Abstract: The train of containers is intended for a plant for pneumatic transportation of goods through a tube, wherein the containers are interconnected by means of spherical joints.On the end face of the leading or foremost container in the direction of the travel of the train there is mounted a front flap spanning the lower half of the gap between the container and the tube, whereas the end face of the trailing or tailmost container carries thereon a tail flap spanning the upper half of the same gap, the lateral sides of each container having mounted thereon side flaps acting as plain bearings and being adapted to travel along guideways mounted on the internal side wall of the tube.

Abstract: An assembling and repair station wherein the trough adapted to receive the containers is mounted on guideways extending perpendicularly to the center line of this trough. A plurality of troughs is arranged at both sides of the guideways, to accommodate the containers in the course of repair work. The troughs are arranged so that their center lines are parallel with the center line of the container-receiving trough and aligned coaxially therewith, when the container-receiving trough is brought into opposition to either one of the plurality of the container-accommodating troughs. The container-receiving trough is connected via a switch by one end thereof with a main pipeline, its other end being connected with a container-arresting device, the trough carrying a device for advancing a container therealong. The disclosed structure of the assembling and repair station increases its capacity.
