Abstract: A laminated printing blanket having compressible and resilient properties and a method for its production are provided. The compressible characteristics are provided by disposing an intermediate layer having substantially uniformly distributed voids of substantially uniform size between the base ply and the working surface of the printing blanket. The voids of the compressible intermediate layer are formed by introducing high melting point microspheres formed from thermoplastic resins into an elastomeric matrix, coating said microsphere containing elastomeric matrix upon an upper surface of the base ply and then vulcanizing the coated base ply at a temperature of between about 80-150.degree. C. for between about one and six hours to form the compressible layer having substantially uniform compression characteristics. Once all of the layers of the blanket are stacked, a final vulcanization treatment at between about 132-160.degree. C.

Abstract: A breathable membrane and a method of constructing a fabric having the membrane, wherein the membrane is resistive to transport of liquid water, has a layer of breathable material and is stabilized dimensionally against distension by a force field, such as forces which may be applied to the membrane or resulting from a hydrostatic pressure, by a reinforcing matrix of nonwoven filaments extending in plural directions along the layer of breathable material to inhibit the distension. In the matrix, the filaments are arranged in a first plurality of the filaments which intersect a second plurality of the filaments to form cells. A minimum diameter of an individual one of the cells is greater by at least approximately an order of magnitude than a diameter of one of the filaments to provide open areas of the layer of breathable material which are free from obstruction by the filaments.

Abstract: A thermal insulation is produced by forming aerogels interstitially within a fiber matrix. The resulting composite structures have substantially no fiber--fiber contacts.

Abstract: Methods and systems for making an absorbent pad for use in an absorbent article utilize a forming device for forming material into an absorbent core, a supply device for supplying a containment layer against the first surface of the absorbent core and spray apparatus for spraying fibers of molten resin onto the second surface of the absorbent core. The fibers form a stabilization layer on the absorbent core that increases the integrity of the absorbent core. The spray apparatus includes a nozzle having a resin aperture for exhausting resin therefrom and multiple gas apertures for exhausting gas therefrom to provide a random pattern to the fibers of molten resin as the fibers are sprayed onto the second surface. Resin can also be sprayed onto first and second portions of the containment layer extending outwardly from edges of the absorbent core so the containment layer and the stabilization layer encompass the absorbent core.

Abstract: First and second molten resins are continuously injected toward the respective circumferential surfaces of a die wheel and an associated roller in rotation in opposite directions. The die wheel has in its circumferential surface a multiplicity of engaging-element-forming cavities, and the associated roller is disposed in parallel confronting relationship with the die wheel with a gap equal to the thickness of a substrate sheet of a molded surface fastener member. During that time, a porous core sheet is introduced toward a meeting point of the first and second molten resins and is sandwiched between a first substrate sheet part, which is molded on the circumferential surface of the die wheel, and a second substrate sheet part, which is molded on the circumferential surface of the associated roller, to form a unitary laminate substrate sheet. The resulting molded surface fastener member is free from expansion and local thin portions in either substrate sheet part and is therefore prevented from being torn.

Abstract: A method of coating the surface of a substrate, such as a film or a fibrous web, which is composed of a hydrophobic polymer. The method involves providing a solution of a first polyelectrolyte having ionizable groups and a solution of a second polyelectrolyte having ionizable groups. The two solutions then are mixed under conditions adapted to result in the formation of a nonstoichiometric polyelectrolyte complex. Finally, the surface of the hydrophobic polymer substrate is contacted with a solution of the complex under conditions sufficient to result in the coating of the surface of the substrate with the complex. The ionizable groups of the second polyelectrolyte have a latent charge opposite the latent charge of the ionizable groups of the first polyelectrolyte.

Abstract: A membrane coated with or incorporating a number of different types of microcapsules is disclosed. A first and second type of microcapsule each contain one component of a chemical reaction that produces a chemical agent that is capable of dissolving the shells of all microcapsules, while a third type of microcapsule has a dye or other indicator encapsulated by a chemically dissolvable shell. A structural violation of the membrane also violates the capsules, causing not only the release of an indicator or pharmacologically active substance from the capsules but also the initiation of chemical chain reaction that broadens the scope of the reaction that broadens the scope of the indication beyond the site of the initial breach in the membrane.

Abstract: A high temperature and highly corrosive resistant structure and method of fabricating the structure. In one embodiment of the present invention, vacuum plasma spray or other materials deposition techniques are used to fabricate the structure on a removable support member in the form of a gradient or composite structure that sequentially consists of a 100% ceramic interior layer, a first transition layer of ceramic/refractory metal, a layer of 100% refractory metal, a second transition layer of ceramic/refractory metal, and an outer layer of 100% ceramic material.

In another embodiment of the invention the structure is fabricated on a removable support member by depositing an outer layer of ceramic material on a refractory metal. No transition layers of ceramic material/refractory metals are used.
