Abstract: The subject of the invention is a safety system for vehicles making possible, that in case of tipping over or tilting of vehicles, the system senses the substantial shift of the vehicle from the basic position, puts back the vehicle automatically to its original position, or from a horizontal position into a partially standing position, ensuring that passengers stuck into the vehicle can be freed. The safety system for vehicles according to the invention consists of a sensor unit monitoring the position of the vehicle and a lifting unit (2) controlled by the sensor unit, as well as a lifting structure (3) placed in the lifting unit (2), and the lifting unit (2) including the lifting structure (3) is placed on the upper part of the vehicle (1), preferably on the top of it, in given case it is fixed to its upper frame, and it is controlled by the sensor unit placed inside the vehicle (1).

Abstract: A switch, preferably for switching medium voltages, includes a structure which creates a gas-blast to quench an arc drawn between two separating contact pieces of the switch. The gas-blast is created solely by the quenching gas which is heated by the arc, without auxiliary pressure creating mechanisms. The gas blast is sufficiently powerful to cut off high and low currents without use of pressure-controlling valves. The result is realized via a flow-off pipe located between a space where the arc develops and a gas exhaust space. One end of the flow-off pipe opens into the exhaust space. The size of the flow-off pipe is determined in part by the speed of propagation of a pressure wave which is formed in the arc space during the heating phase of the arc and the length thereof is deliberately selected such that the pressure gradient between the heated quenching gas and the arc space is maximized.

Abstract: The gas-blast circuit breaker preferably provided for switching medium voltage has a housing (1) filled with insulating gas. In this housing (1), two contact members (7, 8) are arranged which can be moved relative to each other along an axis (6), and a fixed (8) one of which is formed of two half-shells (11, 12) spaced apart from each other along a plane of separation (16). A power terminal (5), arranged transversely to the axis (6), is electrically conductively connected to the fixed contact member (8). This circuit breaker is to be simplified while retaining a reliable current transfer from the power terminal (5) to the fixed contact member (8).

Abstract: Superconductive cables are disclosed including wires containing filaments of a superconductive material embedded in a matrix material which is normally conductive at low temperature. Undesirable inductive currents are created within the matrix material which partially flow along the filaments due to flucuations or changes in the magnetic field or due to variations in an external magnetic field. In order to suppress such undesirable currents and the losses connected therewith, the wires are twisted and cabled to form twisted strands of wires. The strands of wires are additionally twisted or entwined into bundles of twisted wire strands. This additional measure permits a systematic transposition of the wires and thus a suppression of the interference currents heretofore unattainable. In a preferred embodiment of the disclosed superconductive cable, the conductor wire strands are twisted or entwined with cooling pipes which permit an even cooling of the cable across its entire cross section.

Abstract: A superconductor structure is disclosed in which a plurality of superconductive assemblies are provided with at least one cooling arrangement. The superconductive assemblies consist of superconductor components and a stabilizing conductor, with at least a portion of the stabilizing conductors in the structure being provided with cooling passages. A cooling arrangement is enclosed between adjacent superconductive assemblies. The assemblies are preferably insulated from each other to prevent eddy current flow and may be joined by resistors or diodes connected across the ends of the superconductor components.

Abstract: An electrical superconductor comprises in a stepwise manner single conductors and at least two stages of stranding of component cables and interstitial layers having a high resistance relative to the conductivity of the matrix material arranged between the single conductors and/or the component cables. The electrical resistance of the interstitial layers from inner twisted single conductors to the interstitial layers of the outer component cables are made progressively higher in at least two consecutive interstitial layers in order to effect a reduction in electrical losses in an economical manner.
