    摘要: An aluminum alloy suitable for high temperature applications, such as heavy duty pistons and other internal combustion applications, having the following composition, by weight percent (wt %): Silicon  11.0-14.0 Copper  5.6-8.0 Iron   0-0.8 Magnesium  0.5-1.5 Nickel 0.05-0.9 Manganese   0-1.0 Titanium 0.05-1.2 Zirconium 0.12-1.2 Vanadium 0.05-1.2 Zinc 0.05-0.9 Strontium 0.001-0.1  Aluminum balance. In this alloy the ratio of silicon:magnesium is 10-25, and the ratio of copper:magnesium is 4-15. After an article is cast from this alloy, the article is treated in a solutionizing step which dissolves unwanted precipitates and reduces any segregation present in the original alloy. After this solutionizing step, the article is quenched, and is then aged at an elevated temperature for maximum strength.

    摘要: A pencil sharpener has an electrical motor which drives a sharpening assembly. The end of the pencil to be sharpened is inserted downwardly into an opening in the top surface. Shavings from the sharpening process are deposited in a drawer-like receptacle below the sharpening assembly. A switch is provided so that the sharpening assembly will not be activated when the receptacle drawer is removed for disposal of the shavings.

    摘要: A method for transforming a cast component made of modified aluminum alloy by increasing the impact toughness coefficient using minimal heat and energy. The aluminum alloy is modified to contain 0.55%-0.60% magnesium, 0.10%-0.15% titanium or zirconium, less than 0.07% iron, a silicon-to-magnesium product ratio of 4.0, and less than 0.15% total impurities. The shortened heat treatment requires an initial heating at 1,000° F. for up to 1 hour followed by a water quench and a second heating at 350° F. to 390° F. for up to 1 hour. An optional short bake paint cycle or powder coating process further increases the impact toughness coefficient of the cast component.
