Abstract: A power recovery separator for processing huge volumes of high temperature pressurized dirty gas en route to a high temperature gas expander. The separator has a single housing sub-divided into overhead, inlet and underflow chambers by a pair of flanged and dished heads of erosion and heat resistant material having a higher coefficient of expansion than the housing material. A multiplicity of inertial separators are supported in parallel between the dished heads and secured to only one thereof. At least portions of the head flanges bear radially against the interior of the housing sidewalls and their rim edges are welded to the housing and, in consequence, expansion of the head serves, in part, to augment the bulge and, in part, to place the high strength housing wall in hoop tension without subjecting the welding to rupture stresses.

Abstract: A particle-containing air stream is passed downwardly through an orifice into a housing and toward an upwardly facing target area in the housing while directing a flow of liquid upwardly through said target area and thence outwardly in generally horizontal paths extending in opposite directions along said area and along extensions of said area, whereby particles from the air stream are entrained in the liquid flows in said opposite directions. Particle-laden liquid is discharged through bottom outlets of the chamber at the outer ends of said horizontal liquid paths, while passing divided streams with remaining particles upwardly from the respective horizontal liquid paths and into respective chambers where particles are separated by a cyclonic action from the air streams before they discharge from the chambers.

Abstract: A bubble rake for removing the remaining steam from liquid water that is returning to heat-exchange surfaces after an initial separation from steam. The bubble rake is a channel-forming member having a cross section generally in the shape of an upside-down U. The bubble rake is disposed in a fluid-flow path so that the channel opens down and in the direction of the path. A stall zone formed by a rake traps steam in the channel, and the channel is positioned longitudinally at an angle with the horizontal so that the trapped steam migrates to its high end, where an opening allows the trapped steam to join the steam previously separated from the water.

Abstract: A side outlet cyclone separator tube having an improved vortex generating device and an air cleaner incorporating the separator tube are disclosed. The tube includes a conduit member which defines a generally axial passageway for the discharge of contaminants from contaminant laden air. A second conduit member is disposed within the first conduit member and defines an outlet passageway for the discharge of clean air through an opening in the side wall of the first conduit member. The improved vortex generating device includes an elongated hub about which are spaced a plurality of generally helical deflecting vanes. A trailing end of the elongated hub has a curved surface which directs contaminants radially toward the inner surface of the first conduit member.

Abstract: A combination exhaust-gas cleaner and muffler for particular use in an exhaust system of an automotive engine incorporating in the exhaust system a catalytic converter using a granular catalyst which is responsible for emission of dust particles of oxides of base or noble metal, comprising at least one centrifugal separator for separating the dust particles from the exhaust gases by imparting a centrifugal force to the stream of the exhaust gases, a dust collection chamber communicating with the centrifugal separator for collecting therein the dust particles separated from the exhaust gases and at least one silencer chamber also in communication with the centrifugal separator for dampening out noises which are borne by the exhaust gases. For the purpose of growing up the ultrafine dust into coarse particles, a particle growing chamber stuffed with a flocculent metallic material such as steel wool may be located upstream of the centrifugal separator.

Abstract: A glandless centrifugal pump and wet electric motor unit for use in fossil-fired power plants has a cover which is sealingly connected with one end of the main portion of the motor housing and contains one or more cyclone separators for solid impurities. Liquid to be relieved of solid impurities is fed into the cover by way of a tangential inlet and such liquid passes through a coarse-mesh sieve which intercepts large solid impurities before the thus filtered liquid reaches the cyclone separator or separators. The separator or separators admit cleaned liquid into a channel provided which is provided therefor in the housing of the motor. The smaller solid impurities accumulate in a chamber which can be cleaned by way of a sealable opening while the cover remains attached to the main portion of the housing.

Abstract: A muffler particulate trap for an internal combustion engine comprising a housing adapted to be connected to the exhaust stream of the engine through an inlet port, said housing also having an outlet port for communication with the atmosphere, between the inlet port and outlet port, in serial arrangement in the housing, there is at least one chamber containing refractory alumina of requisite high porosity and high surface area and, in communication with said chamber(s), at least one cyclone separator that vents the exhaust stream through said housing outlet into the atmosphere.

Abstract: An improvement in a regenerator which incorporates an external plenum on the exterior of the regenerator apparatus for receiving and collecting the flue gases separated from regenerated catalyst by a plurality of cyclone separators or other separating apparatus is disclosed. The external plenum communicates by means of stand pipes through the wall of the regenerator. This supports the cyclone separators or other separating means mechanically and avoids certain thermal stresses which would otherwise occur in the plenum if it were placed on the interior of the regeneration chamber.
