  • Apparatus for producing a nonwoven web
    Patent number: 6908292
    Abstract: In the production of a spunbond web by aerodynamically stretching thermoplastic filaments from a spinneret, the stretching nozzle is formed by two nozzle-forming units each of which has a temperature control device, especially a heater, to minimize deformation at the stretching nozzle defining wall. The result is a reduction in the tolerance of the basis weight of the spunbond web.
    Type: Grant
    Filed: November 14, 2002
    Date of Patent: June 21, 2005
    Assignee: Reifenhauser GmbH & Co. Maschinenfabrik
    Inventors: Hans Georg Geus, Hans Jürgen Hofemeister, Falk Rösner, Detlef Frey, Karsten Sievers, Udo Schomer

  • Thermostable (1,3-1,4)-.beta.-glucanase
    Patent number: 5470725
    Abstract: Novel hybrid thermostable (1,3-1,4)-.beta.-glucanases, their use in food manufacturing and feed manufacturing, DNA fragments encoding such glucanases, organisms expressing the DNA fragments and a method for producing the thermostable (1,3-1,4)-.beta.-glucanases. Hybrid fusion genes encoding Bacillus (1,3-1,4)-.beta.-glucanases were constructed, the gene products of which are more thermostable than any (1,3-1,4)-.beta.-glucanase known until now. The hybrid genes were constructed by reciprocal exchanges of the amino-terminal and carboxy-terminal parts of the .beta.-glucanase encoding genes from Bacillus amyloliquefaciens and Bacillus macerans. The resulting thermostable (1,3-1,4)-.beta.-glucanases retain a significant enzymatic activity at temperatures exceeding 65.degree. C. and at pH values below 5.0.
