  • A new high-current switch for electrolytic and electrothermal applications

    Publication Year: 1954, Page(s):1 - 6

    THE marked increase in electrolytic cell-operating currents in the past decade has emphasized the need for a simple, dependable, and inexpensive high-current switch for use as a cell short-circuiting switch. In the electrothermal field, the magnitude of furnace currents has also been increasing as it has become evident that higher furnace currents lead to better operating economies. Earlier types ...

  • Linear compensation of saturating servomechanisms

    OPTIMUM switching of second-order contactor servomechanisms has been treated in the literature. A method of approximating this performance without the use of relays or computers consists of substituting a particular type of network and a limiter for the computer and relays. A procedure is given for obtaining the characteristics of this network. It is illustrated by examples and experimental result... View full abstract»

  • The transient performance of servomechanisms with derivative and integral control

    THE utility of servomechanisms in their many applications depends on the speed, stability, and accuracy of their responses. These three characteristics, or the lack of them, may be observed in the responses of a servomechanism to test inputs. The error, which is the difference between the input and the output of the device, is used to actuate the control in a direction which tends to remove the er... View full abstract»

    This paper discusses the fundamental processes involved in the production of current in a lead acid cell, particularly as they are related to the peformance of the cell when furnishing variable or intermittent loads or a combination of both. A method of determining the size of cell required for various duty cycles is described and a general equation is derived, which, with certain restrictions, wi... View full abstract»

  • Some aspects of the charge and discharge processes in lead-acid storage batteries

    Publication Year: 1954, Page(s):22 - 34
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (993 KB)

    THE equilibrium relations of lead-acid storage batteries have been extensively studied. The double-sulfate theory proposed by Gladstone and Tribe1 has been substantiated by analytical methods,2 thermodynamic studies,3 and electromotive force measurements of galvanic cells simulating the charged state of the electrochemical system.4 It is well recognized that on discharge one equivalent each of lea...

  • A reappraisal of the economics of railway electrification: How, when, and where can it compete with the diesel-electric locomotive?

    Publication Year: 1954, Page(s):35 - 51

    The diesel-electric locomotive has been universally substituted for the steam locomotive on most of the railroads in this country. Railway electrification has not had further application during this period. Many believe this to be an indication that the economies of the diesel over the steam locomotive apply equally to electric operation as well. This opinion is debated. Power costs, investment co...

  • Contactor servomechanisms employing sampled data

    Publication Year: 1954, Page(s):51 - 64
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1042 KB)

    This paper introduces a sinusoidal response method of analysis and synthesis of a contactor servomechanism employing sampled data. Because of the presence of sampler, clamper, and contactor, the system is discontinuous in time as well as being nonlinear. The sinusoidal method provides a useful guide in analysis and synthesis. It enables one to determine the conditions of occurrence of self-sustain... View full abstract»
