The method comprises conducting a process fluid through the one or more reaction tubes, providing several variable voltages at the several power connections, wherein the several voltages are provided as phases of a multiphase AC voltage so that the at least one connecting element forms a star point, setting the one or more voltages; detecting one or more measured values corresponding to one or more measured variables; changing the several set voltages so that the detected measured values correspond to predetermined values or value ranges of the measured variables.

Abstract: A reactor has a reactor vessel and one or more reaction tubes. One or more power input elements are guided into the reactor vessel for the electrical heating of the reaction tube(s). The one or more power input elements each have a rod-shaped section, and the rod-shaped section(s) each run in a respective wall passage through a wall of the reactor vessel. A connection chamber into which the rod-shaped section(s) project is arranged outside the reactor vessel and adjacent to the wall of the reactor vessel through which the rod-shaped section(s) run in their wall passages. Gas feed means apply an inerting gas to the connection chamber, and the wall passages with the rod-shaped sections received therein in a longitudinally-movable manner are designed to be gas-permeable so that at least a portion of the inerting gas fed into the connection chamber flows out into the reactor vessel.

Abstract: A reactor for carrying out a chemical reaction has a reactor vessel, one or more reaction tubes and means for the electrical heating of the one or more reaction tubes. The reactor vessel has one or more discharge orifices which are permanently open or are set up to open above a preset pressure level, and gas feed means are provided, which are set up to feed an inerting gas into an interior of the reactor vessel.

Abstract: A reactor includes a reactor vessel and one or more reaction tubes A number of tube sections of the one or more reaction tubes in each case run between a first region and a second region in the reactor vessel. For the electrical heating of the tube sections, the tube sections in the first region can be electrically connected to (a) current connection(s) of a current source. In the first region, current feed arrangements are provided; in each case one or in each case one group of the tube sections are electrically connected, and each comprise (a) contact passage(s) that in each case adjoin(s) at least one of the tube sections in the first region. A wall of the contact passages in each case is connected to a current feed element that has a rod-shaped section that runs at a wall passage through a wall of the reactor vessel.

Abstract: A process is disclosed for the production of hydrocarbons with removal of coke from a product stream. In a first mode, hydrocarbons and steam are subjected to steam cracking to obtain a cracked gas. The removal of coke from the steam is performed using a coke trap thus obtaining a coke-depleted cracking gas which is subjected to quench heat exchange in the first mode downstream of the coke trap, effecting cooling. Product stream is formed in the first operating mode using the cracked gas cooled in the quench heat exchange. The coke trap is emptied in a second mode using a stream extracted from a cracking furnace, bypassing the quench heat exchange, to obtain a coke stream. The coke stream in the second mode is passed to a coke collector.

Abstract: A radiotherapy installation is described, with a treatment head which is arranged on a treatment head support and which has an exit port for a beam generated in a beam generator, and with a patient table. The treatment head support is guided on a first rectilinear guide, which is guided on a second rectilinear guide arranged perpendicular to the first rectilinear guide, in order to move the treatment head relative to the patient table during the radiotherapy.

Abstract: In a radio network, in which devices transmitting data seize one of a plurality of available frequency channels for the duration of the data transmission, during breaks between the individual data transmissions the frequency channel used is additionally seized in order to signal the seizure of the frequency channel to devices of another radio network. The seized frequency channel is monitored for the attempt of seizure by a device that is not part of the radio part and the additional seizure of the frequency channel is performed as a function of the detection of such an attempt.

Abstract: An arrangement including a receptacle part (1) and a connecting body (2), wherein the connecting body (2) has a base body (3) having an inside surface (5) which is in contact with an outer surface (6) of the receptacle part (1). The base body (3) includes a thermoplastic elastomer connected to the outer surface (6) of the receptacle part (1). The outer surface (6) is designed to be rough enough so that the thermoplastic elastomer will enter into a form-fitting connection and/or an adhesive bond with the outer surface (6) after softening and then solidification.
