Abstract: The invention relates to security glass laminates having high strength and impact resistance. The laminates consist of a pane of glass sheets with an ionomer interlayer. The ionomer consists of at least 17% by weight of acrylic acid groups which have been neutralized with a lithium salt.

Abstract: The invention relates to fire and impact resistant windows and building structures which contain a window composed of a specific order of layers containing a novel fire resistant layer. The invention further pertains to coating compositions for use with structures containing the windows.

Abstract: The present invention relates to optically clear fire resistant and impact resistant windows having at least one air gap and at least one fire resistant layer. Optionally there is also an anti-spall layer.

Abstract: There is provided a composition and a method for forming fire resistant panes containing borate-phosphate anions and the window pane and window assemblies prepared therefrom.

Abstract: The disclosure defined by this invention provides a method for extruding thermoplastic polymers which includes the step of creating high pressure steam in the extruding apparatus so as to prevent scorching and to solubilize contaminants. The method can be used in a neutralization step of ionomers in an extrusion process to obtain an extrudate having good light transmission and improved impact resistance.

Abstract: A container, or keg, for storing, shipping, and dispensing a bulk quantity of a fluid, for example, beer or like malt beverage, is provided. The container/keg includes a flaccid bag (56) for containing the fluid and a substantially rigid, pressure-tight, plastic vessel (10) within which the bag (56) is contained. The bag (56) has a mouth (58) secured with a locking ring or the like to an opening in the vessel (10) via which the mouth (58) is accessible externally of the vessel (10) for purposes of filling the bag (56) with the fluid and/or dispensing the fluid from the bag (56). Preferably, the shape of the vessel (10) permits it to be efficiently stacked and shipped when in a full or empty condition. Methods for assembling, filling and shipping kegs are also provided.

Abstract: A glazing unit comprising at least one monolithic glazing element bonded to at least one layer of a polymer having embedded therein at least one element of a fastening means adapted for mounting to a support structure. This construction provides and integrated connecting arrangement for the mechanical fastening of monolithic glazing units to a support structure to obtain a glazing assembly. A plurality of monolithic glazing units form glazing assemblies which when fixed in a planar array define a continuous smooth surface useful as exterior glazing facades. A clear gain is made, according to the invention is the simplicity of the installation of glass glazing facades to provide increased use in architectural designs. The invention is applicable to any glazing unit whether single, laminated, and/or multiple glazing elements are used.

Abstract: The present inventions teaches an optically transparent film or sheet of an extruded acrylic copolymer or terpolymer and polyethylene having a melting point of less than 275° F. and a haze not more than 5%. The resin film can be used alone or in a lamination with other polymers or glass so that the combination has a haze less than 6%.

Abstract: The present inventions teaches an optically transparent film or sheet which is greater than or equal to 0.5 mm in thickness and includes an extrudable ionomer resin which comprises a carboxylic acid polymer and which is essentially free of amines. The ionomer resin film can be used alone or in a lamination with polycarbonate or glass. In certain embodiments, it is preferable to partially or fully neutralize the acid polymer with a metal cation.

Abstract: A fire resistant and impact resistant transparent laminate comprising at least two spaced parallel sheets of transparent material selected from the group consisting of ceramic glass and polymeric material, at least one optically transparent fluorocarbon polymer modified with polar groups, at least one optically transparent glass or resinous inner layer between said parallel sheets, and at least one layer of an optically transparent intumescent gel on at least one side of said inner layer.
