Abstract
A getter assembly is provided and includes a first canister, an internal can including getter, and a second canister. The internal can is disposable in the first canister to occupy a first position at which the getter is hermetically sealable and second positions at which the getter is exposed to an exterior environment. The second canister is engageable with the first canister to drive movements of the internal can between the first position and the second positions following activation and hermetic sealing of the getter.

A getter assembly, comprising:
- a first canister;
- an internal can comprising getter,
- the internal can being disposable in the first canister to occupy a first position at which the getter is hermetically sealable and second positions at which the getter is exposed to an exterior environment;
- and
- a second canister which is coupled with the internal can and engageable with the first canister to drive movements of the internal can between the first position and the second positions following activation and hermetic sealing of the getter.
A getter assembly, comprising:
- a first canister having a valve opening;
- an internal can comprising a valve element, getter, vents and braze alloy,
- the internal can being disposable in the first canister to occupy a first position at which the valve element closes the valve opening to be positioned to hermetically seal the getter with the braze alloy melted into the vents and second positions at which the valve element is displaced from the valve opening to expose the getter to an exterior environment via the valve opening;
- and
