  • Publication number: 20210087812
    Abstract: A top track seal is useful for sealing a movement joint between a fluted metal deck and an adjacent wall configuration. The top track seal includes a pre-formed sealing strip adapted to seal the movement joint and a first set of two or more sealing elements for sealing corrugations of the fluted metal deck. The sealing elements are spaced apart in the longitudinal direction of the sealing strip and the distance between two consecutive sealing elements corresponds to the distance between two consecutive corrugations of the metal deck. Each sealing element is moldable and has a predefined geometry. Also, an assembly includes this top track seal. Furthermore, a method is useful for installing a wall configuration to a fluted metal deck with corrugations.

  • Patent number: 10946509
    Abstract: A control method for a hand-held power tool includes measuring a temperature of an electric motor, opening a switchable clutch if the temperature exceeds a first threshold value, and energizing the electric motor when the clutch is open until the temperature falls below a second threshold value. In an embodiment, the electric motor is switched to a current-free mode, i.e., switched off, if the temperature falls below the second threshold value. The second threshold value is preferably less than the first threshold value.
