Abstract: A photosetting apparatus is provided having a cylindrical bed into which sheet-shaped photo-material is transported and placed against an inside thereof. The cylindrical bed has a longitudinal axis positioned in spaced relation from an inside surface of the bed and such that the cylindrical bed inside surface curves in cylindrical fashion partially around the longitudinal axis. An exposure optics exposes the sheet-shaped photo-material, the exposure optics being displaceable along the longitudinal axis of the cylindrical bed. A conveyor mechanism conveys the photo-material parallel to and in a direction along the longitudinal axis of the cylindrical bed into a position adjacent the inside surface of the bed. A guide mechanism having movable elements presses the photo-material against the inside surface of the cylindrical bed from inside.

Abstract: An incremental rotary transmitter is proposed for mounting upon the free end of a shaft. The transmitter comprises a pulse disc rigidly secured to the shaft and a relatively stationary scanning disc freely mounted on the same shaft. The scanning disc is thus subject to the same flexing oscillations or errors in true running of the shaft as the pulse disc, so that measurement errors due to eccentric movements of the pulse disc are substantially reduced.

Abstract: For the line-by-line optical scanning of a film as it passes at high speed through a scanning region, particularly to obtain television image signals, a light source directs light to a sensor. To reduce friction of the film adjacent the scanning region, two rollers or endless belts support the film at positions on the film outside the film frames. These rollers or belts replace the previously usual stationary film guide shoes adjacent the film gate. Lateral guidance of the film can be provided by rollers.
