Title: Improvements in and relating to hydraulic impulse turbines
Inventor: SEEWER PAUL WERNER
IPC: F03B15/20
Filed: 1957-09-16
Abstract: 875,519. Fluid-pressure servomotor-control systems. ENGLISH ELECTRIC CO. Ltd. Sept. 16, 1958 [Sept. 16, 1957], No. 29072/57. Class 135. [Also in Group XXVI] An hydraulic impulse turbine having at least two turbine nozzles has a by-pass inside the turbine casing branched off between the inlet piping and one of the turbine nozzles and is controlled by a regulator valve member arranged coaxially with the nozzle and serving as a bypass valve for all the nozzles. A turbine rotor 1 mounted on a vertical shaft in a casing 21 is supplied with water by nozzles 2, 2<SP>1</SP>, connected to a distributing pipe 102. Each nozzle is controlled by a needle valve 104 operated-by the piston 115 of a servomotor 15 mounted outside the concrete block 100 surrounding the turbine casing 21. The servomotor 15 can operate all four needle valves 104 by means of interconnecting rods 103 and levers 24, 241. A sliding cylindrical valve 105 controls a number of outwardly slanting ports from the supply duct to the nozzle. The valve 105 is controlled by water servomotor pistons 11 to which water under pressure is supplied through pipes containing adjustable orifices 10. The pistons 11 contain ducts 111 controlled by steering pins 13. The pins 13 are connected to levers 19 pivoted on the servomotor 15, the other end of the levers being connected to a dashpot piston 16. A pin 17 allows the area of the orifice 14 in the dashpot piston to be adjusted. For an increase in load the governor opens the nozzles 104. Since the discharge regulator valve is closed, it stays at rest together with the dashpot piston 16. For a sudden drop in load, the governor rapidly closes the nozzles 104 by means of the servomotors 15. Initially, this causes the dashpot piston 16 to move and actuate the steering pins 13 so as to open the passages 111. This causes the regulator valve 105 to open. The degree of opening of the valve 105 may be made adjustable by means of eccentric pins in the levers 19, and may be made to correspond exactly to the degree of closure of the nozzles 104. When the discharge through the nozzles corresponds again to the new load, oil pressure acting on the right-hand side of the piston causes it to move and close the regulator valve again. The closing time is controlled by the lead-off screw 17.

Abstract: 492,331. Cables ; joints. STANDARD TELEPHONES & CABLES, Ltd., and WEBB, J. K. March 19, 1937, No. 29980. Divided out of 492,324. [Classes 36 and 38 (i)] Liquid-resisting barriers (stop joints, plugs, or terminations) are formed in impregnated multicore cables by removing the wormings from between the cores, filling the spaces so formed with a liquid or plastic material which solidifies, and thereafter forming a barrier of polymerized material in the insulation directly surrounding the cores. In an H-type cable, having screened cores, the spaces may be filled with metal, whereas in belted cables insulating- material must be employed. The method may be employed in connection with the barriers described in Specifications 429,611, 449,868, 460,031, or in combination with the method described in Specification 492,324, or in the preparation of joints using paper tapes impregnated with monomeric styrene. In the preparation of a plug in an H- type cable, the sheath armouring and wormings are removed, chilling boxes disposed at each side of the plug position and a sleeve 1, Figs. 1, 8, having filling holes provided. The cores are separated from each other by paper rolls 5 and from the sleeve by lengths 10 of copper or insulating- material. The sleeve is then filled with plumbers' metal, the flanges 11, 12 cut down and a wipe applied thereto. Nipples 21, 22 are then inserted, the chilling boxes filled with carbon dioxide snow and solvent circulated from a reservoir 24, solvent being withdrawn at 22, condensed at 28 and collected in the vessel 31. Prior to introducing the solvent, the sleeve is heated at 110‹ C. by means of a coil 35. After boiling off solvent, styrene is introduced into the reservoir 24 and pressure applied thereto, the sleeve being heated to polymerize the styrene. In the preparation of a joint, Figs. 11, 13, after completion of the core insulation and screening in the usual way, fittings 42 having nipples 43 are mounted to slide on the cores, a sleeve 1 plumbed in position and metal poured in through holes which are then sealed at 15<1>, 17<1>. Vacuum is then applied to the joint by means of the pump 34 connected to the nipples 21, 22, benzene flushed through each core first separately and then together and styrene applied similarly. Polymerization is then effected by heating the joint by means of a coil, the nipples removed and the holes in the sheath filled or sealed. Impregnated tapes may be soaked with monomeric styrene for use in building up the joints.

Abstract: 648,090. Exciting dynamo-electric machines. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Nov. 19, 1948, No. 30144. Convention date, Nov. 29, 1947. [Class 35] [Also in Group XXXVII] A hoist motor M is supplied from a variable voltage generator G having a control field winding 8 adjustably excited from a potentiometer 13 which is connected to a direct-current exciter E through a reversing switch 14. A motor field winding 3 is supplied at constant voltage by the exciter, a cumulative field winding 4 being excited from alternating- current mains through a rectifier 15 and the main coil 16 of a saturable reactor 17, the control coil 18 of which is connected, in series with an adjustable reactance coil 20, across a resistor 19 in the armature circuit of the hoist motor. A desired drooping speed-torque characteristic of the motor is obtained since the excitation of the coil 18 increases when the motor armature current becomes greater, the reactance of the coil 16 being reduced to provide heavier excitation for the field winding 4. The generator G has a shunt field winding 7 which is additive with regard to the field winding 8, and a series field winding 6 which opposes it. When the load is over-hauling the hoist motor acts as a series generator, stable operation being afforded by the relatively large time-constant of the coils 18 and 20. In a modification (Fig. 3, not shown), the field windings 3 and 4 are connected in opposite branches of a bridge circuit, the other arms of which comprise resistors. This circuit is so energized that the windings 3, 4, have a constant excitation component and a cumulative variable component derived from the rectifier 15.
