Abstract : The patent relates to a hydrogen gas reservoir outside main discharging chamber of a transmitter-receiver tube which is allowed to leak hydrogen at a controlled rate through a palladium window in the envelope of the TR tube. An automatic pressure controlling unit is provided which comprises an electrical bridge circuit with a pressure sensing element in one arm of the bridge. An imbalance in the bridge circuit turns on a heater which raises the temperature of the palladium window which in turn lets hydrogen from the reservoir pass through it to recharge the TR tube.
