    • A broadhead arrow sharpening accessory adapted to receive a flat file between end blocks for sharpening the broadhead blades. The end blocks contain end slots formed therein for receiving the ends of the file. Parallel rods extend between the end blocks alongside the side edges of the flat file. Support carriages are slidably mounted on the rods for receiving the broadheads with a blade extending outward frictionally engaging a file surface. The carriage and broadhead are moved in unison along the rod with the blade edge frictionally engaging the filing surface to sharpen the blade edge at the desired bevel angle.
    • 一种宽头箭头磨刀配件,适用于在端块之间接收平面文件,用于磨削宽幅刀片。 端块包含形成在其中的端槽,用于接收文件的端部。 平行的杆在平面文件的侧边缘之间的端块之间延伸。 支撑托架可滑动地安装在杆上,用于接收具有向外摩擦地与文件表面接合的刀片的宽头。 托架和宽头杆沿着杆一致地移动,刀片边缘摩擦地接合到压片表面,以便以期望的斜角角度锐化叶片边缘。

    • The present invention is directed to improved zirconia-pillared clays exhibiting high crystallinity and layer spacing and significantly higher thermal stability prepared using zirconyl acetate as the pillaring agent by: (a) mixing a clay selected from the group consisting of smectite clays and fluoromicas with a solution of zirconyl acetate for a time and at a temperature sufficient to form a pillared clay product; (b) separating said pillared clay product formed from the solution; (c) washing the separated pillared clay product with water; (d) drying the separated, washed pillared clay product at a temperature from about 50.degree. to 200.degree. C.; (e) calcining the dried pillared clay product at a temperature from about 300.degree. to 700.degree. C.
    • 本发明涉及改进的氧化锆柱状粘土,其表现出高结晶度和层间距,并且使用乙酸氧锆酯作为起始剂制备了显着更高的热稳定性,其方法是:(a)将选自蒙脱石粘土和氟代核的粘土与 乙酸氧锆溶液一段时间并在足以形成柱状粘土产物的温度下进行; (b)分离由溶液形成的柱状粘土产品; (c)用水洗涤分离的柱状粘土产品; (d)在约50℃至200℃的温度下干燥分离的经洗涤的柱状粘土产品; (e)在约300℃至700℃的温度下煅烧干燥的柱状粘土产品。
