Abstract: A line connector having a connector piece with at least one junction portion for junction connection to a media line or to an assembly, a transitional portion contiguous to the junction portion, and a flow duct. In at least the region of the transitional portion, an electrical heating element for the media line is provided in an arrangement at least partially surrounding the flow duct. The connector piece, together with the heating element, is surrounded by an outer cladding. At least one of the junction portions is designed as a hollow, cylindrical receptacle for directly plugging in the end of the media line, the media line being capable of being fastened in a materially integral manner. The junction portion including, at least in regions, a material transparent to laser beams in such a way that the media line can be fastened by way of laser welding.

Abstract: The present invention relates to a line connector for media lines, consisting of a connector piece with at least one junction portion for junction connection to a media line or to an assembly and with a transitional portion contiguous to the junction portion and having a flow duct. In this case, at least in the region of the transitional portion, electrical heating means are provided in an arrangement at least partially surrounding the flow duct. Furthermore, the invention relates to a ready-made media line consisting of a pipeline with a heating conductor arranged on the circumference and with a heatable line connector fastened at least to one pipeline end of the media line.

Abstract: A sound absorber comprises a bottom portion and a structure portion joined to the bottom portion and closed off from outside, the structure portion having chamber walls forming hollow chambers, the hollow chambers being formed like small boxes or cups. Between the bottom portion and the structure portion, in the region of the hollow chambers, welds are formed between parts of the chamber walls of the structure portion and the bottom portion such that the chamber walls are in part welded to the bottom portion. In part the chamber walls project towards the bottom portion without being welded thereto such that an air gap is formed between an end of these chamber walls and the bottom portion, the hollow chambers forming a common air space enclosed between the structure portion and the bottom portion.
