    Abstract: An apparatus for measuring angles of displacement between human femur and tibia leg bones to determine the stability (stiffness and laxity) of a knee joint has structure and instruments for checking upper and lower leg bone alignment, angulation and degree of relative lateral displacement. A platform is provided to support and secure a human torso about its hips while auxiliary inner and outer coacting frame support structure adjustably secures the leg bones. Sensing and indicating instruments associated with the coacting frame structure and an auxiliary detachable support frame contact the leg and foot to give a reading on leg and knee stability as the lower leg bone (tibia) and the foot are selectively placed at various angles while predetermined side loads on the tibia are simultaneously applied.

    Abstract: An improved mechanical-over-hydraulic steering apparatus capable of providing automotive-type steering includes a steering wheel driven input control member, right and left turn control valves, and first and second actuators mounted for rotation along an axis common with the input control member. Each of the actuators has a cam operatively associated with a cam-following roller assembly that operates the respective control valve. The vehicle has a cross drive mechanism, and the steering apparatus includes an over-center variable displacement steering pump and associated displacement control controllably operated by first and second pilot lines connected to the right and left turn control valves. The steering pump controllably and bidirectionally communicates fluid to a steering motor for the steering input to the cross drive mechanism.
