Presentation Of Inventions

Presentation of inventions *Thermical catcher The invention refers to an auxiliary equipement, situated above the burner of the cooker, for improving the heating efficiency when making the food or in others activities of housekeeping. The vessels for heating can be placed either on the kitchen range of the thermical catcher, either can be partially or totally introduced inside it, been heated simultaneous, in varied thermic conditions, controlled through the flow capacity of the fuel at the burner. *Solar catcher The invention refers to an solar catcher which provides the concentration of the solar radiation, it’s conversion into thermical energy and it’s storing by heating the water in a tank with thermo-isolating walls. The invention is composed, principally, by a tank filled with water, with a reflecting inside surface with parabolic shape or a spherical shape, which concentrate the solar radiation on a thermo-absorbing collector placed in the focus. *Threaded assembling with safety element The invention refers to an efficient dismountable assemblig, which beside the screw and screw nut ,has a piece with trapezium shape which , by pressing, prevents the dismounting. *Device for sustaining the nails when is introduced in wood Is made by two pieces with an central canal, which are serried on the nail with the help of a ring-shaped piece *Magnetico-machanical locker The device has two stable positions and is used for locking the doors, gates, drawer . It is composed by a magnetic round disc which, by turning at 1800, operate simultaneous, in same direction, over the two magnets placed on a moving frame, slided on the base piece, so that is made the passing of the locker between the two states of equilibrium. *Electrochemical writing board Is made by a dielectric base on which are attached two electrodes- first made by metal, and the other by semi-conductor glass, separated by a porous material, impregnated with nitrate of potassium and phenolphthalein or any other substance capable of producing cromatophores ions by electrolysable dissociating, used for electrochemical registration of the information with the help of a inscribe device connected at a electric source of low voltage. *Set of construction elements The invention refers to construction elements with various configurations and adapted profiles for tight unite, having included thermo-isolating materials or having internal vacuum spaces which provide a better thermical and phonical isolate. *Sprayer manualy acted Is made by a container with flexible walls, which, by successively compressing and relaxations, allows putting under pressure the inside liquid, evacuated by a nozzle outside, having a shape of a fine drop. *Thermo-isolating pipe Is made by a central pipe and an outside cover, between which is a vacuum space, necessary for thermical isolating during transportation of the fluids at different temperatures. *Thermo-gravitationaly engine The invention reffers to an thermo-gravitationaly engine, for mechanical actings, of smalls or mediums powers capable of using smalls differences of temperatures. Is composed by a cylindrical stator, with two chambers with theromoisolants walls , on the same axis with a cylindrical rotor, equipped on the inside surface with some bolws disposed longitudinal with the openings in same drection. The mouving of the rotor, heated disuniformly by the stator, is provided by the mechanical couple produced by a volatile liquid which is vaporized in the warm area and is condensed in the bowls which are passing on cold areas. *Toy actioned magnetic The invention refers to a toy used for fun and for stimulating the imagination of the childrens, which imitate approximately the moving of an animal. For transforming the rotation movement – if an compressed arch of clock or of an electrical engine of low power – in aggregate continuous rectilinear movement , the toy has an rotative magnet which interact with two other magnets, lineary disposed inside the deformed body , solidary with the legs of the animal, which prop up on the wheels with unique way of movement, allowed of the notched wheels mechanism . *Device for spalshing Is made ,principally, by an aggregate for putting under pressure the liquid of an reservoir and and the centrifugal device for spraing, acted manually or mechanic, which assure a radius of action of tens of metres depending on the height where is situated. *Electric devices for command with contacts The invention refers to an electric devices for commutation or breaking off the connection with the sources of voltage, with reduced electric resistance of contact, which is safe and has long duration of running, because of the supplementary magnetic force of pressing the elastic lamellas on the conductor pieces arranged linear or circular on a support made of an electro-non-conducting material. *Electro-magnetic pomp with flexible walls The invention refers to an electro-magnetic pomp with flexible walls, smooth or corrugated, which are changing their bulk, by compressing and relaxation under the action of the interaction forces between two electro-magnets supplied by a source of alternative current through a frequency convertor.
