The invention relates to a drink containing calcium ions, potassium and carbohydrates, in the form of sugars and electrolytes, which are lost as a result of heavy sweating, said drink also containing water, flavouring agents and preservatives. The drink is characterised in that it quickly adds calcium ions to the blood stream.

Device for grilling food, which comprises three parts (1, 6 and 9) arranged one on top of the other and dismantlable, such that the first part (1) is the part with a free upper surface on which the food to be grilled is placed, the third part (9) is the part with its underside in contact with an external heat source, and the second part (6) is located between the first (1) and third (9) parts. Furthermore, the three parts (1, 6 and 9) consist of metal sheets that are flat and thin with respect to the size thereof, such that the first part (1) and third part (9) are of any shape, as long as they are identical, and the second part (6) is of circular shape with a diameter that is smaller than the size of the first (1) and third (9) parts.

The use of disposable materials, a strip of disposable material, made from Hidrotela, gauze, cotton or other, manufactured in the same way as a light duvet measuring fifteen centimetres wide by seventy-five centimetres long, containing three strips of newspaper ten centimetres wide by seventy centimetres long, this latter material being capable of insulating heat in the human body, is submerged in a concentrate of camphor and eucalyptus in quantities of fifty percent camphor and fifty percent eucalyptus, before being dried industrially. This “scarf” is used by wrapping it around the neck of the person wishing to protect their throat, upper chest or thorax from a cold environment,  in extreme cold.

Device for generating and transmitting heat capable of operating with fuel in any physical state that includes at least one cylindrical combustion chamber (9) divided into a lower section (11) and an upper section (12) of variable height, a pressurized air chamber (26) arranged below the lower section (11) of the combustion chamber, and a plurality of air injectors (14). The device is characterized in that the air injectors (14) are supported on a flat ring (43) and set in a second flat ring (52) and in that it also includes a set of replaceable parts (A) arranged in the free centre of both flat rings (43 and 52) and whose specific configuration depends on the physical state of the fuel being used. Furthermore said set of replaceable parts (A) includes at least one central air injector (16) located in the geometric centre of the unit.

The invention relates to a disposable piece of material such as Hidrotela® and/or gauze or cotton, combined or otherwise, all of said materials being absorbent and disposable, cut freely according to the dimensions required by the user, and having an opening at the centre thereof, measuring approximately four centimetres and containing a T-shaped metal or wooden structure with a horizontal base, to be used for cleaning floors. Said disposable material has been previously submerged, according to a complete submersion process, in a mixture of detergent, lye, and liquid wax with an aromatic agent and water, and duly dehydrated, ensuring the cleaning, asepsis, disinfection, and polishing of floors and structures.

The invention relates to a system for decontaminating contaminated domestic wastewater, comprising the efficient elimination of soluble and insoluble organic compounds and microorganisms of fecal, food, cleaning or other origin found in one or more houses. The system is used for the treatment and decontamination of water and the environmental recycling of same, as well as the residues resulting from the treatment, namely gases and dehydrated sludge. The system is made up of tanks or containers and other plastic materials used to form the constituent apparatuses thereof and is installed underground, such that the users cannot smell any unpleasant odours around the houses and such that the users do not have to perform any significant maintenance operations. This technology can be replicated for the decontamination of water containing biodegradable organic waste of animal, vegetable or industrial origin.

The inventionis a Mechanism for deactivation of cylinders in internal combustion engines summarized as the cancellation of the functioning of one or more cylinders in an internal combustion engine, by means of the release and locking of the springs which close the inlet and exhaust valves in order to keep them closed and open respectively and simultaneously. The closed inlet valve prevents the intake of gases or fuels from the inlet manifold and the open exhaust valve prevents compression of the gas contained in the combustion chamber of the deactivated cylinder, so that the latter avoids fuel consumption and compression efforts during periods of low demand on engine power.
