Title: Generator apparent power limiter - has amplifier delivering voltage dependent on current to voltage comparator preceding voltage regulator
IPC: H02P9/26
Filed: 1971-06-12
Abstract: The limiter restricts the apparent power produced by a generator using a regulator that applies a counteracting additional reference to the generator's control loop when the load current exceeds a given value. The regulator(1) is an amplifier whose output is the additional reference voltage which is passed to a comparator receiving the actual voltage with the main reference voltage. This comparator controls the generator's voltage regulator(2). The amplifier's output is fed back via a resistor(4) to its input-side comparator to relate voltage drop to current increase.

Abstract: To improve the reproduction of a video image, particularly for avoiding edge flicker, line flicker, line crawl or large-area flickering, different methods are known in which it is necessary to switch between individual methods as a function of movements. To avoid switching between different methods as a function of movement, a progressively recorded frame is divided into two fields, the second field being formed from the arithmetic mean between the current lines and the preceding lines and these two fields are reproduced at twice the frame repetition rate as the original frame. The invention is applied in image reproduction devices.
