Abstract: A steering column for a motor vehicle includes a mounting and a carriage received in a guideway of the mounting for movement between a rearward starting position and a forward end position. Arranged between the carriage and the mounting is an actuatable locking device to lock the starting position of the carriage during normal travel and, when being released, to allow a shift of the carriage to the forward end position together with the steering wheel to thereby facilitate entry of the driver. The locking device has at least one predetermined breaking element dimensioned to either break or to become deformed sufficient to release the locking device and to allow the carriage to move from the starting position to the end position, when an impacting predefined crash force is exceeded in the event of a crash.

Abstract: A cooling installation for a machine tool or the like, having a circulation system in which coolant circulates, wherein the coolant is conducted to a tempering device of the machine tool, wherein a metering unit is assigned to the circulation system, by which an external coolant can be metered to the coolant circulating in the circulation system, and wherein the metering unit can be controlled by a control device. In order to set the best possible constant temperature level at the tempering device, the circulation system has a buffer tank through which the coolant is conducted, and the metering unit meters the external coolant into the return flow coming from the tempering device and into the circulation system upstream of the buffer tank.
