Abstract: The press comprises a frame (1), a feed zone (3) for receiving the waste products, a pressing chamber (9) comprising an inlet opening (10) and an outlet opening (11) which are in opposed relation and disposed coaxially relative to the feed zone (3), and a chamber (14) for discharging the solid phase. The press further comprises an element (15) which is movable transversely relative to the axis of the press chamber (9) between a first position for closing the outlet opening (11) and a second position for opening the outlet opening (11), and an arrangement (20) for applying the movable element against the outlet opening (11) of the pressing chamber.

The press further comprises an element (15) which is transversely movable relative to the axis of the press chamber (9) between a first position for closing the outlet opening (11) and a second position for opening the outlet opening (11), and an arrangement (20) for separating leakages of the liquid phase from the solid phase in the discharge chamber (14).

Abstract: The press comprises a frame (1), a feed zone (3) receiving the waste to be treated, a pressing chamber (9) comprising an intake aperture (10) and an outlet aperture (11) and a chamber (14) for discharging the solid phase. The press also comprises a component (15) movable transversely relative to the axis of the pressing chamber (9) between a first position for closing off the outlet aperture (11) and a second position for opening the outlet aperture (11), comprising jacks (20) for horizontal movement of the movable component in the direction of the axis of the pressing chamber (9) in order to apply the face of the movable component facing the outlet aperture (11) against the outlet aperture during compression of the heterogeneous waste.

Abstract: An apparatus for rotating structures such as large antennas which incorporates a motor for controlling rapid rotation of the structure through a ring gear and a screw jack which is selectively coupled to the ring gear for controlling a slower more exacting rotation of the structure about a common axis.
