Abstract: An inflatable floating bridge which can be rolled up or folded up when it is not inflated. The bridge comprises two spaced-apart inflatable air hoses at the sides of the bridge, the inflation of these air hoses by means of pressurized air resulting in the laying out of the bridge. When said hoses have been inflated, and the bridge thus has been rolled out, they constitute the buoyant longitudinal side supporting means of the bridge. Between said hoses there is provided a sheet constituting the bridgeway and having its longitudinal sides fluid-tight joined to one of each hose. On the sheet there are also provided load distributing means and spacing means for the distribution of load and for the spacing-apart of the hoses.

Abstract: A base fabric for a radar defeating camouflage material comprising a knitted fabric knitted from a plurality of strands to form a stretchable, flexible fabric having a plurality of openings therethrough, each of these strands constituting a spun mixture of noncontinuous polymeric fibers and noncontinuous metal or carbon fibers. The fibers can be nylon or polyester. The metal fibers can be stainless steel. The metal or carbon fibers can comprise about 2 - 10 percent by weight of the spun yarn, the fibers having an average diameter between about 0.008 and 0.02 millimeters and an average length between about 50 millimeters and 90 millimeters.
