Abstract: 1369059 Automatic exchange system NIPPON TELEGRAPH & TELEPHONE PUBLIC CORP NIPPON ELECTRIC CO Ltd HITACHI Ltd OKI ELECTRIC INDUSTRY CO Ltd and FUJITSU Ltd 3 Nov 1971 [6 Nov 1970] 51103/71 Heading H4K [Also in Division G4]  A data processing system includes several main memory devices, at least one standby memory device, the memories being controlled by duplicated control devices, a number of relatively slow back-up peripheral. memory devices, means for periodically copying data from the main memory devices into the back-up stores, and means operative on the failure of one of the main memory devices to transfer the data stored by that main memory device from the back-up stores to the standby memory device.  The system is said to be particularly suited for use in a program controlled electronic telephone switching system. As described two identical central control units 10 and 11 operate in parallel, a check circuit 12 being provided to check the operation of the two units. Three main memory devices 20, 21 and 22 having internal error checking arrangements, such as parity circuits, are provided together with a standby memory 29 which is used to replace a faulty main memory device. Additional back-up stores, e.g. drums 30 and 31, magnetic discs or tapes, are also provided. In an electronic switching system the stored data may be divided into two classes, viz., permanently stored data such as the program, and variable operating data. The permanent data may be stored in a read only memory or an erasible memory in which the write facility is inhibited.  Initially the permanent data is copied into an area of the back-up storage. During operation the variable stored data is periodically copied into alternate ones of two areas in the back-up stores as shown in Fig. 2. In practice the standby memory 29 is initially loaded with the contents of one of the other main memories, usually the permanent data referred to above. Thus if that other main memory fails it is disconnected and immediately replaced by the stand-by memory. Should one of the main memories whose contents are not duplicated in the stand-by memory fail then the faulty memory is disconnected and the relevant data copied from back-up storage into the stand-by memory which is then connected to the system to replace the faulty memory. The Specification contains some discussion of the efficiency of the system which is somewhat less than that of a fully duplicated system due to the fact that variable operating data in the back-up store is out of date in some degree. Details of the costs of the present system compared to a fully duplicated system are also given.

Abstract: 1534287 Welding by pressure GENERAL ELECTRIC CO 15 Dec 1975 [2 Jan 1975] 51258/75 Heading B3R In a method for pressure welding components 10, 16, the surfaces 12, 18 to be joined are uniformly pre-heated by a high frequency induction heater, e.g. an element 20, located in a gap 14 between the surfaces 12, 18 and then impacted together to produce a forged joint. The method is of particular use for joining components of different and varying crosssections (e.g. an air-foil as shown, Fig. 4) in which case to ensure uniform heating the heating element 20 approaches the surface 12 at the point 20a of maximum width. The shape of the heating element varies with the shape of the workpieces to provide uniform heating across the surfaces to be joined. In apparatus (Fig. 8) disclosed components 16, 16a are held by holding fixtures 30, 30a in spaced apart relationship. On the surfaces reaching the required temperature a radiation sensor 38 (e.g. an optical pyrometer) triggers a solenoid 36 to retract the heating element 20, and by way of a control 46, triggers an hydraulic ram 44 to bring the components together. A stop 48, either physical or electronic, regulates the amount of upset. Components of Ti, Fe, Co, Ni and their alloys are specified using temperatures of between 1600-2300‹ F. and pressures of 30,000- 60,000 p.s.i. The welding may be effected in an air, vacuum or non-oxidizing environment. Explosive forging may be employed in place of the hydraulic ram.

The other side of the device is connected to a capacitive voltage divider, and the arrangement is such that the starting operation is not repeated after the lamp has lit. In the circuit of Fig. 2, the lines A, B are connected through the lamp terminals to an A.C. source. The semiconductor switch is constituted by a triac 10 which is gated through a diac 11 by a voltage divider formed by a resistor 13 and capacitors 12, 14. A suppressor capacitor 8 and limiting choke 9 are also included. In other embodiments, Figs. 3 and 4 (not shown), further components are added to the voltage divider in order to cause the lamp to ignite gradually, and to cause a choke in series with the lamp to saturate on alternate halfcycles so that the filament current can be easily controlled. A parallel RC circuit in the voltage divider can be used to decrease the lamp intensity periodically. In another embodiment, Fig. 7 (not shown), the triac 10 is replaced by a thyristor in anti-parallel with a diode.

Abstract: 1425358 Zinc-bromine battery LITO CO Inc 7 Nov 1973 [14 Nov 1972] 51706/73 Heading H1B In a zinc-bromine battery in which the electrolyte comprises an aqueous solution of zinc bromide, the molarity of the ZnBr 2  is limited to ensure that the amount of bromide ion is not quite sufficient to support complete charge of the battery by bromide oxidation at the cathode whereby at the completion of the charge the battery voltage increases slightly and this increase may be used as a signal to terminate the charge. Moreover, the charge current tapers throughout the charge and ends at a small value. The electrolyte also comprises an additional soluble zinc salt which is non- reactive with bromine and is either non- oxidizable or more difficult to oxidize than the bromide ion. The molarity of the solution of this salt is such that the amount of bromide ion in the electrolyte is substantially less than twice the amount of zinc ion. This ensures that zinc ion continues to be available throughout the charge and the zinc plates on to the anode with a thicker and more uniform coating. The preferred additional salt is zinc sulphate. Other zinc salts which may be used are the: acetate, trifluoro acetate, nitrate, citrate, tetrafluoroborate and chloride. In a preferred example the electrolyte comprises 1À98M ZnBr 2  and 0À60M ZnSO 4 . A battery, Fig. 1, comprises a terminal cathode electrode 14, a terminal anode electrode 18 and intermediate electrodes 22 arranged in an aqueous electrolyte 23 as described above.
