Patent DE-3506411-A1 (DE)
Title: Interactive electronic display with high resolution and a common electrode
Inventor: MILOSIU JOHANN-MARIUS DIPL ING
IPC: G11C7/00
Filed: 1985-02-23
Abstract: Consideration is given to the design of interactive electronic displays with high resolution and with a common electrode. The display according to the invention is conceived as the basic module for the design of relatively large display surfaces, and offers a series of advantages as against other solutions. The luminous material used is an electroluminescent layer (e.g. vapour deposited ZnS:Mn-layer), which has a transparent electrode, covering the entire area, on the side directed outwards and, on the other side, metal surfaces having the size and shape of the "luminous points"; the last metal surfaces are partly transparent, since they are correspondingly thin in configuration, so that a portion of the emitted light also impinges inwards, specifically onto a light sensor of an associated control circuit which by means of optical feedback permits the automatic retention of a respective "luminous point" in the luminous state. The design avoids additional connecting elements between the lower metal surfaces and the control unit, and this permits simple and therefore cost effective production, for example by the use of vapour deposition technology. In a further embodiment, low-temperature solder is used for the connections between the luminous part and control units. The current consumption of the luminescent layer is extremely low, (virtually a capacitor), and this represents a significant advantage in application.

Patent DE-3526003-A1 (DE)
Title: Scrubbing water treatment for the simultaneous SO2 and NOx gas purification with an integrated stage for the reduction of iron III to iron II in the scrubbing water circulation by reducing the pH and circulating of sulphur dioxide
Inventor: HOELTER HEINZ DIPL ING
IPC: B01D53/68
Filed: 1985-07-20
Abstract: "Scrubbing water treatment for the simultaneous removal of SO2 and NOx from flue gases with integrated conversion from iron III to iron II". In the main application P 3524046.6, it is described that when the pH is reduced by addition of acid to pH below 3, ironIII is reduced to ironII, as a result of which the addition of additional reducing agents for the conversion of ironIII to ironII is no longer necessary or can be substantially reduced. To optimize the overall reduction process, according to the invention it is proposed that the solid (3), produced in the precipitation vessel (2) by calcium hydroxide (1a) from a part-stream (1) of the scrubbing liquid circulation, is acidified in a reaction vessel (4) by sulphuric acid (5) to a pH of 3.5 to 4.2, preferably 4.0, and, by addition of a gaseous oxidant (6), a partial oxidation of calcium sulphite is carried out and, by the further oxidation-related reduction of the pH and/or further pH reduction by a mineral acid to pH 1.5-2.5, decomposition of the non-oxidized calcium sulphite with formation of SO2 is effected and thus the reduction of FeIII to FeII occurs, the supply of the oxidant being shut off during the reduction phase and excess liberated SO2 being circulated to the reaction vessel (4). <IMAGE>
Patent DE-3530259-A1 (DE)
Title: Laser controller
Inventor: SEATON NORMAN THEODORE
IPC: H01S3/137
Filed: 1985-08-21
Abstract: An active laser is locked to an ultra-stable reference laser with respect to an offset frequency by means of a comparison circuit having a virtually unlimited catchment range in order to preclude positive phase synchronisation to a harmonic or a mirror frequency of the desired offset frequency. The frequency of such a locked laser is then largely immune to its own light being reflected back into its resonant cavity, and its frequency stability is then just as high as that of the reference laser. Furthermore, the reference laser is preferably stabilised against its own light being reflected back, by means of a method in which objects are selectively displaced in the path of the reference laser beam, Doppler-shifted radiation which is reflected back is detected and suitable optical control means are inserted into the beam path in order to prevent radiation which has been reflected back arriving at the reference laser cavity. A multiplicity of laser systems are specified, in the case of which the active laser is arranged both in a parallel relationship and in a series relationship with respect to a reference laser.

Title: Bypass element
Inventor: PETRI GUENTHER FRIEDRICH
IPC: H02J7/00
Filed: 1985-12-04
Abstract: A bypass element (1) for electrically conductive components (20). It is the object of the invention to construct the bypass element (1) in such a manner that only a very very small current flows through it as long as the components (20) are fully functional. The bypass element (1) is formed by a semiconductor component (2) which exhibits a minimum reverse current. The semiconductor component (2) is partially embedded in a metallic component (3) which is formed by a layer of copper or two layers (3B, 3C) of aluminium and copper. If the impedance component (20), with which the bypass element (1) is connected in parallel, becomes high, the bypass element (1) takes over the entire current. At the same time, its current cross-section is widened so that its resistance is lowered. <IMAGE>

Title: Exhaust system on an air-compressing internal combustion engine
Inventor: BERGMANN HORST DIPL ING
IPC: F01N3/025
Filed: 1986-03-22
Abstract: The invention relates to an exhaust system on an air-compressing internal combustion engine with soot filters in an exhaust pipe divided into two pipe lines. The exhaust gas flow from the internal combustion engine and that from a combustion chamber are alternately deflected to the soot filters by means of pivoted flaps. The exhaust pipes open into a common tailpipe downstream of the soot filters. In order to prevent contamination of the combustion chamber by the exhaust gas flow from the internal combustion engine, in static phases of the combustion chamber ambient air is drawn through the combustion chamber and through the exhaust pipe area with the regenerated soot filter by means of a nozzle formed on the tailpipe side of the exhaust pipes.
Patent DE-3612745-A1 (DE)
Title: Tumbling apparatus
Inventor: THIELE HORST DIPL ING
IPC: B24B39/02
Filed: 1986-04-16
Abstract: A tumbling apparatus for smoothing the surface of workpieces is described, in which a roller cage equipped with rollers is fixed on a face of the head region of an elongated housing. A clamping element, which is connected to the housing via a pin which is assigned a spring element, is arranged longitudinally displaceably on the housing. By tensioning and relaxing the spring element, the clamping element is displaced on the housing. By means of an oblique bearing surface on the clamping element, the setting angle with respect to the workpiece to be worked is ensured. By means of radial and axial support of the rollers at the periphery of the roller cage, a largely floating and thus low-friction bearing of the rollers is achieved.
