Title: Well tool with retention sleeve
IPC: E21B23/00
Filed: 1975-12-10
Abstract: 1521498 Well tool coverings DRESSER INDUSTRIES INC 10 Dec 1975 [20 Dec 1974] 50674/75 Heading E1F A well tool such as a packer may be protected from adverse environments encountered during its location in the well bore by providing a cover 17, the cover being formed by placing the well tool in a sleeve of shrinkable elastomeric material, and then shrinking the material so that the sleeve becomes tightly fitted on the tool. The material may be heatshrinkable e.g. polyolefin, polyvinyl chloride or neoprene, or it may be shrinkable by chemical reaction or by applying an electric current. Preferably it retains chemical and thermal stability after shrinkage, and a degree of elasticity so that the cover 17 elastically retains in position such movable or expandable elements as gripping member 12 and anchor buttons 13. After location and hydraulic activation of the tool, the force applied to such elements 12, 13 causes them to cut through the cover 17 to grip the casing wall. The cover 17 is also elastic enough to allow radial expansion of the then axially compressed resilient packer elements 15. A cut-out portion of the cover 17 may be provided in the region of e.g. the gripping portion of the member 12, less hydraulic force being then required for actuation. The cover may be removed from a located well tool by dissolving it in a solvent pumped down the well bore.

An oxidized mild steel melt, prepared in a steel making furnace or converter at a temperature above 1600‹ C. e. g. where oxygen is blown into the melt and containing a maximum of 0À03% C, is vacuum decarburized in a ladle or whilst being poured from ladle to ladle to reduce the maximum C content to 0À012% prior to final casting e. g. in an ingot mould. Any excess O is removed from the steel with a deoxidizer e. g. Al and/or Si (as Fe-Si) at the end of the vacuum treatment during which alloying additions may be also made e.g. Cr (as Fe-Cr, Si-Cr or CrO 3 ). The initial steel may be a plain carbon or an alloy steel e. g. containing Ni or Co. The steel melt contains at least 0À08% O when Ni, Co or other Group 8 metal is less than 1%, or at least 0À055% O when Ni, Co or other Group 8 metal is 1% or more. For final steels with low P and S content, the initial steel is prepared in an electric furnace. The steelcontaining vessel may be filled with CO diluted with a neutral gas. Oxygen may be introduced into the melt during the vacuum treatment in the form of a blown oxidizing gas e. g. using a hollow stopper-rod and/or an oxide or a carbonate e. g. as lump or powder form. For 3À1% Si steels, the final ingots may be normalized at 850‹ C, cold rolled in two stages with intermediate anneal in dry H 2  at 925‹ C, and re-annealed in dry H 2  at 117‹ C. to obtain a cube-on-edge structure.

Abstract: 1,031,979. Windings for dynamo-electric machines. SOC. D'ELECTRONIQUE ET D'AUTOMATISME. Dec. 15, 1964 [Dec. 16, 1963; Oct. 22, 1964 (2)], No. 51066/64. Heading H2A. A printed winding having upper and lower coil conductors formed on either side of an insulating carrier has additional conductors formed on an adjacent part to complete the winding circuit. The winding may be used in linear form, or arcuate, or it may be bent round to form a drum winding. Hence, if the winding is to be bent round into a loop to form a drum winding, no (or few, Fig. 6) further connections are necessary at the join. In the Figure, the solid lines indicate the separation between conductors on the front face, dotted on the rear face. The front conductors are 1-39, the rear conductors 2-40. It is a wave winding. The tops of all the coils are connected through, e.g. by metallized holes in the carrier, and so are some of the lower ends, but the conductors at each end of the carrier have no corresponding conductor of the other side to connect to. Accordingly these conductors 31-39 and 32-40 are interconnected by longitudinal conductors 221-239 to complete the wave winding. These longitudinal conductors are in laterally spaced groups so that if the carrier is folded about its longitudinal axis, these conductors overlie the coil endloops and do not interfere with the pole-flux (see also Fig. 14, not shown). In modifications, the interconnections are not made by passive conductors but, at least partly (Fig. 7), by an additional winding lying under additional field poles suitably axially spaced from those which excite the main winding (Fig. 3, not shown). Thus in Fig. 1 (not shown), the main winding, a series-wave winding of progressive pitch, is interconnected to a further series wave winding, this one being of regressive pitch. Alternatively, the additional winding may be a regressive-lap winding (Fig. 5). If the winding is to be bent round into a drum a connection may be made at the end conductor to simplify the interconnecting conductors (Fig. 6). The carrier may have metallized perforated edges by which it is mounted on toothed discs (Fig. 15) in either drum or linear form. In the case of lap windings (Fig. 19, not shown), a single additional connector 103, 104 is sufficient, or (Figs. 20-22), additional conductors within the winding space may be used. Alternatively a progressive lap winding may be linked to a regressive one, as with the wave windings.

Abstract: 1,093,078. Cooling reactors. ATOMENERGI A.B. Dec. 15. 1964, No. 51072/64. Heading G6C. In a pressurized water reactor, boiling is prevented by the supply of steam to the space above the reactor coolant surface. The pressurizing steam is supplied to the reactor pressure vessel from an external electricallyheated boiler. Reactor pressure control is effected by adjustment of the flow of cold water into the pressure vessel through a spray. A thermal barrier is interposed between the liquid and vapour spaces in the pressure vessel by a horizontal partition wall. In order to control the pH value of the coolant water, nitrogen may be supplied to the vapour space. The thermodynamic conditions necessary are that the electric boiler steam is saturated and is at a higher temperature then the reactor coolant.

Abstract: 1283800 High voltage switches; fluid actuation of switches COQ NV 28 Oct 1970 [4 Nov l969] 51255/70 Heading H1N An earthing switch comprises fixed contacts 2, 3 separated by insulation 1 and having a movable contact rod 4 connected to earth via contact 2, metal block 6, cover 7 and earthed metal envelope 5, the rod being actuated by a piston 9 attached to it which moves within double-acting cylinder 8 between end stops 10 and 11, and is connected to a screwed shaft 36 having a biasing arrangement at its free end to bias the piston into its two end positions. Valve housings 18 and 19, which control the piston 9, are connected to cylinder chambers 12, 13 respectively via chambers 14, 15 and passages 16, 17. In Fig. 3 the chamber 20 of housing 18 is connected by valve 21 either with the atmosphere via passage 22 or with chamber 24, the valve being operated by piston 25 loaded by spring 26. Cylinder chamber 27 can either be connected to chamber 24 or to atmosphere via a three-way valve 30. Chamber 24 is connected to chamber 35 through passages 32, 33, 34 which latter chamber is filled with compressed gas. In both piston end positions the valves in housings 18, 19 are in the position shown and both the cylinder chambers 12, 13 are under high pressure. For the operation of the switch the respective valve 30 is changed over so that either of the chambers 12, 13, connected to a respective valve chamber 27, is connected to atmosphere, thus causing the piston to move to the other end position. Screwed shaft 36 is mounted in the hollow contact rod and cooperates with rollers 40, which act as a nut, mounted in the piston 9. Piston 9 and rod 4 are locked against rotation by axial rods 41 such that on rotation of the screw 36, the piston and rod move axially, and vice versa. Mounted on end 36a of the screw is a locking disc 42 which co-operates with locking roller 43 mounted on an arm 45 loaded by spring 46, which arrangement, Fig. 2 (not shown), locks the piston in its respective end positions. The switch can be operated by a spanner, Fig. 4 (not shown), engaging projections 47. Locking disc 42 has marks (50, 51) which indicate the switch position through a casing window.

Abstract: 518,474. Cash registers; transfer mechanism. BATA AKCIOVA SPOLECNOST. July 1, 1938, No. 19618. Convention date, July 1, 1937. [Class 106 (i)]  In a differentially set and operated cash register, the manual rotation of setting discs sets indicator wheels and enters the amount into a totalizer, the denominational members of which are connected by differential gearing to permit simultaneous actuation and transfer. The machine is set and operated by rotatable discs 1, Fig. 1, flanges of which contain finger apertures through which numerals on stationary quadrants 6 are visible. The discs carry gear rings 4 permanently in mesh with totalizer actuating pinions 13' . . . 13<SP>3</SP> and normally in mesh with the pinions 11, ... 11 3  of indicator drums 12<SP>1</SP> . . . 12<SP>3</SP>. The discs are aligned in set position by rollers 7, Fig. 2, carried by spring-loaded levers 8 and engaging teeth on the inner peripheries of the rings 4. The drawer is released by a plunger 34. depression of which removes an offset lug 37 from the path of a stud 36 on the drawer. As the drawer opens, under the action of a spring 35, a lever 40, bearing against its inner end, rotates with its shaft 41 to interpose abutments beneath the left-hand ends of the aligning levers 8 and thus lock the discs in' set position. The drawer is closed manually and by a ramp 44 raises a roller 45 and plunger 47 to lift the pinions of the indicator drums out of mesh with the gear rings of the setting discs, whereupon the drums are zeroized by internal spiral springs. As the drawer Teaches closed position, the roller enters a recess 50 therein and the indicators are re-engaged, this movement being retarded by a dashpot 51 to ensure that the indicators have had time to zeroize. To prevent disengagement of the indicators upon the opening :of the drawer, the roller 45 is connected to the plunger 47 by a by-pass lever. A gong 55 is struck by a hammer 56 upon the opening of the drawer. The hammer is held against the action of a spring 58 by a latch 59, 60 that is disabled by a stud 62 on the drawer as the latter opens and is restored by the stud as the drawer closes. Totalizers; transfer mechanism.-The totalizer actuating pinions 13<SP>1</SP>... 13<SP>3</SP> Fig. 1, are permanently in mesh with the gear rings 4 of the setting discs 1 which rotate in setting direction only.
