Description

As is well known, two electrical circuits (systems) that are connected in some way for their mutual influence on each other are called connected circuits. Usually, ohmic resistance, capacitance, or inductance serve as elements of communication. Accordingly, the types of communication known in electrical engineering (in particular, radio engineering) are named: a) galvanic c) capacitive, c) inductive and autotransformer.

The combined form of communication is a combination of elements included in the above types of communication.

Each of these types of communication has its own advantages and disadvantages.

The present invention is a fundamentally new type of connection between two electrical circuits or systems using a magnetic ion link.

It has been theoretically and experimentally established that the gaseous medium is a sufficient source of ions and electrons that will provide almost any current, while the gaseous medium retains full controllability by means of a magnetic field.

These circumstances and are the basis of the proposed invention, clarified FIG. 1 and 2 of the attached drawing. The invention relates to a device of two main elements: a self-induction coil L and a conventional two-electrode gas-luminous tube D located inside the self-induction coil b and, moreover, along its axis (Fig. 1).

One of the elements is connected to the primary circuit, the other to the secondary.

The operation of the device is as follows. When the coil is given a variable potential difference equal to or greater than the ignition potential of the gas tube, the gas (or vapors) that fills the latter is ionized. In this case, the ions under the influence of the magnetic field of the coil will periodically change direction, creating currents of the corresponding frequency in the circuit of the tube.

It should be assumed that this type of communication can first of all be used in transmitting radio engineering due to the simplicity of eliminating undesirable phenomena occurring in lamp transmitters, namely: c) parasitic self-excitation amplifier.

An example of the use of the described type of communication between two circuits is shown in the schematic diagram of the radio transmitter of FIG. 2

The subject matter of the invention.

A device for coupling two electric circuits, characterized in that an ion tube is placed inside a self-induction coil connected in one circuit, the electrodes of which are connected to the second circuit.
