Abstract: An apparatus for filling a container with a liquid to a predetermined weight which utilizes a scale which generates a control signal which is based on the weight of liquid within the container, a control valve such as a ball valve having a valve element which permits a selectively variable flow rate through the valve, an actuator which is operatively connected to the control valve to vary the position of the valve element and thereby vary the flow rate, a valve positioner to control the operation of the actuator/valve in response to a calculated positioning signal which is related to the control signal and which is generated by an interface arrangement operatively connected to the scale and the positioner.

Abstract: A materials handling and weighing apparatus having a platform movable in a rectangular motion for transferring a work piece in stepwise fashion along a conveying path, the apparatus having a work piece escapement mechanism whereby work pieces are sequenced onto the movable platform one at a time without interference from a succeeding work piece, the weighing apparatus employing load detecting cells upon which the work piece is deposited during a cycle of the movable platform.
