    Now, as never before, the opportunity for professional success awaits every engineer who has the imagination and initiative to take advantage of it. In today's complex industrial society there is a dual demand for his talents, either as a creative, individual engineer, or as a manager of engineering work and the business enterprise as a whole.

  • Impact of the atomic energy program on the electrical industry

    Publication Year: 1954, Page(s):592 - 596
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (880 KB)

    Starting with a power requirement of 225 megawatts at Oak Ridge during the war, the Atomic Energy Commission's demands on the suppliers of power will be approximately 6,500 megawatts. How the problems raised by these unprecedented demands are being solved is a tribute to American engineering talents. View full abstract»

    Alessandro Volta, a physicist whose experiments in contact-electricity led to the discovery of the voltaic cell and provided a practical source of continuous electric current, was responsible for the forward move that brought electricity from a plaything of the curious to a most important tool in the hands of mankind.

  • Fundamentals of flashing of diesel-electric motors and generators

    Publication Year: 1954, Page(s):603 - 608
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (986 KB)

    Flashing is one of the important considerations in the manufacture and operation of electric equipment for diesel-electric locomotives. Its importance has increased because of the large number of high-speed and high-powered road locomotives which have been put in service during the past few years. Minimization of these effects can be had by a better understanding of the basic causes of flashing. View full abstract»

  • Application of shunt capacitors to network systems

    Publication Year: 1954, Page(s):609 - 613
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (887 KB)

    A low power factor has been caused in many systems during the summer months which is becoming an increasing problem in voltage regulation of distribution systems and networks. The installation of capacitors on the low-voltage side of networks is one way to increase materially the available capacity of network transformers. This and other applications are discussed together with a description of ne... View full abstract»

  • A new 115-kv stored-energy-type capacitor switch

    Publication Year: 1954, Page(s): 614
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (208 KB)

    SHUNT CAPACITORS for supplying leading reactive kilovars for power-factor correction have been used on power systems for a great many years, but it is only recently that large shunt capacitor banks have been applied extensively to power systems at primary transmission voltages. Such applications have given rise to a requirement for satisfactory high-voltage switching equipment at minimum cost. Up ... View full abstract»

    This scanner overcomes the chief limitations of the lathe-type scanner. It is small, light, and flexible as to its optical system. A moving frame mount can be substituted for the typewriter-style roller when inflexible or bound copy is to be scanned. View full abstract»

  • Transient performance of servomechanisms

    Publication Year: 1954, Page(s): 620
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (196 KB)

    THE UTILITY of servomechanisms depends upon the speed, stability, and accuracy of their responses. In order to achieve the best performance, it is often expedient to employ, as a correction signal in addition to the error, either the derivative or the time integral of the error, or both. The servomechanism then is said to have derivative or integral control. View full abstract»

  • Applying short-time memory units to compensators

    Publication Year: 1954, Page(s): 621
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (208 KB)

    A COMPENSATOR is a device cascaded with a control system so that the resultant output, or controlled variable, q(t) is some function of the input, or command signal v(t) (see Fig. 1). This article suggests methods for the design of several different compensators each of which contains a short-time memory unit as an integral part of its structure. The analysis is limited to the design of linear fol... View full abstract»

  • Eddy-current phenomena in ferromagnetic materials

    Publication Year: 1954, Page(s): 624
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (185 KB)

    THIS ARTICLE presents a new treatment of eddy-current phenomena in solid iron and other ferromagnetic alloys based upon a suggestion by A. G. Ganz.1 The new treatment is developed logically, beginning with the familiar problem of eddy currents in an infinite region of constant permeability, bounded by a plane surface where excitation is applied. The concepts of phase shift and damping a... View full abstract»

    The voltages required for perception with good contacts are low in comparison to the 120-volt house circuits and it is essential that reasonable measures be taken to control leakage currents in household appliances and electrically operated hand tools and thus prevent adverse public reaction to the increasing use of electricity in the home and in industry.

  • Co-ordination of fuel cost and transmission loss

    Publication Year: 1954, Page(s): 631
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (175 KB)

    A NUMBER OF METHODS have been described for developing a set of loss constants for a power system network with which the total or incremental losses can be calculated by matrix multiplications. These values then may be applied to the dispatching of power systems through comparisons of incremental fuel costs and incremental transmission losses. A new approach determines the per unit incremental los... View full abstract»

    OIL IS USED widely in electric apparatus as an insulating medium. Past investigations on the breakdown mechanisms of oil insulation generally were restricted to uniform field conditions and slow varying voltages. However, electric apparatus frequently contain some nonuniform fields and often have to pass impulse acceptance tests. View full abstract»
