llgnor to Radio Corporation of America, acorporation of Delaware A plication July 14, 1930, Serial N0. 487,831 19 Claims. (Cl. 250-38) This invention has asits main object the provision of new and useful methods of and means for the production of electrical alternating oscillations. Broadly, it is an object of this inp vention to produce an electronic discharge or are and, by producing relative motion betweenv the discharge and a conductor, to induce potentials in the conductor by the action of the fields about the are or discharge.
More specifically, it is an object of this invention to provide an arc and to provide for the rotation of the same by subjecting it to a magnetic field. Consequently by having one or more conductors in the path of the fields associ- 1g ated with the arc, electrical oscillations will be set up in the conductors.
Still a further object of this invention is to produce oscillations by shock exciting a tuned circult with a traveling or rotating arc.
20 Still another object of this invention is to pro-v vide for the generation of-polyphase currents with a rotating arc.
Another object of the present invention is to provide for the modulation and transmission of as the oscillations produced in the manner hereinbefore outlined.
Referring to the accompanying drawing which is only illustrative of the present invention,
Figures 1 and 2-are right angled views, partly 80 in section, of apparatus for producing a rotating electronic discharge in the form of an arc, the arc inducing currents in a nearby conductor,
' Figure 3 discloses apparatus for utilizing a moving arc to shock excites tuned circuit,
85 Figure 4 is a preferred'arrangement of electrodes for shock exciting a tuned circuit,
Figure 5 is a modification of Figure 3 for shock exciting a tuned circuit,
Figure 8 indicates apparatus for modulatin 40 oscillations produced in accordance with the pres ent invention, and
Figure '1 indicates, diagrammatically apparatus forobtaining, according to the present invention, polyphase currents.
45 Turning to Figure 1, by the application of a suitable potential to leads 2, an arc may be set up between an inner circular electrode 4 and an outer annular electrode 0, which electrodes together with conductors t are mounted withinan 50 hermetically sealed container filled with a suitable gas. For the sake of simplicity, the container or envelope has been shown by dotted lines. The container should contain a gas to start an arc, and the gas should be rarified in order to so reduce windage. By means of a solenoid ll,
' over a suitable antenna 42. To improve action preferably placed outside of the container, a magnetic field may be set up in a direction traversing the longitudinal axis of are or electronic dischar e 1!.
Since the are represents a current, application 5 of a magnetic field in the direction shown will cause it to rotate between the inner electrode 4 and the outer electrode 6 which may be supported, as shown in Figure 2, by means of supports I4 and annular insulator l6. Rotation of the are past 0 the pick-up wires 8, joined at their outer extremities as shown by the single conductors IE, will induce potentials therein at a. frequency determined by the pressure of the gas, the strength of the field, and the potential applied to the leads 2.
The oscillations generated may be radiated from the conductors IE or they may be fed into a land line or the like for transmission. Modulation may be accomplished by the application of amplified complex currents through a transformer 20 to the field coils l0, and/or by application of keyed modulating alternating energy through a transformer 22 to the electrodes. In the event that both modulations are to be simultaneously 25 transmitted, the frequency of source 24 should be chosen above the audible range of frequencies, or, beyond the range of frequencies supplied by transformer 20.
The output of the oscillator modulated as de scribed will be frequency modulated energy. In order to obtain, if desired, amplitude modulated energy, the arrangement shown in Figure 6 may be resorted to wherein the oscillator has been diagrammatically indicated by circle 26. The output of the oscillator is fed serially through a resistance in the form of the internal resistance of a thermionic tube 28 varied according to modulation potentials applied to the control electrode 3i! thereof through a transformer 32. Accord- 4o ingly, oscillations of varying amplitude are fed, through a blocking condenser 33 and lead 34, to an amplifier I8 and then, if desired, amplified and transmitted. If found desirable, in addition, a frequency multiplier 38 and a further amplifier 40 may be provided for radiation or transmission of the device, a tuned circuit I00 may be connected as shown ahead of amplifier as.
The rotating arc may also be utilized for generation of oscillations by shock exciting a tuned circuit. Thus, for example, in Figure 3, a tuned circuit 44 is connected to outer terminals or electrodes 46, ll about the center circular electrode ll, through the supports I4 and conductors ll,
