  • Steady-State and Transient Analysis of an Idealized Series-Connected Magnetic Amplifier

    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (1308 KB)  

    This paper presents a mathematical analysis of an idealized series-connected magnetic amplifier based on certain simplifying assumptions. The methods of nonlinear mechanics are used to obtain expressions for the input and output currents in the transient and steady state. Considerable attention is given to the problems of the existence and nature of time constants associated with the series-connected amplifier. View full abstract»

    This Bibliography lists all references on Magnetic Amplifier Devices and the Saturable Reactor Art known by or suggested to the author to mid-1951. It was prepared particularly as an aid to the accumulation of information on saturable reactors and saturable transformers as related to the magnetic amplifier art. Included are references on magnetic theory, measurements, core material characteristics, and rectifier characteristics pertinent to the development of magnetic amplifiers. Entries are arranged chronologically by year of publication, and alphabetically within each year by authors' names. Where there are two or more authors for an item, the item is listed only once, under the first authors' surname. If a book or article is written in a foreign language, the title has been translated into accepted English terminology and the language of the original has been noted in parenthesis following the English title. Following the title are given the usual bibliographic data on the author or authors, name of publication, date, and pages. View full abstract»

  • Predetermination of Control Characteristics of Half-Wave Self-Saturated Magnetic Amplifiers

    Publication Year: 1951 , Page(s): 2097 - 2103
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (2029 KB)  

    The control characteristic of a self-saturated magnetic amplifier is dependent upon the magnetic properties of the core material. A method is outlined for the experimental determination of the control magnetization curve, a plot of the locus of the minor dynamic hysteresis loops, which may be used with a firing angle analysis to predict the performance of simple magnetic amplifiers with high-control circuit impedance.

  • Progress in the Electric Power Industry

    Publication Year: 1951 , Page(s): 2059 - 2071
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (12242 KB)  

    The subject of this paper concerns the progress that has been made in the generation of electricity by steam and its distribution. It is significant that the two authors selected by your committee to discuss this subject are both power plant designers, and that their two working lifetimes cover the whole history of electric power generation since its beginning. That there has been progress in the electric power industry during this brief span of years is well illustrated by Figure 1, which shows that electrical residential rates on a national basis have a history of continuously lowering during the past 50 years while, at the same time, the cost index has been continuously rising. Where else than in the electric power industry can such a record of progress be shown? View full abstract»

  • Evaluation of Manual Methods of Resuscitation

    Publication Year: 1951 , Page(s): 2039 - 2041
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (649 KB)  

    A comparative evaluation of manual methods of resuscitation has been made possible by the development of a method for producing prolonged drug-induced apnea in normal human volunteers, using varying amounts of sodium pentothal and curare drugs. This renders the subject unconscious and unable to breathe, in which state he closely resembles the victim who requires artificial respiration. Tests on lung ventilation have revealed that all of the ``push-pull'' manual methods are two to three times as effective, as regards getting air in and out of the lungs, as the commonly used Schafer Method. Use of ``back-pressure'' instead of prone pressure almost doubles the ventilation with the Schafer Method. The Eve Rocking Method, a mechanical method, gives ventilatory volumes intermediary between the Schafer and the ``push-pull'' methods. The Pole-Top Method gives adequate ventilation and should be started immediately when a lineman requires artificial respiration. However, he should be lowered to the ground as soon as possible and one of the more efficient prone methods should be started. Tests on the circulatory effects of the methods have indicated that the Schafer Method was so inadequate that it had to be stopped in three out of nine cases because of the deteriorating condition of the subject. In each case one of the ``push-pull'' techniques was able to adequately sustain the subjects for full 15-minute test periods immediately before and after the Schafer test period which failed.

  • The Selection of Field Circuit Resistance for Synchronous Motors

    Publication Year: 1951 , Page(s): 2035 - 2038
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (819 KB)  

    The first three sections of this paper present a brief description of the methods presently employed by synchronous motor designers to control the starting performance and select the field discharge resistance. Subsequent sections propose a system whereby the designer or the user of a synchronous motor may change the starting performance through selection of the proper field circuit resistance.

  • A New 5,000-Volt Air-Break Contactor for Industrial Service

    Publication Year: 1951 , Page(s): 2030 - 2034
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (3370 KB)  

    This paper describes a line of air-break contactors made for controlling 100-horsepower to 3,000-horsepower motors on 2,400-, 4,160- and 4,800-volt systems. The design features compactness, accessibility, and long life. The arc-rupturing structure has a magnetic blowout and an arc chute which confines and interrupts the arc entirely within its boundaries for all currents which it is rated to interrupt.

  • The Closed Core Reactor

    Publication Year: 1951 , Page(s): 2026 - 2029
    Cited by:  Papers (2)
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (1645 KB)  

    This paper indicates the value of a closed iron core reactor as a source of fundamental reactive kilovolt-amperes. The saturation of the core provides a sharp transition point and a steep rise in reactive kilovolt-amperes when operating in the neighborhood of saturation. A practical method of analysis is outlined which permits the design of these reactors with engineering accuracy. Also included is expegimental data on a commercial reactor of this type.
