  • Arcing time of high-voltage air-break contactors at low currents

    Publication Year: 1953, Page(s):145 - 150

    A high-voltage air-break contactor must be able to interrupt the circuit to motor loads or static loads covering a wide current range. Considerable attention has been given to the ability of contactors to interrupt fault currents, but little has been published on the problem of obtaining satisfactory performance at low currents. The difficulty at low currents is one of getting acceptably short arc... View full abstract»

  • Drag-Cup A-C tachometer with constant-current excitation

    Publication Year: 1953, Page(s):150 - 152

    AS A consequence of recent publication of a general analysis of the drag-cup a-c tachometer,1 numerous inquiries have been received relative to the desirability of operating such a device from a current source. Hence, a brief examination of the possibilities of such operation seems worth while. In these communications the ideas expressed about constant-current operation have been to the effect tha...

    This paper explains briefly the progress of dieselization on the two major railways in Canada. It outlines specific electrical problems encountered and suggests the developments desired to meet their particular type of operation. Information given is in terms of technical reciprocity with the numerous railways in the United States. View full abstract»

  • Design factors favoring diesel-locomotive electrical maintenance

    Publication Year: 1953, Page(s):155 - 157
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (260 KB)

    Many details of design of electric apparatus and its installation in the locomotive have a profound effect on the amount and quality of maintenance attention it requires and receives in service. Simplicity and ruggedness are basic. The influence of design upon diesel-locomotive electrical maintenance cannot be overemphasized. This applies not only to the design of the electrical apparatus but also... View full abstract»

  • An analytical solution of heat flow versus wire temperature for electric cables buried in plaster

    Publication Year: 1953, Page(s):160 - 165

    Complete electric heating installations are becoming quite general throughout certain areas. A popular type is the resistance cable embedded in plaster to form a radiant panel heater. For long cable life and maximum safety, the cable temperature must not exceed a definite limit. Various investigators have derived equations describing the temperature throughout the panel. However such equations do ... View full abstract»

  • A differential-analyzer study of certain nonlinearly damped servomechanisms

    Publication Year: 1953, Page(s):165 - 170
    Cited by:  Papers (2)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (702 KB)

    A servomechanism must hold its error or the difference between input and output, to as small a value as possible. If a large error appears as a result of a rapid change in the value of an input position signal, then high acceleration and high output speed are desirable, and these in turn are favored by a low damping ratio. When the error is near zero, the speed should be reduced rapidly so that ov... View full abstract»

  • Hydraulic servos incorporating a high-speed hydraulic-amplifier actuated valve

    Publication Year: 1953, Page(s):175 - 180

    Electrohydraulic systems have certain advantages over pure electromechanical systems, which make them particularly suitable as an adjunct to electronic control for high-power level actuation. The main factor which has limited the application of hydraulic actuators until recently has been the awkardness of the control systems required. However, developments in the technique of controlling hydraulic... View full abstract»

  • Limiting in feedback control systems

    Limiting effects exist in feedback control systems because of the restricted range of operation of components or because of purposeful limiting introduced for the protection of equipment. Such limiting effects increase the difficulties associated with the analysis and synthesis of systems because of the nonlinear mathematical relations which result. As such effects can markedly modify system perfo... View full abstract»

  • Application and operation of D-C drives on rubber calenders

    Publication Year: 1953, Page(s):194 - 201
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (692 KB)

    D-C motors are used almost universally on rubber calenders to obtain a wide speed range, good speed regulation, maximum braking under emergency conditions, suitable matching of speeds of the auxiliaries with the calender, and on the modern drives, electrical tension regulation of the fabric. The majority of the calenders in operation are driven by adjustable speed d-c motors with conventional arma... View full abstract»

    Users OF resistance welding equipment are finding ¿presswelding¿ to be ideally suited to many of their high-production applications. In its general concept, presswelding may be likened to present-day stamping-press practice; however, instead of forming or trimming, the weld press produces from 16 to 160 spot welds practically simultaneously on a given assembly. The welding press also differs fro... View full abstract»
