Abstract: A connecting element for insertion into the ends of at least two hollow sections of different cross-section, in particular in the case of a middle node (20) for an instrument panel transverse beam in automobile manufacture is such that a push-fit body (22) is shape-formed—by way of extrusion of a light weight alloy, plastic or other extrudable material—on a frame (30) with side walls (32) extending in the direction of insertion, whereby the push-fit body is of smaller cross-section than the frame and contains lengths of the frame walls (32). That frame (30) preferably surrounds the push-fit body (22) which in turn forms a corner (31) of the frame (22). In addition, the frame (30) may exhibit an integral frame bracket outside one frame side wall whereby the frame bracket walls are aligned with parallel frame walls.

Abstract: A container, in particular a container (30) with a tube-shaped wall (32), made of a light metal alloy for use as a reaction chamber in a process for manufacturing wafers, is such that the container wall (32) is made by way of extrusion or ring-rolling, and the container wall (32) is made from a metallic, aluminum-based material with a magnesium content between 1.2 and 2.0 wt. %; the elements Cu, Fe, Si are present in amounts less than 0.5 wt. %. This container wall (32) may also be shaped in one piece as container (30) with a base plate (42).

Abstract: A vehicle with a compartment, a ventilation channel on the ceiling or in a side wall of the compartment running in the longitudinal or transverse direction of the vehicle and a lighting facility with lighting elements is such that the ventilation channel features a reflector box with a channel base, featuring openings that are at least in part transparent to light or light-admitting openings, fitted facing the interior of the passenger compartment, and the lighting elements of the lighting facility are situated inside the ventilation channel. As a result of lighting facility being integrated in the ventilation channel, the amount of space required is less and the ventilation channel with integral lighting can be in the form of a pre-assembled unit.

Abstract: The invention relates to a Resin Transfer Moulding (RTM) process for manufacturing fiber-reinforced components (31) with at least one closed or undercut space (35). A two-part mould with a cavity is charged with reinforcing fibers and a shape-stable supporting core of wax that can be melted out of the cavity. The core is produced from a cast preform by means of at least one shape-forming step. A plastic matrix capable of flowing is injected into the cavity of the closed mould forming a shaped fiber-composite mass and hardened to give the fiber-reinforced component (31). The shape-stable fiber-reinforced component (31) is removed from the mould and subjected to tempering. During tempering the core is melted and drained off from the fiber-reinforced component—leaving behind a closed or undercut space (35)—and the molten core material is cast to provide a new preform (1).
