Abstract: A pair of small diameter optical fibres (14, 12) are arranged in a side-by-side configuration, the first fiber (14) doped with a material which will lase at the signal frequency, and the second fiber (12) providing a pumping source. The signal to be amplified propagates through the first fiber (14) to stimulate emission of coherent light from the lasing material, resulting in amplification of the signal. The refractive index of the first and second fibers (14, 12) are selected such that the signal in the first fiber (14) is well guided, while the pumping light in the second fiber (12) is unguided, yielding low losses in the first fiber (14) but high transfer of the pumping light from the second fiber (12) to the first fiber (14).

Title: Method and apparatus for detecting and counteracting a deformation of the stock discharge gap in a headbox of a paper machine
Inventor: STENBERG ERIK GUNNAR
IPC: D21F1/02
Filed: 1984-05-11
Granted: 1988-09-15
Abstract: The invention relates to a method and an apparatus for detecting and counteracting a deformation of the stock discharge gap (6) in a paper machine headbox, which is caused by thermal expansion due to the temperature of the stock and/orthe pressure of the stock. This is achieved by ultrasonic transducers (7;9,10; 20-22) located close to the slice opening (6) which obtain measurement results relating to the distance between the roof member (1) and the apron beam member (2) of the headbox. At least two such transducers, one (20) preferably located close to a side wall (23) of the discharge gap (6) and the other (21) preferably located midway between the side walls (23, 24), give information about a possible difference between the measurement results caused by the deformation. This difference serves as a guide for adjusting the temperature of the apron beam member (2) and/or the roof member (1), in such a way that the deformation is reduced in magnitude or entirely eliminated.
