Description

The present invention aims at obtaining, with one telephone coil, two pole extensions of two-sided action on measles, as well as the possibility of regulating the force of attraction of the cor to the pole extension.

In FIG. 1 depicts the proposed phone in a vertical section; FIG. 2-in horizontal.

Two pole extensions A and JBC are attached to one of the poles of the permanent magnet NS, the latter of which carries the telephone coil D. The extension A, which has the shape of a hollow body with a notch that runs from above to Izi and is located on the side opposite to Kory, covers the extension (FIG 2), as a result of which the passage of current through the coil D will change the magnetization of not only the BS extension, but also the extension L. One end of the core /, with a pin going to the membrane, enters the gap between the extensions A and BC, and the second rests directly on the extension the other pole. To change the force of attraction of a core to one or another extension, one of them, for example, BS

it becomes an integral part, whereby its part C can move towards the pole, keeping all the time the magnetic coupling with the fixed part B.

The subject of the patent.

1. A telephone characterized by the use of double pole extensions A and BS mounted on one of the poles of the N8 magnet, of which the BS extension carries the telephone coil D, and the extension A, without a coil, encompasses the BS extension and has the shape of a hollow body with a cutout extending from its top to bottom and located on the side remote from the core / C, one end of which enters the gap between the extensions A and BS, and the other end rests directly on the extension of the other pole,

2. In the application of the pole extension described in item 1 of the telephone, one part of which is fixed motionless on the magnet, and the other part is arranged mobile, in order to change its length, from the cor.
