Abstract: An apparatus and the method thereof comprising two floating devices of different size operating in tandem. The floating devices of the same design have their respective ends made from materials of different densities to keep the devices in submerged state when put in a liquid-filled container. An automatic revolution of the floating device is achieved when the balancing status of the larger floating device is tilted by the smaller floating device.

Abstract: When the load of a movable object is applied on to a platform of the invention it will create a counter force to the original point of application by means of specifically arranged mechanical devices. With such action the platform turns into an inclined surface to provide an automatic moving force for the movable object without requiring any outside power source except for the force of gravity.

Abstract: The present invention made use of the wet and dry type thermometers principle to obtain an improved evaporative condensing unit, both in term of thermal efficiency and in the operating cost, by utilizing normal and therefore still unsaturated air from the surrounding atmosphere in the cooling of the refrigerant fluid.

Abstract: Floating structures are made to carry load up to their design loading capacities without the risk of being capsized or damaged, wherein the improvement comprises the method and apparatus for diverting all or part of the initial load to other area(s) of the structure by means of a hydraulic and/or spring action between two or more floating or resilient means that were installed under the structure.

Abstract: The water heater modified from refrigeration machine or air condition is constructed by adding an apparatus for heat accumulation by means of water parallel to the condenser of the original system, this modified system can be controlled to work as an ordinary refrigeration machine or air conditioner, or to work simultaneously both as a refrigeration machine or air conditioner and also as a water heater, the advantages of this water heater are that it is obtained by a simple modification to the existing refrigeration machine or air conditioner, it can be installed at a remote distance convenienty without decreasing the effectiveness and the safety of the original system, and it can be operated to supply hot water without any additional energy consumption from what being consumed for supplying cold air by an original refrigeration machine or air conditioner itself.

Abstract: The losing of a huge amount of energy is overcome by a method and an apparatus for heat accumulation from refrigeration machine of the present invention. The apparatus comprises of two sections. The first section is the smalled diameter heat carrying fluid tube inserted inside the larger diameter refrigerant tube of the condenser, the second section is the expanded cross sectional area refrigerant tube enclosed inside the heat carrying fluid tube. By replacing the conventional refrigerant tube of the condenser by the first section of this invention, by connecting the second section of this invention between the compressor and the condenser of the conventional refrigeration machine, and by feeding the heat carrying fluid into the two heat carrying fluid tubes connected in series in the direction opposite to the direction of the refrigerant flowing inside the refrigerant tube of the refrigeration machine, the heat carrying fluid with its temperature high enough for an industrial use can be obtained.
