US Patent 3,865,148, granted Feb. 11, 1975 to Sulzer Brothers Limited, describes a jacquard machine in which lifting hooks are shifted between two alternately moving draw knives. A sensor and a pivoted lever, together with a flexural control element (magnetostrictive or electrostrictive) that bends under an applied field, control the shifting. The patent explains the problem with earlier selector and transmission mechanisms, gives the objects of the invention, and walks through the operating cycle of a double-lift open-shed machine on a loom. It includes three sheets of drawings (Figs. 1-4) and 10 claims.
