  • Publication number: 20200061862
    Abstract: A multi-part long knife (10) is provided for cutting rubberized and non-rubberized steel cord, rubber sheets with or without fiber reinforcement, industrial textiles, steel sheets and non-ferrous metals. The multi-part long knife (10) includes an elongated knife carrier (12), on which at least one elongated blade (16), having a cutting edge (18), is held. The knife carrier (12) has a clamping strip (14), which is guided in a recess (22) of the knife carrier (12) in a clamping direction (K). A receptacle (46) for the blade (16) is formed between the knife carrier (12) and the clamping strip (14), which clamping strip (14) is guided in the recess (22). A first clamping surface (50) is formed on the knife carrier (12) and a second clamping surface (52), opposite the first clamping surface (50), is formed on the clamping strip (14), between which the blade (16) can be clamped.

  • Publication number: 20080186680
    Abstract: A monolithic controller for the generator unit of a motor vehicle, which is fixedly connected to a cooling body. The cooling body preferably is a thermally conductive ceramic substrate, which is additionally provided with electrically conductive connections, preferably copper structures. In unpackaged form, the monolithic controller is fixedly connected to the substrate.

  • Patent number: 6320405
    Abstract: An apparatus for switching loads, based on a starting signal, having a first MOSFET output stage and a second downstream MOSFET output stage, each of the MOSFET output stages being controllable by a logic circuit, with a power supply voltage of the downstream MOSFET output stage being supplied over the first MOSFET output stage. The apparatus includes a line that is adapted to connect each logic circuit of the MOSFET output stages and to provide an input voltage to a logic circuit of the downstream MOSFET output stage. The apparatus also includes a monitoring arrangement, which is activated by the starting signal, that is adapted to monitor the power supply voltage of the downstream MOSFET output stage and prevent activation of the first MOSFET output stage when the power supply voltage is below a predetermined value.

  • Patent number: 6148781
    Abstract: The starting device for starting an internal combustion engine includes a starter motor (12) with a pinion for cranking the internal combustion engine; a voltage source (40) for the starter motor; a starter relay (14) for connecting and disconnecting the voltage source to and from the starter motor and an electronic relay (32) for triggering the starter relay according to control signals from the motor controller (50). The electronic relay (32) is mounted on the starter motor or in the starter relay. The electronic relay (32) includes a power module (34) with a redundancy circuit including two transistors (144', 144") coupled with each other by a logic circuit for preventing starter operation when one of the two transistors is defective.
