    摘要： The invention relates to a mold for the production of dishes from powdered ceramic materials wherein two coaxial cylindrical dies are displaceable to generate with their end facing walls a cavity to be filled with the powdered ceramic materials, said cavity being peripherally completed by a displaceable die-box provided with a vertical conduit through which the ceramic material is fed into said cavity. An auxiliary die-box is provided sideways on said die-box, displaceable at least along one of said cylindrical dies, the lateral facing walls of said die-box and of said auxiliary die-box (16) being provided with annular grooves that in the closed condition of said lateral walls generate an annular cavity that may be registered in correspondence with said first-mentioned cavity of the mold, radially prolonging the latter and forming the peripheral border of the dish to be produced.

    摘要： A method and apparatus is provided for the manufacture of products of concrete or like construction, in which a mixture of calcareous cementitious binder substance, such as cement, an aggregate, a vinyl acetate-dibutyl maleate copolymer, and an amount of water sufficient to make a relatively dry mix is compressed into the desired configuration in a mold, and with the mixture being exposed to carbon dioxide gas in the mold, prior to the compression taking place, such that the carbon dioxide gas reacts with the ingredients to provide a hardened product in an accelerated state of cure having excellent physical properties.
