A glass interleavant particle composition for location between adjacent stacked glass sheets. The composition includes a) inorganic interleavant particles and b) polymeric adhesion promoter particles in which the inorganic particles are solid up to at least 100 C. have a compressive strength of at least 3 MPa and have a volumetric mass density less than 7.5 g/cm3 at 25 C.

The invention relates to use of selected materials in systems for heat treatment, various forms of such material, related systems and methods for determining such materials. In particular the invention relates to the use of a cover of analumina-chromium alloy material with a Cr content of more than 5 w % (percent by weight) for one or more parts within a system suited for heat treatment.

A mold with a multi-layer coating is disclosed. The mold may include a mold body having an outer surface and a multi-layer coating disposed on the outer surface. The multi-layer coating may include a diffusion barrier layer disposed on the outer surface of the mold body and an intermetallic layer disposed on the diffusion barrier layer, wherein the intermetallic layer comprises Ti, Al, and an additional metal selected from the group consisting of Zr, Ta, Nb, Y, Mo, Hf, and combinations thereof. The diffusion barrier layer may restrict diffusion of metal from the mold body to the intermetallic layer.

A glass sheet used in the making of an aircraft windshield is shaped using the cut-to-size method instead of the out-after-bend method. In a preferred aspect of the invention the cut-to-size method is practiced using a bending iron having a sheet shaping rail having a stationary shaping rail portion mounted on a support member and an articulating shaping rail portion pivotally mounted on the support member for movement from a non-shaping position to a shaping position.

A cover for a radar sensor for motor vehicles, which has a wall provided with a three-dimensional relief structure, in which the wall including the relief structure is made of deep-drawn glass.

Disclosed are apparatuses for shaping a glass structure, the apparatuses having a plurality of rib members, each rib member comprising at least one void and at least one shaping edge; and at least one support member. The apparatuses can further comprise a shaping member and/or a guide member and/or a shaping groove. Also disclosed herein are methods for shaping a glass structure, the methods comprising positioning the glass structure on a shaping apparatus and heating the glass structure to shape the glass structure.

A frame for supporting a sheet of glass, referred to as a suction frame, includes a contact path for receiving the periphery of the underside face of the sheet of glass, and includes a suction system able to apply suction to the underside face of the sheet in order to enhance the retention of the sheet by the frame. This frame may form part of a device for the hot-bending of the sheet and convey the sheet with high acceleration or deceleration through a heating enclosure for the purposes of the hot-bending of the sheet.

A bending station for a bending device, includes two bending molds, a pressing frame arranged to adapt to the glass sheet and to press it against an upper mold, the upper mold including a molding face, the area of which, defined by projecting the contour of the upper mold onto a horizontal plane, is greater than the area defined by projecting the outer contour of the pressing frame and the glass sheet onto the same horizontal plane, the pressing frame including a pressing ring having a continuous surface, the upper mold including a flexible sheet associated with an upper series of translational elements, wherein the upper mold is able to deform under the effect of the translational elements of the upper series in order to obtain a deflection value varying by at least 5 mm.
