Abstract: A pressure vessel made of two thin-walled, closed-end tube sections joined at a central hub that encircles the open ends of the two closed-end tube sections, with a plurality of radial bolts attaching the sections together through a dovetail mount on the central hub. The central hub has an O-ring groove in which an O-ring rests, providing a seal between the interior of the pressure vessel and the outside. The inner wall of the central hub may have radially thin and radially thick sections to distribute and minimize weight without sacrificing strength.

Abstract: Methods and apparatuses for loading, removing, accessing, positioning or preserving one or more items in a presence of dry ice are provided. The apparatus includes a tapered container that has a barrier-like structure which can partition the inner volume of the tapered container into an internal product storage volume and a dry icechamber. Each of the regions remain substantially undisturbed during handling, operation, use and transport of the tapered container. Methods for selectively introducing dry ice into the dry ice chamber of the tapered container and engaging the barrier-like structure within the tapered container can be achieved with a novel guiding assembly apparatus. The methods and apparatuses are particularly useful when loading and retrieving one or more items in the presence of dry ice for tapered containers that have single restrictive access openings and/or other characteristics which make access and handling difficult.
