Abstract: Implementations of a tube, a baffle, and a baffle inserter are provided. In some implementations, the tube comprises one or more slots and a plurality of sidewalls that extend down from the outer surface of the tube into the tube on each elongated side of the slots. In some implementations, the baffle inserter comprises a baffle holder pivotably attached to a base at a first end where a portion of the base at the first end is slanted and a portion of the baffle holder is configured to rest on the slanted portion in a first position. In some implementations, to insert a baffle into the tube using the baffle inserter, the baffle is placed on the baffle holder in a first position and the baffle inserter is inserted inside the tube until the baffle contacts a stopper and pivots to a second position under a covered portion between two adjacent slots in the tube.

Abstract: A concatenation module adapted to be concatenated with further concatenation modules as a battery, comprising a housing and lateral concatenation contacts on the housing for making electrical contact with at least one further concatenation module. The housing is in the form of a three-dimensional circuit substrate and it contains at least one electronic component, arranged on the circuit substrate, for a control function and/or a monitoring function and/or a communication function. When the concatenation modules are assembled as a battery the concatenation contact preferably make flatwise contact with each other.

Abstract: A circuit device for the regulation of the coil current flowing through a solenoid coil arrangement is proposed. It comprises a regulating means having a measuring arrangement for measuring the coil current and adapted to regulate the coil current in a manner dependent on the measured coil amperage, means for producing a attraction current, which regulated by clock pulse switching, flowing through the solenoid coil arrangement and a switching over means for reducing the coil current after elapse of an attraction time to a lower clock pulse switched hold current flowing until the end of a switch signal. The measuring arrangement is switched outside the freewheel circuit in which during the freewheel condition, existing in clock pulse switching intervals, of the solenoid coil arrangement the freewheel current flows. This means that the input voltage does not have to be adapted to the desired attraction current and the freewheel current does not produce any power loss in the measurement arrangement.

Abstract: A plug connector having a main body, which has at least one connecting unit including an opening delimited at the side of an elongated transversely elastic gripping rib. The opening constitutes a plug socket, into which a plug element may be inserted and acted upon by the gripping rib. The gripping rib has a concave shaped longitudinal edge portion facing away from the plug socket such that the width of the gripper rib increases toward the two ends of the rib.
