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 bonded with phosphate ion.
