    摘要: Method for converting reactive gases which are sucked in at a low inlet pressure and are expelled at a higher outlet pressure by a dry multi-stage pump, in which method the reactive gases are physically and/or chemically converted into nonreactive components at a pressure situated between the inlet and outlet pressure, the conversion taking place, according to the invention, by means of gas discharge. The invention also relates to a dry multi-stage vacuum pump (3) and a plasma scrubber (4) which are particularly suitable for use in the method according to the invention.

    摘要: Surface coating includes alternating first and second ternary layers, wherein the first layer TiAlN.sub.x has a higher nitrogen content and is considerably thinner than the second layer TiAlNy. The first layer is preferably applied by decreasing the nitrogen content of a reactive atmosphere from a maximum to a minimum during sputtering of a TiAl target. The second layer is then applied by sputtering the TiAl target over a longer period of time while the nitrogen content is maintained constant at the minimum. When a further first layer is applied, the nitrogen is again increased to the maximum.

    摘要: The invention relates to a method and apparatus for the purification and recirculation of gases which are fed to a plant for the production of metal powder or for compacting metal powder at elevated pressures. The operating gas exits the plant at a lower pressure and is conveyed in a closed loop, in which filters are provided for the mechanical and/or chemical purification of the gases as well as means for increasing the pressure of the purified gas. The repressurization of the operating gas is carried out economically by liquefying the operating gas leaving the plant after purification by the application of liquid nitrogen, then feeding the liquefied gas to an evaporator via a high-pressure pump, and finally returning the operating gas to the plant in a pressurized gaseous phase.

    摘要: A leak indicator for detecting leaks in a vacuum system including a chamber and a system vacuum pump. The indicator is provided with a mass spectrometer for identifying the presence of a test gas in the system chamber and a high vacuum pump for producing the pressure required for operation of the mass spectrometer during a system leak test. A sealed conduit network is provided to connect the system chamber to the inlet of the mass spectrometer, and to the inlet side and exhaust side of the high vacuum pump. A first switching valve is provided within the sealed conduit in series between the system chamber and the inlets of the mass spectrometer and the high vacuum pump. Lastly, a constriction member is connected within the network conduit in series between the system chamber and the first switching valve to selectively provide a direct connection between the system chamber and the inlet side of the high vacuum pump, or between the system chamber and the exhaust side of the high vacuum pump.
