    FREQUENCY-RESPONSE techniques are among the most powerful tools in the hands of the feedback control systems engineer. Perhaps of greatest use today are the attenuation and phase-angle plot techniques developed by Bode. These techniques are particularly effective in analysis and synthesis of stable systems in establishing the relative stability of a system.1 Although it is possible to estimate the...

  • Improved D-C high-potential testing of insulation systems in low- and medium-voltage D-C equipment

    Publication Year: 1959, Page(s):186 - 199
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (6889 KB)

    Elimination of unexpected breakdowns in d-c high-potential testing is made possible by observing the electrical noise caused by ionization. (The terms ionization and ionization discharges are used as common terminology to refer to charge redistributions as a result of gaseous breakdowns in the insulation systems; see Appendix I. However, it will be more appropriate for the purposes of this paper t... View full abstract»

    THE PROBLEM of developing a practical method of instrumentation for production use at the Westinghouse Electric Corporation has been advanced by the combined interest and efforts of research, development, and manufacturing people within the company. The use of instrumentation for resistance welding involves wide economic considerations in product quality and production costs and has thereby greatl... View full abstract»

  • The life expectancy of class a random-wound motor insulation as determined by AIEE standard no. 510 test procedure

    Publication Year: 1959, Page(s):224 - 228
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1835 KB)

    TEST PROCEDURES for determining the relative life expectancies of different insulation systems for random-wound machines, using either complete motors or models, called motorettes, are provided for by AIEE no. 510.1 The procedure calls for subjecting the motorettes to successive periods of high temperature in ovens, followed by vibration and exposure to moisture, and an overvoltage check. The cycl... View full abstract»

  • A relay-type feedback control system design for random inputs

    Publication Year: 1959, Page(s):228 - 233
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1917 KB)

    EARLIER literature has suggested the design of the so-called optimum relay control system, where the term ¿optimum¿ is based on the system having the fastest possible response in terms of reducing the error to minimum following a step or ramp input.1¿4 It has been pointed out that these systems are optimum only in this special sense, and that their response to other types of input may be undesi...

  • Detector car history and new developments

    THE rail detector car is an assemblage of specialized test equipment mounted on self-propelled railroad cars and is used for the detection of all types of defects that develop in railroad rails. The story of detector cars should start a few years before there were any such cars. Before 1926, the railroads were faced with a serious and fast-growing menace to their very life: the breaking of rails. ... View full abstract»

  • Aluminum bus for shipboard application

    Publication Year: 1959, Page(s):239 - 247
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (7075 KB)

    THERE is special interest in aluminum for shipboard use because of the savings realized in weight and because of shortages in copper that occur especially in times of national emergency when shipbuilding is at its peak. Although aluminum has been considered for cable conductors for shipboard use it is generally without over-all advantage because the larger conductor size results in a greater volum...

    THE USE of an analog computer, particularly one of the electronic differential analyzer type, in the analysis and design of feedback control systems has been well established in the past few years. Quite often, however, a detailed computer investigation of a control system is not necessary. For example, in some instances the control system may contain only a few components which can be represented... View full abstract»

  • A new chart relating open-loop and closed-loop frequency responses of linear control systems

    Publication Year: 1959, Page(s):252 - 255

    CONTROL ENGINEERS generally adhere to the use of frequency response as the fundamental tool for feedback control systems. Through the use of the Nichols chart,1 the open-loop characteristics can be quickly converted to the closed-loop characteristics. The performance of control systems can be estimated according to the gain and phase margins and the magnitude of peak M. Although actual performance... View full abstract»

    PRESENT and future aircraft requirements for electric power are constantly increasing, with operational requirements of speed, altitude, and equipment imposing greater loads on the electric generating systems. The need therefore exists for generators capable of operating at higher temperatures than those presently available. View full abstract»

    THE ELECTRICAL RESISTANCE of storage batteries is important to two groups of people. Designers of telephone equipment need to know the resistance to alternating current in order to evaluate the cross talk between simultaneous telephone conversations which must pass through the central station battery. They must also be able to evaluate the amount of filtering required to remove hum, noise, and swi... View full abstract»

  • The effect of variable high-altitude humidity on the wear of nondusting brushes

    Publication Year: 1959, Page(s):263 - 267

    THE important effect which water vapor has on the performance of carbon brushes has been recognized for many years. Prior to 1935,1 cases of excessively short brush life were found to be due to the low humidity of the cold air of midwestern United States winters. Early in World War II, when bombers began flying at altitudes above 20,000 feet, this low-humidity problem was more spectacularly demons... View full abstract»

  • Development of fuses and terminals for high-temperature applications

    COMPONENTS TO BE developed under the Hotelec program include fuses, terminals, and splices. The most significant new requirement of this program as it affects these components is the extension of the temperature level to 850 F (degrees Fahrenheit) for terminals and splices, and to 600 F for fuses; these are ambient temperatures with conductor temperatures reaching 1,000 F. Other significant requir... View full abstract»
