Title: Method and means for inserting fluid-impervious tubing into a conduit
IPC: H02G1/08
Filed: 1959-11-19
Abstract: 937,930. Borehole linings. W. I. TATTLE. Nov. 15, 1960 [Nov. 19, 1959], No. 39255/59. Class 85. [Also in Group XXVIII] In a method of inserting fluid-impervious tubing 5 into a conduit 1 and laying the tubing therein along a desired length thereof, the flexible, fluid-impervious tube 5 is prepacked into compressed form, the leading end 13 sealed, the trailing end 22 is anchored, and a fluid medium is transmitted into the trailing end so that the tube becomes inflated and unpacks as it travels through the conduit. As shown, the tube 5 is pre-packed by a process of annular accordion-pleating 18 in a projectile 9 having a nose 14. The leading end of the tube is tied at 16 to a grommetted lug 15A across the interior of the nose 14, and the trailing end 22 is clamped by an element 6 the central aperture 23 of which is connected to a blower. When the projectile emerges from the exit of the conduit the leading end is cut open, when the tube may remain in the conduit to provide a lining or may be converted into twine-like form to pull through the conduit a follower string, which eventually is used to pull an electric cable therethrough. The tube is converted to a twinelike form by anchoring the leading end in open position to permit the escape of air while the opposite end of the tube is attached to a rotary drill. A flow meter may be connected between the blower and aperture 23 whereby knowing the volume per foot which the tube holds, the location of any blockage in the conduit, by which the projectile is obstructed, may be calculated.

Abstract: 1,016,564. Disc brakes. AUTOMOTIVE PRODUCTS CO. Ltd. Nov. 1, 1963 [Nov. 1, 1962], No. 41436/62. Headings F2E and F2F. An automatic adjuster for a disc brake is incorporated in an hydraulic applying cylinder 1 and comprises a pair of telescoping members 8, 9 in screw-threaded engagement, interposed between a sliding plunger 3 of a hand brake mechanism (not shown) and the rear face of a hollow piston 2, and pawl-and-ratchet mechanism for adjusting the members 8, 9 on operation of the hand brake mechanism in the brakeapplying direction, the mechanism including resilient means whereby relative movement of the pawl and ratchet members of the mechanism occurs only when a predetermined applying movement is exceeded, and whereby further applying movement does not cause further operation of the mechanism. In one embodiment, Figs. 2 and 3, the resilient means is a torque spring 13 wound on an anchor-pin 14, one end 12 of spring 13 forming a pawl to co-operate with a ratchet wheel 11 on the tubular member 8 which abuts a flange 7 of the plunger 3. The member 9 is telescopically received in the member 8 and secured to a plate 10 mounted within the piston. A lever 18 is pivoted at 19 and engages by an abutment 20 the opposite end 17 of the torque spring, and by an abutment 21 the end formed as a pawl. In operation, movement of the plunger in the brake-applying direction causes flange 7 to abut the lever 18 which pivots to cause corresponding movement of the torque spring. The end 12 of the torque spring at first remains stationary owing to flowing, the ratchet wheel being held by a retaining pawl 23. When the resistance of the latter is overcome the ratchet wheel is moved to effect adjustment until the retaining pawl again arrests it and further movement in the brake application direction again merely flexes the pawl. In a second embodiment, Figs. 4 and 5, the pawl is formed by a lever 25 but the latter is pivoted on one limb 26 of a resilient U-shaped member 27 which is anchored non-rotatably by its other limb 29 to a bracket 32. Movement of the ratchet wheel is resisted by a resilient friction pawl 35, so that when the lever pivots consequent upon operation of the plunger 3 the member 27 fluxes and prevents movement of the pawl until a given movement has been exceeded, and also prevents further movement of the pawl after an adjustment, as in the previous embodiment.

A fluid-pressure servomotor comprises a diaphragm 3 1 , connected by a rod 78 to an operating member 54 of the device to be controlled, such as a valve. The diaphragm 31 forms one wall of a working chamber 75 to which fluid, such as nitrogen, is fed or exhausted under the control of an electrically operated valve 79. The supply of fluid to the working chamber 75 comes from a high pressure chamber 76 which is maintained under constant pressure by an electrically operated compressor 21 which delivery fluid from a low pressure chamber 20b to the chamber 76, the compressor being switched on and off by a switch 66 responsive to the pressure in chamber 76. As shown, the fluid flows from chamber 76 to the working chamber 75 through passage 85, valve 65 passage 83 and control valve 79, while flow from the working chamber takes place through valve 79 and passage 84 to low pressure chamber 20b. An intermediate chamber 74 may be provided to supplement the flow from chamber 76 to chamber 75. One wall of chamber 74 is formed by the diaphragm 3 1  and another by a diaphragm 57 of smaller area. As the diaphragm 31 moves downwards the volume of chamber 74 reduces and fluid is forced through passage 86 and a two way valve 88 to the feed passage 82. When the diaphragm 3 1  moves upwards fluid flows from chamber 76, valve 65 and passage 83 through the valve 88 to the chamber 74 which is maintained at a pressure below that in chamber 76, The control valve 79 is loaded by a spring 81 such that the loading is varied by movement of the diaphragm 3 1  until the control valve is recentred. All the chambers are arranged in a fluid tight housing. In a modification, the loading of the control valve is replaced by a loading on the diaphragm.
