Title: Machine for the dividing off and tipping of sections of roughcast materials manufactured by a continuous casting process
Inventor: PEYTAVIN PIERRE
IPC: B22D11/126
Filed: 1966-02-14
Abstract: 1,132,481. Continuous-casting apparatus; severing by grinding or by fusion. SOC. CIVILE D'ETUDES DE CENTRIFUGATION. 14 Feb., 1966 [12 Feb., 1965], No. 6428/66. Headings B3D, B3F and B3V. A length is cut off a continuously-cast, hollow or solid strand by a cutter 26 which moves down with the strand as it cuts (by O 2  jet, blowpipe or grinding wheel) and the length is lowered further into a vertical tipping-cradle 1 (by means of a supporting thrust-block 10 moved by, and able to move, an endless chain 12 extending the length of the cradle) until the cradle is tipped about a mid-point 3 to a horizontal position, whereupon the thrust-block 10 is driven to pass the cut length on to a conveyer (34), Fig. 2 (not shown). The cutter 26 is mounted on a carriage 19 biased to an upper position by a pulley and counterweight 25 but lowered when the weight is lifted, Fig. 5, by a rising stop 28 on the thrustblock chain 12 as the strand moves down into the cradle 1. The position of stop 28 is adjusted to determine the length cut off. The strand is received in the cradle in a long cylinder 8, Fig. 1, having a longitudinal slot 9 to accommodate a support of the thrust-block 10, which reciprocates in the cylinder. A head 11 on the thrustblock is shaped to centre the end of the strand and is rotatable to accommodate a rotated strand. A motor 17 on the carriage 1 drives the thrust-block chain 12 by way of a shaft 16 and pinion 14 to unload the cut length, but, when the thrust-block 10 is descending and supporting the strand or out length, the chain drives the shaft together with a pump 18 to absorb some of the torque produced and limit the shaft speed and the rate of descent of the block and its load. An electrobrake reduces the speed of descent at the end of the stroke. During the tipping of the cradle (by a rack 5 and cogged segment 4 operated by an hydraulic jack 6) a supporting block 27 is placed automatically under the strand end from which the cut has been made.

Inventor: ASBURY ALLAN
IPC: H02P25/02
Filed: 1958-02-27
Abstract: 889,972. Supply systems depending on the use of two or more machines. ENGLISH ELECTRIC CO. Ltd. Feb. 26, 1959 [Feb. 27, 1958], No. 6449/58. Class 38 (4). [Also in Group XXXVII] A supply system for a polyphase synchronous motor 33 comprises a sine wave generator 10 in the form of a resistor 11 mounted on a rotatable shaft and having tappings connected to a commutator. Opposite points on the resistance element are connected to a neutral slip-ring 12 and two points in quadrature are joined to slip-rings 13, 14, which are in turn connected to a D.C. source 15. When the generator is driven by a D.C. motor 19, a three-phase sinusoidal output is obtained between brushes 16 . . . 18, which bear on the commutator and the neutral slip-ring 12. The output of the generator is applied to control windings of three pairs of push-pull connected magnetic amplifiers which also have biasing windings, and which supply bridge circuits including two-section field windings of D.C. generators G1, G2, G3. Each generator supplies one phase of the motor 33, the speed of which is varied in accordance with that of the motor 19. A voltage feed-back circuit for each generator includes ganged variable resistors 39 . . . 41 and the control windings of the associated amplifier. Further resistors 42. . . 44 are interlocked with the speed-controlling resistor 24 for the motor 19, whereby the generator output voltage increases with increase of frequency of the sine wave generator. Braking resistors may be connected permanently or temporarily across the phase windings of the synchronous motor. The motor 33 may be coupled to a cable drum for raising and lowering a control rod for a nuclear reactor.

Title: Malting apparatus
IPC: C12C1/027
Filed: 1977-02-18
Abstract: 1509484 Malting VICKERS Ltd 18 Feb 1977 [19 Feb 1976] 6672/76 Heading C6E The germination and subsequent kilning of steeped barley 13, Fig. 1, is carried out in two or more vessels 1, 2 of which the intake passage 18 of the one vessel 2 is selectively connectible through valving (as shown) to fresh air from the atmosphere through valve 15, exhaust air diverted from the exhaust duct of the same vessel through valve 17 and exhaust air diverted through valve 8A from the exhaust duct of the other of the two adjacent vessels, whereby economies in the use of heated air are realised. The passage 18 contains a fan 9, heater 11 and water-spray humidifier 10. During a malting process, in each vessel steeped grain is germinated for a period of five days, for example, and kilned during one and a half or two days, and by arranging the operating cycle for vessel 2 to be one day behind that of vessel 1, and so on, the surplus heat in the air exhausted from vessel 1 in the later stages of the germinating or kilning can be usefully applied at the correspondingly earlier stage in vessel 2. An open-ended chain or, alternatively, a closed loop may be formed by connecting together say, five or seven of the vessels. The plant may be constructed from metal, or from brick or concrete.

Title: Improvements in or relating to nuclear reactors
Inventor: PRATT HENRY REGINALD CLIVE
IPC: G21C1/08
Filed: 1956-03-05
Abstract: 795,406. Nuclear reactors. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. March 4, 1957 [March 5, 1956], No. 6836/56. Class 39(4). A nuclear reactor comprises fuel elements of such shape and dimensions as to provide a smooth continuous surface, a further continuous surface closely adjacent to said surface to define a passage capable of supporting a climbing film system when the reactor is in operation, and means for feeding coolant liquid to the lower end of the passage at such a pressure head and feed rate that a climbing film system is set up. Fig. 2 illustrates the behaviour of a coolant liquid as it passes upwardly through the annular space between a fuel element 12 and a coolant tube 1. In region A there is normal ebullition, and in region B discrete annular slugs of liquid 15 surround annular vapour slugs 16. In region C a climbing film system is set up with liquid films attached to the coolant tube 1 and to the fuel element 12 and vapour in the annular space between ; finally in region D there is a spray region where the films are disrupted. The onset of this spray condition should be avoided except where a ceramic type of fuel element is used over this region. Fig. 1 shows a reactor in which the climbing film region can occupy 60-80 per cent of the total height of the coolant tube and the spray region eliminated by choosing appropriate dimensions and by adjustment of the coolant pressure head and feed rate. The steam produced and the residual coolant liquid leave the coolant tubes at the top and the two phases are separated by individual separators 19. The bulk moderator fluid 8 and the coolant liquid are the same, e.g., water or heavy water, so that the separated liquid may be passed directly into the bulk of the moderator. The steam passes out of the pressure vessel to turbines 21 after which it is condensed and returned to the coolant header tank 10. In an alternative arrangement the coolant tubes 1 pass into a common header and thence to a single external cyclone separator ; this may be better if the coolant liquid is not the same as the moderator liquid.

Title: Improvements in or relating to torque indicating or measuring devices
IPC: G01L3/10
Filed: 1944-04-13
Abstract: 578,860. Electric indicating systems. SHEPHERD, G. R. (Westinghouse Electric Jnternational Co.). April 13, 1944, No. 6853. [Class 40 (i)] [Also in Groups XIX and XXXVI] A device for indicating or measuring the torque of a shaft comprises a rotor assembly secured to rotate with the shaft of a stationary electromagnetic element, and at least one magnetic flux path linking said rotor assembly and said stationary element, characterised by means for producing an alternating magnetic flux in the magnetic flux path and means forming part of the rotor assembly responsive to the torque characteristics of the shaft for changing the value. of said alternating flux thereby inducing voltages in the stationary element indicative of the torque of said shaft. The rotor assembly 3, Fig. 1, comprises a pair of axially displaced torque rings 7 and 9 of magnetic material having axially extending fingers 7a and 9a. The rings 7 and 9 are mounted on non- magnetic bushings 11, 13 which are secured to rotate with the shaft 1. Between adjacent fingers 7a and 9a are airgaps 14. The stationary member 5 is annular in shape and forms two circular air gaps 21 and 23 with the torque rings 7 and 9 respectively. A coil 25 is secured within the annular recess of member 5 and is connected as one leg in a conventional bridge circuit 27 which is supplied with alternating current and adjusted to a balanced condition when the shaft is not loaded so that a voltage will not appear across the terminals of an indicating meter 29. When the coil 25 is energised a flux flowing in the clockwise direction as shown Fig. 1 is induced in the stationary member 5 and the rotor assembly 3. The flux path includes stationary member 5. air gaps 21, torque ring 7, finger 7a, an air gap 14, finger 9a, torque ring 9, air gap 23 and back to the stationary member 5. The size of the air gaps 14, 21, 23 and the shapes and sizes of the confronting faces across said air gaps are such as to compensate for end thrust in the shaft bending of the shaft and temperature variations in the shaft. If the shaft 1 is not transmitting a torque whether it is stationary or rotating the voltage in the coil 25 will remain constant. If, however, there is circumferential deflection of the shaft due to torque the air gaps 14 will increase or decrease depending on the direction of the distortion, the value of the circulating flux will be altered so that the voltage in the coil 25 will change thereby unbalancing the bridge current causing a voltage indicative of the torque to appear across the terminals of the indicating meter 29. Fig. 3 shows a further embodiment in which four coils 25a, 25b, 25e, 25d are used and a third ring 31 also secured to rotate with the shaft 1 and having axially extending fingers is provided. Further modifications are shown in the drawings. Specification 578,859, [Group XIX], is referred to.

Title: Arrangement for steering axles of rail vehicles
IPC: B61F5/38
Filed: 1950-03-23
Abstract: 689,048. Fluid-pressure servomotor-control systems. KRUPP LOKOMOTIVFABRIK, F. March 23, 1950 [March 24, 1949 ; May 11, 1949; July 30, 1949 ; Sept. 5, 1949], No. 7297/50. Class 135 [Also in Group XXXI] Relates to a vehicle steering arrangement (see Group XXXI) in which the axles of a rail vehicle bogie are carried at each end by an eccentric ring element 9. The movement of the elements 9 are correlated so that the axles are arranged radial to a curve in the rails by each element carrying a sprocket, the sprockets on each side of the bogie being interconnected by a chain 34 so that movements of the chains in each bogie in opposite directions will cause them to move from their parallel positions into converging positions. This movement is caused by oil pressure on either side of pistons 40 connected by piston rods 39 to the chains 34. Oil pressure is generated in an accumulator (not shown) by a pump (not shown) driven by the bogie wheels, pressure to the piston 40 through a pressure conduit 48 and exhaust conduit 45 being controlled by a valve 44 which is connected to a rod 49, the end 50 of which is connected to a lever 51 connected at one end 52 to the eccentric ring 9 and the other end 53 by a rod 54 to the end 55 of an arm 56 depending from the vehicle frame. On movement of the bogie relative to the vehicle frame on the vehicle passing round a curve in the rails, the end 55 is displaced to 58, the end 53 to 59, and the end 50 to 60, thus opening the valve 44 and causing pressure to be admitted to the left-hand side of the piston 40. This pressure causes the eccentric ring 9 to move anticlockwise in Fig. 6, the end of the axle 7 to be displaced so as to lie radial to the rail curve, and the end 52 of the lever 51 to move to 62, thus returning the valve 44 to its original position.
