Title: Liquid resistor apparatus
IPC: H01C10/02
Filed: 1970-08-27
Abstract: 1324861 Variable liquid resistors N R BEYRARD 27 Aug 1970 [27 Aug 1969] 41401/70 Heading HIS Pressure developed in a vapour generator is used to alter the effective cross-section of the current path between two electrodes by either varying their depth of immersion in a liquid (Fig. 2) or inserting an insulating plate between them (Fig. 3). In the first embodiment (Fig. 2) a pulsed electric current operating a valve 8 releases liquid which falls on a heated dish 7 and vaporizes, the resulting increase in pressure in the vapour generator 6 inflating the bellows 5 which raises rods 2a, 3a, to reduce the depth of immersion of the electrodes 2, 3. Alternatively the bellows 5 may be replaced by a piston-andcylinder arrangement. A safety valve 9 prevents excess pressure from developing in the vapour generator, and cooling fins (11, Fig. 1, not shown) encourage condensation, the liquid then escaping through capillary drainage means 10. In another embodiment (Fig. 3) the vapour is generated by a current passing between electrodes 16, 17, partially immersed in liquid. The bellows 5A, 5B raise and lower an insulating partition 15 to alter the effective surface area of the electrodes (2, 3, Fig. 4) which are held about 1 cm. apart. By suitably shaping the electrodes (2c, 3c) the change in resistance caused by moving the partition may follow a chosen non-linear law. Distilled water is used as the liquid in both embodiments, and as another alternative the level of the water may be varied while keeping the electrodes stationary. When fully extended the bellows can be made to actuate a switch to short-circuit the electrodes after, for example, having been used in starting up an asynchronous motor.

[Also in Division A1] A rest-bar, for the draw-bar 9 of a tractordrawn, wheeled agricultural implement (see also Division Al), comprises a ground-engaging sprag 37 pivoted to the drawbar about a horizontal pivot 35 and carrying a locking member in the form of a pin 45 which extends parallel to the pivot 35 and is movable, against resilient opposition, in a direction transverse to its length, the draw-bar 9 carrying stops engageable by the pin to hold the sprag in an operative or inoperative position (shown in full and dotted lines) in the first of which the sprag and drawbar co-operate with the implement-wheels to hold the implement in an upright position. In Fig. 6, the pin is carried by a U-shaped stirrup 36 integral with the sprag, and is hairpin-shaped being manually movable in a slot 39 in the stirrup, to release the latter to move about its pivot 35, the pin springing back to engage the opposite side of a fixed bracket 33, when the alternative position of the sprag is reached.

Filed: 1973-09-07
Abstract: 1437219 Wells &c REGAN OFFSHORE INTERNATIONAL INC 7 Sept 1973 42271/ 73-Heading E1F A well tool 55 is run into a well 11 by rotatably connecting the tool to a part 70 of a coupling 10 having another part 60 connected to a running string 50, locking the part 70 to the tool by moving the part 60, landing the tool on a shoulder 24 in a wellhead 15 to move the part 60 relative to the part 70 to unlock the tool from the part 70, and by rotating the part 70 to release the tool from the coupling. The tool is a casing head carrying casing 59 which is rotated to distribute the cement during cementing of the casing in the well. The wellhead comprises a drilling template 16, casing 21 and a guide-frame 20, a Christmas tree 30 having guides 31, 38 and a protrusion 32 engaging the frame. A guide 41 engaging the frame has a coupling 43 connecting a blowout preventer 37 on the tree with a hanger support tool 44 connected to a marine riser 48. A running tool 53, located between the string and the coupling, is first supported by dogs 47 in the tool 44. After the string, tool 53, coupling, hanger and casing have been rotated in a right hand direction to distribute the cement which is supplied by a pipe 39, the dogs are released and the tool 53 lands on a seat 46 in the tool 44 and the casing hanger lands on the shoulder 24. The landing of the hanger results in the member 60 telescoping within the member 70, the members being rotatably connected by splines 63, 75. A drive ring 90 having splines 107 engaging splines 106 on the member 60 and having teeth 92 engaging the hanger prevents relative rotation between the member 70 and the hanger until the hanger is landed and the members telescoped to disengage the splines 106, 107. As the threads connecting the hanger to the member 70 are left handed and all the other threads in the running apparatus are right handed, rotation of the string in the right hand direction disconnects the hanger from the coupling.

The handle 16 of the lid is a trough in which the bail rests when the lid is raised and guide members 24, for replacement of the lid, are formed by pressed metal sheets secured to the sides of the bin. The limbs 19 are threaded through loops 17 and 23 formed by bent over tangs of plates secured to the sides of the lid and of the bin and bars to assist in emptying the bin are secured beneath the recessed base 11. In modifications the guides are replaced by a noise-reducing ring of fibre-glass of tapered section and of identifying colour, and the lid, bail and loops 17 and 23 are plastic-coated.
