    摘要: An arrangement for use on a vehicle, especially truck for transporting portable bridges, with the sections of a portable bridge being adapted to be arranged one above the other on support frames, and being adapted to be received on the support frames, by means of a bridge placing apparatus. The support frames are distributed over the effective length, behind the cab of the particular truck, and secured to the frame or the like thereof. The support frames are provided as independent components, releasably securable to the vehicle frame or to a loading platform, and the support frame immediately adjacent the cab is provided with a pivot drive arrangement for moving the sections of the portable bridge in the longitudinal direction of the vehicle.

    摘要: Fluid absorptive bodies for hygienic purposes or the like are formed consisting of an absorptive layer of hydrophil fibers, and a sheath formed at least in part of hydrophil fibers bound together by solid particles of thermoplastic. The hydrophil fibers of the sheath, at least in part, extend into the absorptive layer and the concentration of thermoplastic particles in the sheath decreases steadily from the exterior surface of the sheath to the interior of the absorptive layer. For the purpose of manufacturing such absorptive bodies, a process s preferably employed in which the inner surfaces of a mold corresponding to the contours of the absorbent body are coated with a layer of hydrophil sheathing fleece fibers and solid thermoplastic binder, the mold is filled with absorptive material, and the entire filling is heated, at least to the surface, to the binding temperature of the thermoplastic binder.
