Abstract
A getter capsule comprising at least one particular container (1 or 10) containing getter particles (9) is useful for removing reactive gases in at least one vacuum space(21d or 22d). The particular container (1 or 10) may be made of a material containing sintered particles or may be made of a combination of a filtering means (11) and a perforated inorganic pipe or cup (12). At least one closing means (5 or 15) employed in each container (1 or 10) to close or cover the opening (4 or 14) of the container (1 or 10) may be particularly designed to prevent the getter particles (9) from escaping the container (1 or 10) without using any sealants, even when the container (1 or 10) is subject to vibrations.
Claims17
A getter capsule capable of being installed in a vacuum system, said getter capsule comprising a container having at least one interior cavity and getter particles placed within said at least one interior cavity of the container, the container comprising at least one enclosure wall defining said at least one interior cavity, at least one opening providing access into said at least one interior cavity and at least one closing means covering or closing said at least one opening, thus maintaining said getter particles within said at least one interior cavity, wherein said at least one enclosure wall or said at least one closing means is porous and is constructed with a material comprising sintered particles.
A container capable of being used as a getter capsule in a vacuum system, said container comprising at least one perforated inorganic wall defining at least one void volume, at least one opening providing access into said at least one void volume, at least one porous filtering means containing a plurality of pores having a pore diameter in the range of about 0.02 to about 200 micrometers placed within said at least one void volume to cover the perforations of said at least one perforated inorganic wall, and at least one closing means for closing or covering said at least one opening.
A container capable of being used as a getter capsule in a vacuum system, said container comprising at least one enclosure wall defining at least one interior cavity, at least one opening providing access into said at least one interior cavity and at least one closing means releasably or removably covering or closing said at least one opening so that getter particles can be placed within or removed from said at least one interior cavity, wherein said at least one enclosure wall or said at least one closing means is porous and is constructed with a material comprising sintered particles.
A vacuum insulated equipment comprising:
- at least one enclosure wall defining at least one void volume or passageway, at least one vacuum jacket surrounding said at least one enclosure wall to form at least one vacuum space therebetween, at least one insulation surrounding at least portion of said at least enclosure wall within said at least one vacuum space and at least one getter capsule within said at least one vacuum space, said getter capsule comprising a container having at least one interior cavity and getter particles placed within said at least one interior cavity of the container, the container comprising at least one wall defining said at least one interior cavity, at least one opening providing access into at least one interior cavity and at least one closing means covering or closing said at least one opening, thus maintaining said getter particles within said at least one interior cavity, wherein said at least one wall or said at least one closing means is porous and is constructed with a material comprising sintered particles.
