A vacuum pump that evacuates an inside of a vacuum chamber and powder capturing devices disposed on an intake side of the vacuum pump are included. The powder capturing devices include a plurality of flow path forming units that form a continuous gas flow path from an intake unit located on the vacuum chamber side to an exhaust unit located on the vacuum pump side. The plurality of flow path forming units include a first flow path forming unit having a first catching unit that causes the powder sucked from the intake unit to collide and then catch the powder, and a second flow path forming unit having a second catching unit that causes the powder passing through the first flow path forming unit to collide and then catch the powder.

A gas-liquid separator includes a housing being supplied with water-containing gas, a gas-liquid separation portion being provided inside the housing and separating water from water-containing gas, a water storage portion being arranged on a bottom portion of the housing and storing water separated by the gas-liquid separation portion, and a valve mechanism enabling discharge of and stop of the discharge of water in the water storage portion via a discharge flow path communicating with the water storage portion. An inner wall of the housing has a guide surface flowing water toward the water storage portion and is provided with a regulating portion regulating staying of water in a vicinity of a flow-in port of the discharge flow path.

This device is intended to separate oil droplets from a gas stream and comprises an inlet wall (2) having at least one inlet opening in which there is disposed a propeller for accelerating and radially orienting the gas stream and at least one retaining wall (3) having at least one retaining medium disposed facing a propeller (8). Advantageously, the inlet wall (2) and the retaining wall (3) are linked by a hinge allowing the retaining wall (3) to be folded against the inlet wall from an unfolded production configuration to a folded use configuration.

A moisture trap for removing liquid from a fluid drawn from a tissue site treated with reduced pressure and systems and methods for using the same are described. The moisture trap may include a barrier adapted to be fluidly coupled to and define an indirect fluid path between a fluid reservoir and a reduced-pressure source. The barrier may have a hydrophilic surface. The moisture trap also may include a sump adapted to receive condensation from the barrier.

Turbogenerator (1) for an aircraft (2) comprising:—a turboshaft engine (3); —an electric generator (4) comprising a rotor (5) driven mechanically by the turboshaft engine (3) and a stator (6) supported by a housing (7) of the electric generator (4); characterized in that the turbogenerator (1) comprises a static separator (8) for separating an air/oil mixture coming from the turboshaft engine (3), the static separator (8) being positioned around the housing (7) of the electric generator (4).

The invention relates to an apparatus for analyzing heterogeneously catalyzed reactions comprising at least one reactor (3) through which a particulate catalyst flows and at least one reactant feed, wherein arranged downstream of each reactor (3) is a separation apparatus (17) for separating the particulate catalyst from a reaction product comprising condensable gases and arranged downstream of the separation apparatus (17) is a liquid separator (31) for separating liquid constituents from the reaction product, wherein the liquid separator (31) comprises a metallic tube (103) and a deflection body (119), wherein the metallic tube (103) is closed at its ends and the deflection body (119) is accommodated in the metallic tube (103) and the metallic tube (103) comprises a side feed (135) at a first end (105) and a gas outlet (113) at a second end (107) and the gas outlet (113) is connected to at least one sample vessel (37). The invention further relates to a process for analyzing heterogeneously catalyzed reactions in the apparatus.

A coke catching apparatus for use in hydrocarbon cracking to assist in the removal of coke and the prevention of coke build up in high coking hydrocarbon processing units. The apparatus includes a grid device for preventing large pieces of coke from entering the outlet of the process refining equipment while allowing small pieces of coke to pass through and be disposed of The coke catching apparatus can be easily disassembled to be removed from the refining process equipment and cleaned.

A fuel vapor storage canister including an integral fuel trap is provided. The fuel trap includes bifurcated chambers with the dual purpose of trapping liquid trace and attenuating noise entering the canister shell and tank line. The upper chamber includes a baffle to block and collect liquid trace, the liquid trace falling through an opening in a partition for collection in a fuel trace collector. The fuel trace collector is suitably positioned within the lower chamber, immediately beneath the opening, and includes a cavity and a venturi. The venturi creates a region of low pressure during purging, which evacuates the cavity by suction. The cavity optionally includes an activated carbon billet, which maintains the pressure level in the fuel vapor line above a predetermined minimum value and which aids in converting the liquid trace to fuel vapor as well as in further attenuating noise escaping into the tank line.
