    The glaze storm which visited eastern New York State in December 1942 exceeded in area covered and weight of ice any previously recorded, according to the authors of this article, one of whom was active in the repair work throughout the storm and restoration period. The effect of the storm on electric-power systems in the area and the conclusions that can be drawn from it regarding heavy loading c... View full abstract»

  • Resonant electrical control systems

    Publication Year: 1943, Page(s):436 - 439
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (3842 KB)

    The electrical phase shift between the current and the applied voltage in a series-resonant circuit as the resonant-circuit tuning is varied is used as the basis of operation for resonant electrical control systems. The author discusses application of such systems to aircraft and industrial problems, and to single and multiphase radio control. View full abstract»

  • Refresher for dielectric calculations

    Publication Year: 1943, Page(s):445 - 448
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (930 KB)

    In making dielectric calculations, it is important to be able to correlate the fundamental characteristics of the dielectric material with measured quantities such as current, loss, power factor, and capacitance. In this article the author has attempted to co-ordinate in a simple manner all the relations necessary to dielectric computation. View full abstract»

    The present war emergency requires that the maximum use be made of existing equipment and systems and that a minimum of critical material be used for new equipment. This publication, as well as other guides and reports in this series, has been prepared for the information of users during the war emergency. Upon termination of the war emergency, they will be reconsidered by the Standards committee ... View full abstract»

  • Design relationships for D-C generators for use in aircraft

    Publication Year: 1943, Page(s):613 - 615
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (4647 KB)

    The paper sets forth the different operating conditions met with in aircraft generators as compared with standard types of industrial generators. It discusses certain features inherent in applications to aircraft, such as reliability and light weight. Certain requirements in both electrical and mechanical design are imposed by the fact that a plane is flying through varying altitudes resulting in ... View full abstract»

  • Frequency modulation for power-line carrier current

    Publication Year: 1943, Page(s):616 - 619

    FREQUENCY modulation is known to most people today as a system of broadcasting that is remarkably free from the effects of interference and is capable of providing high fidelity reception. These advantages have been realized largely by employing frequencies of 40 megacycles and higher which are well above the present broadcast band. A great amount of effort has been devoted to this field, and ther... View full abstract»

  • The calculation of unbalanced magnetic pull in synchronous and induction motors

    Publication Year: 1943, Page(s):620 - 623
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1250 KB)

    Unbalanced magnetic pull may be defined as the net sideways force between the stator and rotor of an electric machine resulting from a difference in the air-gap flux densities on opposite sides of the machine. This difference in flux density is, in general, caused by a difference in the air gaps on the two sides. View full abstract»

  • Characteristics and applications of selenium-rectifier cells

    Publication Year: 1943, Page(s):624 - 629
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (4746 KB)

    The rectification properties of selenium cells were first discovered in the year 1883. C. T. Fritts described them in the American Journal of Science.11,12 However, they were never used to any extent, except possibly as photocells. After the introduction of the copper-oxide rectifier, research activities were stimulated, and selenium cells were again rediscovered. The first commercial c... View full abstract»

  • A new high-interrupting-capacity fuse for voltages through 138 kv

    Publication Year: 1943, Page(s):630 - 634
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (20568 KB)

    The reliable performance of high-interrupting-capacity fuses in the intermediate voltage field has led to an increased interest in the application of such fuses for the higher voltages. Unfortunately, a fuse for the higher voltages cannot be made by simply enlarging or lenghthening the lower-voltage devices. To interrupt the higher currents in a reasonable structure, arc lengths must be kept short... View full abstract»

  • Subcenter switching systems for teleprinter tie lines

    Publication Year: 1943, Page(s):635 - 641
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (13834 KB)

    One of the means used by the telegraph companies for improving the speed of their service is the provision of printing telegraph circuits between their central offices and the offices of many users of the telegraph. In the beginning, circuits of that type were restricted to patrons whose volume of telegraph business and proximity to a central office justified the expense involved in their installa...

    Airplane circuit breakers are recognized as important units in the electrical systems of military aircraft. The design of such circuit breakers can be combined with switching and contactor functions. This makes possible the use of well-developed switch and contactor structures. The design of such circuit breakers must provide for operation under the very exacting requirements of military aircraft ... View full abstract»

    The war, with its attendant shortage of critical materials, has led to a considerable increase in the number of tapped lines. This paper deals with the method of protecting circuits of this kind under the three headings: 1. Pilot-wire protection, a-c and d-c schemes. 2. Carrier-current protection. 3. Other protective schemes. Directional overcurrent or network. Distance type. Three-terminal lines ... View full abstract»
