Title: Improvements relating to impulse sending arrangements for telephone systems
IPC: H04Q3/42
Filed: 1926-10-13
Abstract: 280,345. Siemens Bros. & Co., Ltd., and Humphries, H. E. Oct. 13, 1926. Addition to 230,291. Semi-automatic exchange systems.-Operators' senders of the kind described with reference to Fig. 5 of the parent Specification in which a fixed pause is provided between trains by causing the counting switch to move after each digit to a marked terminal, and in which no control relays are provided, are modified so that the control switch moves only two steps per digit instead of three and the same bank in the counting switch is used for stopping the digit as for stopping the pause. In one system, Fig. 2, the counting switch E races to normal after each digit and then advances more slowly [over fc, 32], starting the transmission of each digit when it has made 7 steps by connecting up the magnet F of the control switch which at the next break of the interrupter 32 removes the short-circuit from the interrupter 33 connected over battery to one wire of the trunk (the switch E continuing to move in a circuit, fb, 32). Wiper ea stops the digit by again connecting up magnet F, this time over the depressed key and wiper fa and wiper fb then makes a self interrupting circuit for magnet E. On reaching normal after the last digit the switch E makes a homing circuit for switch F wich near the end of its bank causes the cord to switch through as in the parent Specification. If a shorter pause is desirable between certain digits, marking wires for stopping the pause after different numbers of steps are taken to magnet F over the blank terminals of wiper fa, the single wire shown directly connected to magnet F being removed and the numerical marking wires being correspondingly shifted round the bank. In a modification, Fig. 3, the counting switch races over the remainder of the numerical terminals 1 - - 0 after each digit [in a circuit ec, fc, e], then takes alternate slow and quick steps to normal [in circuits ec, 32 and ec e] and then, provided the polarized relav F is not energized to indicate that the selector is not ready, advances one step [over p, fb] to start the next digit, which is sent as described in connection with Fig. 2. The arrangement shown is designed for ten digits but can be adapted for any smaller number by connecting wire dco to the terminal in bank fa following that corresponding to the last digit to be sent and multipling this and all subsequent fa terminals up to 20. On reaching their 12th terminals after this digit, wipers ea, eb complete a self interrupting circuit for switch F which races to its 21st terminals from which it is driven home [over fa, eb, 32] when the counter switch reaches normal. The trunk is bridged at ed independently of switch F during the rapid movement of the latter.

Filed: 1953-09-15
Abstract: 776,601. Automatic control systems. BRITISH THOMSON-HOUSTON CO., Ltd. Sept. 8, 1954 [Sept. 15, 1953], No. 25520/53. Class 38 (4). In an automatic control system, in which the output voltage of the servo-amplifier is limited, the primary error signal input to the amplifier is shunted by a non-linear resistor, e.g. a dry-plate rectifier. As described, the error signal is applied to a field 2 of an amplidyne supplying a motor 4. The error signal may comprise the difference between a reference voltage and that from the contact arm of a rheostat driven by the motor. The reversible output vcltage of the amplidyne is limited when it exceeds a reference voltage provided by a potentiometer 5, by the current flowing through a limiting field 3. Under limiting conditions the primary error signal may become large, and the input to the control field is limited by the non-linear shunting action of reversely connected rectifiers 10, 11. The amplidyne may be replaced by a magnetic amplifier.

Abstract: 356,924. Alternating current induction machines. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A.-(Assignees of Allgemeine Elektricitõts-Ges. ; 2, Friedrich Karl-Ufer, Berlin.) Aug. 27, 1930, No. 25585. [Class 35.] A split-phase induction motor has a capacity connected to the auxiliary phase through a transformer, and an additional voltage is produced at the terminals of the capacity by means of an additional transformer winding. As shown in the Figure, the condenser k is connected to the secondary winding e of a transformer r, the primary c of which is in series with the auxiliary phase winding b. The transformer also has an additional winding a<1> carrying the total motor current. The voltage at the terminals of the condenser accordingly varies with the motor current so that the current in the auxiliary phase also varies and the torque is produced equally by the main and auxiliary phases for all loads. The winding a<1> may carry the current of the main phase a only. An autotransformer may be employed. Specification 22852/97, [Class 37, Electricity, Measuring &c.], is referred to.
