IPC: F16C1/26
Filed: 1934-06-26
Abstract: 442,214. Bowden mechanism; flexible tubes ; cables. DAVIES, F. P., and BOWDEN (ENGINEERS), Ltd., Victoria Road, Willesden Junction, London. June 26, 1934, No. 18872. [Class 80 (iii)] [See also Groups XXV and XXVIII] The flexible guide tube 1, Fig. 9, for a Bowden cable is formed of helically-interwound coarsepitched wires which interlock both radially and circumferentially. The cable 19 comprises a similar tube 22 surrounding a core comprising helically - interwound coarse - pitched round - section wires 21 surrounding a central wire 20. Figs. 1, 5 and 9 show various forms of interlock, the circumferential interlocking being obtained by deformation of the parts after assembly. In Fig. 7, round or other wires 23 are interposed between wires 24 which are channelled on one side and ribbed on the other, circumferential interlock being again obtained by deformation after assembly. A number of layers of wires may be used. In this case, the wires of the various layers may be of different or opposite pitch, and the wires of some of the layers need not interlock. The outer layer of wires of the tube 1 may be enclosed in an open-coiled single wire or may be encircled by a series of spaced rings.

Title: Well pipe plug
IPC: E21B33/03
Filed: 1936-07-08
Abstract: 473,093. Plugging well pipes. HYDRILL CO. July 8, 1936, No. 18968. Convention date, May 23. [Class 85] A plug adapted to be moved down through a tubular drill pipe string comprises radially movable means maintained in constricted condition during downward movement and adapted to' engage the pipe to hold the plug against upward movement, and means actuated when the lower end of the plug moves out of the lower end of the pipe for radially expanding said means within the pipe. The plug comprises a sectional body 28 slidably supporting at its upper end a rod 33c, Figs. 4 and 5, with an enlargement 33b and head 33a carrying a rubber &c. packer 32 ; the rod 33c is initially pressed downwardly by a spring 50, the annularly split lower end of the packer being then confined in a tapered bore 48 on the body. Within the body is a sectional rod 56, superposed springs 63, 64, tending to force the rod upwardly ; the rod is initially held in its lower position by dogs 81, Fig. 7, pivoted to the body and engaging notches 79 in the rod, a sleeve 83 holding the dogs in this position. At this time, the lower end of the rod is received between spring fingers 76, Fig. 7 ; on the rod moving upwards, return thereof is prevented by inward movement of the fingers 76. When used for plugging broken drill pipe before removal, the plug is inserted through the swivel 99, Fig. 1, and a closed pipe 102 is threaded to the swivel; a cock 98 above the kelly 95 is then opened and fluid supplied through hose 100 to force the plug downwards. On contact with coupling 94, Fig. 2, the sleeve 83 is retained, the dogs 81 then engaging the inner wall of the drill pipe with the rod 56 still held. When the dogs pass out of the lower end of the drill pipe, they swing outwardly, freeing the rod 56 which is forced upwardly by springs 63, 64, overcoming the resistance of spring 50 and raising the rod 33c to free the lower end of the packer from the bore 48 ; simultaneously, a cam member 91, Fig. 5, on rod 56 forces out balls 88 which co-operate with an upper shoulder 26, Fig. 12, of a coupling 23 to limit downward movement of the plug. Upper pressure is then slowly reduced and the well pressure raises the plug until the balls 88 contact the lower end of the next upper coupling 23a, the packer 32 being then within the bore of'coupling 23a, and the well pressure expands the packer into fluid-tight engagement with said bore.

Abstract: 474,004. Making stems for electric incandescent lamps. BRITISH THOMSONHOUSTON CO., Ltd. July 9, 1936, No. 19065. Convention date, July 10, 1935. [Class 39 (ii)] In making stems for electric incandescent lamps and similar devices, such as electric discharge devices, a pair of leading-in conductors 13, Fig. 2, are assembled adjacent to the inner wall of a stem tube 10 and on opposite sides thereof, and heat is applied to produce a fused mass of glass closing off the tube and enclosing the leading-in conductors, whereupon the glass mass is clamped about the conductors and the portion 21 between the conductors is compressed to a greater extent than the remainder so as to force the glass thus compressed outward around the conductors. In the example, the lamp stem comprises an exhausting-tube 11 and an arbor 12 which, with the leading-in wires 13, are assembled within the stem tube 10 in an automatic stem machine and carried past a series of fires which fuse together the juxtaposed ends of the stem tube, exhaust tube, and arbor. The assembly is then carried to clamping-jaws which are provided on their inner faces with matrices 17, 18 formed with bosses 19, 20 on their faces. Both sides of the stem press 14 between the leading-in conductors 13 are thereby indented, producing the thin portion 21 and forcing the plastic glass to each side to provide more glass at the parts 30 around the welded joints between the parts 27, 28 of the leading-in conductors. Preferably also the matrix 17 is provided with a projection or lug 22 extending from the upper edge of the boss 19 and arranged to produce an indentation 23, Fig. 2, in line with the exhausting-tube 11. By forcing air into the exhausting-tube a blow-out is produced at the indentation 23 and an exhausting-aperture formed in the stem. In a modification, both matrices are formed with projections, similar to the matrix 17, Fig. 5, and the thin portion of the glass is punched out, so that when air is forced down the exhausting-tube a blow-out occurs at the bottom of the latter. Specification 226,215, [Class 39 (ii)], is referred to.

In a gas-blast operated interrupter the arc is transferred from the moving nozzle contact to a fixed nozzle electrode during an opening operation and the path of the gas blast is changed from outside to inside the nozzle electrode. A gas blast from a valve (Fig. 2, not shown) enters the chamber 39 and moves the contact 31 downward. Initially the gas passes between the movable contact 31 and arcing electrode 32 to exhaust through a passage 45 but as the contact 31 moves downward the passage 45 passes a projection on the electrode 32 and the gas passes down the inside of electrode 32 and exhausts through passages 44, 45. Passages 36 allow the pressure gas to pass to the upper side of a piston 42 which moves down against the bias of a spring 35 and reduces the force of spring 34 opposing contact movement. The blast valve may be mounted on a hollow insulator and supply two such interrupter units (Fig. 1, not shown). Fig. 3 (not shown) illustrates a " servo " system controlling the blast valve.
