Title: Improvements in or relating to cable telegraphy
IPC: H04L5/06
Filed: 1920-11-18
Abstract: 179,574. Potter, E., (Pernot, F. E., and Rich, L. J.). Nov. 18, 1920. Diplex, duplex, and quadruplex telegraphs.- Relates to submarine and like cable systems in which alternating-current signals alone, or both alternating and direct current signals, can be simultaneously sent and received, and consists (1) in the use of inductive coils or a transformer 6 oppositely wound at 4 and 5 with coils located respectively in the two arms of the bridge so as. to offer a high impedance to incoming alternating- current signals, whereby they are fully impressed upon the receiving apparatus, whilst at the same time offering a low impedance to outgoing signals, and (2) in means for compensating for inexact balance between the artificial line and the .cable, when using alternating currents, by taking a fraction of the power from the alternator E and applying it through the coils 12 - - 15 and 18 - - 21 to the amplifier A. Frequency-selecting means of the type described in Specification 180,349, [Class 38 (ii), Electric currents, Converting &c.], may also be interposed between the amplifier A and telephone T to assist in completely eliminating telephone noises due to unbalance. Direct-current signals from the key 7 and battery 8 are shielded from the earth 24 by a condenser 10, and pass to line 1 without affecting the galvanometer G. The windings 4 and 5, being in opposite directions, neutralize each other and offer no impedance to such currents. Alternating-current signals from the key 11 are shielded from the earth 23 by an impedance coil 9. They do not affect the galvanometer G, mainly because this is largely insensitive to highfrequency currents, but also because of the bridge system. Practically no impedance is offered by the coils 4, 5 which are wound in opposition. In order to compensate for imperfect balancing between the lines 1 and 22, the current from the source E is split so that one part traverses an inductance path 17 and the other part a capacity path 16. The voltages of the two components are consequently out of phase, and these are applied through transformers 12 - - 15, and adjustablycoupled coils 18 - - 21 to the amplifier A in such a way as to eliminate any telephone noise from the outgoing signals. Incoming direct-current signals actuate the galvanometer G, but do not affect the amplifier A to any appreciable extent. Incoming alternating-current signals pass through the amplifier to the telephone in the usual manner. The iron cone 6 prevents any large portion of this signal energy from being lost through the galvanometer because to such currents the coils 4 and 5 are cumulative in effect and oppose a large impedance.

Title: Improvements in or relating to regulating mechanism for electrical installations
IPC: H02P9/24
Filed: 1919-12-29
Abstract: 137,304. Soc. Anon. des Etablissements L. BlÚriot. Dec. 28, 1918, [Convention date]. Regulators, automatic systems for.-In systems for automatically regulating direct-current dynamos by means of electro-magnets which insert resistance and are themselves automatically " compensated," i.e. are arranged to receive less current after having attracted their armatures, further means, either manual or automatic, are provided for the purpose of varying the amount of such compensation according to varying conditions of the circuits. Fig. 1 shows one arrangement. A shunt-wound dynamo a is regulated by an electro-magnet c which is capable of attracting an armature c<1> and thus inserting a resistance b in the circuit of the shunt-winding. The electromagnet is connected to a point b<0> in the resistance b, so that part of this resistance reduces the holding-on current. According to the invention, the last-named point of connexion is movable along the resistance b under the influence of a solenoid h energized by windings taken from the circuits to be controlled, such as the circuits of lamps or batteries. Alternatively, the point b<0> may be shifted by hand. Another arrangement, shown in Fig. 5, comprises a dynamo of the Rosenberg type having two short-circuited brushes c and a field winding a<1> as described in Specification 130,575, this being regulated by an electro-magnet c and resistances b, b', f. Both terminals of the electro-magnet c are connected to movable points along the resistances b and f, and the desired movement is effected manually or automatically. The Specification describes another arrangement comprising four regulating resistances functioning as arms of a wheatstone bridge and two electro-magnets, both of which are connected to movable points along these resistances.

Abstract: 380,652. Electric clocks. ELEKTROZEIT AKT.-GES., 136, Mainzerlandstrasse, Frankfort-on-Main, Germany.-(Assignees of Schonberg, G. ; 17, Munstererstrasse, H÷chst-on-Main, Germany.) Nov. 25, 1931, No. 32679. Convention date, Nov. 25, 1930. [Class 139.] Synchronizing.-In a synchronizing clock system, the operating line from the master Z to the self-contained secondaries R1, R3 is divided into sections L1, L2, L3, the secondaries at the dividing points R2, R4 being provided with switches and local batteries and acting as intermediate control clocks, so that the system is synchronized section by section, each clock R2, R4 synchronizing the following section. Means are provided at the master for automatically recording the synchronizations. Contacts z1, K, K1 close about every fourth minute and at the secondary R1 a contact r11 closes just before the synchronizing time. Contacts r11, r21, r31, r41 are closed at different times once a day. This gives a circuit B, z2, z1, relay R, L1, w1, r12, r11 and earth, so that relay R closes contact r to energize the recording magnet Rg from battery LB. At the same time a holding relay H closes contacts h to short-circuit relay R, de-energizing the recording magnet Rg. The clocks such as R1 are adjusted to gain slightly, so that immediately before synchronization, contact r12 is lowered to energize a relay R1 which stops the clock. At the synchronization moment, contact z2 is opened at the master, relay R1 is de-energized and the secondary clock restarts on time ; contacts r12, r11 returning to the positions shown. The intermediate control clock at the junction of sections L1, L2 is similarly synchronized. In addition, a contact K at clock R2 is closed about thirty seconds before the synchronizing moment and opened exactly at that moment to pass the synchronizing circuit on to section L2 (clock R3). This also energizes a relay U which connects line L1 to earth so that relays R and Rg are again energized. Similarly a contact K1 at the second intermediate control clock R4 extends the synchronization on to the third section L3.
