A low infrared absorbing lithium glass includes FeO in the range of 0.0005-0.015 wt %, more preferably 0.001-0.010 wt %, and a redox ratio in the range of 0.005-0.15, more preferably in the range of 0.005-010. The glass can be chemically tempered and used to provide a ballistic viewing cover for night vision goggles or scope. A method is provided to change a glass making process from making a high infrared absorbing lithium glass having FeO in the range of 0.02 to 0.04 wt % and a redox ratio in the range of 0.2 to 0.4 to the low infrared absorbing lithium glass by adding additional oxidizers to the batch materials. A second method is provided to change a glass making process from making a low infrared absorbing lithium glass to the high infrared absorbing lithium glass by adding additional reducers to the batch material. In one embodiment of the invention the oxidizer is CeO.sub.2. An embodiment of the invention covers a glass made according to the method.

A laminated glazing unit includes a glass sheet, the border of which is set back relative to that of a structural block, the edge of the glass sheet and the edge of the adhesive interlayer bonding the sheet and the block, the surface of the block protruding relative to the sheet, the edge of the block and a peripheral portion of the free surface of the block being covered by a seal, the laminated glazing being clamped to the mounting structure by a pane retainer, the seal extending in the direction of the pane retainer and/or in the direction of the structure in a rigid protrusion having a small depth and a flexible protrusion having a large depth.

The present invention belongs to the field of shielding mechanics for personal protective equipment and more specifically relates to the external shielding of a transparent glass or armor curved and laminated on its periphery, which has an argon chamber for automobile windows that does not requires modification of door or window frames; since it proposes a new solution with a reinforced flange that is established in the armor and not in the frame of the vehicle, made up of a perimeter steel flange, glass of different sizes, reinforcing polycarbonates and an argon chamber that makes it light, thin, which does not fog up due to temperature changes and blocks external bullet impacts but is permissive to the passage of bullets towards the outside of the vehicle due to internal impact.

Head-up displays, HUD, have been in commercial use for several decades in diverse applications seeking to minimize driver distraction while at the same time dealing with the overload of information available from the various vehicle systems. The disclosure provides an HUD coating glazing that when used in conjunction with a projecting means emitting p-polarization light, results in a bright, high contrast image with substantially no secondary images. The coating of the present disclosure is deposited on at least a portion of the glass surface of the windshield, or any other vehicle glazing, allowing for multiple displays and supporting augmented reality, the coating comprising at least one first dielectric layer being Si-based layer, a functional metallic layer, a second dielectric layer with an index of refraction between 1.4 and 2.0 and at least one third dielectric layer having scratch-resistance and environmentally protective properties.

A laminated glazing includes a first substrate and a second substrate connected to one another via a first polymer interlayer, and optionally a third substrate connected to the second substrate via a second polymer interlayer, the substrates being made of chemically strengthened glass. The glazing includes a solar control coating including at least one functional silver-based metal layer and at least two dielectric coatings, each dielectric coating including at least one dielectric layer, such that each functional metal layer is arranged between two dielectric coatings and a heating coating including a conductive oxide layer located on one face of a substrate that does not include the solar control coating, the solar control coating and the heating coating being located on face 2 or on face 3, each on two different substrates.

The laminated glazing proposed in this invention has an outer glass layer (201) with holes (20) and a thin inner facing glass layer (202) with shorter length dimension whereas the bottom edge (30) does not have holes on it and which does not overlap with the holes (20) in the outer glass layer (201). One or more retention layers (36), comprising reinforcement and adhesive layers, serve to connect the glazing mounting means (32) to both of the glass layers (201, 202) providing a thin laminated glazing with holes (20) that in the event of failure is retained by the mounting means (32).

A glass article according to the present invention includes a glass substrate and a water repellent film provided on the glass substrate and containing an inorganic water repellent component, in which the inorganic water repellent component contains a lanthanoid oxide.

A ballistic unit including a laminated glass panel of 4 to 10 sheets of mineral glass with thicknesses between 4 and 12 mm, with adhesive interlayers of thicknesses between 0.1 and 6 mm, of length between 400 and 2000 mm, width between 150 and 500 mm and thickness between 40 and 100 mm; the unit including through-bores of diameters between 1/10 and of the thickness thereof, the bores are aligned and regularly spaced along three of the four sides of the unit, their centers being at a distance from the side of at least twice their diameters, and the sum of the diameters of the bores on each side does not exceed of the length thereof.

A floor assembly may include an array of display devices facing in an upward direction, and a composite glass floor panel arranged above the array of display devices. The composite glass floor panel may be translucent and include a light diffusion layer.

A laminated glazing for a motor vehicle, particularly a side glazing intended to be slidably mounted in a door of the vehicle, includes at least one outer glass sheet and one inner glass sheet assembled by an interlayer which includes at least one sheet of polymer material, the glazing including at least one part for attaching the glazing provided with at least one attachment hole which has an axis and passes at least through the outer glass sheet, the attachment hole being intended to receive a system for attaching the glazing with a drive device, wherein the glazing includes at least one insert which, including a hole, is housed in a complementary cut-out provided in the interlayer, at the attachment part.
