— Air circulation due to difference of density resulting from a difference of temperature.

— Heat transmission by movement of a fluid caused by density differences due to temperature variations.

— An air cooler depending on natural convection for air circulation.

— A condenser cooled by natural circulation of atmospheric air.

— a) Cooling a fluid by natural convection over the cooling surface. b) Cooling a space by means of air cooled by natural convection.

— Water cooling tower in which air circulation is obtained by natural convection.

— To supply very fine water spray or steam into an air stream or enclosure.

— A type of roller bearing in which rollers of small diameter are used.

— A valve the obturator of which is a stem ending in a conical point which mates with a corresponding valve seat.

— Temperature above which the magnetic order in antiferromagnetic substances vanishes: below this temperature, atomic magnets are parallel to the direction of antiferromagnetism; above this temperature, they are orientated at random.
