Appeal No. 95-4081
Application 08/071,895
The product is said to be a "borate ester of the reactant
phosphorodithioate" (col. 4, lines 19-21).
16. According to Braid, the product of his
invention, i.e., the borate esters, may be used in industrial
fluids, such as lubricating oils (col. 3, lines 51-52). The
lubricating oils may be further compounded by thickeners to
produce grease compositions (col. 3, lines 61-63).
17. Lubricating compositions containing the borate
esters described by Burjes are said to have "excellent
inhibition and antioxidant stability by the additive of this
invention" (col. 3, lines 67-69).
18. Braid notes that (col. 2, lines 1-5; emphasis
added):
The products of this invention are esters which are
strikingly effective as anti-corrosion agents and
antioxidatants in industrial fluids, especially in
lubricating oils. These esters are particularly
effective in preventing corrosion of copper surfaces.
19. Braid further notes that (col. 5, lines 48-54):
The products of this invention may be used in
lubricating oils, fuels and other industrial
compositions, both liquid and solid. These compositions
may contain other additives which provide additional
