  • Publication number: 20080070788
    Abstract: The conductive path of the current-limiting device is made of a strip-shaped super conductor, whereby the structure thereof has a metallic strip, at least one oxidic buffer, a type AB2Cu3Ox super conductive layer and a metal cover layer which is arranged thereon. An intrinsically stable bifilar coil is embodied with said super conductor, and a distance is maintained between adjacent coil windings, wherein a distance maintainer is arranged which is transparent to the coolant.

  • Publication number: 20080012571
    Abstract: With a measuring device (1) for determining a voltage of at least one battery cell (14) in a battery (15), it is provided in order to achieve a precise, highly accurate measurement, that a voltage which is applied to an integration circuit (2) is integrated up and in a first and a second comparator circuit (4, 5) is compared with a first and a second comparator threshold value. The time span between the emission of a first and a second switching value is measured using a measuring and evaluation unit (6). In addition, a reference voltage source (3) is provided in order to specify a reference voltage. Due to the fact that in two integration procedures in sequence, a voltage which comprises the reference voltage and a voltage which comprises the voltage of a battery cell (14) to be determined is integrated up, the unknown voltage of the battery cell (14) can be precisely determined by comparing the two integration procedures.

  • Patent number: 7301119
    Abstract: A process and a system are proposed for short-time arc-welding elements, such as for example metal studs, on to components, such as for example metal sheets, wherein an element in the context of a welding operation is initially raised in relation to the component, a welding arc is formed between the element and the component, and the element is lowered again, the lifting height of the element in relation to the component being detected at least within a time segment between raising and lowering of the element. The initiation of the lowering operation and/or the lowering operation itself is controlled as a factor of the detected lifting height such that a previously specified total welding time is achieved.

  • Publication number: 20070222543
    Abstract: An apparatus for remotely actuating a circuit breaker with two stable positions corresponding to a switch-on position and a switch-off position, has a drive mechanism with an electric motor. The apparatus further has first and second switches for switching the motor on and off, a transmission, a coupling mechanism for mechanically coupling the drive mechanism to the circuit breaker and a lever. The transmission can be positioned in two basic positions, and the lever is capable of being moved from a first end position into a second end position with the aid of the drive mechanism. The drive mechanism is configured such that, in the event of the lever being moved over manually from one end position into the other end position, one of the switches is actuated, with the result that the transmission is moved over from one basic position into the other basic position.

  • Publication number: 20070000917
    Abstract: A heating current used to inductively heat a metallic or magnetic work-piece is generated by an inverter supplied by a supply voltage. The inverter includes four switching elements arranged in an H-bridge circuit having two parallel longitudinal branches and a transverse branch. The switches are controlled so the heating current flows through the transverse branch. The diagonally opposed switching elements are switched from a conductive to a non-conductive state in a temporally staggered manner.
