  • Publication number: 20090199719
    Abstract: The invention discloses a glass vessel for a beverage-making machine, which glass vessel is at least partly of double-walled design. In a first refinement, an inner part (1) projects beyond an outer part (2) which partly surrounds said inner part, with the result that a double-walled lower region (100) and a single-walled upper region (101) with a pouring region (13) arranged therein are provided. In another refinement, the inner part and outer part are connected at their upper edge, and the pouring region is of double-walled design. The invention also specifies a method for producing the vessel.

  • Publication number: 20080209945
    Abstract: Cremated ashes or other carbon containing artifacts are displayed between layers of glass. The method of preparation of the display includes taking a layer of glass, preferably dichroic glass, and sprinkling a layer of glass frit along with the artifact onto the first glass layer. The sprinkled layer is covered with a second layer of glass, the whole assembly being fused at a temperature of about 1700 degrees Fahrenheit or 927 degrees Celsius. An optional third layer above the second layer of glass adds apparent depth and provides a layer space for fusing in additional artwork or other aesthetics and decorations.

  • Patent number: 7251959
    Abstract: A neutralization system for controlling the pH of the washwater used to clean and maintain polyacrylic bound glass forming equipment. The neutralization system introduces a base solution to a washwater solution when the pH of the washwater solution contained in a closed loop washwater recovery system falls below about 8.5, thereby substantially reducing the corrosion rate of the components of the equipment associated with acidic polyacrylic acid binder, maleic acid cobinder or maleic anhydride cobinder and washwater solution. A closed-loop hoodwall washwater recovery system may also be introduced in addition to the neutralization system that allows for the recovery and reuse of polyacrylic acid binder and maleic acid cobinder or maleic anhydride cobinder with a minimal amount of base solution, thereby minimizing degradation of insulation properties of polyacylic acid bound glass fiber products.

  • Patent number: 7137546
    Abstract: Tubular silicon members advantageously formed by extrusion from a silicon melt or by fixing together silicon staves in a barrel shape. A silicon-based wafer support tower is particularly useful for batch-mode thermal chemical vapor deposition and other high-temperature processes, especially reflow of silicate glass at above 1200° C. The surfaces of the silicon tower are bead blasted to introduce sub-surface damage, which produces pits and cracks in the surface, which anchor subsequently deposited layer of, for example, silicon nitride, thereby inhibiting peeling of the nitride film. Wafer support portions of the tower are preferably composed of virgin polysilicon. The invention can be applied to other silicon parts in a deposition or other substrate processing reactor, such as tubular sleeves and reactor walls. The tower parts are preferably pre-coated with silicon nitride or polysilicon prior to chemical vapor deposition of these materials, or with silicon nitride prior to reflow of silica.

  • Patent number: 7083694
    Abstract: A method of joining two silicon members, the adhesive used for the method, and the joined product, especially a silicon tower for supporting multiple silicon wafers. A flowable adhesive is prepared comprising silicon particles of size less than 100 ?m and preferably less than 100 nm and a silica bridging agent, such as a spin-on glass. Nano-silicon crystallites of about 20 nm size may be formed by CVD. Larger particles may be milled from virgin polysilicon. If necessary, a retardant such as a heavy, preferably water-insoluble alcohol such as terpineol is added to slow setting of the adhesive at room temperature. The mixture is applied to the joining areas. The silicon parts are assembled and annealed at a temperature sufficient to link the silica, preferably at 900° C. to 1100° C. for nano-silicon but higher for milled silicon.

  • Publication number: 20040172975
    Abstract: In joining the end portions of belt-shaped glass sheets, the end portions of belt-shaped glass sheets are thermally softened after the end portions are located so that they overlap each other within the range of the glass sheet width. Lap portions of the thermally softened end portions are clamped at least once from both sides in the thickness direction of the belt-shaped glass sheets by means of pressure dies. Thus, the lap portions are joined together to be adjusted to the thickness of the belt-shaped glass sheets.

  • Patent number: 6668588
    Abstract: A method for molding a chalcogenide glass lens includes providing a mold. A preformed lens of chalcogenide glass is placed within the mold. The lens has a top surface and a bottom surface. An amount of chalcogenide glass is deposited within the mold and on the top surface of the preformed lens. The mold is heated, such that the chalcogenide glass on the top surface of the preformed lens softens, melts, and bonds to the top surface of the preformed lens. A lens surface is formed in the melted chalcogenide glass to form a molded lens which is bonded to the top surface of the preformed lens. The molded lens and preformed lens assembly is then removed from the mold.
