Abstract: There is described a fiber-reinforced material composed of a sheetlike textile material and a thermoset resin with a fiber content of from 30 to 70% by weight, at least 30% of the fiber being synthetic fiber. The thermoset resin is preferably a phenolic resin which contains up to 25% by weight of a fluoropolymer. The sheetlike textile material is preferably 100% synthetic fiber, in particular polyacrylonitrile fiber. There are also described a prepeg formed from the textile material and the thermosetting resin and the process for producing these articles and the use of the material for producing construction elements, in particular for hydraulic systems, by application of mechanical shaping processes.

Abstract: An airbag cover in a dashboard, a steering wheel hub cover, or door panel with at least one predetermined breaking line whose shape is substantially determined by a line-shaped weakened portion. The line-shaped weakened portion is a perforation line extending until approximately below the surface visible to the vehicle passengers. This perforation line is advantageously a curve alternating around the predetermined breaking line and is at least similar in shape to the structure of the visible surface.

Abstract: Thick matter and solids are conveyed together and substantially continuously through a conveyor pipeline. The thick matter is forced by a conveyor piston driven by a piston pump from a feed container into a conveyer cylinder. A forward face of the piston has a cutting crown with a cutting edge cooperating with an annular cutting ring to cut off solids projecting beyond an inlet in the conveyer pipeline.

Abstract: The invention relates to a conveyor for thick substances containing a great deal of solids and having a conveyor pipe (20) which can be filled with the thick substances under pressure and at least one injection point (22, 24) opening into the conveyor pipe (20) to supply a lubricant (83) to the region (84) between the pipe wall and the surface of a plug flow of thick substance (82) being formed in the conveyor pipe (20). In order to center the plug flow (82) inside the conveyor pipe (20) and provide a stable layer of lubricant (83), the invention proposes that the conveyor pipe (20) have at least one annular waist at a distance from and downstream of the injection point (22, 24) formed by a collar or shoulder-like projection (62') inside the conveyor pipe (20).

Abstract: The ski described is characterized by the use of a selected fiber reinforced material comprising a sheetlike textile material and a thermoset resin, the fiber content being 30-70% by weight and the fiber being not less than 30% by weight synthetic. This material is notable for high flexibility and high restoring forces and confers excellent properties on the ski, for example good vibration damping.
