• the present method allows the user to clean and dispose of the goods that were in use, and to take care of them In order to restore the protective protection, small amounts of inhibition are repaired. Decreases in 4-6 times the result of the inhibition. For the sake of better understanding of the invention, the following methods of implementation are claimed. Examples I.
• the pump After using a fixed device with a length of 25 km for the inlet of the inlet to the inlet, the pump will be pumped and pumped out.
• the pressure of the pressure in the water is increased by a factor of 0.1 and the pressure is higher than , 3 ⁇ Pa). Changes in pressure in and over services are subject to a loss of service, 15 flowing through a device gap.
• the appliance After the appliance is in the camera, it is removed from the appliance. Removes dazlenie from piezoelementov.
