Abstract: 1,012,375. Moulding hollow fibre-resin bodies. KOPPERS CO. Inc. June 17, 1964 [June 17, 1963], No. 25154/64. Heading B5A. Hollow fibre-resin articles are made by first constructing a mandrel having a circular crosssection, the circumference of which, at any point along its length, is twice the peripheral length of the cross-section of a mould, which is to be later used to form the hollow article, at a corresponding point along its length. Fibre-resin strip material is then applied to the mandrel and the shaped preform thus produced subsequently removed, applied to the mould, and then shaped and cured, or hardened, by conventional techniques. The resin may be partially cured or hardened prior to removal from the mandrel. In the embodiment shown, a mandrel 22 is constructed, as stated above, to correspond to a car body mould 20, and glass fibres 26, impregnated with resin at 32, are wound thereon from a longitudinally reciprocated machine 28. The material thus applied is then partially cured, cut horizontally into two preforms 36 (not shown), removed from the mandrel, and the preforms applied to moulds 20 and shaped and cured by a conventional bag moulding process (see Figs. 7 and 8, not shown). If required, the preform may be formed by removing the material whole from the mandrel and then folding it longitudinally within itself.

Title: Process for the manufacture of anthraquinone dyestuffs
IPC: C09B1/20
Filed: 1960-07-19
Abstract: Water-insoluble anthraquinone dyes are made by heating a tetrahalogenated 1 : 5- or 1 : 8-diamino-anthraquinon or a mixture thereof with concentrated sulphuric acid or oleum in the presence of boric acid or boron trioxide. When oleum is used at least one mol. of boric acid or boron trioxide must be used per mol. of sulphur trioxide.  The process may also be conducted by halogenating the diaminoanthraquinone in concentrated sulphuric acid and then carrying out the heating step without isolating the halogenated diaminoanthraquinone. The products contain halogen and it is believed that during the heating step predominantly a -halogen atoms are exchanged for hydroxyl groups or sulphated hydroxyl groups.  The product may be fractionally precipitated from the reaction mixture by successive dilutions with water to obtain dyes containing lower or higher contents of halogen. Examples are given.  The dyes dye polyester fibres from aqueous dispersion in blue shades. Specification 787,379 and German Specification 110,769 are referred to.
