Abstract: A method for establishing an electrical contact between a normally conducting contact body and the end section of a superconductor annealed in situ, prior to the anneal in which the corresponding end section of the intermediate conductor product is placed on a form of a heat-resistant material which during the anneal does not react with the elements of the intermediate conductor product; and after the anneal, replacing the form with a contact body of corresponding shape. With the method, diffusion reactions between the elements of the intermediate conductor product and the contact body during the in situ anneal are advantageously prevented.

Abstract: In preparing test specimens for analysis, especially by X-ray fluorescence, the materials to be tested are comminuted and then dissolved in molten phosphates that are molten at elevated temperatures (several hundred degrees Centigrade) but solid at room temperature, and are subsequently cast into the required specimen form.
