Abstract: A novel edge design for a laminated electrochromic device containing an ion-conducting material layer prone to moisture gain or loss disposed between first and second substrates is disclosed. The device is characterized by a continuous nub on its circumferential edge which is aligned with the ion-conducting material interface between the substrates forming the device. The nub can be used to interlock with a peripheral edge seal.

Abstract: A device and method for forming a composite from a pair of parts via suspension lamination is disclosed. The device bonds members with opposed mating surfaces and has a base and a vertical column mounted on the base. The vertical column supports a vertical cylinder. A vertically adjustable head assembly for holding an upper part is located at the lower end of the vertical cylinder and is operatively connected to a drive motor at the upper end of the vertical cylinder. A vacuum generator generates a negative pressure to hold the upper part on the head assembly. A nest member is located below and coaxially with the head assembly for supporting a lower part. The upper and lower parts are optionally laterally aligned via an alignment means and a curing medium is provided to the aligned parts to cure an adhesive composition which is spread over the opposed mating surfaces of the parts to form a composite of the parts. Curing occurs while the lower part is suspended from the upper part via surface tension.

Abstract: Organic ophthalmic articles are photochromic and have high indices of refraction.

Abstract: An accumulator for storing rows of articles thereon includes a frame having upper and lower shafts rotatably supported thereon. A plurality of sprockets are mounted on each of the upper and lower shafts for rotation therewith. Each of the sprockets defines a radius. An electric motor is provided for selectively rotating the shafts and the sprockets mounted thereon. A plurality of roller chains are mounted on associated pairs of the upper and lower sprockets for movement when the shafts and sprockets are rotated. Each of the roller chains includes a plurality of spaced apart pins. A plurality of link are carried on each of the roller chains for movement therewith. Each of the links has a pair of apertures formed therethrough and a pair of arcuate slots formed therethrough. The apertures and the slots having respective first edges which define a straight line and respective second edges which define a radius.

Abstract: An electrically heatable windshield with a hidden bus bar configuration. A border of opaque ceramic material, preferably a lead borosilicate enamel, is bonded to an interior surface of the transparency about its periphery. Opposing electroconductive bus bars, preferably a low frit content silver-containing ceramic material, are bonded to the ceramic material so that the entire inner edge of the bus bar overlays a portion of the ceramic material and is spaced from the inner edge of the border, providing an intermediate portion of the border between the bus bars and transparency surface that is not covered by the bus bars. An electro-conductive coating is applied to the transparency to interconnect the bus bars and covers to the inner surface of the transparency, the bus bars and the intermediate portion of the ceramic material border so that electric current flowing between the bus bars must flow through the portion of the coating that covers the intermediate portion of the border.

Abstract: Ophthalmic lenses and lens blanks having high refractive index and high heat distortion temperature are produced by polymerizing a polymerizable, homogeneous composition comprising epichalcogen resin, aliphatic polythiol, and cyclic anhydride.

Abstract: Phenolphthaleinic bis(acrylate), phenolphthaleinic bis(methacrylate), and phenolphthaleinic (acrylate) (methacrylate) may be polymerized to form polymerizates especially useful for lenses and lens blanks.

Abstract: Thermal energy from quartz lamp heaters are used to fire ceramic enamel material onto a glass substrate while minimizing any increase in the temperature of the glass.

Abstract: A low shear modulus thermoplastic polyurethane useful in laminating rigid plies with different coefficients of thermal expansion without warpage is disclosed, along with laminates comprising said low modulus interlayer.

Abstract: A method is disclosed for casting a colorless, single phase liquid reaction mixture comprising an aliphatic diisocyanate and a polyester polyol against a rigid transparent plastic and curing at a sufficiently rapid rate at temperatures of about 175.degree. to 275.degree. F. (about 79.degree. to 135.degree. C.) to form a relatively soft, resilient, abrasion resistant branched polyurethane coating without warpage or deterioration of the rigid plastic. The polyesterurethane coatings disclosed are characterized by durometer values at 70.degree. F. between Shore A 50 and Shore D 80, and molecular weights between branch points between 1000 and 13,000.

Abstract: A method for obtaining improved release of a polymer from a contacting surface by incorporating a reactive internal release agent in the polymer reaction mixture is disclosed.

Abstract: A method for applying a thin abrasion resistant polyurethane coating while minimizing exposure to volatile free isocyanate is disclosed. The method involves forming a hydroxy-terminated prepolymer which is subsequently crosslinked using a relatively non-volatile triisocyanate, and applying the material by flow coating or dip coating techniques, rather than spraying, in order to minimize volatilization.

Abstract: A method for improving the pot life of polyurethane reaction mixtures by solubilizing the polyol component in the isocyanate to lower the required mixing temperature is disclosed.

Abstract: An improved and laminated antenna window for vehicles and the like in which antenna wire is embedded in interlayer material and extends out of a surface of the interlayer material into a notched area for attachment to an electroconductive element adapted to be coupled to a radio receiver. A thin layer of a plastic material having a lower deformation temperature than the interlayer material is used in the vicinity of the notched portion to provide a barrier against fluid penetration between the layers of the assembly to be laminated, thereby insuring a product that is acceptable to the customer.
