Abstract: A wet-to-use organic cell battery includes a container filled with an electrolyte that is made from organic materials, an electrolyte solution, such as water, can be repeatedly added into the container to mix with the electrolyte, and two electrodes electrically connected to a mixture of the electrolyte and the electrolyte solution, and insulated from each other. Thus, the organic cell battery of the present invention has the advantages of being able to preserve the electrodes from consumption and rustiness, being refreshable, and being benign to environment and public health.

Abstract: An automatic tube bending machine, in which, an electric motor is adapted to drive a speed reduction multiple-pulley system which in turn powers a synchronous intermittent feeding device to feed tube pieces piece by piece into a moulding seat from a storage rack, the same pulley system also actuates a flywheel, and this flywheel drives a gear system that then spins a crank shaft having two symmetrical crank arms, which in turn move two face to face arranged splines, then this two splines drive their respective gears engaged therewith, and these gears in turn actuate two L-shaped outward bending moulds to rotate; at the other end of the same crank shaft, it is provided with a bevel gear; engaged with another bevel gear system so to drive another crank shaft, in such a manner, these two crank shafts rotate synchronously in opposite directions; in the meanwhile the latter crank shaft drives a sliding seat, on which is provided with an inward bending mould, located in the opposite side of the two L-shaped opposit
