TL;DR: In this article, the basic design features and the frequency stability and accuracy capabilities of a proposed new frequency standard are projected and the hydrogen storage beam tube combines the virtues of the hydrogen maser with those of beam tubes and eliminates some of the problems associated with these devices.
Abstract: The basic design features and the frequency stability and accuracy capabilities of a proposed new frequency standard are projected. The hydrogen storage beam tube combines the virtues of the hydrogen maser with those of beam tubes and eliminates some of the problems associated with these devices. The projected frequency stability for 1 s averaging is better than 10-14. The long-term stability should be equally good. Ways for investigating the wall shift are discussed.

TL;DR: In this paper, the authors investigated thirty-five alloys to determine their susceptibility to hydrogen embrittlement at and below design pressures of 5000 to 6000 psi and found that they were all susceptible to hydrogen environment embrittlements.
Abstract: Hydrogen environment embrittlement causes failure of hydrogen storage vessels at and below design pressures of 5000 to 6000 psi. Investigation of thirty-five alloys determines their susceptibility to such embrittlement.

TL;DR: In this article, the hydrogen maser frequency shift due to atomic collisions with deformable storage bulb surface was investigated. But the maser was not found to have a significant effect on the performance.

TL;DR: In this paper, a hydrogen storage electrode for use in a storage cell, for example one in which the other electrode comprises an air or oxygen electrode, comprises a mass of a material with a large surface area, preferably in particulate form, with at least the surface layer comprising a titanium alloy which has a beta structure at the operating temperature of the cell and at least a surface has thereon at least one metal such as Fe, Mo, Ni, Pt, Ir, Rh, Pd, Os or Ru which facilitates the entry of hydrogen into and out of the titanium alloy.
Abstract: 1,209,083. Energy storage systems. IMPERIAL METAL INDUSTRIES (KYNOCH) Ltd. 24 Jan., 1969 [7 Feb., 1968], No. 6063/68. Heading H1B. [Also in Division C7] A hydrogen storage electrode for use in a storage cell, for example one in which the other electrode comprises an air or oxygen electrode, comprises a mass of a material with a large surface area, preferably in particulate form, with at least the surface layer comprising a titanium alloy which has a beta structure at the operating temperature of the cell and at least the said surface has thereon at least one metal such as Fe, Mo, Ni, Pt, Ir, Rh, Pd, Os or Ru which facilitates the entry of hydrogen into and out of the titanium alloy. The whole of the mass may consist of titanium alloy which term includes substantially pure titanium metal. All-beta phase alloys which can be used are binary alloys of titanium with at least 15 weight per cent molybdenum, or with more than 15 weight per cent vanadium, or with more than 30 weight per cent niobium, or with more than 40 weight per cent tantalum. An alloying metal which also facilitates the diffusion of hydrogen may be used, and may be the same as the element on the surface of the alloy, e.g. molybdenum.
