Abstract: A document laminate includes laminating sheets with adhesive on facing sides to laminate a document between the sheets, and shielding sheets covering the document and received within the laminating sheets. When the adhesive is heat activated, the shielding sheets are selected to be not degraded by the activating heat. A document can therefore be removed from the laminate by cutting along a line at one edge of the shielding sheets, and removing the document, which is not adhered to the shielding sheets or the laminating sheets.

Abstract: A molded wood composite article man-made from wood fibers or wood particles on at least an upper, molded surface of the article, and a method of manufacturing the article to include a relatively uniform density, detailed design contours and textured aesthetics on one or more molded depression-interior inclined surfaces, while preventing embrittlement, softness and blistering of the article along the depression-interior inclined surfaces. These attributes are achieved by molding one or more depressions into an initially planar layer of cellulosic material, wherein the molded depressions have one or more inclined walls that have upper surfaces, along essentially an entire inclined span, that include detailed design contours, including adjacent curved and planar portions, e.g., bead and cove.

Abstract: Disclosed is a process for producing a crimp-bonded fibrous cellulosic laminate. The process includes the steps of: 1) providing at least two superposed plies of a fibrous cellulosic material; 2) passing the superposed plies through a crimp roll arrangement including a rotating crimp element and a rotating anvil element; and 3) applying a pressure load against the rotating elements sufficient to crimp bond the fibrous cellulosic material plies into a laminate. The crimp element has protruding members configured in a discontinuous pattern aligned on an axis that is parallel to the cross-machine direction to provide a substantially continuous uniform area of localized surface contacts between the rotating crimp and anvil elements across the width of the plies. Also disclosed is an overall crimp-bonded fibrous cellulosic laminate and an apparatus for crimp-bonding multiple superposed plies of a fibrous cellulosic material.

The layer structure is formed by one layer of individual elements that are electrically connected to one another via quantum-mechanical tunnel contacts.

Abstract: A method of manufacturing a three-dimensional fabric of the type which may be used in absorbent garments, dressings or the like involves the use of an apertured collector element which has a predetermined three-dimensional shape. The method involves positioning material adjacent to one side of the apertured collector element and developing a pressure differential between the one side of the apertured collector element and a second, opposite side to force the fabric material against the apertured collector element. The material, which has conformed to the shape of the collector element, is then solidified into its intended three-dimensional shape.

Abstract: A process for the production of a laminated glass glazing having one or more wires within an intermediate thermoplastic layer and electrically connected to busbars, wherein the wires are heated by an adequate energy application locally limited to the connection points prior to the electrical connection to the busbars, to the extent that the surface layers adhering to the surface of the wires are eliminated. The application of a locally limited adequate energy supply takes place by use of laser rays, as a result of the fact that the focus of a beam of laser rays oriented perpendicular to the busbars is displaced in the longitudinal direction above and on the busbars. The wires are then welded to the busbars. The layers forming the laminated glass glazings are presently assembled in a conventional manner and joined to one another under heat and pressure.

Abstract: Disclosed is a fiber of an organic, inorganic or metallic material or a simple substance wherein ultrafines of an inorganic or metallic material or a simple substance having an average particle diameter of 0.005-1 .mu.m are uniformly dispersed and deposited on 8-90% of the surface in a single layer. The fiber is produced by exposing a fiber of an organic, inorganic or metallic material or a simple substance to a gaseous stream forming ultrafines of an inorganic or metallic material or a simple substance by a vapor phase process, thereby contacting said ultrafines in the gaseous stream with said fiber in a state wherein the ultrafines are still active. The treated fiber is useful as a reinforcing material for a fiber reinforced composite.

Abstract: An improved graphite composite shaft which can be used in fishing rod or golf clubs includes a base shaft made at least partially of graphite composite material provided in one or more layers or plies. Each shaft has a relatively slender tip that is normally prone to impact damage. An outer concentric reinforcement layer made of a composite material having thermoplastic fibers, such as Vectran, Spectra, or the like, is provided on the base shaft. The reinforcement layer extends only part of the way up the length of the base shaft from the tip thereof. The reinforcement layer makes the shaft more resistant to impacts occurring at the tip, thus increasing the durability of the shaft without decreasing the performance of the fishing rods or golf clubs that incorporate the shaft.
