Abstract: A gyricon or twisting-particle display based on nonspheroidal (e.g., substantially cylindrical) optically anisotropic particles disposed in a substrate. The particles can be either bichromal or polychromal cylinders, preferably aligned parallel to one another and packed close together in a monolayer. A rotatable disposition of each particle is achievable while the particle is thus disposed in the substrate; for example, the particles can already be rotatable in the substrate, or can be rendered rotatable in the substrate by a nondestructive operation performed on the substrate. In particular, the substrate can be made up of an elastomer that is expanded by application of a fluid thereto so as to render the particles rotatable therein. A particle, when in its rotatable disposition, is not attached to the substrate. The close-packed monolayer configuration of particles provides excellent brightness characteristics and relative ease of manufacture as compared with certain other high-brightness gyricon displays.

Abstract: The present invention provides a water repellant, water resistant, stain resistant fabric that feels like fabric rather than plastic.

Abstract: A durable belt device includes an outer layer made out of a rubber based material and an inner layer that includes at least one reinforcing ply of tear-resistant scrim fabric located between opposed surfaces thereof and a multiplicity of needle fibers that run substantially transversely and perpendicularly through the reinforcing ply and protrude out from at least one surface of the inner layer. A bonding agent forms an intermediate layer that secures the outer layer to the one surface of the inner layer such that the fibers at least partially extend therein.

Abstract: The fiber compound material contains at least one fiber component and at least two matrix components of different material classes which have different thermo-mechanical properties. In a manufacture of the compound material two matrix components can be liquefied and fiber filaments of the fiber component can be wetted by the liquefied matrix components. In this in the liquefied state the one matrix component is not soluble in the other. In a consolidation of the compound material one of the previously liquefied matrix components can be hardened out irreversibly to a duroplastic whereas the other of the previously liquefied matrix components remains meltable.

Abstract: A method and apparatus for manufacturing fiber-reinforced, composite materials relies on one or more processes improving over conventional forming, filling, and processing techniques. A homogeneous resin-stitching process provides for resin stitching for using only 5-20 percent of the rovings in a preform as wetted rovings, cured to maintain a stitching together of the structure. A resin-packet transfer process provides infusion of resins from directly beside a wall of a preform, rather than passing resins throughout the longitudinal length of fibers in a perform. A cyclic vacuum bagging process alternately applied over pressure and outside vacuum to a vacuum bag process, thus relieving pressure, and later, optionally, applying pressure to improve structural strength. Relieving pressure tends to improve (reduce) porosity.

Abstract: Defects of printed patterns occurring during screen printing are repaired with high efficiency by employing a defect repair sheet in which a material layer for repair is formed on a transparent sheet and an adhesive layer is formed on the transparent sheet in order to cover the material layer for repair. The defect repair sheet is pressed on a defective portion of a predetermined pattern formed on a base by printing, thereby transferring the material layer for repair to the defective portion. The transferred portion is then subjected to, for example, a laser irradiation, so that the adhesive layer transferred together with the material layer for repair is vaporized and the material layer for repair is fired or heated and hence evaporated.

Abstract: In a friction material including a fibrous reinforcement, a friction modifier and a binder, no whisker-like potassium titanate fiber is contained, but powdery or flaky potassium titanate with an aspect ratio of not higher than 3 is mixed as a friction component. The diameter of the powdery or flaky potassium titanate is preferably in a range of from 0.05 &mgr;m to 150 &mgr;m. In addition, the powdery or flaky potassium titanate is preferably subjected to surface treatment with a silane coupling agent, phenolic resin, or the like. Further, fibrous potassium titanate may be mixed at a volume ratio of not higher than 30% with respect to the powdery or flaky potassium titanate. The fibrous potassium titanate is a by-product when the powdery or flaky potassium titanate is produced and which has a length of not longer than 5 &mgr;m or a diameter of not smaller than 3 &mgr;m.

Abstract: A method of fabricating a ceramic structure as well as a pre-ceramic preimpregnated composite material incorporating a continuous woven fiber and a discontinuous fiber pre-ceramic matrix for subsequent curing and component construction. The method includes preparation of a mixture of discontinuous fibers, fillers, and a pre-ceramic precursor resin where the precursor resin is present in a quantity sufficient to substantially saturate subsequently adjacent woven fiber lengths, and thereafter introducing the mixture to a situs between an upper length of woven fiber and a lower length of woven fiber in alignment with each other while effectuating linear movement of these woven fiber lengths and moving the lengths toward each other for compression and retention in a sandwich configuration to thereby fabricate a pre-ceramic preimpregnated composite material. The material is cut to size in accord with the configuration of a part to be manufactured, formed into a green-state structure, and cured.

Abstract: Non-flammable, fibrous-siloxane cured composites derived from the polymerization of dialkoxysilanes, trialkoxysilanes and tetraalkoxysilanes, in an aqueous medium, to obtain viscous polysiloxane resins. These siloxane resins are used to impregnate or coat various fibrous materials such as carbon fibers or glass cloth which are subsequently subjected to heat and pressure to form cured, non-flammable siloxane-impregnated composites e.g. panels having a density of about 1 to 3 g/cc. and a limited oxygen index above 30. These non-flammable, fibrous-siloxane composites are particularly useful in the manufacture of fire-proof materials for various transportation vehicles and for building materials e.g. panels as a fire barrier.
