GEC Turbine Generators Ltd was a subsidiary of GEC. Although GEC sold its turbo-generators business in 1966, in the following year the company acquired AEI, which brought turbo-generators back. In 1969 the company established GEC Power Engineering, which included English-Electric AEI Turbine Generators Ltd. The business became known as GEC Turbine Generators Ltd around 1972. GEC Turbine Generators Ltd had its headquarters and steam turbine design centre at Rugby, whilst manufacturing for low pressure turbines was based at Trafford Park, and Stafford manufactured generators. Faced with a slow domestic market in the 1970s GEC Turbine Generators increasingly turned its focus to overseas markets. It won significant contracts for work on power stations in Hong Kong and South Korea, amongst other countries, and by October 1976 could boast that 60-70 percent of its business was in exports. The company was given the Queen's Award for Export Achievement for its steam turbines and associated generators for fossil-fuel and nuclear power stations in 1982. In 1998 GEC Turbine Generators was merged with Compagnie Générale d'Electricité (CEG) and became known as GEC Alsthom Turbine Generators Ltd.

Associated Electrical Industries (AEI) was formed in 1928 as a financial holding company for a number of leading electrical manufacturing and trading companies in the United Kingdom. The two major constituent companies were British Thomson-Houston (BTH) based at Rugby, (Mill Road Works) and Metropolitan-Vickers Electrical Company Ltd (Metrovicks) situated at Trafford Park, Manchester. However, fierce rivalry existed between the Metrovick and BTH brands resulting in internal competition and duplicated management. This was highlighted during the Second World War in 1939, when Metrovicks and BTH became the first two firms in the world to construct jet engines (independently from each other). Following the Second World War, in 1954, AEI expanded to consist of BTH, Metrovicks, Edison Swan Electric Co, Ferguson Pailin, Hotpoint Electric Appliance Co, International Refrigerator Co, Newton Victor, Sunvic Controls, Premier Electric Heaters, Siemens Bros (1955) and Birlec (1954). In 1959 AEI decided to remove the familiar brands of BTH and Metrovicks and consolidate both as AEI resulting in internal problems and a fall in sales and market value. However, AEI acquired a variety of companies from 1959 to 1967, these included Associated Insulation Products, W. T. Henley’s Telegraph Works Co (1958), and London Electric Wire Co and Smiths (1958), Submarine Cables, Hackbridge Holdings Ltd., The Lancashire Dynamo and Crypto Ltd., W.T. Avery Ltd., Henley and Schreiber. The General Electric Company bought AEI in 1967.

Tillotsons was a publishing firm based in Bolton, Lancashire, founded by W.F. Tillotson. It remained in the Tillotson family until it was sold more than a century later. The company owned a number of weekly newspapers in the county, starting with the Bolton Evening News, launched in 1867. Other titles included the Bolton Weekly Journal and District News and the Stretford and Urmston Journal, published from 1961-1984. In 1873 W. F. Tillotson established Tillotson's Newspaper Fiction Bureau. This branch of the business quickly became one of the leading suppliers of fiction to magazines and local newspapers in Britain and internationally. The company included many prominent authors of the time, including Thomas Hardy. Tillotsons famously chose not to publish his novel, 'Tess of the d'Urbervilles', though they remained on good terms with Hardy and later published 'The Pursuit of the Well-Beloved.' In 1971 St Regis Paper Company of New York acquired Tillotsons Ltd.
