Definitions

  • This invention relates to getter holders and more particularly to holders of the kind having at least one open cavity of substantially U-shaped cross-section.
  • FIGS. 1, 2, 3, and 6, respectively, show getter holders known in the prior art.
  • FIGS. 4 and 7 show two embodiments of a getter holder according to the invention.
  • the getter vapour it is desirable for the getter vapour to escape straightly forwards so that use may be made of a holder 3 of the kind shown in FIG. 2 or 6 in FIGS. 5 and 6.
  • the holder 6 shown in FIGS. 5 and 6 is in the form of a steel band with cavities pressed in it, into which getter powder 1 is pressed.
  • this powder cannot satisfactorily be held in place so that it readily loosens, whilst the holder 4 shown in FIG. 3 has been found in practice to be even wholly unserviceable as a result of this difiiculty.
  • FIG. 4 shows part of an annular holder comprising a steel band 5 which has a circular groove and the base of which has a groove 8 of a shape such as to be spherical towards the interior. Such is also the case with the base 9 of the holder '7 shown in FIG. 7.
  • the getter powder consists, for example, of a mixture of nickel and/ or a nickel-titanium compound and a barium-aluminum alloy.
  • the invention is also important for non-evaporating getter powders containing, for example, zirconium.
  • a container for solid getter material comprising a channel shaped tube having opposing side walls and bottom wall connecting the side walls Within which a body of compressed powdered getter material is packed, said bottom wall being curved convexly toward the interior of the channel to retain the getter material in said channel.
