The present invention provides high security polycarbonate laminates integrated with insulated glazing units (IGU) to produce high security windows. The laminate comprises at least nine layers, in the following order: (i) an insulated glazing unit; (ii) a thermoplastic polyurethane; (iii) a polycarbonate; (iv) a thermoplastic polyurethane; (v) a polycarbonate; (vi) a thermoplastic polyurethane; (vii) a glass; (viii) a thermoplastic polyurethane; and (ix) a polycarbonate. A frame may surround and overbite the laminate. An array of framed laminates may be arranged such that one framed laminate may be removed, without removing an adjacent laminate.

High security polycarbonate laminate windows with insulated glazing units

The present invention provides a bi-active method of mounting a monolithic polycarbonate sheet or a laminate in a semi-rigid metallic framing system along two parallel sides of a rectangular shaped sheet or laminate with the two shorter parallel sides being unconstrained. In the case of a square shaped sheet, two parallel sides are supported in the semi-rigid frame, and the other two parallel sides are unconstrained. The semi-rigid frame utilizes cylindrically shaped hardware (i.e., bolts, rivets, studs, etc.) to hold the sheet or laminate. The semi-rigid frame is designed, via section and material properties, to flex and hinge about fixed mounting points along the length of the frame.

High-energy impact absorbing polycarbonate mounting method

The present invention provides a lightweight blast-mitigating polycarbonate laminate system comprising at least one polycarbonate sheet, a portion of which is laminated to a glass layer having a thickness between 0.25 times and less than 1 times the thickness of the polycarbonate sheet. The laminate system may further include fasteners to attach the system to a building, positioned to prevent the laminate system from breaking or detaching in case of a blast event.

Lightweight blast-mitigating polycarbonate-based laminate system

The present invention provides structural insulated panels which may afford protection from blast and ballistics events. The inventive structural insulated panel comprises a metal sheet, a polyurethane or polyisocyanurate foam and a polycarbonate sheet, film or laminate. Due to the materials of their construction, the inventive panels are light weight and a plurality of such panels may be quickly and easily assembled into sturdy, insulated, temporary or permanent shelters for protection in a variety of situations and environments.

Ballistic-resistant structural insulated panels

The present invention provides a rapid deployment cover system comprising a polycarbonate laminate or a glass-clad polycarbonate laminate in combination with a versatile and cushioned mounting system to yield a highly durable cover which provides protection from forced-entry, blast, ballistics and/or extreme storms in a wide range of climates.

Polycarbonate based rapid deployment cover system

The present invention provides an energy absorber for a blast barrier system comprising a substantially tubular member extending longitudinally along an axis from a first end portion to a second end portion, each of the first end portion and the second end portion having a substantially similar geometric, profile, wherein the energy absorber collapses under a predetermined load when compressed by a residual blast force. The energy absorber of the present invention may help minimize damage to people and structures by further dissipating force from a blast in a blast barrier system.

A process for endowing a polymeric article with a surface layer of an ion-conducting polymer to yield electrical surface resistivity sufficiently low for electrostatic discharge applications is provided. The polymeric article contains one or more immobilized, polymeric components having amine functional groups. The presence of the ion-conducting polymer in the surface layer lowers the surface electrical resistivity into the range suitable for electrostatic discharge applications, between about 1&#xd7;10and about 1&#xd7;10&#x3a9;/&#x25a1;. Plastic electrostatic dissipation materials produced by the inventive process may find use in the optical, electronics, automotive, entertainment, sporting goods, and medical sectors.

A process for making a colored article of manufacture is disclosed. Accordingly an article of manufacture is first prepared of a material selected from the group consisting of metal, wood, glass, ceramic, masonry and polymeric materials. A polymeric coating (superstrate) is then applied to at least a portion of the surface of the article. At least a portion of the superstrate is brought into contact with a material system that contains (i) water, (ii) a carrier, (iii) a dye and (iv) a diol, under conditions calculated to bring about diffusion of said dye into said superstrate.

Colored article of manufacture and a process for its preparation

A process and an apparatus for treating large articles to impart color or performance enhancing additives to the article in which a treatment system which includes: (i) a coloring solution and/or a solution containing at least one performance enhancing additive, (ii) water, and (iii) a solvent such as ethylene glycol monobutyl ether and diethylene glycol is applied to the article. The apparatus is made up of (a) a spray enclosure sized to contain the article(s) to be treated; (b) dispensing means, such as nozzles, which are configured to dispense sequentially, hot solution (i), hot solution (ii) and hot water (iii) directly onto the article surface(s); (c) means for securing and transporting the article to be treated into and out of the spray enclosure (such as a trolley system); and at least three closed vessels capable of delivering enough hot saturated coloring and/or performance enhancing solution, hot dye-free rinse solution and deionized water, respectively, with sufficient pressure to form small droplets from the spray nozzles, to thoroughly cover and rinse articles contained in the enclosure.
