  • Solenoid valve
    Patent number: 6311951
    Abstract: The invention concerns a solenoid valve for the opening and shutting of a channel (16) for a medium, featuring an electromagnet (11) with a soft iron magnetic core (12) and a coil (13) and an armature actuated by them. According to the invention, it is provided that the channel passes through the ferrite core with its feed opening ending at the front side of the ferrite core, that the armature is configured as a sheet metal armature (14) that, on the side of the exit of the channel, is elastically held against the magnetic force and that features a seal (21), on its side facing the channel, which shuts the channel when the sheet metal armature is pulled down.

  • Device for fitting rivets or control therefor
    Patent number: 5957362
    Abstract: An apparatus for attaching rivets, buttons or the like to textiles or the like, having a plunger which performs the riveting stroke and whose upward and downward movement is controlled by the interaction of the top end of the plunger with a cam plate rotationally driven by an electric motor, the apparatus performing a sequence of attachments upon actuation of a switch or the like, the electric motor (39) running at a fixed preset angular velocity being stopped briefly in the top dead-center position of the plunger (24) by a braking device or the like in order to reduce the cycle frequency of the plunger stroke. To this end, the control unit switches off the drive motor (39) in the top dead-center position of the plunger for a preprogrammed time and switches it on again after the preprogrammed waiting time has expired and actuates a brake in particular during the waiting time.
