Abstract: Disclosed is a production method of an aluminum support for a lithographic printing plate, capable of stable and low-cost production of an aluminum support for a lithographic printing plate, the support being scarcely subject to generation of treatment unevenness called streaks or grainy unevenness ascribable to the different in the aluminum dissolving rate due to the difference in the orientation of the crystal grain. The aluminum support is produced by surface graining and then polishing an aluminum plate or by polishing an aluminum plate while etching it in an aqueous acid or alkali solution. The aluminum plate may be subjected to polishing and then to anodization or may be subjected to polishing, to surface graining, again to or not to polishing and then to anodization. A production method for producing a high-quality support for a lithographic printing plate, free of local unevenness is also disclosed.

Abstract: A method and an apparatus for manufacturing a wire, particularly a sawtooth wire for all-steel sawtooth wire card clothings, wherein the surface of a wire-shaped intermediate product, such as a wire already provided with sawteeth, is smoothened in an electropolishing process in an electrolyte bath containing an electrolyte. A relative movement is produced between the electrolyte and the intermediate product during the electropolishing process. The apparatus includes a device for producing a relative movement between the electrolyte and the intermediate product contained in the electrolyte bath.

Abstract: A method of producing fluids from a well bore by polishing the inside diameter surface of a down-hole tubular. The method includes the steps of providing a down-hole tubular having an inside diameter and being made of a carbon steel alloy or a high chromium alloy, preparing an inside diameter surface of the down-hole tubular, subjecting the inside diameter surface to an electropolishing treatment to produce a smooth surface being slick and essentially non-stick, locating the down-hole tubular within the well bore adjacent a fluid-producing formation, and producing the fluids through the inside diameter of the down-hole tubular. The electropolishing treatment can also be applied to the inside diameter surfaces of carbon steel drill pipe.

Abstract: In a process for producing an aluminum support of a lithographic printing plate, the desired aluminum support is produced by imparting fine asperities to an aluminum plate and then roughening it electrochemically in an acidic aqueous solution. The roughened aluminum plate may be electropolished or chemically etched.

Abstract: The present invention teaches a method of producing a textured surface upon an arbitrarily configured titanium or titanium alloy object for the purpose of improving bonding between the object and other materials such as polymer matrix composites and/or human bone for the direct in-growth of orthopaedic implants. The titanium or titanium alloy object is placed in an electrolytic cell having an ultrasonically agitated solution of sodium chloride therein whereby a pattern of uniform "pock mark" like pores or cavities are produced upon the object's surface. The process is very cost effective compared to other methods of producing rough surfaces on titanium and titanium, alloy components. The surface textures produced by the present invention are etched directly into the parent metal at discrete sites separated by areas unaffected by the etching process. Bonding materials to such surface textures on titanium or titanium alloy can thus support a shear load even if adhesion of the bonding material is poor.

Abstract: A process and apparatus for the continuous treatment of annealed and non-annealed hot strip of stainless steel. First, the hot strip is stretched, bent and straightened to break a scale which has grown on the hot strip. Then, a electrolytic pickling is performed in an electrolyte with multiple alternating anodically-connected and cathodically-connected strip polarization. Directly following thereafter, pickling once again takes place in the electrolyte with multiple anodically-connected electrodes arranged directly behind one another and corresponding cathodic strip polarization, followed by anodic strip polarization produced by means of a cathodically-connected electrode. To further remove any scale remaining on the surface of the hot strip, the hot strip is subject to high-pressure fluid spraying or brush aggregates. Renewed electrolytic pickling in performed with at least one electrolyte with multiple exclusively cathodically-connected electrodes and anodic strip polarization.
