An exemplary compounding system and method can include a transfer set that includes a manifold for assisting in transferring a plurality of ingredients from supply container(s) to a final container. The manifold can include a first channel in fluid communication with at least one primary ingredient, and a second channel in fluid communication with a plurality of secondary ingredients. The first channel and second channel can be in fluid isolation from each other such that the at least one primary ingredient does not mix with the plurality of secondary ingredients within the manifold. The transfer set can include a plurality of inlet lines in fluid communication with the manifold and two outlet lines configured for connection to two separate pumps and eventually being in fluid communication with the final container.

A rotary machine for acting on a process fluid includes an impeller, a shaft, a drive, a seal and a flush casing. The impeller acts on the process fluid and is mounted on the shaft. The drive is connected to the shaft and rotates the shaft and the impeller about an axial direction. The seal has a sealing element sealing the shaft during rotation of the shaft. The flush casing receives a flushing fluid for flushing the sealing element, and delimits an annular flush chamber extending about the sealing element. The flush casing includes a bushing surrounding the sealing element and delimits a radial leakage gap arranged between the sealing element and the bushing. The bushing delimits an axial leakage gap between the impeller and the bushing, and the width of the axial leakage gap in the axial direction is adjustable.

A flow-through cavitation device having an elongated housing with an inlet and an outlet. An inner annular body and an outer annular body are concentrically and nestingly disposed in the elongated housing. The outer annular body is fixed relative to the housing and the inner annular body is rotatable about a longitudinal axis of the housing. Each annular body has a plurality of channels that pass therethrough. Rotation of the inner body relative to the outer body provides for selective alignment or misalignment of the plurality of channels to control fluid flow from the inlet to the outlet. The device may have a plurality of pairs of inner and outer annular bodies as described.

A nozzle for dispensing a beverage includes a nozzle head having a base liquid inlet configured to receive a base liquid and a flavoring inlet configured to receive a flavoring. The nozzle further includes a diffuser assembly that is in fluid communication with the base liquid inlet and which includes a diffuser plate having a plurality of peripheral openings through which the base liquid flows. The nozzle further includes a receptacle that is in fluid communication with the diffuser assembly and the flavoring inlet. The receptacle of the nozzle includes an inner wall, and the peripheral openings of the diffuser assembly are arranged so as to direct flow of the base liquid along the inner wall of the receptacle. The receptacle further includes an outlet through which the flavoring and the base liquid are dispensed.

An apparatus for mixing a liquid and a substance, including a housing with a liquid inlet and a substance inlet to a mixing chamber, an outlet for a mixture of liquid and substance, and a flow restrictor arranged in the housing, between the liquid inlet and the mixing chamber. The flow restrictor is controllable to switch between a first position providing a first through flow area configured to create a Venturi effect such that a flow of the liquid draws the substance into the mixing chamber, and a second position providing a second through flow area that is larger than the first through flow area to thereby decrease a pressure drop caused by the flow restrictor.

Attrition mills and propeller shaft assemblies therefor are described having features for enhanced installation and maintenance. Some embodiments include propellers having enhanced material processing characteristics.

Dosing and mixing exhaust gas includes directing exhaust gas towards a periphery of a mixing tube that is configured to direct the exhaust gas to flow around and through the mixing tube to effectively mix and dose exhaust gas within a relatively small area. Some mixing tubes include a slotted region and a non-slotted region. Some mixing tubes include a louvered region and a non-louvered region. Some mixing tubes are offset within a mixing region of a housing.

A storage and mixing system for pasty two-component polymethyl methacrylate bone cements comprises a tubular cartridge having a cylindrical inner chamber, a dispensing plunger that is axially displaceable in the inner chamber of the cartridge, a partition disposed axially in the tubular cartridge, and a cartridge head which closes one end of the tubular cartridge. The cartridge head has a slot-shaped opening, wherein the partition protrudes from the inner chamber of the cartridge through the slot-shaped opening of the cartridge head, wherein the partition divides the cylindrical inner chamber of the cartridge bounded by the dispensing plunger and the cartridge head into two cavities that are spatially separated from one another. A first pasty cement component is present in the first cavity and a second pasty cement component is present in the separate second cavity, wherein the partition is removable through the slot-shaped opening of the cartridge head so that the two separate cavities are connected to one another after the partition is removed.

A flow distribution system for distributing and dividing the flows of at least two separate fluids, the distribution system comprising: a three-dimensional nested structure of at least two fluid transporting fractals comprising at least a first fluid transporting fractal and a second fluid transporting fractal, each fluid transporting fractal having a respective fluid inlet which bifurcates to a plurality of fluid outlets, each fluid transporting fractal being configured to facilitate a flow therethrough independent from a flow in the other fluid transporting fractal, each fluid transporting fractal extending along and about a central axis between fluid inlet and a plurality of fluid outlets; wherein each fluid transporting fractals comprises of a series of recursive bifurcation units assembled in a selected number of stages, each bifurcation unit comprising a Y-shaped bifurcated element which is fluidly connected to two successive bifurcation units, each successive bifurcation unit being rotated relative to the central axis by an angle of between 60 and 120 degrees relative to the previous stage; each fluid transporting fractal is intertwined with the other fluid transporting fractal; each fluid transporting fractal is positioned offset from the other fluid transporting fractal about the central axis and are arranged such that each fluid outlet from one of the fluid transporting fractals is located adjoining a fluid outlet of the other fluid transporting fractal, and each fluid transporting fractal is centered about a flow axis which is laterally inclined from greater than 0 to 20 degrees from the central axis and longitudinally inclined from greater than 0 to 20 degrees from the central axis.
