  • Magneto-mechanical power system
    Patent number: 5864274
    Abstract: A magneto-mechanical power system including a cylindrical soft-iron vessel with permanent magnets arranged to form a shunt-magnetic gap with the inside wall the soft-iron vessel. The neck of the flux conducting disk is surrounded by a current winding. A magnetically attractable pole disk lies on the neck of the soft-iron vessel. An electrically conducting ring is fastened to the pole disk. The pole disk activates mechanical and/or electrical safety devices. The system is activated by a current impulse sent to the current winding. Current in the current winding creates a field that displaces the magnetic flux path of the permanent magnet.

  • Boring tool
    Patent number: 5857813
    Abstract: A boring tool for the fine finishing of surfaces of holes having at least one cutting bit and at least one guide ledge which are introduced and fixed in place in grooves arranged in the circumferential surface of the base body of the boring tool, characterized by the fact that a setting device is provided which is positively coupled with at least two cutting bits associated with each other; that the cutting bits are arranged displaceable by means of the setting device in the base body with respect to the circumferential surface; that the association of the cutting bits consists in that they are displaceable in opposite directions, with respect to the axis of rotation or center line of the boring tool; and that the setting device in each case displaces one cutting bit into a working position and the other cutting bit into a position of rest.

  • Radiation-sensitive detector element and method for producing it
    Patent number: 5852322
    Abstract: A radiation-sensitive detector element has an active area which is formed between two adjoining layer areas of a layer arrangement and within which a conversion of incident electromagnetic radiation into electrical signals takes place. Taking into consideration the penetration depth of the radiation, the position of the active area in relation to the two limiting surfaces is selected in such a way that at least two layer areas for connecting the detector element to an evaluation circuit can be mounted on a surface located opposite the radiation-sensitive surface which is impinged by the incident radiation.

  • Cylinder head arrangement of an internal-combustion engine
    Patent number: 5845616
    Abstract: The cylinder head arrangement of an internal-combustion engine consists of at least two housing components which are arranged on one another in a common flange plane. Adjacent this flange plane, indentations extend in the respective flange surfaces and may, for example, be cast in. In the flange plane, the two flange surfaces are separated from one another by an inserted seal so that at least two mutually separated duct sections are formed which are used for the oil supply of the cylinder head arrangement.

  • Method and apparatus for operating a hydraulic drive
    Patent number: 5845493
    Abstract: The drive includes a reversible variable output pump (1), which supplies a hydraulic working machine (6) and is driven by an asynchronous motor (2). The working machine is intermittently hydraulically pressurized. During these times the asynchronous motor can be switched off since the subsequent start-up process, which causes a high current consumption in the case of asynchronous motors, is effected by the variable output pump. Before the beginning of the start-up process the variable output pump is preset to the maximum negative discharge rate by its proportional valve (10) being acted on by a control pressure. The volume pressurized in the working machine is then applied to the output side of the variable output pump. The asynchronous motor is connected to the current supply network after reaching a minimum speed.

  • Method and apparatus for generating and receiving electromagnetic waves for testing purposes
    Patent number: 5844413
    Abstract: The invention describes a method and an apparatus for generating and receiving electromagnetic waves for test purposes and is applicable particularly for measurements, investigations and tests of electromagnetic compatibility. For testing the immunity, the test piece is acted upon with defined field parameters and, during the emission measurement, the electromagnetic radiation emitted by the test piece is measured. It is an important distinguishing feature of the invention that a cell, constructed as a TEM waveguide, is rotated about the test piece. The apparatus is characterized in that the lid and bottom of the pyramidal cell are constructed so as to be electrically conducting and in that two-dimensional septa, which consist of individual wires of equal length, are disposed in each case symmetrically at a small distance from the lid and the bottom.
