  • Patent number: 9610694
    Abstract: Device for handling objects in a glove box comprising a carriage (2) to support the objects to be handled, a base (6) relative to which the carriage (2) can be moved along a horizontal axis (X), means of driving the carriage (2) along the first axis (X), these drive means comprising an electric motor (14) arranged such that its drive shaft is orthogonal to the axis (X) and projects opposite the base (6), a transmission shaft (18) parallel to the motor (14), a rack (22) fixed to the base (6) along the axis (X) and a pinion (24) directly fixed in rotation to the transmission shaft (18) and engaging with the rack (22), a transmission belt (20) mechanically connecting the drive shaft of the motor (14) to the transmission shaft (18), the electric motor (14) being declutchable and the carriage possibly being moved manually along the axis (X).

  • Patent number: 9010385
    Abstract: A system for filling a jar with powdery material, for example for the manufacture of nuclear fuel, including a device for connection between the jar and a material feed system, where the device includes: a stationary connection portion connected to the feed system, a connection portion which moves relative to the stationary connection portion intended to be connected to the container's filling orifice, where the moving connection portion includes in the area of a downstream end a lip seal to achieve a tight connection by contact with the contours of the jar's filling orifice and where the said downstream end is connected to the stationary connection portion by a bellows so as to provide mechanical disengagement between the downstream end of the moving connection portion and the stationary connection portion.

  • Publication number: 20110232111
    Abstract: This can opening machine comprises a lower guide ring to center the top of the single-piece can, comprising a centering chamfered face and an upper stop face. A piston arranged in the tool for cutting out the can lid is pushed downwards by a spring extending low enough to separate the cut out lid from the tool. The lid remains in the can during turning and content emptying operations.
