  • An optional air outlet channel 38 is provided and is attached to the lid 18 to surround the air outlet opening 34, and the air fan 36 is mounted on top of the air outlet channel 38.

  • the non-conductive housing 50 is preferably made from a transparent plastic.
  • FIG. 3 there is shown a perspective, break-away schematic view of one of the sets 22 of electrodes shown in FIG. 1.

  • the electrode holders 56 are preferably male threaded conductive rods.
  • Conductive, female- threaded mounts 58 are fixedly attached to the lid 18, for mating with the male-threaded holders 56 in threaded engagement.
  • the mounts 58 are electrically connected to the transformer 30 as shown by electrical leads 66.

  • the workings of the invention are brought about by forming an electrical circuit with the components described above, in which the circuit would not be closed except for the provision of fluid 14, preferably water having some degree of conductivity to it.
  • the conductivity of the fluid 14 is of course relatively low, making the resistance relatively high at the points where the upper electrodes 24 interface with the fluid 14.
  • the upper electrodes 24 are preferably silver wires, in which case the resistance produced by using the conductive fluid 14 to close the circuit operates to disrupt the silver electrodes 24 and cause particles of silver to separate from the electrodes 24 and enter the fluid 14 in suspension, preferably colloidal suspension. In this manner, as the silver particles are gradually separated from the upper electrodes, the fluid 14 gradually becomes a solution of suspended silver to be taken orally or topically as needed to enhance the personal health of the user.
  • the silver solution fluid 14 may of course be taken or administered in any manner desired.
  • the positioning of the electrodes 24 and 26 has significance.
  • the inventors have found that production is probably optimized by positioning the upper electrodes 24 such that their distal ends 24b reside above the surface 16 of the fluid 14, and with the lower, center electrode 26 being at least partially submerged within the fluid 14, if not fully submerged.
  • the lower, center electrode 26 is preferably a planar conductive member, thereby providing a large amount of surface area to reduce the concentration of electrical resistance produced by it.
  • the three electrode holders 56 are preferably disposed in a row along a relatively straight line 70, and it is preferable to position the lower, center electrode in a substantially perpendicular orientation with respect to the line 70.
  • Non-conductive handles 72 are securely attached to upper end of the electrode holders 56 to enable users to turn the electrode holders 56.
  • the handles 72 preferably extend through the housing 50 such that all exposed portions of the electrode holders 56 residing above the lid 18 are contained within the housing 50 to thereby prevent unsafe human contact with such exposed, electrically live portions of the electrode holders 56.
  • the distal ends 24b of the upper electrodes 24 are preferably maintained above the surface 16 of the fluid 14 at a distance within a range of 0 inches to 1 inch, and more preferably within a range of 0 inches to 3/16 inch. It will be appreciated that the length of the silver-wire upper electrodes 24 becomes gradually reduces as silver particles are disrupted and separated from the distal ends 24b, thereby increasing the distance by which the distal ends 24b reside above the surface 16. When the distal ends 24b are too high above the surface 18, "arcing" occurs, which is accompanied by an electrical arc that is produced between the distal end 24b and the surface 16 of the fluid 14.
  • Applicants have discovered the colloidal silver produced while arcing occurs for significant periods is at least aesthetically contaminated, and may by contaminated in other ways as well.
  • Suspended silver solution produced by the methods described herein when utilizing a clear, clean water as the fluid 14, retains a clear, sparkling and desirable appearance when produced without significant periods of arcing.
  • the resulting solution takes on an unpalatable, translucent appearance exhibiting a gray or dark green color.
  • Applicants have solved the problem of arcing by providing the male-threaded electrode holders 56 disposed in threaded engagement with the female-threaded mounts 58.
  • the apparatus 10 may simply observe the position of the silver-wire upper electrodes 24, and a particular electrode 24 becomes too short, the user can simply twist the corresponding handle 72 in the appropriate rotational direction to cause the electrode holder 56, and hence the corresponding electrode 24, to move closer to the surface 16 of the fluid 14. In this manner, an appropriate distance 74 can be maintained between the distal ends 24b and the surface 16 of the fluid 14, sufficient to prevent arcing from occurring.
  • the apparatus 10 may be operated as described herein to produce colloidal silver. Further, since opinions may differ as to what constitutes a true colloid and what does not, applicants note that the silver-based solution produced by the apparatus 10 has been found to possess all of the several known benefits of silver, including bactericidal benefits and anti- inflammatory benefits. Accordingly, the phrases "silver-based solution,” “solution of suspended silver,” “silver suspended in solution,” and equivalent phrases, as used herein, shall be construed broadly to refer to colloidal silver as well as suspended silver that may not constitute a colloid by some definitions. It will be appreciated that the container 12 may be referred to as a containing means for containing a quantity of fluid 14 therein such that said fluid 14 includes a free upper surface 16.
  • the upper electrodes 24 may be described as an upper, silver electrode made of silver element and having a first end and a second end.
  • the electrode holders 56 and the female-threaded mounts 58 may be described collectively as a holding means for (i) holding the first end 24a of the silver upper electrode 24, and (ii) holding the second, distal end 24b of the silver electrode 24 within 0.5 inches of the free upper surface 16 of the fluid 14 when said fluid 14 is contained within the container 12.
  • the power transformers 30 are controlled by one or more timers 31 as shown in FIG. 2, said timers 31 being electrically connectable to a standard "AC" outlet shown schematically at 33.
  • Each power transformer 30 may be described as a power means electrically connected to the holding means (mounts 58 and electrode holders 56) and to the lower electrode 26 for (i) conveying electrical current through said holding means to the upper, silver electrodes 24 and to said lower electrode 26 in a manner sufficient to produce a voltage difference between said upper and lower electrodes 24 and 26, and (ii) thereby causing particles of silver to separate from the silver electrodes 24 and enter the fluid 14.
  • the impeller 40 may be referred to as a dispersing means for dispersing the silver particles more evenly throughout the fluid 14 such that a higher quantity of suspended silver particles in solution can be produced per batch. As shown most clearly in FIG. 1, rotational movement of the impeller 40 causes the fluid 14 to flow in internal currents 41 that swirl around the container 12 and cause the dispersing of the silver particles.
  • the impeller 40 may further be described as a means for agitating the fluid 14 at a substantially continuous and substantially constant rate.
  • the suspended silver particles would tend to remain in an upper layer of the fluid 14. As the silver particles become more concentrated within that upper layer, the conductivity of the fluid in contact with the upper electrodes 24 increases substantially, thereby reducing the electrical resistance, which reduces the rate of production of suspended silver particles.
  • the agitation of the fluid 14 prevents the suspended silver particles from aggregating in the upper level of the fluid 14, and disperses them generally uniformly through the fluid 14, with the result that more suspended silver can be produced per batch, and at a faster rate.
  • any method of agitating the water could be utilized in lieu of the impeller 40 as desired.
  • a circulation pump (not shown) could be utilized in an appropriate manner known to those skilled in the relevant field to cause the fluid 14 to be pumped in a circulating flow, along a flowpath that could either be confined to the container 12 or might alternatively extend beyond the container 12.
  • a further alternative would be to place an air hose into the fluid 14 to dispense air bubbles throughout the fluid 14, thereby agitating the fluid for the benefits described above.
  • the impeller 40 is preferably disposed in a central location of a horizontal dimension of the container 12.
  • the motor 43 is selected, based upon the viscosity of the fluid 14 and the size of the container 12, to be capable of rotating the impeller 40 at a rotational velocity sufficient to agitate substantially all of any fluid residing in the container 12.
  • the electrode holders 56 with their throughbores 60, constitute a means for holding the first end
  • the air fan 36 may be replaced with an air blower, or any other suitable device capable of causing the airflow described herein by operation of the fan 36.
  • the fan 36 may be described as a humidity-reducing means for reducing humidity of air residing within the container 12 above the fluid 14.
  • a preferred method for producing a solution containing silver comprises the steps of:
  • An additional and alternative, preferred method for producing a solution containing silver comprises the steps of: (a) establishing an electrical circuit comprising a current source, and a first conductor electrically connected to said current source and a second conductor electrically connected to said current source, wherein said first conductor resides spaced apart from said second conductor, wherein the first conductor is made of silver element;

Abstract

La présente invention concerne un appareil et un procédé de production d'argent colloïdal. On utilise en l'occurrence une cuve de grande capacité (12) dont le couvercle articulé (18) porte, d'une part un agitateur rotatif à hélice (40), et d'autre part plusieurs jeux d'électrodes (22) électriquement raccordées à un transformateur électrique (30). La cuve étant partiellement remplie d'eau, la fermeture du couvercle met les jeux d'électrodes en communication avec l'eau selon un agencement défini, l'hélice de l'agitateur restant plongée dans l'eau. Certaines des électrodes constituent un fil d'argent (24). Les transformateurs électriques fournissent en courant les électrodes, de préférence en courant alternatif, sous des tensions suffisantes pour provoquer le détachement de particules d'argent du fil d'argent et leur entrée dans la solution à un état stable, en suspension. L'agitateur est mis en rotation, de préférence en continu, de façon à empêcher l'argent de rester dans les couches supérieures de l'eau, ce qui permet une dispersion plus uniforme des particules d'argent dans l'ensemble du volume d'eau.
