US Patent 3,874,422, granted April 1, 1975 to Norris F. Dow of N.F. Doweave, Inc., describes triaxially woven fabrics with uniform porosity and isotropic compliancy. Three weaves are described: the "bi-satin", the "double basic", and the "substrate" weave. They are built from three yarn sets (wefts plus 1 o'clock and 11 o'clock warps) crossing at about 60 degrees, and the text covers yarn paths, selvage configurations and ten claims. The fabrics are intended for reinforcing molded or curved articles. The scan includes two certificates of correction dated 1979 and 1983, and drawings of the three weave structures.
