Abstract: A vibration isolation arrangement, for example for supporting a stretcher in an ambulance, comprises a lever (16) which extends between a base structure (6) and a support frame (4). The lever (16) can pivot about a fulcrum (30) and is acted upon by a spring (28). The fulcrum (30) is displaceable by an actuator (32) along a guide (34). Such displacement not only varies the stress of the spring (28), but also alters the moment arm (h) between the spring (28) and the fulcrum (30). When raising the support frame (4) to a predetermined level, the mechanism automatically adapts to the load on the support frame (4) to provide a constant natural frequency for the system, regardless of the weight of the patent being carried.

Abstract: A spring return valve operator for actuating a valve is comprised of a spring return actuator which is loadmatched to a valve load and extracts a large fraction of its spring energy storage capacity, and a controlled actuator which is load matched to the valve load and the spring return actuator retensioning load. Within the spring return actuator, the output of nested torsion springs is transformed into various torque outputs, particularly constant torque outputs and increasing torque outputs. Spring output is transformed by eccentric spool and flexible element mechanisms or by four bar mechanisms through changes in leverage produced by varying torque arms. The output of a controlled actuator can be transformed into torque outputs which are decreasing, increasing, etc., using eccentric spool and flexible element mechanisms or using four bar mechanisms in order to produce a loadmatch to the valve load.

Abstract: A device for connecting a helical compression spring to the trailing arm in the wheel suspension of a motor vehicle. Bending stresses on the spring are prevented by supporting it on the trailing arm through a support that is mounted in a bushing rigidly attached to the trailing arm in such a way that the support moves freely around predetermined angle to the normal to the plane of support on the trailing arm. In one embodiment that is especially simple in design the wire at the end of the spring that faces the trailing arm spirals in as far as the center line of the spring, the end of the spring wire is bent at a right angle and extended axially out of the spring, and the end of the spring wire functions in itself as a support, the face of the end of the wire resting on a ball positioned in a bushing.

Abstract: Helical spring is mounted between two lever arms which are hinged together at one end; the spring is attached at its ends to disks which are pivoted rotatably to the lever arms, the spring axis being parallel but eccentric to the line joining the two pivot points. Rotation of the disks moves the spring closer to or farther from the hinge point, effectively changing the elastic constant between the distal ends of the lever arms, which are points of attachment to a vehicle chassis and to its running gear, respectively. Spring position may be adjusted by worm drive operated manually by crank or by motor controllable by driver from instrument panel; this adjusts vehicle springing to various vehicle loads.

Adjusting position of the spring means and a fulcrum means along the length of the lever assembly adjusts the support effectiveness of the weak spring means as well as the direction of its effort imparted to the support rod.
