Le brevet principal concerne un montage destiné à transmettre des oscillations électriques, comprenant au moins un tube à décharge .nodule, qui comporte, outre l'électrode de sortie, au moins une autre electrode parcourue par du courant. Le .montage qui fait l'objet du brevet principal est caractérisé par le fait que l'on preleve du circuit de l'électrode parcourue par du courant une tension de souffle en corrélation avec les fluctuations accidentelles de la répartition du courant entre l'électrode de sortie et l'electrode parcourue par du courant, tension de souffle qui :nodu&#65533;e le courant de sortie du tube avec une phase et une intensité telles que le courant de souffle provoque dans le circuit de sortie par les fluctuations spécifiées suit entière. lent ou pratiquement entièrement supprimé.

The main patent relates to an assembly intended to transmit electrical oscillations, comprising at least one discharge tube .nodule, which comprises, in addition to the output electrode, at least one other electrode traversed by current. The assembly which is the subject of the main patent is characterized by the fact that one takes from the circuit of the electrode traversed by current a blast voltage in correlation with the accidental fluctuations in the distribution of the current between the electrode output and the electrode traversed by current, blast voltage which: knots the output current of the tube with a phase and intensity such that the blast current causes in the output circuit by the specified fluctuations follows whole. slow or almost completely suppressed.

Claims

t. It goes without saying that, in the case considered, this effect is nil. Slowly desirable, and it gives that it is then impossible to obtain

The braking grid 5 is very weak.

<EMI ID = 14.1> transmit, while the distance between the electrode by-

between the output electrode and the previous electrode are traversed in less than one de.ni-period, this assembly may also have the particularity that the electrode traversed by current is separated from the output electrode by a single electrode not traversed by current, and that the penetration of the output electrode through the electrode not traversed by current is very low.

2.- Electron tube intended for assembly as specified under 1, and comprising a cathode and an anode separated by three grids, characterized in that the distance between the second grid and the third is large compared to

at the distances between the first and the second grid and between the third grid and the anode and that the penetration of the anode through the third grid is very low.
