Abstract: The present invention is an aerodynamic sunshade that has a flat frame or rack made up of a series of radial or angular rods or arms, having the outermost ends of said arms joined to the perimeter of a hexagonal kite- or arrowhead-shaped cloth, said frame or rack being supported in an eccentric and articulated manner perpendicularly from a point between the leading edge of the kite or arrowhead and a third of its main centreline by a cylindrical element, stem or mast, which is embedded either in the sand, in a concrete base or a handle, with the addition of peripheral flounces or fringes at the sides or outside edge of the cloth.

Abstract: Lifting and propulsion system for aircraft with vertical take-off and landing that consists of applying to the aircraft certain propeller engines and rotating lifting systems around the transversal shafts and near the centre of gravity, presenting pairs of stabilizing propellers, turbines or fans in counter-rotation activated by electrical motors on the tips of the wings, nose and stabilizers on the tail of the aircraft, the electrical motors are powered by batteries, supercondensators, high powered electrical generators activated by the engines and by special auxiliary power units.

Abstract: A system for bathing, showering, drying, massaging and sauna, which includes a container having a vertical arrangement, a main body, a bottom surface, a water-drainage orifice and a door for allowing entrance of a user in a wheelchair. The bottom surface is at the same level as the door in an open position. The bottom surface has a small descendent inclination towards the water-drainage orifice. The door has an edge acting as slight connecting ramp with a floor of a room in which the system is placed. The door has pawls or iron straps, which lodge and are retained in recesses formed the main body for fastening the door, and the door has magnets for maintaining the door in a closed position.

Abstract: The present invention is turbofan or turbojet assembly for vehicles, craft, aircraft and the like. The assembly includes a plurality of gas turbines, mini-turbines, micro-turbines or nanoturbines disposed in parallel. The turbines form a gondola that is a large, single turbine.

Abstract: A process for the recovery of the energy from the air in pressurised areas of aircraft that involves linking or moving air from the pressurised areas to the lower areas of the fuselage or lower surfaces of the wings, the horizontal stabilisers, and other aerodynamic profiles, along ducting and/or by discharging through multiple slots or openings flowing downward and rearward with a small inclination against the direction of the air flow, to avoid turbulence. The pressure of the pressurised cabin air conditioning is used. In other cases, it is used the pressure produced at the front of the fuselage, on the leading edges of the wings, the horizontal stabiliser or other aerodynamic profiles. Lift is increased in all cases without further energy requirements.

Abstract: The lifesaving system for buildings of the present invention includes a tubular device having opened crowns or circular radial curved crowns attached to an inside wall of the tubular device, the crowns having flexible vanes or fins through which inverted bell-shaped elements pass, the elements larger in size than the inner size of the crowns, and are braked or slowed as they move downwards, a foam rubber element added at an end of the tubular device, and an annular element having an outside perimeter forming a tapered cone and curved, and which adapts to a top of a user's chest and is positionable under user's armpits.
