  • Patent number: 12655264
    Abstract: The invention relates to a reactor arrangement and to a method for decomposing objects of plastic-based composite materials into their individual constituents by way of a solvolysis using at least one reactor chamber in which the objects as exposed to a solvent in the supercritical state. The invention is characterized in that at least three pressure chambers located in series, a first load lock chamber, a reactor chamber adjoining the same, and a second load lock chamber adjoining the latter, which are each connected to each other via an actuatable partition which can be moved from an open position, in which two of the mutually adjacent pressure chambers are connected to each other, to a closed position, in which two of the mutually adjacent pressure chambers are fluidically, thermally and pressure-specifically isolated from each other.

  • Patent number: 12283866
    Abstract: An electronic control unit is provided for an electric power steering system. The electric power steering system includes a housing and an electric motor. The electronic control unit is arranged inside the housing and is electrically connected to the electric motor. The electronic control unit includes a first power board having a first electric motor connector for electric connection with the electric motor, and a second power board having a second electric motor connector for electric connection with the electric motor. A connector plate of the electronic control unit is electrically connected by at least one plug connector to the first power board via at least one first power connector, and to the second power board via at least one second power connector. The at least one first power connector is shorter than the at least one second power connector. An electric power steering system is also provided.

  • Publication number: 20050060438
    Abstract: A computer program of the type commonly known as a “wizard” is disclosed that initializes user interface software for controlling an audio conferencing device. The wizard allows the desired audio inputs (e.g., microphone, telephones, etc.) and audio outputs (speakers, recording devices, etc.) to be chosen by an audio system administrator. Thereafter, the wizard allows an audio conferencing device (or devices) to be chosen by the administrator, or allows such a device(s) to be optimally chosen dependent upon the chosen inputs and outputs. The wizard then maps the inputs and outputs to the input and output ports on the audio conferencing device, a step which again can be performed manually by the administrator or automatically by the wizard. After reviewing the mapping results, the administrator finishes the wizard, which computes the mapping parameters and other audio-optimizing parameters for the selected inputs and outputs.
