  • Publication number: 20160052385
    Abstract: The invention relates to an operating-fluid container (1) for a motor vehicle, comprising a container body which is assembled from two mutually complementary injection-moulded shells (2a, 2b) which consist of thermoplastic material and are welded together in an encircling manner to form a substantially closed hollow body, wherein at least one shell (2a, 2b) is at least in regions formed from thermoplastic materials having different strengths, wherein at least one part-region consists of a thermoplastic material having a fibrous filling, wherein the shell (2a, 2b) has been obtained by way of a co-injection process during injection moulding.

  • Patent number: 7665273
    Abstract: The method for generating a substantially uninterrupted connection of the peripheral wall portions of two adjacent tubular segments each provided with flanges having holes therein, of a tower, in particular for a wind energy turbine, comprises the steps of: arranging a first tubular segment (18) and a second tubular segment (20) with said flanges (26, 28) thereof facing each other and said holes (34, 36) in said flanges (26, 28) aligned with each other; connecting said tubular segments (18, 20) by prefastening screws (38) extending through said aligned holes (34, 36) in said flanges (26, 28); forming into the side (50) of the tubular segments (18, 20) opposite to the flanges (26, 28) a notch (52) of a predetermined width at least at a location of said contacting flanges (26, 28) where a gap (48) having a width greater than a minimum width exists; inserting into said notch (52) at least one insert part (60) having a width substantially equal to the width of said notch (52); and completely fastening said screws
