Patent GB-2214987-A (GB)
Title: Gear pump
Inventor: TUBB NEVIL
IPC: F04C14/04
Filed: 1988-02-05
Abstract: The pump pumps from left to right for clockwise shaft 1 rotation in the configuration shown. If the relative rotor position is changed, by turning eccentric mounting ring 10 through 180 DEG C, the relative internal rotor/pinion geometry would change, so as to pump R to L for the same clockwise rotation. If alternatively the rotor sense of rotation is changed, then, although the pumped direction initially also changes from R to L, ball 20 or a roller, instead of rattling loose in its crescent-shaped cavity 19, will bind and entrain ring 10 with rotor 5, causing it to rotate. After 180 DEG C, the ball meets end 21b of a strip of steel fixed beneath a cover plate and is dislodged so that ring 10 stops rotating. The geometric change thus engendered gives L to R pumping once more. The same applies in the reverse sense, using end 21a. Thus, whichever way the shaft rotates L to R pumping is automatically achieved, e.g. for safety as an oil pump for a compressor. <IMAGE>

Title: Cleaning and lining pipe
Inventor: O'CONNELL MICHAEL JOSEPH
IPC: B29C63/48
Filed: 1990-06-08
Abstract: A process for lining a metal pipe (10) involves initially cleaning the internal surface of the pipe using a honing device (15) having three abrasive blocks (18) mounted on radially extending arms (17) at 120 DEG C separation. The debris is removed using a wire brush (25 Fig 2a) and then a liner (30) is pulled through the pipe (10), the liner (30) being interference fitted within the pipe (Fig 2c). An excess length of liner (30) is left at each end of the pipe (10) for formation of a flare at each end. The flare is formed in two stages using a heated pre-flaring die (46) and a heated final-flaring die (47, Fig 3d). The action of deforming the liner (30) using the dies is carried out slowly with intermediate pauses in the pressing action to avoid stress cracking. At the end of the pressing action of each die, both the liner (30) and the die are cooled using liquid coolant to avoid relaxation of the deformation of the liner (30). <IMAGE>

Title: Single-crystal diamond of very high thermal conductivity
Inventor: ANTHONY THOMAS RICHARD
IPC: C01B31/06

Abstract: Single-crystal diamond consisting of isotopically pure carbon-12 or carbon-13 has been found to have a thermal conductivity higher than that of any substance previously known, typically at least 40% higher than that of naturally occurring IIA diamond. It may be prepared by a method comprising comminution of diamond of high isotopic purity, such as that obtained by low pressure chemical vapor deposition employing an isotopically pure hydrocarbon in combination with hydrogen, followed by conversion of the comminuted diamond to single-crystal diamond by diffusion under high pressure through a metallic catalyst-solvent material to a region containing a diamond seed crystal.
Patent GB-905571-A (GB)
Abstract: 905,571. Moving coil instruments. SANGAMO WESTON Ltd. April 18, 1961 [April 19, 1960], No. 13983/61. Class 37. In a method of cementing a pivot base 12 to a movable coil 11 for an electrical instrument, the pivot base and cement are heated by passing an electric current through the pivot base. Cement is applied between the coil and insulating layer 17, Fig. 1, and again between 17 and part 14 of the pivot base. The coil is then mounted on a jig 20 (Figs. 2 and 3) the coil being positioned by pedestal 22 and the pivot bases by plungers 26. The supports 41, 42 which retain the plungers in position are insulated from one another and the plungers, and carry spring members 44, 46 which abut on opposite sides of the pivot base. These members are connected to the current source 56 via transformer 52, and the heat generated by the passage of current through the contact between springs and pivot base very rapidly cures or partially cures the cement, which may be of either the thermoplastic or thermosetting type. The coil assembly may then be removed from the jig and finally cured by oven baking, if necessary.

Title: Filter cleaning system
Inventor: MUGICA FERNANDO MARTINEZ
IPC: B01D21/00
Filed: 1991-01-25
Abstract: Electro-erosion liquid 24 is filtered as it flows from inlet 11 to outlet 12 of filter 10. Periodically valve 6 is adjusted to reverse the flow through the filter, the backwash liquid flowing via conduit 42 to settling tank 9. Then forward flow is restored to rinse the filter, the liquid still flowing from the filter to tank 9. Finally normal filtration is restored, but the first filtered liquid is recycled through conduit 13' to dirty liquid tank 7 before flow is diverted to normal outlet 13. Tank 9 is divided by adjustable wall 40 with lower apertures 41. During backwashing the flow carries solids through the apertures to settle in chamber 92. Chamber 91 collects relatively clean rinsing liquid which is recycled via valve m, to tank 7. Level sensors O1 to O3 in chamber 91 control the various steps in the cycle. <IMAGE>

Title: Improvements in or relating to a bendable sleeved roll
Inventor: GINZBURG VLADIMIR B
IPC: D21G1/02
Filed: 1991-04-04
Abstract: A sleeved roll 202 generally has a bendable arbor 206. The sleeve 208 is shrunk-fit on the arbor such that the dimensional difference between the arbor diameter and the sleeve inner diameter varies along the arbor axis. Thus the radial stresses induced by the shrink-fit vary along the axis of the arbor. The sleeved bendable roll may be employed as a workroll or as a back-up roll 82 in a rolling mill which may include means (162-176, Fig 8) for controlling roll gap and means (186) for sensing the eccentricity of the back up rolls. The roll is assembled by providing a bendable arbor, having an axial surface, and a hollow sleeve, preferably vertically oriented, at least a portion of the arbor surface or the sleeve inner surface being contoured longitudinally, e.g. convexly, positioning the hollow sleeve with its inner surface adjacent the arbor, and then shrink-fitting the sleeve inner surface on the arbor at the convexly contoured zone. In alternative embodiments, before shrink fitting, the sleeve surface is cylindrical and the arbor longitudinally convex, (Figs 4, 5 & 8), the sleeve surface is concave longitudinally and the arbor convex (Fig 10) and the sleeve surface is convex longitudinally and the arbor cylindrical (Fig 12). <IMAGE>
