Marconi Communications
Marconi Communications, the former telecommunications arm of Britain's General Electric Company plc (GEC), was founded in August 1998 through the amalgamation of GEC Plessey Telecommunications (GPT) with other GEC subsidiaries: Marconi SpA, GEC Hong Kong, and ATC South Africa.

Coffman Starter
The Coffman engine starter (also known as a "shotgun starter") was a starting system used on many piston engines in aircraft and armored vehicles of the 1930s and 1940s. It used a cordite cartridge to move a piston, which cranked the engine. The Coffman system was one of the most common brands; another was the Breeze cartridge system, which was produced under Coffman patents. Most American military aircraft and tanks which used radial engines were equipped with this system. Some versions of the Rolls-Royce Merlin engine used in the UK, British Supermarine Spitfire used the Coffman system as a starter. The Hawker Typhoon and Hawker Tempest also used the Coffman system to start their Napier Sabre engines. Cartridge starters used on a number of jet engines, including such engines as the Rolls-Royce Avon, which were used in the English Electric Canberra and Hawker Hunter aircraft, used a high gas volume cartridge driving a turbine instead of a piston.
