    摘要: The present invention relates to a hydrogenation process for the preparation of aromatic amino compounds containing directly on the aryl ring or in a side chain one or more entities that may also undergo hydrogenation, such as carbon multiple bonds, nitrile groups, imino groups or carbonyl groups. The preparation is carried out by catalytic hydrogenation of the corresponding aromatic nitro compounds in the presence of a phosphorus-modified noble metal catalyst. The invention relates also to the use of modified noble metal catalysts for the hydrogenation of aromatic nitro compounds containing carbon multiple bonds and/or substituted by nitrile, imino or carbonyl groups.

    摘要: An apparatus for supporting a parachute flight controller from a parachute comprises a bearing member, for example a pulley, a load-bearing coupling, for example a harness, connected to the bearing member and including a connector for connecting the coupling to a parachute flight controller. The coupling includes a load-bearing connector for connecting a payload thereto, and the bearing member is adapted to enable relative movement, controlled by the flight controller, between the bearing member and a support member, for example a flexible coupling line or web for supporting the bearing member connected between first and second suspension lines of a parachute. The flight controller may include one or more control lines connected to the support member or suspension lines which can be wound in or out of the flight controller to effect relative movement between the bearing member and the support member and thereby control the direction of the parachute.
