In the 100-words-per-minute teletypewriters, the permutation code equivalent of the character to be transmitted or received was at some point “set up” mechanically by positioning levers or vanes. The inertial properties of these mechanical parts placed low-level limitations on the operating set-up speed. By using the binary code and electronic switching circuits, the set-up time has been reduced from milliseconds to microseconds, making higher speeds more easily obtainable. Also, electronic approaches to printing on page or tape have contributed to the speed-up of telegraph receiving devices. Now, both tape and page devices are available at operating speeds up to 10,000 words per minute. Thanks to the Bell System, also, is the development of Data-Phone service, started in 1958. Data-Phone makes use of all the telephone switching devices and repeating apparatus so that any type of communicating system using frequencies within the voice range may be used. For such systems the telephone company will install equipment to separate the different types of electrical transmission to prevent interference. Because Data-Phone enables not only the sound of the human voice to be sent over a telephone circuit, but information from a teletypewriter or business machine as well, this new use for the telephone system has expanded its service to many types of business communications. At this writing, the Bell System advertises, “Data-Phone ‘talks’ 16 times faster than people talk. It can send punched card or taped data anywhere—at speeds up to 2500 words per minute.” While these advances have been taking place, the transistor and its companions have made a similar impact in the field of data processing. The rapid evolution of computers and other high-speed switching devices has generated a need for higher speed equipment to supply input and output requirements. The changeover to electronics has realized minification, lighter weight, reduction of mechanical parts with a corresponding reduction in maintenance, quieter operation, and greater adaptability to code and language conversion. KLEINSCHMIDT DIVISION OF SCM CORPORATION At the Kleinschmidt Division where Mr. Emilio J. Cadamagnani, Executive Vice President, is in charge, their engineering department, under the supervision of Mr. Robert L. Kearney, is keeping up with the change from electromechanically- to electronically-controlled devices. Their new Model 311 Electronic Data Printer shown here is an example. Operating at speeds from 60 to 400 words per minute and capable of receiving 5-, 6-, 7-, or 8-level code information in either serial or parallel form, it is designed for use in high-speed communications or data processing systems. Also illustrated is still another new Kleinschmidt device, the Model 321 Automatic Data Set, which includes not only a page printer with keyboard but a tape perforator and a tape reader, all compactly mounted in a console.
