Title: Improvements in or relating to regulating nozzles for impulse turbines or needle valves
IPC: F03B15/20
Filed: 1957-10-10
Abstract: 842,940. Hydraulic turbines. VOITH G.m.b.H., J. M. Oct. 10, 1957 [Oct. 10, 1956; March 12, 1957], No. 31762/57. Class 110 (3). [Also in Group XXIX] A regulating nozzle for an impulse or free-jet turbine comprises a hollow regulating needle 1, Fig. 1, secured to a shank 4 slidable on a piston 60 fixed by its rod 7 to a cap 50 which is in turn secured to a guiding sleeve 5 carried on a spider 25 by the nozzle casing 3. The shank 4 is divided by a partition 15 into a front chamber A communicating through ports 9, 8 with pressure water controlled by the needle and a rear chamber B communicating through a pressure oil line 16 with a regulator (not shown). Alternatively pressure water may be admitted to the chamber A through a bore 22 in the piston rod 7 or through a duct 10 branched from the pipe through which the water flows and a port 11. Leakage water past the piston escapes through a duct 18. A loading spring 12 abuts plates 13, 14 moved by a shoulder 70 on the rod 7 and slidable on the rod 7 respectively. The plate 14 is engaged by an end flange 20 of the shank 4 until arrested by a stop collar 170. On the regulator decreasing the pressure in the chamber B the needle 1 begins to open; the pressure on the external cone face of the needle in an opening direction being opposed by oil pressure acting on the partition 15 and water pressure on the inner surface of the cone. The loading in the spring 12 is initially decreased since the plate 14 moves rearwards. When the plate 14 engages the stop collar 170 the partition 15 engages the plate 13 so that any further opening movement of the needle is progressively opposed by the spring 12 to compensate for the increased area of the needle subjected to water pressure in the opening direction. To close the needle the pressure of the oil in the chamber B is increased. A returning lever 19, spring-urged to engage the flange 20 is fitted. In a modification, pressure oil may be admitted to the space between the piston 60 and the partition 15 so that the partition 15 in effect becomes a doubleacting piston. In a further modification, pressure oil can be alternatively admitted and exhausted from opposite sides of the fixed piston 16, Fig. 3. Water pressure in this case opposing the opening of the needle acts on an annular surface 600a of the cover 600 of the shank 4. In this embodiment sealing rings between the guide sleeve 5 and shank 4 may be omitted.

Patent GB-806727-A (GB)
Title: Process and apparatus for sweetening water
IPC: C02F1/22
Filed: 1956-10-19
Abstract: A continuous process for sweetening water comprises subjecting solute-containing crude water, pre-cooled to a temperature near its freezing-point, to partial evaporation under substantially adiabatic conditions while held under reduced pressure, so that a portion of the water is frozen, and contacting the ice, freed of mother liquor and under reduced pressure, with the water vapour formed in the evaporation stage so that the ice is melted and the water vapour is condensed to provide the desired sweet water, the withdrawn mother liquor and the sweet water being used to pre-cool the incoming crude water by heat exchange.  The process may be applied to the purification of sea water, brackish <PICT:0806727/III/1> water, industrial brines and waste liquors from the fruit juice or sugar industries.  In Fig. 1, crude water from tank 2 is pre-cooled by passage through heat-exchange 4 and is then fed by conduit 3 to evaporator 1.  Water vapour is withdrawn from evaporator 1 by means of blower 11 and introduced into ice-collecting vessel 7 and melting vessel 14 through pipes 13 and 13a respectively.  A partition wall 8 between evaporator 1 and ice-collecting vessel 7 is provided with a series of swan-neck pipes through which a mixture of ice and mother liquor passes, providing liquid seals which prevent the passage of water vapour. Conveyer belt 15 carries ice through vessel 7 into vessel 14, and filters off mother liquor, which is pumped by pump 20 through pipe 21 to tank 22.  Sweet water from the melted ice and condensed water vapour is pumped by pump 24 through pipe 34 and sprayed into condenser 31, while water vapour is withdrawn from vessel 14 by means of two-stage blower 26, 27 and supplied to condenser 31. Further water vapour is condensed in condenser 31 and sweet water is delivered through pipe 32 to tank 33.  Vacuum pump 37 maintains reduced pressure throughout the apparatus, while vessels 1, 7 and 14 and all conduits are heat-insulated.  Further apparatus is described in which the use of blowers 11 and 26, 27 and of vacuum pump 37 is avoided with the aid of steam ejectors.

Abstract: 857,373. Metal vapour lamps. PHILIPS ELECTRICAL INDUSTRIES Ltd. Sept. 23, 1959 [Sept. 26, 1958], No. 32395/59. Class 39(1). In a holder 2, for a liquid cooled superhigh-pressure metal vapour discharge tube, provided with optical means such as a mirror 204 to co-operate with the discharge path, the position of the discharge tube in the mounting 3 is axially maintained by a stuffing ring 212 of resilient material, and axially regulated by a screwthreaded member 216 which abuts against the tube at 108, the tube being pressed " downwards " by resilient means 316. The leads 109, 110 to discharge electrodes 105, 106 respectively engage slot 201 in contact pin 202 and abut against spring- loaded contact 302. The cylindrical mirror 204 is mounted on shell 203 which is attached to the outer casing of the mounting 304. The contact pin 202 screws into member 216 which itself is screwed onto flange 210 of the holder base 206. As this member 216 is screwed on to the base 206, the discharge tube rises towards end 317 of the mounting, and the abutment of the tube against member 302 causes a valve 313- 314 to open, thus allowing a current of cooling liquid to flow through the device by the path 308-307- 312-2-219-308A-309. If the discharge tube has to be replaced, the member 216 is unscrewed and the spring 316 closes the valve before the tube actually becomes free of the mounting thus reducing the amount of fluid that is spilt in the operation. The discharge tube and holder are assembled in the mounting so that the tube is adjacent to a window, Fig. 2 (not shown).
