Fabrication of Pd-Cr wire

Fabrication of Pd-13 percent Cr alloy wires is described. Melting, casting, swaging and annealing processes are discussed. Drawing to reach two diameters (0.003 inch and 0.00176 inch) of wire is described. Representative micrographs of the Pd-Cr alloy at selected stages during wire fabrication are included. The resistance of the wire was somewhat lower, by about 15 to 20 percent, than comparable wire of other alloys used for strain gages

Copyright Problems of the Phonograph Record Industry

This article addresses itself to several difficult questions. Are phonograph records copyrightable? What is the scope of a copyright owner\u27s mechanical reproduction right, and how exclusive is this right? What protection against infringement of the recorded performance, as opposed to the musical composition incorporated in it, has the record manufacturer? What additional statutory protection might be granted in this area, and what of its constitutionality
