    The proper selection and design of dielectric components for electronic applications must take into consideration the types of loading to be expected and the ambient temperature. It is suggested that 3-dimensional plots of the engineering properties vs. both time and temperature are necessary for best results. View full abstract»

    TO DETERMINE the success of a locomotive application, it is desirable to evaluate the effect on locomotive performance of both system and locomotive constants. In the process of designing an 11,000-volt 25-cycle rectifier locomotive, a generalized graphical method was developed for calculating speed-tractive effort curves, and evaluating relative importance of system and locomotive constants.

  • Power-class recloser for high-speed circuit clearing

    Publication Year: 1955, Page(s): 895
    Cited by:  Papers (2)

    CONDUCTOR BURNDOWN, one of the distribution engineer's major problems, focuses attention upon a need for higher speed interrupters. Automatic circuit reclosers with present “instantaneous” or “fast” time curves meet this need only partially because as much as 48 cycles is required to clear the circuit. A new design provides circuit clearing in one to three cycles, depen... View full abstract»

    Although the experiments reported here were conducted on relatively few specimens, the results are important. They definitely indicate that significant advances have been made in the maximum temperature of operation and in the forward-to-reverse resistance ratio of titanium dioxide rectifiers.

    THE NEED for wide-band impedance transforming devices for pulses of millimicrosecond duration has long been recognized. Because of the difficulty in constructing suitable lumped-parameter transformers the trend in recent years has been toward distributed systems, particularly of the tapered transmission-line variety.

    THIS study of the propagation mechanism of impulse creepage discharges over oil-immersed Kraft board was carried out using Leica and high-speed Boys cameras to record the progression of the discharges, as well as a special probe technique to measure the discharge potentials at various points along the channel. The electrode configuration used in these experiments consisted of a rod electrode on on... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (745 KB)

    The optimization of toroidal core shapes for use in self-saturating magnetic amplifiers requires a knowledge of the influence of id-od ratio on apparent core magnetic properties. A theoretical result was derived assuming a parallelogram-shaped basic hysteresis loop and an elaborate experiment was performed. The possibility of doubling the gain of a push-pull amplifier stage by changing the core he... View full abstract»

  • Transient response of sampled-data systems

    IT IS KNOWN that the z-transform method1−4 can be readily used for analysis and design of sampled-data systems. This method is essentially a Laplace transform technique in which the sampled output is related to the input by system functions in the form of z-transforms. These system functions can be generally regarded to consist of zeros and poles, in the form of rational polynomi... View full abstract»

    The engineer's role in maintaining the integrity and efficiency of the productive process may seem so obvious a goal as not to require special representation by any profession. At the same time the engineer must be aware of the hidden subtleties of his mission and of its relationship to that of other callings. View full abstract»
