Title: Well control apparatus
IPC: E21B33/127
Filed: 1975-04-16
Abstract: 1505194 Boring earth; wells &c. LYNES INC 16 April 1975 [18 Nov 1974] 15557/75 Heading E1F Apparatus for controlling wells during drilling operations includes a body 12 (Fig. 2) for connection in the drill string, the body having a bore 16, an inflatable packer 14 carried by the body 12 for sealing off the well bore annulus A, a bore close off tool 11 (Fig. 1) movable through the drill string to seat in the body 12 where it is secured by latches 131 and a control valve 35 which controls inflation and deflation of the packer 14 in response to the difference between the pressure in the well string above the seated bore close off tool 11 and the pressure in the well bore annulus A above the packer 14. As described the body 12 includes a sleeve valve 17 normally held in its upper position (Fig. 2) by spring 16b and control valve 35 normally held in its lower position by spring 36. When the bore close off tool 11 is seated on the valve 17 and latched to the body 12 by latches 131, chamber 50 of control valve 35 is connected to bore 16 and chamber 38 housing the valve 35 is connected to the well bore annulus above packer 14, the pressure internally and externally of the packer 14 being equalised so that the packer 14 remains deflated and normal drilling operations may proceed. When it is desired to inflate packer 14 the pressure in bore 16 is increased, thus shifting control valve 35 (Fig. 4) to connect the packer 14 to bore 16 to inflate the packer. A check valve 151 maintains the packer 14 in inflated condition. During inflation the pressure in the well bore annulus A above and below the packer 14 is equalised. A further increase in pressure in bore 16 shears pin 107 (Fig. 1 and removes plug 106 so that the bore 16 in the drill string can communicate with the well bore below the packer 14 through check valve 101. The bore 16 can be connected to the well bore annulus A above packer 14 by dropping a plug 160 (Fig. 7) down bore 16, the plug 160 shifting a spring loaded sleeve 257 to uncover ports 152. The plug 160 can be removed by fishing head 161. To deflate the packer 14 a ball (not shown) is dropped down the bore 16 and seats in valve sleeve 111 (Fig. 1) in the bore close off tool 11. An increase in pressure in the bore 16 then shears pin 118a and shifts the sleeve valve 111 to uncover port 120. Port 120 by-passes the check valve 151 so that the packer 14 may deflate upon decrease in pressure in bore 16. During deflation the pressure in well bore annulus A above and below packer 14 is equalised. The bore close off tool 11 may be removed by an overshot (not shown) which depresses spring loaded sleeve 126 on the tool 11 and engages shoulders 129 to lift the tool 11. A central plunger (not shown) on the overshot engages the latches 131 to retract them to permit removal of the tool 11. In a modification (not shown) the sleeve type control valve 35 is replaced by a spool type control valve.

Title: Improvements in electromagnetic sound recording and reproducing machines
IPC: H04M1/64
Filed: 1925-06-17
Abstract: 258,021. O'Reilly, H. P. June 17, 1925. Electric and magnetic machines. - A telegraphone is constructed with two sets of reels and records for alternate use, separate means for rotating the sets in opposite directions, and means for selecting and locking the rotating means as desired. Provision is made for stopping automatically one set of reels on completion of the record, for manually starting the other set, for oscillating and raising and lowering the talking head of an operative set so that it moves parallel to the axis of the reels. and for effecting a quick rewind of the record wire or equivalent. A casing 1, Fig. 4, supports two similar pairs of opposing reels 56, 57, one of each pair being driven to draw the record wire &c. off the opposing reel and through a talking head 61, which is pivoted in a forced bracket 75 adjustably mounted in a sleeve 74 telescopically engaging a rod 70 rocking on a pivot 73. The rod 70 is rocked by a cam 68 driven from a worm on the reel spindle and returned by a spring 72, and trunnions 77 in the sleeve 74 move in curved guides 79 so that the head 61 moves parallel to the reel axis. Either reel of each pair may be driven from a common motor driving by belt gear two friction discs 11, 12, Fig. 2, arranged respectively between friction discs 13, 14 and 15, 16 for the two sets. The discs 13, 14 of one set are fixed on a shaft 17 which can be moved longitudinally, to engage either of the discs 13, 14 with the driving disc 11, by completing a circuit through one or other of the electromagnets 23, 24 whereby a pivoted lever 21 is rocked to move the shaft 17 and is locked bv the core of one or two electromagnets 33, 34. The shaft 17 now drives by a belt 45 a pulley 43 freely mounted on a stationary sleeve 87, Fig. 9, on a spindle 40 carrying the reel support 100. The pulley 43 has a free-wheel ball clutch engagement with a flange 89 of a pulley 47 mounted on the sleeve 87 and connected by a belt 49 with the opposite reel, and also a free-wheel ball clutch engagement with a flanged disc 90 fixed to the spindle 40, the ratchets 92 for clutching the balls 96 being oppositely arranged so that one clutch is operative when the other is free. Either of a pair of reels can thus be driven according to the position of the lever 21. When the record is almost completely drawn off one reel, a spring-pressed pivoted lever 80, Fig. 4, bearing against the reel depresses a switch stud 85 to complete a circuit through the magnets 33, 34, so as to release the lever 21 whereby the driven disc 13 or 14 is released from the driving disc 11. The disc 11 may be adjustable radially on the discs IS, 14 for varying the driving speed. The rewinding drive may be quicker than the playing drive by suitably changing the sizes of the pulley 47 and the pulley which it drives through the belt 49. The reels 56, Fig. 9, are mounted on hubs 100 which are fixed on the spindle 40 and provided with longitudinal slots 101 with any one of which a rib 102 on the reel can be engaged.
Patent GB-1075153-A (GB)
Title: False twisting textile yarn
Inventor: SCRAGG FREDERICK
IPC: D02G1/06
Filed: 1963-04-20
Abstract: Yarn is false-twisted by a rotating member floatingly supported free from contact with mechanical bearings in a magnetic field and magnetically constrained against vertical and horizontal displacement.  Yarn is withdrawn from a supply package by driven rollers, and passes upwardly over a heater, through a false-twist device, through a bore in an electromagnet, and through further driven rollers, and is taken upon a drum-driven package.  The relative speeds of the two acts of driven rollers determine the degree of extension or contraction imparted to the yarn.  The lower pair of rollers act as twist-stoppers.  The false-twist device comprises a pin in a bore through a disc or through a cylindrical or spherical member (15, Fig. 1 not shown) made at least partly of magnetisable material.  The member is rotated by a rotating magnetic field produced by two pairs of coils (35, 36 Fig. 3 not shown) spaced around it, the axes of each pair being parallel and at right angles to the axes of the other pair. Alternating potential, derived from an oscillator (31, Fig. 2, not shown) fed with A.C. is fed to a phase-shifting circuit (32) which supplied two alternating potentials with 90 DEG  phase difference to the coils through successive amplifiers (33, 34).  The member (15) is supported against horizontal displacement by detector coils (37, 38 Fig. 3) not shown, which can change the field produced by coils (35, 36); the member is supported against vertical displacement by the pull of an electromagnet (23 Fig. 1, not shown) which together with the upward tension in the yarn offsets the weight of the member.  If the member should rise or fall, the movement is detected by a ring (27) below the member, which can change the current in the coil of the electromagnet. Finally, the member is supported against tilting by the yarn itself.
