Title: Contactless measurement of contours, esp. of moving objects, e.g. rolled material - projecting light gap onto object, focussing image onto CCD camera and evaluating coordinates derived from camera signals
Inventor: ISSELSTEIN FRITZ DIPL ING
IPC: G01B11/02
Filed: 1991-09-07
Abstract: The method involves projecting the light gap onto the object, e.g using a laser, and focussing its image onto a flat CCD camera arranged in a defined position w.r.t. the projector. The camera signals are processed to produce coordinate values. The positions of pixels with maximum intensity and the average intensity are stored for each image line and used to form a trigger level. Coordinates and intensity values are then determined before and after positions exceeding and falling below the trigger level. The coordinate values are then fine corrected using half pixel widths before being fed to a data processing system. USE/ADVANTAGE - Esp. for measuring contours of moving rolled material at high speed both during rolling and for end monitoring. Method is effective for complex profiles.

Title: Reducing sulphur content in flue gases from coal fired furnaces - by adding wet or dry paper waste to hard or brown coal before charging furnace
Inventor: GARTZEN JOHANNES PROF DR RER N
IPC: B01D53/50
Filed: 1992-03-12
Abstract: Method includes using calcium-contg. substances in the form of wet or dry paper waste mixed in the required amt. with the coal before this enters the furnace. The paper waste has a max. of 50% residual moisture; mixing, in the required amt., wet or dry paper waste with brown coal used for firing small furnaces and briquetting the mixt. before feeding it in; moisture content of brown coal and of paper waste to correspond; paper waste to be briquetted and fed to the furnace with hard or brown coal in the required proportion. 1000kg Of dry paper waste produces about 220kg of calcium carbonate, and supplies the heating value of about 600kg of cellulose, and so coal is saved. 1000kg Of paper waste contg. about 39% water produces about 138kg of calcium carbonate. Use of paper waste with about 38% moisture is possible with brown-coal firing, as freshly-mined brown coal has a water content of about 50%. USE/ADVANTAGE - Redn. of sulphur content in the flue gases is achieved at very low cost (other methods can be very costly). Coal is saved because the paper waste contains heat energy, and the disposal of large quantities of such waste material is done at low cost and without harmful emissions.
