Abstract: A fin stabilizer for stabilizing a watercraft against rolling movements includes a main fin configured to be pivoted by a watercraft-side fin drive, a tail fin, and an elastically deformable connection between the main fin and the tail fin, the elastically deformable connection being configured to flex whenever a water force acting on the tail fin is greater than a predetermined amount.

Abstract: A complex, three-dimensional lattice made of previously impregnated fiber strands is laid over nodes, thus forming the main body of the component to be produced. The composite wound rod structure, comprising a skeleton of ribs that are formed of impregnated fiber strands in a continuous winding and laying process, is characterized in that the ribs are solid ribs, or lattice structure ribs prefabricated from fiber strands, which contain nodes, over which the impregnated fiber strands are alternately, and incrementally, placed diagonally, horizontally and vertically, until the desired strand thickness has been reached, and the wound rod structure can be segmented as needed. The solid ribs are made of fiber composites, aluminum, or other lightweight materials.

Abstract: The invention can be used for the pressurized storage of gases. The aim of the invention is to provide a pressurized container consisting of fibre-reinforced plastic with flat or practically flat lids. To achieve this, wound axially aligned reinforcement structures run through the interior of the body and absorb the major part of the required forces on their plane of alignment. The invention is characterized in that fibre strands are distributed uniformly over the cross-sectional surface of the cylindrical pressurized container, are aligned axially and fixed to flat or practically flat lids. In one advantageous embodiment of the invention, a container is formed by the spiral winding of an essentially unidirectional fibre-layer, which is thicker at its edges. Reinforcement layers, which are arranged in a circumferential direction and exert a radial action, cover the reinforcement strands or the spirally wound unidirectional fibre-layer, said layers forming the casing of the pressurized container.
