    • A pressure gauge for determining air pressure of an inflatable item and a method of doing the same are provided. Embodiments of the present invention provide a source of light capable of providing more than one color of light, where each color of light within the more than one color of light corresponds to a numerical relationship between a determined pressure of an inflatable item, determined by the pressure gauge, and a target air pressure. The pressure gauge also has a display panel for displaying the determined air pressure and at least one of the provided colors of light. In addition, the pressure gauge has a pressure sensor for determining the determined air pressure and a computer defining functions performed by the pressure gauge, wherein the computer causes the source of light to display the different colors of light in accordance with the numerical relationship between the determined air pressure and the target air pressure.

    • A single crystal casting having substantially improved high-temperature oxidation resistance, hot corrosion (sulfidation) resistance, and resistance to creep under high temperature and high stress is characterized by an as-cast composition comprising a maximum sulfur content of 0.5 ppm by weight, a maximum phosphorus content of 20 ppm by weight, a maximum nitrogen content of 3 ppm by weight, a maximum oxygen content of 3 ppm by weight, and a combined yttrium and lanthanum content of 5-80 pm by weight. It has been discovered that careful control of the deleterious impurities, particularly sulfur, phosphorus, nitrogen and oxygen, in combination with a carefully controlled addition of yttrium and/or lanthanum provides unexpected improvements in corrosion and oxidation resistance, while also enhancing high-temperature, high-stress resistance to creep, without any detrimental effects on other mechanical properties, processing or producability, particularly castability.
    • 具有显着提高的高温抗氧化性,耐热腐蚀(耐硫化)性,耐高温和高应力下的蠕变性的单晶铸件的特征在于包含最大硫含量为0.5重量ppm的铸态组合物, 最大磷含量为20重量ppm,最大氮含量为3重量ppm,最大氧含量为3重量ppm,组合钇和镧含量为5-80微米。 已经发现,仔细控制有害杂质,特别是硫,磷,氮和氧,结合仔细控制的钇和/或镧添加,提供了耐腐蚀和抗氧化性的意想不到的改进,同时还提高了高温, 高应力耐蠕变性,对其他机械性能,加工或可生产性,特别是浇注性没有任何不利影响。
