Appeal No. 1996-2928
Application 08/313,727
THE INVENTION
The invention is directed to a high pressure lubricant additive. The additive consists of a
composition containing phosphorous and diamines characterized by a C - C fatty acid residue12 22
RCOO having at most one fatty acid residue per two zinc units, wherein the zinc is bonded with-
phosphate ions.
THE CLAIMS
Claim 1 is illustrative of appellants’ invention and is reproduced below.
1. A high pressure lubricant additive comprising complex compound suitable for use in a high
pressure additive to facilitate lubrication of metal surfaces, containing phosphorous and diamines and
dispersible in oils or oil emulsions, characterized in that it consists of a composition containing a C -C
12 22
fatty acid residue with at most one fatty acid residue group (RCOO) per two zinc atoms and zinc is
