Title: Improved fluid sealing device
IPC: F16J15/44
Filed: 1959-11-09
Abstract: 863,527. Stuffing-box substitutes. ALLISCHALMERS MANUFACTURING CO. Nov. 9, 1959 [Nov. 17, 1958], No. 37968/59. Class 122 (5). A fluid sealing device 19 between the shaft 14 of a centrifugal pump 11 and its housing 16 comprises an annular member 21 mounted on the shaft for axial movement relative thereto under the action of a pressure differential on the end faces 34, 38 and 42 of the member so as to provide an end sealing gap 37 between the faces 34, 38 and the face 36 of a stationary member 32, and an axial sealing gap 24 provided between the member 21 and the housing 16 in fluid communication with the end sealing gap and in series therewith in the direction of fluid flow between the zones of different pressures so that, in operation, fluid flows from the zone of high pressure acting on the end face 42 through the axial sealing gap 24 to the end sealing gap 37 and thereby maintains the latter at a constant dimension. The axial sealing gap 24 is defined between the annular member 21, which is coupled by a bellows 22 to a member 17 secured to the shaft, and a number of radially movable rings 27 which together form a labyrinth-type seal for determining the pressure differential between the two end faces 42 and 34, 38 of the annular member. In operation, when the pump is started, fluid passes through the gap 24 into a chamber 39 where the pressure of the fluid then builds up until it equals that acting on the end 42 and since the area of the face 38 of the annular member is arranged to be greater than the area of the end face 42, the surface 34 is lifted away from the surface 36 of the member 32. The fluid then flows through the gap into a low-pressure zone 46 thereby causing the pressure in the chamber 39 to drop below that acting on the end 42 but since the surface area 34 is now additionally subjected to this pressure, the gap 37 is maintained constant. Instead of using the fluid medium being pumped as the sealing medium, a fluid medium may be introduced for this purpose at a pressure above that of the pump system.

Title: Control means for hydrostatic steering systems and the like
IPC: B62D5/093
Filed: 1973-08-10
Abstract: 1441166 Hydrostatic steering systems DANFOSS AS 10 Aug 1973 [14 Aug 1972] 37989/73 Heading B7H In hydrostatic steering control means 3 having a control valve 14 which is actuated by a followup device 12 in response to rotation of a steering wheel 11 relative to a metering motor 13, transmission of shocks from a steering cylinder 4 back through the metering motor 13 to the steering wheel 11 is prevented by a non-return valve 23 which is located in a supply line 22 from a pump 1 to the valve 14 downstream of a by-pass passage 19 and comprises a closure member 27, Fig. 2, carried by a stem 28 slidably mounted in a valve insert 31, 32, 33 in which there is also mounted an emergency control valve 34 which opens to permit manual actuation of the metering motor if the pump 1 fails. The control valve 14 includes relatively rotatable valve members 15, 16 having neutralposition openings 17 and reversing openings 20, the neutral-position openings co-operating as the valve is displaced from a neutral position to progressively restrict flow through the bypass passage 19 from the supply line 22 to a return line 6, and the reversing openings 20 simultaneously establishing a flow path from the supply line 22 through the metering motor 13 to the steering cylinder 4. The emergency control valve 34 is normally maintained in a closed position by supply line pressure acting on a rear face 44 thereof through a flow-restricting passage 42, but opens automatically when manual actuation of the metering motor 13 creates in the supply line 22 a pressure which is lower than that in the return line. An excess pressure valve 35 normally held closed by a spring 48 is subjected to the pressure in the supply line 22 through the passage 42 and passages 54, 55 in the valve insert and the stem 28. If there is excessive pressure in the supply line 22 the valve 35 opens with the result that the pressure acting on the rear face 44 of the emergency control valve 34 is reduced and that valve opens to provide a large relief flow passage between the supply line 22 and the return line.

Abstract: 1,221,989. Valves. R. S. YOLPIN. 8 Aug., 1968, No. 37991/68. Heading F2V. In a gate valve having a main housing 10 and a bonnet 17, actuation of the gate 23 is effected by a shaft 26 which is non-rotatably reciprocable by an actuator 29, 32, the shaft having slidably mounted thereon a seal piston 46 which serves to isolate the actuator from line pressure and furthermore, to define within the bonnet a lubricant chamber 18a, 52, 51, 30, 53, 19a to which lubricant may be supplied through a fitting 56 and from which the same may be released via a vent 58. The piston 46 attains a position within the bonnet at which the fluid forces acting on its opposite faces and due to line pressure and to the lubricant are equal. The actuator has a bearing 43, 44 which is disposed, with slight clearance, within a gap defined by two bonnet shoulders 40, 41. The gate is formed with a notch 65 which, when the gate is in its lowered, valve closed position, serves to bring into communication annular seat grooves 63, 64 and corresponding passages 61, 62, the passages leading from reservoirs 59 60 which contain lubricant sealant and pistons 67, 68, which like piston 46, are responsive to line pressure, such pressure being applied to the pistons by virtue of leakage at the upstream side of the gate when the latter is in the closed position.

Abstract: 970,541. Bearings. ROBERT HYDE & SON Ltd. Nov. 9, 1961 [Nov. 9, 1960], No. 38548/60. Heading F2A. A bearing shell has a bearing surface 2 to receive a journal 3, an elongated trough 6A in an upper surface of the shell above the surface 2 (Figs. 1 and 4) to receive liquid lubricant from delivery means at a point adjacent to one end thereof and passages, e.g. 14 (Fig. 2). through which lubricant can be delivered to the bearing surface of the journal 3, having openings 13a or 13b, for flow of lubricant into them spaced along the trough length and above its base so that it is a reservoir for lubricant, the flow through the respective openings being thus determined by their disposition in the trough length from the delivery point and/or their heights above its base. The openings 13a, 13b lie in the surface of a platform 12 in the trough (Figs. 1 and 2). The platform surface has gradients made to assist in even distribution of the lubricant to the openings 13a, 13b. The trough 6A has its base higher at one end than at the other and the delivery means delivers into the higher end, and a buttress wall 17 (Fig. 2) in the trough 6A prevents direct flow into the opening 13a or two or more openings thereat. Lubricant is delivered to the trough 6A through the agency of a paddle wheel on the outer end of the journal 3 from the sump of an axle box.

IPC: H01L21/00
Filed: 1957-12-16
Abstract: 866,932. Semi-conductor devices. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 16, 1957 [Dec. 26, 1956], No. 39032/57. Class 37. A semi-conductor device such as a rectifier, is produced by placing a semi-conductor crystal on a metal wafer resting on the contact surface of an electrode, the whole being subjected to pressure while electric current is passed through the assembly to fuse the wafer to the electrode, and to the crystal at the eutectic temperature, thereby to form an ohmic contact. A rectifying electrode comprising significant impurity is then fused to the opposite surface of the crystal by passing current between the two electrodes, thereby forming a PN junction. This assembly is then surrounded by a glass tube, the ends of which are heated inductively so that they become sealed to the electrodes to form an enclosure. Fig. 1 shows the completed device comprising electrode 1 carrying metal wafer 3 and semi-conductor crystal 2 and rectifying electrode 5 which is spot-welded to connecting- lead 4. The assembly is surrounded by glass enclosure 7 and may have an outer protective insulating and opaque coating 8. In the inductive heating process, each end of the glass tube is surrounded by a coil and a metal insert is added which serves to heat the glass until the resistivity of the glass falls sufficiently for the glass itself to be susceptible to inductive heating. The semi-conductor crystal 2 may consist of germanium and the metal wafer 3 of gold. Electrode 1 may consist of an alloy of 51% Ni and 49% Fe or 43% Ni and 57% Fe sheathed in borated copper or 29% Ni, 17% Co, 3% Mn and 51% Fe. Electrode 5 may consist of gold or a platinum-ruthenium alloy with an acceptor such as indium. Details of apparatus suitable for performing each step of the process are given.

Abstract: 1482577 Seismic exploration SOC NATIONALE DES PETROLES D'AQUITAINE 10 Sept 1974 [14 Sept 1973 27 Aug 1974] 39439/74. Heading G1G A multi-trace seismic record is obtained by a field procedure in which the source and receiver spacings are such that the lateral interval between consecutive depth points is not greater than the inverse of twice the maximum wave number of seismic waves to be recorded. A spatial-frequency, i.e. wave-number, k, analysis of the record is then made to identify unwanted, e.g. coherent, noise and the record is filtered to remove those spatialfrequencies associated with the noise. In embodiments described, a source at the point of intersection of two rows of receivers, or vice versa, is used to provide multiple coverage of common depth points (CDP). A velocity analysis of the CDP traces is made after static corrections have been applied; then dynamic corrections are applied using the velocity information. The spatialfrequency analysis is made by defining timewindows across the traces, in each time-window sampling the trace amplitude to obtain an amplitude-versus-depth point function, and determining the spatial-frequency spectre of the various functions. Based on this analysis, k, filtering alone or together with temporal-frequency (f) filtering is applied to the traces to remove noise. The filtered traces are then stacked to form a seismic section. A separate section showing noise only may be recorded by use of complementary filtering. In alternative embodiments the order of the steps of applying corrections, filtering and stacking is different. The filtering can also be used to remove unwanted refraction events from the traces.
