WO/2015/177804 A LEVERAGE ASSEMBLY FOR ENERGY GENERATION||WO||26.11.2015|
||PCT/IN2014/000509||RAJAGOPAL, Ramesh ||RAJAGOPAL, Ramesh |
The present invention relates to various aspects of leverage assembly for energy generation. According to one aspect, the leverage assembly comprises at least one first order lever having an effort arm and a load arm, where at least one weighted body is fitted to the extreme end of the effort arm and positioned in opposite to the end of the load arm. At least one mounting table has a fulcrum on its top side and a slot to pass-through the lever load arm into it, where the table is mounted on a base plate for being reciprocally actuated in back and forth movement. Power receiver assemblies are positioned adjacent to the mounting table to be in operative contact with the end of the lever load arm at the time of lever oscillation. The first order lever is pivotably mounted onto the table through its fulcrum in a frictionless manner in such a way that when the table is being reciprocated, the lever effort arm along with its weighted body is oscillated on the fulcrum at a desired oscillating angle, which simultaneously generates a multiplied force, at the end of the lever load arm, that is directed to operate the power receiver assemblies for energy generation. Thus, such leverage assembly generates efficient energy with the oscillating first order lever arrangement in an easy, reliable and cost effective manner.

||PCT/FR2015/000102||RADOUL Christian ||RADOUL Christian |
The present invention relates to a device for perpetual motion brought about by the rotation through Archimedes upthrust, amplified by the lever effect, of two rectangular parallelepipeds fitted in a cross shape on a central shaft dipped into a liquid. The movement of two boxes M1 and P1 or M2 and P2 in each of the parallelepipeds of different volume, different volumetric mass but virtually equivalent weight that are connected together by a cable passing over pulleys makes it possible to create an air pocket to which Archimedes upthrust is applied, causing the overall system to rotate under the lever effect. A generator producing electricity will be installed on the rotary shaft of the system.
