Patent number: 5211156Abstract: The method and apparatus treat a surface of natural rock or artificial stone-like material to give to this surface an attractive finish. A high temperature jet of plasma and a high speed jet of cooling fluid are projected onto the surface to be treated. The two jets are moved on the surface at a given speed with the jet of cooling fluid following the plasma jet. The speed of movement is selected so that the high temperature plasma jet heats only a thin superficial layer of rock or stone-like material. As the jet of cooling fluid follows the jet of plasma, it suddenly cools the thin superficial layer just heated by the plasma jet to cause a thermal shock which bursts particles of rock or stone-like material at the surface thereof, and blows these particles off the rock surface.Type: GrantFiled: November 1, 1991Date of Patent: May 18, 1993Assignee: Universite De SherbrookeInventors: Jerzy Jurewicz, Maher Boulos, Clermont Roy

Patent number: 4439657Abstract: Disclosed is an apparatus for high temperature treatment of rectilinear-generatrix surfaces of nonconductive products. The apparatus comprises an anode arranged opposite to a cathode to provide an arc gap therebetween for striking an arc discharge. The apparatus is further provided with a product feeding device to move the product a desired distance from the axis of the arc. The cathode is held securely in place, while the anode is positioned, integrally with the fixed cathode, to maintain a fixed position of the arc axis within the arc gap exceeding the length of the generatrix of the surface being treated. The feeding device is designed so as to provide the movement of the products in a plane extending normally to the axis of the arc when the generatrix of the surface being treated is parallel to the axis of the arc.Type: GrantFiled: July 30, 1979Date of Patent: March 27, 1984Assignee: Institut Fiziki Akademii Nauk Belorusskoi SSRInventors: Vladimir D.

Patent number: 4425059Abstract: The invention concerns the removal of a concrete covering applied to an underlying surface provided with an anti-corrosion coating, for example that of a hydrocarbon-conveying pipe.The coating is removed by making trenches in the concrete to divide it into removable elements, the trenches being made using a cylindrical milling cutter having a longitudinal diamond-faced toothing and provided with a central stud of tungsten carbide projecting axially from the end of the cutter. In use the stud contacts the surface to prevent the surface being damaged by the toothing on the cutter as the cutter is moved transversely across the surface. To initiate a concrete covering removal operation, a hole is first drilled through the covering perpendicular to the surface for receiving the stud. The cutter is then moved perpendicularly to the surface through the concrete with the stud projecting into the drilled hole and until the stud contacts the surface.Type: GrantFiled: November 10, 1981Date of Patent: January 10, 1984Assignee: Compagnie Francaise des PetrolesInventors: Claude Colas, Guy Herve, Jean-Louis M.
