Abstract: Systems and methods directed to the purchase of articles formed of precious metals are disclosed. Precious metal content is analyzed using an x-ray fluorescence (“XRF”) analysis instrument to determine alloy content, in combination with an ultrasound or electrical conductivity instrument to confirm uniformity of cross-sectional content. The present method thus advances the art of precious metals transactions by precisely analyzing and determining precious metal content and purity, and combining said data with real-time pricing and a digital record of the transaction including the identity of the seller. An automated system is disclosed for fully automating the purchasing of article of precious metals.

Abstract: This apparatus is for evaluation installed cable systems, including those that are already in use. The apparatus measures dissipation factor, partial discharge (corona) and insulation resistance of the cable system; all of these being necessary to determine the condition of the cables. This invention is unique, in that it can be used with installed cable systems that have their metallic shielding grounded; and the apparatus can be mounted on a truck or trailer for movement to any place where an installed system is to be evaluated.
