Abstract
1349858 Cinematography; automatic control of position EASTMAN KODAK CO 19 April 1971 [6 Feb 19701 21020/71 Headings G2E and G3R Apparatus for advancing a cine film includes a control device able to advance a motor according to a given pattern, e.g. on pulse of shape A, see Fig. 2. This should advance the film by one frame length. Any deviation is sensed by a detector 94 which modifies the pattern, e.g. pulses B or C, so that the subsequent film advance brings the film back into position. The control device may be of the form shown in Fig. 1. The detector 94 senses the position of film perforations 95, 96, 97. The clock 91 provides pulses to generator 92 which are amplified and drive motor 18. When an advance of the motor is complete, delay device 90 transmits the clock output to detector 94 which then can supply details of the film advance achieved to comparator. These details are compared with a reference signal from source 102 which gives details of a correct film advance. An error signal, if any, is then emitted by comparator 101 to modify the gain of amplifier 93.
