  • Patent number: 8627718
    Abstract: The invention relates to a sensor arrangement for determining a tank fill level of a liquid, especially a reducing agent for removing nitrogen from the exhaust gases of an internal combustion engine, which liquid is contained in a tank, at least two electrically conductive measuring electrodes being at least partially embedded in a carrier that is produced of an electrically non-conductive material. The sensor arrangement includes a temperature sensor, especially a resistor with negative temperature coefficient being used as a temperature sensor, which is integrated into the carrier.
    Type: Grant

    Date of Patent: January 14, 2014
    Assignee: Robert Bosch GmbH

  • Patent number: 8435618
    Abstract: An injection-molded part according to the invention has at least one thermoplastic inlay part and one thermoplastic composite element injection-molded onto the inlay part. The at least one inlay part on its boundary face with the composite element has at least one raised feature for material-locking sealing between the inlay part and the composite element. The raised feature protrudes with a height H1 into the composite element and forms a narrowed cross section in the composite element having a height H2. The at least one raised feature, on its flux leading end, has a first chamfer, and the ratio of the height of the narrowed cross section to the height of the raised feature is in the range between 0.6 and 0.9.
