Abstract: Disclosed is a battery cell including an electrode, a housing, a cell interior inside the housing, a temperature sensor, and a heat-conducting part which differs from the electrode, is entirely or partially disposed inside the housing of the battery cell, and is thermally connected to the temperature sensor.

Abstract: In a device for automatically winding up an electrical cable for an electrically operating apparatus on a drum, the drum is journalled with its hollow hub in two sleeve bearings of different diameter formed with a pivot spindle fixed on a base plate. Between the bearings two sliding contact elements comprised of contact rings and contact springs are arranged, of which the contact rings are arranged non-rotatably on the pivot spindle, and the contact springs are arranged in a contact carrier insertable in a recess in the hub. The opening of the hollow drum hub (3.1) facing the base plate (1) is provided with a collar (3.11) and locking pawls (1.2) are provided on the base plate (1) that engage behind the collar (3.11) of the hub (3.1) so that the drum (3) is secured against axial drawing off of the pivot spindle (2). The contact carrier (12) is insertable in a radial direction in the recess (3.12) of the hub (3.1) and is held therein through a locking connection.

Abstract: A hydrostatic torque converter has a hydrostatic transmission and a stepped or gear transmission shiftable under load by selective actuation of respective clutches assigned to the gear trains. The variable-displacement pump is controlled hydrostatically to follow the switchover between clutches with the control pressure to the servocontrolling the displacement of the pump being regulated in response to the fluid pressures of the clutches through respective pressure modulation valves. As a consequence, the hydrostatic transmission compensates for the jump resulting from the shifting of the steps of the gear transmission and follows the stepping of the gear transmission outside the forced actuation of the transmission (positive switching overlap of the shifting clutches) in dependence upon the progress of load transfer from the released to the engaged clutch.
