Title: Improvements in or relating to the welding of metal stubs to metal base members at curved surfaces thereof
Inventor: JONES JOHN EDWARD HERBERT
IPC: B23Q35/10
Filed: 1958-02-28
Abstract: 871,459. Welding by fusion. BABCOCK & WILCOX Ltd. Feb. 25, 1959 [Feb. 28, 1958], No. 6554/58. Class 83 (4). Stubs are welded to a curved surface of a base member by rotating a welding head around the axis of the stub and at the same time moving the welding head axially of the stub under control of a cam shaped to correspond to the shape of the joint between the stub and the base member. A cylindrical box 3, Fig. 7, is prepared for welding the stubs 1 by boring holes 7. machining a part cylindrical surface 9 about an axis transverse to the axis of the box 3 and boring a flat-bottomed recess 13. A stub 1 is positioned with a flat-machined end 1A in the recess 13 and is tack-welded if necessary. The stub 1 may be incompletely bored to leave a partition 1B, Fig. 5, to facilitate hydraulic testing of the welds. The welding machine consists of a frame 31 supported on wheels 27 running on rails 29. One of the wheels has a manually releasable spring-loaded brake. A turn-table 23 mounted on rollers 33 in the frame 31 is rotatable at any required speed by an electric motor 43. The welding head 127 is carried by a bracket 113 on a tubular shaft 71 telescopically mounted on a rod 69 connected by universal couplings .65, 67 to an axle 61 depending from the centre of the turn-table 23. The shaft 71 which may be retained in an upper position by a latch 79 carries a pin 89 which when the shaft 71 is dropped may be engaged in a muff 103 which is secured over the end of the stub 1. Projections 105 on the end of the shaft 71 ride on a cam surface 107 of the muff 103 which surface is shaped to maintain the welding head 127 at correct spacing from the weld as the head 127 is rotated about the pin 89. An electrode reel and feeding device 133 on the turn-table feeds the electrode through flexible guide and contact tube 135 to which current is connected from a block 145 on the frame 31 by a slip-ring and brush arrangement. A flux retaining ring 151 which may be rigid or in the form of a flexible chain is placed around the joint which is covered by granular flux. The weld may be made in three runs with different starting points and with the electrode at 45, 35 and 55 degrees to the stub axis. Alternatively, a flux-coated electrode or a bare electrode using a shielding gas such as argon or carbon dioxide may be used. The current supply arrangements may dispense with the slip rings if a device mechanically limiting the number of rotations of the turn-table is used. Instead of using a driving motor the turn-table may be rotated manually through a governor-controlled gear reduction device. In a modification, the frame 31 is suspended from a crane.

Abstract: 994,704. Raising liquids by aerating an ascending column. U.S. INDUSTRIES Inc. Feb. 20, 1962 [Sept. 7, 1961], No. 6627/62. Heading F1R [Also in Division F2] A gas lift valve 24, Figs. 2, 3, normally controlling slugs of gas under pressure passing from a well casing through inlet 27 to outlet 16 to enter the well tubing and lift well fluids to the surface, is loaded towards its seat 28 by pressurised gas injected via valve 21 to above bellows 17 with or without spring loading, the valve having a surface, e.g. the shoulder between the plug port 32 and the surface 31 of the valve which is exposed to downstream pressure when the valve is closed, and a constant area flow restriction downstream from the surface, e.g. the space between the plug 32 and the wall 29 of the seat outlet, whereby when the valve is cracked open in response to a high upstream pressure, this upstream pressure suddenly acts on the surface upstream of the restriction and snaps the valve fully open. In the embodiment of Fig. 4 the upstream pressure acts within a hollow, stepped and chamfered valve 38 co-operating with a movable seat 36 guided at 36a in a spider having throttle opening 35a. With valve 38 open, reverse flow is prevented by seat 36 acting as a valve and closing on to valve 38 acting as a seat. Valve 24 may relieve tubing pressure into the casing. In a further embodiment, valve 38 is a solid, stepped and chamfered plug co-operating with a stepped seat with the normally higher pressure at 16a.
