An optical fiber coating die assembly is provided. The optical fiber coating die assembly includes a housing defining a guide chamber having an inlet for receiving optical fiber and an outlet, a guide die located at the outlet of the guide chamber, and a sizing die. The optical fiber coating die assembly also includes a coating applicator disposed between the guide die and the sizing die, and a tube operatively coupled to the inlet of the guide chamber and axially aligned with the chamber to receive the optical fiber fed into the guide chamber and provide a barrier to air flow.

A surface treatment applied to a glass which reduces breakability of the glass includes a substrate and a toughened layer formed thereon. The toughened layer of the disclosure is formed on at least one surface of the substrate. The toughened layer is an optical-grade nano resin film which has no significant effect on the transparency or color of the substrate. The disclosure further provides a method for applying the toughened layer on the glass.

Disclosed are non-porous inorganic frit compositions, which permit the decoration of ion-exchangeable glass-based substrates before the ion exchange chemical strengthening processes. When fired, the non-porous inorganic frit compositions comprise a crystallized phase and/or a T greater than about 80 C. Also disclosed are strengthened glass-based substrates having one or more non-porous inorganic layers, glass-based articles comprising strengthened glass-based substrates having one or more non-porous inorganic layers, and methods of making the same.

A system and method for forming a membrane on an immersion tube for an electrochemical sensor comprise a step of providing a first immersion tube having a first opening and a second opening, and an apparatus having a melting system, a positioning system, an imaging apparatus, a pressure supplier, a control system. The melting system includes a heating means and a crucible containing a melt. The positioning system is suitable to move the first immersion tube relative to the crucible, such that the first opening of the first immersion tube is immersed in the melt. The imaging apparatus includes a camera, which is temperature sensitive and is arranged such that it can see the melt. The pressure supplier is connected air tightly with the first opening of the first immersion tube. The control system is connected with the melting system, the positioning system, the imaging apparatus and the pressure supplier.

A curable glass coating composition including 5-70 wt % aliphatic polycarbonate diol, 5-60 wt % crosslinker, 1-20 wt % extender, 4-20 wt % fatty alcohol, and 2-30 wt % crystalline or amorphous powder filler material, and optionally 2-20 wt % aliphatic polyester polyol and 2-20 wt % cycloaliphatic epoxy. The coating composition can be applied to a glass substrate and cured to form a decorative cured polyurethane coating layer on the substrate that has improved caustic and UV resistance.

A method for repairing surface smoothness of heat-bent glass includes: providing a fluid which is transparent and solid at room temperature on an inner side of a heat-bent clear glass used for manufacturing a screen protector of an electronic device; by utilizing a mold having a pattern corresponding to the surface smoothness of a screen of the electronic device, pressing the inner side of the heat-bent clear glass and at the same time processing the fluid on the inner side of the heat-bent clear glass through a reverse mold replication process so that the fluid fill a curved and uneven surface of the inner side of the heat-bent clear glass; and curing the fluid so that the inner surface of the heat-bent clear glass has a curvature and smoothness that match the curvature and smoothness of the screen of the electronic device.

A method of manufacturing an optical fiber wire includes applying ultraviolet curable resin onto the outer periphery of a traveling optical fiber, cooling the ultraviolet curable resin applied to the optical fiber using first cooled inert gas, and curing the ultraviolet curable resin by radiating ultraviolet rays on the ultraviolet curable resin that is cooled by the first cooled inert gas through an ultraviolet transparent tube.
