Gas turbine product range Industrial Gas Turbines of note manufactured at the Lincoln plant: TA TB TD Typhoon (SGT-100) Tornado (SGT-200) Tempest (SGT-300) Cyclone (SGT-400) Boilers Until the late 1960s, it produced Thermax boilers. The boiler business was sold for £1.75m to Cochrane & Co of Annan, Dumfries and Galloway in October 1968, that was bought by John Thompson of Wolverhampton four months later. It was bought by Clarke Chapman in 1970. Energy schemes In 1957, it was the first company to fit a main Royal Navy ship (HMS Cumberland) with a (experimental) gas turbine. In 1959, it opened a new type of power plant using waste sewage gas that powered eight turbines at Britain's biggest sewage works at the Northern Outfall Sewer at Beckton in East London. This was an 18,000 horsepower combined heat and power plant. The company pioneered combined heat and power schemes. The company began this technology in Cortemaggiore, Emilia-Romagna in 1956 at the Agip (Azienda Generale Italiana Petroli) oil refinery. By the late 1960s, Ruston & Hornsby CHP units were installed in Australia, Germany, the US, South America, and the Middle East. In the 1970s, these CHP schemes were not as well developed as today because electricity companies were not interested in developing a market that would provide direct competition to themselves. CHP schemes were then known as total energy schemes, which comprised exhaust heat recovery. The company won the Queen's Award for Enterprise: International Trade (Export) in 1977, 1978 and 1982. The large Singer factory in Clydebank, which employed 11,000 people, was notably powered by Rustons turbines. The King Faisal Specialist Hospital was installed with a CHP unit in 1975. Whitehall in London is heated and has its electricity from a CHP unit built in the late 1990s. Ownership and acquisitions Paxman In 1940 R&H bought a controlling interest in the well-known Paxman diesel engine company of Colchester in Essex. In the later stages of the war, Paxman built 4,000 diesel engines that powered all the British-built tank landing craft (LCT) on D-Day. It supplied diesel engines for British Rail locomotives in the 1960s. From 1954 to 1964 the company's Managing Director was Geoffrey Bone who had been part of the Power Jets team, and whose father Victor Bone was Managing Director of R&H from 1944 until his death. It was due to Geoffrey Bone that Bob Feilden was recruited for R&H who subsequently
