Abstract: Floatable, torus-segment-like pontoon for a torus-like floating body constructed from a plurality of such pontoons, with a torus eye containing the torus axis of rotation. The pontoon comprises connecting means on substantially flat side surfaces, which are designed in such a way that adjacent pontoons can be joined in a positive-fitting manner in the axial direction; Receiving areas on the radially inner pontoon surfaces for receiving a component in the torus eye; Retaining means arranged on the radially outer pontoon surfaces for holding adjacent pontoons together in the torus circumferential direction and in the radial direction; and connecting means configured on one of the side surfaces as at least one groove extending in the radial direction and on the other side surface as at least one opposite, substantially complementary tongue opposite to the groove. Said pontoon made of plastic and produced by rotational melting, extrusion blow moulding or RIM process.

Abstract: Electronic module for the mounting of electronic components comprising a housing that is bounded in a longitudinal direction by two end faces, each with an opening. The housing can be fitted via the openings with at least one first circuit board, equipped with electronic components, and with at least one second circuit board, equipped with plug and/or clamp connectors. On an inner side of one housing wall, the housing comprises at least one dome, configured in a longitudinal direction, on which the at least one first circuit board can be attached essentially transversely to the longitudinal direction. At two opposite-facing inner sides and/or two opposite-facing domes, the housing furthermore comprises a retaining groove in which to insert at least one second circuit board in a longitudinal direction.

Abstract: Device for the reversible transfer of linear motion into rotational motion and for the conversion of rotational motion into electrical energy and vice versa. The device comprises a central rail and a support element which surrounds the central rail or is being surrounded by the central rail, the support element being positioned so as to be capable of performing a linear motion relative to the central rail in the longitudinal direction of the central rail. A number of rolling bodies which are in contact with the central rail are rotationally mounted in the support element. The rolling bodies rotate during the linear motion of the support element relative to the central rail in conjunction with the central rail. The linear motion is also connected to the drive or output of an electric machine.
