SHORTLY after the commencement of the war it became evident that if helium were available in sufficient quantities to replace hydrogen in naval and military airships, the losses in life and equipment arising from the use of hydrogen would be enormously lessened. Helium, as is known, is most ...

Helium has just 1/7 the density of air. This sealed helium drive produces less air turbulence, which in turn saves power consumption, produces less heat, produces fewer vibrations, makes less noise, allows greater drive capacity, and results in a much lower total cost of operation. The ...
Gas mixtures with helium are particularly suitable for leak-testing of safety-critical components. But helium is expensive. Modern gas technology from Witt makes it possible to reduce helium consumption, thereby lowering costs significantly.
It deals with the integrated design of blanket ancillary systems related to the use of helium or water as coolants for the blanket and its impact on the overall plant design. Particular focus is given to the issues connected to the BB variants in terms of (i) impact on the overall plant...
Hello, I recently learned about the existence of undetected-chromedriver. Would it be possible to use this as as the main webdriver with helium instead of the default one? If so can anyone point me in the right direction code-wise? Thank you MrBeardedGuy changed the title Is it possible ...

Selected letters and papers dealing with experiments in the use of mixtures of helium and oxygen for undersea operations, 1923-1941. PURPOSE:To suppress the generation of the noises of fluid, to make it possible to decrease self-noises and to improve measuring capability by attaching an underwate...
In combination with oxygen, helium is used in diving to help eliminate nitrogen narcosis, reduce breathing resistance at depth, and shorten decompression stops. Known as heliox, the mixture allows divers to reach greater depths for longer periods of time. The deepe...
