A polymer production method whereby: a flow reactor comprising a flow path wherein a plurality of liquids can be mixed is used; and a monomer is anionically polymerized in the presence of an initiator. The flow reactor comprises a mixer for mixing two liquids, said mixer comprising either a joint member having a double pipe therein or a static mixer member.

A beverage dispensing system is disclosed that includes a container assembly configured to store two liquids (e.g., liquor and a mixer) that is couplable to a head assembly. The head assembly includes one or more pumps configured to draw the different liquids from the assembly, to mix variable ratios of the two liquids together, and to dispense the drink. In some configurations, the drink may be dispensed from the beverage dispenser into a glass or directly to the mouth of an individual.

Exemplary modular gas delivery assemblies may include a plurality of modular gas blocks coupled together. Each gas block may include an upper portion and a lower portion. A first end of the upper portion may extend beyond a first end of the lower portion and a second end of the lower portion may extend beyond a second end of the upper portion. A first fluid channel may include a first fluid port, a second fluid port, and a third fluid port. The block body may define a second fluid channel that extends transversely to the first fluid channel. A first modular gas block may be coupled with a second modular gas block and a third modular gas block such that the first fluid channels of each of the first, second, and third modular gas blocks are fluidly coupled with one another.

According to an aspect of this disclosure, there is provided a fluid processing apparatus including: a housing with a space formed therein; a fluid receiving part removably coupled to the housing and receiving a fluid therein; and a conveying part accommodated in the space of the housing and coupled to the fluid receiving part to be in fluid communication therewith, wherein the conveying part includes: a pump member coupled to the fluid receiving part and providing a conveying force to the fluid; and a mixing nozzle which is in communication with the pump member, and into which the fluid flows after having passed through the pump member.

A method for controlling fluid ratio accuracy during a dual flow injection with a powered injection system is described. The method includes predicting a first capacitance volume of a first syringe comprising a first medical fluid and a second capacitance volume of a second syringe comprising a second medical fluid with a first capacitance correction factor and a second capacitance correction factor, respectively, selecting a ratio of the first medical fluid and the second medical fluid to be administered to a patient in the dual flow injection, determining a relative acceleration ratio of a first piston of the first syringe and a second piston of a second syringe based on the predicted first capacitance volume and the predicted second capacitance volume, wherein the relative acceleration ratio is selected to maintain the selected ratio of the first medical fluid and the second medical fluid during the dual flow injection, and injecting a mixture of a first medical fluid and a second medical fluid having the selected ratio with the powered injection system.

A method as well as a liquid mixing system for providing a liquid mixture of water with at least one additive. The liquid mixing system comprises a first water reservoir, a first additive reservoir, a mixing unit, a conveying device and a line network. At least one first measurement value of the flow of the first additive conveyed to a mixing device is determined by an additive flowmeter. The total stream of the liquid mixture conveyed by the conveying device is measured by a liquid mixture flowmeter. The determined measurement values are transmitted to a control device, and from there passed on to a data storage device where they are stored.

Shape Dependent alphabets are error prone and quite imposing on their reader. Proposing “Shapeless”—an alphabet based on the entropic state of a mixture—offering easy, redundant reading. Applications include marking packages for shipping and industrial handling, signing items to hinder fraud, offering alternative communication channels, and analyzing video streams for changes of interest.

Systems and methods of custom condiment dispensing include a reservoir of base condiment and a plurality of flavoring reservoirs. A first pump is pneumatically connected to the reservoir of base condiment. The second pump is pneumatically connected to at least one flavoring reservoir of the plurality of flavoring reservoirs. A nozzle is fluidly connected to the reservoir of base condiment and fluidly connected to the plurality of flavoring reservoirs. The nozzle is configured to simultaneously dispense the base condiment and at least one flavoring therethrough. A controller receives the user selections of the base condiment and the at least one flavoring and operates the first pump and the second pump to dispense base condiment and at least one flavoring.

A polymer production method whereby: a flow reactor comprising a flow path wherein a plurality of liquids can be mixed is used; and a monomer is anionically polymerized in the presence of an initiator. The flow reactor comprises a mixer for mixing two liquids, said mixer comprising either a joint member having a double pipe therein or a static mixer member.

A mixing valve is described for a dispensing device for dispensing a cooled beverage mixed with a gas, comprising: a first inlet which can be fluidically connected to a first source of gas and can be supplied with the gas; a second inlet which can be connected to a second source of the beverage without gas and can be supplied with the beverage not mixed with the gas; an outlet which can be connected to a first dispensing mouth for dispensing the beverage mixed with the gas; the dispensing mouth is available in a closed or open configuration to prevent or allow dispensing of the beverage mixed with said gas; a chamber interposed between the first and the second inlet on one side and the outlet on the other side and adapted to allow mixing of the gas and non-mixed beverage, thus forming the beverage mixed with the gas; and regulation means, configured to allow, when the first dispensing mouth is arranged in the open configuration, the passage, respectively, of a first flow value of gas between the first inlet and the outlet and a second flow value of non-mixed beverage between the second inlet and the outlet.
