Title: Improvements in or relating to Means for Gripping the Ends of Lenghts of Pipe or Tube.
Inventor: BRADDY HERBERT WILLIAM JOHN
IPC: F16L55/136
Filed: 1966-06-23
Abstract: 1,156,804. Pipe end fittings. BRITISH INSULATED CALLENDERS CONSTRUCTION CO. Ltd. 23 June, 1967 [23 June, 1966], No. 28207/66. Heading F2P. A pipe end fitting, which is adapted to be clamped to an end of a pipe for pulling the pipe e.g. into a tunnel formed by a mole plough and which is particularly suitable for use with rubber or plastics pipes, comprises a sleeve 4 which is a sliding fit over a pipe 8 to be gripped, a tubular body 5 that fits into the end of the pipe 8 and is split axially into at least two separate parts, e.g. three similar segments 13 as shown, means, e.g. a screw and nut mechanism 6 for urging the parts of the body 5 outwardly so that the end of the pipe is gripped between the body 5 and the sleeve 4 the mechanism 6 being accessible for operating by means located externally of the sleeve, and means, e.g. an attachment 7, mounted on the fitting for effecting direct, or indirect attachment to a pipe-pulling device. The sleeve 4 has an end plate 9 to which is fixed a domed 11 or, alternatively, a frustoconical member. The cup 4, 9 may be formed integrally with a domed end or the latter may be cast from aluminium and bolted in position. The segments 13 of the body 5 can be formed from a solid brass cylinder of approximately the inner diameter of the pipe 8 and be sawed, or milled, axially, the segments 13 being urged together by resilient bands 16 and seated on an annular plate 14 which has radially extending- slots which receive screws 15 screwed into the segments 13. The mechanism 6 comprises a screw-threaded rod 12 which threadedly engages a tapered collar 18 restrained against rotation by pins 19 which engage between segments, the rod 12 being secured in a clear bore through the plate 9 and the dome 11 by a nut 20 welded to the rod 12. On rotation of the rod 12 the collar 18, the segments 13, and a second tapered collar 23, which is freely slidable on the rod, are raised until the upper collar 23 engages the nut 20. Further rotation of the rod 12 causes the segments 13 to be urged uniformly outwardly into gripping engagement with the pipe 8. In an alternative mechanism the collars 18, 23 have right and left hand screw-threaded engagement respectively with the rod 12, the collars 18, 23 both being prevented from rotating by pins such as 19. In a further arrangement of the mechanism the rod 12 has screw-threaded engagment with the sleeve 4 and/or the dome 11 and the collars 18, 23 are not threaded on to the rod the nut 22 drawing the collar 18 into the body 5 as the rod is screwed out of the fitting. If a tube is resilient enough to take up the non-uniform expansion of the tubular body 5 the collar 23 may be omitted. By providing a tubular distance piece on the rod 12 and by lengthening the sleeve 4 the fitting can be used without grippng any threaded part at the end of a pipe.

Title: Improvements in and relating to vibration damping devices for elastic fluid turbines
IPC: F01D25/04
Filed: 1920-10-14
Abstract: 174,154. British Thomson - Houston Co,. Ltd., (General Electric Co.). Oct. 14, 1920. Dash-pots and fluid-friction vibration-dampers. -For damping the axial vibrations of turbine shafts, a thrust-absorbing member capable of axial movement is rigidly connected with the movable member of a dash-pot which is adapted to check quick motions but does not seriously interfere with slow motions, the thrust bearing and the dash-pot being so arranged relatively to one another that the lubricant of the thrust bearing cannot enter the dash-pot. The turbine shaft 7 is connected to a thrust disc 15 which, together with the bearing discs 19, is located within an axially movable thrust casing 11, 14 having trunnions connected by rods (not shown), with a yoke 27. This yoke engages the rod 31 of the piston 32 of a mercury dash-pot, which allows a slow transfer of mercury from one side of the piston to the other through the clearance between piston and cylinder. Mercury forced past the U-shaped packing 33 enters a chamber 37 in the head 30 of the dash-pot and flows upwards to a reservoir 40 which is open to the atmosphere and communicates with opposite sides of the piston 32 through pairs of inwardly opening valves 45. Should any mercury leak past the stuffing-box 34 it is caught in a container 43. The oil for the two sides of the thrust disc 15 is fed by a pipe 20 and discharged by a pipe 22, the duct 23 through which part of the oil escapes being arranged above the shaft and its bearing 17 to ensure a permanent supply of lubricant to the latter. The oil and mercury systems unite to restrict the axial movements of the shaft 7, but are maintained entirely separate. Specification 19169/12 is referred to.

Abstract: 1292890 Regulating I C engines SULZER BROS Ltd 16 June 1970 [27 June 1969] 29146/70 Heading F1B A speed-responsive fuel-pump control system of a Diesel engine, e.g. for marine propulsion, comprises a speed controller 1, Fig.1, which controls the fuel injection pump or pumps (not shown) via a servomotor 7. Reel 3 adjusts input lever 2 of the controller to the desired speed setting. Output lever 4 of the controller, via  link 5 and servomotor input lever 6 controls the position of the servomotor piston which, in turn, controls the fuel-pump via linkage 9, 11, 12, 13 and 15. A rod 23 and a lever 20 rigidly connected to lever 2 enable the controller to be bypassed so that the servomotor piston can be controlled directly by rod 3, e.g., during engine  start-up when the controller is temporaily inoperative, the lever 4 taking over control when the controller becomes operative. Thereafter the relative positions of the-lever 20 and rod 23 correspond to a greater fuel-flow than is called for by the controller 1 and thereby, for each position of input lever 2, set a limit to the adjustment of the input lever 6 in a direction towards higher fuel-flow. A rod 27 and a lever 25 rigidly connected to lever 4 enable the servomotor to be by-passed so that on failure of the latter the fuel-pump can be adjusted directly by the controller. Moreover, the rod 27 and lever 25 prevent the fuel-pump from being adjusted to the maximum fuel setting by tension spring 16 when the servomotor fails. The various lost-motion connections shown may be replaced by spring-biased connectors, Fig.2 (not shown).
