Abstract: 756,617. Voice immunity circuits. STANDARD TELEPHONES & CABLES, Ltd. June 11, 1954 [June 20, 1953], No. 17290/54. Class 40 (4). In a signal receiver which distinguishes between a pure signal frequency and spurious signals and comprises a differential relay having its windings S2, S1 separately energized over signal and guard circuits A, B, the signal circuit is aperiodically energized over a resistor R2 while the guard circuit is supplied through a filter comprising a condenser C1 arranged to resonate at the signal frequency in series with the mutual inductance of a transformer TR3, the resonant path constituting a short-circuit which disables the guard circuit when the signal frequency only is received. As shown, signals in a through circuit 4-5 are applied to both the signal and guard circuits over a transformer TR1, valve V and transformer TR2. A bias winding S3 of the relay is energized by the valve cathode current. Due to a shunt condenser C2, the signal circuit has the greater time constant. The rectified voltage in the signal circuit or alternatively the guard circuit is automatically regulated by an opposing voltage which is derived from a winding W2 of transformer TR1 and controlled by biased rectifiers G3.
