Abstract: Thermal suppressors and techniques for the use thereof are utilized to reduce the thermal signature of an object having a temperature greater than its environment. Multi-layers of low emissivity materials separated by air spaces are used to minimize heat transfer by radiation. This design, coupled with a technique for inducing air flow through the spaces between the various layers for cooling the outer surface of the suppressor, effectively reduces the temperature of and thus the thermal signature of the object. Air entrainment means attached to the object may be used in conjunction with the multi-layered suppressor to further aid in collecting, funneling and expelling heat emanating therefrom. Means for dissipating solar energy are also incorporated into the suppressor.

Abstract: Disclosed is a method for making camouflage from sheets of multi-colored coated fabric. The coated fabric is formed by sandwiching the base fabric between two films of fused polyvinyl chloride film; the two films are tightly bonded to the base fabric. Each film is formed by applying the different - colored plastisols to preselected portions of a carrier web, and then overcoating these colored portions of the web and any uncoated portions of the web with a plastisol of another color. After each of the two multi-colored films is created, they are bonded to the base fabric while the films are still attached to the carrier web; then each carrier web is stripped from the outsides of the finished multi-colored, coated fabric. These multi-colored coated fabrics are cut into sheets which are attached to a net to make the camouflage screen.

Abstract: This invention comprehends a machine for producing camouflage nets. Different camouflage garnish patterns are secured to a net in a preselected and predetermined manner on a repetitive basis. Also, comprehended is a method of making a camouflage net by providing different shape camouflage garnish pieces that are applied to a net at predesignated work stations.

Abstract: When manufacturing camouflage sheets of substantial size, the camouflage pattern is normally printed or punched in repetitive consecutive steps so that a pattern repeat may be seen and impairs the camouflaging effect. The invention makes it possible to considerably increase the pattern repeat, i.e., the distance after which the pattern repeats itself on the sheet without increasing the size of the pattern, in that the sheet and the tool such as a printing plate are angularly displaced relative to one another in their own plane so that the pattern is repeated a number of times on the sheet such that adjacent areas of pattern are angularly displaced (turned) relative to one another. Thus, the pattern of each such area is in another angular position than the identical preceding pattern and the identical subsequent pattern.
