Patent number: 11396471Abstract: A method for the production of glass or glass ceramic elements from flat glass or glass ceramic parts is provided where the edges of the glass or glass ceramic elements are treated by a combination of two processes. The flat glass or glass ceramic element with an edge surface connecting the two side surfaces is produced. The edge surface has at least one first elongated, strip-shaped edge region and at least one second elongated strip-shaped edge region, which are formed by a ground edge. The edge regions extend in the longitudinal direction along the edge surface and along the side surfaces. The first edge region has elongated parallel filamentary damages that are parallel and adjacent to one another and, in particular, spaced apart equidistantly, in the longitudinal direction thereof extending transversely to the side surfaces and along the surface of the first edge region.Type: GrantFiled: September 15, 2020Date of Patent: July 26, 2022Assignee: SCHOTT AGInventors: Volker Plapper, Fabian Wagner, Andreas Ortner, Albrecht Seidl, Frank-Thomas Lentes

Publication number: 20220081343Abstract: A method is provided that includes providing a glass sheet of a thickness of at most 300 ?m and irradiating the glass sheet with a pulsed laser beam. The laser beam has a light intensity inside the glass sheet leaves a filamentary damage along its path through the glass sheet. The laser beam and the glass sheet are moved relative to each other so that due to the pulses of the laser beam filamentary damages are inserted next to one another along a path running on the glass sheet. During the insertion of the filamentary damages, a tensile stress is applied on the glass at the filamentary damages and in the direction transverse to the path of the adjacent filamentary damages so that the glass sheet separates along the path during insertion of the filamentary damages.Type: ApplicationFiled: September 15, 2021Publication date: March 17, 2022Applicant: SCHOTT AGInventors: Michael Waschbüsch, Volker Plapper, Klaus-Peter Kurek, Ulrich Engelhardt

Patent number: 9999696Abstract: The invention relates to a system for treating gases and/or liquids with radiation or for detecting radiation in gases and/or liquids, including at least one optical system and a reactor. The reactor has a hollow body shape which includes lateral surfaces, connecting parts, and an inner chamber which may be open to the front and rear sides, through which a medium flows or in which the medium is present. The reactor is designed, at least partially, in the form of a radiation reflector and is divided into first and second functional areas. This enables a particularly homogeneous radiation distribution in the inner chamber of the reactor, which increases the efficiency of the treatment or detection. Also, due to this arrangement, the system is more compact.Type: GrantFiled: May 15, 2015Date of Patent: June 19, 2018Assignee: Schott AGInventors: Jörg Blechschmidt, Michael Kluge, Volker Plapper
