Abstract: A laser marking system for automotive glass having an ink spray device capable of depositing an ink layer upon the glass and a drying system is provided for accelerating the drying of the ink layer. A laser system is also provided to operably heat and bond at least a portion of the ink layer to the glass in a predetermined pattern. A cleansing system removes unbonded portions of the ink layer from the glass and a controller is provided to direct the laser system in the predetermined pattern.

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.
