Abstract: In order to transport large size windmill towers, the invention suggests a steel tower (1) for a windmill, comprising a number of cylindrical or tapered tower sections (2), at least the wider sections (2) of which being subdivided into two or more elongated shell segments (3), which combine into a complete tower section (2) by means of vertical flanges (6) tightened together, e.g., by bolts (10), said shells being also provided with upper and lower horizontal flanges (4), respectively, to allow interconnection of tower sections (2) one on top of the other.

Abstract: A system for treatment of particle bearing liquid is provided. The system comprises control means and an homogeniser valve, said control means being operable to cause a gap defined by the homogeniser valve to be periodically temporarily increased thereby to allow any accumulated particulate matter to pass through the valve, the valve then continuing to provide an homogenisation of subsequently flowing liquid when the valve returns to its normal mode of operation.

Abstract: A cover (101) for being located on an infusion device, which cover (101) comprises an upper plate element (103) with an upper face (104) and a lower face (105) oriented towards the upper face of the infusion device, wherein the lower face (105) of the plate element (103) comprises attachment means (106), which means cooperate with elements on the infusion device. Hereby the risk of bacteria and soil collected thereon penetrating into the construction, is reduced considerably, and likewise the cover yields a smoother surface with an ensuing minimisation of the risk of the infusion device being torn off.

Abstract: Continous glass filaments, and fibres obtained by comminuting the filaments and microfibres obtained by flame attenuation of the filaments, are formed of a substantially colourless aluminosilicate glass containing 25 to 52% SiO2, 20 to 35% AL2O3 and 0 to 1.5% FeO and having good biosolubility.

Abstract: A method and a system is provided for producing a needle of plastic, as well as a needle of plastic, in particular a needle for medical purposes. The method produces a needle having at least the outer diameter of one end being less than 0.50 mm using a moulding system having an assembly comprising a feed system and a mould cavity. The method includes introducing a melt of plastic into the feed system, increasing the melt pressure gradually during melt passage through the feed system, passing the melt into the mould cavity whereby the melt substantially fills the mould cavity, cooling the melt in the mould cavity whereby the melt solidifies to a needle, and removing the needle from the mould cavity.

Abstract: A method and a system is provided for producing a needle of plastic, as well as the needle of plastic which includes a needle for medical purposes. The method for producing the needle includes introducing a melt of plastic into a feed system, increasing the melt pressure gradually during melt passage through the feed system, passing the melt into the mould cavity, whereby the melt substantially fills the mould cavity, cooling the melt into the mould cavity whereby the melt solidifies to a needle, and removing the needle from the mould cavity. Increasing the pressure through the feed system provides for meeting specific pressure demands at the entrance of the mould cavity, thereby moulding thin and elongated articles.

Abstract: A method and system for determining the dimensional volume of a package by moving the package on a conveyor belt system over a horizontally disposed strip containing machine-readable indicia indicating units of incremental length along said strip starting from a zero point and by a vertically disposed strip containing machine-readable indicia indicating units of incremental length along said strip starting from a zero point, with a horizontally disposed reader above the horizontally disposed strip to read the uncovered indicia on the horizontally disposed strip and a vertically disposed reader able to read the uncovered indicia on the vertically disposed strip with a computer to determine the lowest uncovered incremental length measurement of the indicia on tile horizontally disposed strip, such measurement being tile width of tile package and the lowest uncovered incremental length measurement of tile indicia on tile vertically disposed strip, such measurement being tile height of tile package, and a device
