Abstract: A system is described which utilizes two perpendicular four-bar linkages coupled by a common plate to provide a translational-free flexible suspension having two rotational degrees of freedom about a desired point. One of the four-bar linkages is secured to a stationary "ground" structure, and the other linkage is attached to the object to be supported, such as a mirror. In one embodiment, two links of each of the two four-bar linkages are constructed from spring steel flexure elements which are rigid in all directions except about the rotational axis. The flexure elements thus comprise "revolute joints". Because the flexure elements function as spring hinges, no friction is encountered when the suspension is displaced or "pivoted".

Abstract: In a torsion spring the spring action is a result of the relationships between the torque applied in twisting the spring, the angle through which the torsion spring twists, and the modulus of elasticity of the spring material in shear. Torsion springs employed industrially have been strips, rods, or bars, generally termed shafts, capable of being flexed by twisting about their axes. They rely on the variations in shearing forces to furnish an internal restoring torque. In the torsion springs herein the restoring torque is external, and therefore independent of the shearing modulus of elasticity the torsion spring shaft. Also provided herein is a variable stiffness torsion spring. This torsion spring can be so adjusted as to have a given spring constant. Such variable stiffness torsion springs are extremely useful in gimballed payloads such as sensors, telescopes and electronic devices on such platforms as a space shuttle, a space station.

Abstract: A thin sheet of metal is patterned, folded, and joined to produce an array of compression springs, each of which exhibits constant force characteristics over a useful range of deflections to allow the array to apply nearly constant specified forces to closely spaced items which may be of varying size or height. As the springs are loaded from a relaxed state, the rate of force increase per unit of increased deflection is initially high, tapering off to nearly zero force increase with subsequent increases in deflection. This region of minimal force increase per unit of increased deflection (i.e. a "near constant force" band) extends over a useful range of deflections. The springs are self guiding and balanced, producing no lateral force on a perpendicularly applied load.

Abstract: A reflow solder head has its heater bar (30) mounted so as to cause the heater bar to contact a tilted reflow surface (50) and align itself with the tilted surface without tip skid. The heater bar is mounted to its movable drive ram (40) by two independent pivots (36,42), both nominally positioned on a line normal to and in the center of the heater bar itself. The first pivot (36) closer to the heater bar allows the heater bar to rotate about its first point of contact (54) with the tilted reflow surface. The second pivot (42) allows lateral movement of the first pivot (36) without tip skid during the rotation of the heater bar about its first point of contact. This double pivot mechanism eliminates the tendency of the heater bar to skid along the reflow surface.

Abstract: A suspension system for linear reciprocating device which allows a relatively large axial stroke while also providing long life and high torsional and radial stiffness. The system consists of a grounded ring to which pairs of substantially coplanar cross straps are connected about an axis of symmetry around the ring. The midpoints of the straps are attached to the reciprocating device. In operation the flexing of the straps in combination with the distortion of the grounded ring allows for a greater axial stroke within a smaller perimeter than using flexing straps alone. This allows the suspension device to be utilized in a much smaller area providing further advantages in application.
