Abstract: Apparatus for engaging interlocking apertures provided on the bottom of intermodal cargo containers to permit vertical stacking of the containers. The apparatus is in the form of integrated interbox connectors movably connected to the containers and positionable between in a stored position situated within the walls of the container and a connecting position situated on top of the roof of the container to engage the interlocking apertures of a vertically adjacent container. A pin is provided for securing the interbox connectors situated in the connecting position to said interlocking apertures provided on the bottom of said vertically adjacent container.

Abstract: A system for the transmission of digital data elements corresponding to at least one application each comprising at least one stream of data elements, the data elements being constituted by digital elements distributed in the time-frequency space and transmitted in the form of symbols constituted by a multiplex of orthogonal carrier frequencies modulated by a set of the digital elements and broadcast simultaneously, the symbols being organized in successive frames, each frame being organized in at least one data conveying channel, each channel being constituted by a succession of at least one consecutive symbol. The data elements may advantageously be transmitted, in each channel, either in transparent mode or in packet mode.

Abstract: A rotary drive cutter for use on the rodway surface reclaiming machines is disclosed which includes spiral flighting fixed to an axially rotatable drum, the flighting includes a plurality of regularly spaced recesses for receiving tool holders each being removably mounted within the flighting recess such that an edge of the tool holder projects laterally outward beyond the side of the flighting a distance sufficient to protect the flighting section from abrasion and thereby extend the life thereof.
