Abstract: A method for introducing gas like oxygen, air or carbon dioxide into water, in which a water flow enriched in the gas is passed through a reaction chamber so that the flow rotates around and moves along the Longitudinal axis, a sudden pressure minimum is provided in a section of this axis where gas comprised in the flow gets collected and mixed with vapor, the pressure is increased after the minimum, whereby gas is swallowed by water so that gas molecules get bound to water molecules. The apparatus for carrying out the method comprises a closed recirculating path with the reaction chamber, the flow is maintained by a pump, and the gas is introduced in the water either by a vortex stream or by a water jet pump. The so obtained water comprises the gas in stable and bound state in a concentration exceeding normal saturation. The dielectric constant and certain physical parameters of such water differ from those of pure water.

Abstract: Therapeutic lamp emitting polarized light, comprising a housing of three consecutive parts which define a common interior space, the first part being a handle having a substantially tubular form, the second part being a dome-shaped middle portion attached to an end of the handle, and the third part being a cylindrical frontal portion attached to the middle portion, the frontal portion having an axis which forms a first obtuse angle with the axis of the handle.
