  • Patent number: 9988549
    Abstract: Disclosed is a water-soluble coating composition, which is applied on the surface of fuel rods to prevent scratching of the surface of the fuel rods upon manufacturing a nuclear fuel assembly for light water reactors. This water-soluble coating composition facilitates the formation and removal of a coating film and the resulting coating film can exhibit strength and durability equivalent to those of an existing lacquer (nitrocellulose) coating film, and can thus be used as an alternative to lacquer, thereby easily removing the coating film and improving workplace safety, ultimately achieving improvements in the working environment and high workplace safety.

  • Patent number: 7485588
    Abstract: This invention relates to textile substrates to which a finishing treatment has been applied during the manufacturing process. Such a finishing treatment provides improved water and/or oil repellency and stain and soil resistance. The finishing treatment generally includes a repellent agent, a stain release agent, and a particulate component. Other compounds may be added to the treatment, such as stain-blocking agents, crosslinking agents, coupling agents, antimicrobial agents, and pH adjusting agents. The components of the finishing treatment are generally applied to the textile substrate using an application process that results in layered structures on the surface of the treated substrate, which has been found to greatly improve the durability of the treatment. Such treated textile substrates thus exhibit excellent stain and soil resistance and water and/or oil repellency properties.

  • Publication number: 20020106453
    Abstract: The invention is a method for treating a worksurface of a workpiece to render it static dissipative under conditions of low relative humidity. Conditions are created that render the worksurface receptive to treatment with a electrostatic dissipative (ESD) agent. The receptive worksurface is contacted with an ESD agent. Finally, the conditions created to render the worksurface receptive are removed. One method for treating a worksurface of a workpiece to render it static dissipative under conditions of low relative humidity commences by contacting the worksurface with an aqueous bath comprising acid and poly(3,4-ethylene-dioxythiophene)-poly(styrenesulfonate). The worksurface is removed from the bath and excess bath is washed away from the worksurface. The worksurface finally is dried. The preferred acid is HCl. Another method involves heating the worksurface to render it receptive followed by treating with heated worksurface with the ESD agent and subjecting the treated worksurface to pressure.

  • Patent number: 6214421
    Abstract: A method of powder coating at least one surface of a non-conductive object having a plurality of sequential steps. The first step is pretreating the surface of the non-conductive object to ensure that the surface is suitably cleaned. The second step to apply a sufficient quantity of moisture on the surface of the non-conductive object to facilitate adhesion of a powder coating to the surface. The next step is to spray a polymer coating powder on the moistened surface of the non-conductive object. This spraying step is done immediately following the application of moisture but prior to a complete evaporation of the applied moisture. The fifth step is to evaporate any remaining applied moisture from the non-conductive object prior to curing. The last step is to cure the coating on the surface of the non-conductive object without decomposing the powder and then either cool or allow the non-conductive object to cool naturally.

  • Patent number: 4325993
    Abstract: The present invention relates to a process for preserving wood, in particular hardwoods, against attack by living organisms, e.g. fungi and insects, which destroy wood. In particular, the present invention provides a one or two step process for preserving wood against fungal and/or insect attack. The fungicide treatment step comprises introducing a copper solution or a copper solution into wood. The insecticide treatment step comprises introducing a chromium and arsenic solution into wood. If the pH of the wood system is controlled, both steps may be carried out simultaneously so as to preserve the wood against fungal and insect attack. Alternatively, the insecticide treatment step may follow the fungicide treatment. Where only protection against fungus is desired, the process comprises introducing copper and arsenic solution into wood. On the other hand, if only an insecticide treatment is required, the process comprises only the abovementioned insecticide treatment step.

  • Patent number: 4284660
    Abstract: A method is disclosed for preventing stress corrosion cracking or metal embrittlement of a zirconium or zirconium alloy container that is to be coated on the inside surface with a layer of a metal such as copper, a copper alloy, nickel, or iron and used for holding nuclear fuel material as a nuclear fuel element. The zirconium material is etched in an etchant solution, desmutted mechanically or ultrasonically, oxidized to form an oxide coating on the zirconium, cleaned in an aqueous alkaline cleaning solution, activated for electroless deposition of a metal layer and contacted with an electroless metal plating solution. This method provides a boundary layer of zirconium oxide between the zirconium container and the metal layer.

  • Patent number: 4261722
    Abstract: Inorganic coatings for glass surfaces, especially hot end coatings for glassware, are produced by applying vapors of thermally decomposable metal compounds such as stannic chloride to the surface of glass at an elevated temperature and maintaining in a zone adjacent to and in close proximity to the heated surface a region of elevated moisture content. In a preferred form, separate streams of metal compound vapor and water vapor are directed onto the surface of the heated glass.

  • Patent number: 3949124
    Abstract: There are provided novel antistatic carpet yarns and carpets as well as novel compositions of matter and methods for the chemical treatment of carpet yarns and carpets in order to impart to such textile materials substantially durable hydrophilic, soil-repellency and antistatic properties that will be retained despite rigorous exposure to washing, foam, vacuum and steam cleaning, and wear under high compression loads (or foot-traffic), without any adverse effect on dyestuffs or flammability. The method consists essentially in first treating the carpet yarn or carpet made of preferably synthetic fiber material (by such per se well known methods as padding, spraying or transfer-roll) with an aqueous emulsion which forms a normally solid coating consisting essentially of:A. at least one phase of an alkylphenol which is insoluble in water and which is dissolved in an alcohol, a ketone, or other organic solvent;B.

  • Patent number: RE35879
    Abstract: The apparatus, system and method utilize sequential sprays of wet, low-temperature steam, and dry, high-temperature steam to clean the exterior of laminated objects as well as to effect volatilization of liquid contaminates trapped between lamina thereof. Water is injected into the conduit through which the low-temperature steam is delivered, so as to produce a desirable concentration of droplets therein. A conveyor moves the laminated objects along a horizontal path through zones in which they are sprayed by the low temperature and high temperature steam, and then through a zone in which they are electrostatically coated with powder.
