An ocean wave energy converter (WEC) uses one or more buoyant elongated float(s) mechanically linked to a motion-stabilized, controlled-submergence depth frame by either swing or lever arms or down-sloping tracks defining and orienting the motion of the floats relative to the frame to capture both heave and surge wave energy forces. The submerged depth of the frame and attached float(s) is adjusted for optimal wave energy capture or submerged sufficiently to fully submerge the float(s) during severe sea conditions. The elongated float's compliant wave-impacting forward wall combined with total submergence during severe sea states allows the elongated float(s) to self-orient parallel to oncoming wave fronts to intercept and capture maximum wave energy per unit of WEC volume, weight and cost.

A propeller control generates a once per revolution (1P) blade thrust variation through cyclic pitch of rigidly mounted non-flapping propeller blades. The resultant shaft bending moment is used to provide aircraft attitude control. Axial translation of a pitch change assembly including a pitch change yoke along an axis of rotation drives a pitch link attached to each propeller blade to collectively change the propeller blade pitch angle. The pitch change yoke includes a translating pitch change yoke portion and an articulatable pitch change yoke portion. Deflection of the articulatable pitch change yoke portion changes the pitch change effect of each pitch link as a function of its angular position such that a sinusoidal pitch angle is superimposed on normal pitch angle. Cyclic pitch change actuators deflect the articulatable pitch change yoke portion in any angular direction while the linear deflection of the cyclic pitch change actuators generate the magnitude of the cyclic pitch.

The mold composed of base, sleeve and torsion nut is adopted in the invention. Opening circular ring sample is placed on the base; next, sleeve is loaded and pressed; then the torsion nut is mounted. The mold with sample being loaded is placed on the platform. Using pressure acts on the sleeve vertically. When pressure reaches to a prearranged value, the pressure load is kept, and torsion nut is twisted. Thus, under action of shearing force, the material generates even plastic deformation. Afterward, under action of friction force of inner and outer toroid mold drives torsion so as to generate shearing deformation to treat material. The method generates larger amount of deformation in theory, and magnitude of amount of deformation can be controlled.
