As the vacuum of the X-Ray Tubes intensifies by use they must be fitted with a so-called regene- 

 rating device if the life has to be prolonged to any extent. 



The tubes have osmose regeneration; this is based on the property possessed by palladium to be 

 permeable to hydrogen when in the incandescent state. The device consists of a small palladium tube 

 fused in. When the vacuum in the tube has become too high, i. e. when the tube has become hard, the 

 end of the small palladium tube is made red-hot for a few seconds by means of a spirit lamp, without 

 the flame being allowed to come into contact with the fused part of the glass. Hydrogen is diffused into 

 the tube from the core of the flame through the incandescent palladium tube and the vacuum is 

 lowered, i. e. the tube is rendered softer. The tube should be allowed to cool thoroughly before being 

 used again.
