Definitions

  • This invention appertains to, in general, the multiplication of the frequency of alternating currents.
  • Figure 1 illustrates schematically an arrangement for moving an electron stream cyclically in a closed curve, the moving stream being utilized to shock excite, at a frequency higher than the cyclic movement of the stream, a tuned high frequency circuit, and
  • Figure 2 illustrates an arrangement similar to Figure 1 wherein the stream is moved linearly in a single plane.
  • a cathode 4 suitably energized by means of a transformer 6, although, if desired, cathode heating may be accomplished by direct current. Electrons emanating from cathode 4 are compressed or concentrated into a narrow stream by a negatively charged cylindrical screen or grid-like structure 8 through which they are attracted by the positive potential applied to a cylindrical anode l0 polarizedby a source of potential [2? Resistors l4, iii are placed in the anode and screen leads respectively to provide high impedances, for preventing short circuits,
  • the electron stream would be pulled through the anode It to the center point of annular insulator or element l8; but, by the action of deflector plates or electrodes, 22 and 24, 26, situated orthogonally about the stream, as shown, the stream is caused to rotate, in a manner more fully described hereinafter, so that itimpinges on insulator element I8 in a circular path indicated by dotted line 28.
  • element 18 Mounted on element 18 are a plurality of conducting members or targets 30 which, as shown, are alternately connected together and to conductors 32, 34' which in turn are connected to a balanced high frequency circuit 36 having movable U-shaped slides 38 therein for varying the tuning thereof.
  • tuned circuit 36 will be impulse-excited at a frequency equal to the frequency of rotation of the stream multiplied by a whole number, that is, the number of contacts on element Hi.
  • the tuning of circuit 36 should be adjusted to resonate at a frequency equal to half the number of contacts times the frequency of rotation of the electron stream.
  • Energy appearing in the tuned circuit '36 may be fed to a suitable transmission line 40 and radiated or transmitted over a suitable radiating antenna 42.

  • the lengths of the branch circuits 60, 62 and the positions of the feeders 64, 66, 68, are adjusted so that the required equal voltages are obtained between the plates 20, 22 and 21, 26; and so that no standing waves exist along the phasing line 55 and the line from the oscillator.
  • the electron stream will rotate about a circle or a closed curve whose radius is proportional to kE, with an angular velocity w.
  • Adjustment for the time of travel of electrons between the pairs of plates may be eliminated by arranging the electrodes 20, 22, and 24, 26, at the same point on the longitudinal axis of the stream in which case the time h becomes zero and 0 then becomes equal to If it is desired to multiply the frequency 11. times it is necessary to provide 2n contacts connected as shown to the balanced tuning system 36.
  • circuit 36 will be shock excited at the rate'of 2n alternate, positive and negative pulses per second, and, as it is tuned, the large voltages and currents peculiar to the resonant condition will be built up therein. If the contacts be only two in number the device will function as an amplifier, operating at the base frequency.
  • the electron stream be caused to pursue a circular path to accomplish frequency multiplication.
  • the path may be arranged in the form of an ellipse; and by proper arrangement of the phase and voltage differences between the two sets of control plates, a variety of other paths may be obtained.
  • the contacts, or targets should be located along the path so that the impulses occur at equal time intervals.
  • circuit 36 of Figure 2 will be shock excited at a frequency equal to the frequency of source 10 multiplied by a whole number, bearing a definite relation to the number of contacts, 18, used. If it is desired to multiply the frequency 11. times, it is necessary to provide (n+1) contacts, or targets.
  • the spacing of the contacts or conducting members should be so chosen that the stream during its motion will cause shock excitation at equal time intervals.
  • the spacing is given by the projection of the corresponding circular arrangement on a straight line.
  • the extent of the motion of the stream may be varied by suitably adjusting the amplitude of the exciting voltage.
