DEFINITION

Classification: 205/674

Electrolyte composition or defined electrolyte:

(under subclass 640) Subject matter drawn to (a) electrolyte compositions, (b) processes of preparing an electrolyte of specified composition, or (c) electrolytic erosion processes which employ an electrolyte of specified composition.
