Abstract: The arrangement conveys cans which deliver and receive textile material, between machines delivering such material and machines which are substantially of the same type but use such material, along a closed transport or conveying path. The conveying path is of a structure comprising sections which extend parallel to each other including a siphon-shaped stand-by section containing parallel legs. Using such sections there is rendered possible a space-saving arrangement and simultaneously ready accessibility to the different sections of the conveying path and the machines for operating the machines and eliminating faults and malfunctions at the machines and the sections of the conveying path.

Abstract: This describes a method and an apparatus for supplying freshly made concrete. Containers having two compartments are used, one compartment for aggregate and a companion compartment for cement. The container compartments are loaded from the top and are emptied simultaneously or one after another through apertures at the bottom of each compartment opened and closed by manually or power operated gates. The top of the compartments is closed by covers which protect against humidity infiltration or humidity loss. The contents are discharged through the respective aperture onto a receiving conveyor which carries the contents into an adjacent mixer where they are mixed together with the specified amount of water and specified additives which are measured out and introduced by appropriate apparatus mounted on or near the mixer to make the eventual viscous concrete.
