Appeal No. 1999-0752
Application No. 08/806,103
1. A fluid treatment device comprising:
a housing defining at least one chamber therein;
means for providing a fluid to said chamber of said
housing such that said fluid will provide chemical
action and will move through said chamber and be
maintained within said chamber at an established level,
said fluid including vortex regions of turbulent flow
within said device and a boundary layer region
immediately adjacent at least one of said vortex
regions and substantially not including vortices of
said fluid therein;
means for moving a substrate through said chamber of
said housing in an established direction along a path
of travel such that said substrate will be exposed to
both said vortex regions and said boundary layer region
of said fluid moving within said chamber for an
established period; and
means for providing vibrational energy to said fluid
moving within said chamber to enhance the treatment of
said substrate by said fluid by increasing said
chemical action by said fluid, said means for providing
vibrational energy positioned immediately adjacent said
means for providing said fluid along said path of
travel of said substrate and adapted for being partly
submerged within said fluid within said chamber and
being located adjacent said substrate as said substrate
moves through said chamber, said means for providing
vibrational energy focusing its vibrational energy at
said boundary layer region of said fluid not including
said vortices of said fluid therein while not being in
physical contact with said housing, said boundary layer
of said fluid being positioned substantially directly
below said means for providing said vibrational energy
along said path of travel and therefore immediately
adjacent said means for providing said fluid to said
chamber.
