- Abstract
- An intermittent sprocket pulldown with accelerated geneva drive has its own directly connected synchronous motor. The remaining sprockets and shutter are driven by a second synchronous motor. The two systems, engaged temporarily for starting, run mechanically independent to eliminate shock forces and obtain an inherently flutter-free sound drive. New optics throughout give high picture and sound resolution. Tungsten and arc light sources are provided. Other features include a high-quality amplifier, independently driven accessories, turret accommodation for instantaneous lamp replacement, improved base-up mounting of lamp and improved floor mounting.
