Abstract: A module for the storage of nuclear waste packages from a nuclear power plant. The module includes a concrete precast container (12) with sidewalls (16) and a bottom (17), a concrete precast lid (14) removably disposed on upper edges of the sidewalls (16) to close the container (12), and a cylindrical one-piece seamless liner (22) abutting and covering the interior surface of the container (12). The liner (22) is provided with a plurality of ribs (32) formed integral with the liner (22) that extend along outside surfaces of the liner sidewalls (28) and bottom wall (30), and the ribs (32) are embedded within the concrete precast sidewalls (16) on the container (12). The plurality of ribs (32) can be T-­shaped or dovetail shaped in cross-sectional area and may extend either longitudinally or circumferentially about the liner (22). The module is manufactured by first forming a one-piece seamless liner (22) including the ribs (32, 34) on its outer surfaces, placing the liner (22) in a mold for the module and thereafter pouring concrete into the module mold to completely fill the space between the liner (22) and the mold for embedding the ribs (32, 34) within the concrete. The integrally formed liner (22) is advantageously devoid of seams or weld joints and provides an additional barrier for nuclear wastes.

Abstract: A depository apparatus includes a common entry slot (14) for receiving both envelopes and single sheets, such as cheques, and thickness sensing means (216) for providing an output indicative of whether a deposit item is an envelope or a sheet. Transport means (38) transports deposit items along a common feed path to a printer (42) for printing data on envelopes and sheets, and to a read head (40) for reading data from sheets. Sheet alignment means are included in the common feed path and are operable to bring about alignment of a sheet relative to the read head (40) by moving the sheet into engagement with reference means (170). Operation of the transport means (38) is interrupted during operation of the alignment means. Envelopes are fed directly into a first container (146). After reading of data from a sheet, operation of the transport means (38) is reversed to feed the sheet into a selected one of two further containers (138, 140).

Abstract: The levitation device for suspending an object without contact under the influence of gravity without contact with a solid surface is characterized by the combination of a gas levitator which directs a concentrated flow of gas along an axis upwardly to lift a majority of the weight of the specimen, and an acoustic device which exerts an acoustic positioning force on the object to restrain movement of the specimen away from said axis. Using gas flow to provide upwards lift decreases the degree of acoustic force required to hold the object in a given position. The problems of generating and dealing with sound at very high pressure levels are greatly reduced. Medium to high density objects are levitated in the earth's gravity without the problems and limitations associated with the use of single prior methods alone. Also, stable gas levitation of liquids is accomplished, which has been very difficult or impossible to achieve in the past.
