A Simplified All-Purpose Film Recording Machine
This paper describes a completely new recording machine for 16- or 35-mm film having a minimum of weight and bulk with a maximum of simplicity and excellent basic performance. A new sealed light valve is used in a simplified modulator and optical system employing a prefocused lamp for variable-density recording. A microscope is available for observing the valve in the modulator, and photocell monitoring and other accessories may be added if desired.
