Title: Electronic speed control for cine camera motor - is of light weight saves space and uses marked disc rotating in front of sensor
Inventor: WINKLER ALFRED
IPC: H02P23/16
Filed: 1974-07-12
Abstract: The motor (8) whose speed is to be regulated turns (via worm 7, gear 6) a disc (18) which has magnetic (or optical) markings on its circumference. A magnetic (or optical) sensor detects the markings as they pass it, and so generates a signal whose frequency is proportional to the motor speed. This signal is amplified (17) and limited (16) before being applied to a de-tuned resonant circuit (15) which converts the fixed (limited) - amplitude signal into one whse amplitude depends on its frequency. This voltage, as rectified (14) and smoothed (13), represents the actual momentary speed of the motor. a corresponding voltage representing the target speed is set by hand (10, 11, 12) and the two are compared in a difference amplifier (9) whose output is applied directly to regulate the current drving the motor.

Title: HV terminal box for electrical machine - having pressure relief diaphragm with rupturing lines is sealed until rupture occurs
Inventor: SOCHER FRANZ
IPC: H02G15/10
Filed: 1974-10-08
Abstract: The safety of H.V. terminal boxes during internal faults may be improved by incorporating a deliberately weakened area in the box. The wall of a cast or fabricated box is cut away in one area and a thin sheet of metal spot welded in. This sheet has perforated or semiperforated lines impressed in it, but any resulting openings are sealed up by compound applied to the outside. Thus in normal operation the cable box is adequately sealed, but in the event of an internal fault a relatively modest rise in pressure inside the box ruptures the thin sheet along its weakened lines and a dangerous explosion is avoided.
