  Class Definition for Class 267 - SPRING DEVICES
Spring device including a compartment or material adapted to contain a fluid to be applied to relatively moving portions of the device to reduce friction therebetween.
Device in which one of the diverse springs is a metallic member and another of the springs comprises a fluid containing compartment having a restricted or valved orifice to regulate the flow of fluid into or out of the compartment, and the flow of fluid through the orifice dampens the movement of the metallic spring.
Device wherein the panel is composed of a series of spiral springs, arranged with the axes of the spirals parallel to each other and aligned in the direction the load is received, and in which the spiral springs are of the type which receive the load in compression.

Coil spring or helical spring - a spring (made by winding a wire around a cylinder) and the conical spring - these are types of torsion spring, because the wire itself is twisted when the spring is compressed or stretched.
Spiral spring or 'clock spring' - a spring of the type as used in clocks, galvanometers, and places where electricity must be carried to partially-rotating devices such as steering wheels.
Spring washer - used to apply a constant tensile force along the axis of a fastener.

The static equilibrium between the springs 11,12 is thereby upset and the first spring 11 is also expanded, thus causing the supporting rod 8 and the plate 9 to be moved forward from the neutral position to a first position P 1, downstream relative to the neutral position N2 and the vessel's forward direction.
The first compression spring 11 is thereby compressed, with the result that the plate 9 is moved backwards, past the neutral position N2 to a second position P2, upstream relative to the neutral position N2.
A device according to claim 6 or 7, characterized in that the drive device (4) is arranged to provide the body (8, 9,10) with energy impulses with a frequency corresponding to the oscillating device's natural frequency (E).

Since no installation is required, pilots who fly multiple airplanes or rent aircraft can readily carry the device from one aircraft to another.
The device, the article said, works by interpreting transponder replies from nearby traffic, meaning that aircraft not delivering transponder replies do not generate alerts.

Stan - springs have a known restoring force and the force a spring exerts is proportional to how much its compressed/expanded.
As you apply torque the drive is attached to the ramp that applies the force (from the torque) to the spring.
At some point the force applied by the ramp is greater than the spring so the ramp is allowed to move and when it does it releases from the drive so the drive can freewheel.

The lower court granted summary judgment in favor of Traffix holding that MDI could not establish secondary meaning in its alleged trade dress because the dual spring design was functional and there was an absence of source/good recognition by consumers.
In earlier litigation, MDI argued that the springs in a very different-looking dual-spring design device fell within the claims of MDI’s patents under the doctrine of equivalents.
Traffix’s dual-spring device would have been covered by the claims of MDI’s expired patents in its earlier litigation, thus providing further evidence of functionality.
