Title: Clamped body replacement tool
Inventor: HOPE RODNEY CHARLES
IPC: E21B41/04
Filed: 1988-08-22
Abstract: A fluid operated tool 30 (Fig. 4) for use in replacing a body 16 (e.g. wing valve) clamped between facing platens 27, 28, has an open ended tubular member 31, through which the body 16 can pass. Coplaner support arms 33, 34 extend from opposite sides of member 31 and at the end of which are hydraulic piston and cylinder arrangements 35, 36 for insertion between the platens 27, 28. On actuation, the pistons 37 of the piston/cylinder arrangements 35, 36 are extended to engage the platens 27, 28 and overcome the clamping forces exerted on the body 16 thereby permitting the body 16 to be removed and replaced by way of the tubular member 31. The tool may be used subsea with a submersible to handle it and provide hydraulic power. The pistons 37 may be extended by hydraulic fluid pressure. Alternatively a piston member may be extended by means such as a nut on a rotating lead screw or by means of an axially displaced rotating jack with fluid turbine or electric motor activation. The tool may be guided between the platens 27, 28 by tapering projections 43. Member 31 may include internal surface constructions 31' to cooperate with stem portion 26 of the valve. <IMAGE>

Title: Producing metal-coated vias
Inventor: SPARROW JOHN ANDREW
IPC: H05K1/09
Filed: 1988-09-03
Abstract: A method is described in which groups 17 of close-spaced, discrete, small diameter, vias 11 are cut in a substrate 3 of ceramic material using a pulsed laser 1. Each via is cut with a single laser pulse. This eliminates residue deposition and consequential problems in metallisation. This method is applicable to both thin and thick film processing. Examples are given for thin film processing in which vias of diameter 40 to 60 mu m, and 90 to 110  mu m, are cut in ceramic substrates of standard thicknesses 0.24mm and 0.63mm, respectively. An example is also given for thick film processing in which vias of diameter 150 to 170 mu m are cut. <IMAGE>

Title: Pumps with pivotably mounted rotor blades
Inventor: BOOTH RAYMOND
IPC: F04D29/22
Filed: 1989-04-01
Abstract: A centrifugal pump comprises a rotor having blades pivotable about axis P parallel with axis of rotation A of rotor. The blades comprise an integral blade portion 24 and shaft 26 carried by bearing members (34), assembled with the rotorbody by push-fit assembly methods. Stop means, eg. a collar 44 keyed to shaft 26, prevents rotation of the blade portion 24 beyond extreme positions at either side of a radius of the rotor passing through the pivot axis P and at the same angle relative to the radius for either direction of the rotor. The collar 44 has projections (50, Fig. 5) which engage a projection (52, Fig. 5) of the rotor to limit pivotting of the blade. Irrespective of the direction of rotation of the rotor (10), fluid is drawn through an axial inlet (16, Fig. 2) and delivered through peripheral outlets (20, Fig. 1). Collar (44) can be exchanged for one in which projections (50) are at different angles to one another to change the extreme positions of the blade portion 24. <IMAGE>

Title: Seal, particularly for linear displacement transducer
Inventor: MASOM RONALD ALFRED
IPC: F16J15/52
Filed: 1989-12-14
Abstract: A seal 10 for a linear displacement optical transducer has a tubular flexible bellows 11 which is jointed at one end to a movable carriage 2 supporting an optically encoded track 8 and which is movable along a cylinder 3 supporting an optical read head 7. The bellows 11 extends within the cylinder 3 and has its other end sealed to an open end 6 of the cylinder. A compensation chamber 20 is sealed to the outside of the cylinder 3 to enclose a major part of the length of the bellows 11 and forms a sliding seal 27 with a push-rod 5 coupled with a carriage 2. The bellows 11 encloses a first volume of a dry inert gas within the cylinder 3 to one side of the bellows and a second, similar volume of gas on the other side of the bellows and in the compensation chamber 20. Displacement of the carriage 2 causes only a small change in pressure across the bellows which is accommodated by flexure. The compensation chamber 20 isolates the bellows 11 from atmospheric pressure change and ensures that temperature change affects both volumes equally, minimizing pressure difference across the bellows.

Title: Riser post arrangement for elevating access platform
Inventor: CULLEY MARK
IPC: B66F11/04
Filed: 1990-02-09
Abstract: Access platform apparatus has modified geometry whereby a more compact assembly can be achieved in the stowed or transport position. This is achieved by arranging that the riser post 20, which interconnects the riser boom 22 and the platform boom 24, extends upwardly and forwards at an inclination of more than 3 degrees to the vertical, instead of the usual generally vertical attitude. As a result, in the stowed position, the platform boom main pivot 52 is located significantly further forwards than is otherwise possible, thereby reducing the overall length of the apparatus. <IMAGE>

Title: Method of plotting surfaces in a volume
Inventor: KESKES NAAMEN
IPC: G01V1/20
Filed: 1991-01-29
Abstract: A method enabling the plotting of surfaces in a 3D volume which is particularly applicable to the plotting of horizons in 3D seismic data acquisition, comprises decomposing the XY plane into bins 2 for which a vertical seismic trace 3 represented by a column, is associated. A Peano-Hilbert curve is drawn according to the order defined by the Peano-Hilbert Key so as to pass through each node on the XY grid and the correspondence R between the Peano order associated with the curve and the column coordinates is established. The columns are reclassified according to that order and an automatic plotting program which enables the extrema correlating one column to the next to be connected by segments is applied to the 2D picture (P, Z) obtained. The inverse relationship R<-1> is applied to each segment and the resulting surface elements are regrouped and displayed. The method avoids phase shift discontinuities between pictures of the same horizon. <IMAGE>

Title: Bale accumulator
Inventor: BROWN ARTHUR WILLIAM GRAY
IPC: A01D85/00
Filed: 1991-07-18
Abstract: A bale accumulator has a fixed part 10 and a movable bed part 11 shorter than the length of the bales 20 to be accumulated enabling movement of the movable part 11 of the bed such that an end of the bales 20 comes into contact with the ground facilitating removal of an accumulated array of bales from the accumulator. Since the movable part 11 of the bed is shorter than the bales 20 to be accumulated, trigger means 23 are positioned in order to operate bale movement means 26, 27 and bale release means (36, Fig. 8) so as to be activated by the rear end of a bale being delivered onto the accumulator. The arrangement allows a smaller bale accumulator requiring less material and hence weight and by enabling the bale to be dragged from the accumulator the bed can be at a lower level than was previously necessary since the angle of the bed in its bale delivering position does not have to be as steep as was the case in known bale accumulators. <IMAGE>
