Title: Improvements in electric modulators employing electron discharge tubes
IPC: H03C3/06
Filed: 1948-02-27
Abstract: 653,062. Cathode-ray tubes. STANDARD TELEPHONES & CABLES, Ltd. Feb. 27, 1948, No. 6075. Convention date, March 1, 1947. [Class 39 (i)] [Also in Groups XL (b) and XL (c)] The high-frequency circuit wave is phasemodulated by using the carrier to modulate an electron beam, and the modulating signal is used to deflect the beam to and fro along a two-conductor transmission line. A carrierwave generator 17 is connected between the indirectly-heated cathode 2 and a plane or curved grid 3. The beam is focused on to the line 4 by adjustment of the field between the poles N, S and of the positive potential on the deflecting plates 5 and the line 4 from the source 15. The line 4 is several wavelengths long, and comprises a slotted metal cylinder, or a slotted metal film 7 on a ceramic rod 9, which is secured at one end to a terminal band 11, and is coated with a baked ceramic layer to separate it from the helix 8, the insulation on which is removed by grinding along that generator which is scanned by the beam. The helix and the terminals may be sintered in position. Resistances 13, 14 each equal to the impedance of the line 4 are connected to the ends of the helix and the output 16 is taken from the ends by resistance 14. The undeflected beam impinges on the mid-point of the line 4 and the application of modulating signals from the source 18 to the deflecting plates 5 causes the beam, in conjunction with the magnetic field, to vibrate along the line 4 about its midpoint to produce therein a phase modulated carrier signal. For frequency modulation, it is arranged that the phase shift for a given signal is made inversely proportional to the signal frequency by the use of the resistance 19 and inductance 20. Dimensions of the line for use with a carrier wave of 10 m.c. per second are specified.
