A mixing apparatus may include a bowl defining at least one bowl opening for contents of the bowl to exit therefrom, and a valve assembly configured to selectively attach to the bowl at the bowl opening and including at least one base portion defining a base opening and configured to selectively receive a seal portion, the seal portion being movable between open and close positions, wherein in the open position, the base opening is unobstructed allowing contents of the bowl exit the bowl via the base opening, and in the closed position, the seal portion blocks the base opening preventing contents from exiting the bowl.

A mixing-dosage apparatus for rotary machines for packaging containers includes a mixing portion and a dosage portion. The two portions have a selective fluid connection using a flow control valve, which acts between the two portions so as to feed the dosage duct with consecutive loads of mixed food mass. Each load has a volume that is approximately equal to the volume of the mixing chamber.

Behavior of a flow of foam ejected to a gypsum slurry can be stabilized, and a relatively large amount of foam can be homogeneously or uniformly dispersed in the slurry. A mixer has a mixing area for preparing gypsum slurry, a slurry delivery section for delivering the slurry from the mixing area, and a feeding port for feeding foam to the slurry in the mixing area and/or the slurry delivery section under pressure. The slurry having the foam mixed therein is supplied to a production line for forming gypsum boards or gypsum-based boards. The feeding port is provided with a partition member dividing an ejecting region. The ejecting region is divided into a plurality of openings, which simultaneously eject the foam to the slurry.

A production apparatus includes a receiving device designed to receive a first and a second capsule containing a first and a second formulation, respectively, the receiving device being designed to be in an open position in which the first and the second capsule can be introduced into the receiving device and a closed position in which the receiving device holds the first and second capsules in position, the receiving device further being designed in such a way that when the receiving device holding the first and second capsules is moved from the open position to the closed position, the first and second capsules are connected; the apparatus further includes a mixing machine designed to receive the receiving device holding the first and second capsules, and to mix the first and second formulations contained in the first and second capsules such as to obtain the composition.

An apparatus for accommodation and dispensing of miscible materials has an accommodation vessel having a lower region in the form of a truncated cone, with a lower discharge opening in the direction of gravity, and ha a mixing mechanism shaft disposed centrally in a mixing space, which shaft has at least one mixing mechanism that revolves in the accommodation vessel. The discharge opening is provided with a displacer apparatus that projects into the interior of the lower region of the accommodation vessel. The lower end of the mixing screw or mixing spiral of the mixing mechanism projects into the approximately V-shaped channel between the lower vessel wall and the displacer apparatus.

Metastable state spore incubation mixing systems are described. An example system includes a spores container to store spores, a nutrient container to store nutrients, a water supply line, a syringe tank, a syringe pump, an adjustable valve, a heater, and a controller. In a drawing phase of the system, a controller can cause the syringe pump and the adjustable valve to draw into the syringe tank a volume of spores, nutrients, and water to form a mixture. The controller causes the heater to heat the mixture for a period of time. In a dispensing phase of the system, the controller can cause the syringe pump to expel the mixture through the adjustable valve and into a water distribution system. The controller can direct the system through a number of other phases of operation.

Provided is a water carbonation unit including: at least one water feed and at least one pressurised carbon-dioxide feed; a merging duct extending between a first, closed end and a second end, the at least one water feed and at least one carbon-dioxide feed opening into said duct at said first end; said second end opening into a mixing chamber linked to a carbonated water outlet; the carbonated water outlet configured to restrict outflow of carbonated water from the chamber to thereby maintain pressure within the chamber while carbonated water flows out of the carbonated water outlet.

A constrictor valve can be associated with a conduit in fluid communication with a mixer to control a flow of cementitious slurry discharged from the mixer through the conduit. The constrictor valve can include a constrictor housing, a webbing constriction assembly, and a drive mechanism. The webbing constriction assembly includes a pair of rotatable members rotatably mounted to the constrictor housing and a plurality of webbing straps connected to the rotatable members and wrapped around the conduit. The drive mechanism includes a drive shaft and a gear assembly configured to rotate the rotatable members in opposing winding directions in response to the drive shaft rotating in a tighten direction to wrap the webbing straps tighter around the conduit to compress it and to rotate in opposing unwinding directions in response to the drive shaft rotating in a loosen direction to loosen the grip of the webbing straps on the conduit.

Bone cement applicators and methods for application of a bone cement dough, the applicators and methods comprise a tubular cartridge with an internal space, a dispensing plunger for expelling the starting components through an opening of the cartridge opposite from the dispensing plunger, wherein the dispensing plunger is mobile in longitudinal direction in the internal space of the cartridge. The applicators and methods further comprise a hose, an application opening, a three-way valve operable from outside and arranged or arrangeable in the hose or on a side of the hose facing the cartridge, and a collecting container arranged on the three-way valve. The three-way valve is designed and arranged or arrangeable in the applicator such that it, being in a first position, provides a fluid connection between the application opening and the opening of the cartridge and closes a feed-through to the collecting container and, being in a second position, provides a fluid connection between the application opening and the collecting container and closes a passage to the opening of the cartridge.

This application discloses a slurry processing apparatus and a battery processing device. The slurry processing apparatus may include a slurry mixing assembly, a viscosity monitoring assembly, a controller, and a suction pump. The slurry mixing assembly may be configured to mix a slurry. The viscosity monitoring assembly may be configured to monitor a viscosity parameter of the slurry in the slurry mixing assembly. The controller may be separately connected to the slurry mixing assembly and the viscosity monitoring assembly, and the controller may be configured to receive the viscosity parameter and control operation of the slurry mixing assembly based on the viscosity parameter. The suction pump may have an inlet, and the inlet of the suction pump may be connected to the slurry mixing assembly through a first pipe for sucking the slurry in the slurry mixing assembly.
