  • METHOD FOR CONTACTING AN ELECTRICALLY CONDUCTIVE PAPER STRUCTURE, COMPOSITE BODY AND USE
    Publication number: 20240365441
    Abstract: The invention relates to a composite body comprising a support plate having recesses, the support plate having an upper main surface and a lower main surface and an electrically conductive paper structure adjoining the upper main surface of the support plate, wherein the electrically conductive paper structure has at least one conductor track facing the upper main surface of the support plate, wherein conductor elements are introduced into the recesses of the support plate in such a way that the conductor elements are flush with the upper main surface of the support plate, wherein the conductor elements are in electrical contact with the at least one conductor track of the electrically conductive paper structure and wherein the conductor elements are contactable with a current source from the lower main surface of the support plate.

  • Composite glass with an intermediate film that changes colour depending on the viewing angle
    Patent number: 11745474
    Abstract: A composite glass comprises two glass and/or plastic plates and an intermediate foil arranged between the glass and/or plastic plates. The composite glass, due to the intermediate foil, is configured differently in a side-dependent manner, by appearing to a viewer more transparent from an inner side than from an outer side. The composite glass, due to the intermediate foil, appears to the viewer different in a viewing angle-dependent manner from the outer side.
