  • Patent number: 6676786
    Abstract: A method of and apparatus for evacuating a chamber, for example in vacuum glazing, that is enclosed in part by a glass wall that includes an evacuation port. An evacuating head is employed and is arranged to cover the port and a portion of the glass wall that surrounds the port. The evacuating head has a first cavity that communicates with the port and at least one further cavity that surrounds the first cavity.

  • Patent number: 6668974
    Abstract: The invention relates to an acoustic insulating glazing unit. This glazing unit comprises two glass sheets (12, 14) joined together around their periphery by means of an assembly (16) forming a seal (163) and an insert frame (161) which defines, with the two glass sheets, a flat cavity filled with a gas, and a waveguide fastened between the glass sheets, internal to the insert frame. The waveguide consists of at least one straight tubular section (20, 22, 24, 26) placed on the periphery of the gas-filled cavity along one side of the glazing unit, this section being provided with a transverse partition (28) which closes the latter in its length direction, the said partition being placed at a length position along the section which depends on the acoustic mode of the cavity that it is desired to disorganize, this partition defining, on either side of it, two chambers (30, 31) which communicate with the cavity through the ends of the sections.

  • Patent number: 6665995
    Abstract: Two parallel glass panes are separated by a core spacer made of either EPDM rubber or another solid rubber material with a nonheating, centrally positioned, nonstretchable fiberglass cord being embedded therein and extending longitudinally therethrough so that the core spacer is not stretchable. The EPDM rubber formulation is chemically compatible with hot melt butyl which is used as an adhesive between the solid rubber and the glass panes. The fiberglass cord is nonstretchable so that the core spacer does not deform or break apart when the core spacer is either initially manufactured or later placed between the pair of two glass panes. The core spacer and the cord extend around a periphery and go around corners between the panes in an airtight manner to form an insulated assembly. Also, the cord has a diameter no greater than about 10% of a width of the core spacer. A method for manufacturing the insulated assembly is likewise disclosed.

  • Publication number: 20030230045
    Abstract: An insulated glass (IG) assembly for windows which includes an internal lighting system is disclosed. The IG assembly includes two or more panes of glass, a spacer and a strip of light emitting diodes (LEDs). The spacer separates glass panes and provides the hermetic seal for the IG assembly. The spacer extends around the periphery of the glass panes with a portion of its ends overlapping to form a sealed corner joint. The LED light strip includes a plurality of LED lamps connected in series by thin electrical contact wires fixed in a flexible nonconductive substrate. The LED strip is fixed to the spacer and extends around the periphery of the insulated glass unit. The lead wires from the LED light strip pass through the corner joint between the overlapped ends of the spacer. The LED light systems provide dependable illumination but emit relatively little thermal energy. Consequently, the LED light system maintains the thermal insulating properties of an insulated glass unit.

  • Patent number: 6607622
    Abstract: A method for adhering/bonding a frame profile (e.g., weather strip, water seal, spacer, etc.) to a substrate (e.g., glass or plastic substrate) in the context of a vehicle window unit. A frame profile is formed via extrusion so as to include both a polymer profile portion and a selectively activatable interface or adhesive portion. Following extrusion, the frame profile may be stored, cut, trimmed, cure, etc. At some point following extrusion, the interface/adhesive is in a non-activated state, or at least in a state where it is not activated to an extent sufficient to bond/adhere the frame to the substrate. To adhere/bond the frame profile to the substrate, the interface/adhesive portion of the frame profile is activated (e.g., heat activated). Following and/or during heat activation, the frame profile is pressed against the substrate, or vice versa, so that the activated adhesive bonds the polymer profile to the substrate.

    Abstract: A plastic window assembly is adapted to be mounted in an opening defined by a structure. The plastic window assembly is oval-shaped with a decorative plastic window muntin. A plastic frame supports parallel window panes. The window muntin is disposed between the parallel window panes. Flat surfaces of the window muntin have a first edge and a second edge and include a ridge disposed along each of the edges. Marring of the window panes is prevented because the ridge provides for line contact between the window muntin and the window panes. The window muntin may also be integrally molded to a plastic pane disposed between the parallel panes of glass. The plastic pane includes a surface texture that simulates frosted glass. The plastic window assembly includes a plurality of liner panels that extend through the opening from an interior of the structure. The window assembly includes a flange having aperture throughwhich fasteners are inserted to secure the window assembly to the structure.

  • Patent number: 6457294
    Abstract: An insulating glass unit including a first pane of glass, a second pane of glass, and a spacer system. The spacer system includes (i) a spacer positioned between an inner surface of the first pane of glass and an inner surface of the second pane of glass and (ii) a sealant system for adhering the inner surfaces of the glass panes to the spacer. The sealant system includes at least one sealant having (a) at least one thermoplastic hot-melt material having a melt temperature ranging from about 125° F. (51° C.) to about 250° F. (121° C.), and (b) at least one curable material. The sealant, when cured, forms a covalent bond between the spacer and the panes. The sealant has an initial hardness ranging from about 25 Shore A to about 450 Shore A and a post-cure hardness measured about 48 hours thereafter ranging from about 30 Shore A to about 50 Shore A.

  • Patent number: 6436492
    Abstract: A vacuum insulating glass (IG) unit and method of making the same. A plurality of fiber spacers (e.g. glass fibers) are provided between first and second opposing substrates in order to space the substrates from one another and maintain a low pressure space therebetween. The fiber spacers may be randomly distributed in a viewing area of the unit, or distributed in approximately uniform rows and/or columns in different embodiments of the invention. In certain embodiments, the fibers may be substantially transparent to certain wavelengths of visible light to render the IG unit more aesthetically pleasing.

  • Patent number: 6434910
    Abstract: Two glass panes are separated by a so-called core spacer made of either EPDM rubber or another solid rubber material with a centrally positioned fiberglass cord extending longitudinally therethrough for imparting strength to the core spacer. The EPDM rubber formulation is chemically compatible with hot melt butyl which is used as an adhesive between the solid rubber and the glass panes. The fiberglass cord is nonstretchable so that the core spacer does not deform or break apart when the core spacer is either initially manufactured or later placed between the two glass panes.
