摘要
In devices provided with an evacuated bulb in which is present an activated metallic getter, hydrocarbons can be released or produced. As a result, the gas pressure and the heat conductivity increase. In devices according to the invention, for example, low-pressure sodium vapour discharge lamps, solar collectors, display tubes and image intensifiers, a getter auxiliary means is provided. The auxiliary means comprises an inorganic porous carrier charged with a transition metal having an atomic number from the series 23 to 29, 41 to 47 and 73 to 79, in elementary form or in oxide form, or with a combination of at least two of the said materials.
