    Abstract: Certain example embodiments of this invention relate to techniques for protecting the pump-out tubes of vacuum insulating glass (VIG) units. More particularly, certain example embodiments relate to techniques for protecting a pump-out tube of a VIG unit by providing a cap around the tube, with the cap and the tube being mechanically separated from one another. In certain example embodiments, the cap and an outer surface of the substrate in which the pump-out tube is located are connected to one another via an adhesive (e.g., a double-sided tape or other adhesive). The mechanical separation or isolation as between the cap and the tube may help protect the potentially fragile glass pump-out tube, in that forces imparted to the cap preferably would be buffered from and generally not transferred to the tube.

  • Patent number: 8298362
    Abstract: The present invention aims to provide a manufacturing method for a PDP which allows even high-definition and ultra-high-definition PDPs to demonstrate an excellent image display capability at improved luminous efficiency, by suppressing variation of a discharge gas composition, and by eliminating an impurity gas in a discharge space effectively. To achieve the aim, deterioration of an absorbent material 39 composed of copper ion-exchanged ZSM-5-type zeolite is prevented, by performing both sealing and evacuation steps for the front substrate 2 and back substrate 9 in a non-oxidizing gas atmosphere. This maintains properties of the absorbent material 39 for absorbing the impurity gas without degradation, even if the absorbent material 39 absorbs a Xe gas in a discharge gas introducing step.

  • Publication number: 20120247063
    Abstract: Vacuum-insulated glass windows include two or more glass panes, and glass-bump spacers formed in a surface of one of the panes. The glass-bump spacers consist of the glass material from the body portion of the glass pane. At least one of the glass panes comprises chemically-strengthened glass. Methods of forming VIG windows include forming the glass-bump spacers by irradiating a glass pane with a focused beam from a laser. Heating effects in the glass cause the glass to locally expand, thereby forming a glass-bump spacer. In embodiments where the glass-bump spacers are formed in a chemically-strengthened glass pane, the glass-bump spacers may be formed before or after the chemical strengthening. A second glass pane is brought into contact with the glass-bump spacers, and the edges sealed. The resulting sealed interior region is evacuated to a pressure of less than one atmosphere.

    Abstract: A process for bonding a vented hollow component includes placing a preformed component with an aircraft skin on a tool surface, with bonding agent applied between the component and the skin. A vacuum bag is sealed about a vent in the preformed component. The vent may be formed through the vacuum bag and the component, or the vent may be preexisting (i.e., an open end of the preformed component or an aperture through the component). The vacuum bag is sealed to the tool surface with a temporary seal or adhesive, to enclose the preformed component and the skin. A vacuum is applied within the bagging material, to compress the preformed component with the aircraft skin, and the bagged assembly is autoclaved to cure the bonding agent. The vent in the preformed component facilitates pressure equalization within and outside of the component to enhance compression against the aircraft skin.

  • Patent number: 7097724
    Abstract: A sash frame is provided having a first mounting surface for a first glazing pane and a second mounting surface for mounting a second glazing pane substantially parallel to the first glazing pane. The first and second mounting surfaces are spaced apart to provide an insulating space between the glazing panes. An evacuation opening is provided in communication with the insulating space. The first glazing pane is adhesively mounted to the first mounting surface and the second glazing pane is adhesively mounted to the second mounting surface. Air is allowed to exhaust through the evacuation opening as the insulating space is formed between the glazing panes. A vacuum is drawn from the evacuation opening to draw the first and second glazing panes closer together after the panes have been mounted on their respective mounting surfaces. Mounting of the glazing panes may also be facilitated using a roll press.

  • Patent number: 7081178
    Abstract: A method of constructing a glass panel which comprises two confronting edge sealed glass sheets, the method comprises the steps of providing a solder glass band around the margin of one surface of each glass sheet, forming, at a first temperature, an hermetic bond between the solder glass band and the associated surface of each glass sheet, positioning the glass sheets in spaced-apart confronting relationship, forming, at a second temperature which is lower than the first temperature, an hermetic seal between the two solder glass bands whilst maintaining the spaced apart relationship between the glass sheets.

  • Patent number: 7063760
    Abstract: A method for laminating glass sheets wherein laminating film is placed over one surface of a first glass sheet and the film is heated with microwave radiation to a bonding temperature. Heated areas of the film are successively pressed to the glass sheet in a continuous manner for purging air from between the film and the first glass sheet and for applying bonding pressure. The pressed film areas are then cooled whereby an appropriate bond is attained between the film and the first glass sheet. Thereafter the first glass sheet with its bonded film is subjected to a partial vacuum and a second glass sheet is positioned on the film and the second glass sheet is pressed to the film. The film is then reheated with microwave radiation to a bonding temperature and thereafter cooled whereby an appropriate bond is obtained between the film and the second glass sheet to provide a glass lamination.

  • Patent number: 6932879
    Abstract: An improved method of weldbonding utilizing inclusion bodies, placed directly between materials to be bonded or included in a weldbonding adhesive. The inclusion bodies maintain a gap between the materials to be welded which provides a gas releasing egress route to disperse the gas and gaseous byproducts produced during welding. This egress route substantially prevents the gases and gaseous byproducts from being expelled through the weld pool and the resultant degradation of the quality of the weld pool, particularly with coated materials, partial penetration welds, and such materials as 6000 series aluminum. The method further comprises an optional step of including a crack-reducing additive, applied either directly to the materials to be welded or included in the adhesive. A laser weldbonding embodiment may use a plurality of phased heat cycles to reduce weld imperfections, and enhance the effects of the adhesive and optional crack-reducing additive.

  • Patent number: 6916392
    Abstract: The invention provides methods of producing and servicing insulating glass units. Methods are provided for reducing the pressure differential on an IG unit, for changing the interior pressure within an IG unit, and for changing the gaseous interior composition within an IG. These methods can be practiced by forming a hole through at least one of the panes of an IG unit, and flowing gas through the hole. One method includes forming a hole through one of the panes of an IG unit, flowing gas through the hole, and sealing the hole with an optically clear sealant (e.g., a transparent resin). A number of methods for producing IG units are also provided. Further, several kits are provided for servicing IG units. There is also provided a method for detecting leaks in an IG unit by flowing an opaque gas into the unit and observing the unit to detect leaks of the opaque gas therefrom.

  • Publication number: 20040142100
    Abstract: A method and apparatus for coating the glass envelope and portions of the end caps of fluorescent light tubes in a continuous and sequential manner with a thermo-plastic material. The coating is applied by a cross head extruder through which the light tubes are sequentially fed. A vacuum applied during the coating process promotes direct and intimate contact between the coating and the light tubes. The end caps may be heated prior to coating to ensure adherence of the coating to the end caps and not to the glass envelope. Post-coating processes include cooling the coating, severing individual light tubes from the chain of sequentially coated light tubes, and readying the coated light tubes for packaging. The method is automatic, with the apparatus being automatically controlled by a control unit.
