Abstract: A process and a precursor composition for preparing a lead-doped bismuth-strontium-calcium-copper oxide superconductor of the formula Bi.sub.a Pb.sub.b Sr.sub.c Ca.sub.d Cu.sub.e O.sub.f wherein a is from about 1.7 to about 1.9, b is from about 0.3 to about 0.45, c is from about 1.6 to about 2.2, d is from about 1.6 to about 2.2, e is from about 2.97 to about 3.2 and f is 10.+-.z by reacting a mixture of Bi.sub.4 Sr.sub.3 Ca.sub.3 Cu.sub.4 O.sub.16.+-.z, an alkaline earth metal cuprate, e.g., Sr.sub.9 Ca.sub.5 Cu.sub.24 O.sub.41, and an alkaline earth metal plumbate, e.g., Ca.sub.2-x Sr.sub.x PbO.sub.4 wherein x is about 0.5, is disclosed.

Abstract: A multiple-function beverage container opener is provided which features an ergonomically-shaped, elongate body having a stay-on tab opener on one end thereof, a crimped-on bottle cap opener on the opposite end thereof, and twist-off bottle opener in a central socket portion thereof. The stay-on tab opener is characterized by an arcuate loop formed between outboard and inboard arcuate-shaped lances. The arcuate-shaped lances and loop are provided with a radius that is substantially similar to the rim of the beverage container lid so that the loop fits between the tab handle and the rim of the beverage container. A ramp is coined in the arcuate loop to further assist in the camming of the tab handle upwardly into the arcuate loop for further pivoting and opening of the scored closure of the stay-on tab opener.
