Abstract
The operation of a conventional Geneva-type intermittent mechanism is analyzed and used as a basis for developing several thoughts which may lead to a reduction of pull-down time. Reduction of pull-down time is desirable in that it permits the use of shutter blades of smaller width, thus either increasing the screen brightness or permitting the same screen brightness with less power in the lamp. The increase in the acceleration of the film due to the reduction in the pull-down time naturally will increase the wear and damage to the film. Means are shown, however, whereby the pull-down time may be reduced without subjecting the film to any greater acceleration than occurs with the conventional Geneva-type intermittent mechanism and consequently will not increase the wear on the film.
