Abstract: The present disclosure relates to a method of metadata enrichment using an enrichment comprising multiple steps. The method comprises: determining for an input data asset a metadata value descriptive of the input data asset. Characteristics of the metadata value of the input data asset may be determined. At least one informativeness score of the metadata value of the input data asset may be computed using the determined characteristics. An execution of the enrichment step may be skipped in case an input characteristic of the enrichment step is not part of the determined characteristics. In case the input characteristic of the enrichment step is part of the determined characteristics, the enrichment step may be adapted and executed or the enrichment step may be executed without adaptation. Labels resulting from the executed enrichment steps may be combined for providing one or more labels of the data asset.

Abstract: In order to separate tin can bodies carried by a first conveyor belt at a high speed, a second conveyor belt is taken close to the first conveyor belt and individual bodies are transferred from the first conveyor belt to the second conveyor belt. It is thus possible to separate a sequence of tin bodies into two sequences, thus facilitating further processing. The process can also be reversed to form a single sequence from two sequences.

Abstract: Sheet metal edges to be welded are preheated prior to welding. At a given welding speed, this results in a smaller temperature gradient in the material to be welded. Consequently the welding speed can be increased, or material which would otherwise provide poor weld quality can be welded at a high temperature gradient. The preheating is carried out for example by high-frequency excitation of the material to be welded.

Abstract: The measurement of the voltage over the welding point in order to supervise the welding quality takes place by means of voltage taps on the wire electrodes. As a result, the additional parasitic resistances during measurement by means of conventional voltage taps on the roller head or the roller head mounting are completely eliminated, which improves the measuring accuracy.
