Historical SECO SEALS document – Post 2 is from Voi-Shan which introduces the “The Conical Seal” and includes the “Interim Report No. AN AN59MD3008-1, Flared Tubing – Survey of Concentricity” regarding the “Problem and leakage on High Pressure Lines” for sealing helium
We have retained engineering documents going back to the early days of the USA space program in the late 1950’s. We are sharing these documents to show what happened at the time, what we learned, and what we are still using today.
In an article posted on https://phys.org about the Antarctic ozone hole, “University of Otago researchers believe chlorofluorocarbons (CFCs) aren’t the only things to blame.” This study highlights need to monitor the ozone hole. “Lead author Hannah Kessenich, Ph.D. candidate in the Department
NASA and NOAA researchers find that “The 2023 Antarctic ozone hole reached its maximum size on Sept. 21, according to annual satellite and balloon-based measurements made by NASA and NOAA. At 10 million square miles, or 26 million square kilometers, the hole
According to scientists, “the annual ozone hole that forms over Antartica has ballooned to near-record size…” “Measurements from satellite imaging taken on Sept. 16 showed that the ozone depletion area had reach 26 million square kilometers — roughly three times the size
The refueling arm of NASA’s Restore-L Servicer utilizes SECO7, 37-conical seals. Following is a short excerpt from NASA Space Tech, released on June 23, 2016, regarding this project. “…In May, NASA officially moved forward with plans to execute the ambitious, technology-rich Restore-L
