Abstract: According to some embodiments, there is provided a method of producing a patterned artificial marble slab (2, 5, 11, 16). The method includes adhering one or more patterned substances (1) to a surface of the artificial marble slab, processing said artificial marble slab and removing said one or more patterned substances from the surface of the artificial marble slab, thereby obtaining an elevated or recessed pattern (3, 4, 6, 7, 9) on the surface of the artificial marble, wherein the elevated or recessed pattern has essentially the form of the patterned substances.

Abstract: A method and apparatus for engraving or etching the surface of a solid surface material such as stone, tile, or the like, utilizing a combination of a laser and a corrosive agent. A mask material configured to be applied to the top surface of the solid surface material. A laser is utilized remove mask material to form desired designs in the mask material. A corrosive agent is applied to the portions of the solid surface material exposed by the design of the mask to engrave the surface of the solid surface material.

Abstract: An impurities elimination apparatus including a base plate, a first nozzle for removing impurities on the base plate using air suction, a glass substrate disposed on the base plate, and a second nozzle for coating the glass substrate with an organic material.

Abstract: Powder composition and method for polishing stone. The present invention relates to a powder composition and to a method for polishing stone, in particular granite, said method making use of said powder composition.

Abstract: The invention relates to a method of manufacturing non-slip floor coverings made of mineral materials, such as, for example, natural stone, fine stoneware, artificial stone or ceramics. This method is carried out in a two-stage process, there being produced on the surface of the floor coverings or slabs, in a first process stage by means of pulsed laser bombardment, statistically distributed microcraters invisible to the human eye. The surface of the floor coverings or slabs obtained in this way is then, according to the invention, subjected to hydromechanical aftertreatment.

Abstract: A method for producing a porous diamond according to the present invention comprises steps of forming an anodized alumina layer, which functions as a mask, on a diamond substrate; and performing a plasma etching treatment to form pores on the diamond substrate, which pores have the same arrangement as those of the anodized alumina mask.

Abstract: A method for manufacturing a head suspension including separately manufacturing a load beam and a set of traces. The traces are formed from a sheet of conductive material and include an elongated conductor portion and a gimbal portion. Portions of the traces which are configured to be mounted to the load beam are coated with dielectric before being mounted to the load beam. The gimbal portion of the traces provides both mechanical and electrical connections to the conductor portion.

Abstract: A method for producing a wall, roadway, sidewalk or floor of cementitious material having the appearance of natural stone and mortar including a base with an outer surface with a plurality of irregular shaped protrusions disposed in a random pattern to simulate natural stones and a plurality of simulated grout lines formed therebetween, the method including the steps of preparing a cementitious material, pouring the cementitious material into a form, vibrating the cementitious material, allowing the cementitious material to cure forming the base with the outer surface, releasing the base with the plurality of irregular shaped protrusions disposed in the random pattern to simulate natural stones and the plurality of simulated grout lines formed therebetween from the form, coloring the outer surface and accenting the plurality of simulated grout lines.

Abstract: A method of decorating concrete including the steps of mixing water, aggregate and cement to provide mortar, pouring the mortar into a form and allowing it to cure and harden into a concrete block having an exterior surface, and applying sulfate to a selected portion of the block to color the surface of the block to a predetermined depth while the mortar is being cured.
