Patent DE-3908672-A1 (DE)
Title: Method and device for film exposure
Inventor: SHARPE ROD P
IPC: G03B19/18
Filed: 1989-03-16
Abstract: A method and a device are described for filming normal and wide-screen images with one and the same camera, using 35 mm film. In this method, a 35 mm film is guided past an aperture of wide-screen format, parallel to the longitudinal axis of the aperture. The device is a camera having the necessary mechanisms to cause the film to move in the required direction at the required speed. The camera contains a film transport and drive mechanism having 24-toothed pinions on opposing sides of the aperture for advancing the film by a selected number of perforations per image, which keep the film under uniform control at any time. The camera furthermore contains a film-aligning arrangement, in which aligning pins are pushed into mutually opposing perforations in the film, which are in close vicinity to the aperture. The film-aligning arrangement also presses a pressure plate against the film in such a manner that the film is held in its position at the aperture. The aligning pins and the pressure plate keep the film in good alignment as long as the diaphragm is open. An aperture plate arrangement contains a replaceable aperture plate so that the aperture size can be changed as desired.

Title: Process for producing low-alcohol beverages having yeast aroma
Inventor: SCHUR FRITZ DR
IPC: C12C12/04
Filed: 1989-05-12
Abstract: The present invention relates to a process for producing low-alcohol beverages having yeast aroma using a yeast-fermentable substrate liquid containing nutrient and/or flavour substances and a yeast taken from a fermentation process. To decrease the formation of alcohol, the yeast cells are mechanically disintegrated. The complete cell digest or a fraction thereof is brought into contact with the substrate liquid. Finished wort serves as substrate liquid for the production of low-alcohol beer, and fruit juice or grape juice serves as substrate liquid for the production of low-alcohol fruit wine or wine, respectively. The process according to the invention can be carried out at a temperature above 5@C. When 100%-disintegrated yeast cells are used, alcohol formation is prevented completely.

Patent DE-4008201-A1 (DE)
Inventor: SUESSMEIER GEORG DIPL ING
IPC: H04J1/04
Filed: 1990-03-15
Abstract: To process several television signals for transmission purposes, for example for an optical waveguide cable television distribution network, the television signals are first individually digitised (AD) and in each case digitally converted into various non-overlapping frequency bands (DFU1...DFU8). The television signals thus converted are then combined by means of a logical adding stage (ADD) to form one frequency-division multiplex signal. Due to this processing, the complexity at the receiver end can be kept down. Only one D/A converter (DAG) and one channel group converter (UG') is necessary for a group of channels of television signals. <IMAGE>
