  • Patent number: 4620913
    Abstract: An improved method and apparatus for maintaining cathode spots in an electric arc vapor deposition coating process, on the desired cathode evaporation surface are disclosed. A primary anode is arranged, configured and biased within a vacuum deposition coating chamber relative to a cathodic source so as to maintain an electric arc therebetween. A relative biasing network maintains a voltage difference during deposition between the primary anode and other conductive surfaces within the chamber, or the chamber wall itself, such that electrons leaving the cathode are preferentially drawn toward the primary anode rather than to other conductive surfaces. The anode orientation within the chamber causes those electrons drawn toward it to tend to maintain the cathode spots on the desired cathode evaporation surface for maintaining arc stability at low arc current levels.

  • Patent number: 4615781
    Abstract: The present invention provides a means of relieving stress on an apertured mask, typically used to deposit thin-film structures on a glass substrate, such that the mask easily conforms to the substrate surface when the mask is in its hold down and patterning position during the deposition process. In particular, the present invention provides a mask assembly having a structurally relieved inner apertured mask portion from an outer mask portion that serves to eliminate wrinkles or crimps in the mask during deposition which may produce unacceptable blurs or shorts between thin-film structures. The stress relieving feature includes a slot which is disposed peripherally about the inner mask and two small segments providing the interconnection between the inner and outer mask of the mask assembly.

  • Patent number: 4615780
    Abstract: A continuous method is presented for removing both oxides of sulfur and oxides of nitrogen from combustion or exhaust gases with the regeneration of the absorbent. Exhaust gas is cleaned of particulates and HCl by a water scrub prior to contact with a liquid absorbent that includes an aqueous solution of bisulfite and sulfite ions along with a metal chelate, such as, an iron or zinc aminopolycarboxylic acid. Following contact with the combustion gases the spent absorbent is subjected to electrodialysis to transfer bisulfite ions into a sulfuric acid solution while splitting water with hydroxide and hydrogen ion migration to equalize electrical charge. The electrodialysis stack includes alternate layers of anion selective and bipolar membranes. Oxides of nitrogen are removed from the liquid absorbent by air stripping at an elevated temperature and the regenerated liquid absorbent is returned to contact with exhaust gases for removal of sulfur oxides and nitrogen oxides.

  • Patent number: 4610775
    Abstract: A method and apparatus for vaporizing any flakes of sputtering target material which short circuit high voltage cathodes during the sputtering of a coating on a substrate such as nuclear fuel pellet positioned in the vacuum chamber of a sputtering device. A separate low voltage, high current auxiliary power source is used to evaporate the shorting flakes. The present method and apparatus reduces the process recovery time in the event of a shorting flake from as long as 6 hours down to as little as 5 minutes without compromising the purity of the sputtered coating. The auxiliary power source may be an ac source which is preferably connected in series with the shorting flake so that current from the ac source will cease as soon as the shorting flake is evaporated. A ballast and/or short circuit indicating device may also be provided in series with the ac source in order to limit the ac current and in order to indicate the presence of shorting flakes.

  • Patent number: 4610806
    Abstract: Fluorescamine or like compounds react with the epidermis when applied to the skin and form, within about 15 to 30 minutes after application to the skin, a long-lasting reaction product, which is invisible in ordinary light but which fluoresces intensely under ultraviolet light. Such markings resist removal by abrasion and repeated washings. Organic solutions of such compounds, preferably containing a fugitive dyestuff or pigment and used as the marking fluid of a conventional felt-tipped pen, can be used to mark skin for radiological or diagnostic purposes. Inanimate objects can be coated with these compounds to detect human contact therewith.
