Abstract: A long-term storage container including a box-like titanium receptacle having a titanium primary cover and sealed by a seal ring of malleable precious metal clamped between the cover and the receptacle, with titanium/ceramic valves in the cover for use in exhausting air from the receptacle and replacing it with argon gas, with titanium/precious metal back-up plugs sealing the valves after the air has been replaced. A titanium secondary cover is bonded to the receptacle by a titanium weld, reinforces the seal by the primary cover, and has a cuttable integral metal wall for ease of opening, and an inner titanium container is disposed in the receptacle with elongated, resiliently flexible ribs in its walls engaging similar ribs on the adjacent walls to provide cushioning against crushing and shocks.

Abstract: A two wheel trailer comprising a trailer body having a deck and a pair of vertically oriented side portions which mount trunnions carrying the suspension arms of a pair of wheels. Locking mechanisms are actuable to permit downward and inward rotation of the trunnions to locate the wheels beneath the upper deck of the trailer body in a compact, recessed relation. Combined spring and shock absorber devices are carried by the trailer body for engagement with the suspension arms. An elongated towing tongue is telescopable within the trailer body. In a preferred embodiment the trailer body includes two hinged together sections, the rearward section mounting the tail lights being pivotable to underlie and enclose the retracted wheels located within the forward section. The folded sections are designed to fit within the trunk of a typical passenger vehicle.
