SANBORN OSCILLOGRAPH RECORDING SYSTEM HAVE MANY APPLICATION
Sanborn Recorders Help Speed Flight Design SPERRY GYROSCOPE COMPANY uses a two-channel Sanborn Recording System for basic research on their Zero Reader* Flight Director, a device which simplifies the manual control of aircraft. T h e Sanborn System shown above is recording the output of a flight simulator that solves Zero , Reader equations. REG.

At MCDONNELL AIRCRAFT C O R P O R A T I O N the movements of a guided missile are simulated by high-precision analog computers which in turn send eight different resultant electric signals into two Sanborn fourchannel Recording Systems (left) for the graphic recording of the hypo thetical results of the guided missile problem.
How can Sanborn help you? A t D O U G L A S AIRCRAFT C O M P A N Y ' S Flight Test Section, a Sanborn two-channel Recording System (shown removed from case for field opera tion) is used in conjunction with a tele meter radio link to record surface motion vibration in a flying aircraft while it is per forming tests requiring continual moni toring. Recorded tracings provide the necessary permanent visual time his tory for comparison of the two events recorded and a study of their individual characteristics.
