  • Patent number: 10935065
    Abstract: A method for setting a screw, which has an external thread in a front region and a drive in a rear region for introducing a torque into the screw, in a drilled hole in a substrate of a mineral material includes producing an internal thread in the drilled hole by a threaded drill provided with a cutting thread and then introducing the screw into the drilled hole and in so doing the external thread of the screw is screwed into the internal thread, produced by the threaded drill, in the drilled hole. The external diameter of the cutting thread of the threaded drill is smaller than the external diameter of the external thread of the screw.

  • Publication number: 20180231045
    Abstract: The invention relates to a method for setting a screw, which has an external thread in a front region and a drive in a rear region for introducing a torque into the screw, in a drilled hole in a substrate of a mineral material, in which method an internal thread is produced in the drilled hole by means of a threaded drill provided with a cutting thread, and then the screw is introduced into the drilled hole and in so doing the external thread of the screw is screwed into the internal thread, produced by the threaded drill, in the drilled hole. According to the invention, there is provision that the outside diameter of the cutting thread of the threaded drill is smaller than the outside diameter of the external thread of the screw. The invention further relates to packages comprising object for carrying out such method.

  • Patent number: 6928854
    Abstract: A method for detecting a malfunction of a sensor measuring a measured quantity is provided, in which a signal-range check for the output signal of the sensor is performed, provided that the measured quantity is within a permissible range. If the measured quantity is outside the permissible range, no signal-range check is performed, but the output signal is used for detecting the measured quantity and for further calculations. The sensor may be, for example, a hot-film air-mass meter. If this is the case, the measured quantity is the drawn-in air mass, and the signal-range check is performed, provided that the engine operating state and thus the drawn-in air satisfies specifiable conditions. In addition to the signal-range check, onboard diagnoses with regard to specifiable plausibility criteria relating to the offset-drift and/or the sensitivity-drift of the sensor may also be performed.

  • Patent number: 6571613
    Abstract: A method and a device for controlling an internal combustion engine. A temperature variable and a pressure variable are detected by sensors. On the basis of at least the temperature variable and the pressure variable, a first quantity is determined that characterizes the air quantity, which is supplied to the internal combustion engine. A further sensor detects a second quantity that characterizes the air quantity, which is supplied to the internal combustion engine. The second quantity is adapted by the first quantity. Furthermore, the first quantity is used as a substitute value for the second quantity.
