A method for determining the direction of the earth field, the north direction and the travelling direction of a vehicle by way of a magnetometer mounted in the vehicle is based on dynamic compensation or updating of interfering field changes. For this purpose, a resultant vector (v.sub.K) is formed from the magnetic field vector (V.sub.M) effective at the magnetometer, the previous hard-magnetic interfering field vector (H.sub.H) and the nominal vector (V.sub.P) determined from the circle diagr…

A twisting device for power looms comprises oppositely moving heddle supporting rails, two lifting heddles arranged on the heddle supporting rails for standing threads, a semi-heddle for turning threads controlled separately from the heddle supporting rails. It also has a coupling part having magnetic properties and arranged so that the semi-heddle is supported through the coupling part on both the lifting heddles in a longitudinally displaceable manner, and two countercoupling parts having magn…

A continuous microfilming apparatus comprising a filming station, means for feeding documents to be microfilmed to the filming station, means for collecting the documents after they have been filmed, and means for transporting the documents from the filming station to the collecting means and turning the documents over substantially 180.degree. while transporting them, which transporting and turnover means includes a transporting reel defining a turnover path of substantially 180.degree. andd fl…

A sealing device is provided on the outer circumference of an oil pressure unit of the oil pressure rush adjuster, or on the partitioning wall of a sub-reservoir surrounding the oil pressure unit, or therebetween so as to provide a sealing between said partitioning wall and said outer circumference of the oil pressure unit while the engine in which the rush adjuster is mounted is stopped and so as to allow a portion of the oil to leak therebetween while the engine operates. Since the oil is perf…

In the method for the production of an aromate concentrate suitable for use as blending component for gasifier fuel, feed hydrocarbon mixtures having boiling ranges substantially between 40.degree. and 170.degree. C., are subjected, without any previous separation into individual fractions, to an extractive distillation employing N-substituted morpholine, substituents of which display no more than seven C-atoms, as selective solvent. Herewith, the lower boiling non-aromates with a boiling range …

In accordance with a method of producing of methanol synthesis gas from a partial oxidation crude gas, the gas is cooled after a waste heat boiler of a gasifier by adding a converted circulating gas in a quenching zone. The resulting gas mixture is dedusted and then separated into a product gas partial stream and a circulating gas partial stream. The product gas partial stream is supplied after corresponding gas treatment to the synthesis reactor while the circulating gas partial stream is subje…

An insertable hub-shaped bracing device for preserving the shape of large coils, consisting of a circular disk having a U-shaped cross-section and a cylindrical opening in its center, the disk being insertable in the cylindrical cores of large coils.
