THOMAS SPOONER, OF EDGEWOOD PARK,
PENNSYLVANIA, ASSIGNOR TO WESTING- VANIA.
PARALLEL OPERATION ARC OSCILLATORS.
Application filed. February 14, 1921. Serial No. 444,823.
My invention relates to the joint operation of oscillation generators of the arc type, and .it has for an object to provide a system whereby the arcs may be connected in parallel across the direct-current supply circuit and in series in the oscillation circuit.
Another object of my invention is to provide a system for obtaining a high alternating-current voltage from a direct-current 1 source 01 low voltage.
Referring to the drawing for a more complete understanding of my invention the single figure is a diagrammatic view of apparatus and circuits representing one embodiment of my invention.
single source of direct current, indicated at l, is employed to supply a plurality of arc devices 2, 3, 4, which may be of the Poulsen type or of any other type suited to the generation of high-frequency currents.
The terminals of the are devices are all connected to the direct-current source, through choke coils 5, for the purpose of preventing the oscillating currents from flowing through the direct-current line. a
If desired, regulating resistances 6 may be included in series with each arc device for the purpose of regulating and stabilizing the arcs.
The are devices 2, 3, t are connected in series, through condensers 7, 8 and 9 and an inductance coil 10. One of said condensers is connected between each pair of the are devices in order to avoid short-circuiting the direct-current supply system. The series circuit, comprising the arcs 2, 8, 4:, condensers 7, 8 and 9 and inductance coil 10, is the oscillation circuit and may be tuned to any desired frequency.
The oscillating currents may be utilized in any desired manner. The drawing shows the coil 10 as being coupled to a secondary coil 11, which forms a portion of an antenna circuit 12, for radio transmission. The amplitude of the oscillating currents may be controlled by any modulating means (not shown) as is well known in the art.
It is possible that some of the choke coils 5 may be omitted, if desired, provided that no short-circuit is established for the oscillating currents. It is obvious, also, that as many arcs as desired may be connected in the manner illustrated in the drawing.
While I have shown a preferred form of my invention, I do not wish to be restricted thereto, but I desire that the appended claim shall be construed to cover such modifications and equivalents as will be readily apparent to those skilled in the art.
I claim as my invention:
In an oscillation-generator system, the combination with a single direct-current source, of a plurality of are devices connected in parallel therewith, a resonant oscillation circuit including said are devices, a plurality of condensers connected between the several are devices, and means for utilizing the reactance voltage developed in said circuit, said arcs, condensers and means being in series, choke coils included in the directcurrent leads of said are devices in such manner as to prevent the shortcircuiting of the oscillating current, and a ballast resistor individual to each of the are devices and connected in at least one of the leads thereof.
In testimony whereof, I have hereunto subscribed my name this 10th day of February 1921.
THOMAS SPOONER.
