Abstract
121,500. British Thomson - Houston Co., (General Electric Co.). Nov. 14,1917. Frequency, changing.-An arrangement for increasing the frequency of an alternating-current consists of a source of alternating current connected to a circuit provided with means for distorting the wave-form of the current, thereby obtaining currents harmonic to the fundamental current, and a second circuit connected to the first circuit and resonant to the desired harmonic frequency. A third circuit similar to the second is provided if a further increase of frequency is desired. The first circuit is provided with means for stopping currents of the harmonic frequency, while the second circuit is provided with means for stopping currents of the fundamental frequency. In the arrangement shown in Fig. 1, an alternator 1 is connected to a circuit containing a tuning condenser 9 and a wave-deformer consisting of an inductance 3 partly energized by a direct current source 4. The terminals 5, 6 of this circuit are connected to a similar circuit containing a tuning condenser 23 and an inductance 11. The first circuit is provided with a circuit 7, 8 tuned to the frequency of the second circuit, thereby preventing the currents of the, second circuit from passing into the first circuit. The second circuit is provided with a circuit 13, 14 tuned to the frequency of the first circuit and with a circuit 15, 16 tuned to the frequency of the succeeding circuit, whereby currents of the frequencies of these circuits cannot pass into the second circuit.
