Title: Behind casing water flow detection
IPC: E21B47/10
Filed: 1976-09-15
Abstract: 1505446 Measuring flow-rate of water in borehole casing TEXACO DEVELOPMENT CORP 15 Sept 1976 [3 Nov 1975(3)] 38143/76 Heading G1A The volume flow-rate of undesired water flow behind the casing 102 of a borehole e.g. along a cement lining channel 110, is measured by the use of neutron activation analysis apparatus comprising a fast neutron source 126 and longitudinally spaced detectors D 1 , D 2 , the source causing activation of oxygen nuclei to form unstable nitrogen N<SP>16</SP>, the gamma radiation decay from which is detected. The Specification provides an expression relating the ratio of the counts from the two detectors with the linear velocity v of the water flow. Using v, the volume flow V may be calculated from a further expression relating V to (among other known quantities) the count rate for a particular detector, the velocity v, the spacing S between the source and the particular detector, and the distance R from the particular detector to the centre of the water flow if R can be provided estimation or measurement. The value of R may be measured by two methods. In the first, pulse height analysis techniques are used to compare the counts in two gamma energy ranges, the ratio obtained being correlated with a calibration curve, Figs. 5 and 6 (not shown). In the second a specialized detector construction is used, Fig. 7. A central scintillator crystal 71 and an outer cylindrical crystal 72 (NaI or CsI-thallium activated) are respectively coupled to photo-multipliers and the ratio of the counts correlated with a calibration curve to find R, Fig. 8 (not shown). The activation analysis tool may be operated with a continuous source or preferably using a pulsed source. Different counting windows are used in each case, Figs. 4 and 5 (not shown). Typically, a Deuterium-tritium type accelerator is used to produce 14 MeV neutrons in bursts of 1 ms. The detectors are gated off for the initial period so that prompt gammas are not detected, then gated on for 6 ms. before the next accelerator pulse Fig. 11 (not shown). Synchronization pulses aid data handling as does the use of opposite polarity pulses from the individual detectors. A computer evaluates the value V at different heights sensed at 112. Measurements are taken with the logging tool fixed or slow moving. The tool is constructed in module form so that the source may be attached below the detectors for measurements in upward flowing water and vice versa, Figs. 9A-9C (not shown).

Abstract: 849,503. Treating polytetrafluoroethylene tubing. RESISTOFLEX CORPORATION. Dec. 10, 1957 [Dec. 28, 1956], No. 38419/57. Class 87(2). Elongated tubes of a resin such as polytetrafluoroethylene which is subject to radial deformation during sintering or quenching while supported within a pipe are produced by inserting a removable light weight core member before sintering or before quenching into the tube to prevent the deformation, the size of the core being such that it is readily removable from the tube after the heat treatment. In Fig. 3, an extruded length of tubing 30 is supported in pipe 10 and has a light weight core member inserted in it in the form of a coil 32 of steel wire having a generally circular outline as viewed from one end and which may take the form of a helix having approximately 2 turns inch. For best results, the diameter of the core member should be approximately 9/10ths the internal diameter of the tubing 30 prior to sintering. The core may be used for reducing " draw-down " (i.e. reduction in diameter of an intermediate section of the tube) during sintering, preventing collapse during quenching, or for both purposes.

Abstract: 1,068,253. Spark-erosion. AGEMA A.GÀ Sept. 9, 1965 [Sept. 18, 1964], No. 38499/65. Heading B3V. [Also in Divisions G1, G3 and H2] In spark-erosion apparatus the movement of the tool electrode 11 is controlled in dependence upon gap-voltage variations as measured by a voltmeter 41 (Fig. 3, not shown) associated with a light source and photo-electric cells 49, 50. When the gap voltage is below a lower limit, a shutter in the voltmeter obscures the photocell 49 so that an output signal is produced on a voltage divider constituted by resistors 52, 53 and the photo-cells 49, 50. This output signal is applied over an amplifier 54 to a transistor switch circuit 26 (Fig. 2, not shown) which is rendered conductive whereby the field winding 21 of a D.C. motor 16, geared to the electrode 11, is energized from a source 23 by way of a transformer 22 and rectifier 24 so that the electrode 11 is moved away from the workpiece 10 to increase the gap voltage. Similarly, if the gap voltage is above an upper limit, photo-cell 50 is obscured the output signal from voltage divider 49, 52, 53, 50 then being such that transistor switch 27 is rendered conductive whereby field winding 21 is energized over transformer 22 and rectifier 25 so that the tool electrode 11 is moved towards the workpiece 10. The upper and lower limits may be set by adjustment of the voltmeter 41 (see Division G1)

Title: Isomerization process and preparation of feed stream therefor
IPC: C10G61/06
Filed: 1957-12-17
Abstract: In a combination hydrocarbon separation and isomerization process a light naphtha boiling within the range 60-180 DEG F. containing aromatic and normal paraffinic hydrocarbons is passed through a contacting zone containing an adsorbent which selectively adsorbs aromatic hydrocarbons, at least a portion of the aromatic free naphtha is subjected to isomerization to form high octane isoparaffins and at least a portion of such isoparaffins is used to desorb aromatic hydrocarbons from the adsorbent to give a stream of a mixture of isoparaffinic and aromatic hydrocarbons.  The naphtha feed is preferably depentonised.  The adsorbent used may be a suitable char but is preferably a molecular sieve having 6-15   pore openings. The feed is preferably vaporized and conditions of 180-400 DEG  F. and 0-100 p.s.i.g. are used with flow rates of 0.05-5 vol./vol./hr. over fixed, moving or fluidized beds of adsorbent.  The raffinate may then be fractionated to remove naphthenes and highly branched isoparaffins, only straight chain paraffins or paraffins with single branches passing to the isomerization.  This is preferably a liquid phase process over a Friedel-Crafts catalyst such as aluminium chloride supported on "Porocel."  Olefines should not be present in amounts more than 0.2 per cent, but 0.2-0.5 volume per cent of benzene may be present and 5-20 volume per cent of naphthenes. Temperatures of 100-275 DEG  F., pressures of 100-450 p.s.i.g. and flow rates of 0.3-3 vol./vol./hr. are used. Hydrogen chloride may be present in the feed as an activator in amounts of 0.1-6.0 weight per cent and 0.1-3 mol. per cent of hydrogen may be added.  The isomerisate is then fed to the fractionator before the isomeriser to remove highly branched isoparaffins and recycle other materials. This fractionator may be placed after the isomeriser if the feed contains little isoparaffins and in another alternative is placed before the contacting zone.  The highly branched product is passed through the adsorbent in the vapour phase at 140-500 DEG  F. Extraneous desorbents may be used in conjunction with the isomerisate such as heavier paraffins and naphthenes or purge gases.

Abstract: 1479120 Aircraft warning indicators SUNDSTRAND DATA CONTROL Inc 26 Sept 1975 [1 Nov 1974] 39456/75 Heading B7W An aircraft ground proximity warning system for generating a warning signal when the aircraft is below a predetermined safe altitude comprises a function generator for generating a signal representative of minimum altitude over terrain as a function of the speed of the aircraft which signal is combined with a signal representing the actual altitude over the terrain whereby if the aircraft is below said minimum altitude a warning signal is generated. A circuit is provided to inhibit the warning signal when the aircraft overflys another aircraft. The system is designed to receive a Mach number speed signal as a 400 Hz A.C. signal from a Mk II air data computer 16 or as 0-12 D.C. voltage from a Mk. III air data computer 18, explanatory references for the two computers being given in the Specification. A voltage source 40 generates a 26 volt exitation signal fed on lines 42, 44 to points D and E on a circuit board 26 and thence to an isolation transformer 46 the output of which is transmitted through resistor 48, limited by a negative 15 volt D.C. voltage applied through a diode 52 over line 50 and through diode 54. This is combined with an output through resistor 56 from a buffer amplifier 28 to turn a transistor 38 on and off in synchronism with the input to transformer 46. The input to amplifier 28 is the 400 Hz signal generated by synchro 20 fed over lines 22, 24 and resistors 30, 32. The output from transistor 38, modified by resistors 58 and 60 is a D.C. signal on line 62 proportional to Mach number and this is used as input to the negative terminal of a bias amplifier 64, the positive terminal being grounded through a resistor 66. The output of amplifier 64 is transmitted through a diode 68 to a summing junction 72 and will increae in linear relationship with increase in Mach number, to be combined with a biasing signal on a line 76 which represents an altitude of 500 ft. The output from junction 72 is applied to the positive terminal of a comparator 78 which receives also a signal on line 80 from a radio altimeter h representing actual height and the output from comparator 78 is fed to an AND gate 82 to operate over line 86 a warning signal. An input over line 84 is taken from an undercarriage switch to deactivate gate 82 during a landing manoeuvre. When plugged in to the Mk. III computer 18 the input is fed over lines 22<SP>1</SP>, 24<SP>1</SP> and through transistors 100, 102 that modify the circuit to accept a D.C. instead of an A.C. input. A circuit 200 has an input signal h<SP>1</SP> which represents the rate of change in altitude with respect to time, obtained by differentiating the radio altimeter signal h and its output on line 218 is of a sufficiently high voltage to suppress any signal output from biasing amplifier 64 thereby inhibiting the warning system when the aircraft overflys another aircraft.
