LOL! I found it though

There's no mention of a dual mono-filament, but looks like Nordost didn't develop it after all. 3M is the holder of the patent. It has the following commercial applications: low-loss UHF/microwave interconnect cable, wireless telephony base station interconnect cable, semiconductor device testing equipment; instrumentation systems, computer networking; data communications, and broadcasting cable.
This is in itself proof that the tech behind the high end Nordost ranges isn't BS, but also means that buyers of Nordost cables with mono-filament tech are being ripped off because there's no way telecommunications companies are being charged the same amount for a meter of cable

EDIT: Actually, I've found the bit about dual mono-filaments:
IBM Technical Disclosure Bulletin Vol. 32, No. 6A, November 1989 at p. 173-174, referred-to in U.S. Pat. No. 5,532,657, discloses a construction of coaxial cable where two individual filaments are spirally wrapped around a single center conductor in counter-directions and at different wrapping rates. The multiple crossings of the filaments are said to provide a stable symmetrical cross-section; and the interstices assure a large fraction of air dielectric in the cable. A similar construction using a twisted pair of filaments spirally wrapped around the center conductor is found in a coaxial cable product made by Temp-flex Inc. of So. Grafton, Mass. This twisted pair spacer is not in continuous contact with the center conductor, and therefore allows more air dielectric to contact the surface of the inner conductor.
I'm struggling to find the patent for the Total Signal Control. I'll probably have to use search terms such as coaxial, cable, shielding, audio, etc...
