  • Patent number: 4508787
    Abstract: A protective coating which is resistant to attack by basic solutions is formed from interpolymers containing maleic anhydride (MAH). An article is coated with a solution of the dissolved ammonium or amine salts of the MAH interpolymer, or if the article itself contains MAH the salts may alternatively be formed on the surface of the article by applying a basic solution containing the ammonium or amine ions. The article is then dried and heated at a temperature sufficient to form the cyclic imide structure from the ammonium or amine salt of the MAH, typically about 160 to 200.degree. C.

  • Patent number: 4422303
    Abstract: A continuously controlled process for cooling a material to within a desired temperature range as the material moves along a path, especially suitable for situations in which the amount of material being cooled is unknown. The material is first contacted with a known amount of cooling liquid, e.g., water. The temperature of the water (or steam) is measured after contact with the material, and this information is then used to determine the amount of additional cooling required. An embodiment utilizing the process to cool calcined coke in a rotary cooler is described.

  • Patent number: 4416690
    Abstract: Copper sulfide ores are processed by a unique series of steps to produce blister copper, while attaining long sought advantages. An initial smelting step is carried out in any desired manner, e.g. according to conventional practice, to produce a molten, copper sulfide matte or white metal. This matte or white metal is then solidified and subjected to a size-reduction step to produce solid particles capable of being injected into a converting vessel in a stream of oxygen, either pure oxygen or air significantly enriched with oxygen. With the matte or white metal injected in this manner, the converting reaction may be carried out on an autogenous basis, with continuous evolution of substantially undiluted SO.sub.2 gas capable of being liquified for use in the production of elemental sulfur or sulfuric acid or for disposal so as to avoid atmospheric contamination.

  • Patent number: 4410659
    Abstract: A process for the impact modification of a plastic with a rubbery polymer to form a thermoplastic resin in a reactor extruder is provided. The process includes the steps of dissolving a rubbery polymer in at least one ethylenically unsaturated monomer to form a feed solution, introducing the feed solution into the feed section of a twin screw reactor extruder, heating the feed solution under pressure to a temperature sufficient for polymerization to begin, shearing the feed solution until the solids content formed is equal to at least about twice the rubber content in the feed solution so as to produce a phase inversion product wherein discrete particles of rubber become encapsulated in a continuous phase of plastic polymer formed from the ethylenically unsaturated monomer, thereafter reacting the phase inversion product until at least about 70 weight percent of the feed solution has been converted to a thermoplastic resin, and extruding the said thermoplastic resin through a die.
