Patent DE-3240685-A1 (DE)
Title: Process for the preparation of minerals of different densities
Inventor: IMHOF RAINER DR
IPC: B03B5/10
Filed: 1982-11-04
Abstract: The preparation of minerals of different densities on a wet delivery settling machine was hitherto performed by means of foreign boundary layer fractions having a density between the density of the heavy minerals present in the mineral mixture and the density of the light minerals present in the mineral mixture or of the gangue. A separation of the heavy from the light minerals or the gangue is especially very difficult or practically impossible to effect by means of such foreign boundary layer fractions if the density difference between the heavy and light minerals is very small, i.e., less than about 1 g/cm<3>. This is to be attributed to the fact that mixing of the foreign boundary layer fractions with the heavy and light minerals cannot be avoided in the settling process due to the small density difference. According to the invention, however, a sharp separation of the heavy from the light minerals of different densities is achieved on a wet delivery settling machine by supplying foreign materials, whose density approximately corresponds to the density of the heavy minerals present in the minerals, to the minerals to be prepared.

Patent DE-3247711-A1 (DE)
Title: Device for increasing the dimensional accuracy (trueness) or measuring accuracy by automatic readjustment of electronic distance measuring devices on machines having at least two rotating cutting (knifing) discs (parting wheels)
Inventor: GRESSER GERMAN
IPC: B26D7/26
Filed: 1982-12-23
Abstract: In order to increase the dimensional accuracy or measuring accuracy of electronic distance measuring devices which display the distance a of, e.g., two rotating cutting discs, automatic readjustment to an arbitrarily selected reference point is undertaken. This readjustement is effected by, e.g., an operating cam with a microswitch or the like. At a defined cutting disc distance a as reference point, a highly accurate control pulse is triggered which is fed to an electronic control input of the counter and then triggers a preprogrammed circuit which sets (calibrates) the digital display to the value of the distance a. Possible measurement errors and/or inaccuracies are thereby continuously eliminated automatically.

Title: Arrangement on a retaining brake for railway shunting operations
Inventor: SCHMALL JUERGEN DIPL ING
IPC: B61K7/12
Filed: 1983-03-21
Abstract: A retaining brake (3) which is located on an incline and is activated is not to be released until it is ensured that the vehicles (2) which have been retained hitherto have been taken over by a shunting engine (4) i.e. until all the vehicles are coupled to one another and to the shunting engine. In order to determine this, the retaining brake is provided with measurement sensors which react to the forces respectively taken up by the brake. If these forces are reduced in a predetermined manner, this is an indication that the shunting engine is trying to pull away the vehicles and that the couplings are correctly engaged. The brake can then be opened and the engine can pull or push the vehicle train out of the siding. <IMAGE>

Title: Method and device for monitoring the surface of a moving material layer
Inventor: HALTER EUGEN DIPL PHYS
IPC: G01N21/89
Filed: 1984-04-06
Abstract: In this case, one or more light sources of a specific wavelength are used in a known way to illuminate a selected section of the material layer, the reflected light is recorded by a camera, and the signal thus obtained is evaluated, in order, e.g. to determine flaws. This method is improved by selecting a specific wavelength of the light source that is tuned to the surface to be monitored and the marks, patterns or flaws, by detecting the light reflected from the surface simultaneously in various wavelength regions, by deriving signals therefrom and by processing the latter in the electronic evaluating system to form a signal characteristic of the state of the surface. One wavelength region can, for example, be selected to correspond to the conditions of the contour of the moving material layer, and another wavelength region can be selected to correspond to the mark, the pattern or the flaw.
