In 1925 Dr.Donle left Connecticut and Electric Company to establish his own company, the Donle Bristol Corporation of Meriden, Connecticut, where later sodion types were developed and manufactured. See Tyne, beginning page 336. The S11 tube is a sodium vapour detector tube and uses a "collector" element near the filament but not actually between the filament and the anode.
