Abstract: In a pressurized materials processing system, separation of solid particulates from a gaseous process fluid is beneficially accomplished by use of a swept orifice discharger comprised of a cylindrical housing that is closed at one end and open at the other end. The housing contains an impeller within its interior and has a selected, presized orifice in its cylindrical side wall. In operation, the solid material and gaseous fluid are received in the swept orifice discharger housing and the solid material is continuously centrifugally urged toward the housing side wall so that it separates from the gaseous process fluid and collects on the housing side wall.

Abstract: A method and apparatus for separating, spreading and distributing a solid or liquid particulate material. The particulate material is pneumatically conveyed into a centrifugal chamber within a rotor (20) operatable by the flow of material for centrifugal separation of the particulate material. The terminal edge of the circumference of the centrifugal chamber serves as an overflow for establishing a buffer store and has a flow-retarding inwardly directed flange. A baffle may be provided around the terminal edge to intercept the material flung out and to conduct the material, via hopper-like flow-retarding recesses, to different outlets provided around the terminal edge.

Abstract: An improved centrifugal separator for vapor-liquid mixtures having a vertical upflow conduit closed at the top end and open at the bottom end. A plurality of curved arms similar in shape to a truncated torus of rectangular cross-section penetrate and extend within the conduit at its upper portion. A second plurality of curved arms are located immediately below the upper group and are contiguous thereto. The vertical upflow conduit has a lesser internal diameter in the lower portion, interconnected with a greater internal diameter portion in the upper portion by a frusto-conical section.

Abstract: A device for separating gas mixtures having different molecular weights iudes a cylindrical central body having longitudinal deflection channels formed in a circumferential surface with a plurality of elongate separating elements being grouped about the periphery of the central body with each of the separating elements being formed on the side of each separating element facing the central body with a pair of tapered legs defining therebetween a concave prismatic channel. Each of the tapered legs extends into a deflection channel of the central body and terminal edges of the legs operate to generate a nozzle effect.

Abstract: A tube receives a liquid-gas mixture into a first end. Blades are mounted at the first end of the tube and the gas-liquid mixture impinges on the blades and is directed by the blades into a vortex within the tube. Openings in the tube wall conduct the liquid thrown against the interior of the wall into a casing formed over the wall openings. The gas, separated from the liquid, is passed from the second end of the tube while the liquid separated from the gas and collected in the annulus between the external wall of the tube and the casing over the wall openings is discharged.

Abstract: A vacuum system includes a vacuum pump, means to provide a flow of lubricant oil to the vacuum pump, and an oil reclaimer and muffler assembly to remove oil that becomes entrained in the gas stream leaving the pump and to permit such oil to be resupplied to the means providing the flow of lubricant to the pump. The oil reclaimer and muffler assembly includes an outer casing having an inlet for the gas stream from the vacuum pump. Wall means are provided within the outer casing to form a passageway to circulate the gas stream adjacent the inner wall of the casing. Entrained oil and water from the gas pump are collected on the inner walls of the assembly and flow under the influence of gravity to a collection pipe at one end of the assembly. The inner wall means also forms a passageway from adjacent the bottom of the assembly to its top from which the cleaned gas passes.

Abstract: A uniflow cyclone separator for the removal of solid or liquid particles from a gas stream comprises a housing forming a flow path with a central body from which swirl-generating vanes extend outwardly. The housing is surrounded by a collection chamber and the vanes are formed with collection edges and channels which open through the housing wall into this chamber. Downstream of the swirl-generating vanes are outlet slots which are pitched substantially transverse to the cyclonic stream of the gas.

Abstract: Apparatus for separating solid particles from vapor which in one embodiment employs at least one zone defined by at least two generally vertical and at least two generally horizontal vanes and in another embodiment optionally employs at least one vane to inhibit turbulence in a lower portion of this apparatus to aid the settling of particles within a particle outlet means.This apparatus is particularly suited to at least partially separating solid particles from a mixture of vapors and solid particles which arise either when restoring the catalytic activity of solid particles that had previously been used to promote a chemical conversion or when carrying out a chemical conversion, such as for example hydrocarbon cracking or reforming.Improved methods employing such apparatus are also disclosed.

Abstract: A apparatus for decreasing fuel consumption of and noxious emissions from an internal combustion engine. Exhaust gases from the engine exhaust are passed through a static structure dual 90.degree. band pipe section to a selective sampler, wherein certain species are removed from the exhaust stream and the bulk of the gases pass through and exit the exhaust system. The removed species are recirculated back to the engine intake system to provide a reconstituted charge, and any liquids removed from the recirculatory lines are vaporized and also fed into the intake system. The sampler includes a number of pipes having louvers therein cooperating with the interior of a pipe section connected to the static structure.

Abstract: An air pre-cleaner is provided for use with an internal combustion engine. The pre-cleaner comprises a housing and vanes fixed to the top of the housing for imparting a circular motion to the air entering the housing between the vanes. This circular motion causes the heavy particles in the air to be projected away from the axis of the housing because of the centrifugal force on the particles caused by the circular motion. A tube means is positioned in the housing and a separator having a plurality of louvers is positioned in the housing between the wall of the housing and the tube. The heavy particles pass through the openings in the louvers and fall from the separator means under the influence of gravity and exit from the housing. The air with the heavy particles removed therefrom then passes through the tube and into the engine. A control mechanism is positioned in the housing between the separator and the exit for controlling the flow of air through the exit towards the separator.
