  • Patent number: 8465256
    Abstract: Wind power plant rotor comprising one or more rotor blades and stiffening elements to stiffen the rotor, where the rotor blades are arranged such that they can turn around their longitudinal axes relative to corresponding rotor stiffening elements. Each rotor blade may comprise at least two rotor blade parts where the outer rotor blade part may be turnably arranged relative to the inner rotor blade part. The solution facilitates use of longer or slimmer rotor blades while strength and stiffness increase. The fatigue forces are thereby reduced while the corresponding tower structure can be made stiffer and lighter. Manufacturing and transport costs are reduced. Further, the stiffening elements may be formed with an aerodynamic outer cross section as for example a drop profile or wing profile in order to reduce air drag and audible noise.

  • Patent number: 6581975
    Abstract: System for loading and unloading of cold media, for example LNG or LPG, to or from a vessel, through pipes (1) connected with ball joints, where the pipes are insulated, and when each ball joint's inside part (4) has an inside pipe (3) which is sealed against the inside part (4) substantially over the letter extent, and which thereby forms an inside annulus (6) which can be evacuated, and that each ball joint's outside part (10) is surrounded by an outside annulus (9) which also may be evacuated.

  • Patent number: 5456198
    Abstract: In a hull the skin plate is built up as a composite member with an outer skin, a core and an inner skin. The skin plate is placed on the framework which includes longitudinal stiffeners. The inner skin is constructed as a diaphragm element relative to the external water pressure, while the core is made as a pressure-absorbing element and the outer skin is constructed primarily as a bending stressed element. The inner skin as a diaphragm will take tensile stress and be protected against outer local stresses. The material in the core can be chosen without major requirements to be able to tolerate shearing stress. The outer skin can be dimensioned and made primarily to take local shock loads.
