    • For a shut-off device comprising a tubular housing to be built into a pipe and a rotary valve for which a driving shaft penetrating the housing and a seat in the housing are provided, a ring wheel (4) with movable bearings (9) being disposed on the driving shaft (10) and the valve flap (3) being guided in the ring wheel (4) and connected with the driving shaft by a gearing (22, 23) which locks when the valve flap (3) swivels in and serves to press the valve flap (3) onto its seat (32), the invention provides for the following: when the driving shaft (10) is rotated back, the gearing (22, 23) lifts the valve flap (3) axially off the seat (32) until the valve flap (3) is supported on the ring wheel (4), and the gearing (22, 23) constitutes the connection between the valve flap (3) and the driving shaft, the valve flap (3) being supported on the ring wheel (4).

    • The invention concerns an arrangement for cooling an electric cable which comprises deep-cooled inner and outer conductors at high voltage and zero potential, respectively, and is provided with cable terminations, in which said inner and outer conductors are connected with respective inner and outer ordinary conductors. The invention consists of the provision that separate cooling loops with a common coolant supply unit are associated with the inner and outer ordinary conductors, and that likewise separate cooling loops with a common return and a further common coolant supply unit are associated with the inner and outer conductors. In this arrangement, the heat losses produced can be removed to the coolant supply units with relatively high efficiency.
