  • the trigger tubes On receiving a signal, the trigger tubes are selectively ignited and their arcs held through the' plate resistors and finally the'relay contacts are closed and the plate circuits extended through the'respective control magnets.

  • Fig. 2 is a diagram of a circuit employing six trigger tubes of the type shown in Fig. 1.
  • Fig. 3 is a diagram of a'combinational code signal to which the circuit is designed to respond.
  • the trigger tube as shown in Fig. 1, is similar to a thyratron oi the type known as a 2050. It has an anode II, a cathode II, a control grid l2 and a shield grid it, all of standard construction.
  • the shield grid is a box-like structure enclosing the other electrodes and having a partition H between the anode and control grid with a window resistances l-G.
  • an auxiliary anode I! is inserted in the compartment con-. taining the main anode l0 and is shown in the drawing as a. small round rod located between the partition I4 and the anode Ill.
  • the electrode structure is enclosed in an envelope H which contains a gas, such as mercury vapor, or one of the inert gases, at a low pressure.
  • the circuit shown in Fig. 2 is designed for the reception of -signals of the kind shown in Fig. 3, consisting of a start signal ST'I, six code elements i-G, and a stop signal STP.
  • the signal shown in Fig. 3 is the combination 5.
  • the stop signal and the code elements 2, 4 and 5 are represented by marking conditions while the signal elements I, 3 and 8 and the start signal are represented by spacing conditions.
  • the circuit comprises six gaseous trigger tubes Gl-Gi of the kind shown in Fig. 1.
  • the cathodes of these tubes are connected by a wire 20 to the negative end of a voltage divider comprising
  • the voltage divider is connected across a suitable D. C. voltage supply represented by +0. I
  • the control grids'of the tubes Gl-G6 are connected through respective grid resistors 2
  • the shield grids are connected through grid resistors 23, a wire 24, a resistance 25, and a wire 26 to a point 2'! on the voltage divider l-G.
  • the auxiliary anodes are connected through anode resistors 28, wire 2!, normally closed contacts R2a of relay R2, and wire 30 to the positive end of the voltage divider l-G.
  • the main anodes are connected through the respective control magnets Ml-MB to a wire 3
  • the control grids of normally have a negative suilicient to prevent even if a positive bias is applied to. the shield grids.
  • the shield grids In the normal condition of the circuit, the shield grids have a positive end of the voltage bias and this bias is 2
  • the circuit or each grid extends through the secondary .winding of the transformer associated with the preceding tube in the sequence, the circuit of the grid of the tube VI extending through a secondary winding of a transformer T0 associated with the vacuum tube V0.
  • the anode of the latter tube is connected through the primary winding of the transformer T0 and wire 30 to the positive end of the voltage divider I6, while its cathode is connected through a wire 45 to a point 46 on said voltage divider.
  • the grid of the tube V1 is connected through the secondary winding of transformer T6 and the wire 41 to a point 48 on the voltage divider l-B.
  • the anode of this tube is connected through an anode resistor 49 to wire 42 and thereby to the point 43 of the voltage divider I5.'
  • the grid of the tube VII is connected through a resistance 5
  • the tube V0 is rendered non-conductive, in a manner to be described presently, current ceases to flow in the primary winding of the transformer T0 and the field of this transformer collapses. This induces a voltage in the secondary winding which lifts the potential of the grid of the tube VI to a point which renders the latter tube conductive.
  • grid current flows in the tube- VI retarding the collapse of the field in the transformer T0 for a definite time.
  • the tube V0 is in a conductive state and current is flowing in the primary winding of the transformer T0.
  • the start of the sweep is controlled by a start tube V8, the cathode of which is connected by a wire 55 to the negative end of the resistance I, the plate of which is connected through a resistance 56, the primary winding of transformer TST, and wire 30, to the positive end of the voltage divider I6, and the grid of which is connected through a grid resistor 51, wire 24, resistance 25, and wire 25 to the point 21 of the voltage divider I6.
  • the tube V8 is therefore normally conductive.
  • the delay circuit 50, BI is designed fora delay of one-half signal baud, so that the sweep begins at the mid-point of the start signal.
  • the positive voltage wave applied from the transformer TI to the control grid of the trigger tube GI finds a spacing signal condition (slgnal element I) across the resistance 25, which depresses the potential on the shield grids of the tubes Gl-G5 and prevents the tube GI from being ignited.
  • the positive voltage wave from the transformer T2 to the control grid of the tube G2 finds a marking signal condition (signal element 2) which causes no voltage drop across the resistance 25, permitting the potential on the shield grids of the tubes Gl-GB to rise.
  • the tube G2 is accordingly ignited, the are being held through a circuit extending from-the positive end f the voltage divider l-6, through wire 30, normally closed contact R2a, wire 29, anode resistor 28 of the tube G2, the auxiliary anode of this tube, across to the cathode and, by way of wire 20, to the negative end of the voltage divider l-6.
  • the tubes G3 and G6 are not ignited, while the tubes G4 and G5 are ignited.
  • the positive voltage wave transmitted from the transformer T5 also extends through a wire 10 and condenser H to the control grid of a gas tube G1.
  • the cathode and shield grid of this tube are connected through wire to the negative end of the voltage divider I--6, while its anode is connected through the coil of relay RI and wire to the positive end of the voltage divider.
  • the positive voltage wave transmitted to the control grid of the tube ignites the tube and the relay RI is energized.
  • the field of the transformer T6 which was last energized, collapses and a positive potential is applied to the grid of the tube V1 which becomes conductive for a period determined by the position or the point 48 on the voltage divider
  • a negative voltage wave is transmitted from the plate or the tube V1, through wire 15 and condenser 16 to the grid of the tube V9, cutting oi! this tube and thereby deionizing the tube G9.
  • the tube V0 becomes conductive again and the sweep circuit is restored to standby condition.
