Abstract: The present invention relates to a process and an apparatus for separating and recovering the waste alkali from a cyclohexane oxidation solution, and provides a process and an apparatus for separating and recovering the waste alkali from a cyclohexane oxidation solution. According to the invention, a gradient combination of the gravity separation technique, the vortex separation technique and the coalescence separation technique is used to carry out fine separation of the waste alkali liquor from the cyclohexane oxidation solution. The purified cyclohexane oxidation solution is fed into a down-stream apparatus. Most of the waste alkali liquor thus separated is recycled, while the remaining is expelled. The expelled waste alkali liquor is incinerated in an incinerator, followed by recovering the molten species using a pneumatic pulverization process.

Abstract: A method of operating a metrology instrument includes generating relative motion between a probe and a sample at a scan frequency using an actuator. The method also includes detecting motion of the actuator using a position sensor that exhibits noise in the detected motion, and controlling the position of the actuator using a feedback loop and a feed forward algorithm. In this embodiment, the controlling step attenuates noise in the actuator position compared to noise exhibited by the position sensor over the scan bandwidth. Scan frequencies up to a third of the first scanner resonance frequency or greater than 300 Hz are possible.

Abstract: Systems and methods are described for monitoring the activity of an object to aid in debugging a problem with an application using the object. An operating system registry is altered to reference a proxy object when the application attempts to reference the object. The proxy object exposes an interface exposed by the object. Communications passing between the application and the object can be monitored in the proxy object. The proxy object can be monitored locally or remotely through a remote procedure channel.
