Autogyros (Brief historical overview)

The autogyro (after Latin “autogyro”, that is, self-revolving) was invented in 1920 by Spanish engineer Juan de la Sierva. The autogyro is a flying vehicle heavier than air, with lifting capacity originating on the lifting rotor revolving freely under the action of running-on air flow passing through the lifting rotor disk, and the thrust is created by the power unit. Specifically, it ensures reduction of the take-off and landing speeds, take-off and landing runs.

“Russian Swings”, a fundamentally new technology of loose materials moulding

Application: compacting, employing zoned actuation technology, of solid loose materials (earth, soil, crushed stone, sand, concrete and bituminous concrete mix, coal and ore fines, ceramic, refractory, metal powders, saw dust, seeds) and obtaining of moulded products with dense ordered structure and improved mechanical characteristics.

Interrupted normobaric hypoxitherapy (INH)

INH is a method of treatment, prevention of diseases and rehabilitation of the organism by way of breathing gas hypoxidal (with reduced content of oxygen) mixtures in an interrupted mode at normal atmospheric pressure.

Water ozone treatment

The first pilot-industrial plant for drinking water ozone treatment was tried in 1898 in the town of Saint-More (France), and as early as in 1907, the first plant yielding ozone treatment of 22,500 m3 of water from the river Vassubie per day, to provide for Nice needs, went into operation.
