Abstract: The superconducting magnetic system comprises a superconducting sectionalized coil. Each section of the coil has a series-connected disconnector with a controlled shunt of superconducting material and normal zone detection unit connected in parallel to the coil section and its disconnector. Said coil is linked inductively with an energy removal device. The latter comprises a heat-insulated compartment cooled to cryogenic temperature. The compartment contains the disconnectors and at least one coil of normal metal and a jumper of superconducting material making up a closed electric circuit. Each controlled shunt and jumper is fitted with a control winding. The control windings of the shunts are linked electrically with the respective normal zone detection unit. The control winding of the jumper is linked electrically with each normal zone detection unit.

Abstract: An arrangement comprises a pipeline filled with liquid at atmospheric pressure. The pipeline serves for displacement of containers with cargo therein by means of driven conveyors arranged along the pipeline. Endless traction members of the conveyors comprise belts having at least one row of equally spaced elements. Each container has at least one longitudinal groove with stops for engagement with the belt elements during the displacement of the containers. The arrangement according to the invention enables transportation of cargoes with comparatively low power consumption.
