Title: Method of tapping light signals from optical waveguides
Inventor: PALMSKOG GOERAN
IPC: G02B6/28
Filed: 1993-03-29
Abstract: ABSTRACT The present invention relates to a method of tapping light signals from an evanescence field surrounding an optical waveguide clad with encapsulating material, with the aid of a light conducting probe which includes an optical fiber having a free fiber end. Tapping of the light signals is effected without removing encapsu-lating material and without breaking the optical waveguide. A minimized damping loss is achieved in the tapping operation. The invention comprises the steps of inserting the fiber end of the probe down towards the encapsulated optical waveguide, pressing the fiber end of the probe into the encapsulating material while deforming the material elastically to the extent permitted by the mechanical properties of the material; and angling the fiber end of the probe to the optical waveguide, so that a part of the light signal in the waveguide is taken up in the light conducting probe.

Abstract: PCT No. PCT/NL92/00064 Sec. 371 Date Dec. 6, 1993 Sec. 102(e) Date Dec. 6, 1993 PCT Filed Apr. 3, 1992 PCT Pub. No. WO92/17410 PCT Pub. Date Oct. 15, 1992.The invention provides a method for removing sulphur compounds from water by anaerobic reduction of the sulphur compounds to sulphide, followed by a partial oxidation of the sulphide to elementary sulphur. The anaerobic reduction is carried out at elevated temperature, either continuously at a temperature of 45 DEG -70 DEG  C., or periodically at a temperature of 55 DEG -100 DEG  C. If the reduction is carried out periodically, a single rise in temperature for a few hours to several days over a period of 3-6 months can suffice. The method is particularly applicable to the removal of sulphate, sulphite and thiosulphate.

Title: Method and device in the cooling of the circulating material in a fluidized-bed boiler
Inventor: RAIKO MARKKU
IPC: F23J15/02
Filed: 1992-09-09
Abstract: ABSTRACT OF THE DISCLOSURE      The invention concerns a method and a device in the cooling of the circulating material in a fluidized-bed boiler.  In the method the fuel is introduced into the circulating-powder combustion chamber of the fluidized-bed boiler into the lower part of the circulating-powder combustion chamber and an inert circulating material, which contains a proportion of unburned powdered fuel, is circulated from the top part of the circulating-powder combustion chamber to the lower part of the circulating-powder combustion chamber.  The flue gases are passed in the method from the powder separator along the duct into the exhaust-gas boiler, through whose heat exchanger thermal energy of the flue gases is transferred further to other useful use.  In the method, part of the cooled flue gases are recirculated along the duct into the circulating material and, by means of the cooled flue gases, the capacity of cooling of the fluidized-bed furnace is regulated by affecting the temperature of the circulating material.

Title: Image scanner measuring the motion of reader and light source on a test chart
Inventor: IMAGAWA TAKASHI
IPC: H04N1/10
Filed: 1994-04-19
Abstract: A scanner is so arranged that a quantity of light reaching a CCD sensor can be kept constant with a change in reading position.  In cases where a light source and a reading optical unit are driven independent of each other, variations in feed amount inevitably occur.  To deal with it, a test chart of a specified length is first read to measure amounts of movement of the light source and the reading optical unit. Then, the reading optical unit is moved by a predetermined amount.  The light source is moved to effect a correction based on the amount of movement initially measured.  Then, a one-line reading process is carried out to scan an image on a document.
