In 1915 the American company Powers Tabulating Machine Company established European operations through the Accounting and Tabulating Machine Company of Great Britain Limited, in 1929 renamed Powers-Samas Accounting Machine Limited (Samas, full name Societe Anonyme des Machines a Statistiques, had been the Power’s sales agency in France, formed in 1922).

In 1952, Underwood, the typewriter manufacturer,  acquired the American punched card tabulating equipment assets of the British Powers-Samas company.

Unlike IBM equipment Powers-Samas equipment was entirely mechanical. Rectangular holes in punched cards were converted into electrical signals as they passed under a row of wire brushes. Pins that could drop through round holes in cards were connected to linkages and their displacement when a hole was present actuated other parts of the mechanism to produce desired results.”
