    Abstract: A method of manufacturing a sheet of glass comprises: (a) forming a vertically oriented ribbon of glass that moves downward as a function of time, the ribbon of glass having a first primary surface and a second primary surface that face in generally opposite directions and a core disposed between the first and second primary surfaces; (b) as the ribbon of glass moves downward, passing the ribbon of glass adjacent to a first raised temperature zone liquefies the first primary surface while a temperature of the core remains below a softening temperature; and (c) after the ribbon of glass moves below the first raised temperature zone, separating a sheet of glass from the ribbon of glass. Passing the ribbon of glass adjacent the first raised temperature zone reduces total thickness variation, surface roughness, and other surface defects of the ribbon of glass.

    Abstract: A Substrate coating apparatus can include a container including a reservoir and an adjustable dam defining an adjustable depth of the reservoir. The apparatus can further include a roller rotatably mounted relative to the container. A portion of an outer periphery of the roller can be disposed within the adjustable depth of the reservoir. A method of coating a substrate can include filling a reservoir of a container with a liquid and contacting a portion of an outer periphery of a roller with the liquid at a contact angle. The method can further include changing an elevation of a free surface of the liquid within the reservoir to change the contact angle. The method can still include rotating the roller about a rotation axis to transfer liquid from the reservoir to a major surface of the substrate.

    Abstract: A system (100) for manufacturing an extrudate (10), such as a honeycomb body, is provided. The system comprises an extruder (102). The extruder is configured to form an extrudate from a wet mixture, such as a ceramic forming mixture. The system further comprises a radiative heat assembly (104). The radiative heat assembly is configured to heat the extrudate. The radiative heat assembly comprises one or more IR light sources (112). The one or more IR light sources are arranged as one or more rings around the extrudate. The system further comprises a differential pressure assembly (108). The differential pressure assembly is configured to remove at least a portion of water vapor from around the extrudate. The differential pressure assembly can direct an air flow out of a chamber (136) formed by a housing (132) surrounding the radiative heat assembly. Alternatively, the differential pressure assembly can direct an air flow into the chamber.

    Abstract: A liquid lens can include a first substrate with an interior recess. A second substrate with a bore can be bonded to the first substrate, whereby the interior recess of the first substrate and the bore of the second substrate cooperatively define at least a portion of a cavity of the liquid lens. A first liquid and a second liquid can be disposed in the cavity. A variable interface can be disposed between the first liquid and the second liquid, thereby forming a variable lens. The interior recess of the first substrate can be positioned outside of a sidewall projection of a sidewall surface of the cavity through the first substrate.
