A Binary Outscriber using Facsimile Paper

In summary, there has been described an Outscriber which, using a modified Western Union 3-stylus Teledeltos recorder in conjunction with the required accessory electronic and mechanical equipment, is capable of printing, in a binary presentation, 80,000 bits per minute. The record is in the form of two 40-bit words per line, and 1000 lines per minute. Each line of data may, if desired, be reprinted up to 8 consecutive times in order to give immunity against statistical fluctuations in the paper characteristics and in the operation of the device. A record containing 1,024 words, where each of the 512 lines has been printed one time, is included on a piece of Teledeltos paper 8-1/4´´ by 19´´. After there is deducted from this area of paper the 1-5/8´´ of width for the edge and center margins, the figure of merit for this device is found to be 320 bits per square inch per unit time.
