Appeal No. 96-1809
Application 08/094,724
Claim 1 is directed to a method of dispensing a liquid
sample onto a test element, the test element having a test
volume subtending a surface area for receiving the sample.
The method comprises:
a) “applying onto a transfer element having a
liquid-impermeable surface for supporting a liquid,”
a quantity of liquid sample over the supporting
surface, and
b) placing the transfer element supporting surface
“in contact with all of said surface area of a test
element at once,” thereby transferring substantially
all of the liquid sample as a surface-dispersed
quantity to the test element.
Harrison discloses an apparatus for applying liquid
samples to a surface. A dispensing device supports a series
of separate dispensing elements each comprising a closed or
substantially closed loop (34, 92) defining a reception area
for a film of solution (col. 3, lines 14-44). In operation,
the loop retains a film or droplet of solution which is
subsequently deposited on a sheet member by contacting the
loop with the sheet member (col. 4, lines 27-35). According
to Harrison, the dispensing elements may be formed from
resilient wire such as stainless steel spring wire bent into
