Patent DE-3107246-A1 (DE)
Title: Measuring cell for detecting the corrosion of metals
IPC: G01N17/02
Filed: 1981-02-26
Abstract: This invention employs a special measuring apparatus consisting of parts which are in some cases of completely new design. In order to meet the high requirements imposed on such an apparatus, suitable devices were incorporated for adjusting the electrolyte liquid to desired temperatures, monitoring the pH and adjusting it by adding acid/base and for feeding the liquid past the electrodes without using mechanically moving parts. Gas flow through the electrolyte produces the required circulation. The electrolyte is heated by a heating liquid using the countercurrent method. An as interference-free measuring situation as possible was created in the measuring cell as a result of newly discovered arrangements and material properties in order to thereby obtain optimum results on the processes occurring in the course of the corrosion. A high uniformity of the currents to be measured was achieved by conically grinding the glass frit between working electrode and plate counterelectrode. The first results were correspondingly informative.

Patent DE-3204047-A1 (DE)
Title: Ignition monitoring device
Inventor: BRUEGGEMANN REINHOLD DIPL ING
IPC: F23Q9/00
Filed: 1982-02-06
Abstract: The invention relates to an ignition monitoring device, particularly for infrared radiating burners, in which condensation of water vapour can impair the operation of an ignition electrode and of an ionisation sensor electrode, these electrodes being mounted in lateral reflector walls. To prevent such faults, the ignition and ionisation sensor electrodes are arranged in chambers which have cross sections delimited by sharp edges and open to the reflector walls. The ignition electrode ends in the region of the reflector wall, while the ionisation sensor electrode actually projects from the chamber. Because of the sharp-edged delimitation of the chambers, the flame gases flowing past arrive in these only with a delay which is sufficient for the flame gases to give up a portion of their moisture to the surrounding parts, i.e. to the reflector wall and the floor wall. This ensures that condensation within the chambers is prevented, so that the electrodes can fulfil their function undisturbed.

Title: Method and arrangement for allocating the grey scale values of an image to other grey scale values
Inventor: SCHLINDWEIN MICHAEL DR RER NAT
IPC: G06V10/28
Filed: 1982-04-21
Abstract: To emphasise the required body organ or for suppressing its environment in the automatic analysis of X-ray images, for example from mass examinations, the electronically recorded image is treated in such a manner that only the grey scale range of the desired organ is transmitted in the image and the remaining grey scale values are suppressed. Due to various influences, the grey scale values of the desired organ are not always within the same grey scale value range in different images so that the use of a fixed grey scale value window presents problems. According to the invention, the grey scale values of the image to be examined are allocated to the grey scale values of a standard image in such a manner that the difference between the aggregate frequencies of the successive grey scale values forms a minimum and the pair of grey scale values in which the minimum occurs in each case is stored. As a result, an optimal grey scale value window selected with respect to the standard image can also be applied to the image to be examined after the transformation of the grey scale values of the latter. <IMAGE>
