摘要:
The present invention relates to a fiber coated with a water blocking material that includes an essentially water free dispersion comprising a superabsorbent polymer and a dispersing medium. The fibers made according to this invention may be used, for example, as fiber reinforcing material used in the manufacture of cables, and in particular in yarns for fiber optical cables that use optical light wave guides for optical communication transmissions.

A forehearth color concentrate comprising a non-smelted agglomerated interspersion of particles for use in coloring, said concentrate comprising by weight from about 50% to about 95% of a glass component and from about 4% to about 50% of a binder, said glass component comprising by weight from about 15% to about 35% chromium oxide. The present invention further provides a method of using the color concentrate.

A radioactive microsphere for radiation therapy of a mammal comprising a biologically compatible glass material containing a beta or gamma emitting radioisotope distributed substantially uniformly throughout the glass. Advantageously, the radioisotope is produced by irradiation of the microsphere.
摘要:
A method for splicing coated optical fibers. The outer coating layer of two coated optical fiber ends to be joined is removed from respective end portions thereof. The inner optical fibers so exposed are then coated with a layer of UV-curable resin. After the resin layer has been hardened by irradiating it with ultraviolet radiation, the coated portion may be securely clamped without fear of damaging the optical fibers. The clamped end portions may then be moved toward one another in order that they may be fused together.

摘要:
Flexible electrically switchable panels or glazing structures and methods of manufacturing such flexible electrically switchable panels or glazing structures are provided. Particularly, methods and processes are disclosed that enable fast and efficient cutting and shaping of flexible glazing structures into any desired shape and size. In certain embodiments, methods and processes are disclosed whereby barrier lines are formed to define regular or irregular cutting lines and seals. In further embodiments, methods and processes are disclosed whereby notches are defined to expose upper and lower substrate conductive surfaces. In still further embodiments, methods and processes are disclosed whereby glazing structures of irregular shapes and sizes are formed.

Disclosed is use of a vitreous inorganic fiber in the knowledge that it has a composition meeting the criterion that the calculated sum of the free energies of hydration of the compounds that would or could be present at equilibrium (on the basis of knowledge, informed belief or reasonable assumption) is more negative than −10 kcal/100 grams of composition. Such compositions are saline soluble.
摘要:
A drawn glass-coated metallic member has a thermal contraction coefficient differential such that the thermal contraction coefficient of the glass is less than that of the metallic member. The thermal contraction coefficient differential is maintained within a predetermined range during drawing. The glass is placed under residual compression, interfacial bonding between said glass and said wire is substantially uniform, and surface cracking and bond breaks between metal and glass are substantially prevented. A dynamic balance is maintained between the surface tension of the molten alloy and the resistance to high temperature deformation by the glass vessel in which it is contained, enabling the production of glass-coated amorphous or nanocrystalline alloy members having predefined cross-sectional shapes.
摘要:
The present invention relates to a liquid, radiation-curable coating composition for the coating of glass surfaces which comprisesA) 56 to 89% by weight of at least one diethylenically unsaturated polyurethane optionally containing urea groups,B) 3 to 30% by weight of at least one ethylenically unsaturated monomer,C) 0.5 to 8% by weight of at least one photoinitiator andD) 0.05 to 6% by weight of an alkoxysilane,the sum total of the components A to D being 100% by weight in each case.The coating composition uses1.) one or more ethylenically unsaturated monomers containing carboxyl groups, optionally together with other ethylenically unsaturated monomers as the component B and2.) an alkoxysilane containing epoxide groups as the component D.These coating compositions are employed for the coating of glass surfaces, in particular of optical glass fibers, and are distinguished by good adhesion even under humid conditions.
摘要:
A composition for forming a high temperature, alkali resistant refractory fiber. The compositional formulation, by weight, is 46-52% silica, 32-38% alumina, 13-18% zirconia with a silica to zirconia ratio in the range from 2.6 to 3.8. These fibers have a maximum service temperature in the range of 2550.degree. F. (1400.degree. C.) to 2650.degree. F. (1455.degree. C.) and exhibit better shrinkage resistance than similarly rated commercially available refractory fiber.
