Abstract:
An artificial flagstone for use in combination with other similar flagstones for covering a surface with a natural random look, the flagstone having a generally hexagonal body comprising a first, second, third, fourth, fifth and sixth consecutive vertices; a first pair of first and second sides extending radially from the first vertex; a second pair of third and fourth sides extending radially from the third vertex; a third pair of fifth and sixth sides extending radially from the fifth vertex; wherein the sides of at least one of the first, second and third pair of sides have at least one split deviation along their length and are respectively rotational images of each other, and the artificial flagstone has no rotational symmetry when rotated about a central axis.

Abstract:
The present invention provides an apparatus and a method for aging a stone, preferably an artificial stone. The aging device comprises a rotary support operatively connected to a rotary shaft, at least one abrasive tool mounted to the rotary support for roughing and/or polishing a surface of the artificial stone when the rotary support is brought into functional contact with said surface, and biasing means that biasingly connect the abrasive tool to the rotary support. The biasing means urge the abrasive tool away from the rotary support while allowing the same to move toward the rotary support when the rotary support is brought into functional contact with the surface of the artificial stone, thereby allowing the abrasive tool to follow a surface profile of the artificial stone while roughing and/or polishing its surface.
Abstract:
A concrete slab for forming blocks for a retaining wall comprises a prism having parallel top and bottom surfaces, and opposed parallel side walls, and end walls, the prism has an X axis in the longitudinal direction extending between the end walls, a Y axis in the width direction extending between the side walls, and a Z axis perpendicular to the X and Y axes extending between the top and bottom surfaces. A first dividing line extends parallel to the X axis from one end wall to the other end wall in order to define a separating plane bisecting the prism. At least a pair of dividing lines extend parallel to the Y axis of the prism from the first dividing line to each of the opposite side walls, wherein the second dividing lines are parallel to each other but offset therefrom, whereby upon separating the slab along the first and second dividing lines, at least four blocks in the form of rectilinear prisms having different dimensions in the X axis will be formed. A molded block for a retaining wall is also defined having tapered end walls that are tapered and ears project from these end walls, parallel to the X axis and adjacent the rear wall.
