Abstract:
The invention relates to a system for producing and dispensing pressurized hydrogen comprising: - a hydrogen generator (1), in particular an electrolyser, - a hydraulic drive (16), - two or more hydrogen storage tanks (10a, 10b, 10c), and - a hydrogen dispensing unit (50), - wherein each of the hydrogen storage tanks (10a, 10b, 10c) is capable of discharging hydrogen at a constant pressure by movement of an internal piston (11a, 11b, 11c), - wherein at least one (10a) of the hydrogen storage tanks (10a, 10b, 10c) is arranged to act as compressor by actuation of the internal piston (11a) by means of the hydraulic drive (16), and - wherein at least one (10a) of the hydrogen storage tanks (10a, 10b, 10c) is arranged to act as a constant pressure tank for storing and discharging hydrogen at a constant pressure.
Abstract:
The invention relates to a binder material activating device (10) to activate a binder material (18) on a fibrous substrate (14), the binder material activating device (10) comprising a heat exposing device (20) to expose the fibrous substrate (14) with the binder material (18) to heat. The heat exposing device (20) comprises a non- focused light source (22) to provide a non-focused light beam (12) and an optics device (28) to be arranged in between the fibrous substrate (14) to be exposed to heat and the light source (22) to focus the non-focused light beam (12) onto the fibrous substrate (14). Further, the invention relates to a preforming device (40) comprising the binder material activating device (10).
Abstract:
The present invention relates particularly to a direct current switching device comprising at least one switching unit which can be mounted between two terminals. The device can further comprise at least one control unit for controlling the switching unit. The switching unit can comprise at least a first and a second semiconductor switching element, which can be mounted in parallel to each other, and the first switching element can be a high-voltage switching element and the second switching element can be a switching element with little power loss. The switching unit can be controlled by the control unit such that when the switching unit is switched off, first the second switching element can be switched to nonconductive and then the first switching element can be switched to nonconductive, and when the switching unit is switched on, first the first switching element can be switched to conductive and then the second switching element can be switched to conductive.
Abstract:
The invention relates to changes to wing profiles. In order to provide an aerodynamic structure that can be adapted and changed in many ways in terms of the wing profile, an aerodynamic structure (10) for a wing device or control surface device of an aircraft according to the invention has a supporting structure (12) and an outer skin (14). The supporting structure has a stationary spar (16) in the longitudinal direction, which spar extends from a root region to an outer end region. The supporting structure also has a plurality of adaptive framework segments (18) in the transverse direction, which each consist of a plurality of triangular compartments (20), which are arranged next to each other and are formed by control elements (22) of stationary length and control elements (24) of adjustable length. The framework segments are connected to the stationary spar. At least some of the triangular compartments have one of the adjustable control elements, at least on one side, such that the framework segments are adjustable in shape. The outer skin is fastened to the framework segments. An outer contour (26) of the aerodynamic structure can be changed at least in the transverse direction by adjusting the shape of the frameworks.
