  • Publication number: 20240083680
    Abstract: A load carrier for loading and unloading a container includes rigid load-carrier segments, each having a length and width in first and second directions, respectively, and an upper side in a third direction. In a first state, the upper sides are parallel to one another and, in the first direction, one behind the other, to form a planar loading surface. The segments are mutually connected in an articulated manner such that they are pivotable to one another about pivot axes parallel to the second direction. In the first state, a respective segment which, in the first direction, follows a respectively other segment, is pivotable, by its upper side, toward the upper side of the other segments, so that, by the segments being rolled up in spiral form, the load carrier is transferrable from the first into a second state and, by unrolling, is transferrable back into the first state.

  • Patent number: 7604092
    Abstract: In an exhaust system of a motor vehicle, a tailpipe cover is disposed on the exhaust pipe and protrudes through a cutout in the vehicle rear part with a defined gap clearance. In a hot condition, where a length of the exhaust system is increased due to thermal expansion, a greater clearance arises between the edge of the cutout and the tailpipe cover than in the cold condition. The tailpipe cover is trumpet cone shaped.

  • Publication number: 20090250831
    Abstract: The invention relates to a polyester based on a polycondensation product of terephthalic acid and/or terephthalic acid derivatives comprising bivalent alcohols. Said polyester is characterised in that (I) between 40 and less than 90 mol. % of ethylene glycol, propane-1,3-diol and/or butane-1,4-diol is combined with (II) between 60 and more than 10 mol. % alkane-1,2-diol, exclusively ethylene glycol, and the polyester has a melting point of between approximately 145 and 250° C. (in accordance with DIN EN ISO 53765). It has a comparatively low melting point, such that it can be retreated at the lower melting temperature. This prevents undesired secondary and decomposition reactions during the retreatment, and enables energy costs to be reduced. The inventive polyester is especially suitable for producing fibres or filaments by melt-spinning, and films, bottles and other moulded parts according to an injection moulding method. The fibres can be treated to form a high-quality nonwoven material.
