Abstract: Sound attenuating liquid-gas separation apparatus includes nested elements which are tuned to abate noise in general and at predetermined frequencies in particular in a screw compressor assembly. The apparatus includes a helical flow path defined internal of an outer shell. The shell is selectively perforated at its downstream end to allow for the egress of separate oil from it. The apparatus includes a columnar, open-ended cylindrical member internal of the outer separator shell and a discharge conduit which penetrates both the separator shell and the open end of the columnar cylindrical member disposed within the shell to create the nesting which both contributes to the oil separation proces and abates noise. By selectively dimensioning and therefore "tuning" the nested members in accordance with the characteristics of the particular compressor with which they are used, compressor assembly noise abatement at predetermined frequencies is accomplished.

Abstract: The present invention relates to improvements in centrifugal separators of the cyclone type, in which the liquid or gaseous fluid to be purified passes through an inlet blading which is shaped so as to cause the fluid to whirl rapidly in so-called irrotational flow with uniform longitudinal lamellar components, around a high voltage electrode. An outlet device firstly comprises a convergent portion which partly converts the energy of whirling into energy of longitudinal translation, then a blading which completes the conversion, and finally a divergent portion in which the excess of dynamic energy of flow is converted into static pressure in order to recover as much as possible of the whirling energy applied to the fluid upstream of the inlet of the cyclone device. The separated particles are evacuated through a tangential outlet. The invention is more particularly applicable to the purification of fluids.

Abstract: The invention is a device which provides for separation of contaminants from a relatively high velocity stream of gas. The invention provides a first stage wherein the gas stream is decelerated and the contaminant particles are caused to separate from the air stream by interacting with a first surface. The interaction results in the particles to acquire a radial velocity vector and by virtue of the momentum of the contaminants particles. The contaminant particles are forced to the outer layer of the gas stream. The second stage of separation provides for further magnification of the radial velocity vector and also induces a slight tangential velocity component to the contaminant particle. By impacting the contaminants against a vane mounted within the gas stream, the contaminant particles, as a result of this impact, acquire a slight swirl or circular motion which causes the contaminant particles to be more localized.

At the inlet, this recycled steam is drawn into the separator by way of an ejector-type recycle pump.

Abstract: Jet engines can function properly even in conditions where liquid droplets are taken in by the compressor of the engine. However, where the droplets contain corrosive substances such as salts, damage can accrue not only through corrosion, but through build up of deposits spoiling the aerodynamic flow of air and gas through the engine. The risk of this ocurring is reduced by placing a vaned vortex generator in the intake and including on the flanks of its vanes, grooves which collect the droplets into coalesced streams and directs them to an area adjacent the intake wall. A flow splitter provides an annular, secondary outlet to dump the concentrated fluids.
