Abstract: The present disclosure relates to a protective structure for the protection against moving masses, namely avalanches, rockfalls, mudslides and loggings, having a plurality of ballast-filled wall elements, which are arranged in a manner adjacent to each other and spaced apart on a bearing surface, and having a respective connection arrangement between two adjacent wall elements which connects the two adjacent wall elements and enables relative movement between the two wall elements. The wall elements are movable in relation to the bearing surface and in relation to each other by the moving mass, namely avalanche, rockfall, mudslide or logging, for dissipative energy conversion.

Abstract: The present disclosure relates to a protective structure having a plurality of supports arranged spaced apart from each other; having a trapping device which is guided on the supports via at least one support cable arrangement; and having a ground anchorage for free ends of the at least one support cable arrangement. The ground anchorage is designed as a deadman anchorage.

Abstract: The present disclosure relates to a rockfall barrier for installation between an uphill side and a downhill side of a hill slope, with at least two guide devices for a net comprising an upper edge and a lower edge, and with an upper load-bearing rope, which guides the upper edge on the guide devices At least one middle rope is provided, which extends from an upper end point fixed to the upper load-bearing rope to a lower end point fixable at the hill slope.

Abstract: A protective construction, such as a fence for a race track, may include a device for energy dissipation, e.g., in line with a guy wire. In some examples, the energy dissipation device may have a braking profile and a cutting unit having at least one blade that can be pulled through the braking profile along its longitudinal axis.

Abstract: A metering device (4, 82, 96) for metering a fluid includes a common supply line (6) and multiple discharge lines (20). To improve the metering process, the metering device (4, 82, 96) includes multiple delivery devices (18) each having a cavity (24) for receiving the fluid and a piston (26) for displacing the fluid, wherein each of the multiple delivery devices (18) is connected on the inlet side to the common supply line (6) and is connected on the outlet side to one of the multiple discharge lines (20).

Abstract: The present invention relates to a device and a method for energy dissipation with a deformable, longitudinally extending material strip which comprises a longitudinal axis and is installed into a cable which can be subjected to tension; and with a deformation device which is also installed into the cable and cooperates with the material strip, characterized in that the material strip, upon application of a tension force to the cable along its longitudinal axis, can be guided in a straight line through the deformation device and in so doing can be deformed.

Abstract: A rockfall protection system may include a plurality of supports that each have a support head, along with a catch net, an upper support cable guiding an upper edge of the catch net at the support heads, and an upper central cable and a lower central cable guiding the catch net in a central support area of the supports. The lower central cable may be tensioned using side anchors provided with at least one braking element. The system may also include a lower support cable guiding a lower edge of the catch net and being guided together with the lower edge of the catch net on the downhill side of and separated from the supports. The braking element may be connected to the side anchor and to the central cable by a cable loop. The side anchor and central cable may be connected via a predetermined breaking point.
