Abstract: An insulating pipe part of thermoplastic material comprises two opposite sections and one third section disposed at an angle with respect to the former sections, the wall portion of said sections being provided with a continuous wall cutting slit. The pipe part may comprise thicker parts of a polyurethan foam. For forming an insulated branch pipe joint, said insulating pipe part is pushed over a branch pipe and subsequently plastic sleeves with beveled front ends are heatshrunk on to said sections, thereby closing said slit in a moisture tight manner. In order to obtain a reliable moisture tight closing, the sleeves are provided with beveled front ends so that the lower sleeve ends overlap each other.

Abstract: An electrochemical specific-binding assay of a ligand wherein one of the components is redox-modified by having incorporated into its molecular structure a redox centre, and which includes the step of determining the extent to which an electrochemical characteristic of the components is perturbed by complex formation and/or by controlled external influences. Redox centres are molecules, atoms, groups, ions, radicals etc capable of undergoing reduction and oxidation. A preferred example is ferrocene or its derivatives. The electrochemical apparatus will typically contain a working electrode, which is preferably solid. Components may advantageously be immobilised onto such a solid working electrode. When controlled external influences are employed, these may comprise displacement of non-immobilised electroactive components relative to the working electrode. The method is particularly applicable to the assay of antigens, haptens and antibodies. The use of redox centres avoids radioactive labels and provides a simple, rapid, sensitive and specific assay method.

Abstract: The glycosides of resorufin derivatives have the general formulae Ia and Ib <IMAGE> in which R<1> is hydrogen, R<2>, R<3> and R<5>, which can be identical or different, are hydrogen, halogen or a lower alkyl group, R<4> and R<6>, which can be identical or different, are hydrogen, halogen, a cyano, lower alkyl, lower alkoxy, carboxyl, lower alkoxycarbonyl, carboxy-lower alkyl, lower alkoxycarbonyl-lower alkyl or an optionally mono- or disubstituted carboxamide group or the group  -COO-(CH2CH2O)n-R<7> in which R<7> is hydrogen or a lower alkyl group and n is an integer from 1 to 4, where R<6> can additionally be a sulphonyl or nitro group, and Y is a nitrogen or the group NO. These compounds are particularly suitable as chromogenic and fluorogenic substrates for determining the activity of corresponding glycosidases or oligosaccharide-cleaving enzymes. The glycosides are obtained by reacting resorufin derivatives with a mono- or oligosaccharide or a 1-halogeno derivative thereof, whose hydroxyl groups are substituted by customary protective groups. This initially results in per-O-substituted glycosides, which can be converted into the claimed compounds by elimination of the protective groups. The glycosides are used as chromogenic and fluorogenic substrates in diagnostic agents for detecting glycosidases or oligosaccharide-cleaving enzymes. The resorufin derivatives employed as starting materials in the preparation of the compounds are also claimed.

Abstract: A method of producing a flat polymeric yarn is disclosed which includes the steps of melt spinning a polymer to form a plurality of running filaments, combining the filaments to form a running bundle of filaments, and then guiding the running bundle into contact with a ribbon of fluid so as to apply a controlled quantity of the fluid to the bundle. The fluid coated bundle is guided over a plurality of serially arranged curved braking surfaces, and it is then withdrawn by means of a draw roll so as to draw the running bundle to an extent which exceeds its plastic limit. The application of the fluid to the bundle in accordance with the present invention results in a hydrodynamic friction, rather than a sliding contact friction, between the bundle and braking surfaces, and produces yarn of very uniform quality while also avoiding wear of the braking surfaces.
