Abstract: The present disclosure provides details of an invention comprising an amplification system for the detection of target nucleic acids, most particularly target nucleic acid sequences, in an isothermal setting wherein all of the reagents necessary to conduct the amplification are present and the reactions are self-sustaining and continuous. Featured is a selective enzymatic digestion of a RNA/DNA duplex, formed by hybridization of a DNA primer with target nucleic acid, thus freeing the DNA strand for further hybridization followed by primer extension to provide a DNA duplex that can serve as a template for production of a plurality of transcripts that can be recycled and/or detected as such for deduced presence of target nucleic acid sequence. <IMAGE>
Patent NL-88775-C (NL)
IPC: D01F2/06
Abstract: In the production of filaments from viscose by extruding the viscose into a primary bath containing sodium sulphate, zinc sulphate and sulphuric acid, in proportions to prevent complete regeneration of the viscose, and then stretching the filaments while passing them through a secondary dilute acid bath maintained at a temperature above 60 DEG  C. and containing less acid and salts than the primary bath, the formation of zinc sulphide deposits is inhibited by adding a persulphate to at least one of the baths.  The persulphate may be that of sodium, potassium or ammonium and it may be used in either bath or in both. Anion-active compounds may also be added to the secondary bath, specified compounds including soap, sulphonated alcohols, sulphonated hydroxy benzenes having an alkyl substituent of 8 or more carbon atoms, sodium b -oleylethane sulphonate, sodium b -oleylamidoethane sulphonate, sodium alkyl-aryl sulphonates and long-chain alcohol sulphates.  The acid and salts for the secondary bath may be those carried over from the primary bath. The primary bath may contain magnesium sulphate.  Specifications 467,500, 652,594, 661,940 and 683,646 are referred to.

Abstract: 2.1. The object of the invention is to facilitate an improvement, as compared with the previous apparatus and the previous process for the production of mineral wool mats, with respect to the mat formation process on the drums of the accumulating conveyors arranged at the lower end of a chute. 2.2. The apparatus for continuous production of mineral wool mats features several fiberisation units (1, 2, 3, 4) which communicate with a chute (9) for the formation of a mat (14). The fibers are deposited under the influence of suction pressure onto the curved surface of the accumulating conveyor (10, 11). According to the invention, at least one of the drum-shaped accumulating conveyors (10) is designed to pivot around an axis (23) essentially arranged perpendicular to the flow direction (22) of the mineral wool in such a way and to the extent that a discharge gap (21) can be adjusted to a width corresponding to the thickness of the mat (14) to be formed. 2.3.

Abstract: The invention provides a process for producing gamma-lactones useful for incorporation in flavourings and fragrances, wherein a micro-organism which is acceptable for making food grade products and which does not metabolize gamma-lactones, is cultured aerobically in a culture medium containing as the substrate a hydroxy fatty acid having an even number 4 of carbon atoms between the carboxyl group and the carbon atom carrying the hydroxy group. The preferred micro-organism is a Saccharomyces cerevisiae, Debaromyces hansenii or Candida boidinii species. The gamma-hydroxy-alkanoic acid reaction product of the process is lactonized either in the fermentation broth or after separation therefrom. Especially suitable are 12-hydroxy fatty acids such as ricinoleic acid.   The hydroxy fatty acid may be added either pure or as the mixture obtained by hydrolysis of an ester thereof. Enzymatic hydrolysis of such ester may be done in situ in the fermentation broth.
