Abstract: A headpiece is provided for a transverse flute having a first leg and a second leg, which is connectable to a tube of the transverse flute. The two legs are arranged at an acute angle to one another.

Abstract: The invention relates to a high-temperature superconductor component with a particular cross-sectional area, which has a current-carrying section, the current-carrying section being in contact with a safety conductor in such a way that the critical current flowing on transition of the superconductor to normal conduction can be taken up without damage by the safety conductor in at least 1 second and rerouted, as well as a process for its production.

Abstract: Method for joining parts of ceramic high-temperature superconductor material of the composition Bi.sub.(2+a-b) (Sr.sub.1-c) Ca.sub.c) .sub.(3-a) Pb.sub.b Cu.sub.(2+d) O.sub.x, where a is 0 to 0.3, b is 0 to 0.5, c is 0.1 to 0.9 and d is 0 to 2 and x has a value depending on the state of oxidation of the metals present, the end faces of the parts located at a gap spacing apart from one another are heated by means of a fuel gas/oxygen flame to temperatures from 750.degree. to 875.degree. C. Simultaneously, a rod of the same material above the spacing gap is heated until the melt thereof drips off into the gap between the end faces of the two parts, completely filling the gap. At least the joint region between the two parts is then heat-treated for 7 to 100 hours at temperatures between 780.degree. and 850.degree. C.
