Abstract: A composite with a thermoplastic matrix and fiber reinforcement is made by rotation of an exit die about a roving of continuous fiber in the presence of a thermoplastic melt. The rotation causes opposing inner and outer helical flow conditions which reduce the melt viscosity of the polymer by shear thinning while dragging and directing the polymer into the fiber roving thereby wetting and dispersing the fiber. A composite structure is formed with a polymer rich skin and a core region of unidirectionally aligned polymer and fiber. The polymeric skin is composed of helically aligned polymer chains which are coiled by the rotation around the core to compress the core region and enhance fiber wet out.

Abstract: Composite polymeric articles, which may be in layer or film form, comprise a larger portion of a polymer which is water soluble at 20.degree. C. against a smaller proportion of a polymer which is substantially water-insoluble at that temperature. For example, a layer product may have a thin layer (e.g. less than 5 microns) of insoluble polymer superimposed on a thicker layer (e.g. at least 20 microns) of soluble polymer. Both polymers are conveniently polyvinyl alcohol, which is non-toxic and useful in a number of domestic applications, e.g. as a diaper backing sheet. The insoluble portion gives water resistance but negligible mechanical strength; the soluble part gives the mechanical strength. On dissolution of the soluble portion, the insoluble portion disintegrates mechanically. Articles may be made by co-extrusion or by molding.

Abstract: An apparatus for the passivating, multistage compaction of hot iron particles supplied in the form of a packed bed from a reduction unit and for the subsequent breaking apart of the compacted iron band is described. Prior to the final compacting, the iron particles pass through a homogenizing and precompressing stage. Thus, the compacted iron has a pore volume of max. 40% and a density of at least 5.5 g/cm.sup.3. The iron compacted to a band is subsequently guided between the rollers (7,8,11) of a separating stage exposing it to bending stresses such that it breaks apart at the predetermined desired breaking points. The breaking points have a smaller density than the band regions between them. They can be produced in that in the precompression stage the feed speed is briefly decelerated compared with the feed speed in the compaction stage or in the compaction stage there is less marked compression at these points than in the intermediate regions.
