  • Magnetic actuator device
    Patent number: 7717396
    Abstract: The magnetic actuator device of the invention comprises a magnetic field generator external to the duct and a permanent magnetic field generator internal to the duct, separated from the magnetic field generator external to the duct by a non-magnetic separator wall, and connected to a moving member, the permanent magnetic field generator internal to the duct being dimensioned to have a face spaced apart from the separator wall so as to define a space that can receive particles of metal without the actuator device jamming.

  • Device for screwing on caps
    Patent number: 6840138
    Abstract: The device for screwing on a cap comprises a gripping head fixed to a rotary spindle, and a drive shaft connected to a drive member carried by a frame, the rotary spindle and the drive shaft are connected to each other on the same axis by a resilient coupling member, connected both to the rotary spindle and to the drive shaft, and the device further comprises a detector member for detecting relative rotation between the rotary spindle and the drive shaft, and a control member for interrupting tightening of the cap when the relative rotation reaches a predetermined threshold.
