A medicament preparation system includes a disposable cartridge with a flow path. Various sensors may be placed on the cartridge to measure qualities of the fluid flowing through the flow path. The sensors are placed in precise locations using various approaches that make manufacturing of the cartridge efficient and repeatable. A drain line that is susceptible to fouling may be preattached and various approaches are used to remove or reduce the fouling. An elastomeric contact can also be present in the medical preparation system and used in a conductivity measurement subsystem.

A fuel injection system (4) for an internal combustion engine has a low-pressure pump for delivering fuel from a fuel tank. The fuel is fed upstream of an injector (11) of the fuel injection system (4) to a mixing device (14). The mixing device (14) has a mixer housing (18) with a fuel connection (15) for receiving fuel and with at least one coolant connection (17; 28; 33) for receiving a coolant. For the purpose of bringing about efficient mixing of the fuel and the coolant, before a collision of a fuel jet (40) of the fuel and a coolant jet (41) of the coolant, the two fluid jets (40, 41) are formed to be at least partially aligned in the same direction.

The present disclosure includes mixing apparatuses comprising a first conduit defining an inlet channel, a second conduit defining an outlet channel, and an injection assembly that is disposed between the first and second conduits. The injection assembly can comprise two or more mixers, each having a reducer conduit that defines a mixing channel and an expander conduit that defines an expanding channel. The injection assembly can also comprise a first injection conduit configured to inject fluid into the mixing channel. At least one of the mixers can comprise a shut-off valve movable from an open position to a closed position in which the shut-off valve prevents fluid from flowing from the mixer to the second conduit. Closing the shut-off valve can increase the fluid flow rate in at least one other of the mixing channels.

An apparatus is provided for dispensing a cosmetic composition, including: a cartridge holder configured to hold at least one cartridge that stores a cosmetic composition, the cartridge holder being configured to move the cartridge to a predetermined location; a container receiving area configured to hold a output container beneath the predetermined location; circuitry configured to determine the cosmetic composition in the cartridge holder, control the cartridge holder to move the cartridge holder to the predetermined location based on the determination, and control the cartridge to dispense the cosmetic composition into the output container; and a mixer configured to hold the output container and subject the output container to a predetermined movement to cause contents of the output container to mix together.

The production method of hot milk with or without froth, with a Venturi effect emulsifying device suitable for sending, into a mixing chamber, a flow of steam so as to aspirate, by Venturi effect, milk and air or only milk, comprises a production cycle of hot milk with froth and a production cycle of hot milk without froth being carried out by supplying an equal flow of steam of equal duration into a mixing chamber having equal volume, equal conformation and equal inlet section of the milk but a different outflow section of the milk.

A flow control device comprises a laminate structure of an electroactive material layer and a non-actuatable layer. An array of orifices is formed in one of the layers wherein the orifices are open in one of the rest state and actuated state and the orifices are closed in the other of the rest state and actuated state. Actuation of the electroactive material layer causes orifices to open and close so that flow control function may be implemented.

Disclosed is a mixing device including a chamber defining a circulation zone, the circulation zone including at least one base liquid and a mixing fluid, the mixing fluid being less paramagnetic than the base liquid, the mixing fluid including and/or consisting of at least one first fluid, the mixing device including at least one magnetic element which generates a magnetic field in the circulation zone so that the mixing fluid flows into the base liquid, the chamber including at least one first injection point of the first fluid into the circulation zone, the first injection point opening into the base liquid.

A device for producing nanoparticles includes: a first connector comprising a first supply tube fitting member, a second supply tube fitting member, and a first discharge tube fitting member; a first tube having one side connected to the first supply tube fitting member; a second tube having one side connected to the second supply tube fitting member; a first conduit having one side connected to the first discharge tube fitting member; a first supply connected to another side of the first tube to supply a first material to the first conduit; and a second supply connected to another side of the second tube to supply a second material to the first conduit.

A bubble generator includes an ejector including a flow passage, a water supplier that supplies water into the flow passage, an air supplier that supplies air into the flow passage, a cleaner supplier that supplies a cleaner into the flow passage, and a bubble discharger that discharges bubbles generated by mixing the water, the air, and the cleaner; a water supply device that supplies water to the flow passage via the water supplier, and a cleaner supply device that supplies the cleaner to the flow passage via the cleaner supplier. The cleaner supplier is formed on a lower surface of the flow passage.

A liquid ejection device for a vehicle washing facility comprises a storage volume, a first supply line coupled upstream to the storage volume for supplying a first liquid, a supply unit coupled upstream to the storage volume for supplying a second liquid, and a removal line coupled downstream to the storage volume for discharging the liquid to be ejected, with a shut-off device for shutting off liquid flow through the removal line. The storage volume is sealed so that an increase in an internal gas pressure occurs in the storage volume when liquid is introduced. The device further comprises a detection unit for detecting the supplied volume of the second liquid into the storage volume and the internal gas pressure in the storage volume, and a control unit controls the supply of the second liquid based on the detected supplied volume of the second liquid and the internal gas pressure so that a predetermined mixing ratio of the first and second liquid is achieved in the storage volume.
