    IN his article in the January issue of Electrical Engineering, C. S. Purnell, Chairman of the Finance Committee, pointed out that the budget for the year beginning October 1, 1954, anticipates a deficit of about $106,000. In the calendar of the Institute, a budget year overlaps portions of two fiscal years. It has been done that way in an attempt to make the budget year coincide approximately with...

    Among engineers, their professional status is one of today's live questions. That question is frequently dismissed with a statement that each engineer must improve his individual status by acting and living in a professional manner—that only thus will the status of the profession as a whole be improved. Some observations of Dean Freund, presented in this brief and thought-provoking article,... View full abstract»

    PREVENTING the formation of ice on outside surfaces of aircraft windshields is a serious problem to the designers of all-weather aircraft. The development of a transparent conductive film which can be applied to a glass surface promises to offer an ultimate solution to this problem. By means of the transparent conductive film, electric energy can be dissipated near the windshiel... View full abstract»

  • Implementation of a research program for the electrical utility industry

    Publication Year: 1955, Page(s):104 - 109
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (845 KB)

    The electrical utility industry has a need for more extensive research activities to investigate basic problems and to provide for its long-range needs. Such a program should attract the interest of engineering students, who oftentimes believe that the power industry offers little opportunity for creativeness. View full abstract»

    Are the future electrical engineers being trained broadly enough in the sciences? This question has been given serious study at the Massachusetts Institute of Technology, with the result that major changes have been made in the undergraduate electrical curriculum, so as to better equip the students with technical substance and professional vision.

  • Nuclear power plants for ship-propulsion Application

    Publication Year: 1955, Page(s):116 - 121
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (944 KB)

    The application of atomic power to the C-4 Mariner-Class cargo vessel is analyzed in some detail. It shows that at present nuclear power cannot compete on a strictly economic basis with conventional power plants. However, other factors such as weight, space, speed, and range considerations would also enter into any complete evaluation of the application of atomic power for marine purposes.

  • Field tests on a 100-megawatt rectifier installation

    Publication Year: 1955, Page(s): 122
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (199 KB)

    THE 100-megawatt rectifier station at the Robert P. Patterson Plant of the Reynolds Metals Company is the largest concentration of d-c power on a single bus in this country. Power for the plant is obtained from 24 double-Y ignitron rectifier assemblies, each rated at 5,208 amperes and 800 volts. In March 1954, an extensive field-test program, involving both load switching and arc backs, was conduc... View full abstract»

  • Effect of synchronous-machine transient rotor saliency

    Publication Year: 1955, Page(s): 123
    Cited by:  Papers (1)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (194 KB)

    IN most studies of power system disturbances made on the a-c network analyzer, the transient rotor saliency of the synchronous machines is neglected. The validity of this assumption is well established. However, in some cases it has been desirable to measure the variations in several of the bus voltages during the disturbance. When the bus is electrically near to a synchronous machine (in the limi... View full abstract»

  • Lighting a modern refinery process unit

    Within the past few years more attention has been paid to increasing and bettering illumination in work areas. While progress has been made in outdoor lighting, there is room for improvement in those exteriors where 24-hour operations need adequate lights. Although this article applies to a refinery, there are ideas applicable to many industries. View full abstract»

    UNDER certain conditions, the heart may lose its rhythmic pumping action and cease the circulation of blood. This situation is known as ventricular fibrillation and may occur during surgical procedures or as a consequence of electric shock. Normal heart action may be restored by passing an electric current of suitable characteristics through the heart. In the operating room, defibrillation is acco... View full abstract»

    THE analysis of magnetic amplifiers through the use of difference equations will result in a different view of the mechanics of operation of the magnetic amplifier. It shows that all magnetic amplifiers operate upon the same basic principles, and that these basic principles are demonstrated by the operation of the basic half-cycle response magnetic amplifier shown in Fig. 1. The purpose of the ana... View full abstract»

    ONE of the most powerful mathematical methods for analysis of sampled-data systems is known as the z-transformation method. The z-transform is obtained by substituting z for est in the Laplace transform of the sequence of samples. C(z) is obtained in closed form with the aid of Table I. View full abstract»

  • Evaluating the effect of nonlinearity in a 2-phase motor

    Publication Year: 1955, Page(s): 142
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (168 KB)

    A 2-PHASE induction motor is inherently a nonlinear device, but normal practice in the design of servomechanisms has been to represent it with a linear transfer function. This is obtained by assuming that the speed versus torque curves of the motor, for fixed reference field voltage and various values of control field voltage, are parallel straight lines.

  • Permanent magnet excited synchronous motors

    FRACTIONAL-HORSEPOWER synchronous motors are generally available for quantity production in only the reluctance or hysteresis types. The reasons for this are: the simplicity of their rotor constructions, because of the omission of d-c excitation; and the possibility of assembling the rotors of either type in standard induction motor frames. Unfortunately, these advantages are offset by inferior pe... View full abstract»
