  • Patent number: 11229271
    Abstract: The present invention relates to a locking mechanism (13) comprising a first locking member (11), a second locking member (12), and a biasing member (14) exerting, during operation, a biasing force (FB) on at least the first locking member (11) or the second locking member (12) in a biasing direction (B). The locking mechanism further comprises a guiding structure (32) for mutually guiding the first and second locking members (11, 12), wherein the first locking member (11) comprises a track structure (15) and the second locking member (12) comprises a guided element (16) guided by the track structure (15). The locking mechanism (13) is moved from an un-locked to a locked condition by applying a pushing force to at least one of the first and second locking members (11, 12). The locking mechanism (13) can be moved from the locked to the un-locked condition by applying either a pushing or a pulling force to at least one of the first and second locking members (11, 12).

  • Patent number: 9901233
    Abstract: In a method of monitoring pollution of an air filter (Filt1) in a device in which an air flow (A) generated by a fan (F) engaged by a motor (M) passes the air filter (Filt1), the pollution is determined using data representative of a pressure difference (D2) over the fan (F), a pressure difference (D1) over the air filter, and a motor current (I) to the motor (M). The method comprises the steps of: estimating a flow through the air filter from data representative of the pressure difference (D2) over the fan (F), and the motor current (I) to the motor (M), estimating a filter resistance of the air filter from data representative of the flow through the air filter, and the pressure difference (D1) over the air filter, and estimating the pollution of the air filter from data representative of the filter resistance of the air filter.

  • Publication number: 20090266101
    Abstract: beverage dispensing apparatus for enclosing and cooling a keg (1) containing a beverage, comprising means for guiding the beverage from the keg (1) to a dispending tap for controlling the beverage output from the dispensing apparatus. The apparatus comprises a cooling system provided with heat transfer means (4) being in direct thermal contact with the keg (1). The cooling system is provided with an adsorbent cooling device (3) comprising a liquid chamber (5) for containing and vaporizing a liquid working substance (8), and an adsorbent chamber (6) containing an adsorbent (9) for adsorbing the vaporized working substance. The liquid chamber (5) is connected through a control valve (12) with the adsorbent chamber (6).
