Patent DE-3309572-A1 (DE)
Title: Straightening and calibrating machine
Inventor: STEINEGGER WERNER
IPC: B21D3/14
Filed: 1983-03-17
Abstract: For the simultaneous straightening and calibrating of sectional steel, in particular support sections removed from mines and tunnels, use is made of an apparatus which comprises a plurality of roller pairs arranged one behind the other, of which at least the first roller pair is designed as a pivoted roller pair. This pivoted roller pair is here allocated to a pivoted frame which, as such, is arranged so as to be displaceable and, as an inner part, has a pivoted support which is guided in the outer frame and can be pivoted or rotated through a predetermined angle. It is thereby possible to straighten the inserted support sections both in the X axis and in the Y axis and then calibrate them in the subsequent roller pairs in such a way that a support section of satisfactory quality is subsequently obtained and can then be used underground again without further ado, in this form or after a subsequent bending operation. <IMAGE>

Title: Pivoting sliding door for vehicles
IPC: E05D15/10
Filed: 1983-04-12
Abstract: The invention relates to pivoting sliding doors for vehicles, with a telescope rail lying in the upper door region, with a guide rail attached to the door leaf at the bottom and curved about a vertical axis in the vicinity of the pivoting-out door edge, with a pivoting roller lever mounted on the run-round doorpost, and with guide rollers which are mounted on the pivoting roller lever between which the guide rail extends. In this construction, an elastic insert is provided in the guide rail. In addition, the movement of the pivoting lever has to be braked by means of a buffer to be adjusted. The object on which the invention is based is to save these parts and to make adjustment easier. This is achieved in that the pivoting lever carries three guide rollers which are located in front of and behind the guide rail, in such a way that the pivoting lever and the door leaf are held stably. The arrangement of the rollers emerges from Figure 2 of the drawing. <IMAGE>

Patent DE-3321515-A1 (DE)
Inventor: FLOETER WILFRIED DR
IPC: C12P3/00
Filed: 1983-06-15
Abstract: Process for transforming sulfur compounds in which the sulfur atom is positively charged, process which is carried out in anaerobic conditions, by using sulfate reducing bacteria in the presence of carbon-containing organic substances, by means of the formation of sulfur or sulfur compounds, of which the oxidation degree is lower than that of the starting sulfur compounds, particularly hydrogen sulfide, and of compounds containing carbonate. It enables a reduction of sulfate compounds at substantially lower cost with respect to known chemical processes so that, on one hand it provides for exploiting large quantities of sulfate produced in the course of numerous industrial processes as starting material for the recovery of sulfur, particularly sulfuric acid, and so that, on the other hand, it simultaneously enables the economical transformation of sulfur compounds which may not be readily deposited into danger-free deposit substances. Hydrogen sulfide produced during the sulfate reduction may be transformed, in another step of the process, into an elemental sulfur under anaerobic conditions and by using of oxidizing bacteria with carbon dioxide.

Patent DE-3333461-A1 (DE)
Title: Flow-adapted dialyser lid
Inventor: SIGDELL JAN ERIK DR
IPC: B01D61/30
Filed: 1983-09-16
Abstract: Dialysers for artificial kidneys using hollow fibre bundles possess terminal connections for the blood flowing in and the blood flowing out, the connections being designed as lids on both ends of the cylindrical housing for the hollow fibres. Usually, these lids have a centrally located nozzle for the blood hose and form a distribution space for distribution of the blood entering at that point to the ends of the hollow fibres in the bundle and, correspondingly, at the outflow end. Previous configurations of these lids were unsuitable from a flow point of view because they caused large variations in the flow rate of the blood within the distribution space and, furthermore, led to detachment of the flow from the axial lid wall. The present invention presents a calculation method for lid configurations without such deficiencies, as a result of which corresponding novel lid contours having improved properties are obtained. For this purpose, the flow fields of 1) the rotationally symmetrical stagnation flow and 2) an extended, circular sink flow are combined, after which the group of flow lines is selected as the lid contour by the edge of the sink region. For calculation purposes, a flow line defining the contour cross-section is determined.

Title: Circuit arrangement for supplying an oscillating-armature motor
Inventor: SCHWARZ GERHARD
IPC: H02K33/00
Filed: 1983-09-17
Abstract: The invention relates to a transistor switch for switching an inductive load, especially the inductance of an oscillating-armature motor, and consists of two transistors whose load paths are connected in series with the inductance and of two diodes, which are likewise connected in series with the inductance, in the opposite direction, and are connected in parallel with a supplying DC voltage source or a rectified AC voltage source. The transistors are driven directly or via an additional transistor or the load path of the other transistor from a pulse generator, preferably a square-wave generator, the energy which is stored in the inductance during the phases when the transistors are switched off flowing back into the supplying DC voltage source or an input capacitor which is connected in parallel with the supplying DC voltage source. The circuit arrangement makes it possible to dimension the active components to a blocking voltage which is slightly higher than the supplying DC voltage.

Title: Method and device for sealing pipelines
Inventor: SCHMIDT MANFRED
IPC: F16L55/163
Filed: 1984-02-08
Abstract: The method is used for sealing a pipeline which runs in bends and from whose internal space a medium which is present in said internal space emerges through a leakage point in a wall surrounding the internal space. In this case, in the region of both ends of a flexibly elastic tubular body, in each case one sealing element is connected to an outer surface which bounds the tubular body. The tubular body is then conveyed through the pipeline to the leakage point with the two sealing elements. There, in each case one of the two sealing elements is sealed to the wall of the pipeline while in each case one side of the leakage point in the longitudinal direction of the pipeline. An annular space into which a repair medium which seals the leakage point is inserted can be bounded by the sealing elements, the pipeline wall and an outer surface of the tubular body facing the pipeline wall. The tubular body can be designed to be permeable to the medium in the flow direction of the medium existing inside the pipeline, so that it can remain permanently in the region of the leakage point. The device according to the method is characterised in that a flexibly elastic tubular body which runs essentially in the longitudinal direction of the pipeline extends through the internal space of the pipeline. The tubular body is guided in a sealing manner in sealing elements. In each case at least one sealing element is fixed in a sealing manner in the pipeline, on both sides of a leakage point in the longitudinal direction of the pipeline. ...

Title: Fuel injection nozzle for internal combustion engines
Inventor: TRACHTE DIETRICH DIPL ING
IPC: F02M61/08
Filed: 1984-03-22
Abstract: Fuel injection nozzle for internal combustion engines, with an outwards opening valve needle (26) and with means (46, 48, 56, 61) for damping the opening movement of the valve needle, which means are so designed and adjusted to one another or to the stroke length and the number of strokes of the valve needle that they form the rate-of-injection curve in the desired way solely by interaction with the injection-pressure curve. A covering on the valve seat can thereby be dispensed with, so that the coke residue products which may form on the front face of the nozzle body cannot have a detrimental influence on the rate-of-injection curve and the injection jet geometry. In injection nozzles which are intended for engines with direct injection, it is especially advantageous if the valve seat angle (b) corresponds to the injection angle or is so adjusted to this that together with the respective combustion chamber optimum mixture preparation is ensured. <IMAGE>

Title: Economical heating system controlled by the actual "set" heating energy use factor
Inventor: FRANCSISKOVITS OSCAR DIPL ING
IPC: G05D23/19
Filed: 1984-08-17
Abstract: The economy of the heating system in fact consists of a continuous comparison procedure of the real "set" heating energy factor, adapted to the outside air temperature by its logarithmical variation. As its economical "set" value is established practically, only so much heating heat is generated or delivered as is actually necessary for economical heating. The precise heating heat supply limitation is made possible because the value of the "set" heating energy factor takes account of almost all heating conditions and influences. The invention also offers, in addition to its main solution, various practical advantages: advance calculation of the annual fuel requirement, fuel costs etc.
