Translation of "Auffahren auf" in English

Thus, it is possible to drive the rotor onto the envelope flap in a trouble-free manner.

This reduces noise and increases comfort when the vehicle is driven on to the lift.

Entering to a motorway, some drivers stop even on the acceleration-lane.

The rim disks of the rollers enable a run-up onto the ramp member and a relief of the running surface.

The engagement of the switching vane with the floor switch roller produces unpleasant noises in the elevator car.

With its optimized weight distribution this machine is especially well suited for driving onto snow!

Safety edge makes the gate stop and reverse on contact with an obstacle.

When entering the transfer station 74 a, the skid 12 can bypass the rotary disc 108 on the inside.

In this manner, one is able to avoid running up too closely to the vehicle in the adjacent lane.

In order to do this, it coordinates the entry of snow gear onto the runway with air traffic control.

The directive also contains provisions on "underrun protection", primarily concerning commercial vehicles, in order to limit damage should a motor vehicle crash into the back of a commercial vehicle.

Since the number of road accidents during the night which result from running of a vehicle into the rear of the other vehicle is high, many manufacturers of road vehicles try to prevent this by means of introduction of visual warning devices whose light is more intense, or which reflect the light more intensely, or have larger surfaces.

On the other hand, the device according to the invention renders it impossible to assume the lights belonging to one vehicle as the lights placed on two different vehicles and prevents running into a parked vehicle, especially if a warning reflex triangle is not put up or is overturned by a strong wind.

BACKGROUND OF THE INVENTION The invention relates to a process and apparatus for cleaning a swimming pool, where the apparatus, device, moves back and forth in the swimming pool, and where the device has a gear that can be switched between reverse and forward with driving gears or belt drives during operation; with a contact rail frontally positioned by the cleaning device's casing, as well as a rear positioned switch rail, where correction-dependent signals are supplied to the gear when the device is striking an obstacle via a control mechanism.

According to the invention, to execute the work process, the cleaning device encompasses a gear capable of shifting back and forth between forwards and reverse, and is equipped with driving gears or belts, a contact rail positioned in the front of a casing of the cleaning device, as well as a switch rail positioned at the rear from which, correction dependent signals supply the gear via a control mechanism when the device moves into an obstacle, and is identified by the fact that the driving gears positioned on a drive shaft under the insertion of at least one clutch is connected via a transmission with a prime mover and the clutch with the control mechanism.

BACKGROUND OF THE INVENTION Field of the Invention The present invention refers to a method of bending sheet metal pieces to a predetermined bending angle by means of a bending apparatus having a computer control means and comprising a movable bending bar and a fixed bottom die having a die bottom member, the height position thereof being adjustable in accordance with the bending angle to be achieved.

To permit a convenient travel of vehicles on bridge end sections 2.1, 2.n, all the roadway carriers 4 are provided with integrated ramp components 80 at their ends.

When carrying out a measuring procedure or taking a sample by immersing a probe into a vessel containing a melt to be observed, for instance a steel works converter, the holding means carrying the probe may be bent, because, for example, the probe is driven against stock not yet melted or pushed against slag parts floating on the molten stock.

To prevent abutment on the trailing upper edge of the preceding and already stacked piece of mail, the upper edge of the next following piece of mail 8a is forced and guided against guide sheet 4 by attachment 3a (FIG. 4).

During a movement of the ski head-on into an obstacle or, during skiing, through a depression, where also dangerously high forces can act onto the leg of the skier, the sole plate 19 moves together with the cup 28 and the carriage 3 in a direction toward the tip of the ski (i.e. to the FIG. 9 position).

Since during skiing head-on into an obstacle also always generates one force component in the elevational direction or the lateral direction, a release of the ski shoe is assured.

This structure enables the ski shoe, even during a head-on collision of the ski with an obstacle, to be reliably released.

The external interference force 3.9 arises when the door moves against an obstacle, wherein it is assumed for this example that the safety strips 1.11 and the hall monitor 2.10 are intentionally or unintentionally ineffective.
