    摘要： A transmission coil system has a first and a second transmission coil in which the first transmission coil is connectable to a stimulation unit, and the second transmission coil can be used as part of a resonant circuit which can be stimulated to resonate, and having a coil core for two transmission coils that are loosely magnetically coupled to one another in that the two transmission coils are wound alongside one another on the coil core. Stimulation of the first transmission coil leads to a resonant increase in the applied voltage in the second transmission coil, and thus to an amplified transmission power. This may be used, for example, for remote control of the hearing aid, since, for example, it allows 200 bits/s data transmission over several meters from a low-voltage source.

    摘要： An output transformer, especially useful to couple a balanced output stage to an unbalanced load, employs first and second primary winding halves, which have their "center taps" physically offset, and wherein the windings are wound coextensively for some but not all of their length. The secondary winding is wound coextensively with one or the other of the two primary halves, thereby improving the coupling and reducing leakage inductance and also reducing the interlayer volt amperes and thus reducing interlayer capacitance.

    摘要： A fluxbucking line transformer is disclosed in which fluxbucking primary windings in the line transformer compensate for the DC flux generated by the passing of DC currents by the primary windings. No feed-back circuitry is required for sensing the DC components of the magnetic field in the transformer core or to sense the DC current through the transformer to provide adjustment of the fluxbucking current. The disclosed transformer circuit is a bridge configuration which cancels the DC flux independently in separate primary windings, and is advantageously employed in telephone line circuits in which large DC currents are passed through the line transformer while smaller ac signals are coupled to the secondary without distortion of the ac signals due to saturation of the transformer core.

    摘要： A coupling transformer for networks with superimposed audio frequency voltage, especially for ripple control systems, with primary and secondary windings rigidly coupled with each other and arranged about an iron core; the primary and secondary windings surround one another coaxially and are separated and insulated from one another by a cast resin insulation, whereby only one of the two windings is embedded in the cast resin insulation while the other, freely accessible winding coaxially surrounds the iron core constructed as rod-type core under formation of at least one cooling channel; an electric shield is additionally provided between the two windings.
