Abstract: A test device for determining the particle load of pressurized hydrogen includes a housing (2), with an inlet (4) and an outlet (8) for the inflow or outflow of hydrogen, respectively. A sampling chamber (52) has a filter holder (44) for a test filter (58). A sample amount of hydrogen can flow through the test filter during a test procedure. After the test procedure has been completed, the test filter can be removed from the sampling chamber (52) for evaluating the deposition of particles. A venting device (64, 70) for reducing the pressure in the sampling chamber (52) is arranged inside the housing (2) and discharges any remaining hydrogen, at least partially, in the direction of the inlet (4) of the test device after the hydrogen has stopped flowing from the testing device.

Abstract: A device for fastening and/or guiding strand-shaped elements in wind turbines has a retaining body (1; 101) attachable to a carrier structure and a strand-receiving space (9; 109) as a bearing for at least one strand element introduced into it via an opening (29; 111) located on its outer side.

Abstract: A fixing device has a lug strip (10). At least one end (12) of the lug strip (10) is bent to form a fixing loop (14).

Both fixing pieces (26) are diametrically opposed to each other on the respective retainers (22, 24), and have fixing surfaces. The functional piece (28, 30) runs at least partly perpendicular to the common longitudinal axis of the fixing piece (26). Each fixing surface is provided with a convex curvature. A fixing device with few components, which can be easily finished to give a lug at the site of assembly without any additions is achieved. The convex curvature of the functional piece (28, 30) runs perpendicular to the common longitudinal axis of the fixing pieces (26) essentially along a semi-circle.
