Dispensing sequences for beverage mixture dispensing systems are disclosed. A disclosed method for operating a beverage mixture dispensing system includes flowing a first solvent from a first reservoir to a mixing area of the beverage mixture dispensing system, dispensing concentrated ingredients into the mixing area to combine the first solvent from the first reservoir with the concentrated ingredients to form an intermediate mixture, flowing the intermediate mixture to a mixing chamber of the beverage mixture dispensing system, flowing a sweetening liquid from a second reservoir to the mixing chamber, without flowing the sweetening liquid through the mixing area, to combine the sweetening liquid from the second reservoir with the intermediate mixture to form a beverage, and dispensing the beverage from the mixing chamber. A disclosed device is configured to execute this method. A disclosed computer-readable medium includes instructions for a device to execute this method.

A dispensing assembly for cold beverages includes a beverage supply conduit, an opening and closing tap for closing or opening the beverage supply conduit, a beverage dispensing conduit delimiting a fluid passage, a dispensing outlet arranged at the end of the dispensing conduit, an air supply conduit delimiting an air passage. The tap is directly connected to the dispensing outlet by providing a connecting coupling which connects the air supply conduit to the beverage dispensing conduit, the beverage dispensing conduit comprising a Venturi segment between the tap and the outlet in which, by flowing through the Venturi segment, the fluid passage reduces the cross section thereof and then increases the cross section thereof as in a Venturi conduit. An air passage regulating valve is provided in said air supply conduit for regulating the width of the air passage.

A device and method for producing a bone cement paste from a monomer liquid and a cement powder, wherein the device comprises a cartridge with a cylindrical interior chamber for mixing the parent components, whereby the interior chamber of the cartridge is closed on the front side up to a delivery opening for expelling the bone cement paste from the interior chamber, a delivery plunger which is arranged in the interior chamber of the cartridge and which is supported in a linearly movable manner in the direction of the delivery opening, the cement powder, which is arranged in the interior chamber of the cartridge between the delivery opening and the delivery plunger, a monomer receptacle with an interior chamber in which a monomer liquid container containing the monomer liquid is contained, whereby in the monomer receptacle, a conveying plunger is arranged movable in the longitudinal direction of the monomer receptacle, a compressed gas connection, whereby the conveying plunger is arranged between the monomer liquid container and the compressed gas connection or the compressed gas line in the monomer receptacle.

Systems and methods for reducing the overall current draw of a fluid mixture dispensing device are disclosed. A disclosed system includes a mixing area, a set of ingredient reservoirs, and a set of electromechanical valves. The set of electromechanical valves are in a one-to-one correspondence with the set of ingredient reservoirs, and fluidly connect the set of ingredient reservoirs and the mixing area during a respective set of dispense times. The system further includes a controller programmed to actuate at least two valves from the set of electromechanical valves to dispense, to the mixing area, at least two ingredients from the ingredient reservoirs associated with the at least two valves. The controller is programmed to actuate the at least two valves in sequence with partially overlapping dispense times and without overlapping opening times.
