[00001]$\left(n-\mathrm{present}\right)=\left(n-\mathrm{demand}\right)=\frac{\left(n-\max \right)}{\left[\left(h-\max \right)/\left(h-\mathrm{present}\right)\right]^a}$

at least when [(h-mixer)+X]≤(h-present)≤(h-max), wherein a≥(¼) and a<1, X=radius of the impeller of the flow generator+1, and all heights and measures are given in meter.

The apparatus also includes an outlet (18) for the liquid and dissolved gas downstream of the venturi. At least part of the liquid inlet, at least part of the gas inlet, at least part of the venturi and at least part of the outlet are formed in an integrally formed piece of material (42).

The controller that receives at least one sensor signal indicative of a measured profile of a particulate material within a storage tank of an agricultural system. The controller also determines whether a variation between the measured profile and a target profile is greater than a threshold value. The controller outputs a first output signal to a user interface indicative of instructions to inform an operator of a profile variation, outputs a second output signal to an agitator indicative of activation of the agitator, or a combination thereof, in response to determining that the variation between the measured profile and the target profile is greater than the threshold value.

An operable measuring attachment for a mixing appliance includes a mixing bowl defining a mixing interior, a housing having a protrusion attachable to the appliance and a plurality of containers each having an interior volume.

The operable measuring attachment also includes a magnetic coupler having a first magnetic member disposed proximate the base of each of the plurality of containers and a second magnetic member disposed proximate the top of the housing. The selective magnetic engagement of the first magnetic member of any one of the plurality of containers and the second magnetic members further defines the measuring position. A scale is disposed within the housing that is in communication with the interior volume of the container in the measuring position.

A tintometric machine includes an external frame made from rigid material, which defines an internal area. The internal area houses at least one dispenser system, which can dispense at least one fluid, such as paint or dye, into a vessel or container. The dispenser system of the tintometric machine, includes one or more dispenser mechanisms and a plurality of canisters or containers. Each of the dispenser mechanisms includes at least one pump and at least one valve assembly, and the canisters or containers are connected to one or more dispenser mechanisms. The external frame of the machine has a shell-shaped structure that can be opened to divide the machine into at least two portions. Each portion contains a part of the dispenser system. By dividing the machine into portions, an inspection area is defined between the portions, which is accessible to an operator.

Assembly of a tintometric machine and a trolley includes an external frame and a dispenser system. The dispenser system dispenses a fluid into a vessel or container, when the vessel or container is positioned in a dispensing station. The trolley includes: a supporting top, whereon the container can be positioned; rotary elements allowing the trolley to move; a gripping element, through which the user can grip the trolley and move it. The dispensing station has a housing into which the trolley can be positioned. The assembly includes a plug-socket system, wherein a first part of the system is located on the trolley and a second part is located in the dispensing station. The parts of the system can be assembled together when the trolley is placed into the housing of the dispensing station, for the purpose of conducting an electric current. The trolley includes an actuating device that can move the supporting top.

A domestic carbonation appliance. The appliance has a replaceable CO2 cylinder, and accepts a refillable bottle. The appliance has a processor for controlling the functions of the device. The appliance comprises: a chassis having a filling chamber; a fill head in the filling chamber, the fill head being attachable to a source of pressurised carbon dioxide gas; the filling chamber having a safety door and locking device; the device having a sensor for detecting a door state and transmitting door state information to the processor; and the processor being adapted to initiate a carbonation process in response to the door state information.

A particulate material sensing and agitation control system of an agricultural system having a drive system configured to operate an agitating system, and a controller having a memory and a processor. The controller is configured to receive at least one sensor signal indicative of a profile of a particulate material within the agricultural system, and output a control signal to instruct the drive system to operate the agitating system in a selected operating mode of a plurality of operating modes based on the profile of the particulate material. The agitating system is configured to interact with the particulate material in each operating mode of the plurality of operating modes, and the plurality of operating modes includes an agitation mode and a leveling mode.

A mixing system and mixing method are provided. The mixing system includes a tank assembly, a container positioned within the tank assembly, a mixer disposed within a compartment of the container, a linear motor, and a shaft having a first end secured to the mixer and an opposing second end secured to the linear motor.
