  • Patent number: 6548142
    Abstract: 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.

  • Patent number: 6479129
    Abstract: 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.

  • Patent number: 6387511
    Abstract: These glass bodies are light weight porous structures such as a boules of high purity fused silica or ultra-low expansion glass. More specifically, the porous structures are supports for mirror blanks. Porous glass is made utilizing flame deposition of pure silica or doped silica in a manner similar to the production of high purity fused silica. Bubbles or seeds are formed in the glass during laydown. Several means of creating and controlling these seeds are available. The processes use incomplete combustion to create the bubbles. There are a number of different steps to create the incomplete combustion. One such step is a short distance between the hydrolysis flame and the glass precursor.

  • Patent number: 6313057
    Abstract: A fused silica refractory material made from quartz grains and a method of making the material which contains calcium oxide binder in an amount less than one weight percent. The reduction in calcium oxide binder prevents the degradation of fused silica refractory bricks in furnace environments containing alkali vapors, such as in oxygen-fuel fired glass furnaces. The invention also includes a method of preventing the degradation of silica refractory material by alkalis.

  • Patent number: 6071839
    Abstract: These color television (CTV) panel tint glasses involve using base CTV panel glass compositions with enhanced levels of Ni and Co colorants. The approach uses non-lead CTV panel glass compositions with high levels of Ni and Co oxide as colorant glasses for tinting clear CTV non-lead panel glass. Nickel oxide was varied from 2 to 18%, while cobalt oxide was varied from 0.2 to 2%. A preferred range of compositions with cobalt oxide levels below 1% and nickel oxide levels below 10% was found to be very acceptable for CTV panel colorants.

  • Patent number: 5618589
    Abstract: This method and apparatus provide for uniformly coating a hot elongate member with a powder coating. The elongate member and power carry an electrostatic charge which aids in providing the uniform powder coating. This method and apparatus electrostatically charge and heat the elongated member prior to entering a powder coating booth. In the booth, we sequentially discharge the powder coating, electrostatically charge the powder coating and then coat the elongated member with the charged powder coating. In one development, this method and apparatus uniformly powder coats window lineals directly on a pultrusion line.
