Description
Feb. 24, 1931. GOEBELER 1,794,288
HIGH FREQUENCY APPARATUS Filed June '7, 1927 67220022 202: E ave e/er UNITED STATES PATENT OFFICE EBERH ARDT'GOEBELER, OF JENA, GERMANY nron-rnnemmcr APPARATUS Application filed June 7, 1927, Serial No. 197,165, and in Germany June 9, 1926.
My invention relates to improvements in the method of and system for preventing disturbances of radio transmission by high-frequency apparatus, and more partlcularly by unipolar high-frequency apparatus for cosmetic and medical'purposes. The main elements of the said high-frequency apparatus consist of an interrupter ada ted to be connected to the supply system, a igh-frequency transformer, and an electrode connected to the high-voltage terminal of the secondary of said high-frequency transformer.
In high-frequency apparatus of this type electro-magnetic oscillations are generated, which are adapted to cause disturbances in receiving stations of radio systems. The strong emission of electric waves causing disturbances even in radio apparatus located large distances away from the high-frequency apparatus is explained by the fact that the system supplying the electric energy to the high-frequency apparatus and having strong emitting property is a part of an open oscillation circuit, which is balanced by the secondary of the high-frequency transformer, the electrode and theperson using the highfrequency apparatus.
In my improved system the said disturbances are avoided by transforming the open oscillation system of the unipolar high-frequencyapparatus by means of a high-frequency short-circuit into a closed system which is not able to emit oscillations.
For the purpose of explaining the invention and example embodying the same has been shown in the accompanying drawing illustrating the high-frequency apparatus 1n a diagrammatical way and partly in section.
In the said drawing the character 1 indicates the conductors of the supply system,
which conductors include the coil 2 of an interrupter 3. The primary high-frequency circuit 6 is connected at 4 and 5, and it includes a condenser 7 and the primary 8 of a high-frequency transformer the secondary 9 of which is connected to a metallic sleeve 10 adapted to receive an electrode 11. The 1nterrupter 3 and the condenser 7 are confined within a casing 12, and the high-frequency transformer 8, 9 is disposed wlthin a separate casing 13 of insulating material constructed so as to provide a handle. The conductors 6, ,6 may be combined into a cable passed into the handle 13 at one end thereof, while the sleeve 10 is provided at the opposite end of the said handle. The conductors 1 may also be combined into a cable passed through the wall of the casing 12.
The casing 13 carries a metal ring 14 open at 15 to prevent its forming a short circuited coil. The metal ring 14 is connected by a lead 16 including a condenser 17 located within the casing 12 with one of the conductors 1 of the supply system. The electrode 11 and a person A which may make contact with the said electrode, and the high-frequency 8, 9, and more particularly the secondary thereof, provide one end of an open oscillating highfrequency systemrthe other end of which is provided by the supply system 1. The aforesaid disturbing electrical waves are emitted from the said open oscillation system. By means of the ring 14 connected through the lead 16 and the condenser 17 to the supply system the said open highly emitting system 75 can be transformed in practical use into a closed system having practically no emission of electrical waves. This is done by a person A treating itself by means of the apparatus and applying the electrode 11 to the part of the body to be treated and further holding the handle 13 and consequently touching the ring 14 carried thereby, thus closing the highfrequency circuit 6, 8, 9, 10, 11, A, 14, 16, 17, 1, 4, 6. v
If the person A holding the handle 13 and touching the ring 14 treats another person B, also the person B must make contact with the lead 16 for including the same into the closed high frequency circuit. For this purpose I provide a subsidiary lead 18 connected to the ring 14 and carrying an electrode 19 which may be brought into contact with the person B. The lead 18 may also be connected to the lead 16 in any point between ring 14 and condenser 17 or it may be connected to one of the conductors 1 with interposition of a special condenser.
I claim:

A high frequency apparatus, comprisaninterru terconnectedtoasu lying :d nductor for electric energy, a 111 quency transformer connected with aaid interru ter, an electrode connected with the 1 5, secon ary of said transformer, a subsidiary electrode, and a lead including a condenser and connecting said subsidiary electrode with said siippllyin conductor.
