Hard static balancing machine

摘要

A vertical static balancer incorporating novel methods for workpiece support and pivoting, restoring force spring placement, and means for transmission of motion and force therebetween. A single-element flexure pivot provides workpiece support while permitting near frictionless tilting movement around a vertical axis. Restoring force springs, separate from the pivoting function, are interchangeable to readily alter machine capacity. A rigid tubular member transmits unbalance effects from the workpiece to springs and displacement transducers attached thereto. Simplified electrical circuitry enables data to be transmitted from panel controls to a digital computer by means of a single conductor.
