A preparation of the semi-rigid polypropylene floorboard is also provided, in which the polypropylene wear-resistant layer, the polypropylene decorative layer, the adhesive layer, the polypropylene substrate layer and the enhancement layer are subjected to hot-pressing lamination, tempering, punching and trimming to obtain the desired product.

A transaction card includes at least one metal layer having one or more apertures therein. A light guide is disposed beneath the metal layer. The light guide has a light output and a light input. The light output is positioned to transmit light through at least the one or more apertures of the metal layer. At least one LED is positioned to transmit light into the light guide light input.

This invention relates to the production of cured polymeric skin materials. In particular, the invention relates to methods and substrates for the production of skin materials, for example, for use in building, furniture, and as architectural components for example in roofing materials such as roofing tiles, or for brick wall effect materials.

The present invention relates to a multi-layer wood composite block, a multi-layer wood veneer and methods for producing the same. Furthermore, the invention relates to the use of the multi-layer wood veneer as a decorative and/or trim element, in particular in a vehicle interior, and articles comprising the multi-layer wood veneer.

A layered device having two base films, a conductive pattern attached to the first base film facing the second base film and a bonding layer binding the first base film and the second base film together. The bonding layer includes an opening, and the conductive pattern having an exposed portion aligned with the opening in the bonding layer. Further disclosed is a spacer attached to the first base film and the exposed portion of the conductive pattern, wherein the spacer fills at least part of the space created by the opening in the bonding layer. Also disclosed is a method of producing a layered device.

This patent is a new method of constructing composite stiffened building materials. Conventional door construction materials are made of solid wood, MDF, or LVL. Solid wood tends to move over time and is very heavy. MDF and LVL core doors tend to be extremely heavy and both have a tendency to delaminate or move over time, especially when exposed to moisture. This new method of building stile and rail doors will create lasting stile and rail doors of any size last without warping and remaining high strength, lightweight, and rigid. The stiles, or horizontal members, and rails, or vertical members, can be made of honeycomb core, laminated alternating wood products and stiffening materials like the Composite Stiffener, U.S. Patent No. 63/313,649.

The composite stiffener comprises of multiple layers (at least 2) of aluminum, formica, plastic, sheet metals, fiberglass, or other strengthening materials: plywood, vencer, multiple layers of veneer, MDF, or other wood products for adequate bonding surface; and honeycomb core, paper core, hollow core, or other filler materials. The materials listed above can alternate and be adhered with an adhesive. Once the adhesive is fully cured, the layers of materials can be cut length-wise or width-wise perpendicular to the width edge of the sandwiched materials. Thickness of the section being cut is determined by the thickness of the core used in the panel the composite stiffener is intended for. The section that was previously cut off, is the composite stiffener, to be placed with the end grain to each surface of the panel requiring the stiffener. With the end grain of the stiffener facing the inner surface of the panel, or the stiffener layers are perpendicular to the surface of the panel, ensures the panel containing the stiffener will remain straight and not warp, bend, twist, or otherwise fail.

The composite stiffener material can have lumber adhered to at least two sides with any adhesive. Skin material can be adhered to the top and bottom faces of the composite stiffener core material. Skin material can be flat building materials such as plywood, vencer, multiple layer vencer, MDF, HPL, formica, plastics, aluminum, metals, fiberglass, or other flat building materials. This creates the composite stiffened building materials like stiles and rails material. They can be profiled to fit together with the desired amount of panels.

The application relates to a water transfer compound, preferably for use for the humidification of process gases for fuel cells, comprising:a water-permeable and essentially gas-impermeable water transfer layer as well asat least one thermoplastic protection layer which is water- and gas-permeable at least in sections, wherethe water transfer layer and the thermoplastic protection layer overlap each other at least in sections and comprise a first and a second overlapping area, wherethe water transfer layer in the first overlapping area is accessible for humid gases through the thermoplastic protection layer and the water transfer compound is thermocompressed in the second overlapping area so that the water transfer layer in the second overlapping area is not accessible for humid gases through the compressed thermoplastic protection layer.

Provided are: a sheet for pets which contains carbon and has a superior appearance, and a method of manufacturing the sheet for pets. A sheet for pets is provided with a liquid-permeable front surface sheet, a liquid-impermeable back surface sheet, an absorbent layer that contains carbon and organic acid and is positioned between the front surface sheet and the back surface sheet, and a front surface-side liquid-permeable sheet that is black and is positioned on the front surface sheet-side of the absorbent layer. The front surface-side liquid-permeable sheet is preferably formed from pulp fibers that have been dyed black.
