Abstract: The invention relates to a device for depolymerizing used and waste plastics, comprising a closed reactor and a circulation system the mildly heating of the reactor contents connected to the reactor, as well as to a process for depolymerizing used and waste plastics. To protect the circulation system from erosion by solid particles contained in the reactor contents, the reactor is designed so that the reactor contents drawn off into the circulation system traverse a riser section integrated into the reactor for removing fairly coarse solid particles having correspondingly high settling rate before entry into the take-off line.

Abstract: An ammunition magazine for stowing large-caliber ammunition in a miltiary tank. The rack has an intake rack comprising rows of essentially horizontal intake tubes positioned one above and next to another for accommodating shells. The rack can be lowered into the tank's ammunition bunker from above. The intake rack is suspended at the top from an antivibration and shock-absorbing suspension on the bottom of an impact-resistant roofing plate that fits into an opening in the roof of the tank and can be locked into the opening along the edge. The rack has at least one centering pin at the bottom that fits into a receptacle on a base secured to the floor of the ammunition bunker when the rack is lowered in.
