Patent FI-1911-4528

• Patent title is in Swedish. Several lines on the patent document are handwritten apparently by the patent office.
• A fully typed out version in Swedish takes 4 pages, and another is identical but in Finnish, and takes 3 pages.
• No filing date is shown but the diagrams are identical to the French parent filed 1911-01-31 so it was presumably filed soon after that.
• It is not clear why Canda would have filed in Finland; perhaps he was a Finnish immigrant to France, or a Finn visiting France.
• Inventor location and occupation: Paris, Frankrike ; Fabrikant (presumably meaning the same as Manufacturer, as written on other Canda patents)
