Patent GB-1264538-A (GB)
IPC: H02M1/06
Filed: 1969-03-24
Abstract: 1,264,538. Commutation in static inverters. TOKYO SHIBAURA ELECTRICCO. Ltd. 24 March, 1969 [25 March, 1968; 28 March, 1968; 11 March, 1969], No. 15272/69. Heading H2F. In an inverter all conducting thyristors supplying. a load are turned. OFF simultaneously by a common commutating circuit which may additionally have a supplementary D.C. energizing source. Operation.-The inverter, Fig. 1, comprises inverting circuit thyristors 15 to 18 with antiparallel feedback diodes 19 to 22. Commencing with a. commutation capacitor C6 uncharged, Th 3 and Th 8 are fired to charge C6 to polarity indicated. Th 15 and Th 18 are fired to pass current through the load. When C6 is fully charged Th 8 will turn OFF. Th 11 is then turned ON at a predetermined instant and C6 will tend to discharge through Th 3, diode 13, Th 11 and inductor L12 opposing current through Th 3 in the forward direction and eventually turning it OFF.. Discharge of C6 continues through a diode 4 and L12 functions to charge C6 in the opposite direction to that indicated in Fig. 1. If the voltage of a supplementary D.C. source 9 is larger than that of the inverter supply source 1 then C6 will be additionally charged from source 9 through a diode 10, Th 11, L12, C6, diode 4 and source 1. When C6 is fully charged oppositely Th 11 will turn OFF. With a resistive load, when thyristors 3, 8 and 11 are OFF the main. thyristors 15, 18 will also turn OFF. With an inductive load current will continue to flow maintaining conduction of Th 15 and. Th 18.. Therefore when C6 is fully charged oppositely as above, Th 8 is turned ON again so that C6 discharges through L7 and Th 8 to block current through Th 18 and Th 15 turning them OFF. C6 will then become charged to. the polarity indicated by energy stored in L7, causing Th 8 to turn OFF. Th 3, Th 16 and Th 17 are then fired to pass current through the load and the cycle continues. In an alternative embodiment (Fig. 6, not shown) the supplementary source 9 is omitted and the D.C. source 1 is at constant voltage, while in Fig. 9 (not shown) the inductor 12 is omitted and the inductor 7 serves a dual purpose. In a further embodiment (Fig. 10, not shown) the inductors 7 and 12 are close coupled on a common core, which is said to reduce commutation time. The inverter may be polyphase.

Abstract: 1297847 Welding by pressure A I WELDERS 13 July 1971 [13 April 1970] 17511/70 Heading B3R In a friction welding process in which the initial length of the components to be joined may vary but in which a predetermined final length is to be achieved, the frictional heating phase is continued until a predetermined length of the components is reached due to burn off and forging pressure is then applied the value of the forging pressure being controlled (reduced) in dependence upon the amount by which the heating phase exceeds a pre-set period. In a friction welding machine for carrying out the process a limit switch starts a timer at or just before the instant of contact of the workpieces. Alternatively a pressure switch, sensitive to the rise in pressure upon contact of the pieces, may be used to operate the timer. After a given period has elapsed the timer operates electrohydraulic or mechanical/hydraulic means to progressively reduce the value of the forging force to be applied. A further limit switch is operated when the components to be joined have reached a preset length and forging pressure is then applied at the value to which it, by then, has been reduced. The forging pressure remains constant as this reduced value during the forging phase.
