摘要： A current collecting device for a fuel cell stack (1) comprising a number of stack-forming fuel cell plates (2) between opposite end plates (3, 4), each end plate being connected to a current collector (5 resp. 6). The current collector (5 resp. 6) comprises a plate (15) which, with one surface (16), is pressed against the associated end plate (3 resp. 4), the surface (16) being provided with a number of grooves (17) extending across a substantial part of the area of the plate (15) and receiving respective electric line wires (19) collected in at least one line bundle (7 resp. 8), the wires (19) in the grooves (17) being covered by a layer (21) of noble metal projecting somewhat above the surface of the plate (15) and forming an electrical connection between the line wires (19) and the end plate (3 resp. 4) in question.

摘要： A method for carrying out marine seismic surveys by using a seismic cable comprising a cable (2) and sensors (4) for detecting seismic signals, said sensors (4) comprising geophone units (6) which rest in the measuring positions on the ocean floor during measurement of the seismic signals and where the seismic cable is moved along the seabed to its next measuring position between the measurements. Before measurements are taken the geophone units (6) are subjected to vibrations so that the geophone units (6) assume a position in good contact with the ocean floor (3) and dig themselves down into it. The invention also comprises a seismic cable for carrying out the method. Here the geophone units (6) are loosely attached within the frame structure (7) and are equipped with at least one vibrator (14) which is powered via the cable (2).

摘要： A system for use in offshore oil and gas production from production wells on the sea bed, comprising a submerged buoy (1) having an outer buoyancy member (13) which is arranged for introduction and releasable fastening in a submerged, downwardly open receiving space (9) in a vessel (8), and a central member (14) which is rotatably mounted in the outer member (13) and is anchored to the sea bed and is connected to at least one transfer line (17) extending from a respective production well up to the buoy, a shaft (10) extending between the receiving space (9) and the deck (11) of the vessel (8). A swivel unit (15) comprising inner and outer mutually rotatable swivel member (20', 20') is arranged at deck level, and with the inner swivel member is rigidly connected to a holding cylinder (30) extending downwards through the shaft (10) and with its lower end being non-rotatably connected to the central member (14) of the buoy (1). The central member (14) of the buoy is provided with lead-through passages (16) for the topical number of transfer lines (17), so that these can be pulled up through the buoy and via the holding cylinder (30) up to the swivel unit (15), these lines (17) at their upper ends being arranged for connection with associated conduit connections (22) which are connected via the swivel unit (15) to a tube system (24) on the vessel (8).

摘要： A reactor for conducting a continuous multi-phase catalytic reaction such as the conversion of syngas to higher hydrocarbon fuels. Gaseous reactants are introduced via a gas-permeable plate into a slurry which includes the product and a finely divided catalyst. The liquid product is separated from the remainder of the slurry by means of a filter unit including a filter member. A pressure differential is established across the filter member by means of a constant level device within the filter unit which maintains a level of filtrate within the filter unit below the level of the slurry. The slurry is maintained in a constant state of agitation by the introduction of the gaseous components as a steam of bubbles. Fluctuations in the pressure differential across the filter member prevent the filter member from clogging and the gas spaces above the filtrate and the slurry are in communication.

摘要： The invention relates to a method as well as equipment for smoothing out occurrences of long liquid plugs, so-called slugs, in fluid flows which comprise more than one phase. The invention is particularly intended for use in transport arrangements for oil and gas, namely multi-phase arrangements for the transport of mixtures of oil and gas. The equipment which is used (termed slug catcher) comprises, amongst other things, a vortex chamber (1) and an overlying pressure tank (2) which temporarily stores oil slugs and portions them out back into the gas flow so that the load on the transport equipment is smoothen out.
