Patent GB-1446002-A (GB)
Title: Converters
IPC: H02M7/515
Filed: 1973-08-09
Abstract: 1446002 Inverting; control of A.C. motors ROBERT BOSCH GmbH 9 Aug 1973 [10 Aug 1972] 37876/73 Headings H2F and H2J In a multi-phase inverter, each phase RST is connected to a positive lead 90 by way of a thyristor 50, 60, 70 forming part of a first group and to a negative lead 91 by way of a thyristor 53, 63, 73 forming part of a second group, a singe quenching circuit 30...34; 40...44 being provided for each of the two groups, each phase being connected to a positive and a negative reverse-current lead 101, 102 by way of respective reverse-current thyristors 56, 66, 76; 55, 65, 75, a diode 103, 104 being arranged between each reverse-current lead and the relevant supply lead. The invention is applicable to supply of power to an asynchronous motor 80 ... 82 and is particularly suitable for high frequency operation. The Specification explains how a thyristor of the first group 50, 60, 70 is quenched by triggering commutating thyristors 30, 33 and the reverse current thyristor associated with the cathode of the main thyristor to be quenched so as to discharge capacitor 34 reversely through the main thyristor. In order to quench the next thyristor of that group, commutating thyristors 31, 32 must be triggered. Harmonic-filtering chokes 58a, 68a, 78a; 58b, 68b, 78b may be included if the load has insufficient inductance. The cores 103a, 103b may form opposite sides of a U- or 0-shaped iron core. In Fig. 1a (not shown) a single inductor is included in series with each phase while in Fig. 1b (not shown) each phase is connected to the centre tap of a choke. Starting.-Two thyristors of each quenching bridge are fired before the main thyristors so as to charge commutating capacitors 34, 44 from the voltage at the centre-tap 112 of the D.C. supply, inductors 107, 108 allowing the voltage, to increase substantially to the supply voltage. Regenerative braking is achieved by triggering the reverse-current thyristors 55 ... 75 when it is desired to turn off the appropriate main thyristor, current is then returned to the supply 11, 12 via diodes 103, 104.

Patent GB-303023-A (GB)
IPC: B61H7/08
Filed: 1928-12-24
Abstract: 303,023. Berliner Strassenbahn- Betriebs Ges. Dec. 24, 1927, [Convention date]. Electric and magnetic; fluid - pressure. - The power applied to the brakes acting on the several axles of a railway vehicle is varied according to the direction of travel of the vehicle so as to take into account the variation of the loading of the axles due to the tipping action set up when the vehicle is retarded. In the case of a vehicle mounted upon maximum traction trucks or bogies as shown in Fig. 1, if the vehicle is retarded when travelling in the direction of the arrow, the load on the running axle III is considerably increased and that on the running axle II is reduced as compared with the loading when the vehicle is at rest or in uniform motion. If the direction of travel is reversed the load on the axles II, III is respectively increased and reduced. The driving axles I, IV may be braked in known manner by connecting the driving motors as generators and the running axles II, III by solenoid actuated brakes or magnetic disc brakes supplied by the short-circuit current generated by the motors, by the trolley current or other source. As shown in Fig. 2 the solenoids SII, SIII of the brakes of the running axles II, III are connected in parallel to the fingers B1, B2 of the two braking controllers at the respective ends of the vehicle in such a manner that when braking is effected by the controller at the left hand end of the vehicle current is supplied at full strength by the finger B1 to the solenoid SIII of the running axle III but is weakened by passage through a resistance V in the solenoid SII of the axle II which with this direction of running is the less heavily loaded under retardation. If the vehicle is running in the opposite direction current is supplied to the solenoids by the finger B2 of the right hand controller and in this case the resistance V is included in the circuit of the solenoid SIII. The usual brake resistance B2 and coupling boxes L1, L2 for connection to the, trailer are shown. Instead of the change of braking power being effected automatically as above described a hand, operated change-over device may be employed. According to the Specification as open to inspection under Sect. 91 (3) (a) when pneumatic brakes are used, pressure reducing valves may be provided in the supply pipes of the brake cylinders for the axles affected so as to obtain the desired ratio of braking effort according to the direction of travel. This subject-matter does not appear in the Specification as accepted.

Abstract: 942,986. Telegraphy. GERAETEWERK KARL - MARX - STADT VEB. Oct. 16, 1962, No. 39128/62. Heading H4P. Movement of each selector ring 2 of a pageprinting telegraph receiver is controlled by means of an armature 13. The armature is pivoted at 14 on the type-head assembly 1 which moves across the page to effect printing, and it is arranged to be passed along the gap between the arms 17 of an electromagnet. Each received code element causes the corresponding electromagnet to be energized in one sense or the other, depending on the sign of the element, and so the armature 13, which is a permanent magnet, takes up one or other of its stable positions. In doing so, the armature moves its associated selector ring 2. A stop 9 limits the amount of rotation of the ring and further limits the rotation of the armature such that there is always an air gap between the poles of the armature and the yoke of the electromagnet.
