摘要： It has been found that a small amount of alkylene oxide prevents Pt-Co color buildup in mono, di and triethanolamine. Alkylene oxide also reduces undesirable blue, aqua or straw hues which may develop.
摘要翻译：已经发现少量的环氧烷防止单，二和三乙醇胺中的Pt-Co颜色累积。氧化烯还会降低可能发展的不希望有的蓝色，水色或者稻草色调。

摘要： A method of eliminating color-causing impurities in mixtures of aminoethylpiperazine, polyoxypropylenediamines and alkylphenols by treatment with N,N-diethylhydroxylamine is described. These alkylphenols such as nonylphenol are used in epoxy resins in the automotive and electronics industry. Discoloration of the phenol and subsequent resin occurs if the phenol is not treated with N,N-diethylhydroxylamine. Quantities on the order of 20 to 500 ppm are effective. The decolorization reaction may be conducted at a temperature in the range from about 25.degree. to 50.degree. C.
摘要翻译：描述了通过用N，N-二乙基羟胺处理来消除氨基乙基哌嗪，聚氧丙烯二胺和烷基酚的混合物中的着色杂质的方法。这些烷基酚如壬基酚用于汽车和电子工业的环氧树脂中。如果酚不用N，N-二乙基羟胺处理，则发生苯酚和随后的树脂的变色。数量在20到500 ppm之间是有效的。脱色反应可以在约25〜50℃的温度下进行。

摘要： A method and apparatus for sharpening clockwise rotating standard blades, counter-clockwise rotating standard blades and mulching style blades of either clockwise or counter-clockwise rotation is provided. The present invention comprises a base with a blade fixture which is reversible to accommodate both clockwise and counter-clockwise rotating blades. Uprights, a slide shaft, a slide bushing and a handle shaft connected to a disc grinder provide a means for setting a primary cutting angle for sharpening the primary cutting edges of a blade. An adjusting wheel rotatable attached to the handle shaft and pivotably coupled to the disc grinder provide a means for quickly and easily adjusting the cutting angle in order to accommodate sharpening the secondary cutting edges of a mulching style blade and returning the disc grinder back to its original cutting angle.
摘要翻译：提供了用于锐化顺时针旋转的标准叶片，逆时针旋转的标准叶片和顺时针或逆时针旋转的覆盖式叶片的方法和装置。本发明包括具有刀片固定装置的基座，其可逆地适应顺时针和逆时针旋转的叶片。立柱，滑动轴，滑动套管和连接到盘式磨床的把手提供了用于设定用于磨削刀片的主切削刃的主切削角的装置。可旋转地附接到手柄轴并且可枢转地联接到盘式磨碎机的调节轮提供了一种用于快速且容易地调节切割角度的装置，以便容纳锐化覆盖式刀片的二次切割边缘并将盘式研磨机返回其原始切割角度
