摘要： Device for raising weights in precision balances, such as analytical balances, in which a number of weights from the smallest to the largest are disposed substantially in a single plane and are made associated with at least two pusher raising elements mobile in a direction substantially orthogonal to the plane of the weights, the pusher raising elements being raised by programmed operating means including rotatable annular disc members and cam means provided thereon. The disc members are rotated by acting on the weighing control members of the balance.
