Title: Improvements in or relating to Hydraulic Machines for Use either as a Pump or as a Turbine
IPC: F03B3/10
Filed: 1967-12-04
Abstract: 1,193,329. Hydraulic pump-turbines, VEREINIGTE OSTERREICHISCHE EISEN-und STAHLWERKE A.G. Dec.4, 1967 [Dec. 15, 1966], No.55121/67. Heading F1T. A hydraulic machine which can be used alternately as a pump or as a turbine has a Francis type rotor with blades each consisting of a non-adjustable part 4 and an adjustable part 5 pivotable about an axis 6 inclined at an angle of 30 to 60 degrees to the rotor axis 7. Depending upon whether the machine is to be operated in turbine or pump mode, the adjustable blade parts 5 are moved manually or automatically in either direction from the basic position shown in full lines in Fig. 2 to a broken line position which does not normally exceed 10 degrees from the basic. However to prevent runaway or for starting the machine prior to pumping operation, the parts 5 are movable into a position 'S' in which the flow passages between the blades are completely closed. The blade pivot pins 8, 9 are mounted in bearings in the rotor shrouds 2, 3 respectively, the outer bearings 10 being of plastics material. Fixed or adjustable stator vanes 1 are provided.

Abstract: 1333483 Rolling mills BLAW-KNOX FOUNDRY & MILL MACHINERY Inc 30 Nov 1971 [30 Nov 1970] 55614/71 Heading B3M A rolling mill is provided with an assembly for changing its work rolls, 11 and 12, Fig. 3, the assembly including rails 18 which extend between the windows of the mill (Fig. 1, in plan), and a roll-changing carriage 26 located beside the mill. To change the rolls 11 and 12, the rails 18 are raised to the position in Fig. 3 in which the lower roll chocks 16 are suspended by extensible rods 20 from the upper chocks 15. In this position, wheels 22 on the ends of the rods are aligned with rails 28 on the carriage 26. The rolls are then withdrawn from the mill by an hydraulically or motor-driven latch assembly 30.  The carriage 26 is then shifted parallel to the rolling line until a replacement set of rolls 11<SP>1</SP>, 12<SP>1</SP> is aligned with the mill, the latch assembly inserting the new rolls into the mill. The guide rails 29 and 29<SP>1</SP> along which the latch assembly moves are provided at their ends adjacent the mill with curved or straight portions to help the assembly engage or disengage the rolls. The bed 24 on which the carriage 26 rests may be fixed or may be movable towards or away from the mill. Additionally, the bed may be raisable by screws or levers, if this is necessary, to align the rails 28 with the mill. The rams 19a for raising the rails 18 may serve for balancing the upper work roll 11.

Abstract: 1485798 Lasers COMPAGNIE GENERALE D'ELECTRICITE 24 Dec 1974 [27 Dec 1973] 55699/74 Heading H1C In a progressively-excited gas laser in which a parabolically-ended transmission line formed by two metallic layers 2, 3 spaced by an insulating layer 1 includes an inclined discharge slot 4 containing a flowing laser active gas, the line is mounted on a substantially thicker plate 9 having a slot 11 linked by communicating ducts 12 with the inclined discharge slot, recessed seals 14 being provided between the ducted region of the plate and the transmission line. The discharge slot is overlaid by metallic blocks 5, 6 and is enclosed by an insulating cover 7. The assembly is mounted on a base-plate 10. In use, pumping is initiated by a point discharge at the parabolic focus F, and since forward transmission is prevented by an arcuate slot 15, a plane wave front is produced by reflection at the parabolic edge which progressively intersects the inclined discharge slot.

Title: Arc welding apparatus for welding a tube to a tube plate
IPC: B23K9/028
Filed: 1967-12-22
Abstract: 1,212,190. Welding by fusion. FOSTER WHEELER CORP. 22 Dec., 1967 [23 Dec., 1966], No. 58416/67. Heading B3R. In apparatus for multi-pass arc-welding a tube T to a tube plate S, the electrode 32 is moved axially of the tube T after completion of the first pass. An argon-shielded tungsten electrode arc-welding torch 30 is angularly adjustably mounted on an insulating block 38 slidable on but non-rotatably carried by a tubular member 28 fixed in an insulating sleeve 60 journalled in a housing 68. The block 38 is urged by a spring 54 against an adjustable ring 52 threaded on the tubular member 28. The tubular member 28 and so the torch 30 are rotated by a motor M1 through a gear-box 134 and a worm-drive 116. The motor M1, the gear-box 134 and the housing 168 are mounted on an arm 20 slidable horizontally in a mounting which is vertically movable on a supporting stand 22. The arm 20 may be moved by a rack-and-pinion device to insert in the tube T to be welded a mandrel 180 of copper or brass detachably secured to the end of a hollow shaft 26 passing through the tubular member. Cooling water is fed from a fixture 174 on the shaft 26 through a pipe 168 in the shaft 26 to the mandrel 180. A wire feed device on the block 36 feeds filler wire from a reel 270 through a guide 276. Argon is fed through a bore 94 in the housing 68 to an annular space 98 communicating with a conduit 104 rotating with and connected to the torch 30. Welding current is fed through a brush and slip ring arrangement 66 and slip rings 62, 64 supply current to the feed motor M3. The welding sequence is automatically controlled. After the first weld pass has been completed a motor drives a gear sector under the control of limit switches to rotate a gear 202 through about 90 degrees. The gear 202 abuts the tubular member 28 and is provided with a cam surface engaging a similar cam surface on a member 200 non-rotatably secured by a nut 206 on the shaft 26. On rotation of the gear 202 a spring 256 moves the tubular member 28 relative to the shaft 26 to position the torch 30 for the second welding pass. When the second pass is completed, the gear 202 and the tubular member 208 are returned to their starting positions. The filler wire may be fed during both welding passes or during only the second pass.

Chamber 14 is a conditioning chamber with a plurality of discharge pipes 24 and 25 with openings for discharging the conditioner, e.g. steam as jets 26 and 27 into the chamber 14 particularly as the garment passes between the openings 18 and 20. The second chamber 16 is a drying chamber with a blower 60 which forces air through a conduit 62 and over heat exchanger 64 where it is heated, and from discharge opening 66 on to the garment supported on the conveyor 30 and with a return 68. Means are provided for moving the first and second (screw type) conveyors at synchronized speeds. There is also provided a control to sense if a garment should fall from either conveyor 30 or 45 within the conditioning chamber 14 which then responds to stop the steam discharge. To do this a string 70 is suspended above the floor between the opposite walls of the chamber 14 where one end is tied to and actuates a sensitive microswitch 72 which switch in turn is connected in an appropriate control circuit. Photocell units 86 and 88 are located spanning the inlet opening 18 and are connected in an appropriate control to start the conditioning cycle automatically as a garment passes into the finisher and breaks the beam.

Abstract: 749,624. Instruments for deaf persons. AMERICAN DANISH OTICON CORPORATION. July 17, 1952 [July 18, 1951], No. 18141/52. Class 40 (4). A hearing aid comprises an armature secured to the exterior casing and resiliently supporting an electromagnetic system of relatively large mass so that energization of the system vibrates the casing. An annular magnet 134 is secured to a pole-piece 132 cut away at 138 to allow passage for the leads 120, 122 to the coil 130. The armature 152 is relatively thick at its centre where it is secured by a screw 156 to the casing 44. The armature has three radial arms 160, 170, 180, Fig. 5, carrying arcuate portions 162, 172, 182, the ends of which support the electromagnetic system by means of screws 164, 174, 184 engaging a ring 142 of non- magnetic material fixed to the magnet 134. Due to the inertia of the magnet, energization of the coil vibrates the armature 152 and casing, the part 24 transmitting the vibrations to the head of the user. A plug connection to the instrument is effected through sockets 64, the pins of the plug engaging terminal strips 106.
