A vacuum cleaner includes a housing, a motor-driven suction fan disposed in the housing, a fan motor and a power supply device configured to provide power supply to the fan motor. The vacuum cleaner also includes both a rechargeable battery and cord reel permanently integrated in the housing such that the vacuum cleaner is configured to be alternately operable in a battery mode and a mains mode.

Vacuum cleaner, especially floor vacuum cleaner

A suction nozzle for a vacuum cleaner that can be connected to a suction pipe and/or a suction tube of the vacuum cleaner includes a nozzle part that can be connected to the suction pipe or the suction tube by means of a tubular connection part. A dust sensor is arranged in the flow path of the vacuum cleaner, the signals thereof being evaluated by a battery-operated electronic control device that can be activated by a low-pressure switch. During operation, said control device controls a display device displaying the dust flow. The control device, the low-pressure switch, the display elements displaying the dust flow, and a battery compartment for receiving the batteries are arranged in a housing formed on the upper side of the tubular connection part. The dust sensor is arranged beneath the housing, inside the upper region of the connection part, in the dust air stream.

In an anti-jackknifing apparatus for a semitrailer rig, upon coupling of a semitrailer to a tractor by insertion of a king pin and a wedge on the trailer into a fifth wheel of the tractor, a pin connected to the wedge traverses a guideway to execute therealong a movement limited and attenuated by double-action hydraulic cylinders connected to hydraulic valve group in turn electrically tied to a control unit. At the guideway, limit switches are provided for setting for each direction of angular motion a predetermined maximum jackknifing angle dependent on vehicle construction. The attenuation of rotary movement between the tractor and the semitrailer is implemented by throttle valves as a function of vehicle speed as measured by a speedometer and as a function of brake pressure as measured by two pressure switches.

The invention relates to an apparatus for preventing jackknifing and for improving the lateral travelling stability under critical road and travelling conditions, in connection with semitrailers, articulated buses or vehicles with a towed vehicle part, which comprises a supporting device interconnecting the two vehicle parts pivotably coupled together by means of a pivot joint and a flow limiting device, which prevents an oversteering and uncontrolled swinging of the rear vehicle part of an articulated vehicle comprising two vehicle parts interconnected by a pivot joint, in order to increase the security against jackknifing and the lateral travelling stability of such vehicles. In addition, an apparatus for articulated vehicles is provided, whose blocking action takes place independently of the driver's reaction and the particular travelling conditions, which does not prevent the extension of the articulated vehicle after blocking has occurred, which has no negative repercussions on the travelling behaviour and in which the momentum for initiating a blocking of the joint is only dependent on a control variable and a measured quantity.
