    Abstract: A glass article including a frame having a frame support surface, a glass sheet having a first major surface and a second major surface in which the second major surface is opposite to the first major surface, and an adhesive bead disposed between the frame support surface and the second major surface. The adhesive bead defines a bead path. The adhesive bead has a cross-section perpendicular to the bead path, and the cross-section includes a width and a height. The height is a maximum dimension perpendicular to the second major surface of the glass sheet, and the width is a maximum dimension parallel to the second major surface of the glass sheet. An aspect ratio of the height to the width is at least 0.6, and the width is 2 mm or less.

    Abstract: A glass container comprises a glass body comprising a first region under a compressive stress extending from a surface of the glass body to a depth of compression and a second region extending from the depth of compression into a thickness of the glass body, the second region being under a tensile stress. The glass container also includes a localized compressive stress region having a localized compressive stress extending from the surface to a localized depth of compression within the body. The localized depth of compression is greater than the depth of compression of the first region. The glass container also includes a crack re-direction region extending in a predetermined propagation direction, wherein the crack re-direction region possesses a higher tensile stress than the tensile stress in the second region in a sub-region of the crack re-direction region, the sub-region extending substantially perpendicular to the predetermined propagation direction.

    Abstract: Disclosed are embodiments of a vacuum chuck. The vacuum chuck includes a forming surface having a first longitudinal end, a second longitudinal end, and a curved region. The first longitudinal end and the second longitudinal end define a longitudinal axis, and the curved region defines a radius of curvature along the longitudinal axis. A plurality of elongate grooves are formed into the forming surface in the curved region. Each elongate groove of the plurality of elongate grooves has a length, a width, and a depth extending into the forming surface. The length of each elongate groove is greater than the width. At least one conduit is configured for connection to a vacuum source and is disposed beneath the forming surface. The at least one conduit extends transversely across the plurality of elongate grooves, and the at least one conduit is in fluid communication with the plurality of elongate grooves.
