Publication number: 20140320992Abstract: The invention relates to a mirror comprising a reflective surface formed from a composite of a reflective film and a substrate, wherein the reflective film is disposed on the substrate and comprises at least one polymer layer and a metal layer disposed underneath the at least one polymer layer. It is the requirement of the invention to propose a mirror which can be manufactured in a simple way and at the same time comprises an improved corrosion behaviour. According to a first teaching of the present invention the stated requirement is met in that a sealing seam is provided for corrosion protection at least in certain areas, the sealing seam being formed by bonding the polymer layer to the substrate in a material-locking manner, wherein the metal layer is interrupted in the area of the sealing seam.Type: ApplicationFiled: July 10, 2014Publication date: October 30, 2014Applicant: Hydro Aluminium Rolled Products GmbHInventors: Volker Denkmann, Wilhelm Schenkel, Andreas Siemen, Ulrich Hampel, Sandra Eberhard

Patent number: 5098530Abstract: A carbon electrode surrounded by a protective globe in a fusion refining electrolysis process. The protective globe is self-supporting, gastight and thermally stable. The protective globe is spaced from the carbon electrode by a predetermined distance. Also, there is a predetermined distance between an end of the carbon electrode to be immersed in a melting bath and an open end of the protective globe through which projects the carbon electrode. A preheating process requires the electrode to be initially preheated over the melting bath, then its exposed end is immesered into the melting bath while not immersing the protective globe, and finally immersing both the electrode and the protective globe.Type: GrantFiled: November 9, 1989Date of Patent: March 24, 1992Assignee: Verenigte Aluminium-Werke AGInventors: Rainer Sudholter, Ulrich Hampel
