Abstract

1,156,742. Changing sign. DATEL Ltd. 2 Jan., 1967 [6 Jan., 1966], No. 625/66. Heading G5C. [Also in Division H1] A digital display unit geared to a rotary switch (see Division H1) for use as a position indicator, comprises a pair of side-by-side reversible film transport mechanisms, the films being fed over a lamp housing 7 by sprockets 6. The ends of each film are held in bobbins by U-shaped springs 8, the bobbins being geared together at 2, 3. An indexing mechanism comprises spring- loaded balls 13, Fig. 2, engaging nylon detent drums 12.
