Abstract: Getter devices for halogen lamps are formed by screen-printing a paste comprising tantalum, thorium, hafnium, platinum, niobium or zirconium, and preferably zirconium and tantalum, in strips onto a metallic foil and then cutting the strips perpendicularly. The resulting foil strips can be cut parallel to the getter material to form pieces that contain a small area of getter material and an area of foil. The foil area can be used to mount the getter device to a support structure in the inner quartz bulb of the halogen lamp. The getter device maintains the purity of the gas surrounding the tungsten filament. The getter material is suitable for use in any halogen lamp and especially for halogen lamps having small quartz bulbs.

Abstract: A process for producing a device for mercury dispensing, reactive gases sorption and electrode shielding within fluorescent lamps, commonly called "shield", is described. The shield is formed by shaping a piece of a metallic strip having deposited thereon, on the same face, one or more tracks of powdered mercury-dispensing materials and getter materials. The operation of deposition of such materials on the strip is realized in such a way so as not to cause the deformation of the strip.

Abstract: A device for maintaining vacuum in thermally insulating jackets comprises a container (11; 21) which is open upwards and formed of a gas-tight material, preferably aluminum, with a first pellet (13; 23) on the bottom and a second pellet (15; 24) placed in the upper portion of the container, such as to completely cover the first pellet (13; 23). The first pellet is obtained from powders of a Ba-Li getter alloy and the second pellet (15; 24) is obtained from powders of a drying material, optionally including also the oxide of a noble metal and a material avoiding compaction of the drier. There is also described a process for manufacturing such a device, according to which said first pellet of Ba-Li alloy can be obtained locally by compression of powders of said alloy within the container. The upper edge of the latter is finally bent to the inside, whereby the pellets are held to keep their position.
