Abstract: A flame resistant wood veneer assembly in the four embodiments, includes a decorative wood veneer layer, and a combination of aluminum foil layer(s)/backing(s) and a non-decorative wood veneer layer(s)/backing(s), the aluminum foil layer is bonded to the decorative wood veneer layer and between the non-decorative wood veneer layer(s)/backing(s) with phenolic adhesive at high pressure and high temperature wherein the high pressure is at least 150 pounds per square inch and the high temperature is at least 275 degrees Fahrenheit and where such high pressure and temperature is applied for at least four minutes. The resulting assembly is preferably wide belt sanded to produce a smooth, flat veneer product.

Abstract: A fire resistant wood veneer assembly includes at least a decorative veneer layer and at least one aluminum foil layer. The aluminum foil layer is bonded to the decorative wood veneer with phenolic adhesive at high pressure and high temperature to produce a fire resistant veneer assembly. A additional non-decorative veneer layer may also be bonded to the aluminum foil layer and the resulting veneer assembly may be precision belt sanded on the non-decorative side to produce a flat decorative fire resistant veneer assembly.

Abstract: A hand-held, small, lightweight instrument is disclosed that contains a light source capable of producing radiant energy in the spectral range between approximately 370 and approximately 410 nm, and an optical direction system for irradiating a target tissue by producing an illuminated spot thereon. A collection system is provided for receiving and directing fluorescent emissions in the frequency range between 450 and 700 nm returned from the target area to a detector. A processing system is used to determine the state of the tissue by using at least two and up to five spectral bands, preferably each being larger than 45 nm. Pairs of ratios of fluorescent intensities are compared to identify cancerous cells. An alphanumeric, false-color image and/or audio signal is immediately provided to inform a user of the state of the tissue.
