Definitions

  • a number of supporting rods 2 are xed in a to provide the body I8 with a projecting collarv ring l which is clamped around the stem A of as a seat for the cathode so as to compulsorily the tube.
  • These supporting rods carry an annusecure the correct interspace between the face of,
  • the lead-in conductors to the individual electrodes are carried through slots in the insulating rings as far as these cannot be applied from the outer side of the structure.
