Balance for determining the weight percentage of an extracted component with respect to the total weight of a test material

摘要

Balance for determining weight percentage of an extracted component with respect to the total weight of a given material, comprising two load-receiving units and two movable rigidly connected balance weight interconnected by flexible ties that embrace a drum. As the drum rotates, the load-receiving units and the balanceweights move simultaneously along the beam in opposite directions until the beam is set in equilibrium, at which a vernier position on a linear scale indicates the sought percentage.
