  • Publication number: 20030119099
    Abstract: New genes containing a DNA sequence coding for hydroxynitrile lyase, which genes can be prepared via a primer combination based on the DNA sequence of of the 5′-region of the mdl genes from Prunus serotina and from Prunus amygdalus and/or a primer 2 based on the 3′-region of the DNA sequences of one of the hydroxynitrile lyase isoenzymes from Prunus serotina or from Prunus amygdalus, subsequent amplification with a DNA polymerase using a DNA from organisms, containing genes coding for hydroxynitrile lyase, as templates and cloning, and also recombinant proteins which can be prepared in suitable host cells by heterologous expression of the DNA sequence of said HNL genes, and proteins and fusion proteins derived therefrom and use of said proteins for preparing (R)- or (S)-cyanohydrins.

  • Patent number: 6319697
    Abstract: (S)-Hydroxynitrile lyases which have an improved substrate acceptance and which are derived from the Hevea brasiliensis and Manihot esculenta (S)-hydroxynitrile lyases, wherein one or more bulky amino acid residues within the hydrophobic channel leading to the active center have been replaced with less bulky amino acid residues.

  • Patent number: 5736018
    Abstract: A device for holding components during electrode application includes two rigid plates having openings formed therein. An elastic material lines the openings in the plates and defines free spaces in the elastic material for receiving components.
    Type: Grant
    Filed: August 19, 1996
    Date of Patent: April 7, 1998

  • Patent number: 4408123
    Abstract: A fiber optical sensor device is provided for measuring a physical parameter. The sensor device contains a light source which emits a light beam into the end of a first light transmitting fiber. Light delivered from the output end of the fiber is directed to a light dispersing or selecting device such as a prism or an interference filter. This device disperses or splits the light transmitted by the first light transmitting fiber into its spectral components. The sensor device also contains a second light transmitting fiber. The input end of this second fiber receives the spectral components, whereby the components to be transmitted by the second fiber are selected dependent upon the physical parameter to be measured. The output end of the second fiber directs the selected component(s) to a light detector which measures the component intensity. The output signal of the detector is a measure of the physical parameter.

  • Patent number: 4379226
    Abstract: A light beam is transmitted by a fiber optical cable to a light modulation device such as a vibrating filament, bar or plate. This device or oscillator modulates the light intensity with a frequency which is dependent upon the physical parameter to be measured. Oscillations are sustained by a striking device. The modulated light beam is transmitted by a fiber optical cable from the measurement location to an evaluation location where the frequency of the modulated light beam is measured. The measured frequency is a function of the physical parameter.
