Definitions

  • a controlling electrode is also constructed in the form of a frame, which preferably corresponds to the shape of the anode frame.
  • the frames may for instance be constituted by pieces of bent wire and, if desired, be strengthened against one another by insulating members in order to maintain a definite distance between them.
  • Figure 1 illustrates the arrangement of the electrodes according to the invention, in perspective view
  • Figure 2 shows a modification comprising a controlling electrode arranged between the cath- 'ode and the anode.
  • 1 is the anode, which is constituted by a simple frame of bent wire
  • 2 is the cathode consisting in a known manner of a plate the contour of which corresponds to the shape of the anode frame 1.
  • a controlling electrode 3 is arrangedbetween the anode 1 and the cathode 2, which controlling electrode is constructed in the form of a wire frame like the anode l.
  • anode and the controlling electrode may be made of a stamped sheet metal frame, of this casting, or the like.
  • a glow tube for the reception of pictures from a distance, for talking films and the like having a glow cathode in the form of a plate, and an 35 andde in the form of an open frame the bars thereof being all in a plane with the edges of the cathode plate.
