Disclosed herein are systems for shaping glass structures, comprising a shaping mold; a magnetic field generator; and a susceptor plate positioned substantially between the shaping mold and the magnetic field generator. Also disclosed herein are systems for shaping a glass structures, comprising a magnetic field generator comprising at least one induction coil and a one power supply connected to the at least one induction coil; and a susceptor plate having a first surface proximate the at least one induction coil and an opposing second surface proximate the glass structure. Further disclosed herein are methods for heating glass structures, comprising positioning the glass structure on a shaping mold; introducing the shaping mold and glass structure into a furnace; and indirectly heating at least a portion of the glass structure using at least one induction heating source.

A local bend is formed in a glass sheet (10) by supporting large flat areas (14, 16) of the glass sheet (10) on large flat supports (106L, 106R) that are articulated relative to each other while leaving an area (12) of the glass sheet in which the local bend is to be formed unsupported. A combination of bending forces applied to the glass sheet (10) by articulation of the large flat supports (106L, 106R) and local heating (110) of the unsupported area (12) of the glass sheet (10) produces the local bend.

A method of modifying a substrate formed of non-deformable material is disclosed. In some embodiments, techniques are disclosed for identifying a region of a planar substrate that is susceptible to stretching during a subsequent shaping operation. In some embodiments, techniques are disclosed for adding an amount of non-deformable material to the planar substrate at an identified location and in a single operation, acting on the substrate until the substrate has a shape corresponding to a uniform thickness and a three-dimensional curvature.

Glazing, such as for vehicles, includes a sheet of glass-ceramic that has different regions with different transmission properties, including a first visually clear region that blocks infrared, a second visually clear region that allows transmission of infrared, and a third colored region.

This disclosure relates to a method for producing a mirror of a microlithographic projection exposure apparatus, a first mirror part and a second mirror part being provided, which are in contact in the region of a first connecting surface of the first mirror part and a second connecting surface of the second mirror part. For forming a durable connection between the first mirror part and the second mirror part, the first mirror part and the second mirror part are heated up to a holding temperature of at least 400? C. and are kept at the holding temperature during a holding time. After the holding time has elapsed, the first mirror part and the second mirror part are cooled down to a first cooling temperature at a first cooling rate of less than or equal to 100 K/h.

A method of shaping a glass sheet includes heating the glass sheet to a temperature for shaping, positioning the glass sheet on a shaping support, and shaping the glass sheet on the shaping support, wherein during the shaping of the glass sheet at least one portion of the glass sheet is deliberately cooled. The shaping of the glass sheet involves press bending a heat softened glass sheet between a lower shaping support and an upper shaping member, wherein during the shaping of the glass sheet on the shaping support only a portion of the major surface of the glass sheet facing the lower shaping support is cooled by directing one or more jets of air onto said portion.

There is provided an apparatus for molding a glass substrate, the apparatus including a pre-heating unit, a molding unit, and a cooling unit sequentially arranged, wherein the pre-heating unit includes a pre-heating body and a glass substrate holder, wherein the molding unit includes: a molding body having a vacuum port, a molding support on the molding body, the molding support being configured to support an edge of a glass substrate, and a heating element configured to heat the molding body, and wherein the cooling unit includes a cooling body and a cooling plate.

The present invention discloses a vehicle glazing having a sharply curved portion and the method for bending such glazing. The sharply curved portion of the glass may extend along the surface of the glass. The sharply curved portion is obtained by locally heating by means of a laser source, heating the portion of the glass to a temperature sufficiently high enough to allow said portion of glass to bend. In preferred embodiments, the sharply curved portion comprises a first bent portion described by a first radius and a second bent portion described by a second radius, wherein the point where the radiuses of the first and second bent portions change their orientation generate an inflection point. The radius of curvature of the first and second bent portions is of less than 150 mm.

A method of making articles from preformed materials includes placing a preformed material on a mold such that a non-quality region of the preformed material contacts the mold and a quality region of the preformed material is free of contact with the mold. A non-contact support is provided to the quality region to control sagging of the quality region. A reformable area of the preformed material is formed into a select shape by contacting the reformable area with a forming tool while restricting contact between the forming tool and the reformable area to the non-quality region. After the forming of the reformable area, an article is extracted from the quality region.

A system and process for forming a curved glass laminate article is provided. The process and system utilizes co-sagging of a stack of glass sheets of different thicknesses and different glass materials. During co-sagging the thicker glass layer is placed on top of the thinner glass layer. In this process, shape mismatch is avoided by selecting/controlling the glass materials of the sheets of glass such that the viscosity of the lower, thinner sheet during co-sagging is greater than the viscosity of the thicker glass sheet.
