Title: Improvements in or relating to Composite Tubular Structures and the Application Thereof to Thermionic Converters.
IPC: G21C3/40
Filed: 1966-09-05
Abstract: 1,152,734. Making composite tubes. COMMISSARIAT A L'ENERGIE ATOMIQUE. 5 Sept., 1966 [17 Sept., 1965], No. 39656/66. Heading B3A. [Also in Divisions F2 and H1] A composite tubular structure comprising two coaxial cylindrical cases 2, 6 of heat resistant metal or alloy which are electrically and thermally insulated from each other by an intermediate layer 7 of a powdered material, such as a heat-resistant oxide, is made by mounting the two cases one in the other with an air gap therebetween, introducing the oxide material into the gap and co-forging the composite structure at such a high temperature that upon cooling and for all subsequent use the outer case remains under elastic tension. The interposition of the powdered material may be effected by using partially or wholly pre-sintered rings of the material which are broken up to give a powder during shrinkage. Alternatively the powder may be longitudinally compressed between the two cases by annular pistons, either when hot or cold. A further alternative is to cover the inner ease with the material by its projection using a plasma blowpipe or schoop gun and thereafter grinding to size. The coforging operation may be magneto-forging or isostatic pressing or rolling, carried out on a reducing machine. Different elongations of the inner and outer cases may be avoided by suitable mounting. A series of these structures may be stacked to form part of a thermionic converter, Fig. 2 (not shown).

Abstract: 940,560. Controlling clutches. E. C. HAHN, [trading as INDEX-WERKE KOMM.-GES. HAHN & TESSKY]. Nov. 17, 1961 [Dec. 17, 1960], No. 41232/61. Heading F2L. The control shaft of an automatic lathe is driven from an auxiliary shaft coupled by a first clutch to a driving shaft and to manual operating means by a second clutch, the two clutches being interconnected for the engagement of one only at a time. The auxiliary shaft 30, which drives the control shaft of the lathe through gear 28, may be driven by a belt 36 through an electromagnetic clutch 40 or by a hand wheel 37 (for toolsetting) through a dog clutch 42 operated by a solenoid 52, and may be stopped by an electromagnetic brake 55. After closure of a main switch 73, closure of a control switch 87 energizes a driving motor and a relay S which closes a holding switch S1, clutch energizing switch SIII and brake hold-out switch SIV and opens a time relay 2 and clutch switch SV, thus allowing power drive of the shaft 30. Opening the main switch de-energizes the relay S to release the clutch 40, engage the brake 55 and engage the clutch 42; at the same time the time relay Z is energized to close a switch ZI which releases the brake 55 after a short interval and allows manual rotation of the shaft 30. The shaft may be power driven for toolsetting by operation of a switch 77 which is independent of the holding switch SI.

Title: Method and apparatus for testing wells

Filed: 1971-09-06
Abstract: 1323243 Wells &c HALLIBURTON CO 6 Sept 1971 [14 Sept 1970] 41451/71 Heading E1F In the use of a test string 10 to sample fluid from a formation 5 the pressure on fluid in the annulus 16 about the test string is maintained at a low value and the string is closed to the formation, the pressure is increased to open the string to permit flow of formation fluid through the string, and then the pressure is altered to close the string to the formation and trap a formation fluid sample in the string. The string for a subaqueous well includes a test tree 18, a slip joint 20, valve 22, pressure recorder 24, sampler 25, pressure recorder 26 and packer 27. The packer is set with the slip joint partly contracted and the tree 18 supported by rams of a blow-out preventer in the wellhead 7. A hydraulic jar may be incorporated in the string above the packer, a safety joint being placed between the packer and jar. The packer may be separate from the string and be connected to it by a stinger. Initially the parts of the samples are as shown in Fig. 2a to prevent formation fluid flowing through the sampler, the pressure of mud in the annulus adjacent holes 48 being insufficient to move the piston 42 against nitrogen at pressure in the chamber 44 above the piston. On increasing pressure of the mud the piston rises and inlets 37 and outlets 41 are opened so that formation fluid flows through the sample chamber 45, the piston travel being limited by a stop held by a shear pin and the piston speed being restricted. The formation fluid sample is trapped in chamber 45 by further increasing the mud pressure to raise the piston to close the inlets and outlets the piston being held in the further raised position by a latch. Alternatively the sample may be trapped by reducing the mud pressure and allowing the piston to sink.

The flexible corner portions may be joined to the adjacent wall panels so as to allow a degree of movement between the joined parts. The walls of the tray may be perpendicular to the base, or sloped inwardly or outwardly, dependent upon the shape of the articles. Each wall may slope outwardly over its lower portion and inwardly over its upper portion. Handles may be provided on one or more wall panels.

Abstract: 1,012,118. Read-only stores. INTERNATIONAL BUSINESS MACHINES CORPORATION. Oct. 16, 1964, No. 42239/64. Drawings to Specification. Heading G4A. In a digital data store, each drive line is divided into two parallel paths at each storage location and one only of these paths is effectively inductively coupled to a sense line which crosses the drive line at the storage location, a bit being stored by introducing an impedance discontinuity in one of the two paths. The inductive coupling between drive path and sense line is achieved by having the conductors cross each other at an acute angle (which may be zero). The drive and sense lines are printed on respective dielectric sheets laid on top of one another (Fig. 5, not shown). As a modification (Fig. 6, not shown) drive lines printed on a first sheet are surrounded by a further sheet on which sense lines are printed. The impedance discontinuities may be introduced by punching holes in a metal ground-plane positioned beneath the pair of dielectric sheets. Alternatively, this may be done by selective deposition of a thin film of magnetic material between the ground-plane and the lines. In order to reduce impedance variations of a sense line where it crosses a drive line, dielectric blocks 13 (Fig. 6, not shown) may be inserted between it and the ground-plane of the next storage plane above. The sense lines may vary in length to compensate for the drive signal delay in passing along a drive line.
