Patent WO-0194905-A1 (WO)
Inventor: GLINGENER CHRISTOPH
IPC: G01M11/00
Filed: 2001-05-22
Abstract: The invention relates to a measuring method that allows to measure non-linearities of an optical fiber (OF) unilaterally, that is at the beginning or at the end of the optical fiber (OF). To this end, an optical test signal (ots) is launched into the optical fiber (OF), the test signal power (PS) of which is modified. A first entry threshold (SBS1) of the stimulated Brillouin scattering is detected on the basis of the modified power (Pros) of the reflected optical signal (ros). In a second step, at least one modulated optical pump signal (ops) is launched into the optical fiber (OF) in addition to the optical test signal (ots). A second entry threshold (SBS2) of the stimulated Brillouin scattering is detected on the basis of the modified power (PS) of the optical test signal (ots). The non-linearity coefficient ( gamma ) of the optical fiber (OF) is determined by evaluating the at least first and second entry thresholds (SBS1, SBS2), the test and pump signal parameters and the fiber parameters.

Title: Tyre rasp - with stamped out teeth
Inventor: ZEIDLER WILLI
IPC: B23D71/02
Filed: 1972-05-24
Abstract: The sheet metal rasp for the removal of the tread from worn out motor car tyres is stamped out from steel strip. The tooth fronts and backs have identical radii. The teeth are generated without any scrap accruing by parting slits at the blade edges during the stamping out of which the teeth are simultaneously arched sideways and their back twisted. The number of teeth per unit area is controlled by the length of the feed stops of the blades into the machine. The method permits the generation of slim pointed teeth configurations and also permits the provision of a greater number of teeth per unit area than hitherto.
