Title: One-way pig means

Abstract: 1460216 Pipeline pig; detecting and repairing leaks in pipes EXXON PRODUCTION RESEARCH CO 31 Oct 1974 [5 Nov 1973] 47156/74 Headings F2P and F2N A pig of the type adapted for one way pipeline travel has a body 52 slidably supporting at least one sealing cup 26, 27 each having a forwardly extending lip portion, and is further characterized by the inclusion of anchor means 56, 57 positioned on the body member and movable therewith, whereby the anchor means, upon application of a pressure differential in the opposite direction to travel urges the sealing cup lips into contact with the pipe wall effecting anchorage of the pig relative to the pipeline. As shown anchor means comprising flanged discs 56, 57 are fixedly attached to the body 52 forming a unit which is slidable according to the direction of the applied pressure differential between the position shown, in which the pig is adapted for propulsion, and an anchorage position wherein rims 56B, 57B of the flanged disc member engage tapered lips 32, 33 of the sealing cups 26, 27 to effect anchorage via the resulting wedging action against the pipeline wall. Sealing cups 26, 27 are formed of a resilient material, e.g. natural or synthetic rubber, polyurethane and are supported by, and attached to, rigid (e.g. metal) discs 28, 29, to form support means wherein openings 59, 60 are formed to provide fluid bypass. The pig has use in marine pipe recovery, and has further application in detecting leaks in such piping. In the latter case the pig is progressively propelled by forward pressure application to points along the pipeline at each of which anchoring by reverse pressure application allows testing of the pipe section so defined for ability to sustain the applied pressure; which procedure is repeated at further points along the pipeline until pressure fall off, i.e. a leak, is detected.

Abstract: 1,139,007. Testing electrical insulation acoustically. GENERAL ELECTRIC CO. 24 Oct., 1966 [21 Dec., 1965], No. 47596/66. Heading H4D. In an arrangement for detecting and locating insulation faults in fluid-filled encased electrical apparatus supplied with an A.C. test voltage by triggering the time base of a cathoderay tube oscilloscope by a signal produced simultaneously with the occurrence, at a selected point in each cycle of the test voltage, of a corona or spark discharge within the apparatus and deflecting the trace in a direction at right-angles to the time base by the electrical output of a sonic transducer positioned at a selected point on the apparatus casing so that, due to the finite transmission time for acoustic signals from the source of the corona or spark discharge to the transducer, the distance between the latter deflection and the commencement of the time base is a measure of the distance of the fault from the transducer, obscuration of the point of this deflection by random sonic components from echoes, from corona bursts occurring at other points in the test voltage cycle and from signal persistence and transducer ringing is prevented by converting the received sonic signals to a series of digital signals representative of the polarity and magnitude of instantaneous values and then averaging such digital signals over a plurality of successive test periods so that the signals corresponding to the selected point in the test voltage cycle are enhanced whilst the undesired random signals approach zero. The location of the corona or spark discharge is then determined by triangulation by placing the sonic transducer at two other positions or by employing three spaced transducers. As shown in Fig. 1, the time base trigger voltage is derived via a capacitance tab 8 coupled to the test voltage supply conductor 4 such voltage, which may be recorded by means 28, being fed to a selection circuit 40 providing an output voltage set between predetermined limits, i.e. it occurs at a predetermined point in the A.C. test voltage cycle. The sonic disturbances are detected by a transducer 10, recorded if desired by means 28, and fed together with the predetermined trigger voltage to a device 30 which performs the digital conversion and averaging referred to above so that in the trace on oscilloscope 48 the commencement of the deflection due to the desired sonic disturbance is clearly discernable. When recorder 28 is employed the accuracy of the system may be improved by repeated re-runs of a succession of recorded test periods. The operation of the device 30 is described.

Title: Device for dispensing web material

Abstract: 1528266 Web dispenser M GRANGER 16 Nov 1976 [19 Nov 1975 11 Feb 1976] 47778/76 Heading B8M A device for dispensing web material comprises a rotatable roll R of web material mounted in a support A and biased by springs 11 to engage a drum 17 also mounted rotatably in the support A so that the drum 17 rotates when the web material is pulled, the drum 17 being mounted on a shaft 18 which is non-rotatably secured to a lever 26 which is connected to one end of a spring 21 the other end of which is secured to a structure C mounting the drum 17 inside the support A, a cutter 25 located inside the drum 17 and operated by a camming arrangement, the arrangement being such that when the web is pulled the drum 17 rotates thereby stressing the spring 21 which stores energy until a point is reached when the spring 21 releases its stored energy to vigorously rotate the drum 17 in the same direction, and simultaneously the camming arrangement causes the blade 25 to project through a longitudinal slot 17b in the drum 17 to cut the web material instantaneously and after the cutting operation to retract into the drum 17. When the spring 21 releases its energy and rotates the lever 26 to rotate the drum 17 a cam 19a co-operates with a roller 22 of the cutter assembly to displace the cutter 25 exteriorly of the drum 17. During this drum movement a pawl 28 mounted on the drum shaft 18 brushes past an abutment 30 provided on a flange 5b of the carrier C. After the cut, the drum 17 rotates due to its own inertia until the pawl 28 engages a shock absorber 29, mounted on the shaft 18, which brakes the drum. A spring 31 which is compressed to provide the brakes then relaxes to rotate the shock absorber 29 and to rock the pawl 28 in the reverse direction only to engage it with the abutment 30. The support A is made of sheet material and its hood 4 is made of sheet metal or plastics. The cutter 25 is either embedded in its carrier 24 or moulded integrally.  In another embodiment (Figs. 11-17) the cam arrangement is constituted by a roller 51 provided on an arm of the blade 49. The blade 49 is pivotally mounted at a point 49f to an end plate 46c of the drum. The roller 51 rides in a cam groove 5e provided in a flange 5b of the carrier C. When the roller 51 assumes the peak portion (c-d) of the cam groove 5e the blade is projected to cut the web and when it enters portion d-a the blade is retracted. The blade begins its exit after one quarter of the revolution of the drum from its rest position and remains projected for one fifth of the drum revolution. In another embodiment two drum units are mounted together to be used alternately or simultaneously, Figs. 18-20 (not shown).

The NO 2  group in said methyl ester is reduced followed by hydrolysis to form a compound I (X=NH 2 , R=H). A free acid is converted to an appropriate ester. The optical isomers of 2-(2-fluoro-2<SP>1</SP>- nitro - 4 - biphenyl) - propionic acid are prepared by forming salts with d-(+)- or l-(-)- α-methyl benzylamine. Compounds I have anti-inflammatory and anti-thrombotic effects and form with a carrier a pharmaceutical composition which may be administered orally, parenterally, rectally or topically.

A transmission or delay line is correctly terminated at one end by an impedance which comprises the emitter circuit of a normally conductive semi-conductor device arranged so that substantially all of the line current flows through the emitter circuit. Pulses to be displayed on a cathode-ray tube are amplified by transistor 28 and passed through an artificial or real delay line 10 to a further amplifier stage 22 coupled to the cathode-ray tube deflection circuit. The input end of the line is also connected to a transistor amplifier 16 from the output terminal 20 of which undelayed pulses are obtained for triggering the time base circuit. To prevent reflections along the line, resistors 12 and 14 are added to increase the impedances of the transistors so that the line is correctly matched at both ends. The amplifier stage 22 could alternatively be of common emitter type in which case the impedance 14 could be omitted if the input impedance of the transistor were equal to the line impedance. Complex networks may replace resistors 12 and 14 and circuit 32, 34 compensates for the distributed capacitance of the line.
