Abstract: A consumable product utilized to maintain and restore hair color comprises a substrate and an effective amount of a directly available amino acid (in pure or diluted form) (obtainable, usually upon digestion or hydrolysis, from peptides, polypeptides, proteins, and derivatives thereof such as acyl and amide forms) wherein the directly available amino acid is selected from the group consisting of tyrosine, phenylalanine and mixtures thereof. Included is a related method for maintaining and restoring hair color that comprises the steps of adding an effective amount of a directly available amino acid selected from the group consisting of tyrosine, phenylalanine and mixtures thereof to a consumable product to produce a supplemented consumable. An efficacious amount of the supplemented consumable may be fed to an animal to maintain and restore hair color in the animal.

Abstract: Apparatus and method for fabricating textured pseudo-single crystal bulk superconducting materials, featuring introduction of a pressure gradient and/or of a magnetic field for enhancement of known melt-texturing directional solidification techniques using a steep temperature gradient furnace for increasing temperatures at which superconductive properties can be maintained in superconducting materials. The strengths of the temperature gradient, pressure gradient and/or magnetic field can be optimally varied, resulting in formation of superconducting material exhibiting superconductive properties at higher temperatures than previously achievable.

Abstract: Methods for the improvement of mechanical properties of aluminum can stock materials. In one method, an aluminum alloy is cast into an ingot, heated at an elevated temperature to homogenize the alloy, hot rolled at an elevated temperature to form hot band material and cold rolled to final gauge. After the heating step, the alloy is hot rolled immediately to minimize the cooling of the alloy between the heating and hot rolling steps.

Abstract: Non-galling, low earing can stock suitable for deep drawing and wall-ironing into can bodies is prepared from continuously cast aluminum alloy strip of an inch or less in thickness. The strip material is heated to a temperature of from 950.degree. to 1150.degree. F. for a time sufficient to homogenize the alloy. The homogenized strip material is cold rolled to effect a first reduction in sheet thickness of at least 25%. The cold rolled sheet is heated to a recovery temperature of up to about 550.degree. F., and subjected to a second cold rolling to effect a reduction in thickness of up to 50%. The cold rolled sheet product is heated to the recrystallization temperature and then subjected to effect a final reduction in thickness of at least 50% of the original thickness of the sheet to impart an H19 temper to the sheet.

Abstract: A high ductility, high strength, moderate conductivity aluminum conductor article and process for making the article are described. The article is a conductor of elongated geometry containing a low volume fraction of intermetallic fibers which are aligned parallel with the major axis of the conductor. The surrounding matrix is aluminum of at least commercial purity to which from 0.5 to 1.5% copper has been added. The fabrication process involves the coupled solidification of eutectic and slightly proeutectic compositions to produce a fibrous microstructure, followed by mechanical working. The ductility of the finished article will exceed about 5%. The final properties may be varied by heat treatments. The broad composition is 1.0-2.0% Co, 0.5-1.5% Cu, balance aluminum.
