摘要:
An apparatus for condensing metal vapors has at least one inlet conduit that is cooled to cause a portion of the metal vapor to condense to liquid. The apparatus also has a holding tank that is connected to the inlet conduit that collects condensed liquid metal. The apparatus also has at least one outlet conduit connected to the holding tank that is cooled to cause a portion of the remaining metal vapor to condense to solid metal. The apparatus also has at least one heater that heats the at least one outlet conduit to cause the solid metal to melt to liquid metal and subsequently flow in to the holding tank. The apparatus also has at least one sealing mechanism located at a distal end of the at least one outlet conduit for preventing metal vapor and carrier gas from exiting the outlet conduit during heating of the outlet conduit.

摘要:
Method and apparatus for minimizing unwanted dynamics in a physical system response. Constraints on the input and on the unwanted dynamics are established, and an impulse sequence which satisfies the constraints is determined. The impulse sequence is convolved with an arbitrary command input to produce a shaped input which is used to drive physical system, thereby minimizing unwanted dynamics. The constraints on the input and on the unwanted dynamics may be selected to achieve shaped inputs and residual unwanted dynamics of various characteristics.
