Description

Main patent no. 395 describes a method for generating electromagnetic oscillations in that the oscillating circuit is shunted by a discharge tube, in which the distance between the electrolytes is less than the free path of the ions, and the oscillating circuit is connected to a self-induced magnetic field a discharge tube is placed to change the trajectory of the ions in order to ionize the gas and pass the current through the tube. The proposed invention is a modification of the method and consists in that the shunt circuit of the discharge tube with a distance between electrodes smaller than the free path of the ions is placed in a constant magnetic field.

In FIG. 1 shows a circuit for turning on a device for carrying out the proposed method; FIG. 2 is a view of the discharge tube; FIG. 3 and 4-longitudinal cuts of two different sizes for making tubes. The proposed method of generating electromagnetic oscillations does not require that the tube be placed in an alternating magnetic field of the frequency of the oscillations obtained, associated with the oscillatory circuit. It is enough to have some constant magnetic field, but the change of the electron trajectory will occur due to a change in the electrical voltage on the tube electrodes when oscillations already occur. A short change in electrical or magnetic voltage is enough to cause oscillations. Consistently with the discharge tube, in some cases, some watt or watt-free resistance is activated to create the correct oscillations.

A tube with two cylindrical (one inside the other) electrodes can be used to generate oscillations, with the inner electrode serving as the cathode, and the outer electrode 3 as the anode and vice versa;

The latter case requires a smaller magnetic field. When using a tube consisting of two electrodes, the distance between them is not constant in all parts of the tube’s working space, but changes accordingly so that the current buildup is not instantaneous, but has some degree of gradualness, the slope can be modulated in the desired direction, the oscillating current strength, for example, when such a tube is operated in a radiotelephone circuit (Fig. 1).

Such a tube with arbitrary distances between the electrodes can, for example, be in the form of a tube (Fig. 2) with two electrodes, of which one electrode is A-cylinder and the other is coaxial with it and located inside the first cone R or truncated cone . The modulation can be carried out by a magnetic field superimposed on a constant magnetic field. FIG. Figure 1 shows a similar layout. The discharge tube G is either shunted by a circuit L, C | connected with antenna A, or at short waves it is directly connected to antenna A ,. A permanent magnetic field, axial with the tube electrodes, is created by a coil L fed from a source of voltage E, Key K is intended to operate the tube in radiotelegraphic conditions. When key K is turned on, oscillations will occur (of course, for this to happen, there must be a definite relationship between the voltage feeding tube G — a magnetic

field and distance between the electrodes, as well as pressure in the tube).

The modulation of the generated oscillations is produced from the microphone L / through the transformer T by applying a modulated current to the direct current in the coil L, which creates a varying magnetic field that changes the generated oscillations in accordance with the current in the microphone circuit.

The discharge tube can also be considered as a modulated high frequency amplifier, and the high frequency can be different before amplification and after amplification. In order for the outer electrode, in this case, the cylinder, not to be shielded by the Foucault currents of a variable magnetic field arising in it, which must be in the space between the electrodes, such an external electrbd structure is expedient when along the generator of the cylinder there is a cut closed inside possibly also outside) by the blade B perpendicular to the radius

cylinder (Fig. 3 and 4).
