The present invention provides an aerospace or aircraft transparency which, generally, comprises a cast acrylic having a conductive acrylic incorporating a conductive ionic polymer is cast thereatop and cured. In a second embodiment hereof, a stretchable acrylic formulation having a conductive polymer admixed therewith along with a minor amount of a cross-linking agent cast atop a ply of unfilled stretchable acrylic. The stack is simultaneously cured and then stretched.

This invention is directed to a process for applying a symbol to a molded device which symbol on the molded device is visible as an indentation in the surface of the device. The process involves the step of applying the symbol as an elevation to the mold before using the mold for making the molded device. The process of the invention is characterized in that the elevation on the mold is produced by applying a material to the mold surface which material is liquid when being applied and which material is applied at a temperature higher than the temperature which is at or preferably below the melting point of the material, and which material solidifies at the temperature of the mold. The material applied to the mold and solidified on the mold surface as an elevation needs to remain solid during the process of using the mold for making the molded device. During the molding process the elevation of the symbol on the mold is transferred as an indentation of the symbol to the surface of the molded device. After the molding process is complete and the molded device has been separated from the mold the elevation on the mold surface can be removed and the mold can be re-used without an elevation or with another elevation being applied to make another molded device.

A molded flexible polyurethane foam having a hardness gradient going from soft to hard from the top to the bottom of the foam. The hardness gradient in the foam is a result of a foam elasticity gradient which arises from a polymer elasticity gradient and/or density gradient. A method for producing a flexible foam having a hardness gradient and a reactive mixture suitable for making said flexible foam is disclosed. Furthermore, the use of the flexible foams having a hardness gradient in matrasses, cushions for seating (more in particular for use in automotive seating), furniture, automotive under-carpets and dash insulators is disclosed.

A composite material system having an aggregate bound by an elastomer encapsulant. The composite material (CM) is designed to defeat impinging projectiles by converting the kinetic energy (KE) in the projectile to damage in the aggregate and the elastomer and increasing the thermal energy in the CM and the projectile via frictional heating. In one embodiment, the CM comprises certain kinds of rocks encapsulated (or bound) in a hyper-elastic polymer, such as polyurethane (“PU”). The CM may be shaped into convenient shapes from modular assembly to create a ballistic resistant surface.

The invention relates to the film products and methods of their preparation that demonstrate a non-self-aggregating uniform heterogeneity. Desirably, the films disintegrate in water and may be formed by a controlled drying process, or other process that maintains the required uniformity of the film. The films contain a polymer component, which includes polyethylene oxide optionally blended with hydrophilic cellulosic polymers. Desirably, the films also contain a pharmaceutical and/or cosmetic active agent with no more than a 10% variance of the active agent pharmaceutical and/or cosmetic active agent per unit area of the film.

Embodiments of the microfluidic device may include of an array of microfluidic cell capture chambers, each functionalized with a different antibody to recognize a target antigen, and a network of code-multiplexed Coulter counters placed at strategic nodes across the device to quantify the fraction of cell population captured in each microfluidic chamber. For example, an apparatus may comprise a fluid inlet port divided into a plurality of separate microfluidic paths, each separate microfluidic path configured to transport a plurality of cells, the plurality of separate microfluidic paths, each comprising a plurality of microfluidic cell capture chambers, an outlet port to discharge a merged output of cells from the plurality of microfluidic cell capture chambers, and a plurality of sensors to detect cells passing into or out of a microfluidic cell capture chamber.

The invention relates to a reversible microfluidic chip comprising at least one lower part and at least one upper part configured to come into contact with said lower part and to close said chip, said lower part and/or said upper part comprising a microfluidic structure, and said upper part comprising at least one layer of a flexible epoxide polymer material and at least one layer of a rigid epoxide polymer material, at least one part of the flexible layer being directly in physical contact with the lower part of the chip when said chip is in the closed configuration, to the method for the fabrication thereof, to the use of said upper part in a reversible microfluidic chip, to said upper part for producing said chip, and to the uses of said chip in various applications.

Collapsible vessels comprising a rubbery material can be folded or scrunched into a small volume, and then spring into a shape suitable for holding water or food such as for a pet.
