Abstract: A sealed, passively pumped, polycrystalline ceramic vacuum chamber and method for fabricating the chamber are disclosed. The body of the vacuum chamber is made from a polycrystalline ceramic, for example, alumina. The vacuum chamber includes one or more windows made from a transparent ceramic, for example, sapphire, to accommodate optical access, while remaining amorphous-glass free to minimize or eliminate helium permeation. The vacuum chamber components are joined via laser welding or furnace brazing and the completed chamber is bakeable at temperatures up to 400° C. The vacuum chamber can operate at high or ultra-high vacuum pressures for an extended period through the use of one or more getter-based pumps. The vacuum chamber may include one or more atomic sources depending upon the application.

Abstract: A glass lined reaction tank for chemical and pharmaceutical industries and a manufacturing method thereof. One-step molding technical standards for manufacturing iron blanks of the glass lined reaction tanks are deeply developed, an overall structure of a flanged big flange of a tank body and a tank cover matching with the tank body are innovated, and nominal pressure of the big flange and the sealing performance of a tank mouth are perfectly improved. By using a new structurally-combined precise controlled internal heating type electric furnace and an intelligent temperature program control/adjustment/recording instrument, heating temperature of an overall glass lining layer on an inner wall of the tank body is more accurately controlled to be the same, and a synchronous, integral and controlled sintering core technique is realized.

Abstract: A vessel system for high-pressure reactions is disclosed. The system includes a plugged polymer cylinder reaction vessel with a pressure vent opening extending radially through the wall of the reaction vessel and a supporting frame into which the vessel is received. Complementing keying structure elements on the vessel and on the frame limit the orientation of the reaction vessel in the supporting frame and the radially extending vent opening to a defined single position.

Abstract: Improved hydrochlorination reactors, which have a larger internal volume and hence functional capacity than presently available hydrochlorination reactors, may be prepared with reactor walls having inner and outer layers where each layer provides a unique benefit, the inner layer having hydrogen chloride resistance and the outer layer having high strength at elevated temperature and pressure. Alternatively, or additionally, hoops may be disposed along the outside of the reactor wall to provide additional strength to the reactor during operation. Specified materials may be used to form the reactor wall in order to provide both acid resistance and high strength at elevated operating temperatures.
