  • Patent number: 11939253
    Abstract: 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.

  • Patent number: 10974958
    Abstract: A method for producing micromechanical components is provided. A liquid starting material which can be cured by means of irradiation is applied onto a substrate. A partial volume of the starting material is cured by means of a local irradiation process using a first radiation source in order to produce at least one three-dimensional structure. The three-dimensional structure delimits at least one closed cavity in which at least one part of the liquid starting material is enclosed. Alternatively or in addition, a micromechanical component is provided that contains a liquid starting material, which is partly cured by means of irradiation, and at least one cavity in which the liquid starting material is enclosed.

  • Patent number: 10730781
    Abstract: 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.

  • Publication number: 20190152828
    Abstract: 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.

  • Publication number: 20070239809
    Abstract: The invention relates to a Method for calculating a local extremum, preferably a local minimum, of a multidimensional function E(x1, x2, . . . , xn) which is interpretable as a function of potential energy with spatial coordinates (x1, x2, . . . , xn), using an iteration process based on a molecular dynamics based quenching method comprising the following steps: a) Calculating a trajectory X(ti) at discrete times ti=?i?ti starting from an assigned initial coordinate X(0) on basis of a gradient fk=?E/?xk with k=1, . . . ,n and a time derivatives of the coordinates vk=dxk/dt using fxk=mxk dvxk/dt in which mxk represent masses at the spatial coordinates and vxk=dxk/dt represents velocity b) Performing a molecular dynamics based quenching method for analysing said function E(x1, x2, . . .
