Total Automation for the Motion-Picture Theater

Al Boudouris, Geoffrey T. Gray, John J. Burlinson

After giving a brief history of theater automation, the design goals to be attained for a fully automated theater operation are described. Several basic solutions to the main problem are set forth and reasons for trying to run a 35mm projector in reverse are given. Research and development necessary for achieving the successful reverse operation of standard 35mm projectors is described and conclusions drawn from practical experiments are given. Not only was it established that it is possible to run 35mm projectors successfully in reverse—an operational mode essential for projector automation—but it was also found that certain modifications made for reverse operation provided for a steadier projected image when running forward, with much less film “flutter” and a minimum of film tension. Motor drive, projector control signals, operational modes and auditorium control functions which were achieved in actual theater installations, are described and illustrated.
