    摘要： A self lubricating bearing for use submerged in cryogenic fluids. The self-lubricating bearing comprises hardened races, hardened rolling elements and polymeric retainers or cages. More particularly, the rolling elements may be hardened balls, and the polymeric cages may include PEEK. In particular a bearing for self lubricated use in seal-less, magnetic drive pump for pumping fluids at very low temperatures and cryogenic temperatures below about −100 degrees centigrade such as liquid nitrogen and temperatures below about −150 degrees centigrade such as liquefied natural gas (LNG). An environment for submerged use of such a bearing may be a magnetically driven cryogenic pump with a housing having an intake and exhaust with a back plate mounted therein in which a shaft is journaled in self-lubricating bearings having hardened stainless steel or ceramic balls, stainless steel races and polymeric retainers or cages for retaining the balls for rolling contact in the races. An impeller is mounted on the first end and a first magnet is mounted on the second end of the shaft.

    摘要： In a variable displacement type hydraulic pump/motor assembly including at least one internally movable component, such as a yoke, a swashplate, and the means for moving the swashplate, the improvement includes imparting on this component absolute location indicia markings and the addition of an optical/electronic sensor unit capable of reading such indicia markings fixedly located on a housing of the pump/motor assembly and including an optical read head extending into the housing interior and located at a spaced distance from the indicia markings for reading same, relative to a reference location, and producing a signal indicative of the absolute position of the movable component. The signal can then, in turn, be used for controlling the displacement of the pump/motor assembly. A method for determining the absolute component position is also set forth.
