Abstract: A hydraulic press for compacting drums containing radio-active waste. The press consists essentially of a press table, a set of vertical support pillars connected at the top to a hydraulic cylinder with a ram mounted therein, and of a pressure jacket hydraulically movable in the vertical direction between the ram and the press table along the support pillars. According to the invention, the lower end of the ram is provided with an annular chamber in which the pressure jacket is receivable in a retracted position.

Abstract: A rim forming apparatus, substantially comprising a frame having two superimposed drivable and substantially vertically slidable spindles for applying thereon rim forming tools or rolls, the lower spindle being movable by means of a hydraulic cylinder relative to the upper spindle, while the upper spindle is tiltable in the plane through the two spindles for compensating the deflection of the two spindles during the rim forming process, wherein the spindles carrying the rim forming rolls are each received in the one end of a swivelling arm the other end of which is mounted in the frame.
