  • Method of making a filter device
    Patent number: 6168681
    Abstract: A filter device filters contaminants from air for magnetic disk drive systems. The filter has layers of permeable fabric material allowing flow through the filter. An adsorptive slurry is deposited in a discreet pattern onto one layer with a cover layer mounted over the adsorptive deposit. The slurry retains a high adsorptive material surface area for improved adsorption of contaminants. The slurry is placed onto the base material using a screening or other similar application method.
    Type: Grant
    Filed: June 18, 1998
    Date of Patent: January 2, 2001
    Assignee: Donaldson & Company, Inc.
    Inventors: Cynthia D. Bellefeuille, Andrew J. Dallas, M. E. Wright, Michael A. Madden, Suzan K. Nunnink
