Title: Improvements in electromagnetic operating mechanism
IPC: G04C1/06
Filed: 1931-04-28
Abstract: 387,336. Switches, partly electromagnetic. DUBILIER CONDENSER CO. (1925), Ltd., Victoria Road, North Acton, London.-(Assignees of Dubilier, W. ; 72, Esplanade, New Rochelle, New York, U.S.A.) April 28, 1931, No. 12523. Convention date, May 2, 1930. [Class 38 (v).] An electromagnetic operating device applicable to clock-winding gear, ammeters, typewriters &c. comprises, a centrally pivoted armature carrying at one end a damping loop adapted to encircle the pole when the armature is attracted. As shown in Fig. 2, applied to a clock, the laminated armature 11, pivoted at 6, is provided with a rectangular loop 19 having an extension 23 to rock the arm 16 of a switch controlling the energizing circuit of the magnet coil 13. As the clock spring runs down the armature rotates to and beyond the position shown so that the switch is operated to complete circuit for the magnet which then restores the armature to its initial position. At the end of this movement the switch is again operated .to break the circuit and the loop 19 in its passage over the polepiece sets up an opposing force to damp the movement. In the modification shown in Fig. 4 the armature carries a contact spring 26 adapted to snap over an insulated head 31 on a spring-controlled rod 27 and complete the energizing circuit. As the armature is rocked to wound position the spring 26 drags the head and rod with it against the action of spring 29 until the spring 26 finally escapes from the head. In a further arrangement, Fig. 6, the armature winds the spring through the intermediary of a lever 40. The armature is acted upon by a spring 37 and the energizing circuit passes through a spring arm 45 normally keeping a contact 42 in engagement with a contact surface 41 on the lever. In the unwound position illustrated the circuit is completed through these contacts and through the lever bearing against a contact 38 on the armature. The latter now rocks counterclockwise to restore the lever to the horizontal whereupon a lug 46 depresses spring 45 to break the circuit. The armature is thus released and is returned to the position shown by the pull of the spring 37.

Title: Well safety apparatus
IPC: E21B34/08
Filed: 1971-05-03
Abstract: 1354899 Wells &c CAMCO INC 3 May 1971 [30 June 1970] 12628/71 Heading E1F A safety valve for use in well tubing comprises a tubular housing 42 having axially spaced seals 44, 46 and a telescopically movable member 52 having a plurality of pistons 56, 58, 60 co-operating with respective portions of the interior wall of the valve body and openings 62, 64, 66 to form expansible pressure chambers by which it is biassed downwardly in response to pressure in the annulus 40, surrounding the tubing, to force open a pivoted flap valve 48. The valve may be located in a tubing mandrel 12. The mandrel includes a passage 22 in which the valve is supported by latching dogs 90, and a passage 34 having openings 37 communicating with the annulus 40. Pressurized fluid in the annulus 40 passes via the openings 37 and passage 34, to the openings 62, 64 and 66 and depresses the pistons 56, 58 and 60 on the member 52 against the action of a spring 88 so that the flap valve is opened. The area of the lower end 86 of the member 52 is smaller than that of the upper end 84. Under normal flow conditions the flap valve is open. Reduction of the pressure in the annulus 40 allows the member 52 to rise and the flap valve closes under the action of a spring (not shown). Increase of pressure in the tubing below the valve beyond a predetermined value (e.g. if the well over produces) overcomes the effect of the difference in areas 86 and 84 and forces the member 52 upwards so that the flap valve closes. The seals 44, 46 prevent production from leaking into the annulus 40. The upper end of the passage 34 contains a plug 38 or a flow control unit for gas lift operations. When it is desired to retrieve the safety valve, the plug 38 &c is replaced by a blanking plug which seals off the openings 37. In a modifica tion, the mandrel is omitted and the valve is located in a section of tubing.
