摘要： In a vertical glass drawing process, an edge guiding assembly (33) located between a glass forming apparatus (41) and a glass sheet separating apparatus (20) reduces horizontal motion of the glass ribbon (13) from which the glass sheets (11) are removed and results in the reduction of the difference in stress levels between the top and bottom edges of a glass sheet (11) made by the process. The edge guiding assembly also provides a reduction of the variation of stress levels between successive sheets of glass made by the vertical drawing process.

The cooling can take place along the entire length of the ribbon (15) or at selected locations, e.g., in the portion (50) of the draw which includes the glass transition temperature region (31) or the portion (60) of the draw where individual glass sheets (13) are cut from the ribbon (15).

摘要： An endless electrophotographic member, such as a developer roller, which indicates an improved resistance to nip banding. The improvement to nip banding may be provided by the use of an organic salt within a roller surface region. The roller may provide, at a nip location, a resistive surface layer having an electrical resistance that avoids the development of nip banding and relatively dark regions on printed media.

摘要： Methods for forming optical fiber preforms are disclosed. According to one embodiment, a method for forming an optical fiber preform includes forming a preform core portion from silica-based glass soot. The silica-based glass soot may include at least one dopant species for altering an index of refraction of the preform core portion. A selective diffusion layer of silica-based glass soot may be formed around the preform core portion to form a soot preform. The selective diffusion layer may have an as-formed density greater than the density of the preform core portion. A diffusing species may be diffused through the selective diffusion layer into the preform core portion. The soot preform may be sintered such that the selective diffusion layer has a barrier density which is greater than the as-formed density and the selective diffusion layer prevents diffusion of the at least one dopant species through the selective diffusion layer.

摘要： A pull roll apparatus and method are described herein that can control a cross-draw tension and a down-draw tension of a glass sheet while manufacturing the glass sheet. In one embodiment, the pull roll apparatus includes a first driven stub roll pair, a second driven stub roll pair and a control device (e.g., PLC) that controls the first and second driven stub roll pairs while a first edge portion of the glass sheet is drawn between two vertically downtilted rolls associated with the first driven stub roll pair and while an opposing second edge portion of the glass sheet is drawn between two vertically downtilted rolls associated with the second driven stub roll pair. If desired, the pull roll apparatus may include a pulling roll assembly (located below the first and second driven stub rolls) or another set of driven stub roll pairs (located below the first and second driven stub roll pairs).
