  • Control process for impregnating porous parts and apparatus therefor
    Patent number: 6534115
    Abstract: A process for impregnating at least one porous part with an impregnant is provided comprising: (a) immersing the porous part(s) in impregnant; (b) measuring at least one parameter indicative of the buoyancy of the porous part(s) as the impregnant impregnates the parts; and (c) interrupting impregnation when the measured parameter(s) indicates a predetermined level of impregnation is achieved. An apparatus for impregnating porous parts comprises a vessel for holding the porous part(s) and an impregnant, and a measuring device for measuring at least one parameter indicative of the buoyancy of the porous part(s) immersed in the impregnant within the vessel.
    Type: Grant
    Filed: June 29, 2001
    Date of Patent: March 18, 2003
    Assignee: Ballard Power Systems Inc.
    Inventors: Emerson Richard Gallagher, Paul Po Hang Fong, Oliver Clemens, Horst Thumm, David Brown

  • Control process for impregnating porous parts and apparatus therefor
    Patent number: 6299933
    Abstract: A process for impregnating at least one porous part with an impregnant comprises: (a) immersing at least one porous part in a fixed volume of impregnant, (b) measuring at least one parameter indicative of the effective volume of the impregnant as the impregnant impregnates the porous part(s), and (c) interrupting impregnation when the measured parameter(s) indicates a desired level of impregnation is achieved. An apparatus for impregnating porous parts comprises a vessel for holding at least one porous part and a fixed volume of impregnant, and at least one device for measuring the change in effective volume of the impregnant within the vessel.
