IPC: F23G7/06
Filed: 1989-10-16
Abstract: Combustible impurities in oxygen-containing offgases are burnt according to a method and by an apparatus of the type in which at least some of the heat of combustion is recovered by a regenerative heat exchange in two identical heat exchange zones (10,11) containing a solid heat exchange material and separated by a combustion chamber (15). The air or gas to be purified flows through both of the heat exchange zones and by means of valves (1,2,3,4) the direction of flow is changed periodically so that the two zones are alternately heated and cooled in periods of 0.1-60 minutes. The risk of discharge of unburnt combustible contaminants to the atmosphere is minimized by dividing the purified gas stream in the first 1-50% of each period into two part streams of which one is discharged directly from the combution chamber (15) to a recipient (22) whereas the other is passed through the heat exchange zone (10 or 11) being heated and from there recycled through a line (25 or 24) controlled by a valve (7 or 6) and combined with unpurified gas being passed to the heat exchange zone (11 or 10) being cooled.

Title: Data compression
Inventor: CLARK ALAN D
IPC: H03M7/30
Filed: 1989-12-06
Abstract: ABSTRACT     A method of processing data for transmission from a transmitter T to a receiver R both  of  which  are switchable between a compression mode in which the data stream is encoded or decoded with a data  compression algorithm and a transparent mode in which the data stream is transmitted or received unencoded , comprising reading an input data stream at the transmitter T, encoding at least  part  of the input data stream with  the  data compression algorithm to form a compressed data stream, monitoring   the   efficiency of compression   of   the compressed data stream and controlling the switching of the mode of the transmitter T and receiver R so that the input data stream is transmitted efficiently.     In the transparent mode both the receiver and the transmitter   check   independently  the  efficiency  of compression and switch to the compression mode if the transparent mode is determined to be inefficient.  In the compression  mode  the  transmitter  T  determines  the efficiency of compression and transmits a control code to the  receiver  R,   switching  both  the  receiver  and transmitter to the transparent mode if the compression mode is determined to be inefficient.

Inventor: KREMAR DJURO
IPC: B65H43/08
Filed: 1990-05-31
Abstract: In a web reeling machine such as the reeling portion of a paper machine the successful introduction of a fresh reel bar to maintain the continuity of the reeling operation is dependent upon turn-up of the web onto the rotating reel bar followed by build-up of a roll on the reel.  The end of a bifurcated fiber optic cable is positioned adjacent the jaw clamps that retain the stationary end bearings of the reel bar so as to provide an indication of the occurrence of successful turn-up by  detecting  a persevering  change  in the clamp/bearing relationship due to roll growth.  The other end of the bifurcated cable is connected to an light emitter and a light detector.  The light emitter generates  a  light signal along the bifurcated fiber optic cable towards a light guide path in a jaw clamp so that the light signal passes through the light guide path.  When the jaw clamp moves, the light guide path moves and the jaw clamp reflects the light signal back toward the bifurcated fiber optic cable which transmits the reflected signal to a light detector which detects the change in reel bar location due to roll growth.  The system can tolerate motion inconsistencies caused by reel bar bounce, due to a rough turn-up of the web.
