Title: Method for automatically testing centrally controlled communication systems, especially those of private branch exchanges
IPC: H04M3/24
Filed: 1986-07-02
Abstract: In this method, the communications systems exhibit at least one switching computer having a corresponding memory section, the memory is subdivided in a function-oriented manner with respect to the accommodation of program information items and control data information and the control of function units, which are hierarchically interdependent due to their data volume, is implemented by the test sequence containing the program and control data information items. Starting with parameters represented by a certain number of control data, the basic decision element (E0) is formed, from which, by adding in each case one or more additional parameters, mutually independent first decision elements (E01...,E04) and in further sequence, if necessary, second and further decision elements (E011...,E014) and (E011...,E011X, E0131...E013Y) are formed which are selected step by step, starting from the basic decision element (E0) when the test sequence begins. The control data of each decision element E_, E01...) are compared in the nominal/actual comparison with existing data and the test sequence is sequentially run through corresponding events "termination, reference or activity". <IMAGE>

Patent EP-0238962-A3 (EP)
IPC: A61B5/055
Filed: 1987-03-16
Abstract: A two-step smoothing process produces a 
brightness map of an image. The image is multiplied, 
pixel by pixel, by the inverse of the brightness map 
to correct for image brightness variations due to the 
imaging system and not to the object being imaged. 
The first smoothing step scans a square multi-pixel 
window across the image to produce a gross brightness 
map of the image. The brightness value of the center 
pixel in the window is ascribed the sum of the values 
of all pixels in the window. In an alternate 
embodiment, the center pixel in the window is 
ascribed the brightness of the brightest pixel in the 
window. The second smoothing step scans the gross 
brightness map with a smaller square window to smooth 
blockiness in the gross brightness map for producing 
a smoothed brightness map. Smoothing ascribes a 
value to the center pixel in the window equal to the 
weighted sum of the remaining pixels in the window. 
The weight contribution of each pixel in the window 
is varied according to its distance from the pixel 
whose value is being calculated. Linear and 
non-linear weighting may be used. The original image 
is multiplied, pixel by pixel, by the inverse of the 
smoothed brightness map to produce a corrected image. 
The corrected image is normalized to return its 
values within the dynamic range of a display 
device.

IPC: H03G3/04
Filed: 1988-08-01
Abstract: Bei der Pegeleinstellung von Audiosignalen mit Hilfe von 
C-MOS-Schaltern (IC1) (Multiplexern) entstehen während des 
Einstellvorgangs Knackgeräusche, die durch kapazitive 
Verkopplungen der digitalen Ansteuersignale in den Nutzsignalpfad 
einstreuen.  
     Um diese Störgeräusche zu vermeiden, wird das Nutzsignal (Ue) dem 
Eingang eines gleichartig aufgebauten C-MOS-Schalters (IC2) 
zugeführt. Das Nutzsignal wird an diesen Eingang 
jedoch über einen Inverter (INV) gegenphasig gelegt. Die 
Ausgänge der beiden C-MOS-Schalter sind (IC1, IC2), gegebenenfalls 
über Verstärkerstufen (OP2, OP3), an je einen Eingang eines 
Differenzverstärkers (OP4) geschaltet. Am Ausgang dieses 
Differenzverstärkers entsteht ein von Knackgeräuschen freies 
Nutzsignal (Ua), da nur die Störgeräusche kompensiert werden.  
     Die Erfindung wird insbesondere in Audioverstärkern verwendet.

Patent EP-0304170-A3 (EP)
IPC: G01K11/24
Filed: 1988-07-22
Abstract: Apparatus for measuring high temperatures in a boiler (10) 
transmits (20) pulses of acoustic waves from one side wall (22) of the 
boiler to an opposite side wall (24) thereof. Acoustic noise within 
the boiler, as well as the transmitted pulses of acoustic waves, are 
received (26) at the opposite side wall (24) of the boiler. The 
received signal is digitized (56) and compared to a digitized sample 
of the pulses during a time period which is more than the maximum 
transit time for the pulses between the side walls (22, 24). A point 
of maximum correlation between the sample and the signal is taken as 
the arrival time for the pulse and is used to calculate the transit 
time of the pulse across the boiler. This transit time is used in 
turn to calculate the velocity of the pulses. The temperature can 
then be calculated as a function of the velocity, the molecular weight 
of the medium and the specific heat ratio of the medium. Each pulse 
had a modulated frequency between 500 and 3000 Hz.

Title: Procedure for the bleaching of pulp
IPC: D21C9/14
Filed: 1989-09-18
Abstract: The invention concerns a procedure for the bleaching of pulp using an oxidating bleaching chemical containing chlorine. The essential features of the invention are that the chemical used in the oxidation stage has a chlorine dioxide content of at least 50 %, that the pulp is subjected to enzyme treatment either in conjunction with or before the oxidation, and that, after the oxidation and enzyme treatment, the pulp is treated with an alkali. The use of enzymes reduces the amount of chlorophenols and other forms of organically bound chlorine in the spent bleach liquor, simultaneously lowering its chemical oxygen demand.
