONDON'S EARL'S COURT. THE UNIT - OC-2 - IS A LOW FREQUENCY PULSE CURRENT GENERATOR, AND IT CAN BE USED FOR HOSPITAL OR DOMESTIC TREATMENT OF PATIENTS.

ELECTRIC SLEEP THERAPY HAS PROVED EFFECTIVE IN THE TREATMENT OF NEUROTIC COMPLAINTS INCLUDING DISTURBED SLEEP AND CASTRIC ULCER. IT'S MILD ACTION, DUE TO WEAK CURRENTS, HAS HAD NO ILL EFFECTS ON PATIENTS.

ANOTHER INTERESTING EXHIBIT - THE SOVIET LITHOTRITE - YPAT-1 - WHICH IS DESIGNED TO CRUSH STONES OR SECRETIONS IN THE URINARY BLADDER IS ALREADY MOST POPULAR OUTSIDE THE SOVIET UNION.
