Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
107 words
A flexible camouflage covering adapted for covering objects such as motor vehicles, arms and the like in the presence of snow-covered soils and for impeding visual and photographic observation of said objects, said covering including means for reflecting ultraviolet radiation having a wavelength in the range of 320 to 400 nanometers and maintaining the flexibility of the covering at temperatures as low as -50° C., said means comprising at least a superficial layer of a compound based on a polar polymeric material containing a filler that is stable in a sulphur-containing atmosphere, said filler being selected from the class consisting of titanium salts, silicates and silicon dioxide.
Claim 2
Dependent Claim
107 words
A flexible camouflage covering adapted for covering objects such as motor vehicles, arms and the like in the presence of snow-covered soils and for impeding visual and photographic observation of said objects, said covering including means for reflecting ultraviolet radiation having a wavelength in the range of 320 to 400 nanometers and maintaining the flexibility of the covering at temperatures as low as -50° C., said means comprising at least a superficial layer of a compound based on a polar polymeric material containing a filler that is stable in a sulphur-containing atmosphere, said filler being selected from the class consisting of titanium salts, silicates and silicon dioxide.
Claim 3
Dependent Claim
25 words
A camouflage covering for snowy soils according to claim 1, characterized in that the filler is a mixture of titanium salts, silicates, and silicon dioxide.
Claim 4
Dependent Claim
33 words
A camouflage covering for snowy soils according to claim 2, characterized in that in the mixture of titanium salts, silicates and silicon dioxide there is present also a lead salt of white color.
Claim 5
Dependent Claim
25 words
A camouflage covering for snowy soils according to any one of claims 1, 2, or 3, characterized in that the titanium salt is magnesium titanate.
Claim 6
Dependent Claim
39 words
A camouflage covering for snowy soils according to claim 1, characterized in that the filler is present in a quantity between 20 and 200 parts by weight with respect to 100 parts by weight of the basic polymeric material.
Claim 7
Dependent Claim
48 words
A camouflage covering for snowy soils according to claim 1, characterized in that the polar polymeric material constituting the base of the compound is selected from the class consisting of polychloroprene, chlorosulphonated polyethylene, chlorinated polyethylene, halogenated polybutyl, polyurethane, polyvinyl chloride, epichlorohydrin elastomer, acrylic elastomer, polycarbonate, and silicone elastomer.
Claim 8
Dependent Claim
