Definitions

  • the beam itself will choose a path having' a slightly different radius so as to satisfy this requirement, and if the deviation is too large correct adjustment is ensured by varying the phase-shift angle of the positioning of the deection plates with respect to their junction points.
  • the direction points of the electrodes 22 may also be such that the beam will describe a smaller circle, in which case other electrodes S0 are provided at the inner side, which cause the beam to pass over the inner wall of the system 22.
  • the collecting electrodes are secondaryemission electrodes and at least at one of the collecting electrodes a further electrode is provided to which a suitable voltage is supplied for suppressing the secondary-emission of the associated collecting electrode.
  • a circuit-arrangement will be explained with reference to Figures 3, 5 and 6.
  • the circuit-arrangement shown in Figure 5 may, for instance, be used as a call-iinder in automatic telephony systems.
  • the beam steadily rotates over the electrodes until a subscriber takes the receiver from his apparatus and thus causes the voltage of an electrode 42 to drop so that the beam is immobilized in a denite position, That part of the beam passing between the electrodes 44 and 45 in Figure 6, may now be used as a telephony channel if this beam portion falls on a suitably positioned collecting electrode.
