    摘要： Disclosed is a method for producing unsaturated fatty acids from unsaturated aldehydes by means of fixed-bed catalytic partial oxidation in a shell-and-tube reactor, characterized in that the reactor includes a reaction zone for producing unsaturated fatty acids, the reaction zone having an inactive material layer inserted into a position where a hot spot is to be generated in a reaction tube. A fixed-bed shell-and-tube reactor for use in the above method is also disclosed. According to the present invention, at least one layer of inactive material is packed at the point of a hot spot to control the hot spot temperature efficiently, thereby increasing the lifetime of a catalyst and producing unsaturated fatty acids with high yield.

    摘要： A stretcher comprises a patient support area supported by front legs and rear legs. The front legs and rear legs are coupled by a gear mechanism, and an actuation device coupled to the gear mechanism effects retraction or extension of the stretcher in a smooth and continuous motion. The actuation device is operable to lock the gear mechanism to position the stretcher at any desired height between fully extended and fully retracted.

    摘要： An apparatus to control displacement of a body spaced-apart from a surface includes a flexure system having a first flexure member defining a first axis of rotation and a second flexure member defining a second axis of rotation. A body is coupled to the flexure system to move about a plurality of axes. An actuation system is coupled to the flexure system to selectively constrain movement of the body along a subset of the plurality of axes.
