Abstract: The invention relates to a rope-tensioning device for rope networks. The object of the invention is to develop a tensioning device, in particular for rope networks, with a tensioning mechanism which is arranged outside of areas accessible to players and which is covered completely or to a significant part. Maintenance of the tensioning device and operation of the tensioning mechanism should not be limited. The rope tensioning device for rope networks of the invention is characterized by a rope tensioner for rope networks arranged to the greatest extent possible inside a short section of pipe (pipe section). Advantageously, a pipe element with the rope tensioner can be combined with different framework elements, such as support masts, center masts, framework nodes and mounting devices located close to the ground.

Abstract: A generator including a double-chamber lock comprising two tapered or vertical chambers lined with ceramics or plastics, as a charging device, at least one tubular shaft furnace comprising a water-cooled double jacket of steel, a double-walled, water-cooled inlet nozzle of copper for a gasification mixture, arranged centrally in the tubular shaft furnace above the base, a dry dust-removing device, and optionally a desulfurising device. The double-chamber lock has a mechanism which causes one of the chambers to open when the lower chamber of the double-chamber lock is flushed with inert gas after charging/opening operations, and the inlet nozzle constitutes the mixing member for the constituents of the gasification mixture, the inlet nozzle has a radius of curvature of the surface of the cylindrical portion of the nozzle which continuously becomes smaller to the outlet opening, and the direction of flow of the gases leaving the inlet nozzle is directed upwards.

Abstract: Known climbing frames having a support frame, in which a rope net is rigged, are not very attractive as individual playing devices, as no considerable 3-dimensional net volume is provided and on the other hand as the device cannot be combined by modular elements to larger units. According to the present embodiment, the support frame consists of at least one pentagonal frame element, wherein a separate rope net is rigged within each frame element. The frame elements can thus be assembled in a modular manner to form complex 3-dimensional structures.
