    THE ever-increasing complexity of telephone and telegraph switching circuitry in the Bell System had reached a stage about 10 years ago, where many of the conventional type of schematic circuit drawings presented difficulties in training of personnel and maintenance. It then became necessary, particularly for the more complex circuits, to prepare and maintain a separate series of drawings—e... View full abstract»

    A central control system is described which follows preset programs and automatically switches on or off up to 40 groups of remote operations—each on its own time schedule. Utilizing carrier current signals, it operates over existing electric circuits and does not require the installation of any transmission wiring. View full abstract»

    THE SOLUTION to a large number of physical problems involving such topics as heat transfer, fluid flow, electric or magnetic fields, etc., may often be found most easily by setting up the required boundaries in an electrolytic tank. This is essentially an analogue method, and the solution consists in finding the equipotential lines and tracing them on a piece of paper. View full abstract»

  • Perpendicularly superposed magnetic fields

    Publication Year: 1955, Page(s): 661
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (155 KB)

    THE CHARACTERISTICS of a ferromagnetic reactor as a function of two perpendicularly superimposed magnetic fields were discussed in an article by Beck and Kelly1 in 1948. The core and coil configuration shown in Fig. 1 illustrates one practical method for superposing two perpendicular magnetic fields. The core is a hollow toroid of ferrite material which encloses an annular coil, and whi... View full abstract»

  • Calculating servo transient response

    Publication Year: 1955, Page(s): 666
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (205 KB)

    THE methods of calculating the closed-loop frequency response of a linear control system are well known and straightforward. To calculate the transient response to a step input, which in some cases may be more important, is more difficult. There is need for a simple fast method of calculating the step transient response (preferably from the frequency response) for analytic purposes, and also for g... View full abstract»

    Transmission of color video presents a number of problems that were not encountered in monochrome transmission. The Bell System is attempting to improve transmission of chrominance information so that it is free of any phase and amplitude distortion, as well as reflections and external interfering energy.

  • Stable transistor oscillator

    Publication Year: 1955, Page(s):672 - 675

    Circuit arrangements are presented which considerably reduce the effect of changes in supply voltage and temperature on the frequency of a transistor oscillator. The oscillators described use n-p-n junction transistors and operate in the frequency range of 1 to 2 mc. In this range, a stability of 10 to 20 parts per million for 10-percent changes in supply voltage have been obtained compared with 2... View full abstract»

    Adjustable-speed drives of small and medium horsepower are divided into seven types and the general characteristics of each are described and compared with reference to their application in the paper industry. Mill experience suggests that the flexibility of the adjustable-voltage d-c drive and the simplicity of the wound-rotor drive are satisfactory for most drive applications. View full abstract»

    The different views of automation held by labor, industry, and the man in the street are discussed as well as how automation has developed logically in an evolutionary way. Automation is also shown to be necessary even to maintain the present rate of improvement in the standard of living and therefore an absolute necessity for continued American progress.

    The work which resulted in a proposed new system of nomenclature which may become the international standard within the next few years is outlined. It offers simplicity, ease of remembrance, the capability of expansion, and should prove useful to many other technical fields beside communication. View full abstract»

    Time-division multiplex systems once required either complex waveforms or multiple complex networks to overcome the master timing or synchronization problem. Now this newly designed quadriphase system, using a completely new approach to the problem, presents simplicity of design, operation, and maintenance, with similar reliability and excellent performance.
