Abstract: A coloring system and a manufacturing process for coloring artificial covering stones are provided. A board layout represents a board of artificial covering stones. Several natural stone color patterns are provided, each being different from one another. The natural stone color patterns are associated with selected artificial stones of the board layout. Graphic parameters represent the natural stone color and are converted into coloring instructions. A conveyor conveys the board of artificial covering stones, and a positioning system determines respective positions of the artificial covering stones of the board, relative to a reference position. An in-line coloring device colors the artificial covering stones with the natural stone patterns, according to the coloring instructions and to the positions of the artificial stones. The selected artificial stones colored by the system are thus different from other stones of the board, and have a distinct, natural random-look.

Abstract: An automatic disc handling system and method for retrieving and positioning information carrying discs between a storage position to a position of use is described. A displaceable robot having a pair of robotic arms is controlled by a computer connected to a robot controller and instructed to move to discrete positions, either in front of storage racks where a plurality of superposed sliding trays containing one or more discs are stored, or to a plurality of playback units disposed at a position of use to move selected ones of the disc to and from these positions as requested by a person accessing the discs from a remote station. The robot is provided with a tray engaging element to move the tray in and out of its storage position, and the robotic arms of the robot are each provided with a picker mechanism to engage and remove the discs from the trays or the playback units and transport them to effect a function as dictated by the computer and the robot controller.
