摘要： In the process for applying a protective plastic coating to a glass optical waveguide fiber by the application of a curable liquid coating material thereto and the subsequent curing of the liquid coating to a protective plastic layer, the surface of the glass optical fiber is conditioned prior to the application of the liquid coating material thereto by replacing air adjacent the fiber surface with a selected gas preferably exhibiting high solubility in the liquid coating composition and resisting bubble formation in the liquid coating layer as it is formed.

摘要： The present invention describes an extrusion process for manufacturing a glass honeycomb structure having a variety of shapes and sizes depending on its ultimate application. Unlike prior art honeycomb structures made from ceramics, the inventive glass honeycomb can be readily viscously bent and/or redrawn. Furthermore, the inventive honeycomb structure is lightweight, yet able to support heavy loads on its end faces. Therefore, the inventive honeycomb can be used as a light-weight support for such objects as mirrors. These honeycombs can be used singularly or in aggregates to provide such support. Embodiments are described wherein the mass of the honeycomb is further reduced by removing select portions of the honeycomb without deleteriously impacting its ability for load bearing.

摘要： The present invention describes a glass honeycomb structure having a variety of shapes and sizes depending on its ultimate application. Unlike prior art honeycomb structures made from ceramics, the inventive glass honeycomb can be readily bent and/or redrawn. Furthermore, the inventive honeycomb structure is lightweight, yet able to support heavy loads on its end faces. Therefore, the inventive honeycomb can be used as a light-weight support for such objects as mirrors. Other useful properties of the extruded glass honeycomb are its high softening temperature, its transparency to ultraviolet and visible light, and its ability to be redrawn. Embodiments that rely upon one or more of these properties include: a bio-reactor, a membrane reactor, a capillary flow controller, a high efficiency filtration system, in-situ water treatment, high temperature dielectric material, and photonic band gap material.

摘要： The present invention describes an extrusion process for manufacturing a titanium-containing silicate glass honeycomb structure, having a variety of shapes and sizes depending on its ultimate application. The titanium-containing glass honeycomb has a very low coefficient of thermal expansion (CTE) and the CTE can be varied by adjusting the titanium level to match the CTE of members that are bonded to the honeycomb. Furthermore, the inventive honeycomb structure is lightweight, yet able to support heavy loads on its end faces. Therefore, the inventive honeycomb can be advantageously used as a light-weight support for such objects as mirrors. Especially contemplated is using these inventive honeycomb supports for mirrors used in extraterresial environments where temperature extremes are present. These honeycombs can be used singularly or in aggregates to provide such support. Embodiments are described wherein the mass of the honeycomb is further reduced by removing select portions of the honeycomb without deleteriously impacting its ability for load bearing.

摘要： An optical waveguide fiber is provided which comprises (a) a glass core; (b) a glass cladding which includes a barrier layer in the region of its outer surface which has an index of refraction and an absorption coefficient which are greater than the index of refraction and the absorption coefficient of the remainder of the cladding; and (c) a polymeric protective coating which is in direct contact with the outer surface of the cladding and which has an index of refraction which is less than the index of refraction of the barrier layer and less than the index of refraction of the remainder of the cladding. In certain preferred embodiments, the polymeric coating is selected from the group consisting of RTV silicone rubbers, UV curable silicones of the thio-ene type, UV curable silicone acrylates, and fluoropolymeric coatings.

摘要： Optical fibers are coated under pressure to reduce the amount of bubbles entrapped in the coating and provide good coating concentricities. The fiber is drawn axially thru a thin-walled, cylindrical flow distribution sleeve which is located between a guide die and a sizing die. The sleeve contains a plurality of evenly distributed holes the number and size of which is such that radial flow of liquid toward the fiber is maintained over the entire length of the sleeve which is less than 1.27 cm.
