Abstract:
A system and a method for prevention of adhesion of marine organisms to a substrate contacted with seawater are provided. The system comprises a generator (120, 220) for producing an electrical signal (150) operating in desirable frequencies in which the marine organisms can be chased or killed, said generator (120, 220) having at least two output connectors (122, 124, 222, 224), means for oscillating and propagating the electrical signal (150) along a surface of the substrate, said means being adapted to make electrical connection with the at least two output connectors (122, 124, 222, 224) of the generator (120, 220) and being submerged in seawater, and an electric power source (110, 210) connected to the generator (122, 124, 222, 224) for applying a selected voltage to the generator (122, 124, 222, 224) to produce the electrical signal (150).

The device containing a transformer (1) with an attached rectifier (2), a filter condenser (6) connected to the rectified electricity and a voltage stabilizer Zener-diode (3). The device containing an integrated circuit (15) generating square-wave frequency is connected to the stabilized power supply with a frequency adjuster unit consisting of a condenser (8) and resistors (13, 14) attached, and wires (A, B) coiled on the water pipe are connected to the outlets of the device.
Abstract:
An electric pulse generator supplies a device which creates an electromagnetic field in a liquid in order to reduce the formation of salt incrustations on a wall in contact with said liquid. The generator is equipped to produce successive bursts of signals (Fx), each burst comprising several signals (40), each signal having the form of a wave with a front flank (401) which rises almost immediately from the base level (V0) of the signal up to a first peak amplitude (V1) and a rear flank comprising a descending portion (402) between the first peak amplitude and a second amplitude (V2), a plateau (403) of substantially constant level (V2), and a second portion (404) between said plateau and the base level (V0) of the signal. The device is used in all installations in which a wall is in contact with a liquid.
Abstract:
The invention relates to an apparatus for the treatment of a fluid, such as tap water or fuel, by means of electrical induction, comprising one or more printed circuit boards provided with an antenna that receives signals from a steering unit and transforms same into inductive signals acting upon the fluid to be treated. The printed circuit board comprises holes positioned according to a pattern comprising one or more blocks, each block comprising one or more rows wherein the holes are positioned at regular distances from one another, and wherein the blocks each are displaced over one another.
Abstract:
Water in a recirculating hot potable water system 110 is treated by power pulses, by placing a coil near the water and providing to the coil an AC power source. The power source is connected in a first loop with the coil and a switch during at least a portion of a first half-cycle of the AC power source period. The switch is opened during a second half -cycle, during which a subroutine of producing at least a first ringing pulse in the coil assembly is performed. The water is treated chemically and by the power pulses. An improved water system has a water heater 112 and a circulation line 116 providing a flow loop. There is a tap 124 for diverting circulating water through an external loop and there is a pulsed power water treatment apparatus 122 mounted on the circulation line. A chemical treatment apparatus 126 is periodically connected to the tap.
Abstract:
An apparatus (1) subjects water to waves from an RF plasma. This allows continuous production of 'activated water' characterized by cluster sizes below about 4 molecules per cluster, water having pH below 4 or above 10, or water having ORP of less than -350 mV or more than + 800 mV. The basic frequency of the plasma is preferably between 0.44 MHz and 40.68 MHz, and the plasma is preferably modulated at a frequency between 10 kHz and 34 kHz. Flow rates typically range from 20 l/hr to about 2000 l/hr. Activated water can be used for many purposes, including antimicrobial cleaning of worktable, floor, wall, knife, transport and other surfaces, for example, in meat processing facilities and hospitals.
