Definitions

  • the present invention has referenceto a so-called multi-vibrator circuit-arrangement.
  • such arrangement consists essentially of an even number of triodes mutually coupled in resistance amplifying circuits, the anode of the last triode being coupled retroactively to the grid of the first one.
  • Such system in its simplest arrangement (comprising but two triodes) is diagrammatically shown in Figure 1 of the accompanying drawing. Intense current impulses periodically occur in these systems, the frequency of said impulses being determined by the values of C and R.
  • triodes are replaced by tetrodes (doublegrid valves), between the two grids of which the periodically discharged condenser is interposed, one of said two grids being connected to the cathode across the leak resistance.
  • a multivibrator comprising a multi electrode space discharge device including two grids, a cathode, and a plate electrode. a condenser coupling the grids, a leak resist ance connecting one of said grids to the oathode, and the other grid being connected to the cathode through a source of high potential, and a connectionbetween the plate and said source of high potential.
  • a multivibrator comprising a tetrode having two grids, a cathode, and a plate electrode, a condenser coupling the grids, a leak resistance connecting one of said grids to the cathode, a source of high potential connected to the plate, and a resistance connect- .ing the other of said grids to the source of high potential.
  • a multivibrator comprising a tetrode having two grids, a cathode, and a plate electrode, a condenser coupling the grids, a leak resistance connecting the grid located adjacent to the plate, to the cathode, and a source of high otential connected to the other of, said gri s and the plate.
  • a multivibrator comprising a multielectrode space discharge device including two grids, a cathode, and a plate electrode, a condenser coupling the grids, a leak resistance connecting one of said grids to the cathode, and the other grid having a potential approaching that of the plate, and a source of potential connected to the plate.
