Abstract :
The adaptation of facsimile scanning and recording apparatus to the handling of commercial telegrams has dictated the use of several expedients to accelerate the processing, among them being higher speed of trace and scanning rate, minimization of wasteful scanning, dry-process recording, and automatic loading and discharge. Apparatus incorporating these features is in daily use, having a capacity of 50 telegrams per hour.
