    The united States Government exhibit for the 1958 Geneva Conference included a simulation of the main portion of the entire Experimental Boiling Water Reactor (EBWR) plant. The total simulation consisted of two operating panels similar to the EBWR control panels and an animated model of the plant. This discussion is limited to the computer technique utilized to accomplish a linear simulation of th... View full abstract»

  • Transients in logarithmic count-rate and period meters

    Publication Year: 1960, Page(s):362 - 369

    It has been found desirable and practical, in designing automatic control devices for starting nuclear reactors, to measure flux transients at extremely low flux levels, using the output from neutron-counting circuits. In general, a logarithmic count-rate circuit is used, and the logarithmic indication of flux thus obtained is differentiated electrically to yield an indication of the period of the...

  • A digital start-up control for air-cooled nuclear reactors

    Publication Year: 1960, Page(s):369 - 375
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1236 KB)

    In bringing a nuclear reactor up to power, the flux level goes through as many as 8 to 10 decades from the off position through full power. Somewhere within this range of power the reactor goes critical (effective multiplication factor equals one). This point where criticality is reached may be 7 decades below the full power point. In most stationary water-cooled reactors, this total spread is div... View full abstract»

    By the use of feedback amplifier techniques considerable improvement has been made in the speed and/or stability of the familiar electrometer tube micromicroammeter. Simplicity and compactness have been retained. With 100 feet of input cable, the amplifier has a 150-millisecond time constant at 10¿11 amperes full scale with 0.05% per day stability.

  • Instrumentation for experimental reactor kinetic studies

    Publication Year: 1960, Page(s):384 - 388
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (941 KB)

    Reactor power excursions involving stable periods ranging from a few seconds to 2 ms (milliseconds) have been experimentally investigated in the course of the Kinetic Experiments on Water Boilers (KEWB) program conducted by Atomics International for the U.S. Atomic Energy Commission. Reactivity introduction, power and temperature measurement, and data analysis have imposed some unique requirements... View full abstract»

  • Portable dynamic electronic speed-torque indicator

    Publication Year: 1960, Page(s):388 - 392
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1007 KB)

    The concept of instantaneous observation of the complete speed-torque characteristic of a motor while it accelerates from standstill to full speed is based on the assumption that a large percentage of the torque is utilized in acceleration of the inertia if the motor is otherwise unloaded. The basic instrument needed is an accelerometer with dynamic response capable of indicating the true starting... View full abstract»

  • The relative merits of incremental and conventional digital computers in air-borne real-time control

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1505 KB)

    In the conventional or general-purpose digital computer, operands are transferred in their entirety from one functional block to another. The inputs and outputs of such a block are simply the values of the constants and variables concerned. In the incremental computer, however, only portions of the operands are transferred. The inputs and outputs of a functional block are increments of the quantit... View full abstract»

    Equivalent circuits have been established by Kron and others who used finite-difference and integral forms of Maxwell's equations and equations of mathematical physics in general, and in many cases applied them to actual problems in obtaining solutions. Examples of application are to problems of compressible and incompressible fluid, electromagnetic fields, elastic fields, and heat flow. See refer... View full abstract»

    For some time, the need has been apparent for a high-performance receiving tube to operate in the very-high-frequency (vhf) region up to 450 mc (megacycles per second) and to bridge the gap between available receiving tubes and high-performance transmitting tubes. This tube should be capable of operating as an oscillator, amplifier, or frequency multiplier. Desirable features of such a tube are th... View full abstract»

    The designer of a computer control system for continuous operation in an industrial process must assume two roles. One role is that of the computer expert responsible for assuring that the best computer techniques are used. The other role is that of the process application expert responsible for assuring that the system conforms to the best in process design practices. View full abstract»

    This paper examines the operation of a magnetic servoamplifier in which the load circuit includes the resistance and inductance of a servomotor control winding shunted by a tuning capacitor. Amplifier parameters (tuning capacitor C, limiting resistor Rs, and quiescent firing angle ¿) are being optimized for best linearity and maximum motor torque. Amplifier motor transfer characteristics are esta... View full abstract»

  • The properties of pole and zero locations for nondecreasing step responses

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1064 KB)

    A form of response to a step input in a physical system is the nondecreasing type, which is of interest to the circuit designer, especially when an overshoot in the step response is objectionable. The purpose of this paper is to discuss the properties of the pole and zero locations of rational system functions whose step responses are of this form. The few known properties of this nature are scatt... View full abstract»

    A new approach to automatic voltage control of a regulating transformer was sought in conjunction with a rectifier transformer and semiconductor rectifying elements connected in a 6-phase double-way circuit. Conventional control for a load tap changer is not designed to detect and correct for fluctuations directly in a d-c line, yet close control of the voltage across the 40-kv rectifier output wa...

    Automatic data processing is a tool for transforming, processing, and calculating information. If one accepts this fact, one should be prepared to describe the fundamental capabilities of automatic data processing. Since communications is itself a tool, it is instructive to attempt to describe its fundamental nature in a similar frame of reference and compare the two. The results of such a simple ...

    Measurements have been made of moon-reflected radar signals transmitted by the Royal Radar Establishment from Malvern, England, and received by the Electrical Engineering Research Laboratory of The University of Texas at Austin, Texas. These supplement monostatic radar measurements made by a number of organizations and a few bistatic measurements which have been noted in news articles and mentione... View full abstract»

    The R1 transposition system (sometimes coded R1¿5) has been employed in many cases for transposing rural open-wire telephone lines. These have been both subscriber lines and trunk lines, voice and carrier. The R1 system has the attractiveness of: 1. Patterns lending themselves to simplicity in engineering and construction. 2. No transposition ¿sections¿ or ¿S¿ poles. 3. No quantitative limits... View full abstract»
