Title: Well devices
IPC: E21B23/02
Filed: 1959-08-10
Abstract: 924,708. Oil wells. J. V. FREDD. Aug. 10, 1959, No. 27331/59. Class 85. A device for anchoring and supporting well devices, e.g. a length of extension tubing 75, or temperature or pressure recorders, at a predetermined position in a well flow conductor, comprises locking means which are positively held in locking position by a longitudinally movable member which itself is releasably locked in locking position. The device consists of a mandrel 10 having an upper section 11, a lower section 12 and a central bore 13. Positioning and locking keys 16 are carried by a member 15 which consists of top and bottom rings 17 connected by ribs 18. The keys 16 are urged outwardly by springs 24 and are shaped to project into correspondingly shaped grooves 38, 39 when the device, being run into the flow conductor, is arrested by shoulders 41 on the keys reaching a shoulder 34 on the landing nipple 40. Each of the keys has lateral apertures 29, 44 and an inclined drain aperture 45a. To lock the device against upward movement from its located position, dogs 45 are mounted on the upper section 11 of the mandrel and are forced into a locking groove 46 in the nipple 40 by the camming action of a sleeve 57 when it is forced down by jars from the running-in tool. The dogs 45 project through windows in a cage 49 screwed at 14 on to the mandrel section 11. The dogs have hooked ends 47 which extend into a groove 48 in the cage 49, and the camming action is effected by the bevelled ends 55 of the strips between the windows of the sleeve 57 sliding over inclined surfaces 54 on the dogs which are held in the locking groove 46 by further downward movement of the sleeve 57 to bring the enlarged portion 61 into contact with the surfaces 54a of the dogs 45. When the sleeve 57 is fully depressed, an inwardly projecting detent 68 on the cage 49 snaps into a groove 69 in the sleeve 57 and prevents unintentional upward movement thereof. The running tool is released from the device by downward jars which shears a retaining pin, and is then removed. The device is removed by a retrieving tool which engages under the flange 74 and pulls up the sleeve 57, the detent 68 yielding to permit this; the dogs 45 being thus released and the device being pulled up, the bevelled surface 31 of the keys 16 forcing them inwardly when necessary. In a modification, the dogs 45, separate from the keys 16, are dispensed with, and the keys are shaped to land on a circular ledge and to move outwardly into the locking groove in the landing nipple. They are retained positively in the locking groove by the camming action of a sleeve, corresponding with the sleeve 57, which is forced down by jars from the running tool, which first breaks a shear pin, and is releasably locked in its lowest position by a spring-pressed detent. The device is removed, as before, by upward pulling with a retrieving tool.

Title: Improvements in and relating to a locking assembly
IPC: E05B65/46
Filed: 1968-06-11
Abstract: 1,206,489. Releasable fastenings. COMMISSARIAT A L'ENERGIE ATOMIC. 11 June, 1968 [12 June, 1967], No. 27646/68. Heading E2A. An assembly comprises a first member 2 having a first aperture 6 and a locking device for locking a lug 1 carried on a second member 3 when in locked position in relation to the aperture, the locking device comprising a yoke 8 secured to the first member adjacent the first aperture and on that side of the first member remote from the second member when locked thereon, a locking member 10 carried by the yoke and having a first portion 11 extending through a second aperture in the first member and a second portion 12 forming a stop for holding the lug in locked position relative to the aperture, a cam 13 secured to the looking member, the cam being biased in the direction of the first member and the looking member being biased from an inoperative position to a locking position and stop means 15 co-operating with the cam for releasably retaining the locking member in its inoperative position. In the construction shown the aperture 6 is rectangular and the lug 1 is of rectangular shape in crosssection, with a slot extending into it from one side. The lug is passed horizontally into the aperture until a shoulder which is an extension of one side of the slot comes up against the surface of the member 2 to limit further horizontal movement, then the lug is moved vertically downwardly to engage it with the portion of the member 2 surrounding the aperture. The horizontal movement of the lug into the aperture causes its front end to engage the portion 12 of the member 10 to slide the member 10 in a direction which compresses a biassing spring 14; the subsequent downward movement of the lug releases the member 10 which, urged by the spring 14, returns to its original position with the end portion 12 above the lug to lock the lug in position. The return movement causes the cam 13 to engage the stop means 15 which is a leaf spring and stress it. To release the lug the portion 11 of the member 10 is pressed to slide the member 10 to the left as shown to compress the spring 14 and this movement releases the spring 15 and since movement of the member 10 by pressure on the portion 11 moves it rather more than the movement caused by the lug 1 during the fastening operation the spring 15 engages a vertical end surface of the cam and prevents return movement of the member 10 to the right. Since the portion 12 no longer prevents upward movement of the lug 1 it is now moved upwardly and during the upward movement it engages an end portion of the spring IS and so frees the member 10 so that it can move to the right again to its initial position when the lug 1 is withdrawn from the aperture in the member 2.

Title: Improvements in electric circuit arrangements
Inventor: RANDALL HENRY
IPC: H02P1/58
Filed: 1957-09-04
Abstract: 900,638. Master control of electric motors; fluid actuation of switches. ENGLISH ELECTRIC CO. Ltd. Dec. 4, 1958 [Sept. 4, 1957], No. 27925/57. Classes 38 (3) and 38 (5). A control system for the sequential operation of six electric motors, each of which motors is controlled by one of the contactors 10-15 comprises two auxiliary bus-bars 23, 24 which are alternately energized from a D.C. supply 16, 17 when a ganged switch 18, 19 is operated by the energization and de-energization of a contactor 22. Closure of the switch 18, 19 energizes the contactor 22 over the closed contact 10a, thus causing contact 22b to open and contact 22a to close after a predetermined delay thereby energizing bus-bar 23 and de-energizing bus-bar 24. Energization of bus-bar 23 now causes contactor 10 to become energized, thereby starting the first motor in the sequence. Energization of contactor 10 causes contact 10a to open to deenergize the contactor 22; contact 10b to close to maintain the contactor 10 energized and after a delay contact 10c to open. Deenergization of contactor 22 causes contact 22a to open to de-energize bus-bar 23 and after a given time delay contact 22b closes to energize bus-bar 24. Contactor 11 now becomes energized to start the second motor in the sequence, the energization of this contactor causing contact 11b to close to maintain the contactor 11 energized and after a delay con- 11c opens. Contact 11d also closes to prepare the circuit of contactor 12 and contact 11a closes whereupon contactor 22 is energized over contacts 12a, 11a. Energization of contactor 22 once more opens contact 22b and closes contact 22a whereupon bus-bar 23 is once more energized and bus-bar 24 de-energized. Contactor 12 thereupon becomes energized to start the third motor in the sequence, the contactors 13, 14, 15 being similarly energized as the sequence proceeds. Fig. 2 shows a pneumatically operated example of the contactor 22. A contact 22e movable to close either contact 22a, or 22b, is carried by a piston 22c movable in a cylinder 22d. Energization of the contactor 22 (Fig. 1), operates a magnetic valve 22f, whereupon compressed air is admitted to the cylinder 22d from a supply 22h. De-energization of contactor 22 operates the magnetic valve 22f to allow the air in the cylinder 22d to exhaust to the atmosphere through passage 22i. Delay between the openings and closings of contacts 22a, 22b are occasioned by air restrictors 22j, 22k or if the delays are of equal duration, these restrictors may be replaced by a single restrictor 221.

Abstract: 921,677. Adjusting vehicle height; road vehicle spring suspensions. GENERAL MOTORS CORPORATION. Aug. 2, 1961 [Sept. 12, 1960], No. 28045/61. Classes 108(2) and 108(3). A road vehicle suspension device comprises a piston-cylinder damper 20 with a flexible tubular diaphragm 62 forming a rolling seal fixed between cylinder 46 and a tubular member 25 rigid with the piston 32 to form an air-tight chamber 54 and a valve mechanism 80 operable by air pressure to permit charging of the chamber 54 with air and manually to permit release of air from the chamber until the pressure falls to a certain value. Damping is provided by valves 24, 43 in piston 32 and by valve 40 which restricts fluid flow from the inner chamber 41 to the reservoir chamber 47 but permits relatively unrestricted return flow. The valve mechanism 80 (Fig. 4), comprises valves 85 and 101 and a removable cap 97. The valve 85 comprises a valve disc 92 on a stem 91 which is depressed against the bias of spring 95 by the pressure of air from an air line fitted in place of the cap 97 when charging chamber 54 or manually to release air from valve chamber 81 and hence chamber 54. Valve 101 maintains a minimum pressure in chamber 54, dependent on the bias of spring 107. When charging the chamber 54 the pressure differential between chambers 81 and 54 bows resilient disc 102 downwards permitting air flow through passages 105 and 103 and line 76 to the damper 20. A pair of dampers in Fig. 1 are used with a pair of laminated springs 17 at the rear of a vehicle and act as auxiliary air springs the air pressure in which is altered to maintain the vehicle level when the load is changed.
