Abstract: A leak detector and locator utilizes an electrical cable disposed in proximity to fluid carrying pipes or other area wherein a leak may occur. Pulses are applied to the cable and the reflected wave form is analyzed to detect changes in the characteristic impedance of the cable caused by fluid penetrating the insulation of the cable. A different portion of the waveform corresponding to a different point on the cable is sampled after each pulse is generated and stored until the entire waveform has been sampled and stored. Subsequent samples of the waveform are compared with the stored waveform and a leak is indicated if the subsequently sampled waveform differs from the stored waveform by a predetermined amount.

Abstract: 958,941. Spindle driving, stop motion. J. E. MAKANT, and H. COLLINS. Jan. 10,1961, No. 1003/61. Heading D1D. A mechanism for stopping a yarn twisting spindle upon breakage of the yarn passing to the bobbin on that spindle comprises a clutch provided between the spindle and a driven whorl such that upon yarn breakage compressed air operated means simultaneously releases said clutch and actuates a spindle brake. In the ring twisting arrangment shown a spindle 14 (see Fig. 4), removeably located by bearings 18,19, is driven from a whorl 44 through a clutch which comprises the upper surface of the whorl 44 and a downwardly urged member 46, 48 slideably keyed in the spindle blade. A brake plate 40 surrounding the top of the whorl 44 is mounted on pistons 34, located in upstanding cylinders 22, 22<SP>1</SP> to which compressed air may be pumped so as to raise plate 40 to lift the clutch member 46, 48 and so interrupt the drive to the spindle and brake the spindle. A cap 57 having sprung arms 63, 63<SP>1</SP> is provided on the spindle for holding it down. As shown in Fig. 1 each yarn to be twisted passes from a package C, through a drop wire 73, between rollers 66, 67 and 68 and through a further yarn sensing guide to pass to the traveller on the ring D Upon yarn breakage either between a package C and roller 66 or between roller 68 and the traveller, , a suitable mechanical linkage causes the operation of a plunger 84 of an air valve V so that compressed air is supplied, via a conduit 94, to the cylinders 22, 22<SP>1</SP> to lift the pistons 34 and plate 40 and thus interrupt the spindle drive and brake the spindle. In an alternative form the air valve is operated through an electrical linkage.

Title: Well Completion Apparatus and Method
IPC: E21B33/129
Filed: 1967-01-09
Abstract: 1,150,671. Wells &c. GRAY TOOL CO. 9 Jan., 1967 [18 Feb., 1966], No. 1188/67. Heading E1F. A tubular part used in completing a well carries a contracted split support ring which is permitted to expand into engagement with a supporting member. The tubular part is a Hanger 30 which is interposed in a casing string 28. The string is lowered into the supporting member which is a casing 10 so that a pawl 98 is carried below a trip groove 14 in the casing. The string is raised so that the pawl extends into the trip groove and further upward movement of the string removes pins 78 connected to the pawl from sockets 82 in the ends of support ring 50 which then tends to expand. Continued upward movement of the string cause a cover plate 102 to cam the pawl inwardly so that the string may be raised to carry the support ring above a latching groove 12 in the casing. If the string is lowered the support ring snaps into the latching groove and further lowering of the string causes the hanger to expand the support ring further into the latching groove until the weight on the hanger is transferred to the support ring which in turn transfers the weight to the casing. The trip and latching grooves may be formed in the bore of a hanger engaging the conductor pipe of a sub-aqueous well completed above the water level, and a hanger having a support ring engaging the latching groove may have its bore formed with latching and trip grooves for a further hanger. The casing strings above the hangers may have screw joints which permit removal of the well completion above the mud line so that the well may be capped and its position indicated by a buoy. A casing string may be supported by a series of hangers according to the invention and spaced along the length of the string.

Filed: 1922-01-17
Abstract: 200,535. Gardner, J. Jan. 17, 1922. Screw motors ; regulating.-A wind motor of the type having a wind wheel on the leeward side of a vertical post is regulated by means of a single controlling vane on the wheel frame which automatically varies the area it presents to the wind and thereby causes the wind wheel to move into or out of the wind according to the strength of the wind. A frame 1, mounted to turn on a vertical post 2, carries a wind-wheel shaft 3 and a horizontal governor-vane shaft 10 at right angles thereto. A dynamo 6 driven by the wind-wheel shaft is mounted on the windward side of the frame 1 and roughly balances the wind-wheel. The governor-vane 9 is arranged with a small initial inclination to the horizontal. Centrifugal governor-weights 18 control the movement of a sleeve 16, on the wind-wheel shaft 3, which by linkage comnecting the governor-vane shaft 10 causes the governor-vane 9, as the speed cf the wind-wheel increases, to present a larger area to the wind and so turn the wind-wheel to a corresponding extent out of the wind. A fusee device 21 giving an increasing torque at increased inclination tends to restore the governor-vane 9 to its initial inclination. A cord attached to an arm 24 on the governor-vane shaft 10 enables the wheel to be stopped by turning the governor-vane 9 into the vertical position; the arm 24 may further apply a brake to the wind-wheel shaft 3. The vane carrying arm 4 of the wind-wheel is secured to the shaft 3 by means of a key-plate 25 fitting slots in the shaft 3 and the arm 4; bolts 26 pass through the arm 4 and the key-plate 25 and the latter is retained on the shaft 3 by a nut 28. Specification 1175/09 is referred to.
