  • Patent number: 10421522
    Abstract: The invention relates to a cover device for at least sectional closing of an underwater opening in a hull of a watercraft, in particular an opening of a transverse channel of a thruster. According to the invention the cover device includes at least one variable-volume hollow chamber lip including at least one buoyancy body, and the at least one hollow chamber lip is shiftable into an expansion state or into a shrinkage state by supplying or removing a fluid, in particular air. As a result of the variable-volume or inflatable cover device a more reliable and simultaneously lower-maintenance operation of the cover device is given. In addition, the invention has a thruster, in particular a bow or stern-thruster, as subject matter.

  • Patent number: 10220923
    Abstract: A fin stabilizer for stabilizing watercraft includes a pivotable stabilizer fin and a receiving space for receiving the stabilizer fin. The stabilizer fin is shiftable from a retracted state in which the stabilizer fin is received in the receiving space to an extended state in which the stabilizer fin extends from the receiving space. Also at least one flexible cover element for at least partially covering an opening of the receiving space, through which opening the stabilizer fin enters and exits the receiving space during retracting and extending, respectively. The stabilizer fin does not contact the at least one cover element when shifting from the retracted state to the extended state.

  • Patent number: 9745031
    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.

  • Publication number: 20070023168
    Abstract: An apparatus (1) for cooling electronic components (2, 3, 4) comprises laminated plate-like parts that form a flow duct through which a liquid coolant can flow. At least one plate-like frame element (8) having cutouts (9, 10, 11) is arranged between the plate-like parts, wherein the cutouts (9, 10, 11) form sections of a coolant flow duct for selectively cooling electronic components mounted on mounting areas on one or more surfaces of the apparatus.

  • Publication number: 20060291165
    Abstract: An apparatus (1) for cooling electronic components comprises plate-shaped elements (2, 8), which enclose between them a cavity in the form of a flow channel, having connections (5, 6) for a liquid coolant flowing through the flow channel. One plate-shaped element comprises a highly thermally conductive, preferably metallic plate (8) connected in a thermally conductive manner to the electronic components.
