Patent number: 5005402Abstract: A device for the determination of the alcohol content and/or the calorific value of fuels by measuring the characteristics of the fuel in a measurement cell in which a flow body that is at least partially wetted by the fuel is arranged. The accuracy and speed of this measurement is improved by providing a first electrode for the dielectric measurement of the fuel and a second electrode for the measurement of the conductivity of the fuel on the outside of the flow body. Preferably the first electrode for the measurement of the capacitance, its outer connection and the walls of the measurement cell form a mechanically rigid system. It can also be expedient to mount the measuring circuit for the measurement of at least the capacitance directly on the housing of the measurement cell.Type: GrantFiled: December 6, 1989Date of Patent: April 9, 1991Assignee: FEV Motorentechnik GmbH & Co.

Patent number: 4811523Abstract: An apparatus for fine machining of plane surfaces of disk-shaped workpieces having an unmachined bearing side and a slight wall thickness is described. The apparatus is provided with a chuck, preferably realted, for receiving the workpiece and a cup wheel. To assure that the pieces are supported over a defined and sufficiently large area to prevent both tilting during the machining and bending due to the machine pressure, so that a surface of highly accurate shape is attainable, the chuck for receiving the workpiece is provided with three fixed support pins distributed over the circumference and against which the workpiece is pressed. Between the three fixed support pins, a plurality of further support elements are provided, which can be supportingly fixed against the bearing side of the workpiece once the workpiece has been placed upon the three fixed support pins.Type: GrantFiled: April 21, 1986Date of Patent: March 14, 1989Assignee: Supfina Maschinenfabrik Hentzen KGInventors: Heinz-Gunter Schmitz, Johann Konken

Patent number: 4516757Abstract: A tiltable metallurgical vessel is rotatable about pivot pins which are supported in bearings. At least one of the pivot pins is hollow so that a material carrying conduit can pass through the pivot pin desired materials from a remote source to a desired operational site of the furnace. In addition, other material carrying conduits are provided to the operational sites of the furnace. These latter conduits are connected, at one end, to stationary tapping points and, at the other end, to the operational sites of the vessel. The conduits are guided around (by being coiled by at least one full turn) an enlarged cylindrical portion of the hollow pivot pins.In one embodiment of the invention, the enlarged cylindrical portion of the hollow pins are winding drums which are themselves constructed of symmetrical cylinder halves. In this manner, the winding drum can be easily retrofitted onto a preexisting vessel.Type: GrantFiled: December 9, 1981Date of Patent: May 14, 1985Assignee: Mannesmann AktiengesellschaftInventors: Karlheinz Langlitz, Gunter Schmitz

Patent number: 4491074Abstract: A vehicle for transporting heavy loads on parallel tracks is disclosed. Two of the wheels of the vehicle are fixedly mounted to the vehicle frame, while the remaining wheels are mounted so that they can vertically adjust to deviations in the height of the rail track. In this manner, heavy loads can be transported on the rail tracks without any particular wheel becoming overloaded.In the preferred embodiment, the adjustable wheels are supported by bell crank levers which are themselves connected to one another by a parallelogram linkage arrangement.Type: GrantFiled: January 25, 1982Date of Patent: January 1, 1985Assignee: Mannesmann AktiengesellschaftInventors: Wilhelm Ackermann, Karlheinz Langlitz, Gunter Schmitz

Patent number: 4268014Abstract: A truck is provided for transporting and lifting heavy metallurgical vessels from one place to another. The truck combines two functions ordinarily provided by two different trucks, in that the truck of the invention lifts and/or removes the vessel from its tilting mount for relining and when replacing it on the mount also refits the bottom plate and cover onto the vessel, the latter function usually being carried out by a separate truck. The arrangement includes a separate bottom plate carrying device configured to be positioned on the truck. The carrying device is positioned to be non-displaceable on the lifting mechanism and to be, when thus placed, subject to the centering and lifting mechanisms of the truck of the invention.Type: GrantFiled: January 10, 1980Date of Patent: May 19, 1981Assignee: Mannesmann Demag AGInventors: Karlheinz Langlitz, Gunter Schmitz

Patent number: 4266758Abstract: A support is provided for a metallurgical vessel, in which paired tie rods are provided superimposed upon each other to absorb the stress resulting from thermal expansion and contraction in the support. By superimposing pairs of the tie rods upon each other and pre-stressing them, a substantial capacity is provided for absorbing built-up stresses in the support while requiring relatively less space for accommodating the tie rods. The paired compression heads and tie rods are positioned concentric to each other on the same axis.Type: GrantFiled: February 4, 1980Date of Patent: May 12, 1981Assignee: Mannesmann Demag AGInventor: Gunter Schmitz

Patent number: 4096918Abstract: A metallurgical tilting vat, such as a steel mill converter, which, by means of vat extensions or projections, rests on a surrounding tilting mechanism, so that it can be tilted 360.degree., and where radial and axial heat expansion and contractions are accommodated. The tilting mechanism is equipped with dynamic test cells for weighing the vat and/or vat contents. This type of metallurgical tilting vat equipped with weighing devices serves to ascertain the vat contents in order to observe the steel production process based on differing weights of the vat contents, and, in turn, to regulate the decarbonization process based on the weight data and/or data graphs thus obtained.Type: GrantFiled: February 4, 1977Date of Patent: June 27, 1978Assignee: Demag AktiengesellschaftInventors: James Ingram Beggs, Karlheinz Langlitz, Gunter Schmitz, Wolfgang Jansa
