Patent number: 11872188Abstract: A glass tube semi-finished product or a hollow glass product manufactured from the glass tube semi-finished product is provided with a first marking with information regarding origin and manufacture of the glass tube semi-finished product and a second marking, the information of which second marking is linked to the information of the first marking, so as to enable a determination regarding authenticity of the glass tube semi-finished product, origin of the glass tube semi-finished product, and/or origin of an apparatus with which the first and/or second marking was generated on the glass tube semi-finished product. The first marking is a marking that is produced at temperatures above the transformation temperature of the glass in a counterfeit-proof manner. The combination of two markings provides a high level of protection against counterfeiting.Type: GrantFiled: December 8, 2017Date of Patent: January 16, 2024Assignee: SCHOTT AGInventors: André Witzmann, Ulla Trinks, Reinhard Männl

Patent number: 11542195Abstract: A glass tube semi-finished product or a hollow glass product manufactured from the glass tube semi-finished product is provided with a first marking with information on the origin and/or tube-specific production data of the glass tube semi-finished product, which marking is read from the hollow glass product after its manufacture to determine the origin and/or the tube-specific production data of the glass tube semi-finished product, e.g., to identify the semi-finished glass tube from which the hollow glass product has been made, and/or trace the tube-specific production data of this glass tube semi-finished product. This means that the entire supply chain for the hollow glass product from the supplier of the originally used glass tube semi-finished product up to the end product can be determined. The physical and chemical characteristics of the glass tube semi-finished product are not altered for producing the first marking.Type: GrantFiled: December 8, 2017Date of Patent: January 3, 2023Assignee: SCHOTT AGInventors: André Witzmann, Ulla Trinks, Reinhard Männl

Patent number: 5433486Abstract: The invention refers to a process and an arrangement to connect and seal tubes (2, 4) made of glass, metal or ceramic materials, that are joined to form flue-gas pipes. The sealing system according to the invention is distinguished by the fact that it can be used for exhaust gas pipes as well as for diminished cross-sections for chimneys, for example, since the sealing material is used in such a way that the overlapping pipes (2, 4) are connected in gas-tight manner even in the case of varying pressure conditions, and that the sealing material (8) is sufficiently resistant to acid, water and temperature to be used in the removal of hot, acid gases. In a preferred form of construction, the pipes (2, 4) are fixed together before applying the anorganic sealing material (8). The pipes are either fixed by punctually applied, quick-setting adhesive (6) or secured together by a pipe clamp (14) attached at the circumference of the pipes.Type: GrantFiled: May 13, 1993Date of Patent: July 18, 1995Assignee: Schott-Rohrglas GmbHInventors: Reinhard Mannl, Herbert Jung

Patent number: 5300134Abstract: An apparatus and process is provided for the deformation of the heat-softened end of a glass tube. In the formation of hollow articles such as, for example, vials from glass tubes, either large processing pauses occur or the formation elements have to be moved with high speed to the next tube being processed. To keep the processing pause short a forming roller is provided, which is shifted back and forth relative to the glass tube. Shifting of the forming roller takes place in such a manner that the forming roller, toward the end of the rolling, is at the starting position for forming the next glass tube.Type: GrantFiled: May 17, 1993Date of Patent: April 5, 1994Assignee: Schott GlaswerkeInventors: Reinhard Mannl, Alfons Wolfrum, Franz Neumeier

Patent number: 5252115Abstract: A device and forming finger for forming a mouth area on a glass vial and a process for forming the glass vial wherein wear of the finger is reduced to a minimum so that better production tolerances for the formed mouth is possible. This is achieved by a forming finger being allocated either to each glass tube of a vial machine, or by providing play to the forming finger, or by providing the forming finger with lateral recesses. Preferably, the forming finger has a ratio of cross-sectional surface to circular segment area of the forming finger which is larger than or equal to 0.55.times.r. The aforedescribed forming fingers are used in all vial machines, in which from many glass tubes in a cycle, step by step vials are produced by rolling and melting the tube pieces.Type: GrantFiled: September 10, 1991Date of Patent: October 12, 1993Assignee: Schott GlaswerkeInventors: Reinhard Mannl, Alfons Wolfrum, Franz Neumeier

Patent number: 5178401Abstract: Chucks for glass tubes should be designed so that, on the one hand, they grasp the glass tube gently so that the tube is not destroyed, and, on the other hand, so that they hold it securely enough so that a proper processing of the glass tube is possible. This causes a degree of technical complexity which enlarges the dimensions of the chuck and leads to a narrow diameter range for the clampable glass tubes. For other diameter ranges, the chucks have to be changed. The chuck according to the invention has a wide diameter range with small outside dimensions. The chuck has clamping jaws which can be moved radially with respect to its longitudinal axis and has a distance from the longitudinal axis determined by a pressure sleeve, which is connected to the clamping jaws by a forced guidance device. The forced guidance forms an angle of 30.degree. to 60.degree., and preferably 45.degree., with respect to the longitudinal axis. The chuck is used to hold glass tubes in a machine for producing vials.Type: GrantFiled: July 31, 1991Date of Patent: January 12, 1993Assignee: Schott GlaswerkeInventors: Reinhard Mannl, Alfons Wolfrum, Franz Neumeier

Patent number: 5080705Abstract: Methods of an apparatus for producing profiled glass tubing utilizing the Danner process comprise flowing the molten glass over profiled blowpipe heads which are "super-profiled" in that the angles of ridges and grooves are more acute than the ridges and grooves resulting in the glass tubing. The particular profiles of the glass tubing are controlled by selecting the necessary drawing speed, viscosity of the glass, internal air pressure at the blowpipe head and throughput rate of the glass melt.Type: GrantFiled: May 29, 1991Date of Patent: January 14, 1992Assignee: Schott GlaswerkeInventors: Franz Ott, Reinhard Mannl

Patent number: 4981505Abstract: A heat-sealable glass container is heat-sealed by an apparatus which heats the container with an infrared lamp while rotating the container and elongating the heat-softened top portion. The elongation of the softened glass pulls the glass to a point and results in an airtight seal.Type: GrantFiled: March 31, 1989Date of Patent: January 1, 1991Assignee: Schott-Ruhrglas GmbHInventor: Reinhard Mannl

Patent number: 4898605Abstract: A glass vessel, in particular an ampoule, having a prestress produced at a predetermined spot of the vessel which permits an automatic opening of the vessel at the predetermined spot following scratching by means of a suitable tool. The prestress, which is produced exclusively by means of an earlier thermal treatment without the application of a tool exhibits a stress profile in which an initially produced annular tensile stress ring, is overlapped at a predetermined spot by a point-shaped compressive stress zone that is produced subsequently.Type: GrantFiled: April 21, 1989Date of Patent: February 6, 1990Assignee: Schott Ruhrglas GmbHInventor: Reinhard Mannl

Patent number: 4516998Abstract: The present invention relates to a new method of making tubular vials and ampules from glass tubing. The method according to this invention is essentially characterized in that the glass tubing used is closed at both ends and has a dot-shaped opening close to one of the sealed ends. The opening can be sealed by a film to prevent impurities from entering the glass tubing. Throughout the operational process in the production of vials and ampules, a slight excess pressure exists in the glass tubing by applying heat, which further prevents impurities from entering the glass tubing.Type: GrantFiled: November 16, 1983Date of Patent: May 14, 1985Assignee: Schott-Ruhrglas GmbHInventors: Hans-Georg Ritt, Hartmut Luneberg, Reinhard Mannl, Alfred Grillmeier
