  • Patent number: 9033756
    Abstract: The present invention relates to a method of and a vertical pumping device (1) for internally distributing Hg in a fluorescent tube body (3). The bottom (7) of the fluorescent tube body (3) is closed. The device (1) arranges, in a first position, a first solid body (9?) comprising a predetermined first amount of bound Hg. The device (1) arranges, in a second position, a second solid body (9?) comprising a predetermined second amount of bound Hg. A first release (E1) of the first amount of Hg is achieved in the fluorescent tube body (3) by gasification with heat and under pressure for purification of contaminant particles in the fluorescent tube body. A second release (E2) of the second amount of Hg is achieved in the fluorescent tube body (3) by gasification attained for the occluded mercury vapour of the fluorescent tube body (3).

  • Publication number: 20120248962
    Abstract: The present invention relates to a compact fluorescent tube (1) designed for cold spaces, which compact fluorescent tube (1) comprises at least one fluorescent tube body (13) formed into a U-shape and comprising two fluorescent tube body legs (17), which latter have an interspace (19) between them and each comprise a base part (9), enclosing a cathode chamber (11), and a top part (15) facing away from the said base parts (9), which base parts are fixed to a socket part (3), comprising current feeder members (5) for electrical contact with the cathode chambers (11). An insulating member (21, 47, 55) is arranged on the top part (15) of the compact fluorescent tube and is configured with at least one insulating cavity (23, 49), which, during operation of the compact fluorescent tube (1), is heated by the self-produced heat of the compact fluorescent tube (1).

  • Patent number: 8061981
    Abstract: In a blade intended to be exposed to a gas flow at high speed during operation of a flow machine comprising the blade, the blade includes a front end designed to face towards the incoming gas flow and a rear end. The front end is provided with a concave area that is such that during operation a stagnation point for the incoming gas flow arises at a distance in front of an outer blade surface that defines the concave area and such that the outer blade surface is thereby at least partially protected from the incoming gas flow.

  • Patent number: 7798778
    Abstract: A wheel for a rotating flow machine, comprising a rotor (1) on which a plurality of blades (2) are arranged projecting radially from the rotor (1), with each blade (2) having a root (3) attached to the rotor (1) and a blade top (4). In addition, the wheel comprises a ring (5) arranged concentrically in relation to the rotor (1) outside the blade tops (4) in such a way that the ring (5) and the blades (2) overlap each other when the ring and the blades are viewed in a radial direction, which ring (5) is arranged to be caused to rotate by the blades (2) when the rotor (1) rotates. The extent (9) of the blades (2) in a radial direction and the internal dimension (10) of the ring (5) are matched to each other in such a way that there is a clearance (?) between each blade top (4) and the ring (5) in radial direction when the rotor (1) is not rotating.
