Title: Improvements in and relating to electro-hydraulic devices
Inventor: CORBETT JAMES PATRICK
Filed: 1954-12-21
Abstract: 768,861. Electromagnetic couplings. ENGLISH ELECTRIC CO., Ltd. Dec. 21, 1955 [Dec. 21, 1954], No. 36913/54. Class 35. A magnetic fluid coupling comprises a non- magnetic input disc or drum to which the fluid is caused to adhere by means of a stationary magnetic field, this giving part of the liquid a kinetic energy producing a jet or stream which drives an output member. In the form shown in Fig. 2 the casing 12 forms the input member driven by shaft 12b, and has a magnetic annular member 15 spaced from its end-wall 12a by pillars 16. Flux from magnets 17 causes fluid to adhere to the surfaces of the annulus 15 and the end-wall 12a so that it has a tangential velocity which causes it to leave the area of the magnets and pass in jets into ducts 11c in a stationary reaction member 11. These ducts direct the jets on to the turbine blades 10c of the torque output member 10. The fluid is returned through fixed ducts 11h. The speed may be adjusted by varying the radial positions of the magnets 17, or by moving them away from the end-wall 12a to reduce the flux, or if desired, adjustably excited electromagnets may be used, or the reaction member may be allowed to move under brake control. In a modification, Fig. 3, the input and output members comprise non-magnetic drums 24, 25 coupled to shafts 24a, 25a respectively. Fixed magnets 28, 29 cause a jet of fluid to be thrown up from the lower member to drive the upper member. If desired, the output member may be a turbine. A modification is described in which the magnets act radially of the drums, in which case the ratio of transmission may be varied by making the drums oppositely tapered and moving the magnets axially. In the form shown in Fig. 6, the driving and driven members comprise concentric drums 50, 52, having magnets 53, 54 respectively, the fluid jet being guided by a guide member 51.

Title: Improvements in or relating to the injection of fuel into a blast-furnace
IPC: C21B5/00
Filed: 1962-10-01
Abstract: <PICT:0960748/C6-C7/1> The aggregate flow of fuel injected at the tuyeres of a blast furnace is controlled as a direct function of the blast pressure within certain defined limits of the latter, outside of which the fuel addition is completely cut-off. Furthermore the flow of fuel to an individual tuyere may be interrupted when the blast flow therethrough falls below a preset limit.  In the apparatus illustrated the blast arriving via pipe 6 is monitored by pressure meter 15, and the flow of fuel in pipe 9 is monitored by flow meter 13, the readings of these instruments being transmitted to pneumatic regulator 14 which operates valve 16 in such a way that the flow of fuel is maintained in direct linear relationship with blast pressure. A pressiostat 17 having maximum and minimum contacts controls fuel stop valve and cuts off the flow when the blast pressure varies beyond the limits set.  In each blast-inlet 3, there is a Venturi 20, with which is associated differential pressure gauge 21.  The latter effects closing of stop valve 22 when the blast flow to the tuyere in question falls below a predetermined minimum.

Abstract: 1334500 Mounting of a firing weapon WERKZEUGMASCHINENFABRIK OERLIKONBUHRLE AG 10 Aug 1972 [20 Aug 1971] 37327/72 Heading F3C A firing weapon 11 is mounted in a cradle 12 which is pivoted at 13 on an elevating mechanism 6 carried by a vehicle chassis 1 and the cradle is moved in a direction opposite to the direction of the tilting movement of the vehicle when the weapon is fired. The pivot point 13 is upwardly offset by an amount a with respect to a recoil force P which passes through the centre of gravity T and the mechanism 6 is elevated by a piston 7 and cylinder 8 assembly which is pivotally mounted at 9. The relative movement of the cradle 12 with respect to the elevating mechanism 6 is limited by stops 14, 15, a spring 16 and a damping member 17 being positioned between the stop 15 and the elevating mechanism 6. The spring 16 is pre-stressed to force the cradle against the stop 14. The firing of the weapon produces a recoil force P and a moment M2 tilts the vehicle chassis about a point K. The magnitude of the movement M2 depends upon the size of the elevation angle α, the increasing of the latter reducing the effect of the force P. The latter also causes a moment Ml which is opposite to the movement M2 and causes the weapon 11 to tilt downwardly through an angle # in opposition to the spring 16 and to the damping element 17.

Title: Data transmission systems
IPC: H04B7/02
Filed: 1974-08-30
Abstract: 1479028 Diversity systems SIEMENS AG 30 Aug 1974 [6 Dec 1973] 37956/74 Heading H4L In a diversity system, a data signal whose binary value changes within a given test period is transmitted. At the receiving end of the system a test device produces test signals in dependence on the received signals, and in dependence upon the test signals a quality evaluation stage produces control signals to operate a channel switch, such that one of the diversity channels is connected via a receiving channel to a data sink. For each diversity channel the test device produces a first type test signal dependent upon the presence within the test period of at least one change in the binary value of the signal transmitted and a test signal of a second type dependent upon errors in the times of occurrence of pulse flanks of the signal transmitted-failure to reproduce binary changes at the receiver, or producing them at the wrong time indicates a defective channel. An evaluation of binary value changes enables the best channel to be selected independently of the level of the transmitted signals even when very high levels appear on one channel as a result of interference. The received bit rate of the received data signal may also be monitored and used in the quality evaluation. The system described uses frequency diversity; signals from a data source such as a teleprinter DQ are coded (CD) modulated on different carriers (at MD1-MD3) and transmitted by transmitter FS. Following reception at FE, the signals are demodulated from the various carriers at DM1-DM3 and the demodulated signals are applied to a test device PR and sync device SYN which provides appropriate timing signals T1-T6. In the test device (PR Fig. 2 not shown) three signals are produced for each of the detected signals D1-D3: (a) Received pulses are differentiated and the differentiated pulses are compared with the timing signals which are established in appropriate patterns throughout a test period. The existence of a binary transition within the test period is detected to cause an output pulse P11 to assume a zero value; (b) Errors in the positions of pulse flanks are detected by comparison with appropriate timing pulses and output pulses P12 generated in dependence on the timing error; (c) Wrong frequency pulses are detected and output pulses P13 generated. These pulses are applied to counters in a quality evaluation circuit QB one for each diversity channel and counted over the test period (Fig. 5 not shown). The first pulses representing non-appearance of transitions are given most weight by the counters. The count outputs are compared by suitable logic (Fig. 6 not shown) to determine which channel has given rise to the least count and is thus the best quality. Signals representing this are applied to further logic (Fig. 7 not shown) which controls a channel switch RS in accordance with whichever is the best quality channel. Should two channels be of equal quality, the switch is not changed from its setting in the previous test period if it was set to one of these channels.

Abstract: 901,359. Mine cage-control apparatus. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Nov. 28, 1958 [Nov. 28, 1957], No. 38509/58. Class 78 (3). Relays P1, P2 (Fig. 1), controlling electric plant, are separately excited from an alternating current energized line L1, over a single conductor X1 and blocking rectifiers 1-4, by buttons A and C respectively. Discharge rectifiers 15, 16, or condensers (not shown), are provided to prevent spurious actuation of the other relay during the half-cycle periods when each relay is not being excited. The apparatus may be incorporated in a mine cage control system (Figs. 3a and 3b), in which contacts 1-13 are manually operated from the cage or mine levels, and are connected through blocking rectifiers and conductors X, Y, Z to remotely situated relays R 1-5 which respectively operate contacts S1-5 controlling the selective actuation of relays P1-13 which operate the cage driving motor and/or signalling lamps. In operation, movement of a control, associated for example with level 8, closes both contacts 8 thereby energizing relays R2 and R4. These, in turn, operate all the contacts S2 and S4 from the rest positions shown, thereby energizing relay P8 which locks over contacts Sp8 and a limit switch L8. The rest positions of contacts S1-5 and the grouping of contacts 1-13 are chosen to ensure that one relay P only is actuated for each actuation of a level control. The system has a further relay SC1 which must be operated over door closed contacts D1 and emergency stop button ES before the system can operate. In the case where the level controls are in the cage the conductors X, Y, Z may be either rigidly attached to the mine shaft, for co-operation with collectors on the cage, as incorporated in the winding cable, or another cable following movement of the cage.
