application, have been withdrawn from consideration. Claim 16
is illustrative:
16. An environmentally safe method of repairing a
previously conversion coat solution treated surface using said
conversion coat solution and minimizing waste produced in the
repair process, wherein said conversion coat solution includes
chromic acid and cyanide, comprising the steps of:
providing an applicator having a reservoir and a liquid
dispensing tip coupled thereto, said applicator being made
from a material which does not react with said conversion coat
solution;
disposing an amount of said conversion coat solution in
the reservoir;
sealing the reservoir to confine said conversion coat
solution therein;
placing the liquid dispensing tip in contact with a
desired area of the surface; and
rubbing the tip over the desired area of the surface to
dispense a controlled amount of the conversion coat solution
onto the desired area;
placing a tip cover over the dispensing tip to prevent
inadvertent application of the conversion coat solution;
whereby the conversion coat solution dispensed on the
desired area of the surface dries on the surface leaving
substantially no wasted solution.
In addition to the admitted state of the prior art found
in appellant's specification, the examiner relies upon the
following reference as evidence of obviousness:
