Abstract: An information preservation and conveyance system for providing information and effects to intelligent creatures in the future. The system provides durable containers with components secured inside and durable structure components, such as building bricks for example, mountable to a durable building, pyramid, or other structure, with at least one structure component having external surface information readable by a human. Higher density durable information providing components may be secured inside a durable container by resilient devices to absorb impact forces. Durable optical magnifier pictographic instructions and an optical magnifier or projector may be secured by durable containers, which can have a container opener durably mounted to exposed sections on the durable containers. The durable containers can contain audio generation apparatus, which optionally may teach a language, and any of a wide variety of types of information and articles of possible interest and value to a discoverer in the future.

Abstract: A revolving air lock controls the flow of air, and the passage of contaminants that may be entrained in the air, between two separate areas. The air lock comprises a base, a vertical shaft rotatably connected to the base at one end, and a bearing support apparatus to which the other end of the shaft is rotatably connected. At least two arcuate walls, having an axis generally coaxial with the axis of the shaft, are located generally concentric to and spaced apart from the shaft. The walls are configured to define at least two segments whereby entrance and exit to the air lock may be obtained. Each wall is connected to the bearing support apparatus and to the base with at least one of the walls having at least one aperture therethrough. A panel assembly comprises a plurality of panels with the inner edge of each panel connected to the shaft, such that each panel extends generally radially outwardly therefrom.
