  • Patent number: 5793199
    Abstract: A method of determining a concentration of magnetic powderly material in a sample is disclosed. In this method, a pair of series-connected exciting coils are disposed in such a manner that magnetic fields generated from the respective exciting coils oppose to each other. A detecting coil is disposed at a position where the magnetic fields from the pair of exciting coils cancel out each other. A sample mixed with magnetic powder is inserted into one of the pair of exciting coils. Then, the method detects a voltage induced in the detecting coil in association with the insertion of the sample into the exciting coil and determines the concentration of the magnetic powder in the sample based on the detected voltage.

  • Patent number: 5790970
    Abstract: A movement variable which represents the movement of a vehicle is controlled by actuating at least one actuator for applying a braking force to the wheels. Controller means use controller internal variables to form signals for influencing the actuators with the effect of adjusting a control variable. The controller means has a first area adapted to the respective selected sensor configuration in such a way that the controller-internal variables are formed on the basis of the sensor signals, and a second area for processing the controller-internal variables independently of the selection of the sensor configuration. As a result, simple adaptation with low development and application outlay to a wide variety of sensor configurations is possible.

  • Patent number: 5788730
    Abstract: A silicon-containing glass starting material is fed through a central area of a multi-nozzle burner head while the fuel gases are fed through an outer area surrounding the center. In a reaction zone near the burner head, fine SiO.sub.2 soot particles are formed, which are deposited on a carrier to build up a porous soot body, which is then sintered. During the process of building up the soot body, the fuel gas stream is varied to achieve a desired radial or axial density profile in the soot body. To separate the glass starting material from the fuel gas in the area extending from the burner head to the reaction zone, a barrier gas stream is provided between the burner gas stream and the stream of glass starting material. The burner head has a central, tubular nozzle and several ring nozzles arranged coaxially around it. Between the central nozzle and the ring nozzles, a ring-shaped barrier gas nozzle is provided, which has inner and outer boundary walls which are circular in radial cross section.

  • Patent number: 5789670
    Abstract: In a moisture sensor (1), the effective sensor field (4) is formed by two sensor elements (8a, 8b,) having interdigitating parallel tracks. These sensor elements consist of layers of a metal nitride compound, especially a chromium-nitrogen compound, deposited by means of magnetron cathode sputtering or glow discharge onto a dielectric substrate (2), the metal nitride layers being deposited onto the substrate surface which has first been cleaned by ion sputtering. These sensor element layers (8a, 8b) have a high hardness of about 2,000 on the Vickers scale, as a result of which the sensor elements (8a, 8b) are highly resistant to abrasive wear such as that caused by windshield wipers or scratching from ice. The moisture sensor can be produced with a low electrical surface resistivity of <100 ohms.quadrature. and is chemically stable with respect to environmental effects such as salt water and/or windshield cleaning fluids.

  • Patent number: 5778961
    Abstract: During the simultaneous casting and directional solidification of several castings in pre-heated casting moulds (11), these standing around a central cavity (H) on a ring-shaped cooling plate (5) after pouring off are continuously removed from a heating chamber (14) by a vertical movement relative to the heating chamber in accordance with the solidification temperature and the castings are cooled by heat radiation to below the solidus temperature. In order to increase the production rate and the product quality, the casting moulds (11) are moved over a firm heat sink (9) during the directional solidification by continuous relative movement of the cooling plate (5), said heat sink thereby penetrating into the cavity (H).

  • Patent number: 5779328
    Abstract: In a brake system with a controllable hydraulic pump in a hydraulic circuit, and with at least one solenoid valve, the operating state of the valve is changed in response to a control signal. As a result of the change in the operating state of the solenoid valve, the flow resistance in the hydraulic circuit is changed. Monitoring structure is provided which, in the presence of certain operating conditions, monitor the run-down behavior of the hydraulic pump in different operating states of the solenoid valve and actuate a display device to display a malfunction of the brake system when a malfunction is detected. Additionally, or alternatively, the automatic brake control can be turned off in reaction to the detection of a malfunction. It is possible for the control unit and the hydraulic unit to be replaced separately and for the installation to be tested for proper functioning.
