Despite the similarities, Langmuir emphasised that this pump was fundamentally different from Gaede’s; the cold walls of the ...

REPORTING recently on the vacuums produced by diffusion pumps, Ray and Sengupta 1 quote my statement "that the limit of pumping is set at the vapour pressure of the pump fluid at room temperature" and ...

If you need to create a high vacuum, there are basically two options: turbomolecular pumps and diffusion pumps. Turbomolecular pumps require rotors spinning at many thousands of rotations per minute ...

IIIF provides researchers rich metadata and media viewing options for comparison of works across cultural heritage collections. Visit the IIIF page to learn more. Vapor diffusion pumps developed from ...

Leybold has now expanded its range of oil diffusion pumps to include the Diffvac DP and Diffvac OB series. The new Diffvac DP series offers energy efficiency, robustness and uninterrupted operating ...

THERE has long been a need for a diffusion pump oil which, while hot, would withstand atmospheric pressure without bad effects. G. P. Brown (Rev, Sci. Inst., 16, 316 ; Nov. 1945) has found that ...

Vacuum pumps are everywhere—behind the scenes in air conditioning systems, hospital equipment, laboratories, and even some car engines. This fascinating piece of technology lies behind these everyday ...

It’s hard to miss how much attention AI image generators alone have attracted in recent months. With good reason, because they demonstrate the progress of deep learning models in a vivid and playful ...

Your water pump moves coolant through your engine to help ensure it doesn’t overheat. Without it, your car can essentially die of heat exhaustion. (That means you’ll want to get your water pump fixed ...
