Abstract: A system for facilitating the practicing or playing of golf may include, alone or in combination, a golf target subsystem, a detection subsystem, and a golf ball dispensing subsystem. The golf ball dispensing subsystem comprises a free standing device placed at the teeing area which may be configured to provide various functions, such as, for example, receiving and storing a quantity of golf balls, exposing non-illuminated golf balls to an illuminating source contained therein, and thereby illuminating the golf balls, and/or dispensing the illuminated golf balls to the golfer. The golf target subsystem is suitably configured to permit a golfer to locate and identify the target area while addressing the golf ball so that the golfer may attempt to land the golf ball within the target area. In addition, to facilitate the identification of the target during nighttime conditions, i.e., conditions without external lighting, the golf target is preferably illuminated.

Abstract: A ferritic stainless steel characterized by superior crevice and intergranular corrosion resistance. The steel consists essentially of, by weight, up to 0.08% carbon, up to 0.06% nitrogen, from 25.00 to 35.00% chromium, from 3.60 to 5.60% molybdenum, up to 2.00% manganese, up to 2.00% nickel, up to 2.00% silicon, up to 0.5% aluminum, up to 2.00% of elements from the group consisting of titanium, zirconium and columbium, balance essentially iron. The sum of carbon plus nitrogen is in excess of 0.0275%. Titanium, zirconium and columbium, are in accordance with the following equation:%Ti/6+%Zr/7+%Cb/8.gtoreq.

Abstract: An improved process for hot working of dispersion-strengthened mechanically alloyed aluminum is provided based on a disclosed unconventional response of such material to thermomechanical processing. The process permits optimization of strength and workability and the production of aluminum alloys of very high strength.

Abstract: An improved dispersion strengthened aluminum-base alloy and an improved method for producing the alloy are provided. A preferred alloy comprises, by weight, about 3 to 5% Mg, about 0.2-2.5% C, and about 0.3 to 4% O and the balance essentially aluminum.
