Abstract: An expanded resilient product and methods for making the same are disclosed. The product is characterized as a geometric solid of resilient material that has a plurality of slits formed therein. Each slit is defined by a first surface having a protruding portion and second surface having a recess portion corresponding to the protruding portion of the first surface which together form an interlocking fit between the two. Forces are applied to the product sufficient to dislodge a protruding portion of the first surface from the complementary recess portion of the second surface, thereby forming a plurality of gaps. The product is then permitted to relax, whereupon the protruding portions compressively contact the complementary recess portions of the second surface. But because of the interlocking fit, the protruding portions are prevented from re-engaging the recess portions and thereby maintain the expanded nature of the product.

Abstract: The present invention provides an adhesive cloth tape for bundling the component wires of a wiring harness for use, for example, on an automobile. Conventional adhesive polyvinyl chloride tapes and adhesive acetate cloth tapes have problems that wiring harnesses bundled by these adhesive tapes generate fluttering and rustling noise while the automobile is running, and conventional adhesive cotton cloth tapes reduce the efficiency of bundling work because these tapes have high tear strength, though their noise preventing performance is excellent. The present invention provides an adhesive cloth tape solving the foregoing problems in the conventional adhesive cloth tapes, having a tensile strength of 8 kgf/19 mm or higher with respect to the direction of its length, and comprising: a woven base cloth of 0.

Abstract: Compositions, methods, and systems for manufacturing articles, particularly containers and packaging materials, having a highly inorganically filled matrix. Suitable inorganically filled mixtures are prepared by mixing together an organic polymer binder, water, one or more aggregate materials, fibers, and optional admixtures in the correct proportions in order to form an article which has the desired performance criteria. The inorganically filled mixtures are molded to fashion a portion of the mixture into a form stable shape for the desired article. Once the article has obtained form stability, the article is removed from the mold and allowed to harden to gain strength. The articles may have properties substantially similar to articles presently made from traditional materials like paper, paperboard, polystyrene, plastic, or metal. They have especial, utility in the mass production of containers, particularly food and beverage containers.

Abstract: Compositions, methods, and systems for manufacturing articles, particularly containers and packaging materials, having a starch-bound cellular matrix reinforced with substantially uniformly dispersed fibers. High strength articles that have adequate flexibility and toughness immediately or very shortly after being demolded without the need for subsequent conditioning are molded from compositions having a starch-based binder and fibers that are uniformly dispersed by means of a high yield stress fluid fraction within the starch-based composition.

The fibers preferably have an average length of at least about 2 mm and an aspect ratio of at least about 25:1.

The membranes comprise a porous composite of a thin layer of a multicomponent metallic oxide which has been deposited onto a porous support wherein the pores of the multicomponent metallic oxide layer are subsequently filled or plugged with a metallic-based species. The inorganic membranes are formed by depositing a porous multicomponent metallic oxide layer onto the porous support to form a porous composite having a network of pores capable of transporting gases. The network of pores are plugged or filled by organometallic vapor infiltration to form an inorganic membrane having essentially no through porosity.
