  • Cellular tumble coater
    Patent number: 5201956
    Abstract: An apparatus is disclosed for coating articles with a coating material by vapor deposition wherein a cellular fixture is employed for tumble coating the articles. The cellular fixture comprises multiple cells disposed radially about a common axis of rotation. The cells comprise hollow members having side walls with a plurality of openings therethrough to permit the flow of vapors of coating material, e.g. parylene, through the openings into the cells.

  • Removal of sulfur dioxide from gas streams
    Patent number: 5202103
    Abstract: Processes are provided for the removal of sulfur dioxide from gas streams using aqueous lime or limestone slurries containing an additive comprising an amine. The amines have an available alkalinity of at least 0.5 meq/gram at a pH between 3.0 and 5.5. The amines are highly soluble in the slurry and can have a low volatility, thereby reducing amine losses with the gas product. Furthermore, amines which are absorbed on the calcium sulfate or calcium sulfite by-products can be recovered by water-washing with a water make-up stream.
