A non-evaporable getter alloy is provided which can be used in a process for the sorption of gas from a closed vessel comprising the step of:
Polyisocyanurate foams are produced by admixing from separate sources, an organic polyisocyanate, a diol, and a catalytic composition which comprises an alkali metal carboxylate and polyoxyethylene polyol.
A device for the removal of hydrogen from a vacuum enclosure at cryogenic temperatures, especially high energy particle accelerators which comprises a metal support preferably in the form of a strip of aluminium and a composition able to sorb hydrogen adherent to the support in particular on at leas ...
A calibrating apparatus for isothermally introducing, into a stream of dry gas, amounts of moisture lower than 1000 ppb, said apparatus comprising:
Described is a dual magazine assembly comprising a left magazine and a right magazine held together by a holder. The assembly permits either magazine to be received by a firearm even when the firearm has only a single magazine port. The holder comprises a female half, and a male half.
A getter device comprising a carrier having on at least one of its faces particles of a nonvaporative getter metal characterized in that the particles of the getter metal are partially embedded in the carrier to give a highly efficient getter device.
An improved high-capacity getter pump, comprising a plurality of porous sintered piled-up annuli made from a non-evaporable getter material and having: i) a first planar surface having a central hole; ii) a second planar surface, having a broader central hole, parallel to said first surface and spac ...
This invention relates to a method for the production of non-evaporable ternary gettering alloys of the type Zr-M.sub.1 -M.sub.2 in which M.sub.1 is a metal chosen from the group comprising vanadium and niobium, and in which M.sub.2 is a metal chosen from the group comprising iron and nickel.
A see-through magazine of a polyamide composition in which cartridges within the magazine are visible through the composition of the walls. The magazine holds and feeds cartridges to a bolt-equipped firearm. The magazine has a front wall, a back wall, and two sidewalls joining the front wall to the ...
The scope of the present invention is the provision of a non-evaporable gettering ternary alloy particularly for the sorption of water and water vapor in nuclear reactor fuel elements.
