A device for releasing water vapor in electron tubes comprises a holder and a water vapor releasing material carried by said holder. In one embodiment the water vapor releasing material is a hydroxide or hydrated oxide of a metallic element in combination with a binder. In another embodiment it is hydrated alumina.

Water vapor releasing composition of matter and device, and process for

For the introduction of an alkali metal vapor into an electron discharge lamp or an electron discharge tube, in particular for the vapor deposition of surfaces for photo-emission or secondary electron emission in such a tube, generators are used with a filling which comprises at least one alkali metal as a compound with either boron or silicon. Such filling can be mixed with additional metals.

A getter device with an organosilane coating.

Air-bakeable water-proof getter device and method of manufacturing same

A getter pump comprising two getter elements wherein the first getter element comprises a metallic substrate having a nonevaporable getter metal embedded therein. The second getter element employs a getter metal having a lower hydrogen equilibrium vapor pressure than that of the first getter element.
