    Abstract: An air mixer, with a water collector, is disclosed for supplying recirculated cabin air in aircraft. In the preferred embodiment: used cabin air flows over pipes of colder fresh air to cool the used air and condense out most of the moisture contained in it; the fresh air and used air are passed over opposite faces of a ring of stator vanes, thereby imparting swirls to both types of airstreams; and the streams meet at the trailing tips of the stator vanes, where they corkscrew together to throw remaining coalesced moisture against a collection trough, from where it is discharged. The airstreams can now be injected into the cabin without droplets raining down on the passengers, nor ice clogging any pipes for the fresh air, which is typically supplied at below-freezing temperature.

  • Patent number: 4203736
    Abstract: A shell and two perforated cylindrical walls are radially spaced about a common vertical axis so as to define three coaxial spaces. A gas to be purified of suspended particles is admitted to the annular first space between the shell and a filter bed of granular material in the second space between the two perforated walls, and a purified gas is withdrawn from the third space. To clean the filter bed, granular material is conveyed from the lowermost portion of the second space through a conduit to a separating device above the topmost portion of the filter bed by a stream of conveying gas, and the gas entrains most of the particles from the granular material while the latter returns to the second space by gravity. The particle-laden conveying gas is introduced tangentially into the top portion of the annular first space where it is mixed with a scavenging gas passed through the filter bed from the third to the first space.

  • Patent number: 4199960
    Abstract: An accumulator for receiving a mixture of gaseous and liquid refrigerant fluid and liquid oil from an evaporator in an air conditioning system and for delivering only gaseous refrigerant fluid with oil atomized therein to the compressor. The accumulator has radially spaced telescoped straight lengths of tube to conduct the gaseous refrigerant fluid with oil atomized therein from the interior of the accumulator to the exterior thereof to thus eliminate the conventional U shaped tube for this purpose whereby the diameter of the accumulator may be smaller than the diameter needed to accommodate a U-shaped tube.The inner one of the telescoped tubes conducts gaseous refrigerant fluid from the top of the accumulator to the bottom end of the outer telescoped tube where it picks up oil from the bottom of the accumulator through a bleed port through the wall of the outer tube and then passes unwardly between the tubes to an outlet port at the top of the accumulator.

  • Patent number: 4076508
    Abstract: The disclosure concerns a separator for removing broken engine parts and other debris from the hot gases passing fro the exhaust manifold of an engine to the inlet of an associated turbocharger. The separator includes an annular separation chamber in which the gases are swirled by stationary vanes to effect centrifugal separation of the debris, and a cylindrical screen which filters the gases as they leave the separation chamber. The screen is mounted in cantilever fashion within the separator casing and carries, at its free end, the vanes and a deflector which directs inlet flow radially outward to the separation chamber. The vanes are freely mounted in slots formed in the screen, where they are held captive by the slot margins and the deflector, and the tips of the vanes are spaced radially from the surrounding casing of the separator.

  • Patent number: 4001121
    Abstract: A gaseous or liquid fluid to be centrifuged, for the purpose of purification or of separation of different phases, is conducted at high speed in a curved channel past a vortex chamber formed in one of the channel walls at the concave side thereof, this chamber being partly separated from the main fluid path by an overhanging sharp upstream edge and by a possibly rounded downstream edge which extend over the full width of the channel. A body of fluid whirling in this chamber develops a cylindrical core free from entrained solids, or from an accompanying heavier phase, which can be axially extracted from the chamber while the remaining fluid continues its flow through a reduced channel portion which may also be curved and provided with another vortex chamber to repeat the process. Entrained particles may be removed from the solid-enriched residual flow by way of end apertures along the periphery of the vortex chamber and/or at the convex side of the curved channel.
