Abstract: This invention relates to a glass laminate containing an interlayer based on a specified ethylene vinyl acetate-based resin composition, which is particularly suitable for higher temperature applications where polymer creep can be an issue, such as overhead architectural glazing, spandrels and bolted laminate applications, and particularly for locations where the glazing temperature can exceed 50° C., and even 60° C., for an extended period.

Abstract: A multilayer interlayer containing a specified ionomer skin layer and an acoustic damping intermediate layer, and laminate containing such interlayer are provided, wherein the laminate has a desirable combination of sound insulating, flexural strength and optical properties suitable for use in transportation and architectural end uses.

Abstract: The invention describes a polymeric sheet that has at least one layer that comprises an ionomer or ionomer blend that incorporates a partially neutralized alpha, beta-ethylenically unsaturated carboxylic acid component and is useful in glass laminate applications. The ionomer or ionomer blend contains one or more monovalent metal ions in an amount ranging from about 1 to about 60%, preferably about 10 to about 55%, and more preferably about 15 to about 50%, and one or more polyvalent metal ions in an amount ranging from about 40 to about 99%, preferably about 45 to about 90%, and more preferably about 50 to about 85%. This ratio range of monovalent and polyvalent metal neutralization ions provides synergistically greater adhesion to glass than found for either the monovalent or the polyvalent metal neutralization ions alone.

Abstract: A method and apparatus for measuring the bore diameter of a hole as a function of hole depth is disclosed. In one embodiment, the apparatus comprises a diametric probe, for generating first measured bore diameter data along a diametric probe sensitive axis; a foot, for positioning the diametric probe sensitive axis in a plane parallel to the hole; a linear distance probe, coupled to the diametric probe, for generating first measured depth data describing the depth of the diametric probe sensitive axis within the hole; and a data acquisition system, for recording first measured bore diameter data from the diametric probe and first measured depth data from the linear distance probe of an insertion of the diametric probe into the hole.

Abstract: The present invention is an improved polymeric resin composition comprising or consisting essentially of from about 70 wt % to about 79 wt % units derived from ethylene and from about 21 wt % to about 30 wt % units derived from an ?,?-unsaturated carboxylic acid having from 3 to 8 carbons. Resins of the present invention are particularly suitable for preparing transparent laminates useful as glazing elements that provide a greater measure of safety than non-laminated glazing elements. Laminates of the present invention have 3% haze or less without the addition of amines.

Abstract: Apparatus and methods for scanning conoscopic holography measurements are disclosed. In one embodiment, a system includes a conoscopic holography sensor, a beam directing assembly, and a control assembly. The beam directing assembly is adapted to adjustably direct a laser beam from the sensor toward the workpiece, and to direct a reflected light from the workpiece into the sensor. The control assembly controllably adjusts a direction of the laser beam into a desired position on the workpiece. In one particular embodiment, the beam directing assembly includes first and second mirrors coupled to first and second galvanometers for controllably directing the laser beam along first and second axes, respectively. Alternately, the system includes a calibration assembly having a three axis stage for performing calibrations of the laser beam location.

Abstract: The present invention is a PVB interlayer that is plasticized with a single plasticizer and has sound-damping properties. Interlayers of the present invention when used in glass laminates can provide sufficient strength for use as safety glass laminates.

Abstract: The present invention is a direct-point attachment glazing (bolted glass) system (20) comprising: (1) a polymer interlayer (28); (2) at least one sheet of glass (24); (3) at least one receptor for an attachment means; and (4) at least one attachment means, wherein the polymer interlayer (28) is bonded on at least one surface to at least one sheet of glass (24), and wherein at least one receptor (22) is adhesively bonded to the glass by the polymer interlayer (28) in such a way that the receptor (28) is positioned to mechanically accept the attachment means.

Abstract: This invention is a process of preparing a glazing structure that is a glass laminate having enhanced resistance to being pulled from a frame upon being subjected to high positive and/or negative pressure loads. This invention is particularly suitable for architectural structures having windows that can be subjected to the extreme conditions prevalent in a hurricane, bomb-blast event or placed under stress from repeated forceful blows to the laminate.

Abstract: The present invention is a direct-point attachment laminate system comprising: (1) a thermoplastic interlayer; (2) at least one sheet of a rigid structural load-bearing layer (structural layer); (3) at least one receptor means; and (4) at least one attachment means, wherein the thermoplastic interlayer is bonded on at least one surface to at least one sheet of the structural layer, and wherein at least one receptor means is also adhesively bonded to the thermoplastic interlayer and thereby adhesively bonded to the structural layer, wherein the receptor means is positioned to mechanically accept the attachment means, with the further proviso that the attachment means and/or the receptor means are made from materials having a coefficient of expansion that is from about 90% to about 110% of the coefficient of expansion of the structural layer.
