A starting element () for use, for example, in a drivetrain of a motor vehicle, includes a piston () which divides a first volume () that can be filled with a fluid from a second volume () that can be filled with a fluid, wherein the piston () comprises at least one fluid passage () which allows the fluid at least occasionally to pass through the piston () from the first volume () into the second volume () and/or from the second volume () into the first volume (). The at least one fluid passage () comprises a passage component part () and a receiving opening () in the piston (). The passage component part () is inserted into the receiving opening so that at least one passage opening () is formed which allows the fluid to pass through at least occasionally.

A torsional vibration damper arrangement includes a vibration damper device () having a deflection mass carrier () and at least one deflection mass () which is supported at the deflection mass carrier () such that it can be deflected out of a basic position at a maximum distance from the axis of rotation (A) into a deflection position at a shorter distance from the axis of rotation (A), wherein the secondary side () has at least one circumferential supporting element (') having at least one circumferential supporting region () and a secondary-side mass element () which is preferably shaped like an annular disk. First connection elements () connect the secondary-side mass element () to the at least one circumferential supporting element () and to the deflection mass carrier ().

A process and device for monitoring the bobbin thread on stitch-forming machines, on the bobbin of which a residual amount of thread is wound in a winding direction opposite the direction of winding of the principal amount of thread, is to ensure that a first control function will be generated at the beginning of consumption of the residual amount of thread, and a second control function is generated nearly without delay in the case of thread end or thread break. To achieve this, two signal patterns are received with a phase shift from a bobbin acting as a signal generator, and the first signal function is generated in the case of a deviation of the actual phase shift from the desired phase shift. If only one signal pattern is received, this first control function is also generated if its signal sequence deviates from a reference signal sequence. The second control function is generated if a stoppage of the bobbin lasts longer than a predeterminable number of stitches. Devices for carrying out this process, as well as a device for winding thread on the bobbin in different directions of rotation for the principal amount of thread and the residual amount of thread are provided.
