Patent EP-0421657-A2 (EP)
Inventor: REDFORD GARY
IPC: G01M11/00
Filed: 1990-09-25
Abstract: Optical signal attenuation due to bends in an optical fiber (12) is measured by bending a segment of the optical fiber (12) into the shape of interest, measuring the attenuation in that segment, propagating the bent region along the length of the optical fiber (12), and repeating the measurement. The attenuation as a function of the position of the bent segment along the length of the optical fiber (12) is thereby measured. The approach is of particular interest in determining peel point bending loses along the length of the optical fiber (12) to identify areas of signal transmission.

Abstract: A method for combined cycle electrical power generation comprises utilising a coal hydrogenator 2 and a reactor 1 for producing from a methane-rich gas a hot crude hydrogen-containing gas which is fed directly (apart from an optional quenching stage) to the coal hydrogenator. The coal hydrogenator produces gaseous and liquid products which are combusted to drive a gas turbine 5 which drives an electrical generator 6. The hydrogenator also produces char which is combusted in a boiler 10 to form steam to drive a steam turbine 11 which, in turn, drives another electrical generator 12. 
     Such direct use of the hot crude gas avoids having to pre-heat hydrogen-containing feed to the hydrogenator.

Abstract: A table having a plurality of holding portions for holding recording heads to be tested is arranged to be pivotal between a printing position and a changing position, so that the recording head located at the changing position can be changed during estimation of the recording head located at the printing position. An estimation pattern in which dots are arranged so as not to contact each other is printed on a recording medium by the recording head held by the holding portion located at the printing position. The printed estimation pattern is read by an image pick-up device, and character amounts in units of dots are extracted from image data obtained by the image pick-up device. Pattern estimated values are calculated according to the dot character amounts, and whether or not the recording head is normal is judged on the basis of the calculated pattern estimated values. 
     Another estimation pattern is printed on the recording medium. The printed pattern is read by the image pick-up device, and an edge image is extracted from density image data obtained by the image pick-up device. After enlargement/reduction processing is performed for the edge image, an edge image is extracted again. Shape character values in units of areas separated by edge lines of the edge image are obtained, and the pattern and a stain if any are discriminated based on the shape character values, thereby detecting a stain state. 
     A one-dimensional average density in the line direction of the pattern is obtained from the density image data, and a line width is obtained based on the average density. A stain is detected on the basis of the line width. 
     Thus, whether or not a recording head is normal is estimated.
