A shaking system for a harvesting head used in picking fruit from orchards has a fruit separating assembly with a lower subassembly and an upper subassembly. The cooling system has a plurality of spaced apart circularly configured cooling lines arranged in parallel planes that are perpendicular to the shell central axis and that are in thermal contact with and that run around the back surface. Soldering tabs extend beyond the plug-connector elements and are provided for electrically contacting the shield plates. Part of the evanescent fields of light propagating in the fiber is reflected at each of the surfaces, giving rise to the sensor output. Extended elution of these agents may also be accomplished in order to tailor the therapy to the patient. The dissolution chamber is much shorter in height than the conventional tower dissolution chamber, and ensures a high degree of dissolution of ozone in water and, consequently, a high degree of oxidation of organic and metal impurities to a final oxidation state.
