Kommandogerät der Fliegerabwehr mit vereinfachter Geometrie, 1938–1950: Ein sog. "Winkelgeschwindigkeits-Gerät"
An 11-page German-language technical article by André Masson (2016) describing the simplified angular-velocity fire-control computer (Kommandogerät) developed by the Swiss Federal Arms Factory W+F and manufactured by HASLER AG for the 34 mm anti-aircraft cannon from 1938. The article details the mechanical gear train, cam bodies, stepped-gear angular-velocity input, telephone-impulse-technique (TIT) data transmission to the guns, and manual correction mechanisms, along with a chronology of the device's operational use in Switzerland (1938–1942) and its eventual replacement. This is the fifth in a series of articles by the same author on WWII-era Swiss anti-aircraft mechanical analog computers.
