  • Patent number: 10636597
    Abstract: A thermal fuse for an electrical circuit is described, with a contact arm by way of which two electrical conductors are electrically conductively connected to each other, wherein the connection of the contact arm to at least one of the two conductors is a soldered joint, which loses its strength when a activation temperature of the fuse is reached. In accordance with this disclosure a permanent magnet is provided, which generates a magnetic force, which lifts the contact arm from at least one of the two conductors as soon as the soldered joint loses its strength.
    Type: Grant

  • Patent number: 10315253
    Abstract: A mold for producing a green compact using powder metallurgy processes has an upper punch and a lower punch which are movable along a common press axis and a die body with a charging chute for receiving powder material. The die body has an upper region in which the upper punch is movably guided along the press axis in the charging chute, and a lower region in which the lower punch is movably guided along the press axis in the charging chute. Two cross slides realize a forming region which determines the lateral outside contour of the green compact, and are arranged on the die body so as to be displaceable in a direction which deviates from the press axis. The two cross slides only move into contact with one another when the two cross slides are arranged in their respective end position.
