Description

May 9, 1933. I M. OSNOS GLOW LAMP CIRCUIT Filed June 4, 1931 INVENTOR Mf/VDE 05/v05 BY 42 ATI'TORNEY Patented May 9, 1933 UNITED STATES PATENT OFFICE HENDEL OSNOS, OF BERLIN, GERMANY, ASSIGNOR T TELEFUNKEN GESELLSCHAFT FUR DRAHTLOSE TELEGRAPEIZE M. H., OF BERLIN, GERMANY, A CORPORATION OF GERMANY GLOW LAMP CIRCUIT Application filed June 4, 1931, Serial No.
The parallel connection of gas-discharge vessels, especially glow-discharge or gaseousconduction tubes, is attended with practical difliculties 0n the ground that these apparatus, for the customary potentials, exhibit a negative resistance characteristic, so that, if one of the lamps happens to take more current than the other or others, there arises the danger of its taking more and more current, while the current in the other lamp or lamps decreases more and more. Hence, there exists not only a danger of the E. M. F. source being short-circuited, but also that of irregular and non-uniform luminescence of the diii'erent lamps.
It has therefore been suggested to make the discharge gap of a lamp as much longer as possible so that such a lamp would be the equivalent of a plurality of series connected lamps having normal discharge gaps. How-. ever, this in turn presupposes and requires the provision of a higher potential which also has certain drawbacks.
According to this invention as illustrated, for example, by the accompanying drawing paralleling of lamps of the gaseous-conduction type or similar devices having a negative resistance characteristic is made possible in practice by arranging each lamp G, or a group of such lamps being comprised of a limited number of lamps being connected in series, in parallel relation to part of a voltage divider consisting of an inductance L and a capacity C where each is tuned to the supply frequency.
It can be found that in such a case the cur-. rent of each lamp is wholly or almost whol- 1y independent of the resistance of this lamp.
The invention is useful alsofor other similar devices, for instance, in paralleling alternating current supplied rectifiers or vacuum tubes of the ionic or electronic type, etc.
Having now described my invention, what 542,063, and in Germany May 16, 1930.
I claim and desire to secure by Letters Patent is the following:
1. A system for arranging a plurality of gaseous-discharge devices in parallel comprising anenergy source, a plurality of independent combinations of series-connected inductance and capacity devices connected across the source, and a gaseous-discharge device connected across the capacity portion of each independent combination of seriesconnected inductance and capacity elements.
A system for arranging a plurality of glow discharge devices in parallel compris ing a source of energy, a plurality of seriesconnected inductance and capacity elements connected across said source, and a flow discharge device shunting each ofi said capacity elements.
3. In a system for arranging a plurality of glow discharge devices in parallel, a source of energy, a plurality of series-connected inductance and capacity elements tuned to the frequency of said source shunting said source and arranged in parallel with respect to each other, and a glow discharge device connected in parallel with each of said capacity elements.
4:. A system for arranging a plurality of gaseous-discharge devices in parallel comprising an alternating current energy source, a plurality of series-connected independent combination of reactance elements, each combination being connected in parallel with the source, and a gaseous-discharge device connected across a portion of each of said seriesconnected reactance elements of each comb-ination.
5. A system for arranging a plurality of potential operated discharge devices each containing an inert gas in parallel comprising a source of alternating current energy, a plurality of series-connected combination of inductance and capacity elements, each of said combinations being connected in parallel with the source, and a potential operated space discharge device shuntingthe capacity e ement of each combination.
6. In a system for arranging a plurality of gaseous discharge devices in parallel, a source of alternating current energy, a plurality of series-connected combinations of reactance elements tuned to the frequency of said source and each arranged in parallel with the source and each series combination being arranged in parallel with respect to each other, and a gaseous discharge device connected in parallel with a portion of each of said series combinations.
