    Abstract: This invention is an improvement on my U.S. Pat. No. 3,000,766 and is directed to the recovery of metal values in scrap materials by separating the metal values from any nonmetallic material associated therewith, such as insulation on wires or other electrical equipment. The improvement resides in carrying out the removal of unwanted nonmetallic materials in two separate stages, the second of which is similar to that described in U.S. Pat. No. 3,000,766, but is carried out much more efficiently because of the treatment which prepares the scrap for this step. In the first stage, a substantial amount of the nonmetallic material is removed by either burning or immersion in a nonoxidizing fused salt melt.

    Abstract: The preparation of phosphors such as those based on zinc sulfide and/or cadmium sulfide in the form of very fine particles which include not only the sulfide but also the activator and mineralizer required to make this an active material and the deposition of such an active material from a clear solution containing the phosphor, mineralizer and dopant necessary to complete an active material, into the pores of a suitable substrate, thereby producing the essential element for a high resolution information retrieval transducer.

    Abstract: The impregnation of an anodized layer on aluminum with silver salts is greatly improved and facilitated by supplying the soluble silver salt (used as the means for eventual formation of silver halide in the pores of the anodized aluminum) as a solution in which the solvent is a combination of a minor amount of water and a major amount of highly polar organic liquids in which alkali chlorides show low or very limited solubility. By use of this improved technique, a shelf stable photosensitive article is obtained which is capable of yielding deep, lustrous blacks on exposure and development without the need for gold toning to obtain such a result.
