Title: Method and device for regulating a pressure in a hydraulic system
Filed: 2008-03-17
Abstract: The present invention relates to a method for regulating a pressure in a hydraulic system for operating at least one actuator in a subsea installation, having a fluid supply line (102) connected to a source of pressurized fluid (101) at a remote location delivering fluid at a constant pressure to the subsea installation, comprising first and second control valves (103, 105) controlled by an electronic control unit (107), and at least one pressure sensor (106) and an accumulator (104) arranged between the first and second control valve (103, 105), where the pressure in the fluid supply line (102′) to the actuator is regulated by regulating the pressure in the accumulator (104) by adding fluid from the source of pressurized fluid (101) through the first control valve (103) if the pressure is too low or releasing pressure through the second control valve (105) to a fluid return line (120) if the pressure is too high and thereby establishing the desired pressure for operating the actuator. The invention also relates to a device for performing the method.

Patent GB-8528698-D0 (GB)
Title: Photolithography
IPC: G11B7/00
Filed: 1985-11-21
Abstract: Metal tellurium is vaporized under the atmosphere of oxygen gas and/or inert gas formed into a plasma by a high frequency power to thereby form a tellurium oxide (TeOx, 0 </= X </= 2) layer (9). The tellurium oxide layer formed in accordance with the present method is stabilized, and a suboxide having a high sensitivity which has been considered to be unsuitable as an optical recording medium due to the lack of stability can be utilized. High frequency power, gas pressure and vaporization speed of metal tellurium can be varied to thereby vary the value X of TeOx from 0 to 2. When the TeOx films whose value X thicknesswise is different are formed continuously within one and the same vessel and the vaporization speed is made to zero, oxidization of a film surface may be carried out. Thereby, the TeO2 film (10) may be formed on the surface, and an optical recording medium may be obtained which is extremely stable and has excellent adhesive properties between the substrates and between the layers.
Patent GB-8627049-D0 (GB)
Title: Cross-flow filtration
IPC: B01D29/46
Filed: 1986-03-12
Abstract: The filter has a spiral of, or parallel, spaced lengths of, double-ply material whose plies are seamed together along spaced, longitudinal seams to provide an array of side-by-side tubes. The filter support material is highly flexible and has a thickness not greater than 1 mm. Due to the tubular formation, the filter support has an uninterrupted filter zone of substantial area relative to the total area of the filter support; during filtration (when the filter support is under the pressure of the feed) the tube walls bulge out and the filter zone is restrained solely by tensile forces in the filter support itself. Substantial movement of the filter support is possible in the direction at right angles to its face when the pressures on either side of the filter support are equal. The filter support has many applications, but one application is when the filter is connected downstream of an aeration vessel with no intervening vessel, the concentrate outlet of the filter being connected to the aeration vessel for sludge return.

Abstract: A process for hydroshifting dimethyl ether is described which comprises passing a feed stream which includes dimethyl ether and steam to a hydroshifting reaction zone including an essentially alkali metal-free catalytic composition substantially composed of copper or nickel in elemental form. The process produces a hydroshifted product stream which is relatively rich in hydrogen, carbon monoxide, and carbon dioxide. The feed stream can be transported relatively easily in liquid form at comparatively low pressures. The hydroshifting reaction zone can include a hydrolysis reaction zone and a water-gas shift reaction zone. The hydrolyzed product and the water-gas shift product can be recovered to obtain hydrogen and carbon dioxide, respectively. Additionally, the hydroshifted product stream can be blended with an oxidizing stream and combusted to drive a turbine in order to generate mechanical energy.
