Abstract: A defoaming apparatus is used in a reactor in which a chemical reaction, involving the formation of foam, is effected. The defoaming apparatus includes an impeller disposed at an upper portion of an interior of the reactor, and a motor for rotating the impeller about an axis thereof. The impeller has a plurality of radially outwardly-extending blades. Each of the blades is in a form of a flat plate or a curved plate. A plurality of impellers may be arranged along the axis of rotation. In this case, the impellers of the same configuration can be circumferentially disaligned from each other. The outer edge of each blade is inclined.

Abstract: An apparatus suitable in particular for degassing fluoropolymers which have been subjected to thermal degradation contains--in the direction of flow of the product--a product intake, a coolable conveyor section, a comminution apparatus, a heated conveyor section and a product discharge, the entire apparatus being designed to be gastight and advantageously being designed to be resistant to pressure surges and having a gas outlet in the area of the coolable conveyor section and/or in the area of the comminution apparatuses.

Abstract: An apparatus for the treatment of a multiphase fluid, comprising a rotatable shaft having a fluid flow path coaxial with the shaft. A fixed guide member surrounds the shaft and comprises annular plural helical channels for imparting centrifugal forces to the fluid to concentrate heavier fluid into an outer annular flow path around an inner flow path for lighter fluid. An impeller is supported on and driven by the shaft. The flow in the outer flow path is diverted, so as to divert the flow of the fluid of greater specific gravity into an annular channel member having an impeller. A stationary scoop extracts fluid from the channel member. The impeller comprises generally radially outwardly extending disks receiving fluid flowing on the inner flow path between them. Guide vanes are carried by the disks for guiding the fluid radially outwardly. A discharge chamber in the form of a volute is provided for the lighter fluid on the inner flow path issuing from between the disks.

Abstract: A method and an arrangement in a circulation lubrication system including a lubricating oil tank; pressure pipe lines for supplying oil to parts to be lubricated; return pipe lines for returning the oil from the parts to be lubricated to the oil tank. To eliminate problems caused by moisture, a blower is arranged to blow air into the oil tank, and at least one valve is positioned in the oil return pipe lines, the valve being arranged to allow the discharge of the air blown into the oil tank and the air with moisture and dirt flowing in the return pipe lines from the oil return pipe lines.

Abstract: A fluid centrifuge device for separating fluids and/or solids comprises a non-rotatable containment vessel (6) and a rotatable shroud (6A) of conical or other form within said vessel (6). The vessel (6) is located between an inlet assembly (2) including a manifold (8) which leads to the interior of a tubing housing (14) of a turbocharger and an outlet assembly (4) including two outlets (10, 10A) for respectively clean and dirty gases. The shroud (6A) is mounted on a drive shaft (20) for rotation therewithin. The shaft (20) and the shroud (6A) are driven by turbine blades (16) or by other drive.

Abstract: A rotary gas separator for use with a progressive cavity pump which includes a separation housing having an internal separation chamber with a bladed separator rotatably mounted therewithin for separating introduced fluid into a gas constituent and a liquid constituent. Coupling mechanisms are mounted on a first end of the bladed separator for connection to a rotor of a progressive cavity pump, and for permitting limited longitudinal movement and limited transverse movement between the bladed separator and the rotor to prevent bearing failure within the drive train of the pump.

Abstract: A gas separator for a submersible centrifugal pump or well has hardened cases on the components exposed to well fluid within the interior of the gas separator. The gas separator has a cylindrical sidewall with a bore. A shaft driven by a motor of the pump extends through the bore. An inducer is located in the bore for applying pressure to the fluid. In one type, a spinning guide vane imparts swirling motion for the well fluid to separate as it flows through a straight-through bore section. In another type, a tubular barrel locates in the sidewall, defining an intake chamber. The intake port in the sidewall is located above the intake port in the barrel, causing a reverse direction flow to separate gas from the liquid.

Abstract: Lubricant in exhaust fluid from a pneumatic motor is extracted by a separator. The separator comprises a housing in which a cyclonic flow of the exhaust is created to expel the lubricant in the exhaust. The exhaust is directed through a turbine within the housing wherein lubricant is deposited on blades of the turbine and then expelled against a housing wall by rotation of the turbine. After passing through the turbine blades, the exhaust flow is forced to reverse direction thereby extracting additional lubricant due to centrifugal force. After the lubricant has been extracted, the exhaust flows through a filter to remove other particles before exiting the separator.

Abstract: Gas is separated from fluent material, particularly a liquid or a cellulose fiber suspension having a consistency of about 8-18%, utilizing a closed separation apparatus having a spiral housing with a central axis, a fluent material inlet channel, a fluent material outlet, and a gas outlet. A pressure differential is maintained between the inlet channel and the spiral housing, and the pressure differential is converted to kinetic energy of the fluent material by causing the fluent material to flow through one or more spiral flow paths through the inlet channel toward the spiral housing. In the spiral housing a rotor is rotated to impart a strong centrifugal force to the fluent material to cause gas to separate and collect adjacent the central axis of the spiral housing, from which the gas is removed. The strong centrifugal force caused by the rotating rotor discharges the fluent material through the outlet. The spiral flow paths may be stationary or may rotate with the rotor in the spiral housing.

Abstract: The present invention describes a passive membrane degasser device in which solid chunks of photographic materials (15) are pumped past a hydrophobic membrane (10). Air from in between the chunks is forced through the membrane by pump pressure including a screw auger (11) and a vacuum (12) on the outer side of the membrane. The solid chunks of photographic material (15) are then transferred to a liquefier where conventional ultrasonic deaeration is performed. This device causes no sensitometric problems and permits using a continuous liquefaction system without the use of a centrifugal vacuum degasser.

Abstract: A centrifugal oil de-aerator includes a centrifuging bowl which is mounted for rotation about its axis, and radial blades mounted within the bowl at one end such that the oil to be de-aerated can be projected as a jet onto the blades to cause the bowl to rotate at high speed to generate a de-aerating centrifugal force on the oil which is thrown outwards onto the inner surface of the bowl, the bowl being open at its end remote from the blades and the inner surface of the bowl widening out towards this open end.
