KARL SCHMIDT, OF BEBLIN-SUDENDE, GERMANY, ASSIGNOR TO C. LORENZ AKTIEN- GESELLSCHAIT, OF BERLIN-TEMPELHOF, GERMANY.
HIGH-FREQUENCY TRANSFORMER.
Application filed January 17. 1925, Serial No. 3,099, and in Germany February 13, 1924.
The present invention relates to improvements in high frequency transforming systems and is directly more specifically to a new means for enhancing the efficiency obtained in the generation of muti le frequencies by means of frequency trans ormers. In certain known systems of this character the electrical connections are such that the hi h frequency generator is not arranged in t 'e oscillation circuit itself, but is coupled to a part of an induction coil.
My invention is directed to an improve-,
ment of.this arrangement, and I will now describe it in connection with the accompanying drawing.
In this schematic illustration H denotes the high frequency enerator which is coupled to a part of t e induction coil S. The primary circuit, comprising the selfinduction coil S, a variable self-induction L, the frequency -transformer T, and the tuning capacity C, is, as usual, tuned to the generator fre uency. To the terminals a and b of the windings there is connected, for example, the oscillating circuit L,, C, which is tuned to the higher frequency,
According to the present invention my improvement for enhancing the efliciency of frequency multiplying connections of the character referred .to is characterized in that a condenser is arranged in parallel with the self-induction to which the high frequency machine is coupled, and the oscillating circuit thus produced is tuned to a multiple of the primary frequency. This arrangement is shown in the diagram, wherein S represents the self-induction. coil and K my condenser in parallel therewith. By tuning this circuit to a multiple of the primary frequency, a substantially greater etliciency is obtained in the circuit a, 0,, L,, I. the harmonics occurring at the ends of the coil S and which are prejudicial to the frequencies desired, are taken up by the syntonizing condenser K, which renders the primary wave form more favorably constituted to obtain the frequencies desired. As aresult of this arrangement a greater out- This phenomenon is due to the fact that put, that is to say a greater efficiency, is obtained in the transformed current circuit.
What I claim is l. A frequency multiplication system comprising a high frequency generator, a frequency changing transformer having a winding connected in series with an oscillatory circuit, a primary circuit interposed between said winding and said generator, said primary circuit including a coupling inductance and a variable tuning inductance and capacity in series therewith, connections between a portion of said coupling inductance and said generator, and a condenser in shunt relation to said generator and said portion of said coupling unductance for facilitating the increase in frequency of energy delivered by said generator into said oscillatory circuit.
2. In a high frequency transforming system, a circuit for frequency multiplication comprising a high frequency generator, a frequency transformer having a primary circuit and an oscillating circuit, a self-induction coil in the primary circuit of the frequency transformer, a condenser arranged in parallel with the self-induction coil to which the high frequency generator is coupied and in the primary circuit of said frequency transformer, said oscillatory circuit being tuned to a multiple of the frequency of said primary circuit, said frequency change being facilitated by virtue of the interconnection of said condenser.
3. In a high frequency transforming system, a primary circuit including a self-induction coil, a high frequency generator coupled to a part of said coil :1 variable self-induction coil, a frequency transformer, and a tuning capacity connected in series with the whole of said self-induction coil, a secondary circuit tuned to a frequency higher than the frequency of said generator, and .a condcnser arranged inparallel with said selfinduction coil in said primary circuit for facilitatin the increase in frequency of the energy de ivered to said secondary circuit from said generator.
