Abstract: Electrically controllable device having variable optical/energy properties in transmission or in reflection, comprising at least one carrier substrate provided with a stack of electrochromically functional layers, including at least two electrochromic active layers, separated by an electrolyte, the said stack being placed between two current leads, namely the lower current lead and the upper current lead respectively (“lower” corresponding to the current lead closest to the carrier substrate, as opposed to the “upper” current lead that is furthest from the said substrate), characterized in that the stack of functional layers is joined to at least one polymer film, the percentage shrinkage of which is between 0.6 and 2.0% and preferably between 0.8 and 1.5%.

Abstract: A system for sintering a quartz tube, such as a quartz fiber optic sleeve tube. The system comprises a furnace for heating the quartz tube to a temperature of at least 1400° C. in a controlled atmosphere, a support rod assembly for the quartz tube, and means for positioning the quartz tube and a portion of the support rod assembly within the furnace. The support rod assembly includes a cylindrical support rod that straightens and supports the quartz tube and prevents tapering of the inner diameter due to creep, and at least one retaining portion coupled to at least one end of the cylindrical support rod for preventing slippage of the quartz tube from the support rod assembly. A mandrel assembly for fabricating a quartz fiber optic sleeve tube, a method of making a quartz fiber optic sleeve tube using the mandrel assembly, and a quartz fiber optic sleeve tube are also disclosed.

Abstract: A fused quartz article, such as a muffle tube or crucible, with enhanced creep resistance. The enhanced creep resistance is the result of controlled devitrification of the fused quartz article. Controlled devitrification is achieved by coating the article with a colloidal silica slurry doped with metal cations, such as barium, strontium, and calcium. The metal cations in the slurry promote nucleation and growth of cristobalite crystals into the fused quartz at temperatures in the range from about 1000° C. to about 1600° C. The cristobalite has significantly. higher viscosity, and therefore greater creep resistance at elevated temperatures, than fused quartz. Methods for applying a doped coating to a fused quartz article and improving the creep resistance of a fused quartz article are also disclosed.
