Abstract: A sand screen filter for an oil or gas well includes a support frame and a cylindrical woven wire mesh attached to the support frame. The woven wire mesh has a randomly varying pore size and or shape which creates fluid flow passages of varying sizes for the produced fluid. The sand screen filter may include an apertured protective shroud and may be attached to a perforated tubular. The woven wire mesh element may be used in any filter that includes a woven wire mesh element.

Abstract: A screening system includes a first vibration generator, an excitation frame which is connected to the first vibration generator, and an excitation support screen which is connected to the excitation frame and includes first screen openings. A change screen held in a change frame has second screen openings of a size which is smaller than a size of the first screen openings. The change screen is arranged detachably from the excitation support screen and placed atop the excitation support screen, when assembled.

Abstract: A filter screen is formed by a first sheet metal frame having one or more cutout sections or a plurality of perforations. A first layer of screening is placed on top of the frame but does not extend to the edges of the frame. An optional second layer of screening may be placed over the top of the first layer such that it extends beyond the perimeter of the first layer but not to the perimeter of the frame. The assembly is then fusion bonded together and rolled into a tubular configuration. Abutting edges of the frame are welded together to form a rigid filter screen.

Abstract: There is described a novel woven-fabric packing 1, in which a plurality of woven-fabric layers 2 of metal or plastic filaments 3 are disposed parallel to one another. The woven-fabric layers 2 have protuberances 4, at least one protuberance 4 having an opening 5, which lies in an opening plane 6, which is oriented at an angle of 40 to 140 degrees relative to the woven-fabric layer 2. The openings 5 of woven-fabric layers 2 are all oriented in one opening direction X.

Abstract: A fabric packing has a plurality of layers made of a filament of metal or plastic and includes bulges for maintaining the fabric layers at a distance. The bulges have first protuberances of generally trough-shaped configuration and second protuberances formed on the first protuberances, thereby defining respective apexes. The second protuberances are sized smaller than the first protuberances, wherein neighboring fabric layers are supported on one another via the second protuberances.

Abstract: An integral structure including woven wire cloth or non-woven metal filter medium for use as a drainage layer or filter layer in a well screen assembly is provided. A plurality of elongated members are welded on the woven metal cloth or non-woven metal filter medium to provide reduced resistance to flow parallel to a layer of the woven cloth. Segments of the woven or non-woven metal materials having elongated members joined thereto may be rolled into a cylinder to form a part of a well screen assembly.

Abstract: An assembly and method is provided for a decorative panel which may be utilized as a screen, wall, or other structural surface comprises a wire mesh woven with flat, substantially flat, or planar surfaced wires mounted within transparent or translucent sheets of glass, polycarbonate, plastic, and/or other glass-like material. The wires comprise twisted portions within the weave thereof whereby the twisting flat, substantially flat or planar surfaces thereby produce a visual effect. During construction of the panel, one or more sheets of binding material are positioned between the transparent or translucent sheet along with the mesh. The assembly is heated and compressed to thereby form a panel with all components bound together.

Abstract: A machine for continuously making spirally wrapped tubular filter material screens utilizes a mandrel around which one or more strips of filter material are wrapped. The resulting spirally wrapped tubular filter material screen may or may not comprise multiple layers of filter material. In one embodiment, the strips of filter material are continuously resistance welded along or about the helical seams of the filter material strips utilizing an outer welding wheel and an inner welding wheel.

Abstract: A continuously or intermittently bonded spirally wrapped tubular filter material screen comprises one or more strips of filter material. The spirally wrapped tubular filter material screen may or may not comprise multiple layers of filter material. In one embodiment, strips of wire mesh are resistance welded to comprise one or more helical resistance welds. The spirally wrapped tubular screen can be cut to any desired length.

Abstract: An assembly and method is provided for a screen that may be utilized for filtering purposes including filtering drilling fluid in a vibrating shaker. In a preferred embodiment, at least one screen is formed of a plurality of planar wires that are woven together with a plurality of wires, which may or may not also be planar to thereby reduce the friction forces produced by the so-constructed screen. The screen formed with planar wires may be used by itself or in conjunction with other screens to produce a screen assembly that is resistant to vibration damage. The screen formed with planar wires may also be utilized to provide improved filtration performance by itself or in combination with other screens by offering a more precise opening at the initial point of contact therefore improving the de-binding function of the screen.

Abstract: An assembly and method is provided for a decorative screen, wall, or other surface to provide a desired amount of light passing through, reflected by, and/or diffused by the decorative screen. In one preferred embodiment, at least one screen is formed of a plurality of wires that are woven together. The screen is preferably affixed within one or more transparent panels. In one embodiment, the screen may preferably have an arrangement with a number of wires having wire diameters in a selected weave or knitted pattern such that only between zero and eighty-five percent of the surface area of the screen is open area. The wire is preferably treated such that a desired level or amount metal luster is provided to control reflection/absorbtion properties of the screen. The screen may be utilized as building material such as walls, counters, shower enclosures, or to make other articles such as furniture.
