Patent GB-600675-A (GB)
Title: Power supply for sub-station amplifiers
IPC: H04M9/00
Filed: 1945-07-10
Abstract: 600,675. Substation amplifiers. AUTOPHON AKT.-GES. July 10, 1945, No. 17617. Convention date, March 9, 1944. [Class 40 (iv)] The power for a substation amplifier is provided from a central source of A.C. over the same pair which carries the speech currents, means being provided to prevent mutual interference between the two currents. A method of changing over the speaking direction is also provided. In one embodiment, power is supplied over the phantom of the speech wires aa, bb from the transformer TR at the central station S to the transformer ST at the substation TS, the centre tapped coils of both TR and ST being oppositely wound so that speech currents cannot enter the supply circuit and the primary inner coils of line transformer LU being wound so that power supply currents are not induced in the secondary coils. The filter F eliminates any stray power currents from the speech circuit. H.T. and L.T. for the amplifier are obtained from the secondary coils of ST via rectifiers GL. The amplifier transmits currents either from the line transformer LU or from the electro-acoustic transducer LM according to the setting of two-position switches W1, W2 which change over on successive energizations of coil W. The called and calling station switches W1, W2 are normally in the receive " position. When the calling station closes key T D.C. relay R energizes and in connecting power over wires a1, b1 to the called subscriber energizes his coil W to put the amplifier in the " transmit " condition (the called subscriber's key T being open). To change the speaking direction key T (which may be provided with a time regulating device) of the calling subscriber is opened sufficiently long to allow the sluggish relay R to release. During the release period, W at the calling station energizes to change over its calling direction. When R has released, W at the called station de-energizes and when R re-operates on the re-closure of T, W at the called station reenergizes to change over the speaking direction there. Transformer AT is provided with an armature which on de-energization at the end of a conversation sends switches W1, W2 back to the " receive position" if not already there. If the set is to be used in an automatic system, the time-switch T may be incorporated in a specially constructed dial. Separation of speech and power currents may be achieved by filters instead of by the above-described method or by a combination of both methods.

Abstract: 679,234. Cables. PYROTENAX, Ltd. June 29, 1951 [July 17, 1950], No. 17819/50. Class 36. A cable comprising one or more conducting cores separated from a metal sheath by pulverulent insulation is made by feeding powdered insulating material such as magnesia into the interior of the sheath around the core, and compacting it by relative movement between the sheath and a ram within it while circulating a conditioning gas through the part of the sheath to which the powder is fed. The gas used is one that will keep the insulation and the metal parts in good condition, as by removing or absorbing water, or removing oxygen, and it should have a high dielectric strength. A sheath tube C is mounted over ram F and within shroud D and held by a friction grip K in the manner described in Specification 669,779. The core rod C<SP>1</SP> is pushed up within the ram and its lower end secured to the bottom of tube C. Gas is circulated through the apparatus via pipes L, L<SP>1</SP> and dried magnesia is fed from canister H through the ram and into the sheath tube as described in Specification 669,780. The ram is pneumatically operated as described in Specification 669,781, and as the magnesia becomes more tightly compressed in the lower part of tube C the compressive thrust of the ram overcomes the resistance of the friction grip K, and the tube and core move with the ram for the rest of the downward stroke. The tube gradually moves down into well B until it is completely filled, when the gas circulation is stopped and the filled tube removed. The upper end of the tube is then sealed, and the cable is completed by a mechanical drawing down process.
