Abstract: A device for displaying images having variable colors comprises a substrate; a light-transmissive coloring layer painted or laminated on the substrate, the coloring layer comprising colorants of different colors and having a rear side in contact with the substrate and a varnished front side; a display layer comprising a silvering material directly plated on the varnished front side of the coloring layer, the display layer comprising a display pattern forming a visible displayed image, the silvering material comprising a metal, a metalloid, or an oxide thereof to form a one-way-mirror; an illuminator configured and positioned to illuminate the coloring layer from the rear side of the coloring layer. When the coloring layer is unilluminated by the illuminator, the unilluminated coloring layer is hidden behind the one-way-mirror. When the coloring layer is illuminated by the illuminator, the illuminated coloring layer visibly colorizes the displayed image through the one-way-mirror.

Abstract: An article comprising natural stone and method for forming the article are provided. A counter-relief is formed at a back of the natural stone. A light-transmitting reinforcing material is bonded to the back of the natural stone at the counter-relief to reinforce the natural stone at the counter-relief. A front of the natural stone is carved to form a relief at the front. The relief is positioned opposite to the counter-relief. The thickness of the natural stone between the relief and the counter-relief is reduced by the carving to allow light to transmit through the natural stone from the back to the front to illuminate the relief.

Abstract: A near-zero-release treatment system and method for high concentrated organic wastewater is in the chemical engineering and environment protection field, whose core technology is SCWO. The wastewater and sludge are grinded by the homogeneous pump, pressurized by high-pressure plunger pump, transported to successive pipeline for preheating and mixing with the oxygen and undergoes SCWO reaction in the reactor. After pressure release in the pressure relief device, the reacted fluid passes through the self-cleaning filter and gas liquid separator for insoluble solid and gas separation; then enters the MVR for crystallization of the soluble salts to realize near-zero-release of the feeding. The regular water treatment technology (coagulation sedimentation, membrane biotechnology, membrane technology, etc.) is adopted to complement SCWO, which lowers the operating parameters of the reactor and cuts the operating cost by treating the remaining COD with regular water treatment technology.
