Abstract: A compressor system including a compressor airend having an inlet and an outlet and operable to discharge a mixed flow of fluid including a working fluid and a lubricant. A separator receives the mixed flow of fluid and discharges a primary flow of lubricant, a secondary flow of lubricant, and a flow of compressed working fluid. An acid filter includes a fluid inlet positioned to receive the secondary flow of lubricant.

Abstract: A fuel assembly mechanical flow restriction apparatus for detecting failure in situ of nuclear fuel rods in a fuel assembly during reactor shutdown.

Abstract: An inlet valve for use in a gas compressor, the inlet valve including a piston movable within a housing chamber toward and away from a housing inlet and a valve disc movable with the piston, the valve disc including an aperture for selectively providing air flow from the housing inlet into the chamber, and a flexible member engageable with the valve disc to close the aperture. The inlet valve also includes a valve seat disposed near the housing inlet, and the piston is movable between a first position where the valve disc contacts the valve seat, and a second position where the valve disc is spaced from the valve seat. A spring biases the valve disc toward the valve seat.

Abstract: An oil scavenger system for a face seal including a lubricant scavenger system for retrieving lubricant which has escaped from a first side to a second side of a seal which seals a rotary shaft. The rotary shaft is used on a compressor, pump, or any other machine which involves a lubricant seal about a rotary shaft. A cover encases the second side of the seal, producing a first space therebetween. A first pressure is maintained in the first space. A second space is interconnected to the first space whereby the lubricant may freely pass therebetween. The interconnection may be mounted exterior or interior of the machine. A second pressure is maintained in the second space than in said first space. The second space may actually be in communication with the first side of the seal. The second pressure is less than the first pressure.
