  • Patent number: 6560946
    Abstract: The present invention relates to a distributor that enables covers to be fitted automatically on containers in a chamber without requiring assistance from an operator. It mainly comprises a slider (5) mounted to slide between two plates (3 and 4). The queued covers (2D) are positioned on a lowering and introducing system (11) equipped with three double-fingers (20) that enable the last bottom cover to be selected in each cycle in order for it to drop onto the slider (5). A carrier cell (7) in said slider is used to displace the selected cover towards a positioning cell (9) of the lower plate (4) and drop it onto a container that has been previously introduced by said cell.

  • Patent number: 6048419
    Abstract: The present invention relates to a compacting process suitable particularly for the compacting of materials with a pyrophoric tendency and especially for the compacting of scrap metal generated in the nuclear industry; and compacting means (4), and a compacting device including said means (4), appropriate for the implementation of said process. In said process the blanketed materials are compacted with optimized complementary external blanketing. The inert gas used for said external blanketing is characteristically conveyed via the compacting means (4) and blown in through their lower end (15).

  • Patent number: 5633423
    Abstract: According to the invention, a consumable anode constituted by a metal alloy incorporates between 20 and 70 wt. % iron, between 20 and 40 wt. % cobalt and between 5 and 30 wt. % aluminium. To these basic constituents can optionally be added elements such as nickel and/or titanium and/or copper and/or niobium. The decontamination process involves an electrodissolution of said anode.
