Items:
a. “Superconductive” “composite” conductors containing one or more niobium-titanium 'filaments', having all of the following:
a.1. Embedded in a “matrix” other than a copper or copper-based mixed “matrix”; and
a.2. Having a cross-section area less than 0.28 × 10−4 mm 2 (6 µm in diameter for circular 'filaments');
b. “Superconductive” “composite” conductors consisting of one or more “superconductive” 'filaments' other than niobium-titanium, having all of the following:
b.1. A “critical temperature” at zero magnetic induction exceeding 9.85 K (−263.31 °C); and
b.2. Remaining in the “superconductive” state at a temperature of 4.2 K (−268.96 °C) when exposed to a magnetic field oriented in any direction perpendicular to the longitudinal axis of conductor and corresponding to a magnetic induction of 12 T with critical current density exceeding 1750 A/mm 2 on overall cross-section of the conductor.
c. “Superconductive” “composite” conductors consisting of one or more “superconductive” 'filaments' which remain “superconductive” above 115 K (−158.16 °C).
Technical Note:
For the purposes of 1C005, 'filaments' may be in wire, cylinder, film, tape or ribbon form.
