Patent number: 11939253Abstract: The invention relates to a method for shaping a glass pane (1), wherein the glass pane (1) is first heated and then bent until it has reached a shape that corresponds to a predefined target contour (ks), wherein exterior forces act on the glass pane (1) for the purpose of bending the glass pane (1). A change in a local curvature of the glass pane (1) over time is controlled such that the surface of the glass pane (1) simultaneously achieves the target contour at all points of the surface that do not remain static, by setting a temperature, and thus a viscosity, of the glass pane (1) so as not to be constant as a function of the location during the bending operation, and/or by suitably setting forces transferred by mounts (6) and/or pressure forces transferred by one or more pressure strips (3). The application furthermore relates to multiple glazed units produced by the method.Type: GrantFiled: July 31, 2019Date of Patent: March 26, 2024Assignee: Fraunhofer-Gesellschaft zur Förderung der angewandten Forschung e.V.Inventors: Matthias Gremmelspacher, Tobias Rist, Peter Gumbsch, Rainer Kubler, Adrian Baab

Publication number: 20220130620Abstract: The invention relates to a method of producing a plate arrangement comprising two plates (1, 2) which, at least in sections, have an intermediate space (4) located between them and a constant distance (d) to one another and/or are arranged parallel to one another and between which a fusible solder material (3, 3?) is arranged. The task of setting a defined distance between the plates as accurately as possible is solved according to the invention by creating a pressure difference between the intermediate space (4) between the plates and the outer space surrounding the plates in such a way that the pressure in the outer space is higher than in the intermediate space (4) and that the temperature of the solder material (3, 3?) is at least temporarily raised above its melting temperature during the existence of the pressure difference.Type: ApplicationFiled: January 31, 2020Publication date: April 28, 2022Inventors: Matthias Gremmelspacher, Rainer Kubler, Tobias Rist, Alexander Kott, Philipp Holler

Patent number: 10730781Abstract: The invention locally deforms a flat surface of a substrate made of glass or a glass ceramic by applying heat exclusively within a locally limited region via the flat surface by laser radiation, a gas flame, infrared radiation, microwaves or a plasma discharge directed towards the flat surface of the substrate to soften the substrate at least on the flat surface within the locally limited region; applies a force acting on the softened flat surface within the locally limited region which deforms the softened surface of the substrate within the locally limited region; cools the substrate to obtain a set deformed surface within the locally limited region; and applies heat exclusively within the locally limited region via the flat surface of the substrate to produce a temperature and viscosity gradient inside the substrate laterally and orthogonal to the flat surface within the locally limited region.Type: GrantFiled: April 27, 2017Date of Patent: August 4, 2020Assignee: FRAUNHOFER-GESELLSCHAFT ZUR FÖRDERUNG DER ANGEWANDTEN FORSCHUNG E.V.Inventors: Rainer Kübler, Peter Gumbsch, Tobias Rist, Matthias Gremmelspacher, Britta Lang

Publication number: 20190152828Abstract: The invention relates to a method for locally deforming a flat surface of a substrate made of glass or a glass-ceramic, and to an operating element that can be produced with the method. The method is characterised by the following method steps: applying heat exclusively within a locally limited region via the surface of the substrate by means of laser radiation, gas flame, infrared radiation, electrical microwaves or plasma discharge directed towards the surface of the substrate, in such a way that the substrate is softened at least on the surface within the locally limited region; applying a force acting on the softened surface within the locally limited region, such that the softened surface of the substrate is deformed within the region; and cooling the substrate to obtain a surface that is deformed and set within the local region.Type: ApplicationFiled: April 27, 2017Publication date: May 23, 2019Applicant: Fraunhofer-Gesellschaft zur Förderung der angewandten Forschung e.V.Inventors: Rainer KÜBLER, Peter GUMBSCH, Tobias RIST, Matthias GREMMELSPACHER, Britta LANG

Patent number: 8181844Abstract: The invention is a method for permanent connection of two components by soldering employing a glass or metal solder as the solder material. A layer system providing adhesion is applied to both components, between which the solder material is introduced. the layer system is heated to a soldering temperature characteristic for the solder material and results in a permanent solder connection between both components after cooling. The layer system providing adhesion has an adhesive layer applicable directly to the component and a solderable layer. The adhesive layer, if a glass solder is used, contains oxidic, carbidic, or nitridic components or mixed compounds thereof and, if a metal solder is used, the adhesive layer contains carbidic or nitridic components or mixed compounds thereof.Type: GrantFiled: February 24, 2011Date of Patent: May 22, 2012Assignee: Fraunhofer Gesellschaft zur Forderung der Angewandten Forschung e.V.Inventors: Jan Hagen, Thorsten Faber, Rainer Kubler, Gunter Kleer

Patent number: 5187424Abstract: A process for determining the state of a battery by carrying out in a cycle, starting from a specific charging state of the battery, a charging operation and a discharging operation, each with a specific current, the cycle being terminated when the specific charging state is reached again, and the state of the battery being deduced from the difference between the time periods required for the charging operation and the discharging operation. Alternatively, from a specific charging state of the battery a discharge can be carried out, in order to determine the available capacity from the extracted charge.Type: GrantFiled: December 4, 1991Date of Patent: February 16, 1993Assignee: Mercedes-Benz AGInventors: Klemens Benz, Rainer Kubler
