    • 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.

    • The present invention is directed to a novel catalyst composition and its use in the dehydrogenation of paraffins to olefins. The catalyst comprises an alloy of a Group VIII noble metal and a metal selected from the group consisting of zinc and gallium on a support selected from the group consisting of silica, zinc oxide modified silica and zinc oxide modified silica-pillared clays when said alloy is a zinc alloy, and silica, gallium oxide modified silica and gallium oxide modified silica-pillared clays when said alloy is a gallium alloy. The instant catalyst is an active and selective catalyst for the catalytic dehydrogenation of paraffins to olefins, especially gaseous paraffins, having the added benefit of retaining high activity and selectivity even following repeated regeneration by calcination in oxygen containing gas at temperatures of 450.degree. C. to 650.degree. C., preferably 450.degree. C. to 500.degree. C.

    • 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。
