20090084493 | Method of manufacturing an article of fiber-reinforced composite material - A method and a tool component for forming in an article of fiber-reinforced composite material at least one locally placed, sharply curved portion. A separate, substantially rigid pressure-transferring element configured with a profile corresponding to the at least one curved portion is placed over the laminate at the location of the at least one locally placed, sharply curved portion of the mold surface. A flexible membrane placed over the laminate and over outer, separated surfaces of the pressure-transferring element is evacuated to depress the laminate to fully conform to the shape of the mold surface. | 04-02-2009 |
20090102092 | METHOD FOR MANUFACTURING BEAMS OF FIBER-REINFORCED COMPOSITE MATERIAL - A method for manufacturing a hollow load-bearing beam structure of fiber-reinforced composite material. The method includes preparing a first lay-up of a first plurality of layers, and a second lay-up of a second plurality of layers. The first and second lay-ups are positioned on different sides of a mandrel and formed to a beam structure by bending the lay-ups against the mandrel, such that the side edges of the respective layers of the first and second lay-ups are arranged as offset butt joints in the circumferential direction of the formed beam structure. | 04-23-2009 |
20090107619 | Method and tool for forming an elongate, hollow article of a fiber-reinforced composite material - In a method and a tool for forming an elongate, hollow article of a fiber-reinforced composite material one end of an article laminate applied to a tool bar is placed in engagement with or is supported by an anvil of the tool so as to control the direction of longitudinal movement of the cured article relative to the tool bar during the cooling and dismantling phase. | 04-30-2009 |
20110248431 | THERMOFORMING APPARATUS - A thermoforming apparatus for forming a blank into a composite article. The thermoforming apparatus includes a forming tool. A forming member forms the blank over the forming tool. A first chamber is arranged for containing the blank. A second chamber is separated from the first chamber by the forming member. A first air circulator is configured to circulate air in the first chamber for achieving a heat distribution to the blank. The first air circulator includes a controllable valve member. The apparatus also includes a second air circulator. A method for forming a blank during circulation of air in a first chamber. | 10-13-2011 |
20110315300 | METHOD OF ATTACHING ELEMENTS BY BONDING - A method of attaching a first portion and a second portion to each other. An adhesive is exposed to a low temperature in order to obtain a non-tacky adhesive. The non-tacky adhesive is arranged between the two portions. The adhesive is cured. Use of adhesive according to the method. | 12-29-2011 |

20090114473 | SHEAR WAVE GENERATOR - A shear wave generator for use subsea, including an excitation unit that is fastened to a top plate; a skirt, the upper end of which is fastened sealingly to the top plate and extending downward to an open lower end of the skirt, such that the top plate and skirt form a closed space by lowering to the seabed; and a pump arranged with fluid communication between the space and the surroundings, such that by pumping water out of the space, an underpressure is formed acting to suck the shear wave generator fixedly to and partly into the seabed, and by pumping water into the space, an overpressure is formed acting to lift the shear wave generator up from the seabed. The shear wave generator is distinguished in that the skirt is formed with a larger outer diameter or width at its upper end than at its lower end. | 05-07-2009 |
20090278541 | Electromagnetic Method on Shallow Water Using a Controlled Source - A method for analysing acquired electromagnetic measurements (R) made at or in a sea ( | 11-12-2009 |
20110242935 | METHOD OF PROVIDING SEISMIC DATA - A method of providing seismic data (such as marine seismic data). A seismic source is actuated at a plurality of source locations (S | 10-06-2011 |
20140334256 | APPARATUS FOR MARINE SEISMIC SURVEY - An apparatus for conducting a marine seismic survey is disclosed. The apparatus includes a plurality of sensors configured to measure water pressure, a horizontal derivative of the pressure in two orthogonal directions, vertical particle velocity or acceleration of the water, and a horizontal derivative of the vertical particle velocity or acceleration in two orthogonal directions. | 11-13-2014 |
