A multiple submergence depth diffused air system includes: a vessel having a non-flat bottom floor and fluid; a single blower or compressor that provides a single mass flow and a single pressure discharge of air; a plurality of air distribution lines that extend from the single blower or compressor into the fluid, in which outlets of the plurality of air distribution lines have grids with air diffuser units for distributing air; and orifice plates associated with each air distribution line. At least some of the air distribution lines extend to different depths within the fluid and at least one of the air distribution lines extend into the fluid formed in the non-flat bottom floor of the vessel. The orifice plates can also be sized and configured to produce a unique pressure head for each air distribution line at a designated mass flow of air to the respective air distribution line.

A fluidic oscillator includes at least one inlet port (57) in communication with at least two outlets (61) via a nozzle region and two outlet conduits (58, 62), the two outlet conduits being separated from each other by a splitter region. Each outlet conduit includes a resonance chamber (60) in fluid communication with the conduit. The resonance chambers contribute to controlling the oscillation of the device. The fluidic oscillator is operatable in an acoustic switching mode.

An assembly for selectively aerating a beverage. The assembly includes a body, a diverter movable between first, second, and third positions, and an aerator in fluid communication with the diverter, the aerator including a central outlet and aeration outlets. When the diverter is in the first position, the diverter is positioned such that the beverage flows through the body and the central outlet while bypassing the aeration outlets. When the diverter is in the second position, the diverter is positioned such that the beverage flows through the aeration outlets while bypassing the central outlet. When the diverter is in the third position, the diverter is positioned such that the beverage flows through the body, a first portion of the beverage flows through the central outlet while bypassing the aeration outlets, and a second portion of the beverage flows through the aeration outlets while bypassing the central outlet.

A sparkling water making device for carbonating water in a water container with pressurized gas including a body having a container compartment for the water container having an opening through which the water container is placed inside the container compartment; a carbonation head in connection with the container compartment for connecting the water container to the sparkling water making device and for carbonating water in the water container; and a sliding door in connection with the opening arranged to slide between an open position, in which the container compartment is accessible from outside the container compartment through the opening, and a closed position, in which the opening is closed with the sliding door to provide a closed container compartment.

A carbonation machine includes a carbonation head to sealingly couple to a bottle filled with liquid to be carbonated; a piping to introduce and compress carbon dioxide into a space within the bottle above a top surface of the liquid to a predetermined pressure level when the bottle is coupled to the carbonation head; a stirrer to stir the liquid to enhance absorption of carbon dioxide in the liquid when the bottle is coupled to the carbonation head; and a manually operated valve mechanism configured to be moved to any position between a closed position to an open position for user-controlled release of pressure within the space.

Various examples are provided related to smart hydrostations or water fountains. In one example, a smart hydrostation includes a water system that can filter water for dispensing via an aeration nozzle located in a dispensing chamber; an electrical system that can monitor user access to the hydrostation and control dispensing of the filtered water; and one or more display panel that can display content transmitted to the hydrostation. A cloud-based system can provide the content for display. In another example, a system can include smart hydrostations at different locations in communication with a cloud-based system including a control center that can remotely control operations of the hydrostations and a monitoring system that can monitor operational conditions of each hydrostation.

A receiving apparatus for receiving a bottle for a carbonation machine; the receiving apparatus has a securing apparatus for securing the bottle, the securing apparatus has a locking element, the locking element has a guiding means; when the receiving apparatus is moved from the bottle receiving state into the fitting state, the locking element is guided by the guiding means such that the bottle is secured by means of the locking element; the locking element is configured to be pivoted about a locking element axis; the locking element in the bottle receiving state is arranged in a radially outer position; when the receiving apparatus is moved from the bottle receiving state into the fitting state, the locking element is pivoted about the locking element axis from the radially outer position into a radially inner position, and the radially inner position is configured to secure the bottle.
