US Patent 3,799,209 (granted March 26, 1974) to Norris F. Dow and Murray Halton, assigned to Doweave, Inc., describes an improved machine for weaving stable triaxial fabric. Its main feature is a beat-up system of one above beater and one below beater, which together make a single beat-up motion in each fabric formation cycle. The text covers the cam-and-linkage beater controls, the beater paths and rest positions, warp traversal, shed formation, and six claims. Five sheets of patent drawings show the machine in side elevation, sequential stages of the cycle, and a plan view of the triaxial fabric.

US Patent 3,446,251, granted May 27, 1969 to Norris Fitz Dow (assignor to General Electric), describing triaxial woven fabrics made of three sets of yarn courses crossing at about 60 degrees. The text explains how interlocking intersections prevent slippage and give nearly isotropic strength, including bias strength. Fifteen figures show variants differing in porosity, density, paired or floating yarns, twill-like and long-float arrangements. The patent closes with 23 claims and a list of references cited. Seven drawing sheets precede the specification.

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.

US Patent 3,884,429 (granted May 20, 1975) to Norris F. Dow describes a warp beam for triaxial weaving. Warp yarns from a rotating creel are wound helically into a flattened sleeve on a take-up beam, so the yarns migrate across the fabric width and transfer from upper to lower warp sets as the beam is unwound on a triaxial loom. The text covers the background, two beaming apparatus embodiments, the weaving method, and six claims. Four sheets of drawings show the apparatus and a stabilized triaxial fabric.
