Abstract: 942,795. Valves. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. May 26, 1960 [June 2, 1959], No. 18777/59. Heading F2V. In a butterfly valve the disc and the seat are relatively movable towards and away from each other and the actuating mechanism includes a linearly displaceable member which extends out of the valve body. In the first embodiment the closure member 1 which cooperates with a seat 3, Fig. 2, is carried by a pair of trunnions 2, each of which is carried by a block 5 displaceable in a slot 6 in the valve body 4. The slot 6 is lined with a porous bearing material impregnated with polytetrafluoroethylene. Each block 5 is connected to a shaft 8 which is keyed to a screwed bush 15 and extends into an external guide 10. A metallic sealing bellows 19 is welded to the shaft 8 and to the bush 15. Each shaft 8 has a pair of trunnions received in enlarged holes in spaced levers 20, Fig. 1, which are connected by a cross-bar 22 to a screwed shaft 23 connected to a hand wheel 24. Two springs 36 extend from the closure member to a T-sectioned bracket 33 located within the body 4 and carrying a roller 34. A stop 38 defines the seating position of the closure member. In operation, the valve is opened by rotation of the hand wheel 24 to effect linear displacement of the shafts 8 and block 5 via the shaft 23 and levers 20 to withdraw the closure member 1 from the seat 3. When the closure member 1 meets the roller 34 it is pivoted to the open position. Re-closing is effected by reverse rotation of the hand wheel, the member 1 being pivoted by the springs 36 before being seated. A duct 39 extends from the seat to a screwed connection 40 to allow of gas sampling as a check for leakage. In the second example, Fig. 9, the valve seat 42 of polytetrafluoroethylene is carried by a housing 44 slidable axially within the valve body 47, 48. Three equispaced lugs 45 on the housing 44 project through slots 46 in the body part 48 to receive rods 74 of hydraulic jacks, the pistons of which are loaded by springs 78. The seat housing 44 is sealed by two bellows 80 and a sampling duct 81 is again provided. The closure member 41 is pivoted to a bracket 51 carried by a sleeve 50 within the body part 47. A hinged link 53 is pivoted at one end to a lug 54 on the valve member 41 and is rigidly attached at the other end to a pin 55, one end of which extends through the valve body into an actuating mechanism housing 57, Fig. 10, where it is attached to a link 58 connected by a link 66 to a linearly movable screwed actuating member 61 which extends through a sealing bellows 72. In operation, to open the valve, the valve seat is withdrawn from the member 41 by actuation of the jacks 73 to move the housing 44. The actuating mechanism 59 is then operated to pivot the valve member. Valve closure is effected in the reverse sequence.

Title: Improvements relating to electrical pulse generators
IPC: H05H1/02
Filed: 1957-06-20
Abstract: 842,026. Reciprocating generators. BRAILSFORD, F., and METROPOLITAN-VICKERS ELECTRICAL CO. Ltd. June 16, 1958 [June 20, 1957], No. 19516/57. Class 35. Heavy current impulses, e.g. for nuclear discharges, welding, or arc discharges, are generated in a coil A attached to the skirt of a piston P which is thrust into the radial field between the poles B of an electromagnet by the injection of steam or compressed air into the cylinder C. It is arranged by suitable mechanism, e.g. a cam-shaft, controlling inlet and exhaust valves D, E, that the piston is accelerated over distance x 1 , and valve D is closed and exhaust valve E is opened. The coil now enters the magnetic field, the resultant induced current producing a damped oscillation having a first swing to x. At this point the recoil may be damped by the admission of further steam at valve D for a brief period, thus bringing the piston to rest without permitting reversal of current. Contacts operated by the piston may be used to apply a resistive load to the generator in the event of the normal load failing. Compensating coils carrying the load current may be secured to the pole-faces. The piston may be returned to its starting position by means of an auxiliary piston connected through a piston-rod. The moving coil is connected through suitable sliding contacts to the outside circuit. The moving coil may be of strip wound on edge or of hollow circular crosssection, and the turns may be axially spaced to reduce inductance. Specification 830,252 is referred to.
