Abstract: 1280411 HVDC transmission systems BROWN BOVERI & CO Ltd 26 Aug 1970 [28 Aug 1969] 41078/70 Heading H2F In a HVDC transmission system, the main converting elements are protected against overvoltage during disturbances by arranging for the rectifying stations to change over temporarily to inverting operation so that the current on the DC side is gradually decreased. In a system including two rectifying sections and two inverting sections, during the response time of the automatic cut-out of a faulty section, the direct current of the fault-free section is arranged to be increased by lowering the voltage at the inverter in such a manner that the fault-free section takes substantially the same reactive power as both sections together before the disturbance. Overloading of an inverter having commutation failure may be prevented by varying the reactive power output of a rotary phase shifter connected across the three-phase supply. The current regulator of the rectifier may be arranged to limit the rate of change of current.

Abstract: 1,079,039. Supervising unattended repeaters &c. ELLIOTT BROS. (LONDON) Ltd, Jan. 22, 1965 [Nov. 1, 1963], No. 43182/63. Heading H4R. In a system for identifying faulty component units in a signal transmission system, a test signal is passed through the system and the level of the test signal monitored at the output of each component unit to derive a group of signals which, when fed to a logic circuit, identifies a faulty component. The logic circuit may control the insertion of a spare component unit to replace a faulty unit. Fig. 1 shows a system in which two identical signal channels A 1 , B 1 , C 1 , and A 2 , B 2 , C 2 , are provided with switching circuits a 1 , b 1 , c 1 , a 2 , b 2 , c 2 , p 1 , p 2 , so that any unit in either channel may be disconnected and replaced by the corresponding unit in the other channel. Each channel is fed with an " out of band " test signal T and the test signal recovered at the output of each unit and fed, e.g. at R 11 , R 12 , R 13  &c., to comparator units, e.g. S 11 , S 12 , S 13  &c., where it is compared with a reference level derived from the test signal via units, FA1 or FA2, FAB1 or FAB2 &c. The difference signal is rectified in rectifiers Re and if the level of the difference signal exceeds a predetermined amount the corresponding one or ones of triggers Tr is operated to provide outputs on corresponding leads r 12 , r 22  &c. The resulting signals are fed to a logic circuit S comprising "negator" stages N, "and" gates An, and "or" gates O, the outputs of which are signal leads to control the switching stages a 1 , b 1 , c 1 , p 1 , a 2 , b 2 , c 2 , p 2 , so that on occurrence of a fault in one component unit the faulty unit is switched out and the corresponding unit of the other channel is switched in. In addition the reference level deriving units are duplicated, e.g. at FA 1 , FA 2  &c., and if one of these is detected as faulty the corresponding changeover switch, e.g. fa, is operated to substitute the alternative unit, e.g. if comparators S 21  and S 11  produce an output signal due to FA 1  being faulty outputs would appear at r21 and r11 to operate the lowest " and " gate An in the logic unit S to produce an output to operate fa to switch in the alternative unit FA 2 . A preferred form of switching unit b 1  is described with reference to Fig. 2 (not shown) in which when a unit is substituted for a faulty unit it is fed with a signal derived from an averaging circuit fed from the output of the corresponding previous stage in both channels.

Abstract: 955,538. Capsules. NATIONAL CASH REGISTER CO. Nov. 15, 1962 [Dec. 22, 1961], No. 43255/62. Heading B8C. A process for producing minute capsules and aggregates thereof, includes the steps of forming an aqueous solution of an encapsulating wall material consisting at least partially of zein at a pH value of 9 to 11, dispersing the intended core material as particulate entities therein by agitation of the system, lowering the pH to below 5.5 to cause phase separation of the wall material which deposits as a solvated solid around each core entity, and cross-linking the deposited wall material to form a rigid waterinsoluble wall, by treating the capsules with a cross-linking agent. Deanimated zein may be used with sodium carboxymethyl cellulose or polyvinylmethylethermaleic anhydride or polyvinylpyrrolidone or gum arabic or polyethylenemaleic anhydride to form the wall material; the pH value is lowered by adding aqueous acetic acid solution to the system. The crosslinking material is glutaraldehyde sol, alphahydroxyadip-aldehyde. In all examples the phase separation is caused by lowering the pH value. All examples are produced at room temperature. The core material may be liquid (oil), crystalline or amorphous and of any shape. The capsules are recovered by filtering, decantation, or centrifuging and then dried.
