Apparatus to screw heavy lids very sensitively on thick-walled receptacles n order to avoid damaging the threads includes a stationary member centered on the receptacle and of an axially movable platform which is guided such that torques can be transmitted and the common axis always remains the same. Resilient members of adjustable length transmit mass forces in vertical direction exactly on the stationary member and prevent additional forces from acting on the flanks of the threads.

Apparatus for screw-coupling two heavy weight components having a common

The invention is directed to a double-container unit for transporting and oring radioactive waste such as irradiated nuclear reactor materials. The double-container unit includes an outer shielding container and an inner storage container made of steel for the gas-tight inclusion of the radioactive materials to be stored. The outer shielding container provides the required shielding and mechanical security during handling and transport of the unit. In order to simplify the assembly and manipulation of such a double-container unit, an intermediate ring is seated in the loading opening of the shielding container and is joinable with this container. A shielding cover is attachable to the intermediate ring for closing the shielding container.
