Definitions

  • Neut 'alized tube transmitting apparatus often olfer difficulties in that the neutralizing condensers fail in the requisite constancy of the capacity.
  • the dielectric 0111 the anode volt-a e of continuous current but also the alternating current voltage is in eixstence.
  • the magnitude of the capacity will be reduced, it is necessary for the sake of compensation to increase the superficial area of the plates.
  • the capacity of space that is the capacity between the plates and the remaining structure of the transmitting apparatus and earth respectively, will become very great at the same time.
  • a resistance VV or VV respectively one end of which leads to the point 3.
  • the latter is in connection with the positive pole of the source An for the anode current.
  • the point 3 shows the same potential of continuous current as the plates of the variable neutralizing condensers N and N at the side of the anode.
  • the resistances IV, and Wlll flow no contmuous current and in consequence no drop of voltage can be caused, the same continuous current volt- ,7
  • the arrangement according tothe invention ensures, that the same continuous current volt age is present on both sides of the variable neutralizing condensers, in other words that these condensers are bridged for the continuous current voltage.
  • the alternating currentvoltage present at such a condenser is at the same time reduced through the condenser F, or F respectively likewise connected.
  • variable condenser may be of small dimensions and the capacity of space can be rendered slight.
  • the stationary condensers proper possess already a small capacity of space, since mica may be selected for these, which material possesses a higher dielectric constant and resistance power against puncturing than air.
  • Neutralized tube transmitting apparatus of the character described comprising in combination a variable neutralizing c'ondenser and means for bridging the latter'in respect of continuous current voltage.
  • Neutralized tube transmitting apparatus of the character described comprising in combination a variable neutralizing condenser, connected in series with a stationary condenser and means for bridging the said variable condenser in respect of continuous current voltage.
  • Neutralized tube transmitting apparatus of the character described comprising in combination a variable neutralizing condenser and a resistance adapted for bridging said variable neutralizing condenser.
  • Neutralized tube transmitting apparatus of the character described comprising in combination a variable neutralizing condenser, connected in series with a stationary condenser and a resistance adapted for bridging the said variable condenser.
