Title: Sound cine camera with mixing facilities - has recording head latched out of operation with cam and rotating lever and biasing spring
Inventor: BODE KURT
IPC: G03B31/00
Filed: 1975-09-06
Abstract: The sound film camera has special facilities for mixing-shots, slot-motion and speeded-up photography. The double exposure required for mixing-shots and the abnormal film speeds used for the others, render simultaneous sound-recording impracticable. The recording head is therefore put out of use and its associated motor stopped. These changes are made automatically, as soon as the photographer selects one of the special facilities. A cam is used to control the position of the first of three levers, whose third member engages or releases a latch. The engaged latch prevents a spring from raising the shutter-release-operated lever, which would bring the film drive and the recording head to the operating position. At the same time, the film drive motor is switched off.
Patent DE-2540774-A1 (DE)
Title: Seawater distillation by vertical tube evaporator - with feed and blowdown at opposite horizontal ends and water recycling
Inventor: POTTHARST JUN JOHN E
IPC: B01D1/28
Filed: 1975-09-12
Abstract: The heat exchanger has a horizontally extending array of liquid tubes within a vapour jacket. The lower ends of the tubes receive water from a manifold which receives feed sea water at one horizontal end. The water rises in the tubes when it is heated by the vapour and bubbles over at the top end into a manifold from which the water is recirculated to the lower manifold. Vapour removed from the upper manifold is compressed and supplied to the jacket of the heat exchanger. Blowdown is taken from the lower manifold at the opposite end to the feed end. By employing a wide horizontally extending array of heat exchanger tubes and attaching the feed and blowdown tubes at opposite ends a gradient of salt concentration is established in the lower manifold. This allows a higher temperature difference between the vapour and boiling point of the brine to be maintained near the inlet end of the heat exchanger. Thus a higher efficiency is achieved.

Title: Correction circuit to prevent baseband IF modulation distortion - removes differential phase or gain distortion in FM radio channels
Inventor: BARANYI ANDRAS
IPC: H04B14/00
Filed: 1975-10-03
Abstract: The connection circuit is used to reduce baseband IF modulation distortion. The distortion arises from differential phase distortion and dynamic differential gain distortion in radio channels in FM systems. A static IF modulation spectrum of order n is produced from the baseband signal using a circuit with non-linear characteristics of order n+1. The resulting spectrum is differentiated once and/or twice and then added to the baseband signal spectrum. Distortion of the baseband IF modulation spectrum due to differential phase and/or gain (order n) distortion is prevented by controlling the level of the converted spectrum. The differentiating systems (D1) and (D2) are used.
