    From the first neon discharge tubes of 1910, a range of devices has evolved covering a remarkable diversity of applications. Voltage regulators and reference tubes are available for voltages from 55 V-27 kV and currents from 1 ¿A-100 mA. Relay tubes offer current gains between 106 and 1012 and provide continuous control of loads of up to 2 kW or switch peak loads of 10 MW. The stepping tube has b... View full abstract»

  • The design of second-harmonic detector heads and their application to the reading of digital information and the measurement of low speeds of rotation

    Publication Year: 1964
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (2286 KB)

    Two applications of the second harmonic principle are outlined and the design of suitable detector heads is detailed. The first application relates to the detection of binary recorded information on magnetic tape. The detector head described provides an output signal which is a direct measure of the flux Unking the head at any instant and does not depend for its output signal on relative motion be...

  • An equalizer for an electro-magnetic vibrator system employing analogue computing techniques

    Publication Year: 1964, Page(s):125 - 132
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1048 KB)

    The response characteristics of a typical vibration system are considered and the transfer functions of the various resonances are given. It is shown that by employing analogue computing techniques it is possible to construct an equalizer for the system by simulating the reciprocal of its characteristic. The design for such an equalizer is described and details are given of equipment, which enable... View full abstract»

  • Sensitivity of an oscillator to periodic conductance changes

    Publication Year: 1964, Page(s):133 - 148
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1423 KB)

    The oscillator is considered as a means whereby changes in the conductance of its grid tuned circuit may be detected. A brief treatment of variable circuits is given, together with a physical interpretation of the results. Expressions are derived for the output voltage obtained from the oscillator when its grid tuned circuit conductance is varied in a periodic manner, and the results of experiment...

  • The prediction of the optimum noise performance of a reflection cavity maser

    Publication Year: 1964, Page(s):149 - 152
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (432 KB)

    Maser performance depends on the microwave circuit, on the total concentration of paramagnetic centres in the energy states used in the crystal and on the degree of inversion of population differences which can be obtained by pumping. At any temperature there will be an optimum concentration for maximum performance and to determine this optimum a knowledge is needed of certain parameters. Although... View full abstract»

  • The performance and the flux patterns of a special shape multi-aperture device

    Publication Year: 1964, Page(s):153 - 163
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1400 KB)

    This paper describes a special-shaped multi-aperture device which can perform the operation of a circuit element equivalent to a two-input AND gate. One interesting feature of this device is that it may be interrogated non-destructively. Although this shape basically performs the AND function, it is possible for it to perform a wider range of logical operations, such as OR-AND, negation, exclusive... View full abstract»
