    摘要： A circuit arrangement for overvoltage protection of a power transistor for controlling an inductive load includes a first varistor which bridges-over the supply connections. A second varistor is arranged parallel in relation to the switching path of the power transistor and in series with a switching transistor. The switching transistor can be controlled by a voltage divider which is connected to the supply voltage via a Zener diode.

    摘要： A switching device for direct-current applications includes a housing having a first wall and a second wall, a plurality of receiving areas for respective mutually substantially parallel current paths disposed in the housing. Each of the current paths has a respective stationary switching contact element and a respective movable switching contact element, the movable switching element being actuatable into a closed position and into an open position so as to form a respective air break, the respective movable switching contact elements being actuatable simultaneously. The switching device includes a plurality of arc-quenching devices associated with the current paths and disposed next to each other, and at least one magnet. The at least one magnet is configured to generate a magnetic field so as to generate a deflection force on the arcs so as to deflect the respective arcs toward at least one of the respective arc-quenching devices.

    摘要： The lubricator is disposed at the picking end of the picking element return device and has a guide duct for receiving a picking element prior to the next pick. The lubricator has oil mist nozzles which face only those surfaces of the picking element which will rub on the guide teeth in the next pick.Very low-quantity lubrication or lean lubrication is feasiable and soiling of the fabric by lubricant is obviated. The lubrication effect is sufficient to obviate metal abrasion between the picking element and the guide teeth so that soiling of the fabric by abraded metal can be avoided.
