Title: Earth formation testing by regression analysis of induced flow pressure measurements using refined model assuming hemispherical induced flow.
Inventor: STEWART GEORGE
IPC: E21B49/00
Filed: 2009-01-08
Abstract: An earth formation testing system for determining one or more formation parameters comprises a wellbore formation testing tool including straddle packers 107a,107b for isolating a part of the formation, a pump 108 for inducing a fluid flow in the formation and one or more pressure measurement probes 110. A computer 111 is provided which receives and records pressure data and performs a regression analysis using a refined analytical model and the recorded data to determine properties of the earth formation. The refined analytical model is derived using a correction factor determined by assuming the induced flow is hemispherical, preferably by using finite element modelling.

Filed: 1933-04-06
Abstract: 414,469. Turning. SWIFT & SONS, Ltd., G., and SWIFT, W., Claremont Ironworks, Halifax, Yorkshire. April 6, 1933, No. 10278. [Class 83 (iii).] A lathe with sliding, surfacing, and screwcutting motions has a hand lever pivotally movable in two planes at right angles to control any one of the three motions in such a manner that no two of such motions can be engaged simultaneously. The control lever d carried by the lathe apron is moved to the right and upwards, Fig. 6, from the neutral position e<1> to the position e<3> for longitudinal feed, this slides a fork d' to the left, Fig. 4, and with it a wheel block g, g<1> to complete the gear train h<2>, h, g, g<1>, g<2>, a, the last wheel engages a rack on the bed to give the feed. The worm wheel h<2> is driven from a drop-worm h<3>, Fig. 1, pivoted at h<5> and rotated from the usual longitudinal feed shaft. Upward movement of the control lever a lifts the worm h<3> through gear segments i, il and abutments i<3>, h<6>, a spring-pressed latch holding the worm in the engaged position until the control lever is depressed. Movement of the control lever into the position e<2> moves the wheel g into engagement with a wheel b for the surfacing movement the worm-box being again raised to complete the drive. Downward movement of the control lever to position e<4> rotates the shaft d<3>, to which the block d<5> is keyed, and through rotation of the disc i which has cam-slots to engage projections s, Fig. 5, on a split nut t, the nuthalves are closed together on to the lead-screw c for the screw-cutting motion, the drop-worm remaining disengaged during this operation. The worm in the drop-worm box may be arranged to slide axially against spring-pressure out of engagement with the worm-wheel when movement of the saddle is arrested either accidentally or by a stop, this movement of the worm being used to trip the worm-box and thus effect complete disengagement.

Abstract: 804,388. Electrically released switches. SIEMENS-SCHUCKERTWERKE A.G. April 4, 1956 [April 6, 1955], No. 10310/56. Class 38 (5). A switch has fixed and movable contacts 1, 2, 13, a first spring 20 for biasing the movable contact 13 to the closed position, electrodynamic means 17, 18 which, when actuated under the effect of a circuit-breaking impulse, is arranged both to act on the movable contact to displace it to the open position and also to release a second spring 24 which biases the movable contact into its open position and retains it there. In the arrangement shown, the discharge of a condenser (not shown) into a fixed winding 18 induces current into a conductive ring 17 which is repelled and moves an insulating member 15 upwards to open the contacts. In its upward movement the conical base 16 of the member 15 releases latches 26, 27 which retain the spring 24 compressed, so that the strong spring 24 overpowers the weaker tension spring 20 to ensure the effective opening of the contacts. The opening movement of the member 15 and contact 13 is arrested by a rubber buffer 29 housed within a cap 28. A high-power fuse 9 may be connected across the contacts.

Title: Improvements in or relating to devices for feeding tapes
IPC: G03D3/14
Filed: 1949-04-19
Abstract: 699,903. Photographic developing apparatus. PHILIPS ELECTRICAL, Ltd. April 19, 1949 [April 20, 1948], No. 10347/49. Class 98 (ii). [Also in Group XVI] Relates to a device for feeding tapes, especially thin films of regenerated cellulose through a developing apparatus, which device comprises upper and lower rollers 3 and 4 freely mounted on shafts 5 and 6 arranged in two superposed rows, such that the tape 1 passes alternately around a roller in each row. Each shaft 5 is driven faster than its roller 3 and a spring 7 exerts a constant, but adjustable, braking pressure on the roller 3. For values of tape tension slightly greater than that when the driving force exerted by a roller 3 on the tape equals the braking force exerted by a lower roller on the tape, the increase in driving force exerted by an increase in tape tension in the tape portion between two successive upper and lower rollers exceeds the increase in braking force exerted by the lower roller, provided that for a particular pressure of the spring 7 a suitable choice is made of (a) the ratios of the outer diameters of the upper and lower rollers and their shafts, (b) the value of the frictional coefficient between the rollers and shafts and (c) the weights of the rollers. Adjustment of the spring pressure permits, for example, a film to be subject to varying tensions during its treatment, for example, in order to compensate for contraction of the film due to a film drying operation. French Specification 940,639 is referred to.

The catalyst may be nickel, chromium, molybdenum, tungsten, iron, cobalt, ruthenium, platinum or palladium or any mixture thereof supported on silica, alumina or calcium carbonate or any mixture thereof.
