Publication number: 20130074445Abstract: 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).

Patent number: 8298362Abstract: 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.Type: GrantFiled: February 25, 2010Date of Patent: October 30, 2012Assignee: Panasonic CorporationInventors: Masahiro Sakai, Keisuke Okada, Yayoi Okui

Patent number: 7063760Abstract: 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.Type: GrantFiled: March 17, 2004Date of Patent: June 20, 2006Assignee: Gyrotron Technology, Inc.Inventors: Vladislav Sklyarevich, Mykhaylo Shevelev

Patent number: 6932879Abstract: 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.Type: GrantFiled: August 13, 2002Date of Patent: August 23, 2005Assignee: Edison Welding InstituteInventors: Kevin J. Ely, Timothy M. Frech, George W. Ritter

Patent number: 6916392Abstract: 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.Type: GrantFiled: April 9, 2002Date of Patent: July 12, 2005Assignee: Cardinal IG CompanyInventors: Paul Trpkovski, Bernard J. Herron

Patent number: 6836613Abstract: A method of creating uniform adhesive layers in a planar optical display is disclosed. The method includes providing an adhesive reservoir, providing at least two optical panels, placing spacers between the optical panels, thereby forming a stack of optical panels having at least one uniform gap between adjacent ones of the optical panels, placing the stack into a panel reservoir having a height and a width, which panel reservoir is connected to the adhesive reservoir by a fluid path, and injecting adhesive from the adhesive reservoir through the fluid path into the bottom of the panel reservoir until each uniform gap is filled. A method of producing a black cladding layer having small particulate size for use in a planar optical display is also disclosed. The method includes providing black pigment having a fine particulate size of approximately 0.Type: GrantFiled: December 24, 2002Date of Patent: December 28, 2004Assignee: Brookhaven Science AssociatesInventors: Leonard DeSanto, Calvin Brewster

Publication number: 20040142100Abstract: 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.Type: ApplicationFiled: November 14, 2003Publication date: July 22, 2004Applicant: Shat-R-Shield, Inc.Inventors: Robert J. Nolan, Mark Cannon
