Abstract: In a system and method for producing a mosaic image, a printable substrate has a front side that defines a first area and a second area. Both the first and second areas are printable. A back side of the printable substrate features a pressure-sensitive adhesive and a backing. The first area corresponds to a region of a physical matrix of regions. A source image may be printed on the first area to define a tile and an address of the tile on the matrix of regions may be printed on the second area. The tile may be peeled from the backing separately from the second area to reveal the pressure sensitive adhesive. Users may adhere a plurality of tiles to the matrix of regions at the addresses on the second areas to define the mosaic image.

Abstract: A liquid foam system and process for treating an aqueous medium volume includes foam breaking equipment for treating foam floating on a liquid medium. The foam breaking equipment includes a foam conveyer, a rotatable driven screw for sucking foam present in the foam conveyor and for causing at least a partial defoaming of the foam and for expelling foam out of the foam conveyor, and an exhaust gas tube for removing gas within the foam conveyor released from the foam during defoaming. The foam breaking equipment may be used in conjunction with a first tank having a liquid medium and the process includes conveying foam downwardly into the foam conveyor and at least partially defoaming the conveyed foam.
