Patent number: 6200658Abstract: Numerous applications for hollow glass bodies made from low melting glass material require an increase in the chemical resistance of the interior surface of the glass body. In order to avoid a disadvantageous de-alkalizing process the hollow glass body must be provided with an interior coating in a comparatively expensive prior art process. In an improved process according to the invention a glass tube acting as a semifinished product from which the hollow glass body is made is provided with an interior coating of oxide material, preferably SiO2, Al2O3, TiO2 or mixtures thereof, having a predetermined coating thickness according to the required chemical resistance or working conditions for forming the glass body and then the hollow glass body is made from the glass tube. The coating is advantageously provided by means of a PICVD process.Type: GrantFiled: January 19, 1999Date of Patent: March 13, 2001Assignee: Schott GlasInventors: Marten Walther, Michael Spallek, Burkhardt Danielzik, Martin Heming, Johannes Segner

Patent number: 6177148Abstract: The invention concerns a plasma CVD system (in particular a plasma pulse CVD system) with an array of microwave antennas. According to the invention, in order to improve the homogeneity of the layer, interference is prevented by controlling adjacent antennas in a chronologically offset manner. To that end, microcapsules are provided within the macrocapsules of the plasma pulse CVD process. Additionally, the uniformity of the layer deposition at the interfaces between adjacent modules can be optimized by radio-frequency excitation by means of suitable electrodes, magnetic fields or the configuration of the gas inlets. The surface coated in an operating cycle can thus be scaled as required.Type: GrantFiled: May 10, 1999Date of Patent: January 23, 2001Assignee: Carl-Zeiss-StiftungInventors: Marten Walther, Wolfgang Möhl, Burkhard Danielzik, Markus Kuhr, Roland Hochhaus, Hartmut Bauch, Martin Heming, Thomas K{umlaut over (u)}pper, Lars Bewig

Patent number: 6025013Abstract: A PCVD process for producing coating layers of uniform thickness of domed substrates. The substrate surface to be coated is arranged in relation to the gas passage surface of a gas showerhead. In order to determine the appropriate processing parameters, in a first series of tests for one type of substrate to be coated, the size of the gas passage surfaces and the gas mass flows through the gas passage surfaces are kept constant, while the intervals between plasma impulses are gradually modified, from an initial value t.sub.A until an optimum value t.sub.eff is determined, and until the uniformity of the thickness profile of the layers generated on the substrate may no longer be improved. If required, during a second series of tests, the value t.sub.eff may be kept constant, while the thickness profile of the layers is further modified by further optimizing the local parameters and/or the gas mass flows until layer uniformity may no longer be improved.Type: GrantFiled: January 22, 1997Date of Patent: February 15, 2000Assignee: Schott GlaswerkeInventors: Martin Heming, Ulrich Lange, Roland Langfeld, Wolfgang Mohl, Jurgen Otto, Volker Paquet, Johannes Segner, Martin Walther

Patent number: 5900285Abstract: A plastic vessel has a barrier coating comprising sequentially arranged barrier layers of organic polymer and of inorganic oxides, nitrides or oxynitrides. The barrier coating preferably has at least two inorganic barrier layers. The thickness of the inorganic barrier layers lies between 2 and 300 nm and the thickness of the organic barrier layer lies between 2 and 1000 nm. The total thickness of the layer packet should not exceed 0.1 mm.Type: GrantFiled: November 21, 1997Date of Patent: May 4, 1999Assignee: Schott GlaswerkeInventors: Marten Walther, Martin Heming, Michael Spallek, Gudrun Zschaschler

Patent number: 5822472Abstract: The invention relates to a process for determing lumnescence with a planar dielectric optical sensor platform which consists of a transparent substrate to which a thin transparent waveguiding layer is applied, which sensor platform is provided with a coupling grating for the input-coupling of the excitation light and the refractive index of the substrate is lower than the refractive index of the waveguiding layer, by briging a liquid sample as superstrate into contact with the layer, and measuring the luminescence produced by substances having luminescence properties in the sample, or by substances having luminescence properties immobilized on the layer, optoelectronically. The invention also relates to the use of the process in quantitative affinity sensing and to the use thereof for the quantitative determination of luminescent constituents in optically turbid solutions, and to sensor platform for carrying out the process.Type: GrantFiled: March 4, 1997Date of Patent: October 13, 1998Assignee: Novartis CorporationInventors: Burkhard Danielzik, Gert Ludwig Duveneck, Martin Heming, Dieter Neuschafer, Johannes Segner

Patent number: 5712705Abstract: Arrangement for analysis of substances at or near the surface of an optical sensor with at least one wave-guiding film and at least one multidiffraction grating coupler for in-coupling and out-coupling of light beams, in which at least two light beams enclosing an angle .alpha. relative to one another are coupled in and by which at least two light beams enclosing an angle .phi. relative to one another are coupled out, and with a detection system for detecting the out-coupled light beams, wherein in-coupling and out-coupling are effected on one and the same side of the sensor and the in-couple beams and out-couple beams lie in different quadrants of the plane of incident light, and the angle .alpha. between the in-couple beams is greater than the angle .phi. between the out-couple beams. The arrangement has multiple uses for determining physical or chemical measured quantities based on the interaction of the guided light waves with the medium at or near the sensor surface.Type: GrantFiled: July 7, 1995Date of Patent: January 27, 1998Assignees: Carl Zeiss Jena GmbH, F.

Patent number: 5480687Abstract: An optical waveguide is disclosed with a substantially planar substrate and a waveguide layer applied to the substrate. The invention resides in that the substrate consists of a synthetic resin or of a material having a high organic proportion. This has the advantage that the high index of refraction of the inorganic waveguide layer is combined with the material properties of the synthetic resin substrate, such as, for example, breaking resistance, plastic and thermoplastic moldability, photochemical structuring ability, and others.Type: GrantFiled: April 7, 1995Date of Patent: January 2, 1996Assignees: Schott Glaswerke, Hoffmann-La Roche, A.G.Inventors: Martin Heming, Roland Hochhaus, Ralf Kersten, Dieter Krause, Jurgen Otto, Volker Paquet, Johannes Segner, Christof Fattinger
