Abstract: A container having a mechanism for locking a pressing member comprises a toothed segment mounted in the body in a plane parallel to the intermediate wall and capable of limited movement in the plane of the wall in mutually perpendicular directions, for which purpose it is connected via a system of pivotally interconnected levers to the cover and via a tie with an axle secured to the intermediate wall, the axle mounting a lever with a toothed member for engaging the toothed segment in the course of transportation of goods and having a through slot near the toothed member for accommodating a roller mounted on the pressing member in such a manner that the geometrical axis of the roller is parallel to the axes of the journals of the pressing member. Mounted in the intermediate wall parallel to the slot for the journals of the pressing member is an additional through slot accommodating the roller and a horizontal slot accommodating the axle of a pivot interconnecting adjacent levers.

Abstract: A gate comprising a body (1) hermetically connected to inlet and outlet branch pipes (2,3) that are arranged coaxially relative to each other and connected to the pipe-line of the pneumatic conveyer. The body (1) accommodates a branch pipe (4) having a cross-section corresponding to the cross-sections of the inlet (2) and outlet (3) branch pipe and kinematically connected to a drive (5) turning it. Rigidly secured to the outer wall of the branch pipe (4) disposed in the body (1) is a damper (6) used to overlap one of the branch pipes (2) connected to the body (1). The damper (6) mounts a ring-like member (7) made from a resilient material. The shape of the member (7) corresponds to the cross-section of the inlet branch pipe (2) to be overlapped. The branch pipe (4) is mounted in the body (1) so that it can swing to a certain extent in a plane perpendicular to the plane of the damper (6) and relative to an axis (8) passing below the longitudinal axis (9) of the inlet (2) and outlet (3) branch pipes.
