Abstract: Disclosed is a soldering iron comprising at least one replaceable soldering tip and a tip holder which supports the same and is provided with a handle section and a terminal housing section that adjoins the tip holder. In order to be able to remove a soldering tip from the remainder of the soldering iron in a simple structural manner without using additional tools, the tip holder (3), along with the soldering tip (2), is embodied as a detachable module (5) which can be removably connected to the terminal housing section (4).

Abstract: In a temperature regulator for soldering and unsoldering equipment having a heating device fed by a controllable electric source of heating current, the heating output of which is transmitted to a spot to be soldered by a heating output transmission device, a signal that is proportional to the temperature of the heating device is generated and compared in a comparator of a control circuit to a set value. The control circuit derives from the output signal of the comparator a control signal for controlling the source of heating current. In addition, a temperature sensor (5) is arranged in the area adjacent to the spot to be soldered of the heating output transmission device (3), the output signal of which is compared in another comparator (23) of another control circuit (23, 27, 28) to another set value (7). The second control circuit supplies another control signal for controlling the source (11) of heating current.

Abstract: For improving the load-change behavior of a motor vehicle when driving through a curve, the motor vehicle is provided with a lockable differential continuously activatable in its locking action. The activation of the locking differential takes place in the first instance in two steps dependent on power output, whereby a velocity-dependent characteristic may be superimposed additionally on this power output-dependent control.

Abstract: A transport vehicle which includes a vehicle frame, a vehicle cab or cabin, and a spring support arrangement for supporting the vehicle cab or cabin at the vehicle frame. At least one of a mechanical or hydraulic elevating system is operatively connected at the vehicle cab or cabin and the vehicle frame for enabling a predetermined amount of pivotal movement of the vehicle cab or cabin relative to the vehicle frame in a vertically extending plane. A damping system is operatively connected to the elevating system so as to effect a damping action thereon.
