| 20120069428 | SINGLE-MODE PROPAGATION IN MICROSTRUCTURED OPTICAL FIBERS - The invention relates to an optical fiber as an optical waveguide for the single-mode operation. The present invention proposes a fiber having a microstructure, by which the propagation of modes of a higher order are selectively suppressed in the optical waveguide. At the same time, the propagation of transversal modes of a higher order is dampened more strongly than the propagation of the fundamental modes of the optical waveguide. | 03-22-2012 |
| 20090142809 | Method for Cleaving Cervimycin Monoesters - The invention relates to a method for cleaving cervimycin esters. An object of the invention to convert in a simple manner the cervimycin esters which are less active but formed in larger quantity into the highly active cervimycin K that occurs as a minor component in the preparation by fermentation, is achieved by preparing unesterified cervimycins from cervimycin esters with di- or monomethylated malonic acids, by ester cleavage effected by at least one esterolytic enzyme at temperatures of 20° C. to 75° C. and a pH of pH 5.0 to 10.0, preferably pH 6.0 to 9.0. | 06-04-2009 |
