  • Patent number: 4699337
    Abstract: A variety (FIG. 4) of aero engines (30) can be rear-loaded into an aircraft cargo bay (10) with precision and safety and minimal clearance with the sides of the bay (10) by installing a roller conveyor trackway (20,22) along two seat rails (12,14) running the length of the bay (10) and its bottom-hinged rear-loading ramp (15). A ground trailer (33) carrying the engine (30) on its yoke (31) is coupled to a dolly (37) running on the trackway (20,22) and the yoke (31) transferred from rails (32) on the trailer (33) to rails (36) on the dolly (37). The dolly (37) is then winched (27) along the trackway into the bay (10) where it is made secure for flight of the aircraft. The dolly (37) can be dismantled when not in use and the trackway (when installed) is useful when pallets are to be transported.

  • Patent number: 4270938
    Abstract: In a process for decontaminating a nuclear process off-gas stream, oxygen and oxides of nitrogen are removed by catalytic reaction with hydrogen. The feed gas stream is then passed serially through a drier, a carbon dioxide adsorber and a xenon adsorber to sequentially remove water, CO.sub.2 and xenon therefrom. The feed gas exiting the xenon adsorber is passed to a krypton recovery process wherein krypton is concentrated to a first level in a primary distillation column, partially evaporated to increase concentration thereof and is brought to a concentration of approximately 90 mol % or greater in a second distillation column thereby enabling efficient storage of a radioactive krypton product. The xenon gas removed from the main feed stream in the xenon adsorber is passed to a freezeout heat exchange device to concentrate xenon to approximately 99% or greater, balance krypton.
