Abstract: A sliding guide shoe for an elevator includes a two-part insert that can be inserted into a guide shoe housing for guiding an elevator car along a guide rail. The insert has a carrier element with a recess which is designed as a receiving pocket for receiving a sliding element so that the sliding element can be introduced into the carrier element in a longitudinal direction and then latched in the carrier element.

Abstract: A method for communication with a transportation system utilizes a human-machine interface with a control unit that constantly checks for the presence of contactlessly communicating information carriers. If a user with an information carrier is located in the reception range, the control unit requires the information carrier to transfer at least identification data of the user to the control unit. The control unit then displays an individualized communication surface matched to the respective user on the basis of the received data.

Abstract: A glass door leaf for elevator shaft and car doors has a glass pane connected at its lower edge with a guide shoe plate and at its upper edge with a hanger bracket. Eccentric pins with guide shoes are attached to the guide shoe plate and enter into a threshold profile for the sliding guidance of the glass door leaf at its lower end along the displacement path of the door. The glass pane is retained at the lower end between a lower base strip and a glass-retaining strip of the guide shoe plate and retained at the upper end between an upper base strip and the hanger bracket. Rubber bushings extend through apertures formed in the glass pane and encompass fastening nuts which are inserted from the elevator shaft side and are connected with welding pins attached to the base strips. A carrier holds a guide rail which extends along the displacement path and engages rollers which carry the glass door leaf and are mounted on the hanger bracket.

Abstract: In this drive control the regulating circuits for the rotational speed of a drive motor and of an eddy current brake are matched in their static and in their dynamic behavior so that a common regulator may be used for both regulating circuits. The matching is achieved by interposing a current regulation circuit for regulating the excitation current of the eddy current brake to the rotational speed regulating circuit. The output of the common regulator is supplied via a linearization member as a reference value to a regulator in the current regulation circuit during the deceleration phase. During the acceleration phase the output of the common regulator is supplied to a matching element matching the variation of the torque to the variation of the torque during the deceleration phase with respect to time. The output of the matching element is connected to the control member of the drive motor via a linearization member. By means of the linearization members the characteristics of a d.c.
