  • Publication number: 20240173803
    Abstract: Disclosed are a method and a device for cutting a foil which contains at least one layer of metal. The laser for cutting the foil is controlled such that pulsed laser radiation cuts through at least one layer of metal of the foil such that the metal of the foil is mostly sublimated and scarcely melts. The resulting laser-cut foil does not have, or has very small sized, bead structures and/or metal splashes of solidified metal. When the foil is used in a battery, the electric performance and durability of the battery are greater and the risk of a short circuit is lower.

  • Patent number: 7525664
    Abstract: The invention relates to a device and a method for the optical detection of substances contained in exhaust gases of chemical processes, wherein exhaust gases are conducted all the way through a channel element that forms an optical measuring section; at the channel element there are two flanges, closed off to the ambient area, and at least one window element through which electromagnetic radiation for the optical detection can be directed from a radiation source to a optical detector through the channel element; a purge gas is fed through the flanges into the channel element, whereby with a purge gas led into one of the flanges a closed laminar purge gas flow is to be formed in the bottom area of the interior of the channel element.
