  • Patent number: 4416940
    Abstract: Processes for the application of new water-reducible and solvent-based coatings to various substrates to simultaneously impart copper-like metal and patina coloration to achieve a simulated weathered copper appearance are described, as well as the articles produced thereby. The coatings are preferably applied to a primed metal substrate, especially coil coating stock, in a two-step process comprising a first application of a base coat containing a dominant patina-color-producing colorant followed by application of a top coat applied to the cured base coat, the top coat containing a copper-color-producing colorant. After final cure, the substrate exhibits both a copper metallic appearance by reflection of incident light from the top coat and a patina appearance by transmission of light to and reflection from the base coat.

  • Patent number: 4350529
    Abstract: A process is disclosed for improving the corrosion resistance of stainless steel powders produced by atomization in an oxidizing atmosphere whereby silicon present in the powder tends to form silicon oxides on the powder surface. The process comprises adding an effective proportion of a modifier metal selected from the group consisting of antimony, arsenic, and bismuth to the melt prior to atomization. The modifier metal addition is effective for decreasing the surface silicon oxides and thereby improves the corrosion resistance.

  • Patent number: 4347110
    Abstract: A system and apparatus are disclosed for removing particles from suspension in a liquid, particularly for removing tall oil soap particles from black liquor. The black liquor flows along a fluid flow path (10) which runs between a source of black liquor and a skimming tank. Two electrodes (16, 18) are disposed one downstream of the other within the fluid flow path (10). A power supply (26) applies an electrical potential between the electrodes (16, 18). The downstream electrode (18) is connected to earth ground (36). It has been found that this earth ground connection (36) provides substantial improvements in the quality and quantity of recovered tall oil soap.
