1935 à 1970
A subsidiary company of the Société de Commentruy-Fourchambault et Decazeville which in 1954 became the société Métallurgique d'Imphy. It was created primarily to manufacture the instruments devised by Pierre Chevenard (1888-1960) for researches carried out in the laboratories of the company on metal alloys, particularly concerning ferro-nickel and nickel-chrome. Chevenard, whose researches follow on from those of Charles-Edouard Guillaume and in collaboration with whom many of them were undertaken, was the first président-directeur-général of the company, and later Honorary President. Among the instruments he devised are direct reading dilatometers, differential recording dilatometers, a torsion oscillometer for the study of thermo-elasticity, used in collaboratioin with Guillaume for the study of Elinvar, a thermo-magnetometer which automatically drew the curves representing the variation of degree of magnetisation according to temperature, a thermo-balance, various heat machines for the study of metal fluidity, and micro-machines for the study of flection, filing and traction on miniscule metal fragments. In 1970 ADAMEL was amalgamated with the Lhomargy (acronym of 'Lhomme & Argy) Company, specialists in instruments for the resistance of materials, in particular paper, at Draveil to become 'Adamel Lhomargy, Essais de matériels', which company is still active in 2012.
