    CERTAIN performance characteristics of magnetic recorders have decided effects on their design for various applications. There are four broad fields of application in which magnetic recorders are recognized: 1. Sound Recording, 2. Digital Data Recording, 3. Physical Analogue Data Recording, and 4. Video Recording.

    RESEARCH DEVOTED to developing rubber insulations resistant to micro-organisms has given two major results: 1. Compounds showing normal insulation resistance with no failures after 4 years in accelerated soil tests in which ordinary compounds fail in about 6 months; 2. Proof that the destructive organisms are fungi, and that these cause loss of insulation resistance and dielectric strength by grow... View full abstract»

  • Integrating instruments for quality control

    Publication Year: 1953, Page(s): 966
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (370 KB)

    IN QUALITY-CONTROL work, it is often necessary to determine the mean and the standard deviation of an important parameter, such as a dimension of the product. To accomplish this, a measurement system called an Evenness Integrator, Figure 1, has been developed for applications in which the material is tested while moving continuously. Since most of the necessary calculating functions are performed ... View full abstract»

    THE BASIC self-saturating, bridge-connected magnetic amplifier is shown in Figure 1. There the voltages appearing in series with the control windings are labelled as ec, the control voltage, and eb, the other possible sources of voltage within the control circuit. eb arises most commonly from two sources; first, from the changes of voltage drop across control circu...

  • Fault-resistance effect on ground fault current

    Publication Year: 1953, Page(s): 974
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (320 KB)

    GROUND FAULT currents may be reduced substantially when fault resistance is included in the fault circuit. The majority of faults that occur on a power system involve ground and occur between conductor and tower. When a fault occurs to a steel tower or grounded wood pole on a grounded system the footing resistance is included automatically in the fault circuit and the resulting ground current may ...

    The applications of voice-recording equipment discussed in some detail can be divided into four general groups: Announcements made directly to and providing a service to subscribers, such as weather forecasts and the time of day. Announcements to assist subscribers in connection with telephone service, that is, intercept announcements when an individual calls a vacant or disconnected terminal, or ... View full abstract»

  • Historical approach to speed and tie-line control

    THE PROBLEM of matching the generation to the load is basic with the electrical industry. Since the very earliest days of a-c systems, the maintenance of a frequency equal to the nominal figure at which the system operates has provided the simplest indication of this balance. Until the late 1920's very little consideration was given to anything more than approximate accuracy of frequency, with the... View full abstract»

    Several radio systems have been developed for locating a ship's position on the earth's surface and for tracking it. The measurement of phase, as is done in the Raydist systems, offers accuracies which exceed those of other methods. View full abstract»

    WHILE 2,6-di-tertiary-butyl-para-cresol (DBPC) has been established as a suitable oxidation inhibitor for transformer oil, its use in oil for reclosers has not been evaluated. A number of persons have raised the questions of the effect of DBPC on rate of settling, particle size, and quantity of carbon formed by an arc, and the effect of an arc on the inhibitor itself. In the present investigation,... View full abstract»

    Experimentation in an idealized soil showed a critical moisture content of approximately 4 percent by weight separated two distinctly different phenomena whereby heat is dissipated from buried heat sources. Above this moisture content relatively large quantities of heat per lineal foot are dissipated apparently by a circulation phenomenon. Below this content the soil rapidly dries out, materially ...
