    摘要: The present invention relates to particles of an alkaline earth metal carbonate which are at least partially coated with at least one coating agent and which have a specific surface of more than 50 m2g−1 before coating. Preferably, the alkaline earth metal is calcium and the coating agent comprises a compound selected from the group consisting of organic sulfonic acids, alkylsulfates, fatty acids and the salts thereof.

    摘要: An apparatus for depositing a layer of thermoplastic material onto a surface bearing a recessed logo or other decorative design of a logo plaque mold, wherein the apparatus includes a cylindrical housing enclosing a rotatable shaft and spray gun extension. The rotatable shaft may be operatively connected to the housing for rotation along the centerline thereof, and the spray gun extension in secured to a side of the shaft such that the axis of the extension is parallel to the axis of the shaft so as to be rotated concentrically with the shaft when the latter is rotated. Thus, a suitable thermoplastic material is deposited on the recessed logo or design of an associated mold surface, providing for the retention of segments in the recesses for being bonded onto a subsequent base layer of thermoplastic material.
