  • Electromagnetic actuator for a speaker or a sound transducer with a multimetal layer connection between the voice coil and the magnet system
    Patent number: 11838736
    Abstract: An electrodynamic actuator for a speaker or an electrodynamic acoustic transducer in general is disclosed, which comprises at least one voice coil, a magnet system and an arm arrangement of a plurality of arms connecting the at least one voice coil and the magnet system or at least a movable part thereof so that a relative movement between these parts is allowed. The arms are made of a metal core, which at least partly is coated with a coating structure having at least one coating metal layer consisting of a different material than the metal core.
    Type: Grant

  • Elastomeric End Frame of a Redox Flow Battery
    Publication number: 20160006046
    Abstract: In order to improve the sealing between an elastomeric end frame (20) and the adjacent stack frame (3) of a cell stack (4) of a redox flow battery, it is provided that on the side of the recess (22) to receive a current collector (21) a first sealing element (25), which extends along the periphery of the end frame (20), is closed in the peripheral direction and protrudes from the first end face (24) of the end frame (20), is integrally molded on a first end face (24) of the end frame (20).
