Title: Improvements relating to remote control systems
IPC: B61L7/08
Filed: 1945-10-02
Abstract: 601,409. Electric control systems. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd. Oct. 2, 1945, No. 25563. Convention date, Nov. 15, 1944. [Class 40 (i)] Relates to a remote control system of a central office and a plurality of remote stations in which any remote station can communicate with the central office by transmitting an impulse to actuate a relay at the central office to reverse line current which is then interrupted in accordance with code by a relay at the remote station, and consists in providing a rectifier in series with the line relay at each remote station to eliminate weakening of line current by the parallel circuits of other remote stations. Transmission from central office and reception at station.-Relay OM is energized to complete circuit of relay OT for operation by coding unit CU. Relay OT operates to reverse contacts b, d and interrupt the line current in accordance with the code signal. At remote stations relays R are operated by the coding signal to select that station appropriate to the signal. Transmission from a remote station to central office.-Relay M at the remote station is energized to reverse the connections of relay R and short circuit the line YZ over contacts of relays E and LBP, so that relay R releases and the line current is increased to reverse relav OR at the central office. Relay PC picks-up to reverse the polarity of the line current and release relays R at all stations, and the office coding unit CU is simultaneously connected to energize relay OLBP to complete a holding circuit for relay PC until the code from the remote station is fully received when relay 016 operates to de-energize relay PC. Relay M at the transmitting station also completes a circuit for the operation of relay T by the station coding unit CU so that the reversed line is interrupted under the control of the station coding unit, which also operates relay LBP so that relay R operates in unison with the releases of relay T. Relay OR thus responds to interruptions of the reversed line current to control the coding unit CU at the office. At the end of the signal, relay PC releases to restore the polarity of the line current. The rectifier 6 at each remote station prevents those stations in which relay M has not operated from weakening the interruptions in the reversed line current. Where a near station overloads the filter coils 12, a relay ORA, Fig. 2 (not shown) may be operated to reduce line current by switching out part of the battery 80. Simultaneous initiation of transmission from several remote stations.-The codes are assigned so that the station nearer the central office will prevail. Specification 589,332 is referred to.

IPC: H05B6/02
Filed: 1952-10-14
Abstract: 745,285. Hardening metals. ELECTRIC FURNACE CO., Ltd. Oct. 7, 1953 [Oct. 14, 1952], No. 25677/52. Class 72. A method of hardening a rigid elongated metal shaft or bar comprises supporting the workpiece at spaced points along its length on either side of an electromagnetic inductor through the heating zone of which the workpiece extends, and producing relative movement parallel to the axis of the workpiece between the workpiece and the inductor to cause the latter to heat the workpiece progressively along its length, and is characterised in that, during the heat-treatment, the workpiece passes through an intermediate supporting guide, fixed adjacent to the inductor, which prevents lateral distortion of the workpiece caused by the bending of its heated portion in the region of the inductor. The supporting guide, which may be a close-fitting liquidcooled bush, may be located in between the inductor and quenching device, within the inductor itself, or may be mounted on the side of the inductor remote from the quenching device. Fig. 2 shows an inductor-quench assembly for the simultaneous treatment of two verticallymounted workpieces and comprises an inductor 24, quenching rings 26 and two pairs of bushes 33, 35. The upper bushes 33, which are mounted in a water-cooled support 34, are located close to the top of the inductor and thus restrain any lateral distortion of the workpieces adjacent to the inductor where the heating is greatest, and the lower bushes 35 provide lateral support below the heating zone. In the embodiment shown in Fig. 5, a workpiece 40 is passed longitudinally through an inductor 44, within which is incorporated a guide sleeve 46 for supporting the workpiece against distortion, and a quenching ring 45. Immediately beyond the quenching ring 45 is provided a second supporting guide in the form of a saddle block 47, on which the lower surface of the workpiece can rest to prevent any sagging, and beyond the said saddle block an auxiliary quenching ring 48 is mounted to cool the workpiece further. Specification 585,416, [Group XXX], is referred to.

Sept. 25, 1933, No. 26392. Void [Abridged as open to inspection under Sect. 91 of the Acts, March 24, 1934]. [Class 38 (ii)] Relates to a method of controlling the interchange of power between circuits 10, 11 which are interconnected through a pair of serially connected groups of valves 16, 17 and 18, 19 and consists in operating one group of valves to supply a substantially constant voltage to the load circuit and controlling the other group of valves to either boost or buck this voltage. In transmitting energy from an A.C. circuit to a D.C. circuit, for example, one group of valves operates continuously as a rectifier while the other group is controlled to operate either as a rectifier for maximum voltage or as an inverter for minimum voltage. The control is effected by altering the phase of the grid voltages. Similarly for transmitting energy from a D.C. circuit to an A.C. circuit one group operates continuously as an inverter while the other group is controlled to operate either as an inverter or as a rectifier. In a modification of Fig. 1, the transformer 12 is omitted and the A.C. circuit connected directly to the valves 16, 17 and 18, 19. An arrangement for interconnecting a polyphase A.C. circuit and a D.C. circuit is described in which the circuits are interconnected by means of two pairs of groups of valves, all the groups being connected serially across the D.C. circuit. Fig. 5 shows an arrangement for interconnecting two single phase A.C. circuits 59, 60 in which two bridge arrangement of rectifiers 61, 62, 63, 64 and 65, 66, 67, 68 are connected serially with respect to one network and in parallel with respect to the other.
