Abstract

1436152 Light-proof gates AGFAGEVAERT AG 12 Oct 1973 [13 Oct 1972] 47665/73 Heading G2X A light-proof gate for passing photographic strip material between a light room and a dark room is built into the dividing wall 3 and comprises rollers 5, 5a at the end of levers 6, 6a. The levers have a common pivot 7, and the rollers move in an arcuate guiding channel 9, the whole arrangement of rollers and channel being light-proof. The rollers may be of electrically conductive soft rubber. Means such as springs, a pneumatic system, or a pair of permanent magnets may be used to draw the rollers against each other.
