Abstract: The invention relates to a system for detecting the defects of a wall used for enclosing a space where—generally liquid—materials are stored, with a coating on its internal side, especially a container wall, or/and the defects in the coating. In numerous fields of life all types of different materials, such as chemicals, solvents, petroleum oil and petroleum fractions, etc. need to be stored in a way excluding the possibility of these materials getting into the environment or other materials from the environment intermixing with the stored materials. In most cases such materials are stored in containers made of different materials, mostly metal, the walls of which holes may appear either as a result of corrosion or other damage, and through the appearing holes materials can flow either from outside into the container or from inside the container into the environment, and so the stored material may become unsuitable for use or serious environmental pollution may occur.

Patent number: 6902761
Abstract: The invention relates to a method for the interior metal-coating of glass tubes, with the metal-coated surface being a cylindrical shell. In accordance with the invention such a method comprises the following process steps: the glass tube is sealed off at either end; the glass tube is brought to a horizontal position: a sensitizer solution is introduced into the interior space of the glass tube in such a quantity that the interior space is only partly filled; the sensitizer solution is removed from the interior space after a certain dwell period; a mirror-coating solution is introduced into the interior space of the glass tube, with the entire interior surface of the glass tube being wetted by the mirror-coating solution; the used-up mirror-coating solution is removed from the interior space of the glass tube.

Patent number: 6841194
Abstract: A process for applying a graphite coating to the interior of a prismatic battery can by filling the can with a slurry containing graphite particles, immediately removing the slurry with an aspirating nozzle and then drying the residue left in the battery can to leave a thin film of graphite on the interior of the can. In a continuous process, fill nozzles and aspirating nozzles are moved in set into and out of the cans simultaneously, while moving the nozzles along with the cans through a fill and aspirate station on a conveyor. From there the cans travel through a drying oven where the residue remaining in the cans is dried to leave a thin uniform graphite film inside a prismatic can.

Patent number: 6602541
Abstract: A process for depositing an antimony-containing coating upon a surface of a heated glass substrate includes dissolving an antimony halide in an organic solvent to form an antimony halide containing solution. This solution is then vaporized to form a gaseous antimony precursor. The gaseous antimony precursor is then directed toward and along the surface of the heated glass substrate. The antimony precursor is reacted at or near the surface to form an antimony containing coating.

Patent number: 6565915
Abstract: In a method for lacquering the inner side of a display screen, a frame is provided to form sealing means for sealing a spacing between a closing means having a passage and closing an inner space of a lacquering head at the top and a display screen covering this passage, in which method an air gap formed between the frame and a peripheral area of a display screen extending substantially parallel to a display screen axis and being bounded by an outer peripheral boundary face constitutes a flow resistance as a result of its dimensions and counteracts the escape of a gaseous medium from the inner space of the lacquering head and through the spacing between a passage boundary face of the passage in the closing means and the outer peripheral boundary face of the peripheral area of a display screen covering the passage in the closing means.

Abstract: An improved shaft is described with which a sponge saturated with carbon coating can be pushed through the narrow neck of a cathode ray tube funnel to fully coat the interior of the neck with the carbon coating. The improved shaft is made of a plastic composite material. The preferred material for the improved shaft is garolite. This improved shaft is much less expensive that previous stainless steel shafts and has enough flexibility that it is not easily bent when plunged into a funnel that is not properly aligned and centered under the shaft.

Application number: 20020121441
Abstract: An automotive lambda oxygen sensor is formed by electroless plating of a thin, catalytically active, conductive electrode uniformly on the outer surface of a zirconia thimble. The process includes forming a pristine zirconia solid electrolyte thimble and drilling out a cylindrical cavity in it. A porous outer surface suitable for producing crystallization sites is formed by dipping the unfired thimble in a zirconia slurry containing spray-dried microspheres and firing the coated thimble to densify the thimble and the microspheres and to produce cavities on the surface of the thimble. An inner platinum electrode is formed by conventional conductive ink painting on the axial cavity of the sensor, and the sensor is again fired. The surface is activated by immersion in an acetone chloroplatinic acid bath to form multiple crystallization points, heat treated, then plated in an electroless platinum bath to a desired thickness.

Patent number: 6440284
Abstract: The present invention provides methods of electrophoretically separating macromolecular species, as well as compositions and systems useful in carrying out such methods. Specifically, the methods of the present invention comprise providing a substrate that has at least a first capillary channel disposed therein. The surface of the channel has a first surface charge associated therewith, and is filled with a water soluble surface adsorbing polymer solution that bears a net charge that is the same as the charge on the capillary surface.

Patent number: 6406742
Abstract: A coating apparatus for forming a high-resistance film on the inner surface of the neck of the funnel of a cathode ray tube has a nozzle that can be inserted into the neck. The nozzle, which is provided for applying a material liquid to the inner surface of the neck, has a jet hole inclined toward the direction of gravity. The material liquid applied through the jet hole thus inclined scarcely flows upwardly on the inner surface of the neck. The liquid therefore forms a high-resistance film having a uniform thickness on the inner surface of the neck of the funnel. Having a uniform thickness, the high-resistance film inhibits the charge-up of the neck potential, reducing the convergence drift caused by the charge-up of the neck potential.
