    摘要： In a method and apparatus for producing lightweight constructional plates by casting a mixture of filling materials and a binder into a mold, a cement and water are continuously centrifuged to form a liquid cement binder, and the binder and filling materials are continuously fed to a slowly rotating drum mixer to form the mixture. The mixture is continuously supplied to a mold while the mold is moved at a speed coordinated with a rate of mixture supply thereto to fill the mold progressively to a uniform height, while progressively subjecting only the mixture in the mold to vibration and to leveling to a uniform height. The mixture is supplied to the mold at a rate so coordinated with the rate of mold movement that the hardening reaction of the liquid cement binder just begins when the mixture is subjected to such vibration. As each mold is filled and the mixture therein vibrated, the mold is transported to a curing area and, when the cast mixture has hardened and cured, it is removed from the mold and the mold is returned for refilling. A glass fiber mat, soaked in a liquid cement, is applied to at least the under surface of the cast mixture while the mixture is being cast and before the liquid cement coating of the glass fiber mat has completely solidified. The liquid cement applied to each glass fiber mat preferably has an addition of 20 to 30 percent of natural or synthetic rubber. Each plate may have imbedded therein one or more reinforcing grids, and these reinforcing grids, as well as the glass fiber mat or mats are supplied to the mixture in the mold in a continuous manner while each mold is being filled and its mixture vibrated.

    摘要： A nanoparticle comprises a nano-active material and a nano-support. In some embodiments, the nano-active material is platinum and the nano-support is alumina. Pinning and affixing the nano-active material to the nano-support is achieved by using a high temperature condensation technology. In some embodiments, the high temperature condensation technology is plasma. Typically, a quantity of platinum and a quantity of alumina are loaded into a plasma gun. When the nano-active material bonds with the nano-support, an interface between the nano-active material and the nano-support forms. The interface is a platinum alumina metallic compound, which dramatically changes an ability for the nano-active material to move around on the surface of the nano-support, providing a better bond than that of a wet catalyst. Alternatively, a quantity of carbon is also loaded into the plasma gun. When the nano-active material bonds with the nano-support, the interface formed comprises a platinum copper intermetallic compound, which provides an even stronger bond.
