Abstract: The invention includes superconducting titanium-containing compositions having less than 200 ppm, by weight, of a combined total of interstitial materials selected from the group consisting of nitrogen, oxygen, carbon and hydrogen. The invention also includes methods of forming superconducting titanium-containing superconducting compositions containing less than 100 ppm, by weight, of a combined total of interstitial materials selected from the group consisting of nitrogen, oxygen, carbon and hydrogen.

Abstract: Linear oligomer polychelant compounds and chelates formed therewith have alternating chelant and linker moieties bound together by amide or ester moieties. The compounds have between 3 and 100 chelant moieties, at least one of which complexes a paramagnetic metal ion. The polychelants and especially their paramagnetic metal polychelates are particularly suitable for diagnostic imaging.

Abstract: A method and apparatus are provided for direct casting molten metal to continuous strip of crystalline material by controlling the supply of molten metal to a casting vessel substantially horizontal to an adjacent moving casting roll surface, the molten metal level in the exit end being near the crest of the casting roll, separating a semi-solid cast strip substantially horizontally from near the crest of the casting roll and providing secondary cooling while transporting the separated strip to solidify the strip.

Abstract: There are disclosed polychelant compounds, that is multi-site metal chelating agents, and chelates formed therewith. The polychelants and especially their paramagnetic metal, heavy metal or radioactive metal polychelates are particularly suitable for use in diagnostic imaging, heavy metal detoxification or radiotherapy. The polychelants have a linear or branched oligomeric structure comprising alternating chelant and linker moieties bound together by amide or ester moieties the carbonyl groups whereof being adjacent the chelant moieties, each polychelant comprising at least two said chelant moieties capable of complexing a metal ion.
