Abstract: An inner lid is attached to a vacuum chamber, covering an inner region of the vacuum chamber. An outer lid, also attached to the vacuum chamber, covers the inner lid, leaving a region between the inner lid and the outer lid. A gas conduit allows gas to flow between the inner region of the vacuum chamber and the region between the inner lid and the outer lid. A filter is placed in or immediately outside the gas conduit to prevent particles from entering the inner region of the vacuum chamber from the region between the inner lid and the outer lid. Since the pressure is the same on the top and bottom of the inner lid, the inner lid does not flex and thus does not rub against the vacuum chamber when the vacuum chamber is pumped down or vented up.

Abstract: A system for precisely controlling gas under high pressure produces an initial gas pressure in a pressure chamber while applying a predetermined amount of power to a heating element located in the pressure chamber and then applies a computed change of power to produce an average gas temperature increase or decrease in the pressure chamber and thereby rapidly produce an increase or decrease in gas pressure with resolution limited by the resolution of measurement of gas pressure in the pressure chamber and the application of the computed change of power. The described invention is particularly advantageous at gas pressure above roughly 1000 pounds per square inch.

Abstract: The invention proceeds from a vacuum process apparatus for an article which is processed or treated, resp. at two stations, whereby each station has a charging and/or removing opening for the article. A transporting device is supported for rotation and includes a supporting portion which is successively moved onto the openings of the stations. The process plant is designed in such a manner that the surface normals determined by the surfaces of the openings and the space axis defined by the axis of rotation of the transport device do not run parallel and rather enclose together an angle of 90.degree. or 45.degree.. By such an arrangement it is possible to design extremely compact vacuum vapor deposition apparatuses having a plurality of individual stations, whereby additionally short transporting distances are obtainable and the volumes to be conditioned can be minimized.

Abstract: A method and apparatus for delivering supercritical fluids uses one or two high pressure vessels. Each vessel is cooled below the critical temperature of the fluid while the vessel is being filled. The inlet is then closed and the vessel is heated to attain a predetermined pressure. The outlet of the vessel is then opened and supercritical fluid flows from the vessel for use in various processes such as extraction or chromatography. As the fluid flows from the high pressure vessel, the pressure is controlled by adjusting the temperature of the high pressure vessel. Usually, the temperature of the vessel will be increased as the supercritical fluid exits from the vessel. When two high pressure vessels are used, the vessels can be refilled on an alternating basis so that a continuous supply of supercritical fluid can be made available as long as it is required. The high pressure vessels can be two pieces of stainless steel tubing. The system is essentially maintenance free as there are virtually no moving parts. With previous delivery systems for high pressure fluids, high pressure pumps are used. These pumps are relatively expensive and can be subject to problems such as noise and leakage.

Abstract: A bulk getter-pump, consisting primarily of large beds of heated getter-material for use in pumping down a vacuum chamber to a rough vacuum. The pump is designed for applications now are served by turbo, cryo, diffusion, and ion pumps. The pump consists of a meshed cage filled with bulk getter-material pellets, which cage is housed in a housing coupled to a conduit of a vacuum chamber, so that the bulk getter-material is exposed to the interior of the vacuum chamber. In use, a roughing pump is first used to bring the chamber down to a pressure of about 2 torr, and then the bulk getter-pump of the invention is operatively coupled to the chamber for sorbing gases, in order to reach a desired vacuum.

Abstract: A vaporizer and extractor apparatus for a laser isotope separation process is arranged as an assemblage of modular components in which equipment subject to maintenance is replaceable via vacuum casks while the apparatus is operational or briefly shut down without loss of vacuum. A vacuum transfer cask is provided for modular extractor substrate assemblies. The substrate assemblies are nestable and are mounted on extensible probes which permit them to be nested in the vacuum transfer cask for transport. During use the substrates extend from the cask, through a vacuum lock and are placed side by side in the vacuum chamber. A vacuum transfer cask is also provided for the vaporizer assembly which is mounted on an extensible arm which in turn positions the assembly in the chamber or retraces the vaporizer assembly from the chamber into the transfer cask, rotating it during the process in order to permit it to fit into the cask. The complete vaporizer unit consisting of a crucible, two electron beam guns, a combination thermal/vapor shield and an electrical ground plate along with the associated cooling and electrical services is suspended from the extensible arm out of the vacuum transfer cask.

Abstract: A pressure proof reactor vessel and the method of making such vessel wherein the vessel has a cylindrical one-piece outer shell and a cylindrical one-piece cylindrical inner shell, which inner shell has a smooth continuous interior surface spaced radially inwardly from the outer wall and concentric thereto. The outer cylindrical shell is formed from a one-piece material with its radial thickness being substantially greater than the radial thickness of the inner cylindrical shell. Support means in the form of a spiral or vertically disposed is positioned in the space between the cylindrical outer surface wall of the inner shell and the cylindrical outer shell defining a pathway for the flow of coolant between the outer wall and the inner wall. The support means is secured to the inner surface of the one-piece cylindrical outer shell while the inner shell is plug welded to the support means.
