Siemens & Halske AG (or Siemens-Halske) was a German electrical engineering company that later became part of Siemens. It was founded on 12 October 1847 as Telegraphen-Bauanstalt von Siemens & Halske by Werner von Siemens and Johann Georg Halske .
The Siemens & Halske T52, also known as the Geheimschreiber [1] ("secret teleprinter"), or Schlüsselfernschreibmaschine (SFM), was a World War II German cipher machine and teleprinter produced by the electrical engineering firm Siemens & Halske. The instrument and its traffic were codenamed Sturgeon by British cryptanalysts.
Siemens & Halske was founded by Werner von Siemens and Johann Georg Halske on 1 October 1847. Based on the telegraph, their invention used a needle to point to the sequence of letters, instead of using Morse code. The company, then called Telegraphen-Bauanstalt von Siemens & Halske, opened its first workshop on 12 October. [11]
In 1847 Halske founded the Siemens & Halske Telegraph Construction Company together with Werner von Siemens. [1] Halske was particularly involved in the construction and design of electrical equipment such as the press which enabled wires to be insulated with a seamless coat of gutta-percha , the pointer telegraph and the morse telegraph and ...
Animation of the engine as it would have been seen looking at the front of the aircraft. The Siemens-Halske Sh.III was an 11-cylinder counter rotary engine. [1] The Sh.III's propeller and cylinders were connected, these rotated anti-clockwise when viewed from the front of the aircraft (clockwise when viewed from the pilot's seat) while the crankshaft rotated clockwise.
It was founded by the German industrialist Werner Siemens in 1879 as a factory of the Siemens & Halske company for the production of lamps, cables, and switches. [2] In 1918, the factory was nationalized and given its present name. It subsequently made a substantial contribution to the electrification of the entire USSR. [citation needed]
The Albatros D.XI was a German single-seat fighter sesquiplane first flown in February 1918. It was the first Albatros fighter to use a rotary engine, in the form of the 120 kW (160 hp) Siemens-Halske Sh.III, and also featured a new wing construction with diagonal struts from the fuselage replacing traditional wire bracing.
The definitive version of the aircraft was the Fw 44C, which was powered by a Siemens-Halske Sh 14 radial engine instead. [6] The last series version was the Fw 44J, which was sold or built under license in several countries around the world.
