Disclosed herein are embodiments of a borosilicate glass composition as may be useful for windshield and other applications in particular due to unique fracture behavior.

A projection assembly for a head-up display (HUD) includes a windshield, including an outer and inner pane joined to one another via a thermoplastic intermediate layer, and having an HUD region; and a projector directed at the HUD region. The radiation of the projector is predominantly p-polarised, and the windshield is provided with a reflective coating, which is suitable for reflecting p-polarised radiation. The reflective coating has exactly one electrically conductive layer and arranged one above and one below the electrically conductive layer are two dielectric layer sequences, each including n low-optical-refraction layers having an index of refraction less than 1.8 and (n+1) high-optical-refraction layers having an index of refraction greater than 1.8, arranged alternatingly in each case, wherein n is an integer greater than or equal to 1.

A laminated glass capable of producing an observable pattern when edge-illuminated contains two sheets of glass adhered by an adhesive film of at least one film B containing a polyvinyl acetal PB and at least one plasticizer WB; and at least one film A or an area thereof containing a polyvinyl acetal PA and optionally at least one plasticizer WA, wherein the refractive indices of film A and film B differ by at least 0.0002.

A laminated glass, includes an outer pane, an inner pane, at least two lamination layers arranged between the outer pane and the inner pane, and at least one design element, wherein the design element is formed on a partial region of a pane side of the outer pane or the inner pane from a pictorial black print having one or a plurality of unprinted regions, and an opaque, non-black underlay is arranged between the two lamination layers, which underlay is placed underneath the unprinted region(s) of the design element. The laminated glass has a design element with good contrast and good visibility and is suitable in particular as a vehicle window.

Provided is an interlayer film for laminated glass which is excellent in sound insulation property and has improved sound insulation performance not only in a coincidence region but also in a mass-dominated region. The interlayer film for laminated glass includes a sound insulating layer which is formed from a composition (A) containing at least one resin (a1) selected from a thermoplastic resin and a thermosetting resin, wherein a tan δ obtained when a dynamic viscoelasticity of a sheet, which is obtained by molding the composition (A) to have a thickness of 0.8 mm, is measured at a frequency of 0.3 Hz in a tension mode has a maximal value at a temperature T.sub.A (° C.), T.sub.A (° C.) is in a range of −50 to 50° C., and the tan δ at T.sub.A (° C.) is 2.5 or more.

The invention relates to improved methods and implementation of reliably manufacturing laminated solar panel products having one or more axis of curvature, wherein at least one solar cell also has one or more axis of curvature, in a manufacturing plant, the manufacturing plant being capable of continuous, optimized operation. A substrate and a superstrate having a doubly-curved geometry may be assembled with a core disposed therebetween, the core comprising a solar cell array including at least one solar cell. During the lamination process, the plant substantially eliminates cracking of the at least one solar cell of the solar array through controlled and uniform application of lamination pressure and temperature that applies uniform local pressure simultaneously to each cell, resulting in a durable and reliable product. The invention further relates to a plant and/or facility having efficient, effective, and repeatable results relating to such methods.
