Abstract: A method for determining the rotational speed and the angle of rotation of a motor shaft of a mechanically commutated DC motor from the measured progression of time of the ripple in the motor current and in the motor terminal voltage occurring during the commutation. A motor state model of the DC motor, to which the measured motor terminal voltage and the measured motor current, an estimated load torque, an estimated rotational speed and an estimated angle of rotation of the DC motor are supplied to a Kalman filter as input variables. By running the motor state model, the Kalman filter provides an estimated current, an adjusted rotational speed and an adjusted angle of rotation of the DC motor as output variables.

Abstract: A limiter for high-frequency signals has an input, whereas the high-frequency signal is supplied to the limiter at its input. The limiter provides several limiting stages which are electrically connected to the input. Each limiting stage is a series circuit with an unbiased diode and a Zener diode which does not serve to bias the diode, so that the high-frequency signal is electrically connected to a reference ground via the one unbiased diode and the Zener diode.

Abstract: It is provided a method, including deciding, based on a previously estimated interference value, whether a user equipment or a sounding reference signal or a channel of a received uplink signal is affected by a colored interference more than a first predefined threshold, wherein colored interference is an interference having a spatial and/or spectral predominance; and suppressing interference rejection combining on the uplink signal if none of the user equipment, the sounding reference signal, and the channel of the received uplink signal is affected more than the first predefined threshold.

Abstract: A motor vehicle has a support structure formed of a chassis frame and a vehicle body. The chassis frame and vehicle body are bolted together by four bolt locations in the area of upper supports of the spring struts of the front and rear axle. The chassis frame and vehicle body are also glued to each other along segments of the support structure thereof extending parallel to each other, wherein adhesive surfaces are located in the area between the front and rear bolt locations. The adhesive in the middle area of the motor vehicle ensures a large surface area for force application from the chassis frame into the vehicle body and vice versa, which is supplemented by the bolt locations outside of the adhesive joint.

Abstract: An apparatus for dismantling a radioactively contaminated tubular installation part which is located under water contains a base part which can be fixed to the installation part and in which a rolling cutting apparatus is mounted. The rolling cutting apparatus can be positioned in or on the installation part and has at least one cutting roller which can be moved to the inner or outer surface of the installation part and can be moved along it. The apparatus can be used to dismantle and remove even installation parts to which access is difficult, for example the cyclones which are installed in the water/steam separator of a boiling water reactor.

Abstract: Sequences that respectively comprise different data are transmitted via a transfer medium, the transfer quality being detected in accordance with the transmitted sequences. Accordingly, the sequences to be transmitted are assigned to several chronologically sequential stages, the sequences that are assigned to one stage having a pre-definable interval in terms of the data transfer rate. The following steps are executed cyclically: a) transmission of at least part of the sequences that are assigned to the first stage and selection of an interval that is situated between two transmitted sequences, in accordance with the determined transfer quality; b) transmission of at least part of the sequences that lie in the selected interval and that are assigned to the subsequent stage. Thus an optimal data transfer rate can be accurately determined for the transmission of information via the transfer medium.

Abstract: A locking ring holds a control rod drive housing tube of a nuclear power plant when a pressure chamber having a contact wall is pressurized. The contact wall faces the control rod drive housing tube presses against it when the pressure chamber is pressurized. The locking ring can lock a threaded nut after it has been screwed onto the control rod drive housing tube. In a method for securing a threaded nut of a control rod drive housing tube of a nuclear power plant in the vicinity of the threaded nut, a body is attached to the control rod drive housing tube, as a result of a contact surface of the body engaging the control rod drive housing tube. A contact surface of the pressure chamber is pressed onto the control rod drive housing tube when the pressure chamber is pressurized.

Abstract: A method for identifying a measured value of a velocity or speed of an object where a measured value call-in can occur at any time. A chronological spacing of measuring pulses of a speed sensor is measured and a measured value is formed therefrom. The measurement is carried out until either a measured value call-in occurs, a maximum number of measuring pulses is registered, or a maximum measuring duration is exceeded. When no measuring pulse or only one measuring pulse is registered, a distinction is made in the formation of the measured value as to whether a measuring duration corresponding to a minimum velocity or minimum speed is upwardly or downwardly crossed. An initial counter reading is stored at every measuring start and at every first registered measured pulse. A final counter reading is stored at every further registered measuring pulse until either a measured value call-in occurs or the maximum measuring duration is exceeded.

Abstract: A gripping tool for a device for the remote-controlled removal of samples in housings with heads from a container includes a mast having a first coupling part. A second coupling part is opposite and associated with the first coupling part. A guide bar elastically bears on the second coupling part in a telescoping manner with pivots disposed on the guide bar. At least two catches of a two-armed lever are disposed on the pivots and have guide grooves formed therein. A bushing surrounding the guide bar has guide pins each engaging a respective one of the guide grooves. At least one remotely controlled linear drive moves the bushing in the direction of the longitudinal axis of the bushing for surrounding the head of the sample housing with the catches like tongs.
