Straight line linkage Peaucellier mechanism

quote [ The Peaucellier?Lipkin linkage (or Peaucellier?Lipkin cell, or Peaucellier?Lipkin inversor), invented in 1864, was the first true planar straight line mechanism ? the first planar linkage capable of transforming rotary motion into perfect straight-line motion, and vice versa. It is named after Charles-Nicolas Peaucellier (1832?1913), a French army officer, and Yom Tov Lipman Lipkin (1846?1876), a Lithuanian Jew and son of the famed Rabbi Israel Salanter. ]

If your favorite site or app is down right now, this is why

quote [ it appears it's more than "older devices" that have tripped up and stopped working as expected ? such as refusing to establish secure connections to remote systems ? and that may be due to an issue with the now-expired R3 intermediate, or because your client doesn't recognize the ISRG root cert. ]
