    摘要: 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). A bore (72) passing radially through the pipe wall for the connection of a lubricant injection line (76) may be provided in the flow shadow of the waist (62'), and at least one further waist (79) is provided downstream at a distance from the injection drilling (72).

    摘要: 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.
