Abstract: 600,017. Thermionic modulation. BULL, C. S. Dec. 8, 1944, No. 24688. [Class 40 (v)] [Also in Group XL (a)] An apparatus for amplitude-modulating highfrequency oscillations comprises a resonator, fed with high-frequency energy, a beam of electrons passing through the resonator, the intensity of the electron beam being varied in accordance with the modulating signals, and means for abstracting amplitude-modulated high-frequency oscillations from the resonator. A hollow toroidal resonator 3 (Fig. 1), fed with high-frequency energy from oscillator 8, has a central gap 4 through which passes a beam of electrons emitted by a cathode 5 and collected by a target electrode 6. The target electrode is connected to resonator 3, which is maintained at a potential positive with respect to cathode 5. Resonator 3, tuned to the carrier frequency, is damped by the electron beam, the intensity of which is varied by modulating signals from source 10, applied between cathode 5 and resonator 3 by transformer 11, connected in series with a D.C. supply 15. The amplitudemodulated oscillations pass out of resonator 3 by an output coupling 12 which may be a wave guide or a concentric line. In another arrangement, Fig. 2, two resonators 3, 3a are fed in parallel from source 8, the electron beams passing through them being modulated in push-pull from source 10. The outputs from resonators 3 and 3a will be similar, but opposite in phase. The output of resonator 3a is fed into coaxial line 12a, which is arranged so that the output is delayed by half a period of the modulation frequency, which is nearly constant, with respect to the output from resonator 3, which is fed into line 12. The inner conductors of lines 12, 12a are connected by coupling loop 13. The phase of the high-frequency oscillations at the loop 13 is adjusted by a slidable section 14 of line 12. The output of one of two resonators connected as described may be utilized, and the output of the other dissipated in a resistive load. Specification 537,491 is referred to.

In a method of securing a hardened chain bushing 5 within a hole in a tempered chain bushing plate 3, Fig. 2, the surface of the bushing 5 is etched to decrease the mechanical stability of the surface prior to pressing the end of the bushing 5 into the hole to thereby effect removal of portions of the surface of the bushing 5 and plate 3, Fig. 4, so that the surfaces are in intimate metal-to-metal contact thus offering maximum resistance to separating forces. Bushing holes in bushing plates of carbon steel are burnished by forcing steel balls 0.004 inches oversize through the holes, the plates then being tumbled, cleaned and heat treated to a hardness R c  55 and tempered to R c  42-4.5 for toughness and resistance to fatigue. After further cleaning the plates are blued in a nitride bath at 600‹ F. to improve the appearance and to inhibit rust. Bushings are formed by bending 0.2% carbon steel flat to cylindrical form, then carbonizing and quenching in oil or water to provide a case hardness of R c  60 to a depth of 0.006 inch. After etching of the bushings, the latter are pressed into holes in bushing plates 3a, 3b, Fig. 3, with an interference fit of 0.003 inch, by a mandrel 10, the bushing plates and the bushings 5 being accommodated over guides 9.
