JOSEPH BETHENOD,
OF PARIS, FRANCE.
HIGHJTBEQUENCJY SIGNALING SYSTEM.
Application filed May 6,
To all whom it may concern:
Be it known that I, Josnrrr Bnrrrnnon, a citizen of the Republic of France, and a resident of Paris, France, have invented certain new and useful Improvements in High- Frequency Signaling Systems, of which the following is a specification, accompanied by drawings.
The object of the present invention is to provide arrangements for increasing and regulating the synchronizing connection of high frequency alternators connected in parallel.
The new circuit arrangement to be hereinafter described has two important advantages:
1. The condensers are only traversed by the synchronizing current, whereby their work is materially reduced.
2. The adjustment of the synchronizing connection may be effected independently of the adjustment of the useful individual load of the alternator-s. As a result of this, the adjustment is easily accomplished because it becomes independent of the usual placing in resonance of the charging circuit comprising the connected alternators and the external apparatus (antennae, etc.)
In the single figure of the drawing a circuit arrangement is shown in accordance with the above. The high frequency alternators 1 and 2 are assumed directly to feed the antenna One of the poles of each of the alternators is connected to the ground 4 and the two alternators are interconnected through the agency of an inductance coil 5, the central point of which is connected with the antenna The terminals of this coil are short-circuited through the coupling condenser 6, the latter being preferably connected in series with a tuning coil 7.
It will be therefore readily seen that the condenser is traversed only by the synchonizing current, and this current may be tuned to the most suitable value by means of the coil 7. On the other hand, if. the magnetic leakage between the two sections of the coil 5 is materially reduced, the ensemble comprising 5 and 6 has practically no appreciable influence on the tuning of the useful current supplied to the antenna 3, the ampere turns corresponding to this current being practically zero. However, the coil 5 may be replaced by a system of two inductances or two capacities connected in series, the

junction point being in turn connected to the antenna But in this case, the system has a certain function in the tuning of the useful output current. However, the tuning of the synchronizing current may be inclegendently eifected by means of th ensemble,
Obviously, the above described circuit arrangements may be variously modified and more particularly, may be adapted for systems in which the alternator is not connected directly to the antenna as shown in the system herein described, but through a transformer. The arrangement may also be applied to systems in which a plurality of al ternators are used.
Having described my invention, what I claim is:
1. The combination of a radiating unit, a plurality of parallel high frequency generators for supplying said radiating unit and a synchronizing connection between said generators comprising a pair of impedances in series shunted bya condenser, said radiating unit being connected to the junction point of said imnedances.
2. The combination of a radiating unit, a pluralitv of parallel high frequency generators for supplying said radiating unit and a synchronizing connection between said enerators comprising a pair of impedanccs in series shunted by a condenser, and an inductance in series, said radiating unit being connected to the junction point of said impedances.
3, The combination of a radiating unit, a plurality of parallel high frequency generators for supplying said radiating unit and a synchronizing connection between said generatorscomprisiug a pair of impedances in series shunted by a condenser, and a variable inductance in seriesx said radiating unit being connected to the junction point of said impedances.
4. The combination of a radiating unit, a plurality of parallel high frequency generators for supplying said radiating unit and a synchronizing connection between said gencraters comprising an inductance shunted by a condenser, said radiating unit being connected to an intermediate point on said inductance.
5. The combination of a radiating unit, a pluralit of parallel high frequency generators for supplying said radiating unit and a synchronizing connection between said generators comprising an. inductance shunted by a condenser between said generators, said radiating unit being connected to the middle of said inductance.
6. The combination of a radiating unit, a plurality of parallel high frequency generators for suoplying said radiating unit and a synchronizing connection between said gen- 10 erators comprising an inductance shunted by a condenser and an inductance in series be tween said generators, said radiating unit being connected to the middle of said inductance.
7. The combination of a radiating unit, a plurality of parallel high frequency generators for supplyingsaid radiating unit, said generators being c'rounded at one terminal, and a synchronizing connection between the other terminals coniorising an inductance shunted by'a capacity, said radiating unit being connected to a middle point of said in ductance.
