Abstract: While a first coating gun 405 is being moved along a peripheral edge portion 100a of one surface of a multilayer glass panel 100 horizontally placed on a first worktable 20, the first coating gun 405 discharges a molding material to coat the peripheral edge portion 100a with the molding material over its entire length, molding a glazing gasket 110 thereon. An inverting mechanism 60 inverts the multilayer glass panel 100 with the molded glazing gasket 110 such that the other surface of the multilayer glass panel 100 faces upwardly. Then, a second coating gun 505 is moved along a peripheral edge portion 100b of the other surface of the multilayer glass panel 100, which is horizontally placed on a second worktable 30, and simultaneously discharges a molding material to coat the peripheral edge portion 100b with the molding material over its entire length, molding a glazing gasket 110 thereon.

Abstract: A sealing device and method are described herein that can be used to manufacture a hermetically sealed glass package. In one embodiment, the hermetically sealed glass package is suitable to protect thin film devices which are sensitive to the ambient environment (e.g., oxygen, moisture).

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.

Abstract: A method and apparatus for press sealing a tubular quartz arc tube body section about a ribbon-type metallic seal. The method includes applying different intensities of heat to the quartz arc tube body section to be pressed in such a manner that four portions of the quartz arc tube body section which are located within diametrically opposed quadrant sections are heated to a higher softened-state temperature than those portions of the heated quartz arc tube body which are positioned intermediate the higher-heated quartz arc tube body portions, with the higher-heated quartz arc tube body portions collapsing somewhat due to the surface tension of the softened quartz. Utilizing this method results in an improved press seal.

Abstract: In a reed switch manufacturing machine the closed glass-sealing chamber is modified so that inert gas introduced during fusion of the glass envelope is directed onto the back of gold-plated reflectors in the chamber. This enhances the life of the reflectors resulting in an improved product quality and product yield.

Abstract: In the production of a glass vessel (such as a goblet) comprising a receptacle part (e.g. a goblet bowl) and a stand part (e.g. a stem with a base plate), the receptacle part is formed by pressing in successive moulds carried by a rotary table and the stand part is formed by injection moulding, being simultaneously united to the receptacle part. In carrying the invention into effect the mould for the receptacle part is charged from a feeder in free drop fall; the table is then rotated to bring the pressed receptacle part into register with an injection mould for the stand part, and an injection device, of which the injection mould forms part, is charged from the same feeder by way of a drop guide channel.

Abstract: A collector of solar energy comprises an array of contiguous transparent blocks, arranged in one or more layers or tiers, resting on a thermally conductive supporting plate which overlies a system of conduits for the circulation of a heat-carrying fluid such as water. Each block consists of a thin-walled hollow glass body of generally prismatic shape with a broad concave undersurface which, in the case of the lowest tier, makes only line contact with its supporting surface and is largely separated from that surface by an intervening dead-air space minimizing conductive heat transfer therebetween. A nipple at one end face, used for the blowing of the glass bodies, may be received in a complementary recess of a juxtaposed end face of an adjoining body.

Abstract: A vapor shield supporting ring is attached to the envelope of a vacuum device. The supporting ring is embedded in the inner wall of the envelope and extends into the interior of such envelope. A welding flange is mounted on the interior portion of the ring. The ring does not extend to the exterior wall of the envelope. To embed the ring in the envelope, the ring is suspended by a holding means such as a magnet, which is placed into the desired position within a centrifugal mold. The molten glass is poured into the mold and the mold is spun, thereby flowing the glass along the walls and surrounding the outer portion of the supporting ring. When the glass solidifies, the supporting ring is firmly embedded in the wall of the envelope.

Abstract: Stemmed glassware is produced by a method and apparatus in which the stem is formed separately and is subsequently joined to the cup at the final phase of the blowing operation of the cup glass. In the apparatus a first rotatable platen having cup molds is provided for blowing of the cups and a second rotatable platen having stem molds is provided for forming the stems. A drop of glass for producing the stems is dropped through a very short distance of about 20 to 40 mm. to prevent excessive cooling of the glass drop and to assist in centering the glass drop in longitudinally divided stem molds. A ring centers the mold halves of the stem molds and a surface on the ring molds a part of the stem base. The second platen rotates the stem molds through a pressing station at which the glass drop is pressed to form the stem to a transfer station at which a transfer means transfers the finished stems from the second rotatable platen and attaches the stems to the cups on the first rotatable platen.
