1. A mechanical shaft that is allowed to rotate less than 180 degrees and consists of layers of metal and anti-corrosion flexible material that has property of resisting corrosion in any gas or liquid environments, and lever and sprocket systems are attached at both ends of the shaft such that continuous rotation of the input sprocket in the liquid environment gets transmitted into gas environment via a mechanical system that consists of two special sprockets and two special levers where the input sprocket in the liquid environment rotates in counter clockwise (or clockwise) direction but has sprocket teeth only over a partial segment of circular are less than 180 degrees such that as the sprocket rotates in counter clockwise rotation, it engages with the pairing lever while the sprocket teeth contact with the sprocket teeth of the paring lever and turns in clockwise rotation as long as the teeth contacts continue but when the teeth of the sprocket run out, the disengagement occurs and immediately, the weight installed inside the gas environment pulls a string and rotates the output lever in the gas environment in counter clockwise as well as the input lever in the liquid environment and this process repeats as the input sprocket in the liquid environment keeps rotating in the counter clockwise rotation, where since the amount of rotation is less than 180 degree, it enables the layers of metal and anticorrosion flexible material to completely block the liquid penetration into gas environment, and the amount of rotation of the lever inside the gas environment and its direction are the same as the amount of rotation of the lever and its direction in the liquid environment, and the repetition of counter clockwise rotation and clockwise rotation of the lever in the gas environment generate continuous clockwise rotation of the output sprocket inside the gas environment by a means of rotational tooth assembly installed on the lever inside the gas environment, where the rotational tooth assembly consists of tooth, levers on both side of a hinge, lever rotation stopper, and weight to pull back the tooth to original positon whenever possible, and thus the rotation energy transfer takes place. |
