Abstract: A class of structural oxidation resistant ceramic base materials are described. The materials consist of an oxide matrix, which is resistant to the transport of oxygen by diffusion, and this matrix contains metallic fibers of a material which develops a stable protective oxide layer. The overall material composition is approximately eutectic so that the fiber-matrix combination can be formed by solidification directly from the melt. Directional solidification may be employed to produce a structure with oriented fibers.

Abstract: Diaper tab stock comprises a unitary substrate extending, transversely to machine direction, along first and second endward length portions separated by a third intermediate length portion, with adhesive on its topside at the first endward length portion, on its bottom side at the second endward length portion, and on neither side at the third intermediate length portion which separates the other two. A release coating on the bottom side of the first length portion extends partly onto the intermediate third length portion but stops short of the second length portion.In a preferred method of manufacture and use, a release coating on the top side of the second length portion serves as a releasing support both for the adhesive which ends up on the bottom side of the second length portion and then for the adhesive on the first length portion when the first length portion is folded onto the second length portion.
Abstract: An improved composition is disclosed which consists of organic resins and silanes. The compositions are useful finishing resins for textiles, fibers and paper. An example of the improved composition is a copolymer resin containing at least one type of acrylic acid ester combined with at least one type of unsaturated aliphatic acid and, a silane containing epoxy groups.
Abstract: An embossed film-to-foam laminate is provided having minute perforations through the film selectively distributed essentially along the sidewalls and valleys of the embossed pattern. The integrity of the laminated film material is retained on the crowns of the embossed patterned surface, since the perforations in the film material are mainly distributed on the sidewalls and valleys of the embossed pattern. The laminated product has a water-resistant and abrasion-resistant upper surface imparted by the film material on the crowns while the small perforations in the sidewalls and valleys permit sound to pass through the film and be exposed to the acoustical matrix of the open cell foam component of the laminate while impeding the penetration of liquids (e.g. water) through the film into the foam under the action of gravity. The film and/or the foam material are heated to supply adhesive material by melting or softening which serves to bond the film material to the foam.
Abstract: A master adapted to be imaged in the manner of an electronic stencil for use in producing multiple copies containing latent images in which the master comprises a base sheet having multiple coatings including a first coating containing an alcohol and/or water soluble colorless colorforming component and a highly electrically conductive coating overlying the first coat and which, in addition, contains a less highly electrically conductive coating overlying the highly electrically conductive coating and a masking coat as the top coat.

Abstract: A soft, absorbent fibrous web is formed from an aqueous slurry and includes randomly arranged and contacting wood pulp fibers produced by the sulfate process which constitute the predominate fiber component, by weight, of the web. A portion of the web thickness is substantially free of debonders and wet strength additives, and the fibers in that portion of the web are held together almost exclusively by papermaking bonds. A plurality of partially fractured areas are provided in spaced-apart regions which are substantially uniformly distributed throughout the web. An adhesive bonding material extends only partially through the web thickness to form adhesively bonded regions having a greater strength than underlying regions which are bonded together almost exclusively by the papermaking bonds. The web of this invention has a basis weight in the range of from about 25 to about 100 lbs/2,880 feet.sup.2, a density of from about 0.08 grams/cc to less than about 0.16 grams/cc.
Abstract: Nylon 66 yarn having particular stress-strain properties, typically also having a soft, luxuriant hand in fabric form. As compared to conventional nylon 66 with comparable boiling water shrinkage, the novel yarn exhibits a higher modulus at break, a lower modulus at 10% elongation, a positive stress index, and excellent denier uniformity. The process involves subjecting the yarn, within 0.016 to 0.11 seconds after solidification of the filaments, to a tension of 0.2 and 1.5 grams per final denier and heating the yarn to a temperature between 50.degree. and 250.degree. C. long enough to reduce yarn retraction below 1%.
