(under subclass 368) Subject matter wherein the lubricant is
supplied to a bearing surface by pressure.
(1) Note. Included are pump systems and bearings grooved, or otherwise altered so that lubricant under pressure can be supplied to the bearing surface, a reservoir, or pressure normally produced by rotation of a shaft is not proper for this subclass.
(2) Note. If the lubricant supports one of two relatively rotating elements to the extent that there is positive clearance between them in operation, the patent is in subclasses 100+.
