Filed: 1970-06-02
Abstract: 1,270,044. Wells. VETCO OFFSHORE INDUSTRIES Inc. 2 June, 1970 [22 Oct., 1969], No. 26507/70. Heading E1F. In a method of hanging multiple strings of tubing in an underwater well, a tubing hanger C, Fig. 1, supporting tubing string Tl, is landed on shoulder 9 of casing hanger B in well head A, a spring loaded rib 24 engaging well head slot 25 to orient hanger C. Tapered sleeve 21 is then lowered to move dogs 10 sideways into groove 8 to anchor hanger C in hanger B. Tubing string T2, supported by mandrel 37, running tool 47 and tubing 57, is lowered through bore 35 until mandrel shoulder 42 seats on shoulder 43. Inherently contractible ring 46 is expanded into groove 45 by shoulder 42, and kept expanded by running tool flange 53. Tubing 57 and running tool 47 are then rotated until, Fig. 3, flange 53 is raised above ring 46, allowing the ring to contract into bore 35 to prevent upward movement of mandrel 37. Running tool 47 may then be unscrewed and_withdrawn. In an alternative embodiment, Fig. 4, inherently expansible ring 146 is held contracted between the tapered end flange 146b of running tool 147 and mandrel 137. The unscrewing of tool 147 from seated mandrel 137 raises flange 146b and allows ring 146 to expand into groove 145, thus preventing upward movement of mandrel 137. In both embodiments the ring is moved into its associated groove when the running tool is screwed onto the seated mandrel, thus allowing tubing string T2 to be withdrawn.

Title: Process and Apparatus for Welding of C-Shaped Workpieces
Inventor: WUEST TONI
IPC: B21L3/02
Filed: 1967-06-09
Abstract: 1,191,655. Resistance welding. P. ESSER. [trading as MEYER, ROTH & PASTOR]. 9 June, 1967, No. 26799/67. Heading B3R. In a process for electric resistance or flash butt welding of a C-shaped workpiece 16, the latter is placed on a saddle, is centred on the saddle by upsetting tools 11, 12, Figs. 2, 3, and electrodes 18-21 grip the ends 17 of the workpiece and move them towards each other for heating up when resistance welding, or provide relative alternating movement when flash butt welding, whilst the tools 11, 12 are retracted, and then the tools 11, 12 are traversed to provide the upsetting. Tool 11 is fixed in the machine frame 10, and tool 12 can be moved relative to tool 11 by a fluid piston 13. Electrodes 18, 19, and 20, 21, are pivoted to yokes 34 and 63 respectively, the yokes being movable by fluid pressure pistons 35, 61. The grip of the electrodes is effected by pistons 22, 23, 41, 42, pistons 23 and 41 being lockable in the required position by fluid pistons 54 and 56. In operation, with the workpiece 16 on the saddle, fluid pressure is supplied to piston 14 so as to move tool 12 up to the work and centre the latter on the saddle. Pistons 22, 23, 41, 42 are actuated, and the electrodes 18-21 grip the workpiece. Pistons 54, 56 are supplied with fluid, and the pistons 23, 41 are clamped. Fluid is supplied to pistons 35, 61, through pipes 38, 65, and the yokes 34, 63 are moved towards each other until adjustable stops 39, 66 abut the frames 10, 40. Due to the workpiece being clamped by the electrodes, and also due to tool 11 being fixed, the tool 12 is moved by a distance equal to the sum of the movement of the yokes, and a gap is produced between the tools 11, 12 and the workpiece, Fig. 3. If desired the saddle may be retracted. The pressure is increased in pipe 69 to move the piston 14 in one direction when resistance welding, whilst for flash butt welding pressure in pipe 69 alternates with pressure in pipe 68, to thus provide movement in two directions. With the welding current switched on, the ends 17 of the workpiece are heated and the welding process is initiated. The upsetting is carried out by increasing the pressure in pipe 69 so as to move the piston 14 until stop 70 abuts cylinder 15. The upsetting can be effected by electrodes 18- 21 alone, by the electrodes in conjunction with tools 11, 12, or by the tools alone.

Spindle driving means 22 comprises a tube (95) Fig. 7 (not shown) fixed to support (23) and containing a rotatable spindle shaft carrying the spindle head (51) with a spring-loaded latch engaging the selected reel. For re-winding, the spindle shaft is driven through a slipping clutch by belt-driven pulley (103), the drive being disengaged to permit free rotation of the reel. The clutch is controlled by a plate (121), actuated by the control cam-shaft (72), and is briefly engaged before drive (64) operates to tighten the film coil turns. The cartridge rack has spaced legs 52, Fig. 1, which are engaged by indexing mechanism (53), Fig. 7 (not shown), operated by cam-shaft (72). The racks are interchangeable and manual override is provided. Control assembly (56) includes the drive-and cam-shafts (73, 72), the indexing means, and the film extraction means, and is powered by motor (82). A rotary switch comprising contact plate (91) and rotary contact (92) on cam-shaft (72) controls the electrical circuits which operate the cam-shaft clutch solenoid, the spindle shaft clutch actuator, the film-threading mechanism, an empty-reject switch operative when no cartridge is encountered by the threading mechanism, a gate switch sensing the arrival of the film end at the projector gate. Coding notches in the cartridges, for example, to indicate whether a sound film is within, are sensed by a switch which switches on the sound reproduction means. Framing speed is selected by manually operable knob 15. A spring-loaded snubber detects increasing film tension after projection and switches on the re-wind drive to the spindle shaft.

Filed: 1973-06-06
Abstract: 1425727 Semiconductor devices PLESSEY CO Ltd 15 May 1974 [6 June 1973] 26952/73 Heading H1K A non-volatile semiconductor memory device comprises a p type Si layer 1 on a p type substrate 2, an n type surface region 3 and an n<SP>+</SP> type region 4 having a first part 5 adjacent the layer/substrate interface and a second part 6 connecting the first part 5 to the surface of layer 1. On the layer 1 between the regions 3 and 4 and partially overlapping the former is a thin (<30Š) oxide layer 7 covered by a nitride layer 8, and an electrode 9 overlies the nitride layer 8 and extends on to the region 3, with which it forms a Schottky barrier contact. Fig. 1 illustrates the OFF condition, with no set charge at the oxide/nitride interface 7/8 and only a very small leakage current between the electrode 9 and the earthed region 4 for small positive or negative potentials on the electrode 9. The ON condition is obtained by applying a temporary large negative potential to the electrode 9; this causes electrons trapped at the interface 7 to tunnel through the oxide 7 leaving a set positive charge at the interface 7/8, which charge induces a depletion region (12) Fig. 2 (not shown) in the layer 1 beneath the oxide 7. This depletion region (12) merges with that 11 associated with the junction between part 5 of region 4 and layer 1, and permits a large space-charge-limited current to flow between region 4 and electrode 9 on application of a small positive potential to the latter. The device is returned to its OFF condition by the application of a large positive potential to electrode 9, causing electrons to tunnel back through the oxide 7 to the interface 7/8.
