Title: Improvements in protective relay systems for electrical networks
IPC: H02H7/26
Filed: 1930-04-03
Abstract: 355,834. Protective cut-out arrangements. ALLM€NNA SVENSKA ELEKTRISKA AKTIEBOLAGET, Võsteras, Sweden. April 3, 1930, No. 10580. Convention date, Aug. 7, 1929. [Class 38 (v).] Cut-out systems employing retarded relays for the protection of a line directly connecting two feeding points of a distribution system, which points are also connected by at least one more direct line and, if desired, by not more than one indirect line are arranged so that the interruption of any of the direct lines is effected with a different retardation for different lower directional conditions in other feeders or feeder. In the system shown in Fig. 2 in which two generating stations A, B are linked by parallel feeders I, II and supply a ring-main distribution system III graded time limit relays are placed around the ring-main system with release times as indicated. The busbar and feeder protective currents of station A are shown in Fig. 1 each line having an overload relay e and directional relay d, the latter having upper contacts d<1> completed when power in the corresponding line is flowing outwardly and lower contacts d<11> for inward power flow. Normally on overload relays e, d complete the circuit of a relay c which has quick-closing upper contacts c<1> and retarded (e.g. 1 second) lower contacts c<11>. If a short circuit exists in any line, e.g. I, the power flow in at least one other line, e.g. the parallel feed 2, will be towards the bus-bars to which both feeders are connected. Thus the lower contacts d<11> of the corresponding directional relay. d will be closed and a circuit for a quick-acting relay g completed. This prepares a circuit for the tripping coil b of the circuit-breaker a in feeder I, the closure of the tripping circuit being completed by the retarded contacts c<1> of the relay c corresponding to feeder I after one second's retardation. If however the fault is not actually in line I the circuit of relay g would not be energized and tripping would not occur until a relay f with a relatively large retardation (e.g. 5 seconds) had completed its contact-closing operation. In the case of a short-circuit in line III with reverse power flow in lines I, II neither of the latter feeders are interrupted as the reverse flow of current prevents completion of the circuits of the relays c at contacts d<1>, and the relay c corresponding to feeder III completes the circuit for the corresponding tripping coil b after the completion of the time setting of its contact c<11> (i.e. 4 seconds).

Title: Improved process for cutting continuous filaments into short lengths
IPC: D01G1/04
Filed: 1950-05-05
Abstract: 688,845. Stapling fibres. PHIPPS. J. W., WILSON, A. and IMPERIAL CHEMICAL INDUSTRIES,Ltd. May 4, 1951. [May 5, 1950] No. 11153/50. Class 31 (i). [Also in Group IX] One or more continuous filaments are cut into short lengths 16, Fig. 1, by feeding them to one or more stations supplying a number of clippers d ... l mounted symmetrically around the periphery of a rotary device 1, the clippers opening in turn at the feed station, or stations, and cutting the filaments as the device rotates and then opening again to receive the filament at the same feed station or at the next station, and the filaments being gripped by the cutting surfaces of the clippers prior to being cut. A tow of filaments 15 from a reel may be thrown onto the device 1, which is mounted on a shaft 2 driven by an electric motor, and thereafter fed by rotation of the device. The position of the moving teeth 12, Fig. 2, of each clipper in relation to the fixed teeth 14 is illustrated in Fig. 1 by the distance apart of the two lines representing the clipper, the latter being open in the top position to receive the filaments and closed gradually to grip them before the cutting stroke which takes place approximately between the positions occupied by the clippers d and e in Fig. 1. The moving blades of the clippers are operated by a cam or by a disc 6 connected thereto by rods 11 having collars 10. A pin 7 projecting from the device 1 is connected to the disc 6 by a flexible coupling 8 and rotates the disc on a bearing 5 about an axis inclined to that of the shaft 2. The clippers may be modified to comprise two teeth only, or for a plurality of feeding stations, to cut in both directions of movement, or to operate on the scissor principle with pivoted blades, the cutting edge of at least one of the blades being curved to grip the filaments before cutting them. In order to reduce wear on the teeth, material to be cut may be fed to each part of the blades in turn. The length of the pieces 16 may be varied by increasing the radius of the clippers, removing some of them, or by feeding the filament to the device 1 at a faster speed than that at which the device is rotating. The clippers may be mounted on the inside of the device which may comprise an endless belt. The gripping action of the clippers may be assisted by a blast, or a suction stream, of air forcing the filaments against the device. The short lengths 16 may be sucked into the hub of the device 1 and discharged into a bin.
