Patent number: 11932573Abstract: An element composed of glass displaying reduced electrostatic charging is provided. The element is suitable as a housing component for electronic elements, an element implantable in the human or animal body including glass tubes for reed switches or transponders and/or implants. The glass includes at least one alkali metal and/or an alkali metal oxide and has a surface. The concentration of at least one alkali metal and/or the alkali metal oxide increases from the surface in a direction of an interior of the element in such a way that a maximum concentration of the alkali metal and/or the alkali metal oxide occurs at a distance of not more than 60 nanometres, measured perpendicularly from the surface.Type: GrantFiled: January 8, 2020Date of Patent: March 19, 2024Assignee: SCHOTT AGInventors: Johann Daimer, Martin Zöttl

Patent number: 8439241Abstract: The invention is based on the object of improving the detachment of portions of a glass rod to the extent that a very planar, uniform fracture surface is produced. For this purpose, an apparatus according to the invention for detaching portions of glass rods comprises a device for the parallel holding and lateral fixing of a number of glass rods, a scoring wheel holder with a scoring wheel rotatably mounted parallel to the axis of the glass rods, at least one pressing spring for pressing the scoring wheel and the glass rods against one another, a device for guiding the glass rods and the scoring wheel past one another in a direction perpendicular to the axis of the glass rods, a holddown means for pressing against the glass rods, a breaking bar and a breaking beam, the breaking bar being arranged opposite, between the holddown means and the breaking beam.Type: GrantFiled: March 16, 2007Date of Patent: May 14, 2013Assignee: Schott AGInventors: Albert Stangl, Johann Piegendorfer, Martin Zöttl, Michael Kopp

Patent number: 7538892Abstract: In order to provide light guides, in particular in the form of glass rod portions, with improved end faces, the invention provides a method for examining glass rods, in particular light guides, in which the glass rods are arranged in front of two cameras, the cameras recording the end faces from the sides, in two different radial viewing directions with respect to the longitudinal axis of the glass rods, and the planarity and angularity of the contour of the end faces being optically and contactlessly determined with both cameras on the basis of the recordings, and a glass rod automatically being rejected and/or sorted by means of a rejecting/sorting device if there is any deviation of the planarity or angularity of the end faces of the glass rod from a respectively prescribed set range.Type: GrantFiled: May 15, 2007Date of Patent: May 26, 2009Assignee: Schott AGInventors: Ernst Parzl, Johann Piegendorfer, Martin Zöttl

Publication number: 20060141181Abstract: The invention relates to glass tubes for technical applications, especially for electrical or magnetic components, such as reed switches for example. According to a first embodiment, the glass tube has an inner bore (23) and at least one cross-sectional constriction (X) whereby the relationship applicable between the respective cross-sectional constriction (X) and the diameter (d) of the circumference of inner bore (23) is: x greater than or equal to 0.02*d, more preferably x greater than or equal to 0.1*d. According to a further embodiment, the glass tube has at least one inner bore with at least one inner edge, wherein the radius of curvature of the respective inner edge is less than or equal to 0.1 mm and preferably less than or equal to 0.03 mm. The glass tube is used as a preform for a subsequent redrawing process. The preform is formed by casting a molten glass into a shaft in the interior of which is located a shaping means for defining the inner bore.Type: ApplicationFiled: December 7, 2005Publication date: June 29, 2006Inventors: Andreas Langsdorf, Frank Buellesfeld, Ulrich Lange, Martin Zoettl
