Title: New cobalt complexes of monoazo dyestuffs
Inventor: ESSBACH GUENTHER
IPC: C09B45/20
Filed: 1963-10-29
Abstract: The invention comprises the mixtures of two symmetrical and one asymmetrical cobalt complexes obtained by treating an equimolar mixture of the dyes of formulae <FORM:0993908/C4-C5/1> wherein X is a hydrogen or chlorine atom or a nitro group and Y is a hydrogen or chlorine atom with a cobalt-yielding agent.  The dyes colour polyamide fibres, particularly wool, in yellow shades. In an example a mixture of the dyes 4-nitro-2-aminophenol --> acetoacetic acid - p - sulphamyl - anilide and 4 - nitro-2 - aminophenol--> acetoacetic acid o-chloroanilide is treated in aqueous alkaline solution with cobalt sulphate.

Abstract: 1466412 Blow-moulding OWENS-ILLINOIS Inc 2 Oct 1974 [3 Oct 1973] 42723/74 Heading B5A Articles of non-uniform cross-section are produced by locating a tubular preform of substantially uniform cross-section and substantially uniform wall thickness between blow-mould halves, the cavity walls of which, when closed, are spaced apart a distance less than the cross-sectional dimension of the preform, closing the blow-mould to contact and flatten the preform and thermally stabilize the contact portion while retaining its substantially uniform wall thickness and blow-moulding the preform to the final shape of the article. The preform may itself be blow-moulded from an extruded or injection-moulded parison. As shown in Fig. 1, parison 20 is pinched shut at 21 by mould halves 22 and blow-moulded into circular-section preform 30 by blow pipe 25 which also co-operates with neck moulds 24 to form neck 26, tail flash 28 being removed by puller blocks 27. The preform 30 is then transferred to between final-blow-mould halves 40, Fig. 6, which close on and flatten the preform to a shape nearer that of the final article, the mould walls 41 being chilled to set the preform wall to its final configuration on contact. The flattened preform is then finally blow-moulded by air supplied through pipe (35, Fig. 3, not shown). In the embodiment of Figs. )-15 (not shown), a preform (60) having a crosssection comprising two semicircular portions (70, 71) but of different diameters is formed in blow-mould halves (61, 62) and finally blowmoulded to a concave-convex article (80) in co-operating female and male blow-mould parts (75, 76 respectively). The final article may be a serving dish, tray, boat hull section, bicycle seat &c.
