Abstract: An alloy resistant to carburization and high temperature oxidation. The alloy consists essentially of, by weight percent, 27 to 35 chromium, 0 to 7 iron, about 3 to 4.4 aluminum, 0 to 0.4 titanium, 0.2 to 3 niobium, 0.12 to 0.5 carbon, 0 to 0.05 zirconium, 0.002 to 0.05 total cerium and yttrium, 0 to I manganese, 0 to I silicon, 0 to 0.5 calcium plus magnesium, 0 to 0.1 boron and balance nickel plus incidental impurities.

Abstract: There is provided a nickel-base alloy with service enhanced strengthening properties. When exposed to ethylene pyrolysis conditions, namely a carbon containing environment and at temperatures of at least about 900.degree. C., the alloy forms M.sub.6 C and MC carbides that strengthen the alloy. The alloy may be formed into internally finned tubing.The alloy includes about 0.08-0.11% carbon, 41-45% nickel, 23-26% chromium, 0.6-0.95% manganese, 1-1.7% silicon, 0.2-0.6% titanium, 0.25-0.55% aluminum, 1.3-1.7% molybdenum, 0.25-0.6% niobium, 0.15-0.45% tantalum, 0-0.2% tungsten, 0.001-0.005% boron, 0.01-0.03% zirconium, and the balance iron with trace commercial impurities.

Abstract: A nickel-base alloy having characteristics midway between selected stainless steels and INCONEL.RTM. alloy 625LCF.RTM.. Flexible and particularly useful for exhaust system bellows, wires and braids, the alloy includes about 24-42% nickel, about 18-28% chromium, 1.5-6% molybdenum, 0.2-1 % titanium, up to 1% aluminum, the balance iron, and up to about 1.4% silicon. The alloy demonstrates a novel characteristic of becoming stronger and more ductile during contemplated service temperatures of about 800.degree.-1400.degree. F. (427.degree. C.-760.degree. C.).

Abstract: The inventive method is a method for synchronizing computerized video images with an audio output. The audio output may be in the form of an audio track stored on a compact disk. The synchronization method uses a timing index which corresponds to the audio track on the compact disk. The computer repeatedly reads the audio timing index and compares it to a data table of known video timing codes. Each time the compact disk timing index is read and determined to be greater than or equal to the current value from the data table the next video image is shown.
