20100296716 | TOMOGRAMS FOR IMPLANT PLANNING - Method for creating and presenting layer images that are generated from a set of volume data, whereby the volume data are recorded with a tomographic recording device, for example with a “cone beam CT” device, and show the jaw area of a patient, whereby planning data are assigned to the volume data, and said planning data describe the position of an implant that is to be inserted into the jaw and that has an implant axis, whereby a coordinate system that is adapted to a panoramic curve or a panoramic surface is defined that is formed by the vectors u, v, and w that are orthogonal to one another, whereby for the creation and presentation of a layer image, a representational plane is selected that intersects an implant that is described by the planning data, whereby in a first case, the v vector is orthogonal to the panoramic surface and/or the panoramic curve, and the implant axis intersects in a reference point, whereby the reference point is selected as the origin of the coordinate system, whereby the w-vector that runs through the reference point is tilted in such a way that the implant axis lies in the v, w-plane, whereby the v, w-plane forms a first base plane and whereby a representational plane that is parallel to the first base plane is selected, whereby in a second case, the u vector intersects the implant axis in a reference point and is parallel to the tangent on the panoramic curve in the perpendicular point of the reference point to the panoramic curve, whereby the w-vector of the coordinate system is tilted in such a way that the implant axis lies in the u, w-plane, whereby the u, w-plane forms a second base plane and whereby a representational plane that is parallel to the second base plane is selected. | 11-25-2010 |

20140342120 | METHOD FOR PRODUCTION OF GLASS COMPONENTS - A method for the production of glass components, an apparatus for carrying out the method and a glass component that is obtainable through the method are provided. The method is a drawing method wherein a forming zone of a preform is heated to a temperature that allows drawing of the glass. The method is characterized in that the forming zone of the preform is very small. Thereby the width of the preform is decreased to a smaller extent than its thickness. The glass components that can be obtained by this method have very smooth surfaces. | 11-20-2014 |
20140357467 | METHOD FOR REDRAWING OF GLASS - A drawing method for glass is described. The method provides glass components that have a strongly increased ratio of width to thickness when compared to the preform, which makes the manufacturing of flat glass components more economical. The method purposefully controls the temperature distribution within the preform. | 12-04-2014 |
20150068251 | Method for drawing glass strips - A method for producing a glass strip is provided. The method includes providing a glass preform with flat cross section, wherein the width of the cross section is at least five times greater than its thickness, wherein the cross section tapers into the edge regions in such a way that the thickness of the glass preform relative to its side edges amounts to at most two-thirds of the maximum thickness of a plate-shaped center region of the glass preform; heating the glass preform within a deformation zone, so that the glass found in the deformation zone softens; and applying a tensile force onto the glass preform in the direction perpendicular to the cross section, so that the glass preform is drawn in length in the deformation zone. | 03-12-2015 |
