Title: Dual labyrinth fluid seal with fluid slinger
Inventor: AMDALL JOHN
IPC: F16J15/447
Filed: 1982-12-10
Granted: 1988-01-14
Abstract: A non-contacting seal (30) is at an operative interface (16), e.g. between an engine crankcase and crankshaft, located in the stationary part.  A second non-contacting seal (40) at the operative interface is located in the rotary part, adjacent and in series with the first seal, which is located between a fluid chamber (e.g. the oil sump) and the second seal. The first seal can be of labyrinth type, with a series of annular grooves.  The second seal is a spiral groove, to direct leakage oil back to the sump during rotation.  A drain for removing any oil build-up can be located between the seals.

Title: Apparatus and method for extracting liquid from a humid mass by compression
Inventor: BARBULESCU ADRIAN
IPC: B30B9/02
Filed: 1983-05-31
Granted: 1988-06-23
Abstract: The present invention relates to a system and a method of extraction liquid from a humid mass by compressing same. The system comprises a conduit of linear, circular or other shape through which the humid mass is displaced. The conduit is of rectangular cross-section, which cross-section can be constant or variable. Further, the conduit has perforated side walls along at least a liquid extraction working section of the conduit. The system further comprises elements which cause an axial pressure at the interior of the humid mass as well as a mechanism to displace at least one of the perforated side walls to convey the humid mass along the working section of the conduit in such a way as to generate between the interior surface of the perforated side walls and the humid mass a dynamic friction force which defines a pressure zone which is less than the axial pressure created by the pressure creating elements. This difference in pressure causes the liquid in the humid mass to flow out of the mass in a direction substantially transverse to the displacement direction of the humid mass and out through the perforated side walls of the conduit.

Granted: 1989-04-20
Abstract: A screw rotor machine for compressing air or other working fluid comprises a housing (11) including two intersecting bores axes which together define a working space (14). The pair of intermeshing rotors (22, 23) are rotatably mounted one in each bore. The rotors have helical lands and intervening grooves whereby rotation of the rotors in connecting engagement is effective to compress the working fluid (or to expand the fluid if the machine is used as an expander). A low pressure port (16) and a high pressure port (19) formed in the housing at opposite ends thereof permits inlet and outlet of the working fluid. The grooves (28, 34) of the rotors each have a primary flank (31, 37) and a secondary flank (32, 38). The tips of the primary flanks of both the male and female rotors are formed by parabolic arcs which generate major portions of one of the flanks of the opposite rotors. A major portion of the secondary flank of the female rotor is also a parabolic arc.

Granted: 1989-11-23
Abstract: A railroad freight car having a rotatable loading floor for transferring loads between it and a station platform. The railroad station has two platforms on opposite sides of the rail car. An edge of each platform is provided at each longitudinal end with a sloping beam which angles upwardly from the end of the platform towards its center. The lowest part of the beam, which is at the free end of the platform, is below a set of wheels carried on the chassis of the rail car. The center portion of the platform is at a height above that of these rollers. The rollers are arranged to extend laterally of the rail car and to overlie the beams. As the rail car pulls into the station, the rollers will engage the upwardly sloping part of the beams to thereby raise the chassis in relation to its wheels by virtue of extending the suspension as the car continues in its direction of movement. The chassis is, thus, brought into a suitable level to enable the loading floor to freely rotate to overlie the station platform and, thereby, enable the loading and/or unloading operations to take place.
