  • Patent number: 7762180
    Abstract: An apparatus for preparing a beverage fit for consumption with a fine-bubble froth layer, in particular cappuccino. The invention provides a beverage unit, which dispenses under pressure a beverage to be processed to a beverage processing path, through which, in use, the beverage flows to obtain the beverage with the fine-bubble froth layer. The beverage processing path successively includes a nozzle and a buffer reservoir, the nozzle being positioned relative to the buffer reservoir such that, in use, it generates a liquid jet squirting into the buffer reservoir to obtain the beverage with the fine-bubble froth layer. The buffer reservoir is provided with an outlet path for discharging the beverage from the buffer reservoir, the liquid flow path, upstream of the nozzle, further including an additive holder which, in use, can be filled with a product to be dissolved in the beverage, such as concentrated milk or milk powder.

  • Publication number: 20090071344
    Abstract: An apparatus for preparing a beverage fit for consumption with a fine-bubble froth layer, such as coffee or cappuccino, provided with a beverage unit for dispensing a beverage under pressure, at least one nozzle to which the beverage is fed under pressure to generate a jet of the beverage, a buffer reservoir for collecting the jet of the beverage so that, in use, a liquid level of the beverage is created in the buffer reservoir into which the jet squirts to obtain the fine-bubble froth layer and an outlet path for discharging the beverage with the fine-bubble froth layer from the buffer reservoir, wherein the outlet path is provided with at least one siphon which comes into action for discharging the beverage from the buffer reservoir via the siphon when the liquid level in the siphon exceeds a predetermined height.

  • Patent number: 6073910
    Abstract: A coupling for connecting a first pipe part and a second pipe part comprises a first coupling part and a second coupling part, a shut-off valve arranged in the first coupling part, and locking structure. The locking structure can move with respect to one another between an unlocked position and a locked position, in the manner of a bayonet coupling. An actuator for actuating the shut-off valve is arranged in the second coupling part. The locking structure and the actuator are designed in such a manner that the shut-off valve can only be opened by means of the actuator when the locking structure is in the locked position, and in that the coupling can only be uncoupled when the shut-off valve is in the closed position. The actuator and the locking structure can be actuated separately.
