| Description |
Abraham, M. René Jounaust, Michel Peri and Jacques Biguet worked first at Établissements Bocuze for precious metals used in gauze (lamé) but were assigned in about 1914 to Grammont for designing tubes. They ended up in a cylindrical coaxial construction, mounted horizontally and Peri/Biguet applied for a patent on this construction on October 23, 1915, including the 4-Pin-base.
Peri/Biguet sold the patent later to Marius Latour who then amassed quite a fortune on royalties on that Peri-Biguet patent. This outraged Peri so much that he spent years trying to design tubes wich would not infringe the Peri-Biguet patent - but never really succeeded. This tube is one of these Peri designs, shown by Tyne on page 197. See also the Junot-Tube here at Radiomuseum.org.
