摘要:
A fused silica body comprising a layer of vitreous silica adjacent at least a portion of an inner surface is described in embodiments herein. In other embodiments, a method of making a fused silica body with a layer of vitreous silica adjacent at least a portion of an inner surface is described herein, comprising heating at least a portion of the inner surface to the point of vitrification. In certain embodiments, the method involves passing a linear local heat source over the inner surface in a particular manner, such as a helical fashion transverse to the linear shape, and may involve creating on the inner surface of the body overlapping swaths of temporarily melted silica material.

An apparatus for stabilizing a sheet material by near-field levitation comprises a heater plate including a heating element and a radiation surface which vibrates when the heater plate receives an acoustic wave. The apparatus further comprises at least one vibration source coupled to the heater plate and operable to transmit the acoustic wave to the heater plate.

A container for storing and/or applying a pharmaceutical substance is provided that includes a basic body made of glass and a first connecting body made of glass. The basic body has a substantially hollow cylindrical form and encloses a cavity. The basic body has a first end with a first opening. The first connecting body has a thin channel communicating with the first opening. The first connecting body is connected with the basic body in a first connection area. The first connection area has a first absorption zone that has a higher radiation absorption for electromagnetic waves in a predetermined wavelength range (λ) than portions of the basic body outside the first absorption zone (Z1).

摘要:
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.
摘要:
An electrical heating conductor arrangement for heating a furnace has one or more strip-shaped portions with a generally horizontal sheet-like extent. The strip-shaped portions are formed by individual bands which have along their width an arcuate curvature with respect to a horizontal plane. The individual bands are partially mounted by at least one bearing element pivotably in the longitudinal direction of the respective band.
摘要:
An apparatus and method for bending and/or tempering glass substrate(s) are provided. The amount of near-IR radiation which reaches the glass to be bent and/or tempered is limited (e.g., via filtering or any other suitable technique). Thus, the IR radiation (used for heating the glass) which reaches the glass to be bent and/or tempered includes mostly mid-IR and/or far-IR radiation, and not much near-IR. In such a manner, coating(s) provided on the glass can be protected and kept at lower temperatures so as to be less likely to be damaged during the bending and/or tempering process. Heating efficiency can be improved.

Heating efficiency can be improved. A ceramic (e.g., aluminosilicate) filter or baffle may be used in certain embodiments in order to reduce the amount of mid-IR and/or far-IR radiation reaching the glass to be tempered and/or bent.
