Abstract: A calibration stand for electrical torque transducers capable of applying torque loads on the order of 300,000 inch-pounds (33,900 newton-meters) has deadweight loading applied through a thin flat high carbon steel hangar strap. The hangar strap contacts the end of the load moment beam on a curved surface having a constant radius of curvature equal to the distance of the surface from the beam torque axis. As the transducer deflects under increasing deadweight loading on the hangar strap, the load moment beam rotates and the strap remains vertical and contacts the loading surface along a moving tangent point which has a precise constant distance from the torque axis for providing a high degree of accuracy.

Abstract: Disclosed is a speed controlled fluid pressure regulator that is adapted to provide a fluid pressure control signal for use in a variety of control functions in response to changes in rotational speed of an object such as a rotating component of an internal combustion engine. The regulator is controlled by a speed biasing mechanism that utilizes a counterbalancing arrangement between a biasing means and a component that is moved by a centrifugal weight assembly in response to changes in the rotational speed of the object being monitored to position a valve of the regulator with a high degree of sensitivity which in turn enables the regulator to provide the output fluid pressure control signal from a fluid pressure source in a highly effective manner.
