Patent GB-846335-A (GB)
Title: Improvements in and relating to semi-automatic control gear of the hydraulic servo-control of hydraulic machines, particularly machines for casting metals under pressure
IPC: B22D17/32
Filed: 1958-01-10
Abstract: 846,335. Hydraulic machines; valves. CHARVAT, J. Jan. 10, 1958 [Jan. 11, 1957], No. 1066/58. Classes 69 (2) and 135. A semi-automatic hydraulic control arrangement for casting machines provides for manual control of the insertion of the cores, closing of the mould and injection of metal under pressure, and provides for automatic release of the injection pressure, opening of the mould and removal of the cores. Valves 2, 3 and 4 control the core, mould and injection operation respectively, and are actuated by cams on a common shaft 7 rotatable by a handle 15. Valve 4 is controlled by a two-part cam having a part 10 fast on the cam-shaft and a part 11 loosely mounted on the cam-shaft. Moving handle 15 manually in a plane transverse to the axis of the cam-shaft from an initial position I to a position II causes a cam 8 to depress valve 2 to insert the cores. In position III a cam 9 allows the valve 3 to rise to close the mould. When the handle is turned to a position IV cam 10 allows valve 4 to rise to supply liquid to a cylinder 24 for injecting the metal. Liquid is also supplied to a movable cylinder 21 which co-operates with a fixed piston 19 and is fast with a cylinder 22 having a stationary piston 20. A rack 18 is fast with cylinders 21, 22 and meshes with a pinion 16 which can be clutched to the cam-shaft 7. In position IV the pinion is declutched, and rack 18 is moved idly upwards against the pressure of an accumulator 23 at a rate controlled by a throttle 5. Moving the handle to a position V coaxial with the camshaft clutches the pinion 16 to the cam-shaft, and further upward movement of the rack rotates the cam-shaft and a tooth on cam 10 moves cam 11 until it depresses valve 4, in which position of cam 11 a spring-urged non- rotatable finger 12 engages a recess in the cam to hold it stationary. Depression of valve 4 opens cylinder 24 to exhaust; cylinder 21 is thus opened to exhaust and the rack is moved downwardly by the accumulator pressure acting on cylinder 22 and at a rate controlled by a throttle 6. This rotates the cam-shaft to successively actuate valves 3 and 2, to open the mould and remove the cores, and finally cam 10 disengages the finger 12 from cam 11 and the tooth of the cam moves cam 11 to move the recess out of alignment with finger 12. The lever is then returned to position I ready for another cycle.

Title: Improvements in or relating to electric discharge tubes for use at extremely high frequencies
IPC: H01J23/28
Filed: 1951-01-16
Abstract: 708,429. High-frequency discharge apparatus. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Jan. 16, 1951 [Jan. 19, 1950], No. 1195/51. Class 39(1) A tube for generating electromagnetic waves having a wavelength of the order of 1 cm. to I m. is characterized in that when the tube is in operation an electron beam passes through apertures in successive transverse conductors which are spaced apart at substantially equal intervals and are secured alternately to two longitudinal conductors, the transit time of the electrons between two successive transverse conductors being less than one half-period of the oscillation produced. Alternatively, the beam passes through successive transverse conductive loops which are secured alternately to the opposite edges of a longitudinallydirected slot in a conductive arid preferably circular cylinder. In the arrangement shown in Figs. 1 and 2, the discharge tube comprises a cathode 1, acceleration electrode 2 and anode 7. Strips 8 and 9 are secured respectively to the upper and lower walls 3 and 4 of a prismatic waveguide resonator having side walls 5 and 6. In an alternative embodiment one of the side walls is omitted and the strips are located adjacent the open side of the waveguide. In the embodiment shown in Fig. 4 the strips are secured to two L-shaped conductors 13 and 14 forming a trough-shaped resonator with capacitive coupling between the conductors at the bottom of the trough. In a modified arrangement, Fig. 6, apertured strips 14 and 15 are secured to conductors 16 and 17 which are connected inside the tube by a fixed short-circuiting bridge 20 and are extended through the envelope 19 of the tube and short-circuited by an adjustable external tuning bridge 18. The fixed bridge 20 may be omitted and the strips located adjacent the open ends of the conductors. In a further arrangement, Fig. 7, rings 22 and 23 are secured alternately to the opposite edges of a longitudinally directed slot in a cylindrical resonator 21. In all the arrangements the longitudinal dimension l of the longitudinal conductors or resonator, the energy e Vo of the electrons in electron-volts, the wavelength # of the waves generated, and the number N of spaces between adjacent transverse conductors or loops preferably satisfy the equation: In the arrangements comprising two longitudinal conductors, these may together form a Lecher resonator carrying oscillations at right angles to the beam, and the effective length of the Lecher system at right angles to the electron beam should be an odd or an even number of quarter-wavelengths according as to whether or not the system is short-circuited.

Abstract: 546,350. Valves. PUMP ENGINEERING SERVICE CORPORATION. Jan. 31, 1941, No. 1318. Convention date, Jan. 17, 1940. [Class 135] [Also in Groups XXVI and XXXIII] A device for equalizing the flow of a number of fluid sterams particularly applicable for controlling the flow of fluid to a pair of remotely located fluid piston motors operating aircraft landing flaps, wing tip floats, landing gear and other units comprises a valve device in each conduit, both valves being loaded towards their seats by pressure fluid from whichever conduit on the outlet sides of the valve is under higher pressure. As shown in Fig. 1, landing flaps 10, 11 are actuated by pistons 12, 13 under the control of a series of valves 16a, 16b, 16c. 16d, selectively actuated by a cam-shaft 16e associated with a non-return valve 16f in the exhaust conduit and relief valves 16g. The conduit 22 supplying the outer ends of the power cylinders is fitted with the flow equalizing device of the present invention which is shown in Figs. 2 and 3. Fluid entering by the pipe 22 is divided into two streams by a flow divider comprising two pairs of meshing gear wheels 91 mounted on a common shaft. In order to maintain equal back pressures in the outlet conduits 23, 24 each conduit is fitted with a valve 48 connected by a ported tubular part 49 with a spring-loaded piston 51 working in a ported liner 33 formed integrally with a screwed cap 37. The pistons are a slack fit in the liners and are fitted wtih cup leather packings 53. The spaces above the pistons are interconnected by ports 66, annular chambers 67 and a connecting passage 68 leading to a passage 71 fitted with a spring-loaded valve 76 having a spindle 77 loosely fitting in the passage and a spindle 78 adapted to act as a stop. When fluid is passing through the conduits 23, 24 to conduits 43, 44 fluid passes one or both of the pistons to establish a pressure above both the pistons equal to the higher of the pressures in the conduits 43, 44. When fluid is exhausted trom the outer ends of the power cylinders it passes from the conduits 43, 44 through ports 54 in the tubular parts of the valve and through spring- loaded non-return valves 56 to the conduits 23, 24. At the same time fluid above the pistons is exhausted through the spring-loaded valve 76 and port 73 to the conduit 23 so restoring the pressure-loading to its original condition.

Title: Well operations
IPC: E21B33/043
Filed: 1963-07-24
Abstract: 998,037. Wells &c. CAMERON IRON WORKS INC. July 24, 1963 [May 28, 1963], No 1741/65. Divided out of 998,036. Heading E1F. Casing 36 is hung from a seat 31 and sealed in a wellhead 25 by severing the casing between the seat and the adjacent casing collar 37, removing the severed upper portion of the casing, lowering a slip assembly 42 onto the seat, straining the casing and releasing it to cause the assembly to suspend the casing, and forming a seal between the wellhead and the casing. The method is particularly applicable to the completion of sub-aqueous wellheads in which the casing has become stuck as it is lowered into the well. A cutter 38 is lowered on a pipe 41 through the casing to the level of the wellhead, the casing being enclosed by a marine conductor (not shown) and blowout preventers 28. The upper portion of the casing is severed and removed, and the slip assembly is lowered onto the seat by means of a tool 43 which is then removed. The pipe 41 which is connected to the casing by the cutter 38 is raised to tension the casing to permit the slips 51 to grip the casing. The cutter 38 and pipe 41 are removed, and cutters 52 are lowered into the wellhead to cut the casing to its correct length, a spacer 55 being used. After the cutters 52 have been removed a seal assembly 57 (Fig. 9) is lowered into the wellhead on a tool 58. The seal assembly is rotated to anchor it to the slip assembly by hooks 62. Further rotation of the tool 58 causes an intermediate part 67 to screw onto a lower part 64 of the assembly to force a seal 71 to engage the casing. Continued rotation of the tool 58 shears a pin 80 to permit an upper part 66 to rotate relative to the intermediate part to press a seal 74 against the wellhead and set slips 78. The tool 58 is released, and should further drilling of the well take place a seat 81 for further casing forms a guide for the drill. In a modification of the seal assembly (Fig. 13, not shown) the slips are free to move under gravity and are placed below the seal 74, the shear pin being dispensed with.
