Abstract: This invention relates to using a production glass furnace to melt waste glass and other glass constituents thereby providing a radiant heat source within the furnace to efficiently gasify organic waste materials recovered from a variety of waste streams to thereby produce a synthesis gas (“Syngas”) that is comprised mostly of carbon monoxide, hydrogen, and carbon dioxide that can be further refined and sold as a high value fuel. The gasification of the organic waste within the production glass furnace has minimal impact on the composition of the glass melt thus allowing for the production of the same range of glass products as if no organic waste was added to the furnace.

Abstract: Disclosed are glass compositions containing Beryllia in addition to various proportions of Silica, Alumina, Calcium, Magnesia, Sodium, Potassium, Iron, Titania, Zirconia, Manganese and/or Phosphorous. Fibers were produced from the disclosed compositions using standard glass processing equipment. These fibers yielded high temperature fibers having low density, high strength, high modulus, excellent glass surfaces requiring very little bonding material to hold the fibers together. Bio solubility is preferably promoted by ensuring that only trace quantities of alumina are present. Fibers having those properties are particularly suitable for producing high temperature glass fiber insulation for use in aircraft and other vehicles.

Abstract: A glass composition is provided for the production of high temperature glass fibers with oxides comprising 1% to 15% Fe2O3+FeO as a fluidizer to lower liquidous temperature and the fiberizing temperature of a mix of high temperature oxides. The glass composition has therein an appropriate content of high temperature oxides to produce glass fiber with high temperature limits and high burn-through properties.

Abstract: Improved glass fibers compositions, typically useful for fire resistant blankets or containers to provide high burn-through resistance at high temperatures of 2,400° F. and higher, and typically comprising silica, sodium oxide, potassium oxide, calcium oxide, magnesium oxide, ferrous+ferric oxide, and titanium oxide; the improved glass compositions may further include alumina, lithium oxide, and boron oxide.

Abstract: Improved glass compositions for glass fibers typically useful for fire resistant blankets or containers to provide high burn-through resistance at temperatures of 2,300° F. and typically comprising 10.23% to 81.81% silica, 2.0% to 26.00% alumina, 3.0% to 15.0% calcium oxide, 0% to 10.50% magnesium oxide, 1.0% to 18.0% ferrous+ferric oxide, and 0% to 4.0% titanium dioxide; the improved glass compositions may include 0% to 9% lithium oxide, 0% to 9% boron oxide, 0% to 6.0% manganese oxide, and 0% to 4.0% phosphorous oxide.

Abstract: A method and apparatus for producing glass fibers wherein molten glass is deposited onto a spinning cup structure. Centrifugal force urges the molten glass outwardly and upwardly along the inner surface of an upstanding wall of the cup structure. The glass is then extruded through small holes in the cup wall. A downflowing stream of hot gas passes downwardly along the outer surface of the cup wall to turn the fibers downwardly while producing an attenuation (reduction) of fiber diameter. The lower portion of the cup side wall is heated to achieve greater temperature uniformity of the fibers as they are formed. A cool gas curtain is formed about the downflowing hot gas stream to somewhat concentrate the hot gas stream for more uniform heating of the downflowing glass fibers.

Abstract: An electrode assembly for a glass melting furnace has an electrode body supported by two elongated steel tubes. Current is supplied to the electrode body by a current supply tube disposed between the two support arms. A holding fixture joins the two support arms to the electrode body. The tube extends through the holding fixture to connect with the electrode body, thus to provide a firm electrical connection with the tube and good mechanical connection with the support arms.

Abstract: A pressure equalizing liquid addition funnel for a closed system reactor is described. The funnel includes an internal valve stem which seats in the outlet port and extends therethrough and which defines a lumen which extends axially from below the outlet port upwardly to a port in the valve stem in the upper portion of said flask. The valve stem then terminates in a valve cap which is threadedly mounted on the funnel whereby rotation of the cap will cause the valve to engage or disengage a valve seat at the outlet.

Abstract: In this energy efficient process for forming glass microfibers, glass pellets are fed at a controlled rate into a rotary fiberizer. The input material is in the form of glass marbles or pellets which are held at a temperature below the liquidus temperature of the glass prior to extrusion through the holes in the fiberizing disc. Centrifugal force causes the semi-soft glass pellets to flow outwardly through the orifices in the fiberizing disc wherefrom they are extruded past the exterior of the disc into a high temperature environment where the temperature of the extruded glass fibers increases and the fibers are additionally subjected to further attenuation of their diameter by the action of a relatively high velocity gaseous stream which acts to stretch out the extruded fibers.

Abstract: An improved glass composition, especially suitable for glass fiber manufacture having good fiberizing characteristics and good physical properties, and containing typically 40.0% to 65.0% silica, 4.0% to 11.0% aluminum oxide, 6.0% to 20.0% sodium oxide, 5.0% to 8.0% magnesium oxide and 6.0% to 17.0% calcium oxide, 4.0% to 12.0% ferric and ferrous oxide, and 0.0% to 7.0% potassium oxide.

Abstract: A nickel/chrome-base alloy, particularly suitable for high temperature molten glass handling and forming apparatus, resistant to oxidation and possessing high rupture strength.

Abstract: This disclosure describes a quick opening valve structure particularly suitable for use in laboratory applications as a stopcock and the like. The structure includes a valve housing, which may be made of glass, and has a barrel section defining a valve chamber and coaxial inlet and outlet branches leading to and from the chamber through respective inlet and outlet ports. The axis of the valve chamber is disposed at an acute angle to the common axis of the ports. A valve plug, which may be made of a polymeric material, threads into and out of the valve chamber. The plug has an inclined end face disposed at an angle corresponding to the angle of the valve chamber relative to the axis of the ports. The plug has a closed position isolating one port from the other. Rotation of the plug 180.degree. from the closed position in a direction threading the plug outwardly of the chamber, provides substantially full opening of the valve, with the end face of the plug disposed in parallel to the common axis of the ports.
