A plastic beer keg includes an outer container and an inner liner. A removable lid is secured over an opening to the container to enclose the liner. In use, the lid can be removed and ice placed in the container directly on the liner, ice flows into gaps between the liner and the container to provide rapid cooling of the content of the liner.

An imaging tube assembly (11) for a computed tomography (CT) system (10) includes an insert (60) that has a vacuum chamber (72). An anode (58) resides within the vacuum chamber (72) and rotates on a shaft (66) via one or more bearing (70). In one embodiment, a seal (52) resides between the insert (60) and the shaft (66). The seal (52) prevents the passage of a gas (80) into the vacuum chamber (72). In another embodiment, a pressure transition chamber (104) is coupled to an insert (60″) and a shaft (66″). The pressure transition chamber (104) has an associated middle fluid pressure that is between an internal fluid pressure of the vacuum chamber (104) and an external fluid pressure of said insert (60″).

The invention relates to a power module comprising a substrate (2), whose surfaces are provided with at least one electrically conductive layer (4, 6), at least one active semiconductor chip (8), which is electrically connected to an electrically conductive layer (6), a film (12) consisting of an electrically conductive material, which is in close contact with the surfaces of the semiconductor chips (8) of the electrically conductive layer (6) and the substrate (2) and is provided with planar printed conductors (16). According to the invention: the module is equipped with a second film (18), which is in close contact with the surfaces of the printed conductors (16) and the first film (12); a passive semiconductor chip (22) is applied to said second film (18), above the active semiconductor chip (8) and is electrically connected to the planar printed conductor (16) lying below by means of a window (14) that is configured in the second film (18); the module is equipped with a third film (24), which is in close contact with the surfaces of the passive semiconductor chip (22) and the second film (18) and said third film (24) is provided with a planar printed conductor (28), which is conductively connected to the conductive layer (6) lying below the active semiconductor chip (8). The invention thus provides a compact power module that can comprise complex topologies.

A motor-driven supercharger is provided with a stator assembly inserted and attached to a bearing housing, and a seal plate closely attached to a compressor side of the stator assembly and comparting between a compressor housing and a motor stator (24). The stator assembly has the motor stator and an outer sleeve having an inner peripheral surface closely attached to an outer peripheral surface of the motor stator and supporting the motor stator in such a manner as to constrain a rotation of the motor stator, wherein the motor stator and the outer sleeve form an integral part so as to construct the stator assembly, and the outer sleeve constructs a liquid tight water cooling jacket between the outer sleeve and the bearing housing. The outer sleeve and the seal plate are fastened together in an axial direction between the bearing housing and the compressor housing.

Pyrolysis methods and apparatuses that allow effective heat removal, for example when necessary to achieve a desired throughput or process a desired type of biomass, are disclosed. According to representative methods, the use of a quench medium (e.g., water), either as a primary or a secondary type of heat removal, allows greater control of process temperatures, particularly in the reheater where char, as a solid byproduct of pyrolysis, is combusted. Quench medium may be distributed to one or more locations within the reheater vessel, such as above and / or within a dense phase bed of fluidized particles of a solid heat carrier (e.g., sand) to better control heat removal.

Provided is a machine body capable of preventing thermal decomposition of a liquid reducing agent in a reducing agent injector. The machine body includes an exhaust gas treatment device that reduces nitrogen oxides in exhaust gas of an engine provided within a machine room, and a reducing agent supplier that supplies the liquid reducing agent to the exhaust gas treatment device. The exhaust gas treatment device includes a reducing agent injector that injects the liquid reducing agent supplied from the reducing agent supplier, and a cooling fan that is installed in the vicinity of the reducing agent injector so as to face the reducing agent injector. The cooling fan performs cooling by blowing cooling wind of external air, which is taken in from the outside of the engine room, against the reducing agent injector and its upstream side.

A turbine assembly includes a basically hollow aerofoil. A wall segment may be arranged at a side of the aerofoil. An insertion aperture in the wall segment provides access to the aerofoil and an impingement tube may be inserted via the insertion aperture into the aerofoil to be located within the aerofoil and extend at least in a span wise direction of the aerofoil. A protrusion section of the impingement tube may extend in a direction basically perpendicular to the span wise direction over an edge of the insertion aperture. The protrusion section may be overlapped by at least a part of the wall segment. Adjacent to the protrusion section, an overlap section of the impingement tube is arranged to abut the edge of the insertion aperture. The protrusion section and the overlap section may be formed integrally with each other in one piece.
