FEATURE sulation includes a sealing dam surrounding the cell region of the OLED device to support a cap. The sealing dam provides a sealing region between the edge of the cap and dam in which an adhesive is applied to seal the OLED. The use of the dam is particularly useful for devices to be formed with narrower sealing widths. Patent number: WO 02/21557 Inventors: E.K.M. Guenther, M.D.J. Auch Publication date: 14 March 2002
Inflatable seal Applicants: Tyco Electronics Raychem GmbH, Germany, and Tyco Electronics UK Ltd, UK An inflatable seal for closing an empty elongated duct, or for sealing cables as they pass out through a duct, is formed by welding together two sheets of polymeric laminate material at their peripheries and also at a number of locations over their surfaces. In this way an envelope is produced that has a plurality of generally elongated parallel tubes that are openly linked to each other, giving a contoured outer surface. When the envelope is rolled lengthwise over onto itself, the contouring provides mechanical interlocking, thereby resisting movement of the inflated seal along the duct.

Heat resistant magnetic silicone rubber Applicant: General Electric Co, USA A brush seal includes a brush seal body (formed from a heat-resistant magnetic silicone rubber material) in the form of a channel. Bristles are disposed in the channel of the brush seal body at a cant angle and project from the edges of the body terminating in bristle tips. The brush seal is formed linearly and, in use, is flexed to form an annular seal between adjacent annular sealing components, with the seal carried by one component and the bristle tips engaging the opposite component. The magnetic material of the seal body enables temporary securement of the seal to one of the components, while the seal is adjusted and finally secured in place. Patent number: WO 02/21027 Inventors: Z. Zhuo, W. Tong Publication date: 14 March 2002
Heat seal coating and coated film Applicant: Mitsubishi Polyester Film Llc, USA The subject of this patent is a coated polymer film that has heat sealing properties. The heat seal coating includes a propylene diol copolyester. Preferably, the copolyester is formed from 1,3-propane diol, isophthalic acid and a

sulfomonomer. A method of heat sealing using this coated film is also disclosed. Patent number: WO 02/20263 Inventors: R.G. Posey, C.D. Carlson, J.R. Rounsley Publication date: 14 March 2002
Lamp sealing component Applicant: Meteor Gummiwerke K.H. Bädje GmbH & Co, Germany This invention relates to a component that is designed for sealing a housing and closing plate of a lamp. The sealing section or component is extruded from an elastomer and is inserted into a groove of the housing. The groove has a base. The section has a sealing zone that cooperates with the closing plate and has lateral bearing surfaces, a connecting zone (with a reduced crosssectional surface area) and a base zone that is provided with retaining lips. The base zone has a cylindrical part that cooperates with the groove base to seal the latter. When the sealing section is not in tension, the cylindrical part is completely contained in a retaining groove of the base zone. When the sealing section is inserted into the groove, the retaining lips are pivoted and pressed against ribs on the lateral surfaces of the connecting zone, whereby one part of the cross-sectional surface of the cylindrical part is forced out of the retaining groove and comes into contact with the groove base.

Seal member for ink cartridge Applicant: Unicorn Image Products Co Ltd of Zhuhai, China This patent relates to an ink cartridge for a printer. The ink outlet port of the cartridge is provided with a seal that is used to mate with the print needle and maintain the ink. The seal contains an integrally provided supporting portion that closely fits into the ink outlet port; a seal annular portion, which projects from the supporting portion; a block that cooperates with the annular portion; and a connecting portion, which surrounds the block and the annular portion. The member has good sealing functionality while the ink cartridge is not being used. The connecting portion is broken, when the needle penetrates through it, and separates the block from the sealing annular portion. Since the annular portion fits closely into the needle, the seal member functions well during use. Patent number: WO 02/20270 Inventors: Q. Xiao, Y. Li Publication date: 14 March 2002
Seal ring using a gas curtain Assignee: Brooks Automation Inc, USA A non-contact isolation seal assembly for rotary and linear sealing applications in semiconductor manufacturing automation is described in this patent. The non-contact isolation assembly employs a seal that has an aperture with a shaft which extends through an aperture. A gap region is maintained between the outside surface of the shaft and the aperture of the seal. A gas source is connected to the interior of the gap region whereby gas pressure in the gap region is maintained at a higher pressure than gas pressure surrounding the shaft. The flow of gas and differential pressure prevents fluids, gasses and contaminants from passing through the gap region. This prevents the drive mechanism from becoming contaminated. Patent number: US 6352265 Inventor: T.T. Ha Publication date: 5 March 2002
Aperture seal Assignee: Tyco Electronics Raychem NV, Belgium A seal is provided for sealing an aperture in an object through which extends one or more elongate articles. The seal includes a first support member that has at least one longitudinally extending channel adapted to accommodate and support an elongated article. A second support member is longitudinally spaced from the first support member. The second support member has at least one longitudinally extending channel corresponding to that of the first support member, and a sealing member is positioned between the first and second support members. In this way an elongated article may be accommodated within the longitudinal extending channel of the first support member so as to extend through the corresponding channel on the second support member while deforming the sealing member. Patent number: US 6353186 Inventors: F. Dams, J. Dericjk, D. Roosen, F. Vandeputte Publication date: 5 March 2002
Seal for a liquid chromatography column This patent describes a liquid chromatography seal that is capable of withstanding pressures in excess of 8000 psi to 10 000 psi using an annular ring disposed upon either the seal or the seal seating surface. The annular ring is triangular in cross-section. This cross-section forms three seals. The first seal is the innermost face of the triangular cross-section; the third is the outermost face;
