  • Patent number: 8342233
    Abstract: A device for an air handling system in which the cooling beam has a pressure chamber (2), from which the volume flow of the supply air (L1) out to the room is regulated with a regulating strip (6) that is mounted on the surfaces (9) in the pressure chamber and where the flow of the supply air (L1), in the mixing chamber (4), provides an optimal flow pattern of the recirculating air (L2) from the room and where the combined flow of supply air (L1) and recirculating air (L2) acquire well defined flow profiles independent from the volume flow (L1).
    Type: Grant
    Filed: August 20, 2010
    Date of Patent: January 1, 2013
    Assignee: Flakt Woods AB

  • Patent number: 7421953
    Abstract: A device for an overhead conveyor system of the type where a plurality of carriages (7) by contracting a rotating drive shaft (5) are propellable along a rail (2). The device comprises an operating arm (28) arranged in connection with a first carriage (7b) and adapted to actuate, by turning about an axis of rotation (26), a power transmission element (24) to disconnect the carriage from contact with the drive shaft, and an angled supporting surface (20) arranged in connection with a second carriage (7a). One end of the operating arm (28) is further adapted, when said carriages (7a, 7b) are moved towards each other, to contact said angled supporting surface (20) and be moved along the same, so that the operating arm (28) thus performs a turning motion and disconnects said first carriage (7b). According to the invention, the drive of the carriage will thus be interrupted as soon as its operating arm is contacted with the supporting surface of an anteriorly situated carriage.
