Abstract: A filter device having a sonotrode connected to a filtration assembly. The filtration assembly has a filter body having a fluid passage. The filter body has a filter across the fluid passage. The filter assembly has a resonant frequency and the sonotrode is adapted to vibrate the filter assembly at or near the resonant frequency.

Abstract: A dispensing device for free-flowing or pourable products, in particular in a refrigeration device. Said dispensing device has a feed pipe for a pourable product, comprising an exit opening and a shut-off flap that is situated at the exit opening, and an outlet for the free-flowing product, said outlet being attached to the flap and displaceable with the latter.

Abstract: A dry powder inhaler incorporates a cyclone chamber (4) comprising at least one air inlet (6) and an outlet (10) wherein the configuration of the air inlet (6) and the shape of the chamber (4) is such that in use a reverse flow cyclone is set up in the chamber (4). The chamber (4) further comprises flow disrupter means, e.g. the upper surface (14) of a protrusion (12) from the base, disposed so as in use to restrict air flowing from the base of the chamber (4) in an axial direction.

Abstract: A refrigeration appliance with a water tank having an interior with an inlet connection and an outlet connection connected to a water dispenser, the water tank being divided by at least a first fin disposed in the tank interior and dividing the interior into at least two sections through which the contents of the tank flow from the inlet connection to the outlet connection, with the at least two sections merging into one another at a free edge of the fin, with the at least one fin being formed with a through-opening formed a predetermined distance from the free edge and connecting the at least two sections, the cross-sectional dimension of the through-opening being smaller than the cross-sectional dimension of the at least two sections.
